At SMM, DNV GL presented Hyundai Heavy Industries (HHI) and United Arab Shipping Company (UASC) with an Approval in Principle (AIP), recognizing the technical feasibility of the LNG fuel system design for the A14 and A18 series of container vessels.
The series of eleven 14,500 teu and six 18,800 teu containerships are under construction at HHI and HSHI for UASC and classed by DNV GL. These 17 vessels are intended to be converted to operate using LNG as ship fuel and the AIP has been prepared as part of DNV GL’s ‘LNG Ready’ service – demonstrating that the designs will enable a cost and time efficient conversion for LNG fuel operation. As part of the LNG Ready service, DNV GL has also cooperated with UASC to prepare the business case for the LNG fuel option.
The presentation of the AIP marks the culmination of an intensive development process, whereby HHI and UASC, supported by design and consulting bureau Technology Services and DNV GL, have worked closely together. During the pre-contract phase DNV GL’s Maritime Advisory unit had also been involved in order to assess the performance and to optimize the hull lines of the designs to minimize fuel consumption and air emissions for the expected operating profile.
During the design phase, extensive structural analysis was carried out, applying criteria that exceed normal class standards, based on UASC’s specifications. As well as being ready for an easy LNG retrofit, the vessels will fulfil the latest environmental requirements related to EEDI/EEOI, IHM and ballast water treatment as documented by the CLEAN class notation. In addition, WHRS (Waste Heat Recovery System) and shaft generator/motor have been applied to the vessels in order to achieve upmost fuel efficiency and reduce greenhouse gas emissions.
