GN is a DNV, ABS and BV approved manufacturer for mooring chain accessories. Our inhouse engineering department is able to design the right connector, FEA strength, Fatigue calculation, Classification design approvals, and a complete product certificate for use of this products in the mooring lines.

Shackles are mainly used on chain end links and can be made in all sizes to give the best fit connection. Forged H-links can be special designed to fit common links and other connection points. Plate connectors are mainly designed to connect chain to rope or rope to rope. LTM Sockets are Forged and used on steel wire rope.

For special designs which are not in accordance with ISO1704, Classification design approval must be considered for full certification!

instructions for use

All mooring connectors must be proof load tested, 1 of every 25 pieces or heat treatment batch must be breakload tested. All mooring connectors must be 100% MPI and US inspected. Mechanical testing every heat treatment batch or 1 of every 25 pieces. Mechanical testing must be performed on a real size product, test specimens are not allowed by the classification bureaus. DNV and BV allows to do the mechanical test out of a break loaded shackle, however ABS require to do this from a proof loaded shackle. 

Standard impact test is carried out at -20 degrees Celsius. On request we can inform you about low temperature impact values, such as -40, -50 and -60 degrees Celsius.
