Wärtsilä to supply power and positioning system for
Statoil's two new offshore drilling rigs
Wärtsilä Corporation, Trade and Technical Press
release, 23 January 2012 at 1 pm EET
The Wärtsilä power and positioning system solution
represents proven reliability as well as superior efficiency,
which results in lower operating costs, fewer emissions and
less maintenance. Furthermore, Wärtsilä's unique condition
monitoring system and the company's local service network
supports the operator in harsh environments.
Wärtsilä, the marine industry's leading solutions
provider, has been contracted to supply the power and
positioning system for two new drilling rigs ordered by Songa
Offshore AS, the Norwegian arm of the Cyprus-based offshore
drilling company. These so called cat D semi-submersible rigs
are tailor designed for use by Statoil in mid-water segments,
and are being built at the Daewoo Shipbuilding and Marine
Engineering Co.Ltd (DSME) shipyard in South Korea.
The contract for the power and positioning system was
signed in November 2011 and calls for Wärtsilä to supply for
each rig a total of six 12-cylinder engines in
V-configuration with ancillaries, and six Wärtsilä FS3500
main , as well as the integration of the entire system.
Additionally, the engines and thrusters will be equipped with
Wärtsilä's unique condition monitoring system. Delivery will
begin in 2012 and the first rig is scheduled to be
operational during 2014. Wärtsilä has an option for two
further rigs.
"The proven reliability and superior efficiency of the
Wärtsilä propulsion solutions were the major factors in the
award of this contract. Calculating the average load profile
for deepwater drilling rigs, the efficiency is approximately
three per cent better than those offered by competitors. The
high efficiency enables fuel cost savings and has also clear
benefits in terms of reducing carbon dioxide emissions (CO2).
Furthermore, the local Wärtsilä service network in Norway
will provide full support for the equipment," says Magnus
Miemois, Vice President at Wärtsilä Ship Power,
Offshore.
The semi-submersible rigs are custom designed for
efficient year-round drilling, completion, testing and
intervention operations in harsh environments and arctic
conditions. They will be operated on the Norwegian
Continental Shelf by Statoil, the international energy
company headquartered in Norway. The rigs meet the Det Norske
Veritas CLEAN-DESIGN criteria, meaning that the Wärtsilä
engines are IMO Tier 2 compliant.
Songa Offshore is an existing customer of Wärtsilä,
having earlier in 2011 taken delivery of eight thrusters for
the "Songa Eclipse" semi-submersible rig.
Scope of supply per rig:
Six 12-cylinder Wärtsilä 32 engines in
V-configuration
Six Wärtsilä FS3500 main steerable thrusters
Ancillaries
