Those berths come on top of
five already slated for construction
between 2005 and 2006, making a
total 15 new berths to be added to
PPT over the next five to seven
years and boosting annual capacity
by 50% to 31M TEU.
Singapore handled a record
20.6M TEU in 2004 and volumes

Refitted For RussiaA novel use has been devisedfor FAIRMOUNT MARINE’S semi-submersible barge OceanSeal...
The Fukada-owned, 24,000dwt
barge is being adapted to work as a
mobile storage facility for stone and
other materials, which will be used
to prepare the seabed for an
offshore concrete drilling platform
at a project being carried out by
VAN OORD near Sakhalin Island. The
aim is to harness oil and gasreserves for delivery to Asia Pacific
and North America.
As we went to press, the
Fairmount-managed, Chinese-
owned tug Hua An was about to
tow Ocean Seal to Singapore,
where it will be fitted with special
deck protection and extra
accommodation. The tug and barge
should arrive on site in June,

Lack OfInterest?Port of Rostock MD DR. ULRICHBAUERMEISTER was the onlyEuropean port director toattend a recent hearing of theEU’s Marco Polo II (MP-II)programme...
The meeting was called by the

MaasvlakteDelayOfficialDutch transport minister KarlaPeijs has admitted thatconstruction of Rotterdam’sMAASVLAKTE 2 will be delayedat least 18 months
In January, the Raad van State
ruled that the Dutch government
had to re-assess plans for the
expansion project because ‘it had
not followed the properprocedures under the European
Habitat Directive and that
construction of Maasvlakte 2 could
pose a threat to habitats in
northern Dutch Waddenzee.’
At the time of the ruling, Ms.
Peijs argued that the procedural
failures would be “repairable” in a
reasonably short period, but she’s
now had to backtrack. It’s a move
that could prove damaging –
shipping agents claim Chinese lines
will lose interest in setting up
dedicated terminals.

Three DaysIn Rotterdam
This year’s CEDA DREDGINGDAYS promises to botheducate and entertain, witha packed programme of
technical papers, anexhibition, partners’programme and social events
Themed Dredging: The
Extremes, the congress will be
held in conjunction with Europort
Maritime 2005 from November 2-
4 in Rotterdam’s Ahoy exhibition
centre.
Dredging projects frequently
have to meet extreme
requirements, or be carried in
extreme physical or regulatory
environments. As society presents
new challenges to the industry, it’s
continually pushed to makeadvances in accuracy,
environmental safety, cost
effectiveness and strength.
That often results in novel
approaches, innovation,
progressive improvement and the
development of specialized
dredging equipment and
techniques. And that’s Dredging
Days’ focus, with the aim of
promoting discussion and the
exchange of ideas, experience and
technology.
IN DETAIL♦ Papers – The conference hasbeen extended to two and a half
days due to the quality of
response to the call for papers
and includes seven sessions: (i).
Dredging In Complex Regulatory
Environments; (ii). Jetting; (iii).
Case Studies; (iv). Environment;
(v). Advances In Science &
Technology Part 1 and (vi). Part 2;
(vii). Technical Progress.
♦ Technical Visit – On
Wednesday afternoon, November
2, delegates can view the Slufter,
the world’s largest confined
disposal facility for dredged
material, located in the Port of
Rotterdam’s Maasvlakte industrialarea. The site also has facilities for
sand extraction and dredged
material ripening for beneficial
use.
♦ Exhibition – Held in the
technical session room foyer and
open throughout the conference.
♦ Partners’ Programme –
Includes a visit to the
Smaakcollege, where participants
will receive a master class in
preparing ‘high tea’ – and get to
sample it too!
FINALLY...If all this has served to whetyour appetite, book your place
online now at
www.dredging.org.
The fee (including VAT which
can be reclaimed from the Dutch
tax authorities using forms
available at the registration desk)
is €335 for CEDA, EADA and
WEDA members, €450 for non-
members, €50 for undergraduate
students and speakers, while PhD
students get a 50% discount. It
includes all conference sessions,
free entrance to EuroportMaritime 2005, a full set of
conference documents, morning
coffee, lunch, afternoon tea and
entrance to the CEDA Netherlands
reception (to be held on
November 3). Wednesday’s
technical visit, however, will cost
you an extra €50.

Jointly owned by Lukoil and FTS / Hofftrans the new facility increasesthe number of heavy fuel oil suppliers located at Europe’s main oil hub
and strengthens Rotterdam’s strategic position against its Russian rivals.
The port and operator will invest a combined €21M through to 2007
to improve the terminal’s bunkering and ship-to-ship transfer facilities,
while tank storage capacity will be increased from the current 40,000m3
to 120,000m3.

Dredging contractors have had years to
come to terms with it, but on May 19thAnnex VI of MARPOL 73/78 becomesmandatory for vessels over 400gt
Annex VI sets limits on sulphur oxide (SOx)
and nitrogen oxide (NOx) emissions from ship
exhausts and prohibits deliberate emissions of
ozone depleting substances.
According to an EU statement, this will
equate to ‘at least 2,000 fewer life years lost
through long term exposure, 750 fewer deaths
from short term exposure and 300 fewer
hospital admissions for respiratory illness.’ And
while in comparison to the rest of the world’s
merchant fleet, dredgers’ contribution to those
figures is vanishingly small, contractors would
probably agree that it’s no bad thing.
Annex VI is at least a level
playing field: it sets a global cap
of 4.5% m/m on the sulphur
content of fuel oil and calls onthe IMO to monitor fuel’s
worldwide average sulphur
content. It also establishes
special ‘SOx Emission Control
Areas’ with more stringent
controls – including the Baltic
Sea and North Sea. Sulphur
content’s cut to 1.5% m/m in
such areas, or alternatively ships
must fit an exhaust gas cleaning
system or use other
technological methods to limit
SOx emissions.
Not surprisingly, the latter have
been flocking to market recently.Interestingly, especially as
there’s been controversy
elsewhere over the amount of
administration and paperwork
involved in compliance, DPC’s
not received one peep of protest
or concern from contractors.
This may well be that given the
huge number of environmental
restraints the industry’s already
burdened with, Annex VI is
viewed as a minor problem. But I
think it’s because dredging
people are simply among the most responsible
in the maritime world.This month’s photo? Where else but the
launch of d’Artagnan (see page 24) on April
22nd? Apologies that DPC’s a little late as a
result, but we simply couldn’t publish this
month’s issue without reporting on the great
event.

Local authorities in the Lorraine and Rhone Alps regions ofFrance plan to re-launch a project to establish a Rhone-Rhinewaterway link
The announcement came eight years after a similar project wasdropped by Lionel Jospin’s government, but Rhone Alps region
transport chief Bernard Soulage is confident of success.
“While the previous project provided for a waterway link via the
Doubs, we suggest a new link via the Moselle which will be more
economical and have less environmental impact,” he said.
Such a link could reduce truck traffic volumes through the Rhone
Valley corridor by transferring cargo to the Rhone waterway, “but this
will only be feasible if this waterway has an outlet in Northern
Europe,” added Soulage. The waterway would be able to handle large
container barges and permit transit all the way from Marseilles to
Rotterdam.More info at www.vnf.fr

DPC Port & Harbour Maintenance
In Rotterdam a new constructionmaterial’s being tested that’s designedto improve the integrity of concrete
blocks in a breakwater’s protective wall.Under constant exposure to extreme
wave forces, most breakwaters requirefrequent maintenance and repair – and thetwo that mark access to the IJmuiden sealock complex and the North Sea Canal areno exception.
Last October a weak section in the
southern breakwater was spotted, givingthe Dutch Directorate of Transport andWater Management’s (Rijkswaterstaat)Innovatie Test Centrum (ITC) a chance touse the new ‘carbon concrete’ blocks. It’sITC’s task to test innovative products andmaterials in real projects in close co-operation with manufacturers.
Six carbon concrete blocks were used,the new material being similar to normalconcrete in that it’s made with aggregates,but with the bituminous product C-Fix
used as a binder instead of cement. C-Fix(carbon fixation) was developed overthree years by Shell in response to theKyoto Protocol and is being marketed bysubsidiary C-Fix. It uses oil refineries’residue that’s traditionally used as heavyfuel for large ships and power plants, butwith the drawback of high carbon dioxide(CO2) emissions. Fixing CO2 to producethe C-Fix binder is thus extremelybeneficial to the environment: for everyton of C-Fix, 2.5tons of CO2 is fixed –IJmuiden’s six blocks represent a totalreduction of 33tons of CO2.
IJmuiden’s extreme wave conditions
meant the blocks also had to have a veryhigh density, so Minelco’s special heavyiron oxide aggregate, ‘magnetitemagnedence,’ was used instead of theusual sand and gravel, resulting in a3.9kg/m3 block density.
This test project is the first time C-Fixhas been employed as a heavy duty portconstruction element and the 45-tonblocks are the largest and heaviestelements built with C-Fix so far. They’ll bemonitored by Rijkswaterstaat, in close co-operation with C-Fix and Minelco, to seehow they behave under the influence of the sea. Early indications are positive – the
blocks appear extremely resistant to saltand sea water corrosion.
SPECIAL SUPPORTThe destructive force of the sea also had
a major bearing on the design of aningenious falsework solution developed by
RMD Kwikform (RMDK) to support aconcrete deck slab for the Royal NationalLifeboat Institution’s (RNLI) newboathouse station being built by Dean andDyball at Tenby on Wales’ Pembrokeshirecoast.
The 25.6m-long x 21.7m-wideboathouse slab is cruciform in plan andincorporates a 19.5m-long trough, intowhich the new lifeboat will be ‘parked,’plus cantilevered ‘wings’ on both sidesand at the rear. The slab is supported by19 piles and comprises over 450m3 of concrete, placed in six separate pours andweighing a total of over 1,200 tonnes.
Using the conventional method of supporting the slab from below wouldhave subjected the falsework to Tenby’sdangerous tidal conditions, possiblytwisting and mangling any temporaryworks. Instead, it was decided to suspendthe falsework above the sea’s wildlyfluctuating high tide mark from a networkof 813mm diameter piles. Pile caps wereused to support pairs of H33 girders,which in turn supported a gridwork of universal beams and RMDK Super SlimSoldiers, from which suspended ties werehung to support the soffit. The H33girders were supported by tapered steel
legs attached to steel stools welded to theinside of the circular steel piles.
While the H33 girders provided supportfor the concrete pours, to prevent themfrom hampering soffit erection and steelfixing, huge friction collars were placed

combined wall was considered the mostappropriate construction method.
Client Public Works and GovernmentServices, Canada and consulting engineersEastern Designers evaluated variousconstruction methods before choosingsheet piling, which was considered themost economical and the most suitable forthe shallow bedrock conditions and thewharf’s expected lifespan.
The combi-wall’s HZ king piles and AZsheet piles were driven 1.5m in front of
the existing structure and the spacebetween the new and existing wharf faceswas backfilled. The concrete deck of theinterior portion of the quay was removed,the grade raised and a new concrete andasphalt wharf deck created. The shorelinearea between the north and south wharf was also closed up with a sheet pilestructure.
During a typical ten-hour shift thecontractor was able to drive roughly fiveHZ king piles and five AZ sheet piles,driving taking seven weeks in total.
FENDER THOUGHTS“Most harbour facilities are built for
life spans up to about 100 years, buttechnical and market development is sorapid that fender systems are designed forlife cycles of 20 to 30 years.”
That was Fentek marketing directorMike Harrison’s comment as he openedthe firm’s Middle East regional office inDubai in late 2003 as the area began toboom. With older ports and harboursbeing expanded and spruced up, oil priceshigh and economies stable, the strongconsumer and industrial demand sawMike’s new office expanding rapidly –sales were quickly up several times the
normal figure for the region.“Fentek had historically served its
Middle East customers from Europe,”Mike continued, “but opening the Dubai
Design MattersSeveral FENTEK fender systems haverecently been type-approved under astrict PIANC protocol
Brought into force in April 2002, the
protocol covers fender design practices and
aims to ensure that published performance
figures from all type-approved sources are
measured using the same methods and from
the same datum.
It addresses many areas critical to fenderperformance, including a definition of the rated
performance data (RPD, which defines the
minimum requirements for manufacturers’
published performance figures) and the test
apparatus and performance testing procedures
to be used.
Fentek’s Singapore factory, Trelleborg
Hercules, began testing the Fentek Super
Cone, Cell Fender, Unit Element, and Arch
Fender systems in late 2002 and Germanischer
Lloyd was appointed to witness and verify the
results.
At the end of October 2004, Fentek’s entire
range of moulded fenders achieved type
approval status, making it ‘the firstmanufacturer worldwide to achieve this
milestone.’

The device transmits live video throughan umbilical cable to a topside monitorfor viewing and recording. ‘The camera
housing can be easily mounted on adiver’s helmet, put into a pipe for internalinspections, or attached to a pole handleto view the underside of vessels and seawalls,’says the firm.
The basic MC-1system incorporates‘a monochrome
camera
encased in a 500ft depth-rated, corrosion-resistant underwater housing and a 150ftcable. It has two different lighting options:an internal ring light made of highintensity LEDs or external 100 watt

DPC New Dredgers
At theBarkmeijershipyard in
Stroobos, Holland,a special trailing
suction hopperdredger (TSHD)was launched on
April 7 for La Rochelle-based DragagesTransports et Travaux Maritime (DTM).Called André L after André Libaud, thefounder of DTM’s parent firm GroupeLibaud, she was christened by hisdaughter Mrs. Robert Libaud – and she’sspecial because of her relatively high ladenspeed of 13 knots.
It’s a vital design factor enabling her tosynchronise dredging cycles with the tides– tidal ranges are very large off theAtlantic coast of France where she’ll be
dredging sand and missing a port entry athigh tide could mean several hours of lostworking time.
Her hull plays an important part inobtaining the high speed and model testswere carried out in the Wageningen basins
of the Maritime Research InstituteNetherlands (MARIN) to optimize theshape.
EQUIPMENTAndré L’s equipped with a Wärtsilä
6L32 main diesel engine driving a singleCPP propeller via a Wärtsilä gearboxthat’s equipped with a ‘power tack in’(PTI) facility. Driven by an 875kW electricmotor and coupled to the gearbox via ahydraulic clutch, the PTI serves as aredundant means for propulsion: in anemergency, it will bring the ship to a safeport at low speed. Wärtsilä have alsosupplied a 6L20 diesel engine as anauxiliary generator that can be connectedto the PTI.
The TSHD’s dredging installation wassupplied by Nijkerk-based Damen
Dredging Equipment and consists of asingle 600mm suction pipe with anintegrated, electrically-driven submersiblepump, giving a maximum dredging depthof 40m.
She can unload either by dumping
through four bottom doors or via anelectrically-driven shore discharge pumpthat can empty the hopper through foursuction openings in the bottom doorrecesses. And the versatile shore discharge

BUILT TO COPE
There’s often heavy swell in the CaspianSea’s Port of Hazar’s approach channel –frequently with wave heights over 2m –but Damen Dredging Equipment’sspecially designed DOP plain suctiondredger (PSD) is ‘performing beyondexpectations,’ say owners Dragon Oil(Turkmenistan).
Dragon, who are headquartered inDubai, use Hazar to support offshoreactivities. The custom-built DOP-PSD wasdesigned, constructed and delivered inonly 10 weeks as fast developing siltationin the region was creating urgent logisticproblems – large suppliers were having
difficulty gaining access.The port’s also remotely situated anddifficult to reach, necessitating a simple,sturdy and maintenance-friendly dredger.Site investigations by Damen resulted inthe design of a long – over 30m –dismountable pontoon equipped with aDOP2320 submersible dredge pumpsuspended on a hoisting wire and workingover a swell compensator. The pontoon’spositioned in the wave direction and willthus always rest on a minimum of twowave crests, ensuring only verticalmovement and no hampering of dredgingactivities due to rocking.
POWER & FELIXIBILITYThe vessel comes with a 500m floating
pipeline, four six-ton winches for steadymooring in heavy weather and has its own10kVA generator to allow round-the-clockoperation. A deck-mounted 314kW Scaniapower pack drives the DOP pump,winches and a 200m3/h 50mwc jetwaterpump that feeds the suction head,assisting it to remove fine sand and silt.
The dredger’s composed of standardcontainer pontoons that made for simple,fast delivery by box ship and trucks. It’scoupled together via a proven system,
ensuring reliable assembly in remote areas.And of course the pontoon dimensionswere carefully selected to ensure sufficientfreeboard in heavy swell.
After transport to Turkmenistan, thedredger was assembled by its new crew –
under direction of a Damen field engineer– within two weeks and the crew thentrained for a further two weeks by aDamen dredgemaster.More info at www.damendredging.com.]

FINALLY...IHC Holland Merwede is building two
electric mining CSDs for the Moma heavymineral project in Mozambique.
Moma’s mining process will be basedon proven technology, comprising anartificial mining pond with double dredgeoperation and a floating plantconcentrating and separating the mineral
sands. IHC will also provide a trainingprogramme enabling local personnel toboth work with and maintain thedredging equipment.
The contract was awarded in Februarythis year by Mauritius-based joint ventureMultiplex-Bateman and the dredgers –being built at IHC Holland BeaverDredgers Sliedrecht yard – are designed to
allow for simple, local assembly. That’sbecause access to the site will pose logisticchallenges. Some of the larger dredgingcomponents will have to be beach-landedand, as this is written, an access roadfrom beach to site still has to be built.
It’s a similar story for the miningcomplex and its equipment – the export
jetty, product storage and loadingfacilities, electrical generation / transmission equipment and personnelaccommodation are also underconstruction. But Moma has resources tosustain annual production of around615,000 tonnes of three ilmenite productsfor 80 years. Significantly, it’s located inone of the poorer areas of the country andonce in full production by end-2006 willprovide employment for about 500workers.More info at www.ihcholland.com
Tech SpecsThe electric dredgers have thefollowing...♦ Length Overall – 47m
♦ Length Over Pontoons – 39.5m
♦ Breadth Over Pontoons – 9.5m
♦ Average Draught – 1.45m
♦ Max Dredging Depth – 15m♦ Suction / Discharge Pipe Diameter –
500mm / 550mm
♦ Installed Dredge Pump Power – 750kW
♦ Installed Cutter Power – 280kW

DPC Major Port Construction Projects
Christened HIT-2 by ownersAssociated British Ports (ABP) todistinguish it from the existing berth,
the £44.5M project is not the Port of Immingham’s only development – as youread this, construction and dredging areunderway in the Outer Harbour to create anew £35M ro-ro terminal for DFDS Tor
Line. And there’s more to follow. On theother side of the Humber River, at ABP’sPort of Hull, the UK government’s givententative approval to the £35M Quay 2005development that will see a two-berthshort-sea container terminal built, enablingthe port to accommodate the new breed of larger feeder vessels.
It will also enable ABP to relocate theircontainer terminal from within the VictoriaDock, plus expand a paper productsfacility. Quay 2005 will take about twoyears to become operational and is likely toget full environmental permission later thisyear.
PROJECT PLANNINGEnvironmental considerations have been
at the top of the list during planning for allthree projects.
“We began consultations over three
years ago,” ABP’s engineering managerGordon Bulter told me, “talking withEnglish Nature, the Royal Society for the
Protection of Birds, local authorities andof course government agencies. As aresult, we’ve won their co-operation anddidn’t need to go to a public enquiry.”
To compensate for the environmentalimpact, ABP are spending £1.5M to create
a managed retreat offering floodprotection and a natural habitat forwildlife at two nearby sites, 14ha at
Chowderness and 54ha at Welwick. Thework’s due to get underway this monthand will be carried out by HIT-2’s majorcontractor, Edmund Nuttall, who’ll designand build a total of 30,000m2 of revetment protection with earthwork

embankments using 119,000m3 of material at Welwick and 49,000m3 atChowderness.
Humber International Terminal wasfirst mooted in 1988 and a HarbourRevision Order was granted in 1990,though nearly a decade passed before thefirst quay, HIT-1, became operational.
“HIT-2 got the go-head in 2003,”Gordon continued, “and Nuttall arrivedon site in August last year. It’s scheduledfor completion by mid-September this
year.”
WORK IN PROGRESSFor such a complex job, progress has
been fast and not without challenges, asNuttall’s project manager Simon Tannerpointed out – “We had to co-ordinate thework so as not to disrupt the port’soperations,” he said.
“When it’s complete, the jetty will be520m long and able to berth ships of upto 160,000dwt,” Simon added. “In total,there’re 123 tubular piles, each 1,020mmin diameter, 1,650 tons of rebar and7,200m3 of concrete.”
There are also no fewer than 430 pre-cast items, including pile caps, transverseand both long and deck beams. Itresembles a jigsaw on a giant scale and tocope, Nuttall are using the 350-tonnecapacity crane barge Marlin to lift and
position the huge pieces.“Like HIT-1, we’re using Fentek
fenders, 18 of them, which will help withparts interchange,” Simon continued.“The jetty also has an integrated crane railfor the permanent ship unloaders andwe’re using the new Dutch Edilon system.It’s an ‘elastomeric’ bearing that supportsthe rail and prevents corrosion. The pre-formed channels have cut the need fordiamond drilling, so it’s been quicker toinstall and should last longer.”
The unloaders are due to arrive frommakers DEMAG as you read this.
“We’ve gone for slewing cranes,” saidGordon, “which can cope with othercargoes, not just coal. They’re among thebiggest in the world, will lift 50 tonnes at50m radius and themselves weigh 525tonnes – even the hoppers weigh 200tonnes, unladen.”
STACKING & STORAGEBoth HIT-1 and HIT-2 benefit from apurpose-built railhead and will also havetwo rail-mounted stacker-reclaimers, eachcapable of shifting 5,000 tonnes of coalper hour.
“The average ship coming to HIT-1 –and later to HIT-2 – carries around70,000 tonnes and averages a two tothree-day turnaround,” Gordon told me.“Right now, HIT-1 is handling 5M tonnesa year, which is unloaded into hoppersand then onto lorries. Phase 1 of HIT-2will up capacity to 6.5M tonnes and thesecond stacker-reclaimer will take that to
9M tonnes. With further investment in therailhead, it should go up to 10M tonnes.”The initial and second stacker-
reclaimers will not just speed throughput,but will also deliver coal – about 15% of a ship’s cargo – direct to trains as well asto the new storage area being builtalongside HIT-2’s quay. Nuttall areconstructing the foundations and thefacility will measure 700m by 300m, overhalf of it reclaimed land, and hold wellover 1M tonnes.
“The settling ponds for coal run-off have been built,” said Gordon, “andwe’ve a huge pollution control system
with no less than 60 sprays to keep thedust down.”
FINALLY...As you read this, UK Dredging is busy
extracting 2.6M m3 in the first phase of work to create the Outer Harbour ro-roterminal that will service 20ha of newport area. It will have an alongside depthof 10m at LWMS and cost £35M in total.
Nuttall are responsible for the 240m-long finger pier – which again will befitted with Fentek fenders – while theMacGregor Group are manufacturing thetwo massive linkspans, which, at 80m
long are among the world’s largest andwill attach the pier to a floating, 117m-wide pontoon.
“The pier will be able to berth threeships, one seaward and two landward,”Simon said, “and we’re also carrying out

Both HIT-2 and the Outer Harbourproject have seen UK Dredgingco-ordinate an extensive campaign, asgeneral manager JEFF NEALE relates
At HIT, we initially created a bund encasing
75,000m2 of foreshore and formed bydredging a trench around the perimeter of the
site, back filling it with dredged sand and
finally overfilling with chalk and rock armour
trucked in to form the bund wall.
This first phase was carried out October to
December 2001 with continuous survey
monitoring to ensure that the design profile
was achieved. UKD sub-contracted Humber
Work Boats’ (HWB) cutter suction dredger
(CSD) John M for the trench work, the
70,000m3 of silt being pumped into a pre-
dredged box offshore from where the trailing
suction hopper dredger (TSHD) UKD Marlin re-
dredged the material for sea disposal.
Phase 2 involved back filling the trench withsand won from the sunk dredged channel as a
beneficial use of the on-going maintenance
dredging programme – 50,000m3 of sand was
dredged and pumped into the trench by UKD
Marlin.
HWB’s crane barge Mortlift was moored
adjacent to the site and UKD Marlin would
moor alongside the barge and discharge her
cargo of 2,000m3 of sand through a floating
pipeline to the HWB vessel Rebecca M, where
the pipeline terminated in a T-shaped
spreading bar. Rebecca M would slowly move
down the channel laying a 4m-high bed of
sand within the trench.
The work was completed in late December
2001 and subsequently capped with chalkfrom landward. The berth box has been
partially dredged by UKD Marlin, but there
remains around 30,000m3 of clay to be
removed before the berth becomes
operational.
OUTER HARBOURWe’re dredging 2.6M m3 at the new ro-ro
terminal, to give a design depth of 10m below
Admiralty chart datum (ACD).
ACD approximates to LAT (lowest
astronomical tide – the lowest theoretical tide
possible at a particular location). MLWS at
Immingham, however, is around 0.9m above
ACD so at MLWS there’ll be around 10.9m ofwater at the terminal’s berths.
Following initial work by UKD Seahorse,
Cherry Sand and UKD Marlin, dredging of the
overlying silts & sands has been sub-contracted
to Westminster Dredging’s CSD Seine, which
is assisted on site by UKD Seahorse.
It’s a similar operation to HIT-2, the silt’s
pumped into a box outside the site for re-
dredging by UKD’s vessels, primarily UKD
Marlin.
Rohde Nielsen’s sub-contracted to dredge
the underlying clay to its final level. Their
bucket ladder dredger Ajax R, expected on site
this June accompanied by two split hoppers
and supported by UKD Seahorse, will do thework. And the clay will be disposed of at
licensed disposal sites near to the sunk
dredged channel.

the entrance widened to about 300m.“We’ve already carried out simulations
in Holland with ships’ captains and pilotsto ensure safe berthing,” Gordon added.
Again, it’s a complex project, copingwith the Humber’s 7m tidal range and co-ordinating with the dredging team.

DPC Environmental Aspects of Dredging
First set up in 1995to help addressissues concerning
dredged materialmanagement and disposal, the NDT hasbecome a vital task force.
Now it’s implementing a new Action Agenda that aims to promote thebeneficial use of dredged material, improveregional sediment management andstreamline regional operations.
But first...
A LITTLE BACKGROUNDWorldwide, a massive amount of
dredged material’s dumped at sea.According to the secretariat for theLondon Convention – the primaryinternational agreement covering oceandumping – roughly 150M to 400M tonnesof dredged material is disposed of eachyear in Convention waters. In the USalone, about 20% of the several hundredmillion cubic yards of sediment annuallyremoved from waterways, ports andharbours is dumped at sea.
Dredged material is a key focus of theLondon Convention and its contractingparties have developed extensive guidanceon best practice for its disposal. The USjoined the convention upon itsinauguration in 1975 and, as part of itsown programme, formed the NDT in 1995to help improve co-ordination of thedredging process.
The NDT, which aims to promotenational and regional consistency ondredging issues and provide a forum forstakeholders, federal, state and localagencies, comprises the following federalagencies:
♦ US Environmental Protection Agency(EPA) – co-chair♦ US Army Corps of Engineers – (USACE)co-chair♦ Maritime Administration♦ National Oceanic & AtmosphericAdministration’s National Marine FisheriesService and National Ocean Service♦ Fish and Wildlife Service, and♦ US Coast Guard.
The US Navy and the US Geological Survey also participate.
In most areas of the US – including theGreat Lakes, the Northeast and Southeast,Western Gulf, Southern California,
Northern California, Pacific Northwest,Pacific Islands and Alaska – RegionalDredging Teams (RDTs) have beenestablished. They comprise federal andstate agencies and other stakeholders andalso aim to improve dredged material
management and increase public educationand community involvement.
FUTURE AGENDAIn its first five years, the NDT addressed
several critical issues regarding dredgedmaterial management planning, thedredging review process, funding andscientific uncertainties.
In 2001 it sponsored a stakeholderworkshop to assess, and if necessary
adjust, its role in dredged materialmanagement. This resulted in a new actionplan: Dredged Material Management – Action Agenda for the Next Decade – which makes 22 recommendations on:♦ Beneficial use of dredged material♦ Regional sediment management♦ Emerging issues, and♦ Strengthening RDTs.
Let’s look at them in more detail... BENEFICIAL USES – Of the millions of cubic yards of sediment dredged in the USeach year, the majority’s dumped in openwater and confined or upland disposalfacilities. Yet a large amount’s suitable for
environmentally beneficial uses, includinghabitat restoration and creation, beachnourishment, aquaculture, forestry,agriculture, mine reclamation andindustrial / commercial development.
So why isn’t it being used in this way?Commonly cited hurdles include:♦ Increased costs♦ Need for earlier planning♦ Need for more widespreadco-ordination, and♦ Widespread misconception that dredgedmaterial is a waste and not a resource.
If the beneficial use of dredged materialis to become a viable alternative, theNDT’s determined to make it a priority atall levels. Funding must be increased, localplanning must be proactive in identifyingprojects, sponsorship and suitability andthe general public and stakeholders muststart to recognize that dredged material isa valuable resource and not just a wasteproduct.
Action Agenda Recommendations –
include guidance on beneficial use projects,the role of federal standards, guidance onhow to improve the USACE / EPAbeneficial use website and identification of factors needed to develop a beneficial usetracking system.SEDIMENT MANAGEMENT – Excessivesediment erosion, transport and depositionare estimated to cost the US aboutUS$16Bn a year.
Sediment overloading due to land andstream erosion is thought to contribute tohigh turbidity, loss of flood-carryingcapacity and sediment deposition innavigable waterways. And a shortage of
sediment also leads to coastal erosion,stream bank erosion and wetlands loss inmany areas. Yet many water resourceprojects designed to remedy local sedimentproblems create even larger problemsfurther away from the site.
NDT will now take measures to ensurefederal, state and local stakeholders canachieve sediment management in thecontext of watershed management andthat watershed planning incorporatesdredging. In this way, sources of sediment,beneficial use opportunities and fundingcan all be adequately addressed.
Action Agenda Recommendations –
include the formation of new localplanning groups (LPGs) to developdredged material management plans andto sponsor a national workshop onsediment management (planned for 2006). EMERGING ISSUES – Over the pastdecade such new legislation as theEssential Fish Habitat, Environmental Windows, and Total Maximum DailyLoad designations have created newchallenges for dredging.
To ensure that the review process isconducted in a timely, efficient andpredictable manner, planning strategiesmust be flexible enough to accommodate
emerging issues, while communication onthese issues must be open and early.
Action Agenda Recommendations –include guidance on how these issues affectdredging and dredged materialmanagement.
