Partrac Completes
Tidal Energy Site
Measurements
Partrac completed
oceanographic meas-
urements at a fifth tidal
energy site in the UK,
and have indicated that
further measurements
have already been pro-
grammed at three
more sites in 2011. By
their very nature, tidal
energy sites present a
challenge to acquiring
high quality data. The
limited tidal window in
which to operate (only
10 minutes at some
sites), is the most obvi-
ous problem. The issue
is further complicated
by irregular seabed
conditions including
rock fissures, which
present difficulties in
emplacing the kit
securely on the seabed
but which are largely
unknown prior to get-
ting out to the site.
Partrac have evolved
with the industry
requirements in order
to meet the oceano-
graphic challenges that
each individual site
presents, tailoring the
methods used to the
tidal and seabed condi-
tions at each site. As a
result of this process,
Partrac have now com-
pleted 28 individual
deployments at tidal
energy sites, in each
case delivering 100%
high quality data return.
Partrac and their team
are understandably
very proud of this tech-
nical achievement.

Gaoh Offshore signed a Letter of Intent
covering the design development and con-
struction of its multi-purpose wind farm
development vessel, the Deepwater Installer.
Gaoh Offshore and STX Offshore &
Shipbuilding Co., Ltd. (STX O&S) signed
the Letter of Intent [LOI] at the end of 2010
and board approval was given last month.
The LOI is for construction at the STX
Dalian Shipbuilding Complex in China after
a period of joint further development giving
both companies a commercial interest in the
design. Work will focus on fulfilling the
requirements of Round 3 UK wind farm
operators and Gaoh and STX will combine
their expertise to provide innovations that
particularly benefit installation in deeper
water, further offshore. To that end, Gaoh
will use the North Sea engineering expertise
of one of its key shareholders, Houlder
Limited. The vessel is a 140m DP2 jack up
capable of operating in the central North Sea
area on a year round basis and surviving the
100 year storm criteria on site. It can handle
up to 16 3.6MW turbines each trip while
minimizing both port loading and offshore
installation time. The design also incorpo-
rates a 1600 ton crane and under deck stor-
age to further reduces per turbine installa-
tion, commissioning and maintenance costs.
This true multi-functionality adds to the
design’s flexibility and ability to deliver opti-
mal cost efficiencies to safe, efficient and risk
optimized installation and field support
activities. Officials of both companies
including K. J. Hong, Vice Chairman &
CEO of STX O&S and Peter Hickson, CEO
of Gaoh, attended a signing ceremony in
Korea

Ahead of the forthcoming ADCI
Consensus Standards for Commercial
Diving, Revision 6 requirement, IMO
directives and Class
Requirements, Cal Dive
International has begun a
program to upgrade all
Saturation Diving
Systems with hyperbaric
rescue capability. Utilizing the expertise of
Arc Controls, the leading ASME/PVHO
fabrication shop on the Gulf Coast, Cal
Dive has already begun design and fabrica-
tion work on these systems. Using key per-
sonnel and machinery, Arc Controls is con-
structing ASME/PVHO, ABS, Lloyds, and
DNV compliant
Chambers/Systems at their
Mobile, Alabama facility.
Coordinating onsite is a
team of Cal Dive techni-
cians working to make
these systems ready for installation. Both
Cal Dive and Arc Controls are committed
to building systems meeting requirements
to be used anywhere in the world.
