Totem Ocean has announced that Wärtsilä will supply
main engines, generators and integrated LNG storage and fuel
gas handling systems (LNGPac
) for one of the largest
conversions ever undertaken in
John Parrott, president of Totem Ocean, cited
Wärtsilä's proven technology
as a deciding factor in
selecting the company. Parrott emphasized that "maintaining
reliable, on time service is critical to Totem Ocean's
customers as well as the economy and citizens of Alaska."
The contract was signed in the fourth quarter of 2013, and
executives from both companies met on February 17 in Tacoma,
Washington, to announce the project.
"Today marks the beginning of a long relationship between our
two companies," said Parrott. "Our relationship will outlast
to extend over the 35-plus
year life of our vessels."
Totem Ocean's fleet of two Orca Class roll-on/roll-off cargo
ships -- M.V. Midnight Sun and M.V. North Star -- transport
about one-third of all the goods required by the inhabitants
of Alaska. Cargo includes essential items such as food,
household goods, vehicles, construction
military supply support.
As a result of the conversion, the Totem Ocean vessels will
set new standards for environmental responsibility by
reducing sulphur oxide (SOx) emission by 100%; particulate
matter (PM) by 91%; nitrogen oxide (NOx) by 90%; and carbon
dioxide (CO2) by 35%.
"It is an unprecedentedly exciting time to be in the maritime
industry," said Björn Rosengren, CEO of
Wärtsilä. "Economic constraints and the need to
comply with environmental legislation have combined to
accelerate the switch to LNG
"Wärtsilä is uniquely positioned to enable this
transition since we have been a leader in developing the
for nearly 30 years,"
he added. "We look forward to working with TOTE on converting
the Midnight Sun and North Star to LNG so that they can
realize the benefits that LNG as a marine fuel can provide."
- Each of the vessels will be equipped with four
12-cylinder Wärtsilä 50DF dual-fuel engines and
- Wärtsilä 50DF engines have been designed to
give high output combined with fuel flexibility, low
emissions, efficiency and reliability
- Engines can be run either on natural gas, light fuel oil or
heavy fuel oil
- Wärtsilä also provides the vessels with two
1100 m³ LNG fuel storage tanks and the
associated automaton and fuel gas handling systems
- In addition to the equipment, Wärtsilä is
taking responsibility for the design, engineering and integration of the system, and
project and site management for
its scope of supply
"We are seeing a transformative change in the marine industry
with the switch from oil based product to natural gas
," said Quentin
Stewart, sales manager for Wärtsilä's ship power
business in North America.
