Norway to Power Offshore Platforms from Land?

The operators and licence holders for the Johan Sverdrup, Dagny, Draupne and Luno fields in the North Sea will study setting up a hub for the supply of electrical power from land. The study will form the basis for a decision on electrification.

The study, which has been initiated by the Ministry of Petroleum and Energy, is headed by Statoil and involves the operators Lundin and Det norske oljeselskap, as well as the other licence holders. The work will comprise technical studies, such as concept planning, as well as commercial solutions for the electrification of the fields on the Utsira High. The intention is to create a framework for potentially setting up a company or partnership to own and operate the facilities that will feed the receiving platforms with power.

It is primarily the gigantic Johan Sverdrup discovery – together with Luno, Draupne and Dagny, including Eirin – that makes such a shared power solution possible. Preparations will be made for the possible subsequent tie-in of other installations on the Norwegian continental shelf.

The study will take in an offshore distribution platform located near Johan Sverdrup, with DC cables from land to the distribution platform and AC cables on to the receiving platforms. An analysis of the power situation at the potential land-based connection points will also form part of the study.

There will be the additional requirement for converters and transformers on the distribution platform and on land. AC cables will also be necessary and the existing switching station will need to be extended for connection to the grid network.

The progress plan for study will, to a large extent, be governed by the plans of those who will be in receipt of the power.

A concept will be selected, and the investment decision made,at the earliest in the fourth quarter of this year.

The decision to electrify will be taken by the licence holders/owners, on the basis of profitability, the official specifications and the conditions stipulated . Utsira Height can be well suited for electrification due to its considerable power needs, as well as the favourable distances and water depths involved.

USA: BMT to Provide Simulation Services for Production Platforms Towing

image

Hereema Marine Contractors Nederland B.V Inc. (“HMC”) has awarded a contract to BMT Fluid Mechanics in partnership with BMT ARGOSS, to provide Tow Simulation Services for the inshore tow of Chevron-operated Jack St. Malo and Big Foot Production Platforms to be installed in the Gulf of Mexico.

BMT will be engineering, procuring, installing and commissioning a purpose built simulation facility to be located in Houston, Texas, for the purpose of training tug captains and other marine personnel involved with the inshore towing of the platforms from the Ingleside integration yards. The inshore tows are particularly challenging because of the extremely small hull clearances within the shipping channels leading from the yards out to the gulf. Up to five independently controlled tug boats will be effectively, rigidly coupled to the hull to perform the 15 mile wet-tows.

BMT’s PC Rembrandt real time maneuvering training software will be the basis of the simulator. The simulator will provide a realistic hands-on facility for tug captains to develop safe operating strategies for the tow and develop rational weather and tide operating limits.

USA: Technip Wins 10-Year Master Contract From BP for Spar Platforms

image

Technip was awarded a 10-year master agreement by BP Exploration and Production, Inc. The agreement covers the design, procurement and construction of hulls and mooring systems for Spar(1) platforms to be located in the Gulf of Mexico, as well as the design of top tension risers(2) for dry tree units.

This award follows a design competition and confirms Technip’s leadership in Spar technology, secured over time through the construction of 14 of the 17 existing Spars worldwide.

Technip’s operating center in Houston, Texas, will execute the agreement. It stipulates that the Spars will be fabricated at the Group’s yard in Pori, Finland, where 12 of Technip’s 14 Spars have already been manufactured.

Within the framework of this agreement, pre-front-end engineering design activity for the Mad Dog Phase II Spar has already begun. The front-end engineering design for this project is scheduled to commence in the second semester of 2011.
