SUBSEA TECHNOLOGIES & OPPORTUNTITES

SUBSEA BUSNINESS TRENDS •

Subsea portfolio is expected to double within the next 5 years

•

Increasing contribution from subsea volumes

•

Field locations remote from infrastructure

Production by Resource Type

SUBSEA INDUSTRY The subsea industry is involved in extracting oil and gas reserves which lie beneath the seabed, but also covers other sectors such as •

Oceanology,

•

Marine renewables and

•

Defence.

OPPORTUNTIES Survey operations: Specialist technologies used to image, map and examine seabed condition Excavation and trenching: Pipelines and umbilicals are buried below the seabed to protect them from damage by currents etc., Flowline assurance: Examines how different oil behaves as it moves through a pipeline to help improve the flow. Separation and processing: Separate oil, gas and water beneath the surface and processed.

Inspection: ROVs and AUVs, often with specialised electronic equipment to take detailed images or readings. Subsea control systems: Monitoring of all underwater equipment such as Christmas trees, manifolds and valves etc., Corrosion management: ROVs and intelligent pigging to assess to avoid leakages or structural failure. SUBSEA TECHNOLOGIES

SUBSEA EQUIPMENT ROV: Remotely Operated Vehicles (ROVs) are used to access difficult to reach locations in the sea. AUV: Pre-programmed and piloted by an onboard computer. Christmas tree: This vital piece of subsea equipment is placed above the well on the seabed to control the flow of oil or gas. Pigs: For the purposes of moving or separating fluids, cleaning or inspection is called ‘pigging’. Dynamic positioning, deepwater positioning: To keep a vessel in a stationary position over a subsea oil well or construction site using thrusters or propellers on the vessel.

Umbilicals: Umbilicals are enclosed bundles of cables and pipes housing a combination of electrical, hydraulic, chemical or fibre optic connections to link the surface and underwater equipment. Flexible riser: A tube or pipe carrying oil, gas or water to the surface. The riser is flexible to allow it to move with the motion of the sea without breaking Pumps and compressors: Pumps and compressors build up pressure to push oil and gas through underwater pipelines or to the surface.

•

The subsea industry has met its challenges over the years with some catastrophes but many successes

•

Considerable R&D spend on subsea technology

•

Greater emphasis on testing before full field implementation

•

Reliability Standards being set – Structured Approach

•

Incorporation of lessons learnt

•

Improve Quality Management to ensure second and third tier suppliers testing / documentation traceability is visible

•

Standardisation is key to cost containment and reliability
