BRAVE TERN MAKES START ON HORNS REV 3

Fred. Olsen Windcarrier vessel Brave Tern is currently mobilising in Esbjerg for the installation of the 49 V164-8.0 MW MHI Vestas turbines on the Horns Rev 3 offshore wind farm. The first nacelles with MHI Vestas’ new logo arrived in the port in mid-June. A2Sea vessel SEA INSTALLER was booked to do the work but is still installing the 42 SWT-7.0-154 Siemens Gamesa tur-bines on the Rentel offshore wind farm in Belgium. Jan de Nul vessel Vole au Vent is also mobilising for work on the Horns Rev 3 site. She will be installing the tran-sition pieces on the monopile foundations which were installed by DP2 INNOVATION earlier this year. The turbine installation work is due to completed by early 2019 with full commissioning of the site before the end of the year. It is not known whether SEA INSTALL-ER will join the project when it has finished on Rentel.

FIRM BED FOR JACK UPS AT ESBJERG

Danish marine contractor Peter Madsen Rederi A/S (PMR) has successfully completed another stone bed installation job for jack-up installation vessels. The new set of stone beds were constructed in the port of Esbjerg in Denmark and completed well ahead of schedule. Working with a very tight time schedule, PMR was tasked with the construction of a new set of stone beds for the safe loading of the turbines for the Horns Rev 3 offshore wind farm, DK. The stone beds will be used as a stable platform for the jack-up instal-lation vessel and had to be installed in time for the first load-out. The project comprised of capital dredg-ing of approx. 30,000m3 of seabed, dumping of the material offshore, procurement, transport handling and installation of around 20,000 m3 of stones as well as extensive multibeam surveying.

HEAVY LIFT VESSEL APOLLO ON SEA TRIALS

GeoSea’s new build heavy lift vessel Apollo has started sea trials. The jack-up vessel was built in the Uljanik JSC Shipyard in Pula, Croatia. The vessel is a GustoMSC NG 5500X design and is 87.5m loa and 42m in beam. It has a maximum draft of 7m. Apollo has four 106.8m legs which will allow it to operate in water depths up 70m. The legs use the GustoMSC Electrical Rack & Pinion system. Its cargo capacity is 4500 tons with a 2000m2 deck space. Apollo was ordered at the same time as Living Stone and the two vessels were due for delivery in 2017. Both have been designed as ‘green vessels’ with ‘dual fuel’ main engines, solar panels and wind turbines on board, use of biodegradable grease and oil and heat recuperation, in order to operate them with the lowest possible fuel consumption while also keeping CO2 and NOx & SOx exhaust to the strict-est minimum. Both ships will have a Green Passport and a Clean Design notation. Apollo is ABS classified and also has the WIND-IMR notation.

ALICAT MANAGEMENT BUY OUT COMPLETED

The management team of Alicat Workboats Limited, concluded a management buy out (MBO) of Richards Dry Dock and Engineering group from its parent com-pany Gardline Group. Alicat, based in Great Yarmouth, was established in May 2009 as a subsidiary to ship-builders and engineers Richards Dry Dock and Engi-neering Ltd and is a provider of bespoke marine, gen-eral engineering and electrical services. The MBO will see all the group's operations consolidated back to its Main Great Yarmouth facilities. Alicat Workboats, along with its sister company South Boats IOW Ltd has constructed a large number of offshore wind Crew Transfer Vessels (CTVs) in Europe in recent years, and has a track record of building, servicing and repairing vessels in all other marine sectors. The group will retain the current branded design range of Alicat and South Boat CTV's all of which are still available to be built at the Great Yarmouth facility or under an ap-proved licence agreement.

CHANGE OF VESSELS ON BEATRICE OWF

A milestone was reached yesterday when Seaway Heavy Lifting’s vessel Oleg Strashnov completed the installation of the 84 four legged jacket foundations on the Beatrice Offshore Wind Farm, UK. The vessel utilised its 5000 ton crane to lift the jackets which weigh between 1000 tons and 1150 tons each. She installed the first jacket in August last year. Each foundation has been installed on piles which were placed by Stanislav Yudin which started the work in March last year, completing the last pile in early December.

Pacific Orca has arrived on site today to commence with the installation of the 84 SWT-7.0-154 (Siemens Gamesa) turbines. The vessel has been mobilising from Nigg Energy Park which is the construction and marshalling port. Pacific Orca is 160m loa and has a lift capacity of 1200 tons. She has recently completed the installation of the 11 turbines on the Aberdeen Offshore Wind Farm. Work on Beatrice turbine is expected to be completed by March 2019.

DP Gezina is also due on site. The 70m vessel will be providing accommodation support during the commissioning of the turbines. First power from the site is expected around the end of July or early August.

Siem Aimery recently left Beatrice where she had been providing accommodation support for Siem Offshore Con-tractors' technicians carrying out testing and remedial work to array cable strings as well as post burial surveys on the array cables. Siem Aimery is currently in Hartlepool collecting the next load of array cable from the JDR manu-facturing facility. Stril Server, which was fitted with an SMST Walk to Work gangway earlier this year to reduce the need for CTV support, has now arrived on site to provide accommodation support on site during the array cable work.
