DNV Confirms Energy Efficiency Gains for LNG Carries with DFE+ Propulsion
New Dual Fuel, Electric+ (DFE+) concept, developed by ABB and MAN Energy Solutions, has been recognized by DNV as a more energy efficient alternative to current conventional designs for liquefied natural gas (LNG) carriers.DNV has quantified the gains that owners of LNG carriers could expect to achieve using the new DFE+ solution and found that it could help LNG carriers boost energy efficiency by up to 7.5%, therefore enabling greater emissions reduction.The number takes into account the smaller machinery space requirements with ‘a conservative estimate’ of 5% greater cargo capacity…
DNV Verifies Signal Ocean Platform's Vessel Emissions Estimates
The algorithm underpinning Signal Ocean's estimates of vessel CO2 emissions has been verified as meeting IMO guidelines by the independent classification society DNV.The calculation considers all aspects of any voyage as well as any route deviations already taken by any given available vessel. Other factors include the vessel’s size, age, speed, loading conditions, shipyard, use of scrubbers and the type of fuel used are also considered and represented in the algorithm's output.
CMM, HHI, Wärtsila, DNV GL Reveals LPGreen
In connection with the Gastech 2017 conference and exhibition in Tokyo, project partners Consolidated Marine Management (CMM), Hyundai Heavy Industries (HHI), Wärtsilä Oil & Gas, and DNV GL presented the results of a joint industry project (JIP) to develop a new LPG fuelled carrier design – LPGreen. Launched at the Posidonia trade fair in 2016, the JIP sought to develop a more energy efficient, environmentally friendly, and safer vessel for the transportation of LPG products. “In order to increase the competitiveness of modern LPG carriers, novel ship designs need to simultaneously account for the market and trade route characteristics…
DNV GL Works with Industry Leaders to Develop a New LPG Carrier
DNV GL has initiated a joint industry project for the design of a state-of-the-art next generation LPG carrier. LPGreen aims is to develop a more energy efficient, environmentally friendly, and safer vessel for the transportation of LPG products, taking into account existing and future trading patterns and ensuring the overall competitiveness of the concept. The project will incorporate the latest advances in hull form optimisation, cargo handling systems, engine technology and fuelling options. The resulting concept design will be compliant with the new IGC Code. DNV GL has brought together experts from across the industry for this project…
DNV GL Introduces Energy Efficiency Methodology
DNV GL presents a novel approach that overcomes challenges of assessing on board energy efficiency in a consistent manner. As a result, priorities for improvement can be determined accurately. In a new report released, DNV GL answers the question: How can a ship manager identify the biggest sources of useful energy that are currently being wasted on their ships? “Ship operations and environmental legislation have become more complex, and it has become increasingly difficult to assess or even define efficiency with consistency and accuracy…
