Woodside signs Subsea 7
for subsea construction
Woodside Energy has contracted Subsea 7 to perform
the Persephone work pack 2 fabrication, subsea installation, and diving services project offshore Western Australia.
The Persephone development will comprise two wells
tied into a subsea production manifold with production
fuids transported to
the existing North
Subsea 7 will
be responsible for
fabrication, transportation, installation and
and for additional
de-construction and pipeline suspension work concerning
the Echo Yodel feld at the Goodwyn Alpha platform.

Eagle will perform all offshore activities (due to start in
4Q 2015), with project management and engineering
handled from Perth.
Aker delivers subsea
Aker Solutions has delivered the subsea containment
system to Marine Well Containment Co. for use on its
The subsea containment assembly is designed to
contain a well-control incident by connecting and
creating a seal to prevent oil leaks. It can also be used
in a cap-and-fow plan to direct fuid to vessels on the
surface. The technology works under pressures as high
as 15,000 psi.
The equipment was delivered to the Marine Well
Containment Co. base in Ingleside, Texas. It weighs 170
tons and consists of a stack of adapters and connectors
assembled on a steel base.

EMAS AMC, the subsea division of EMAS, has christened and named the Lewek Constellation prior to its
departure to the Gulf of Mexico to commence work for
Noble Energy. The Lewek Constellation, an ice-classed,
multi-lay offshore construction vessel with ultra-deepwater pipelay and heavy-lift capabilities, is the company’s
fagship project-enabling asset.
The Lewek Constellation was initially conceptualized
in 2009 and its hull was successfully launched in 2012. It
measures 178 m (584 ft) by 46 m (150 ft), and is designed
to deliver projects in water depths of more than 3,000 m
( 9,842 ft).
Additionally, EMAS says that the Lewek Constellation
is only one of two vessels in the world in its class to
achieve the highest environmental and comfort notations,
with an ice-classed hull capable of transiting through 0.8
m ( 2 ft) of ice and a DP- 3 system. It also comes equipped
with an 800-metric ton (881-ton) Huisman multi-lay
system that is able to support both rigid and non-rigid
pipelines, a 3,000-metric ton ( 3,306-ton) Huisman offshore heavy-lift crane, two Schilling workclass ROVs, and
a portable reel system.
The vessel currently has a backlog of projects valued at
around $500 million
