Icebreaking Supply Vessel
M/V Miscaroo Delivered
By Vancouver Shipyards
Vancouver Shipyards Co. Ltd. has delivered the M/V Miscaroo to its owner, BeauDril Ltd., a subsid- iary of Gulf Canada Resources Inc.
Vancouver Shipyards reports it is one of the most powerful supply vessels in the world and the first icebreaking supply vessel to be built in Canada to Canadian Coast
Guard Arctic Class 4 regulations.
The M/V Miscaroo is the second of two 14,900 BHP icebreaking/an- chor-handling supply vessels built for operation in the Arctic by
BeauDril. Designed by Robert Al- lan Ltd. the M/V Miscaroo will be part of Gulf Canada Resources Inc. drilling operation in the Beaufort
Sea, and is designed to operate in conditions of — 50°C and will break level ice up to 1.2M thick at a con- tinuous speed of three knots.
Propulsion machinery consists of a geared diesel-CPP combina- tion. Four main Wartsila Vasa 8R32 diesels are rated 3,725 bhp each at 750 rpm. The engines in pairs drive Lips controllable pitch

The M/V Miscaroo incorporates several unique features to en- hance performance in ice. Among these are a hull form incorporat- ing a forefoot wedge designed to deflect ice from the path of the vessel, and large bossings over the propeller nozzles and rudders to protect them from ice.
Maneuverability is enhanced by electrically driven thrusters fore and aft. The forward thruster is a 1,200-hp Omnithruster and the aft thruster is an 800-hp KaMeWa controllable-pitch propeller thrust- er. The Omnithruster has been modified to incorporate an ice hull lubrication system, ejecting an air water mixture along the forward half length of the vessel.
Other major equipment onboard includes a Burrard Iron Works quadruple drum anchor-handling/ towing winch of 150-ton line pull capacity, two Hydralift deck cranes and Gearmatic tugger winches.
Miscaroo has been designed and equipped so that each of the 22 crew members has a private room.
Amenities include large lounges, recreational spaces and a sauna.
Detailed attention to vibration and noise isolation has resulted in noise levels less than 63 dB throughout the accommodation while under full power.
The 79.25m by 17.2m vessel has a molded depth of 9.7m, and a de- sign draft of 7.5m. The vessel has a capacity of 1,250 tons of fuel oil; 1,100 tons of ballast water; 150 tons of potable water; max. deck cargo of 1,400 tons; and a deck cargo area of 450 m2.
Navigation and communication equipment includes radar by Decca, gyrocompasses by Sperry, Wagner autopilot, Honeywell navigation echo sounder, Magnavox satellite/ omega navigator, JMC automatic direction finder, Marconi SSB ra- dios, Sperry doppler log, Alden
Weatherfax and Simrad and Mar- coni watch receivers.
