Crux liquids object of review

Crux field is in Production License AC/L9 in the Browse basin, offshore Western Australia. It was acquired by Nexus in January 2006, and Nexus is operator with 85% equity in the liquids Osaka Gas has the remaining 15%.

Shell Development Australia holds the rights to 100% of the gas resource within the permit and under the current contract can access the gas in 2021. Average water depth is around 170 m (558 ft) with the major reservoir at 3,800 m (12,467 ft).

Petrobras contracts $1 billion in subsea work

Subsea 7 S.A. has won work from Petrobras totaling about $1 billion for the development of the pre-salt deepwater Guará and Lula NE areas in the Santos basin, offshore Brazil, in water depths of approximately 2,200 m (7,218 ft).

The project scope includes the engineering, procurement, installation, and pre-commissioning of four decoupled riser systems featuring:

• Four submerged buoys each of 1,900 m tons (2,094 tons) to be installed at approximately 250 m (820 ft) below the sea level buoy foundations and associated tethers
• 27 steel catenary risers of 3.9 km (2.4 mi) and associated pipeline end terminations of which 18 7.5-in. production lines, three 9.5-in. water injection lines, six 8-in. gas injection lines, and associated anchor piles and crossings.

Engineering and project management are under way in Rio de Janeiro. Fabrication of the rigid pipelines will be at the pipeline fabrication spoolbase that Subsea 7 is developing at Paranaguá, Paraná in Brazil. Offshore installation is scheduled during the second half of 2012, using Seven Oceans, Seven Seas and Skandi Seven.

Statoil moves to standardize workover systems, maintenance

Statoil has exercised three options with Aker Solutions for delivery of workover systems, or equipment for well completion and maintenance. These options have a total value of approximately NOK 1.25 billion ($223.7 million).

The options are based on the award of the contract for Vigdis North East to Aker Solutions in the 1Q 2011 and work under the contract begins immediately.

The installation systems will be used primarily on the Troll and Gullfaks fields and on the company’s fasttrack projects. Deliveries are expected in the course of autumn 2012 and spring 2013.

Statoil set new requirements for multi-functionality of installation systems so that the same system can be used regardless of which supplier is chosen to deliver the seabed infrastructure. This move will provide simplified logistics and standardized equipment to improve the efficiency.

“The use of this type of universal system means that we will boost completion and maintenance capacity. It also represents a necessary renewal of our toolbox systems,” says Siri Kindem, head of Technology Excellence in Statoil. “In close cooperation with our suppliers we have developed solutions that are at the forefront: technologically, operationally, and in terms of safety.”

Statoil says industrialization and standardization on the Norwegian continental shelf are the keys to reduce time and cost.

“In order to boost added value on the NCS and achieve our production targets, we are totally dependent on using smarter solutions and reducing the costs of drilling and well operations. We will be seeing more of this type of solutions in the future,” says Øystein Arvid Håland, head of Drilling and Wells in Statoil.

ROV demand spurs sales

Schilling Robotics, LLC says C-Innovation has contracted for multiple ROV systems in support of expanding international operations. This contract includes the supply of both HD and UHD work class ROVs.

Ricardo Chagas, president of C-Innovation said “the global deepwater market continues to be a focus for C-Innovation’s growth strategy, and we are delighted to continue with the expansion of our ROV fleet services by adding a versatile range of vehicle systems to meet our increasing customer requirements.”

Chagas also stated “the global subsea industry will experience significant growth in upcoming years, and C-Innovation is prepared to support customer operations on a global basis with the world’s most modern fleet of vessels and ROVs.”

RESON has sold two SeaBat 7125ROV2 systems to Ashtead Technology in Aberdeen, UK. The 2011 year model SeaBat 7125ROV2 system is the latest in the SeaBat 7125 series. The data quality, system reliability, and new feature sets distinguish the SeaBat.

Offshore Technology Solutions Ltd. has ordered a Saab Seaeye Panther XT Plus electric ROV.

The configuration chosen by OTSL includes a Seaeye wide-angle black and white low-light camera and a Kongsberg color zoom camera together with pan and tilt system; a Tritech Super SeaKing sonar; five and six function heavy duty manipulator with grabber; a water jetting system; and a Cygnus ultrasonic thickness gauge with CP contact probe, BlueView imaging sonar, and state-of- the-art Visual Soft DVR and inspection software.

List finds 300 major subsea projects

Subsea UK has made available to members its databases on subsea projects, contracts, and new discoveries.

The entire database accounts for more than 300 major on-going or up-coming subsea projects globally, which will require more than 1,300 subsea trees, 110 manifolds, and 12,000 km of subsea umbilicals, risers, and flowlines. These include 70 projects in the UKCS, as well as those in Norway, Brazil, West Africa, Australia, Asia-Pacific, and the Gulf of Mexico.

This contracts data says that more than 100 major subsea projects valued at £4.5 billion ($7.3 billion) were awarded in the first four months of 2011. Among the projects are 23 EPIC, 33 manufacturing, and 13 installation contracts.
