Oil Removed from WWII Era Shipwreck

A U.S. Navy led team has removed 229,000 gallons of oil from a sunken World War II era German heavy cruiser that has been resting on the seafloor near the Marshall Islands for more than 70 years.After being transferred to the U.S. as a war prize, the cruiser Prinz Eugen was loaded with oil and cargo and used to assess survivability of warships during the Operation Crossroads atomic bomb tests in the Pacific. The ship survived two atomic blasts before being towed to Kwajalein Atoll, where it capsized and sunk in December 1946.Now, 72 years later, a project team led by Stephanie Bocek of the Navy's

While floating wind turbines aim to limit the response to wave loads, wave energy converters, for example

The exploration and production of deepwater pre-salt plays offshore Brazil have triggered major technological challenges. Some reservoirs are located under 2,000 meters of water and have to be drilled through another 2,000 or so meters of salt. Although exploration challenges have been daunting, production challenges are no less formidable. With a number of production and injection wells placed over the large reservoirs, the difficulty of reliably and safely bringing the oil and gas to production FPSOs have been compounded by the extreme water depths involved.In 2011 Subsea 7 was awarded a milestone

Almarin Buoys Reach New Markets

Almarin navigation buoys are being installed in a growing number of markets both in Europe and further afield, proving the effectiveness of their simple reliable design with the use of high quality materials manufactured in Europe.   In the Léman lake, border between France and Switzerland, buoys have been installed to mark a floating containment boom in the estuary of Rhone river, nearby Port Valais. The Balizamar buoys used in this case were adapted by the customer for this application.   Further east, in an estuary in Beirut (Lebanon), several buoys have been supplied complete

Sustainable Marine Energy’s Inshore Platform PLAT-I Powers Up

On November 25th Edinburgh-based tidal energy technology developer Sustainable Marine Energy (SME) completed the installation of its game changing PLAT-I tidal energy system at Connel, near Oban in western Scotland.   The operation, including tow-out, was completed in under 5 hours using Green Marine’s multicat vessel Green Isle. PLAT-I is a multiple turbine floating tidal energy platform hosting Schottel Hydro's (SHY) turbine system rated at 280kW. The power take-off system comprises four Schottel Instream Turbines (SIT) and an accessible power conversion system hosted in an on-board

SBM Offshore Wins Johan Castberg Turret Mooring System Contract

SBM Offshore said it was awarded the contract and received the corresponding notice from Statoil to proceed with the engineering, procurement, construction (EPC) work scope for a large-scale turret mooring system for its Johan Castberg development.    The contract award results from delivery of the front-end engineering and design (FEED) scope for the mooring system delivered in cooperation between Statoil and SBM Offshore teams.   The turret is planned to be delivered in modules in early 2020, will be moored in c. 370 meter water depth and will have a capacity to accommodate 21
