Harvey Gulf International Marine has chosen the American Bureau of Shipping (ABS) to class two Offshore Supply Vessels (OSV) being retrofitted with a dual fuel as well as battery system. The Harvey Energy will become the first US-flagged OSV equipped with a battery/converter system.
ABS published a report, providing an introduction to air lubrication technology for shipbuilders, shipowners, and other interested parties. In the paper, ABS presents a summary of reported full-scale sea trials and current developments. Air lubrication systems are recognized by IMO as a Category B-1 “Innovative Energy Efficiency Technology” as described in MEPC.1/Circ.815.
Rolls-Royce received Approval in Principle (AIP) from ABS for its hybrid propulsion system for tractor tugs. The AIP was granted after evaluating the world’s first hybrid tug, which will be the first tug boat installed with the Rolls-Royce hybrid propulsion system.
ABS, OceanFinance and Scorpius Space Launch Company will collaborate on the SPACE TECH4SEA project to adapt technologies developed for the space industry to LNG shipping. The project aims to apply composite technology as an alternative in LNG as marine fuel designs.
The design basis is storing 2 Mbbl of crude oil in the barge-shaped hull, applying mainly shipbuilding standards, and combining offshore production facility features, such as a 25-year lifetime without drydocking, and structural reinforcement for Topside structure installation.
ABS granted two Approvals in Principle to Dalian Shipbuilding Industry Co., Ltd. for its Self-Elevating Unit Design, and its Tension Leg Platform design for the offshore industry.
The new VLEC will incorporate a specialized membrane cargo containment system, which will carry liquid gas cargoes like ethane and propane. The vessel was designed with a minimum cargo temperature of -94℃, supporting a low cargo boil-off rate.
ABS has published a guide on the ‘Use of Supercapacitors in the Marine and Offshore Industries’ to support safe application of hybrid power in the marine and offshore industries. The guide outlines the types of supercapacitors, including electrochemical capacitors and lithium ion capacitors.
ABS classification society announced that it has issued a managed pressure drilling notation to Seadrill’s West Capella ultra-deep water drillship, demonstrating system compliance with the ABS Guide for Classification and Certification of Managed Pressure Drilling Systems.
ABS approved the design and certified the GMS cantilever system for its self-elevating support vessel GMS Evolution, delivered in May 2017. As an industry first, GMS Evolution is fitted with a small removable skidding cantilever system, installed with a well ‘work over unit’.
