Dutch-built Workboat

Six Wärtsilä diesel gen-sets provide the backbone of the power plant for a new rigid reeled pipelay/offshore construction vessel that was recently launched in the Netherlands by Merwede Shipyard.

The 157 m long vessel, which was designed for a complement of 120 crew, will be called Seven Oceans and was built for Subsea 7, a leading subsea engineering and construction contractor under a contract placed in June 2005. Merwede

Shipyard is part of the IHC Holland Merwede BV group of companies.

The power plant will consist of six Wärtsilä 7L32 diesel gen-sets totaling 21 MW of power and driving a 6. 6 kV integrated electric power system. The propulsion of the vessel is provided by three electromotor-driven, fixed-pitch propellers in type FS-3000-SL/WN aft azimuthing thrusters.

Two retractable azimuth thrusters, type FS-2510/MNR, will be fitted in the forward part of the vessel and one transverse thruster, type FT300H-D, will be arranged in a tunnel forward. All thrusters will be delivered by Wärtsilä, Merwede said.

The vessel, which is due to be delivered in spring 2007, has a pipe-laying capability with a top tension of 400 tons and a storage capacity of 3500 tons of rigid steel on the main reel. It will also have a 400 ton deepwater crane, a built-in deepwater remotely operated vehicle and a survey system. A

Couple differently! Two things are the most important for design engineers. Easy to build and a high-strength connection. Voith Hirth couplings do exactly this, especially at high torques. Our Hirth couplings have these features: form fitting, part precision, and reproducibility. A series of advantages that really count in your application.

Voith Hirth couplings are used in machine tools, in compressor construction, in measurement engineering, robot engineering, nuclear technology and medicine technology.
