Mooring

First Subsea has developed a new range of mooring line jewellery that includes forged metal H-links and crossed H-links, and fabricated Pear / Plate links for subsea mooring lines. The crossed H-link is designed specifically to eliminate the need for mooring line shackles.
 

Drawing on its metals forging research, First Subsea has designed the H-links to make it easier and quicker to handle chain-to-chain and chain to Ballgrab mooring connector links.
 

The updated the H-link design bring it into line with the demands of today's mooring projects for efficient mooring connections offshore. The forged H-links are well-designed with a bevelled pin retention locking mechanism that reduces the risk of snagging as it goes over the stern roller. They are also a more durable alternative to rolled plate H-links.

Crossed H-link replaces shackles
 

The crossed H-link is intended to replace shackles in the mooring line. First Subsea's growing knowledge of the metals forging process has allowed it to optimise the H-link's forging conditions. It combines the strength of a H-link with the flexible movement of a shackle.
 

Pear / Plate link improved fabrication
 

The First Subsea Pear or Plate link is lighter and more robust than traditional plate links. Used for rope-to-rope and rope-to-chain connections, the link is fabricated such that it is capable of withstanding the rigours of the stern roller without splitting.
