Floating Wind and the Taming of Subsea Spaghetti
Preparing for industrialization, the floating offshore wind industry is tackling its unique mooring and cabling challenges.The idea of keeping floating offshore wind platforms in place using dynamic positioning has been considered. The trouble is: it could take up to 80% of the electricity generated by the turbine to do it.So, as Maersk Supply Service said a few years back: In a field of 100 turbines with 4-5 mooring lines each, there is going to be a lot of subsea “spaghetti.” It’s not a problem unique to the industry…
Offshore Charging Station Tested on Hybrid Construction Vessel
Norwegian lifting and handling specialist Seaonics has tested its Ocean Charger solution on an electric service operation vessel (SOV).High-voltage charging tests were conducted to charge the batteries on Rem Offshore’s diesel-electric hybrid construction SOV, REM Power, in port as well offshore from a charging point (cable reel, winch and control system) mounted on a wind turbine."At 10 years old, the turbine is one of the smallest offshore but the prototype proved it is possible to install the Ocean Charger on an existing turbine and charge an SOV from day one…

Updates, Developments and Advances in Combat and Patrol Craft
My first visit in 2007 to the American Society of Naval Engineers’ (ASNE) Multi-Agency Craft Conference (MACC) was an eye-opener. Having built a naval architecture career with frigates, destroyers and other large naval and commercial ships, I was eager to learn of the smaller craft used by the U.S. Navy and other government and military bodies. As my flight into Norfolk, Va. descended over Chesapeake Bay, I gazed in amazement as a Landing Craft Air Cushion (LCAC) raced toward Virginia Beach, slowed, glided up the beach and into its shore base.
