Lifetime Reliable Clamping

The Subsea Clamping Cylinder for fully automatic Bend Stiffener Connectors (BSCs) is designed for use for up to 25 years and is impressive with its high clamping forces, powerless holding operation, and easy installation with no need for manual work by divers. The patented automation solution withstands forces of up to 120 tons per clamping cylinder. A proven cushioning mechanism absorbs vibrations and distributes the load across a number of cylinders within the system. This prevents material fatigue and premature wear with a predefined clamping force. The integrated clamping unit allows straightforward, reliable actuation during commissioning and removal–even after long periods of use.

While the rated force is being set hydraulically, a spring in the cylinder is tensioned and fixed using a safety lock unit. This allows the clamping force to be maintained over the entire operating time in a purely mechanical manner, with no need for a continuous hydraulic or electrical power supply. 

A further advantage: the robust design of the Subsea Clamping Cylinders takes into account the entire usage cycle. Until the system is installed, it can be stored underwater at a depth of up to 3,000 m for a period of two years. The clamping unit can be hydraulically released and controlled easily, safely, and reliably for removal or for further use.

The Subsea Clamping Cylinders can be used in numerous different clamping applications–not just in a marine or offshore setting but on land too.
