Deep, ultra-deepwater capex
to continue growing to 2017
Infeld Systems’ ninth Global Perspectives Deep and Ultra-deepwater Market Report to 2017 sees capex in those depths to grow
over the next fve years.
The forecast is for water depths of 500 m ( 1,640 ft) and more.
Demand is pushing exploration further offshore into harsher
and deeper waters, says Infeld. Deepwater reserve additions are
expected to remain a marginal proportion of overall global production; rising from a 7% cumulative share of global reserves in 2012 to
10% by 2017. In capex terms, the deepwater market, which requires
higher capital expenditure than its shallow water counterparts, is
expected to rise from a 38% share in 2012 to a 53% share of global
offshore capex by 2017.
Even with attention centered on the “Deepwater Triangle” of Brazil, West Africa, and the Gulf of Mexico, Infeld sees support coming from less traditional deepwater arenas such as Southeast Asia,
Australasia, and Europe. Substantial growth is also predicted for the
Middle East and Caspian.
Brazil is expected to lead the deepwater market with spending on
the Lula and Franco developments.
The GoM deepwater action will be led by Shell, with a 24% market
share of capex including the ultra-deepwater development at Stones
While West Africa will continue to lead the continent, deepwater
activity is expected to increase offshore East Africa, particularly the
Prosperidade complex offshore Mozambique.
The key felds expected to go on production through 2017 offshore Asia, include Liwan off China, Shell’s Gumusut-Kakap off
Malaysia, and Chevron’s Gendalo-Genhem
offshore Indonesia. New developments

cals, six jumpers, two fowlines with two steel catenary risers, two subsea pump modules, and topsides support equipment. Production
will fow through two 10-in. production fowlines with subsea single-phase boost pumps.
Julia is 265 mi (426 km) southwest of New Orleans in the Walker
Ridge area in water depths of approximately 7,000 ft ( 2,134 m).
McDermott will undertake engineering, procurement, and construction of the jumpers, four suction piles associated with the manifold, subsea pump, pump transformer, and subsea distribution unit/
umbilical termination assembly (SDU/UTA), as well as transportation and installation of the manifold, suction piles, fying leads, subsea
pump system, the power and control umbilicals, and SDU/UTAs.
McDermott will also carry out testing of the tieback system and
mechanical completion before hand over to the customer.
McDermott deepwater installation vessel Derrick Barge 50 is expected to install the suction piles and subsea equipment, including
the manifold, pump station, and transformer. The vessel’s new deepwater lowering system has the capability to lower loads of up to 480
tons to depths of up to 11,500 ft ( 3,505 m).
In addition, North Ocean 102 is scheduled to transport and install
umbilicals, fying leads, and jumpers. NO102 is a fast-transit vessel
with horizontal carousel. Recent improvements include installation
of a high-capacity fexible-lay system to enable ultra-deepwater installation work – comprising a 330-ton top-tension fex-lay tower,
with 275-ton active heave compensation crane and 330-ton hang-off
clamp capable of lowering loads to a depth of 10,000 ft ( 3,048 m).
The offshore installation is expected to begin in 2Q 2015 and extend through 2015.

Aker Solutions wins
its largest-ever UK
Aker Solutions has won a contract worth
up to $440 million to deliver subsea production system for an oil feld in the UK North
The delivery includes 25 subsea trees,
six template manifolds, and associated
controls, wellheads and tie-in equipment.
“This is the single-largest subsea contract
that we’ve won in the UK,” said Alan Brun-nen, head of Aker Solutions’ subsea business.
The order includes technologies new to
the UK, including manifolds and trees that
can enable the use of hydraulically submersible pumps to improve oil recovery
and fow assurance. Aker will also provide
diverless horizontal tie-in systems and
slim line rigid lockdown wellheads.
Aker, at Fornebu in Nor way, will handle
central management, engineering, and procurement for the project. The company’s
Tranby facility outside of Oslo will manufacture the subsea trees, while production of
the manifolds and system integration testing will be at the company’s offshore yard
in Egersund on the west coast of Norway.
Aker Solutions’ subsea operations in Aberdeen will manufacture the control systems
and wellheads. It will also provide lifecycle-support services.
The frst deliveries are scheduled for the
frst half of 2014. Aker Solutions has withheld
the name of the feld and the operator. •
