Yaskawa Environmental Energy / The Switch shines a light on how to produce electricity efficiently on ships.A ship is like a floating city that needs electricity to power its operations and amenities on board. So how to generate that electricity while being mobile? That question has been challenging the shipping industry for more than 150 years, when exciting new technologies were being pioneered at the forefront of the new age of electricity. Fast forward to today, and the challenges surrounding the production of electricity on board vessels have been spurred again.

Finland-based power electronics specialist Yaskawa Environmental Energy/The Switch is partnering up with maritime energy storage system (ESS) manufacturer Corvus Energy to continue the development of its smart Battery Short-Circuit Limiter (BSCL) protection device for large-scale battery solutions and advanced DC power distribution.Under the three-year memorandum of understanding (MoU), Corvus Energy becomes the preferred partner for Yaskawa Environmental Energy / The Switch in the ongoing development of the.According to the companies…

Although LNG (Liquid Natural Gas) provides a solid supplement to European gas supplies, the EU is and will remain a pipeline market – for good reasons, said Wintershall's new position paper.The report from Germany's largest crude oil and natural gas producer on the importance of liquid gas for Europe said that the liquefaction is highly energy-intensive – the energy consumption corresponds to about 13% of the gas transported.With an energy loss of less than five percent, pipelines are much more energy-efficient. Another argument for pipeline gas lay in its lower costs. Russian pipeline gas, for example, is more competitive and less expensive than LNG from the USA.Since the EU's own gas production is declining, Wintershall welcomes any additional import route.

CMN Shipyard in Cherbourg, France, conducted sea trials on the June  13, 2018 on the OPV Thémis from the French Coastguard (Affaires Maritimes).The patrol vessel received a hydrodynamic upgrade at the shipyard by retrofitting the patented Hull Vane, an underwater wing which reduces the ship’s resistance. Comparison with the benchmark sea trials – conducted in January in exactly the same conditions – by CMN’s sea trial team showed a reduction in fuel consumption of 18 percent at 12 knots, 27 percent at 15 knots and 22 percent at 20 knots.

ABB’s newly launched Azipod propulsion unit is said to be up to 10 percent more efficient than previous versions. ABB hopes to expand the appeal of the podded electric propulsion system beyond established markets with its improved efficiency and bollard pull. According to ABB, the new linear flow Azipod XL achieves this jump in efficiency by introducing a nozzle with stator plates, which directs the water flow from the propeller to reduce the turbulence and energy loss and to give the optimum thrust for the vessel.

Russia has built a giant military base in the far northern Arctic where 150 soldiers can live autonomously for up to 18 months, AFP quotes the Defence Ministry as saying. The building erected on the large island of Alexandra Land, which is part of the Franz Josef Land archipelago, is 97 percent complete. The "Arctic Trefoil" compound, located on 80th parallel north has been built using the latest technologies to prevent energy loss. The construction teams have paved the roads on the remote island and the main building is 97 percent complete, according to the officials. The soldiers can move around the base from one building to another without going outside to face winter temperatures which can reach minus 47 degrees Celsius (-57 degrees Fahrenheit). Fuel can be pumped in from tankers.

Last month Hydrex installed Propeller Boss Cap Fins (PBCF) on a 289-meter tanker during the vessel’s stop in Mokpo, South Korea. A Propeller Boss Cap Fins (PBCF) can recover energy loss of a propeller hub vortex in the propeller’s backward flow. This decreases fuel consumption by 5% when operating at the same speed, or boosts speed by 2% with the same fuel consumption. A clear explanation of the benefits of installing a PBCF can be found here. By performing the operation on-site and underwater, the tanker’s owner could immediately benefit from the system’s fuel savings.

Alaska Marine Lines, a Lynden company providing marine transportation to and from Alaska, is continuing its efforts to work lean and green by purchasing 200 of the most energy efficient refrigerated units in the world. The Star Cool "reefers" achieve the industry's lowest energy consumption by matching the compressor speed to the required heat load of the container rather than running at a single constant speed. In addition, the box and refrigeration equipment are built as one unit with an insulation system designed to minimize energy loss.

Last month Hydrex installed  Propeller Boss Cap Fins (PBCF) on two tankers during their respective stops in Ghent and Antwerp. As a result of the underwater operation, the ships will not have to wait for their next drydock visit to start benefitting from the fuel savings the PBCF’s will bring them. The Propeller Boss Cap Fins (PBCF) is a device for propeller efficiency improvement developed by Mitsui O. S. K. Lines, Ltd. The PBCF can recover energy loss of a propeller hub vortex in the propeller’s backward flow.

Shell U.K. Exploration and Production said the final cost of a four-year project to decommission its controversial Brent Spar oil buoy had risen sharply. At a feedback seminar marking the effective completion of Brent Spar's conversion into a quay on the Norwegian coast, Shell officials also said that instead of resulting in a projected net gain in energy the project resulted in a net energy deficit. "Throughout the dismantling process we were faced with unexpected technical, safety and environmental challenges which had to be overcome and each one cost time and money," Eric Faulds, Decommissioning Manager for Shell's exploration and production arm Shell Expro said.
