OCIMF-Compliant Single Point Mooring (SPM) System
A 12-strand double-braid nylon hawser engineered for offshore tanker offloading at single point mooring and CALM buoys. Both ends carry PU-coated metal protective sleeves, and inline buoyancy floats keep the line on the surface and clear of the seabed — all manufactured to OCIMF standards.
Representative specification for the main SPM hawser. End fittings, float spacing, length and certified documentation are configured per terminal.

The complete single point mooring package — hawser, tails and connecting hardware.
The primary mooring line between buoy and tanker — 12-strand nylon double braid with PU-coated end sleeves and inline buoyancy floats.
High-elongation mooring tails in 11 m or 22 m lengths with galvanised steel shackles — the compliant interface between hawser and vessel chain stopper.
