ABS granted approval in principle (AIP) for a Tension Leg Platform (DSTLP500) design developed by Dalian Shipbuilding Industry Co., Ltd. (DSIC). “ABS and DSIC have a long relationship and have worked closely on a broad range of offshore projects, semi-submersible units, jackups and drill ships,” said ABS Executive Vice President for Global Offshore Kenneth Richardson. “Gaining ABS approval is an important step in helping bring this project closer to realization,” said Wenmin Liu, China Ship Design Master and Senior Offshore Technical Expert DSIC. This unit is designed with four pontoons, four columns and eight tendons, suitable for operation in the water depth up to 500m, primarily in South China Sea.

“As the energy mix shifts and global demand for gas increases, concepts like this will reshape how energy is supplied,” said ABS Vice President for Global Gas Solutions, Patrick Janssens. This concept offers a new approach to delivering new sources of power to remote areas of the world. The conceptual design is based on existing LNG carriers which are converted into floating power plants with small (~72 MW) to medium (~400 MW) scale power generation capabilities. In reviewing Chiyoda’s floating LNG power plant concept, ABS said it applied its relevant Rules and Guides to confirm that the conceptual design meets the intent of applicable class requirements.

Conrad Shipyard and The Shearer Group, Inc. (TSGI) said that its design of a 4,200 horsepower LNG-powered towboat received “Approval in Principle” (AIP) from the American Bureau of Shipping (ABS). The boat is based on TSGI’s azimuth drive (Z-drive) towboat design that debuted in 2008 as the FRANK T. STEGBAUER. To date, eight of these towboats have been built for Southern Towing Company, which is a pioneer in the use of z-drives for brown water operations. The boats have shown significant fuel savings relative to conventional towboats.

EBDG’s LNG bunkering barge design receives ABS approvals as the maritime industry increasingly looks to LNG as a fuel of the future. In early June, Federal Maritime Commissioner William P. Doyle told listeners at an LNG Bunkering conference in Vancouver, Canada that “Liquefied Natural Gas (LNG) bunkering in North America is moving forward … There is an abundant supply of natural gas in North America. Utilizing natural gas as a marine fuel would help ship owners and operators comply with the MARPOL Annex VI requirements to reduce air pollution from ocean going vessels.” That much is true. It’s also true that there is any number of ways for vessel operators to get to the Promised Land. Nevertheless, LNG – as a fuel – has certainly stepped out into the lead on that mission.

Approval in principle confirms Onboard DC Grid’s suitability for marine application. The new system supports the growth of electrical propulsion systems onboard ships. ABB, a power and automation technology group, was granted Approval in Principal (AIP) for the Onboard DCGrid power distribution system by classification society American Bureau of Shipping (ABS). To be granted the AIP, the Onboard DC Grid was subject to a series of risk assessment techniques to determine if the concept provides acceptable levels of safety in line with current marine industry practice, requirements and standards. The AIP now granted by ABS is a strong tool to support and streamline the design, approval, execution and inspection of new projects.
