Circle 254 on Reader Service Card of these eductors is supplied from the fire and general service pump in the engine room via the general ser- vice seawater line of the upper deck.

Hold washing is carried out with portable machines.

The VLBC has an overall length of 983.6 feet, beam of 154.9 feet, depth of 80 feet, and design draft of 58 feet. The main engine is a super- long-stroke Mitsubishi/Sulzer 6RTA84 diesel with maximum out- put of 18,390 bhp at 71 rpm and normal output of 15,650 bhp and 67 rpm. Engine derating and a large- diameter propeller improve fuel economy. A module type Halon 1301 fire extinguishing system is installed in the engine room.

The ship's electrical generation system consists of a turbogenerator as the main power source, two diesel generators as the supplementary power source, and an emergency-use diesel generator. Through the use of a dual-pressure and hot water flush steam type of exhaust gas economiz- er, it is possible for the turbogenera- tor to provide all of the electric pow- er needed for normal seagoing use.

The accommodations make use of a gateway type wheelhouse to re- duce wind resistance. Mitsubishi reaction fins are installed just in front of the propeller to improve the propulsion efficiency.

A total of eight mooring winches are provided.

ORMOND

Mitsubishi

The 169,247-dwt very large bulk carriers Ormond, built at the Naga- saki Shipyard of Mitsubishi Heavy

Industries, Ltd., was delivered early this year to Whichin Company Ltd.

The state-of-the-art VLBC incorpo- rates the latest energy-saving mea- sures and several labor-saving de- vices, including a hold-cleaning sys- tem developed by Mitsubishi.

The Ormond is a flush decker with transom stern and Mitsubishi bow, with engine room and living quarters located aft. The cargo space is divided by eight transverse bulkheads into nine holds. The No. 6 hold can also be used as a ballast tank, and the odd-numbered holds are designed to carry iron ore. Each hold has a large, two-panel, side- rolling steel hatch cover and makes use of an automatic hydraulic type cleat system.

Two cleaning eductors are pro- vided in each cargo hold to make it possible to discharge large particles of iron ore from the hold along with the cleaning water. The drive water 22 Maritime Reporter/Engineering News

The big icebreaker Otso, ordered in 1984 by the Finnish Board of

Navigation, was delivered early this year by Wartsila's Helsinki Ship- yard. She is the first of two techno- logically advanced icebreakers of a new type. The second vessel was ordered in December 1985 and is scheduled for delivery in January 1987. The Otso and her sister ship will replace three icebreakers of the

Karhu Class, which are more than 25 years old and too small to assist today's much larger merchant ships.

Compared with the Urho Class icebreakers built in the mid-70s, the

Otso has a 21.33-foot shorter water- line but a beam 1.3 feet wider. This allows efficient assistance to the bigger ships in use today. The de- sign draft is only 24 feet, less than the Urho Class, making a larger number of harbors accessible to the new icebreaker. The Otso has an overall length of 324.8 feet, beam of 79.4 feet, and maximum draft of 26.25 feet.

The main machinery comprises four Wartsila Vasa 16V32 diesel en-
