ABS issues AIP for LNG carrier

ABS has issued an Approval in Principle (AiP) for an LNG carrier design from Jiangnan Shipyard. The LNG JUMBO design features a WINGD X-DF low-pressure, low-speed two-stroke dual-fuel main engine propulsion system with enhanced propulsion efficiency and reduced fuel consumption. In gas mode, the system meets the IMO’s NOx Tier III requirements without the need...

Green Corridor project delivers LNG-fuelled bulk carrier designs

The Green Corridor Joint Industry Project (JIP) has delivered a Newcastlemax iron ore and coal carrier powered by liquefied natural gas (LNG) as part of phase 1a of the project and upsized it to a very large ore carrier (VLOC) in phase 1b. The purpose of the Green Corridor project is to develop an LNG-fuelled...

The human impact on autonomous ships

Autonomous technologies could create a competitive advantage for shipping companies, but adoption will vary significantly between market segments. This was the conclusion from a major piece of research carried out by the IMarEST Maritime Autonomous Surface Ships Special Interest Group (MASS-SIG). The research looked at the potential impact of self-governing ships and how this might...

ABS and Crowley pilot 3D modelling to assist with vessel design

A joint project by ABS and Crowley Maritime Corporation’s Jensen Maritime has resulted in time savings of 15-25 per cent in vessel design review, a process undertaken by classification societies. Using 3D computer-aided design (CAD), the project initially focussed on tug and barge designs. A 3D model was integrated into ABS’ classification processes, eliminating the...

New project examines feasibility of hydrogen-powered vessel

Sandia National Laboratories is leading a ship design and feasibility study that explores the use of hydrogen fuel cells to power vessels. The project team has designed a research vessel, known as Zero-V, to test hydrogen fuel cells. The vessel will operate at slow speeds for long distances, carrying few people and operating in voyaging...
