Total lowers Carbon Footprint with Power from Shore
End of March, the Norwegian Government approved the development plan for the Martin Linge oil and gas field.
Total capital expenditure is estimated to $4.2 billion with the expectation of recoverable reserves in the field estimated at 189 million barrels of oil equivalents (BOE).
The proposition will now be sent to the Storting, Norway’s national assembly.
The field will be developed with an installation resting on the seabed.
The processed gas will be exported to St Fergus in the UK via a new link to the existing Frigg UK Pipeline (FUKA).
The oil, water and condensates will be processed and stored on a dedicated storage vessel where water is separated for reinjection, and oil will be exported via shuttle tankers.
In order to reduce the carbon footprint of the Norwegian shelf, Total has decided to power Martin Linge offshore facilities from shore from Kollsnes.
Total and its partners Petoro and Statoil strive to minimize Martin Linde environmental footprint as part of its concern for sustainable development.
Therefore they select to power Martin Linge Offshore needs from the Norwegian mainland electrical grid via a new 170 kilometres long subsea cable, the world’s longest alternating current (AC) power line from shore to an offshore platform.
This technical solution is in line with the Norwegian authorities’ longstanding objective to curb CO2 emissions from offshore activities.
The subsea cable will also incorporate optic fibre links allowing the offshore facilities to be remotely monitored and controlled from Total’s operation centre in Stavanger.
Martin Linge challenges call Total for innovation
Although the Norwegian government approved the development of the Total operated Martin Linge field, the Norwegian Petroleum Safety Agency (NPS) warned that the French oil major‘s current well design is “not robust enough” against the reservoir’s high pressure and high temperature.
The PSA‘s warning comes as Total is battling a natural gas leak at the a high-pressure, high-temperature Elgin field, offshore Scotland.
The PSA also said Total hadn’t paid enough attention to the flow volume if it loses well control during drilling, according to government documents.
Total said it took these remarks seriously, and said that it is in talks with the authority and planning to improve the Martin Linge well design.
Drilling wells should not start before the summer of 2014, it gives time to Total to follow this through.
The untapped Martin Linge natural gas field was discovered in 1978 and is estimated to contain 189 million barrels of oil equivalent (BOE).
Aker Solutions completes Feasibility Study and FEED
The contract value is about NOK 215 million.
Aker Solutions‘ scope of work includes engineering for several building blocks:
– FSO (floating storage and offloading for oil, water and condensates)
– Turret and mooring
– SURF (subsea umbilicals, risers, pipelines and flowlines)
– Transportation and installation.
The topside engineering will be done from Aker Solutions‘ head offices in Oslo, Norway, while the turret and mooring work will be conducted in Kristiansand, Norway.
FEED work is scheduled for completion in the summer of 2012.
Total awarded the Jacket EPC contract to Kvaerner
Feb. 2012 – Total has awarded Kvaerner an EPSC-contract for the delivery of a steel jacket for $210 million
The contract includes engineering, procurement, supply, construction, load-out and sea-fastening of the jacket and associated piles.
The jacket is scheduled for completion and delivery in 2014.
Global competition for the Deck EPC Contract
For the deck package, the South Korean Contractors (Hyundai Heavy Industries, Daewoo Shipbuilding & Marine Engineering, Samsung Heavy Industries) are very active.
But the Norwegian yard Kvaerner Stord and Aibel, the Singapore’s SMOED, the Spanish Dragados Offshore and the Dutch Heerema are reported also in the competition.
Topsides split in three packages to facilitate lifting
Total and Aker Solutions designed the Topsides in three packages in order to lift them one by one on the supporting jacket and assemble them with an heavy lifting vessel.
– 9000 t module for the Processing and Drilling deck
– 9000 t module for the Utilities
– 2000 t module for the living quarter
To facilitate the connection between the modules, Total is expecting to award the two large modules to the same shipyard while the living quarter could be executed separately.
FSO may be new built or converted unit
The FSO should be Aframax type with capacity to store between 500,000 and 700,000 barrels.
But Total is still comparing costs and time frame between a new built unit or a converted one estimated around $100 million.
– Teekay Navion Shuttle Tankers Offshore (TNSTO) based in Stavanger, Norway.
– Tanker Pacific from Singapore.
– Knutsen from Haugesund, Norway.
The Norwegian TNSTO and Knutsen propose a converted FSO, while Tanker Pacific goes with a new-build FSO from Samsung Heavy Industries.
Production at Martin Linge is expected to peak at 100,000 boe per day.
Total and its partners planned oil and gas production start for the Martin Linge oil and gas field is fourth quarter 2016, and the production period is expected to last for 11 years.
