cutSOFEC_EBUOY_DETAIL_01_20231206As the need for electrical power for vessels at sea grows, SOFEC announced that ABS awarded the newly developed Electric Charging Buoy (ECB) an Approval in Principle (AiP). Traditional SOFEC CALM buoy designs have integrated electrical power cable management solutions that allow vessel(s) mooring while utilizing externally supplied power. By using this proven concept, SOFEC can leverage its buoy designs and modify them to accommodate offshore electric power transfer from seaports or offshore wind farms substations to Electric Vessels.

ClassNK awards AiPs for SDARI’s green fuels powered vehicle carriers for ammonia ready LNG dual fueled 7,000CEU, and both methanol/ammonia dual fueled 10,000CEUClassNK has issued Approvals in Principle (AiPs) for three vehicle carrier designs developed by Shanghai Merchant Ship Design & Research Institute (SDARI). The first AiP acknowledges an ammonia ready LNG dual fueled vehicle carrier with a capacity of 7,000 CEU, a significant first in China’s independently developed design.

DNV awarded an Approval in Principle (AiP) certificate to China Merchants Jinling Shipyard (Nanjing) Co., Ltd. for its 11,000-CEU capacity pure car and truck carrier (PCTC) design.Recognized as the world's largest PCTC, the 234m long and 40m wide ship will have 14 decks allowing 11,000 car equivalent units (CEUs) to be stored simultaneously, which not only increases efficiency but also reduces the transport cost per vehicle.By implementing a combination of decarbonization measures…

Erma First received Approval in Principle (AiP) from DNV for its amine absorption-based Onboard Carbon Capture (OCC) system, which was put to the test onboard a RoRo ship.The system uses amine absorption technology and a proprietary amine solvent to absorb CO2 from flue gases. When heated, the chemical reaction that occurs reverses the absorption and separates the CO2 from the solvent. The CO2 that is released is subsequently liquified and stored under cryogenic conditions onboard and the regenerated solvent can be re-used, creating a highly efficient regenerative OCC process.

Bureau Veritas (BV), the Shanghai Merchant Ship Design & Research Institute (SDARI) and NAPA have completed the first phase of a Joint Development Project (JDP) to enable 3D model-based approvals for the classification of ships. The project validated the feasibility of 3D model-based approvals where classification reviews are directly based on the 3D model provided by the designer, rather than requiring multiple conversions to 2D drawings, which is the traditional process. The objective is to boost efficiency in the design process…
