BMT said in a statement the riser tension monitoring systems would be installed between the riser top assembly and the buoyancy module.The systems will provide long-term monitoring of the buoyancy force that is used to stabilise the riser towers on the fields. BMT said it would also supply on-board communication and recording hardware and monitoring software. The company said the system will be the fourth using its proprietary subsea strain sensor assembly. It said the subsea sensor assembly on the latest system would be serviceable using a remotely operated vehicle. The company has significant experience in supplying similar deep-water systems for Petrobras’s P-52 platform off Brazil and the company’s Cascade-Chinook field in the Gulf of Mexico, as well as for BP’s Greater Plutonio project off Angola. OFFSHORE INTEGRITY MONITORING specialist BMT Scientific Marine Services said it would supply a tension monitoring system for two single leg risers on two deep-water floating production, storage and offloading vessels off West Africa under a deal with Italian engineering outfit Saipem.
