marinerenewables Pelamis WEC Moves Closer To Commercialization Tank testing of scale models to develop the next generation of Pelamis Wave Power's (Edinburgh, Scotland) wave energy converter (WEC) machines have been successfully completed. The tank testing process forms a key part of a £1.4 million project commissioned and funded by the Energy Technologies Institute (ETI), which is looking to boost the cost-effectiveness of large-scale WEC arrays in U.K. waters. The two 29th-scale Pelamis P2e models featured a number of potential improvements to the current Pelamis P2, such as larger and elliptically shaped tubes, different numbers of joints and tube lengths, and enhanced control systems. The tank testing allowed for the most extreme storm conditions to be applied over extended periods of time. The testing was undertaken over one month in a wave basin at the École Centrale de Nantes in France. The Kongsberg to Deliver Vessel Control For Wind Turbine Jack-Up models were exposed to the full-scale equivalent of 50 hours of extreme storms, with waves up to 23 meters high. These results drive the engineering design program and provide robust evidence for verifcation purposes. In the tank tests, new control algorithms showed an increase of 100 percent more power capture in small and medium seas than those previously implemented. This demonstrates huge potential reduction in the cost of energy from Pelamis technology achievable through software upgrades alone. The P2e design is larger, more powerful, and developed for volume production and long-term reliability. These improvements are intended to satisfy the demand for commercial-scale wave farms currently being developed in Scottish waters and beyond. The new P2e design, now moving into the detailed design phase, builds on the successful demonstration of two P2 machines in Orkney at the European Marine Energy Centre. Nordic Yards in Wismar, Germany, has awarded Kongsberg Maritime (Kongsberg, Norway) a contract to deliver an Integrated Vessel Control System for a new build 80-meter wind turbine service jack-up vessel, owned by DBB Jack-Up (Aarhus, Denmark). The integrated full-picture solution covers navigation, automation and maneuvering systems, and will be one of the frst to feature Kongsberg Maritime's recently launched LAN-based radar system. The new radar concept, K-Bridge composite picture radar CP360, is an integral part of the K-Bridge navigation system to be installed. With new, user-friendly control of radar video and tracking, CP360 distributes digital radar signals on a local area network (LAN). This makes possible combining radar images from multiple radar transceivers and displaying them as a single composite picture, eliminating blind sectors and providing a single 360-degree view, covering different ranges, around the vessel. The complete delivery to DBB Jack-Up's new vessel includes K-Chief Hydrographic Training Event January 13-16, 2014 Mobile, AL Join us for our 21st HYPACK¨ Hydrographic Training Event, HYPACK 2014.
