Versatile Pacific Shipyards Inc. delivered the Arctic Class 4 icebreaker Henry Larsen to the
Canadian Coast Guard. Powered by an AC marine propulsion system that includes Wartsila
Vasa diesel engines and General Electric Canada synchronous generators, the Henry Larsen
can reach speeds of 13.5 knots in the open sea.

Dutch Yard To Build
Six Multipurpose Ships
The Dutch shipyard Van der
Giessen-de Noord was recently
awarded a contract by Van Nievelt,
Goudriaan to build six multipur-
pose carriers. The 6,000-dwt ships
will be built to carry containers, oil
products and bulk cargo.
The Detroit Diesel-powered catamaran ferry Jelang K was recently delivered to the U.S
Army for use at a missile test range in the Marshall Islands.

The Northern Vancouver yard of
Versatile Pacific Shipyards, Inc.
(VPSI) has delivered the Type 1200
Arctic Class 4 icebreaker Henry
Larsen to the Canadian Coast
Guard. She is now in operation pro-
viding large vessel escort service in
the Gulf of St. Lawrence during the
winter months and in the Eastern
Arctic in the summer months.
Commenting on the delivery of
the Henry Larsen, David Alsop,
president and chief executive officer
of VPSI, said the ship performed
well during her sea trials and "we
are confident the Government of
Canada and the Coast Guard are
taking delivery of a first class vessel
that will meet all expectations."
As reported in the September is-
sue of MARITIME REPORTER,
the Henry Larsen is 327.5 feet long,
has a beam of 64.6 feet and displace-
ment of 8,290 tons at a draft of 23.7
feet. She is powered by an AC
marine propulsion plant consisting
of three main generator sets, cyclo-
converters and synchronous motors.
Three Wartsila Vasa type 16V32
diesel engines each rated at 5,250 kw
at 720 rpm, drive General Electric
Canada ATI synchronous genera-
tors with brushless exciters. Each
generator is rated at 5,000 kw, 4,160
v, 6,250 kva at 720 rpm. Cullen Can-
ada Inc., Vancouver, B.C., Canada,
supplied the main propulsion gener-
ator sets.
Auxiliary power is supplied by a
625-kw Stromberg HSPTL 10/653
generator driven by a Wartsila Vasa
6R22 rated at 960 kw at 1,200 rpm.
She is also fitted with a Caterpillar
emergency generator set.
The Henry Larsen can accommo-
date a crew of 72, has a cruising
range of about 15,000 nautical miles,
a cruising speed of about 13.5 knots
and a total shaft horsepower of
12,000 kw through two Lips propel-
lers.
One special feature of the Henry
Larsen is her advanced Asea Brown
Boveri (ABB) Integrated Automa-
tion System. The system provides
true integration of control and in-
strumentation functions, integrat-
ing prime mover control with elec-
tronic governors, start permissives
and safety systems; alarm and mon-
itoring; fan, valve, pump and com-
pressor control; power management;
fuel consumption calculation and
presentation; and tank gauging.
Completed under a C$96.8-mil-
lion contract as one of several new-
buildings and modernizations
planned or underway in the Canadi-
an Coast Guard's Capital Projects,
the Henry Larsen is one of Canada's
largest icebreakers. To enhance her
icebreaking capabilities and in-
crease her maneuverability, she is
fitted with a Wartsila Air Bubbling
System, which reduces friction be-
tween the hull and the surrounding
ice. Additionally, she is fitted with a
heeling/stabilizing system by Inter-
ing of Germany through Jastram
Canada.
The icebreaker is named in honor
Nichols Brothers Boat Builders,
Inc., Whidbey Island, Wash., re-
cently christened the second of two
catamaran passenger ferries it has
built for the U.S. Army for use in
the Marshall Islands.
Built under a $1.8-million con-
tract, the 72-foot FB-817 Jelang K
will join the FB-816 Jera at the
Army's missile range in the Mar-
shall Islands. The 31-knot Jelang K
will be barged to the Marshall Is-
lands for use as a ferryboat for tech-
nical personnel working at the U.S.
Army Kwajalein Atoll test range.
With a beam of 28 feet 6 inches
and a draft of 5 feet 11 inches, the
vessel will carry 1,100 gallons of fuel
oil, 250 gallons of water, and 232
passengers at full load. She is pow-
ered by a pair of Detroit Diesel
16V92 TA 960-hp main engines sup-
plied by Pacific Diesel Power of
Portland, Ore. The engines are cou-
pled to ZF model BW250 reduction
gears with a ratio of 2.03:1, and 37-
inch by 36.5-inch, five-bladed bro-
nze propellers from Osborne Propel-
lers.
The two 50-kw Northern Lights
auxiliary generators are driven by
John Deere 4276 engines. Systems
Engineering provided propulsion
controls and Hough Marine, the
steering system. The vessel's air
conditioning was engineered by Cel-
cius Marine, Inc., with duct work by
Puget Sound Refrigeration.
The Jelang K is based on a design
by International Catamaran De-
signs Pty. Ltd., of Australia. Nichols
Brothers Boat Builders and Glad-
ding-Hearn Shipbuilders, Somerset,
Mass., are the only shipbuilders in
the U.S. licensed to build this type
of catamaran.
Electronics include a Data Ma-
rine LX201 fathometer, Standard
Communications VHF radio, Furu-
no FCR 1411/6 radar, Furuno
8030D radar, and Data Marine
LX50 speed log. The electronics
package was provided by Northern
Marine Electronics of Seattle.
Current contracts at the Whidbey
Island, Wash., yard include an order
for a 35-knot advanced technology
"wave piercer" catamaran from Cal-
ifornia Cruisin', as well as an order
for six passenger catamarans to be
delivered to Puerto Rico over the
next two years.
