Subsea 7 has contracted BMT Scientific Marine Services (BMT) to provide riser monitoring systems for two Hybrid Riser Towers (HRT) and one Single Hybrid Riser (SHR) for the CLOV Development Project offshore Angola operated by Total E&P Angola.
These systems will monitor the integrity of the risers by measuring the buoyancy uplift and bending fatigue, as well as each riser’s motions and set-down due to lateral excursions. Each system will include the BMT Subsea Strain Sensor Assembly; subsea data acquisition, motion and depth modules; and a rack-mounted display with BMT’s WinMon software for riser monitoring systems. Data transmission will be via a hard-wired link to the FPSO. The system will be designed for 21 years subsea service.
BMT brings valuable experience to this project having supplied a Free Standing Hybrid Riser Tower tension, motion and position monitoring system for Petrobras’s P-52 platform offshore Brazil, a Hybrid Riser Tower Monitoring System for BP’s Greater Plutonio Block 18 and a comprehensive integrity monitoring system for the Cascade & Chinook Free Standing Hybrid Risers (FSHRs) and Disconnectable Turret Buoy. The company is also currently in the process of providing a Riser Tower Monitoring System to two single leg offset risers offshore West Africa for SAIPEM and an Integrity Monitoring System for four risers in the Usan Field Development Project for TOTAL E&P Nigeria Limited.
