DNV GL and Aker BP carried out safety inspections on three offshore cranes on the Norwegian continental shelf. The pilot inspections were part of Aker BP’s strategy to minimize its corporate carbon footprint.
As part of annual inspections, DNV GL carried out the inspections of a box jib crane on the Valhall Flank West and two knuckle cranes on the Skarv field. Crane operators and specialist crane technicians aboard the platforms used tablets to capture close-up videos and pictures. A checklist with safety functions was created, which was used jointly by the onshore inspectors of DNV GL.
The inspection on the normally unmanned Valhall Flank West platform included the initial inspection of a 1 year old crane: autotest of the automatic overload protection system, structural connections, critical hydraulic and electrical components, manual overload protection system and brakes.
A similar inspection program is carried out on two kingpin cranes on the floating production storage and unloading unit (FPSO) in the Skarv field.
The ongoing remote assistance pilot task, anchored in 350-450m of water and 210km off the coast of Sandnessjøen, Norway, will remotely assess how important safety tasks can be performed without the trust, safety of staff and the At risk asset in this process.
This approach also cuts costs by eliminating the need to travel to Brønnøysund and Skarv, and allows DNV GL experts to connect remotely as well.
“The use of an automatic test system with a digital interface significantly reduces the risk compared to manual inspections via procedures,” said Svein Harald Hetland, Technical Authority at Aker BP. “The next generation of cranes will be equipped with continuous monitoring systems that will enable us to introduce a predictive maintenance regime. The remote inspection programs then focus on checking the entire systems. “
Ine Dolve, Aker BP’s senior vice president of operations and asset development, added that his company’s operating model will leverage the lessons learned from the pilot and that the remote assist approach will scale across all assets.
DNV GL performed more than 4,000 remote inspections for the oil and gas industry in 2020 to respond to the strong demand for virtual verification and certification services for topside and underwater equipment, including a ship warranty investigation of a barge and platform in Senegal and material certification of underwater equipment in China.
