Single Point Mooring Experience Secures ABS Class for More Buoys

H

aving classed the first offshore LNG deepwater port buoy for Excelerate’s Energy Bridge Deepwater Port in the Gulf of Mexico, ABS has class contracts on four more buoys: two for Excelerate’s Northeast Gateway project and two for Woodside Natural Gas Inc.’s OceanWay Secure Energy.

 The buoys are the STL design, a type of single-point mooring system, from Advanced Production and Loading AS of Norway (APL). See earlier Energy News article ABS TO CLASS FIRST OFFSHORE LNG DEEPWATER PORT BUOY for background.

The Excelerate Energy's Northeast Gateway deepwater liquefied natural gas (LNG) port has a projected mid-2007 in-service date and is located offshore Massachusetts. As with the previous Excelerate project, ABS will class the buoy to include: technical review of the STL buoy and associated moorings, riser and PLEM for site-specific location in accordance with ABS Rules for Building and Classing Single Point Moorings as well survey of the STL buoy during construction, offshore installation of the piles, moorings, PLEM and STL buoy together with gas riser.

Australia’s Woodside Natural Gas Inc.’s project offshore California will use the same technology and transport system for its LNG project.

APL’s Submerged Turret Loading (STL) Buoy System for LNG Imports was honored for Emerging Innovation/ Technology. The STL received classification from ABS and it became the first offshore LNG deepwater port buoy. No longer considered an “emerging technology” the STL buoy system is now a proven gas transport system with others on order for LNG projects off the East and West Coasts of the United States.

A similar technology to APL’s STL buoy design is its Submerged Turret Production (STP) flexible turret mooring system for floating production and offloading vessels (FPSOs). ABS will provide class for this APL STP mooring system to be used on the Maari FPSO for Sydney-based Horizon Oil with installation slated for 2008. The Maari FPSO will be located offshore New Zealand. ABS will conduct the same scope of technical services on this mooring system in order for it to achieve class.
