New Test Rig for 'Next Generation' Mooring Connectors


Subsea mooring connector (SMC) specialist, First Subsea invested more than $300,000 in new mooring connector test rig facilities at its production site in Lancaster, UK.

The test-rig is being used in the manufacture of 'next generation' SMCs for industry leading, deepwater mooring projects: the Jack & St Malo field's semi-submersible platform and Lucius field's Spar moorings, both in the Gulf of Mexico.

The SMC test rig is used for proof load and Minimum Breaking Load (MBL) testing up to 2,600mT (25,497 kN).

'Next Generation' Mooring Connectors
First Subsea, in collaboration with the University of Sheffield's Institute for Microstructural and Mechanical Process Engineering (IMMPETUS), has systematically improved the performance of its mooring connectors. The metals forging research is now being applied to the manufacture of the company's latest Ballgrab Series III male connectors - the largest produced so far with an un-corroded 2,599mT (25,491kN) MBL, and compliant with the ABS Mooring Guide 2009.

"This is a significant investment that will ensure our Ballgrab subsea mooring connector continues to set the standard for deepwater moorings," says John Shaw, managing director, First Subsea Ltd.
