Construction Complete on Final Wind Turbine For Sheringham Shoal Offshore Wind Farm
The construction of 88 Siemens AG (Munich, Germany) 3.6-megawatt turbines at the 317-megawatt Sheringham Shoal Offshore Wind Farm off the coast of North Norfolk, England, was completed in July.

The Seajacks Leviathan has worked in tandem with a second jack-up vessel, GMS Endeavour, for the past five months to complete the erection of the turbines.

With 88 turbines in place and 46 turbines now connected and able to deliver electricity to the national grid, the wind farm is on track to be fully operational in September. The wind farm has been generating electricity since August 2011.

The remaining turbines are in various stages of mechanical and electrical completion, commissioning or testing before they can start generation.

Work will continue on the cable burial before full hand over to operator Scira Offshore Energy Ltd. (Norfolk, England). Statoil (Stavanger, Norway) and Statkraft (Oslo, Norway) own the wind farm via the joint venture company Scira, and Statoil has been the construction project manager.

Work on the termination of all the infield cables is now complete, and they are ready to transmit power once each turbine becomes operational.

The placement of scour protection around the foundation bases is in the final stages.

Subsea Vision Buys Saab Seaeye ROV
Subsea Vision (Corfe Mullen, England) has taken delivery of a Cougar XT Compact ROV, manufacturer Saab Seaeye (Fareham, England) said in June. Subsea Vision will be able to use the ROV to service FPSOs in the North Sea. The ROV will enable work for longer periods in strong tidal areas and allow Subsea Vision to offer larger tooling packages, such as pipe-tracking systems, and manipulator and hydraulic skids for light-class work operations.

Subsea Vision's Cougar XT Compact comes with dual fiber optics and a dedicated fiber-optic link for client-specific tooling. Saab Seaeye engineers created the compact version of the ROV by reducing the frame size, buoyancy and weight for a design with the highest thrust-to-weight ratio in its class, the company said.

ARA mobilized its ROV ROUMRS, which was fitted with a Sonardyne WSM 6 transponder. A Scout transceiver was deployed from the side of the dock on a pole. Positioning data from Scout was fed to Sonardyne ViewPoint navigation software.

Proteus Completes Red Sea Satellite-Based Bathymetric Mapping Project in 10 Days
Proteus (Abu Dhabi, United Arab Emirates) has completed a 200-square-kilometer bathymetric mapping project along the Red Sea coastline in 10 days, deriving the bathymetric data from DigitalGlobe (Arlington, Virginia) WorldView-2 high-resolution, eight-band satellite imagery.

The project could have taken six to eight months if the data had been collected by boat due to required government permits and shallow-water navigation obstacles, Proteus said.

The satellite bathymetry process extracted seafloor elevation measurements to depths of 20 meters with a 4-meter point density at distances up to 5 kilometers off the Saudi Arabian Coast. The bathymetric data supported an environmental assessment by Sogreah (Lyon, France) in preparation for construction of a power plant south of Jeddah, Saudi Arabia.
