Ancillary products and services

Umbilical floats
These floats comprise a pair of symmetrical half shells which are profiled to permit the line to flex within its specified bend radius.

Each float is manufactured using a low densitycomposite foam core covered in a high performance impact and abrasion resistant polyethylene shell.

The floats are hinged using two stainless steel latches and are designed to grip the umbilical by means of a natural rubber internal grommet.

Generally supplied in sizes from 25-150mm OD, the buoyancy can be specified to suit project requirements. Typical uplift ranges from 12-35kg per float in design operating depths of 0-6000msw.
 

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

To prevent these 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).

Flexlink is supplied for installation onto umbilicals ranging in size 25-150mm 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.
