Comments
This single product CALM is installed in 28m water depth. The ADMA-OPCO CALM features a double hull design that eliminates potential repair problems associated with foam filled compart-ments. Six 3.75-in. chain legs anchor the 12.5m diameter CALM.
The fluid swivel incorporates an electrical swivel, which relays SCADA signals to the internal accumulator powered hydraulic valve control system that permits the PLEM valves to be remotely operated. The CALM is equipped with a load monitoring system and dual 20-in. double carcass hoses.
