Technip takes several contracts
Within the last few weeks, Technip has won contracts for work in the Gulf of Mexico, offshore Ghana, and in the North Sea.
In the GoM, Technip has a lump-sum contract from ENI US Operating to tieback the Appaloosa well to the Corral platform. Appaloosa is in Mississippi Canyon, 145 nautical mi (268 km) offshore Mobile, Alabama, at a water depth of 2,825 ft (860 m).
The contract covers project management and surveys; engineering, fabrication, and installation of a 21-mi long (34-km) production flowline; a riser and subsea equipment; installation of umbilical and flying leads; and pre-commissioning and dewatering of the flowline.
Technip’s operating center in Houston will execute this contract. The flowline and riser will be welded at the Group’s spoolbase in Mobile, Alabama.
Earlier, Technip landed a lump-sum contract from BP Exploration and Production Co. for a GoM subsea tieback from Isabela to the Na Kika semisubmersible platform in Mississippi Canyon, 140 mi (225 km) offshore New Orleans at a water depth of 6,300 ft (1,920 m).
That contract covers project management and engineering, fabrication, and installation of pipe-in-pipe flowlines, steel catenary risers, and subsea equipment.
Technip in Houston and the spoolbase in Mobile will handle the work. Offshore installation is scheduled to be completed in 3Q 2010.
Off Norway in the North Sea, Eni Norge AS has awarded Technip a €200 million ($300 million) engineering, procurement, construction, and installation contract for Goliat. Goliat will be the first Norwegian oil producing field north of the Arctic Circle in the Barents Sea.
The lump-sum contract includes supply and installation of the infield pipeline systems, including flexible risers, clad production flowlines complete with direct heating systems, and water and gas injection flowlines, and also installation of the provided subsea production system including umbilicals, templates, and riser bases.
Offshore installation is scheduled over three construction seasons from 2011 to 2013.
Lastly, Tullow Ghana Ltd. has awarded Technip two lump-sum contracts for the development of the Jubilee oil field off Ghana in 1,200 to 1,700 m (3,937 to 5,577 ft) water depths.
The first contract covers engineering and fabrication of seven 10-in. (25-cm) diameter and two 8-in. (20-cm) diameter risers with a total length exceeding 27 km (16 ¾ mi). Engineering will be done by Technip’s operating center in Paris, with the risers fabricated in Le Trait, France. Delivery is scheduled for early 2010.
The second contract covers engineering, fabrication, and installation of approximately 48 km (30 mi) of production and gas and water injection rigid flowlines; installation of 26 km (16 mi) of umbilicals, nine flexible risers, and subsea manifold and riser base structures; connection of the flowlines to the wellheads and subsea manifolds; and system tests.
Technip Houston will execute this contract with support from Paris for the installation of the flexible flowlines, the connections and offshore operations. The offshore campaign is scheduled to commence in early 2010 using theDeep Blue and the Deep Pioneer.
Petrobras orders high-capacity, multi-phase pumps
Petrobras and Framo Engineering have signed an agreement to install a submarine multiphase pumping system in Campos basin off Brazil. The prototype will be the first installed helico-axial pump with a differential pressure above 60 kgf/cu m (5.88 MPa).
The pumps are expected to be installed in the second half of 2011 in the Barracuda field, and to operate in a satellite well of platformP-48 in 1,040 m (3,412 ft).
Cameron counts largest-ever order for multi-phase pumps
Cameron will install 16 multi-phase pump systems on three Pemex platforms in the Gulf of Mexico for $86-million; Cameron says this marks its largest-ever such order.
The systems are destined for the KuMaloobZaap field in the GoM.
Cameron will engineer and package the systems using Leistritz Co. multiphase pumps to boost pipeline delivery pressure and to increase the oil production rate. Installation is expected in 2011.
KuMaloobZaap is offshore Tabasco and Campeche in 100 m (328 ft) of water.
Shell awards $200-million contract for subsea development off Nigeria
Shell Nigeria Exploration and Production Co. Ltd. has awarded a $200-million contract to Saipem for subsea work at Bonga-North-West field 120 km (75 mi) offshore.
The contract covers engineering, procurement, fabrication, installation and pre-commissioning of 13 km (8 mi) of 10-in./12-in. (25.5-cm/30.5-cm) pipe-in-pipe flowlines, 4 km (2.5 mi) of 12-in. (30.5 cm) water injection lines, plus installation of 15 km (9 mi) of umbilicals
Bonga North-West is in 900 to 1,200 m (2,953 to 3,937 ft) water depth. Installation work is scheduled between 3Q 2012 and 4Q 2013.
Buoyancy modules reach new depths
The drive to deeper water means more innovations. The first drilling risers buoyancy module that can go to 11,000 ft (3,350 m) water depth and handle the 5,000 psi (34.5 MPa) pressure is being manufactured by Trelleborg Offshore for Transocean to use on itsDhirubhai Deepwater KG1.
The buoyancy modules are made of low-density composite syntactic foam and macrospheres encased in an external skin that includes Trelleborg’s module integrity system.
