Norway: Statoil and Aker Solutions Get ONS Award

Gas compression is one of the most important measures Statoil employs to deliver volumes from existing fields on the Norwegian shelf. ONS is awarding the prize to Statoil and Aker Solutions, who together nominated Åsgard subsea gas compression.

The award was announced , Wednesday, 29 August, in connection with ONS 2012 in Stavanger.

Åsgard subsea gas compression is one of Statoil’s most demanding technology projects aimed at improved recovery.

“We are pleased and proud to win this prize. With this technology in place, we can achieve significant improvement in both recovery rates and lifetimes for several gas fields. From Mikkel and Midgard on the Åsgard field, recovery is increased by 280 million barrels of oil equivalents,” says technology director Siri Espedal Kindem.

Technological leap

Subsea processing, particularly gas compression, is an important technology for developing fields in deep water in vulnerable areas. Åsgard subsea gas compression brings us one step closer to realising our goal of a subsea factory.

A subsea factory is a processing facility on the seabed, which makes it possible to remotely control transport of hydrocarbons.

Ensures high gas stream

Åsgard subsea gas compression will contribute to maintaining the production level for the Midgard and Mikkel gas reservoirs on the Åsgard field.

The two reservoirs are developed with seabed installations, and the wellstream is sent in a joint pipeline to the Åsgard B platform, 50 and 70 kilometres away, respectively.

Analyses indicate that, towards the end of 2015, pressure in the reservoirs will be too low to avoid unstable flow and maintain a high production profile to Åsgard B. Compression provides the necessary force to ensure a high gas stream and recovery rate.

Energy-efficient

A large seabed structure with two compressors, pumps, scrubbers and coolers will be placed on the seabed, near the Midgard wellheads.

On Åsgard, dry gas compressors will be used. Gas and liquids will be separated before the gas is compressed. Afterwards, gas-liquid and gas will be blended in the same pipeline prior to transport to Åsgard B.

“The closer compression takes place to the well, the higher the effect and production rate. Performing compression on the seabed also gives us advantages in the form of better energy efficiency,” explains Espedal Kindem.

FPSO Europe Congress

 

Pursuing Cost-Optimization & Project Excellence across Europe’s FPSO Value Chain!

Launched to great success in 2015, the FPSO Europe Congress is set to return on 24-25 February 2016 in London for yet another exciting gathering of Europe’s leading oil operators, FPSO contractors, EPCs, shipyards and solution providers to discuss the most topical and critical FPSO developments in the North Sea, Latin America, Brazil and West Africa market.

 

Why Attend the 2nd Annual FPSO Europe Congress?

  • Discover how FPSO leaders are embracing the new realities of a low oil price environment – what are the strategies to adopt in pursuit of viable economical FPSO projects?
  • Brainstorm with industry experts on innovative FPSO engineering, construction and technology breakthroughs leading to significant CAPEX and OPEX savings
  • Review, refine and optimize your existing FPSO operations – how can we enhance oil recovery and extend FPSO asset lifetime?
  • Learn from FPSO experts on the ins-and-outs of delivering successful FSPO projects in North Sea, West Africa, Latin America and Brazil – how can we comply with local content and form effective native partnerships?
  • Engage and form sustainable partnerships with European-based oil companies and FPSO contractors that are leading offshore E&P and FPSO projects in the region

 

2016 FPSO Distinguished Speakers Include:

  • Curtis Lohr, Stones Project Manager, Shell
  • David Hartell, Senior Development Manager, Premier Oil
  • Terry Hughes, Project Director, Tullow Oil
  • Sid Sircar, Facilities Delivery Manager – Catcher Development, Premier Oil
  • Michael Wyllie, Group Technology Director, SBM Offshore
  • Chris Brett, President, Teekay Offshore
  • Puneet Sharma, Vice President, MODEC

Substructures for UK Offshore Wind

Design, construction and installation

Optimising offshore substructures is one of the key challenges for reducing LCOE. Foundation designers have produced a variety of different solutions: monopiles, GBS, jackets, suction buckets and floating foundations. Looking at U.K. projects – different soils, water depths,fabrication timelines and installation challengescreate many questions for the industry to solve. We’re entering uncharted territory; projects arelarger, farther and more complex than ever completed.

Now is the time to have a close look at lessons learnt and define the room for improvement for the U.K. wind industry.
