We have a large press for making wire rope swage fitting terminations and a hydraulic load testing device for testing.

We routinely splice 8-strand plaited ropes and 12-strand spectra ropes for the multitude of mooring and pop-up buoy applications.

Mooring Rigging

We perform complete pre-assembly of a surface buoy S-tether mooring.

This application allowed deployment of the mooring directly into the water from the box secured on the ship deck.

Sediment Trap Bridles

We manufacture upper sediment trap rope bridles with no metal components, or stronger wire rope bridles, and heavy lower chain bridles for trap stability during deployment and recovery.

We stock the standard sizes for use in most oceanographic instrument mooring applications.

Our Anchors are assembled using 900 lb. locomotive train wheels.

Assemblies can be customized for any number of wheels to obtain the desired ballast weight.

Center posts are provided with a pinned pear link for connecting to the mooring chain.

Specialized Components

Mooring Systems supplies bronze wire rope clamps for CTD and other instrument casts.
