LLOG Exploration Co. LLC has signed an agreement with FMC Technologies Inc. to design, manufacture, and supply subsea production equipment to support the Who Dat project in the Gulf of Mexico. The $40-million contract covers the supply of seven subsea production trees and control systems and deliveries are expected to begin in 2012.

Shell has contracted Subsea 7 for two engineering and installation contracts for Cardamom and West Boreas in the Gulf of Mexico.

At West Boreas, Subsea 7 will install a 6,096-m (20,000 ft) long umbilical and subsea distribution hardware in water depth to 959 m (3,146 ft) in Mississippi Canyon.

At Cardamom, Subsea 7 will install a 9,266-m (30,400 ft) long umbilical plus subsea distribution hardware in water depths to 914 m (2,999 ft) in Garden Banks.

Subsea 7'sSkandi Neptune construction vessel will be used at both jobs.

EMAS says that its subsea construction division,EMAS AMC, has been awarded a contract by BP Exploration & Production to perform subsea work in the Atlantis field, in Green Canyon block 743 in the Gulf of Mexico.

The project scope consists of the installation and replacement of subsea equipment comprised of manifolds, PLEMs (pipeline end manifolds), jumpers and associated hardware in 6,800 ft (2,073 m) of water, as well as assisting BP with complete commissioning and start-up activities.

EMAS AMC's regional headquarters in Houston will execute the planning and installation activities for the BP project during the first half of 2012.

Subsea Systems

Chevron Australia Pty Ltd has contracted FMC Technologies Inc. to design, manufacture, and supply subsea production systems for the Wheatstone Project offshore Australia.

The $325-million contract includes 11 subsea production trees, 11 wellheads, three manifolds, subsea and topside controls, and well access systems. Delivery is scheduled to begin in 2013.

The Chevron-operated Wheatstone Project comprises the Wheatstone and Iago gas fields offshore Western Australia in water depths between 330 and 850 ft (100 to 260 m).

Anadarko Petroleum Corp. and FMC Technologies Inc. have signed a global alliance agreement covering subsea systems and life-of-field services.

"An alliance has been in place with Anadarko and its legacy companies since 1992 to support their Gulf of Mexico exploration and production projects," said John Gremp, FMC Technologies' chairman, president and CEO.

"Today's announcement will allow FMC to broaden its support of Anadarko's expanding exploration and production activities worldwide, including recent discoveries offshore the East and West coasts of Africa. Anadarko has an extensive deepwater program, and we are pleased to strengthen our relationship through this global alliance."

Statoil has awarded Aker Solutions a NOK 225-million ($38-million) contract for engineering, procurement, and construction of a subsea production system for Vilje South on the Norwegian continental shelf.

Aker will supply a subsea tree, satellite production flowbase and protection structure, subsea production controls, well, remote connections, and a 150-m (492 ft) long static umbilical. Final deliveries are scheduled for 2Q 2013.

Vilje South is a fasttrack oil field in the middle part of the North Sea, about 20 km (12 mi) northeast of Alvheim and just north of the Heimdal field in a water depth of approximately 120 m (395 ft).

Lundin Norway has awarded Aker Subsea a NOK-700 million ($123.9 million) EPC contract for a subsea production system for the Brynhild project in the Norwegian North Sea.

The scope of work includes one template-manifold structure, one riser base, three subsea trees, three wellhead systems, a control system, a tie-in system, 38 km (23.6 mi) of umbilicals, an HP riser, and rental tooling.

There are also options for additional equipment, including other field developments.

Brynhild is northwest of the Ula field and 38 km (24 mi) east of the Pierce in UK waters, in 80-m (262 ft) water depth. It will be developed as a fasttrack subsea tieback to thePierce FPSO.

Engineering and procurement of the subsea production system will be conducted mainly at Aker Solutions' headquarters in Oslo.

Fabrication of the subsea trees will be completed at Aker Solutions' manufacturing center in Tranby, Norway, while the company's yard in Egersund will handle the template-manifolds.

The umbilical will be manufactured in Moss, Norway, and the control and wellhead systems in Aberdeen, UK.

Aker Solution's service base in Aagotnes, Norway, will handle the installations, with final deliveries scheduled for spring 2013.

Subsea 7 SA has announced award of a $200-million SURF (subsea umbilical riser and flowline) contract from Petróleo Brasileiro.

The Campos basin project, 80 km (50 mi) offshore Brazil, includes management, engineering, procurement, and installation of two 34-in. OD rigid oil lines 4.5 km (2.8 mi) long in 70-m (230 ft) water depth, plus umbilicals and related subsea equipment.

The subsea layout is an offshore terminal for temporary oil storage, an offloading unit, and two mono-buoys connected to the subsea system through flexible hoses and umbilicals.

Engineering and project management begin immediately with offshore operations due to commence in the first half of 2013 using a number of Subsea 7's pipelay and construction vessels.

Participants are: Woodside Energy (operator 16.67%); BHP Billiton Petroleum (North West Shelf) (16.67%); BP Developments Australia (16.67%); Chevron Australia (16.67%); Japan Australia LNG (MIMI) (16.67%); and Shell Development (Australia) (16.67%).

Anadarko has contracted Metocean Services International (MSI) for a two-year multiple location metocean measurement project offshore Mozambique in preparation to develop deepwater natural gas discoveries in the offshore Rovuma basin.

The metocean data-gathering program is designed to measure wind, wave, current, water/air temperature, tides, and so on. Once processed, this environmental data should assist offshore, coastal, and onshore operations for the entire project.

MSI will undertake seven shallow and seven deep moorings, in water depths ranging from 6-2,000 m (19.7-6,561 ft). The seven shallow moorings include Nortek acoustic wave and current meters (AWACs) and RBR CTD loggers with turbidity sensors. Six of the seven deep sites will be short in-line moorings fitted with TRDI acoustic Doppler current profilers (ADCPs) and RBR CTD loggers with turbidity sensors.

The deepest site is a full water column mooring comprising Nortek AWAC, Nortek Aquadopp single-point current meters, RBR CTD logger with turbidity sensor, and TRDI ADCP.

ROV market to grow through 2015

Spending on ROV support of underwater operations is expected to grow from $891 million in 2010 to $1,692 million in 2015, according to the latest report from Douglas-Westwood.

"Although ROVs are today used in many sectors ranging from academic research to military applications and salvage, the largest commercial user is the offshore oil and gas industry where they have become an essential tool for deepwater operations," said John Westwood, chairman of Douglas-Westwood. "This was clearly demonstrated recently in the subsea work to cap the Macondo blow-out in the US Gulf of Mexico.

"Despite continuing turmoil in financial markets, in 2011 it seems that the offshore oil and gas industry is facing a future of significant growth and in the longer term we still have the full impact of Brazil's major presalt deepwater developments to come. In addition, new, albeit much smaller, markets are emerging in sectors such as the offshore wind. The future looks good for the ROV industry."
