Leidschendam, the Netherlands -- ONGC has commissioned pipeline inspection services offshore Mumbai from Fugro Survey (India).
The $6.2-million contract involves acoustic inspection of 5,400 km (3,355 mi) of subsea pipelines in this area off India’s west coast, including trunk lines and infield lines. Work will be performed between mid-September and March 2011.
Fugro Survey will deploy a multibeam echosounder, side scan sonar, a pinger profile, and the Starfix DGPS system to aid accurate mapping of the various lines during the program’s initial phase. Thereafter, it will bring in a remotely operated towed vehicle to inspect the trunklines in more detail, with an ROV performing detailed inspection of “critical” pipe sections.
The company will mobilize itsFlambouyan survey vessel for the project. According to Fugro, ONG conducts this type of survey at regular five-year intervals.
