Overview

Our range of subsea floatation collars enable acoustic navigation and positioning transponders to be deployed, moored on the seabed and then recovered to the surface.

The floats are compatible with all our transponders including: Compatt 6+, Compatt 6, AMT 6 and DPT 6. They can be used with directional and omni-directional transducer types.

Manufactured from high performance materials appropriate to the required depth rating, each float assembly comes in two halves and is clamped around the transponder using stainless steel fixings made of super duplex stainless steel.

Bright colours make sure good visibility, either when subsea and viewed from an ROV’s camera, or when floating on the surface prior to recovery.

At a glance

• Use it to recover seabed transponders without ROV intervention
• Choice of shapes to suit application and environment
• Available in 3,000, 5,000 and 7,000 metre depth ratings

We also supply ultra low-drag light bulb shaped float that provide significant reduction of the deflection caused by water currents and dramatically improves the stability of the transponder. The levels of both the deflection and stability directly affect the quality of the achievable positioning. The light bulb float therefore ensures optimum performance from the seabed installed transponders.

The ultra low-drag and highly stable float further allows users to deploy transponders much higher off the seabed increasing the achievable acoustic range. This reduces the required number of transponders enabling life of field positioning without requiring complicated deflection correction methods.
