Pipe Handling

Caley Ocean Systems recognises the importance of secure and accurate clamping during pipe laying operations. Our pipe clamping system is based on a proven and highly successful friction clamps design originally developed for deepwater J laying of steel rigid pipe.

Proven friction clamp technology

Capable of handling loads in excess of 1,200Te

Accurate PLC control integrated with the pipelay vessel’s SCADA (Supervisory Control and Data Acquisition) system.

The clamp system’s completely bolted construction allows greater flexibility during clamping, which can be either opened or split to accommodate pipe and collar arrangements.

Flexible Pipelay Deployment

The head clamp, typically 500 T, is an open design and features a hang off collar as well as the friction clamp. The workstation clamp, on the other hand, has a split design and can also handle collar and pipe up to 750 T. The collar clamp can be operated independently.

As the final holding device on a pipe laying vessel, the Caley workstation pipe clamp is built to the highest possible integrity. It comprises a specially designed cylinder with an integral, high integrity, manifold fitted with zero leakage valves, allowing the cylinder to withstand lateral loads as well as axial loads.

In the event that the workstation clamp has to support a flooded pipe, Caley’s unique leak free valve system is able to hold the load for at least 24 hours, even with a total loss of power.
