Construction gas pipeline
Beachfield Upstream
Development

The BUD project entailed the construction of a 66 kilometer, 36" gas pipeline, 63 kilometers offshore and 3 kilometers onshore underground to the treatment facilities. The offshore pipeline runs from the east coast at Beachfield (Rustville), Guayaguayare, to the 'Cassia B' platform complex. At the NGC Abyssinia facilities, 3 kilometers off Beachfield, a new sludge catcher has been developed to separate the liquid or condensate from the natural gas. The condensate is separated from water and metered. The station is also designed to control the pressure of gas, as it enters into the land gas transmission system. NGC's existing 30" and 24" gas pipelines have also been diverted to the new Abyssinia sludge catcher.

Main Contractor Stolt Offshore Services, responsible for the installation of the 63 kilometers 36" offshore gas pipeline, contracted Boskalis for the associated landfall services, consisting of dredging the shore approach trench, preparation of the landfall site, pipeline pull-in services and, upon pipeline installation, backfilling of the trench. The preparation of the landfall site, including all concrete, construction and piling works was executed with local contractors, to ensure a maximum local content level.

Transport and installation turbine foundations offshore wind farm, Wikinger

The Wikinger offshore wind farm has been developed by Iberdrola in the Baltic Sea area, within the German Exclusive Economic Zone (EEZ). The offshore site is about 34 km northeast of the island of Rügen, and covers an area of roughly 50 km², within which 70 wind turbine generators (WTG) of 5 MW and one offshore substation (OSS) are being installed. The water depths for installation range between 36 and 42 meters. When completed the windfarm will deliver 350 MW electrical power to the German national grid. The transport and installation of the 70 WTG foundations and the piles for the OSS has been carried out by Boskalis.

monopile installation,
Veja Mate

Boskalis is close to completing one of its latest and most significant offshore wind projects - Veja Mate, in the German North Sea. The project involves handling and installing the biggest monopiles in the industry – weighing between 1,230-1,302-tonne a piece – using the biggest pile gripper frame and pile driving hammers in the industry with a brand new vessel, which also happens to be the biggest in the sector. Once complete, the offshore wind farm will produce over 1,6 TWh of green, renewable electricity annually.
