Pipeline survey and freespan correction, Bach Ho

The Bach Ho Gas Pipeline is located at the South Coast of Vietnam in the province of Vung Tau and comprises a 16" pipeline installed in 1994. The 16" pipeline is one of the main production lines of Petrovietnam Gas Company (PVGAS) and important for the supply of natural gas to electrical power plants, production and export of LPG and other domestic users.

Boskalis Offshore was awarded a contract for rectification works on the 5 km shore approach section of this pipeline. The scope of work for this project consisted of two main activities. In the first place a hydrographical multibeam survey had to be executed to determine the exact location and extent of exposed/freespanning pipeline. Secondly these locations would have to be protected by means of rock installation. The project was completed by the end of July 2004, in good time and to the Client’s satisfaction.

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.

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.
