Korean Register (KR) has signed a Memorandum of Understanding (MoU) with HD Hyundai Heavy Industries (HD HHI), UK-based wind propulsion technology company BAR Technologies and the Liberian International Ship & Corporate Registry (LISCR) to jointly develop a 174K LNG carrier equipped with the WindWings wind-assisted propulsion system.
The project will focus on an LNG carrier developed by HD HHI with a forward accommodation arrangement. Positioning the crew accommodation block towards the bow provides additional space on the upper deck for the integration of BAR Technologies’ WindWings system.
WindWings uses large, rigid wing sails installed on a vessel to harness wind as supplementary propulsion.
Under the agreement, HD HHI will lead the vessel’s basic design and design review. BAR Technologies will provide technical data on the arrangement and specifications of WindWings, structural strength, operational concepts and expected fuel savings.
KR and LISCR will assess the safety and technical suitability of the design against applicable rules and international requirements. Based on the assessment, KR will also consider granting Approval in Principle (AiP) for the design.
