FlexLink™ umbilical buoyancy

FlexLink was developed to meet the needs of large, tracked, trenching vehicles that operate on the sea bed.


To prevent such vehicles damaging their control lines, FlexLink is installed at the tether point to provide a continuous, articulate buoyant section above the vehicle, thereby ensuring the umbilical remains out of the vehicle work zone at all times.

FlexLink is used as a permanent installation which is designed to pass through the sheave wheels of launch and recovery systems (LARS). It is supplied for installation onto umbilicals ranging in size 25-75mm OD while the buoyancy can be specified to suit project requirements.

Typical uplift ranges from 6-12kg/m in design operating depths of 0-6000msw.
