HMC to scrap semisubmersible crane vessel
After nearly 40 years, Heerema Marine Contractors (HMC) will
retire its semisubmersible crane vessel Hermod at the end of the year.
Designed and constructed in the ’70s, the Hermod and her sister vessel
Balder were the first semisubmersible crane vessels of its kind in the
offshore construction industry. The semisubmersible concept was
developed with the aim to extend the operability in the harsh North
Sea environment and to deliver superior lifting capacity. This, the
company says, allowed it to work faster and during more months of
the year than the conventional mono-hull crane vessels of the time.
After delivery by the Japanese Mitsui yard in 1978, the Hermod’s
first job was the installation of the Piper A platform on the UK continental shelf. She executed her first project outside the North Sea
in Brazil in the mid-’80s, followed by projects in the Gulf of Mexico,
Southeast Asia, and Africa.
HMC pointed out that throughout her career, the Hermod worked
in more than 25 countries and was involved in several “first-of” instal-
lation projects including:
• Installation of the first North Sea TLP (Hutton) jointly with Balder
• Installation of the first deepwater foundation piles of the first TLP
in the Gulf of Mexico (Auger) in 870 m ( 2,854 ft) of water in 1992
• Installation of the Tombua Landana compliant tower foundation
in Angola in 2008 comprising the world’s largest single piece
foundation piles 2.7-m ( 8.9-ft) diameter, 190-m (623-ft) long and
weighing 850 m T each
• Removal of the first large platform in the UK: North West Hutton
• The heaviest lift performed by the Hermod was the Peregrino
topsides in Brazil in 2010 with a dry weight of 6,287 m T.
The Dockwise Vanguard will transport the vessel from the port of
Rotterdam, the Netherlands, to the Zhoushan Changhong International
Ship Recycling yard in China for dismantling and recycling. HMC said
that the demolition will be performed in a safe and responsible way,
in accordance with the Hong Kong International Convention for the
Safe and Environmentally Sound Recycling of Ships and in line with
the European Union Ship Recycling Regulation.
Transocean scraps six floaters
Transocean Ltd. has reported that it will retire the ultra-deepwater
drillships GSF Jack Ryan and Deepwater Pathfinder; the ultra-deepwater
semisubmersibles Sedco Energy, Sedco Express, and Cajun Express;
and the deepwater semisub Transocean Marianas.
The rigs will be classified as held for sale and will be recycled in an
environmentally responsible manner. All six rigs were previously cold
stacked. The company will recognize an impairment charge of about
$1.4 billion during 3Q 2017 associated with these actions.
President and CEO Jeremy Thigpen said: “We continue to enhance
the quality of our fleet through the addition of new, high-specification
assets, and the retirement of older, less competitive rigs.
“We remain committed to providing our customers with the most
Subsea construction vessel ready
technically capable and highest quality ultra-deepwater and harsh
environment assets in the industry, and will continue to objectively
evaluate our rigs and high-grade our fleet as the market evolves.”
In addition, the drilling contractor recently received an early termina-
tion notice from a Chevron subsidiar y for the ultra-deepwater drillship
Discoverer Clear Leader. The drilling contract termination will be effec-
tive in November 2017. The original expiration was October 2018. In
accordance with the contract terms, Transocean will be compensated
through a lump-sum payment of about $148 million in contract termina-
tion fees. The payment is expected to be received in 4Q 2017.
for Shah Deniz Stage 2 duty
The Baku Shipyard has launched the Khankendi, a new flagship
subsea construction vessel for the Shah Deniz Stage 2 project in the
Azeri sector of the Caspian Sea.
The Shah Deniz consortium says that the $378-million vessel was
specifically designed and built to install the biggest subsea production
system for the Shah Deniz Stage 2 project. The Khankendi will now
be deployed to the Shah Deniz field where it is expected to perform
subsea installation and construction work over the next 11 years.
The vessel is 155 m (509 ft) in length and 32 m (105 ft) in width
with 2,000 sq m ( 21,528 sq ft) of deck space. It has a total weight of
17,600 metric tons, a carrying capacity of 5,000 metric tons at 6. 5 m
( 21 ft) draft and two engine rooms with 6 x 4.4-MW and 2 x 3.2-MW
It is equipped with dynamic positioning to allow working in 3. 5 m
( 11 ft) significant wave height, a 900-metric ton main crane capable
of placing 750-metric ton subsea structures down to 600 m ( 1,968 ft)
below sea level, an 18-man two-bell diving system, two work-class
ROVs and a strengthened moonpool.
The Khankendi is said to be able to carry out complex activities
without the need for anchors. The vessel has a maximum capacity of
175 people on board, including the marine crew and discipline specialists. The personnel include both Azerbaijani nationals and expatriates
with plans for extensive training, leading to the full nationalization
of the staff. •
