South China Sea Field Redevelopment – Witness the Subsea Technology Evolution One field is in South China Sea with a water depth of about 330m. It was first developed with FPSO, subsea wells and the first electrical subsea pump in the industry, taking subsea processing a giant step forward. After producing for 12 years, it […]

Reactive Flex-Joint- a qualified and field proven solution for Wellhead fatigue challenges Awareness of lower available Wellhead fatigue life increases as the industry gains more knowledge through analysis and tests. Loads on Wellhead are affected by vessel movements transferred through Marine Riser and Blow Out Preventer. These loads cause cyclical bending moments and Wellhead fatigue […]

Creating efficient manufacturing requirements for subsea equipment The ability to produce oil and gas in the most cost-effective way will be an important going forward. To support this DNV GL have driven several standardization initiatives related to manufacturing og subsea equipment. One key initiative is a joint industry effort to prepare requirements for parts manufactured […]

Remote Operated Subsea Lifting Operations Operating equipment on offshore vessels from a remote location has been a well-debated topic for many years. For long, this was just a wild idea, but the later year’s focus on digitalization and the introduction of a stable high-speed 4G mobile network in the North Sea suddenly brought it within […]

Functional Safety in All-Electric Subsea Control Systems Objectives/Scope: This paper discusses a novel all-electric control system architecture that uses batteries instead of mechanical springs to provide the required energy for fail-safe valve actuation. To evaluate the reliability of the safety instrumented system, the functional safety principles are explored. Methods, Procedures, Process: The paper covers the […]

All-electric for barrier elements Subsea all-electric has been discussed for at least 25 years, but has not yet been implemented to an industrial scale for well barrier elements. With the introduction of subsea compression stations, the default control and actuation principle is all-electric. However, for the simpler control system used for well barrier elements, the […]

Freedom vehicle – The subsea transformer! The subsea industry is looking for more cost-effective methods of executing ROV-related activities. Today there are vehicles in the market supporting both remote- and autonomous operations, but clients are pushing for more intervention related capabilities to meet their needs. In addition to environmental friendly solutions, they want flexibility, autonomy, […]

The Transformation of Underwater Vehicles; key to reducing IRM costs Subsea Inspection Repair and Maintenance (IRM) services have traditionally been vessel-based, relying on Remotely Operated Vehicles (ROV) or Diver operations. The industry challenge to reduce costs is driving the development of new working practices, leveraging the latest in communications, system electrification and autonomous technologies to […]

Equinor – Marianne Bryhni Asla

Equinor Strategy for Underwater Intervention Drone (UID™) The Statoil Underwater Intervention Drone (UID™) strategy describes the future use of remotely operated, semi-autonomous and autonomous underwater vehicles for subsea operations. The impact for Statoil will be higher production efficiency (PE), lower operational expenditure (OPEX), lower HSE risk and lower carbon footprint for new and existing oil […]
