DREDGING PROFILE ABOUT US
DREDGING PROFILE OUR SERVICES
SHORELINE PROTECTION
Rotawn constructs and maintains shore protection
structures including jetties, groins, seawalls,
breakwaters, and bulkheads in order to protect the
coastline and the navigable water channels that
can reach down to 100 meters. Early shore
protection measures included jetties and groins
constructed perpendicular to the shoreline for the
purpose of lessening the impacts of erosion by
reducing the rate of sediment transport along
vulnerable coastlines.
Rotawn has invested heavily in procurement of world
class next generation marine equipment for secured
shoreline protection.
Our clients recognize our first class professional mode
of operation & safety measures applied in ensuring
that we don’t end up causing erosion instead of
protecting the shorelines.

SAND FILLING
As an industry leader in our chosen fields, we
have gone beyond the limitations of the private
sector to the public sector.
We ensure that the appropriate CSD & Booster is
used to optimize resources as well as meet up
with client project deadline.
This in turn is achieved by availability of spares
and parts ranging from suction/discharge pipes
to all hydraulic & mechanical arts.
With our track record, we have shown that we
can deliver any sand filling job, within record
time.

SAND STOCK PILING
The construction industry relies heavily on hydraulic
marine sands for part of its aggregate mix in the
production of concrete. Sand grain of different sizes
and composition are required by builders and
contractors to execute their projects.
We have the capability of dredging various sand
stock pile types to meet the needs of the
construction industry. Strategic stockpiles have been
pumped for various ventures.
This service is central to our activities. The Sand stock
piling activities is backed up by adequate feasibility
studies and economic viability tests.
CHANNEL CLEARING
As part of our dredging services, Rotawn has
also specialized in canalization with new fields
of tasks which include deepening, widening
and maintenance of harbors and waterways,
dredging access channels, sand wave removal
and reduction of canalization blockage.
Canalization requires absolute precision and for
this reason, our operations are carried out with
high precision and the very highest standards of
safety, quality and environmental care, in line
with the demands of the oil and gas operators.
With our fleet of equipment, we offer credible,
tested and professional services

LAND RECLAMATION
Rotawn with its partner Kariala Konsult has acquired
extensive, worldwide experience in geotechnical and
geophysical site investigations, surveys, studies,
design, specification and supervision for:
Coastal and port developments including land
reclamation and beaches
Maintenance of port approach and navigation
channels, turning basins and berths
Civil works such as immersed tube tunnels,
pipelines and outfalls
Minerals extraction
Beach nourishment for the purposes of coastal
defense.
The global nature of Rotawn’s activities has provided
comprehensive experience of the wide variety of
dredging methods and types and sizes of dredging
equipment. Frequently, the reclamation (or beach
nourishment) works are accompanied by structures
such as revetments, to stabilize them once in place.
Again, Rotawn’s expertise in these areas is
unparalleled.
Rotawn also has experience of the survey equipment
and methods used for monitoring and controlling
dredging, reclamation and spoil disposal operations
as well as for the determination of quantities for
payment. We utilize state-of-the art numerical
modelling software, both developed in-house and
commercially available software, to model the
potential impacts of the dredging and reclamation
works on the wider marine environment, based on a
simulation of the hydrodynamic and sediment
regimes in and around dredging and reclamation
works.
