Offshore

Rig Barrier Net
These very large nets attach to the bow and stern columns on the starboard and portside of offshore drilling/production units.

Supply Vessel
Mooring System
When weather conditions are too bad to lay alongside a platform, supply boats tie up by the stern under the crane for loading and offloading.

Winch Lines
Traditional marine engineering holds that wire rope is the preferred line for use on winches.

Supply Vessel
Mooring System
All types of schemes with tires and ropes have been tried to prevent line breakage during rough weather. The problem is that the distance from the platform leg to the boat is too short. The Wishbone system creates a much longer line by utilizing the vertical distance between deck and the lower area of the platform

Wind, current and waves create forces on a moored vessel to surge back and forth. A mooring line must do two things: hold against the forces and stretch to accommodate the surge.

The stretch requirement is often overlooked due to focus on strength only. This system utilizes the strength and elasticity of synthetic fiber ropes to hold a supply boat on station. The elasticity compensates for vessel motion due to waves.
