PROPULSION UPDATE

The 300-passenger Han Ma Eum Ho catamaran passenger ferry is powered by Paxman Diesel 18CM engines.

Paxman Diesel Helps Power

Hyundai-Built 147.6-Foot Ferry

Paxman Diesel has sold two

Valenta 18CM engines to Hyundai

Heavy Industries for use on the new 45-meter catamaran passenger ferry, the "Han Ma Eum Ho" (Big

Heart).

Paxman reports that design im- provements on the 18CM, as well as the powerplant's established repu- tation, was key in winning the order in the very competitive high speed ferry market.

Design improvements include an

SG iron crankcase, which is signifi- cantly stiffer; fuel pump camshaft, governor drive and idler gears had all bearing areas improved, to give greater overall stability to the gear train; and a stiffer valve gear cam- shaft was fitted, and bearing areas on the rocker gear were increased, to provide longer life.

A single Elliott turbocharger is now fitted, to facilitate the high en- gine rating, giving approximately nine percent improvement in spe- cific output over the earlier Valenta 18RP200CM range.

The two Valenta engines for the

Han Ma Eum Ho are continuously rated at 4,050 bhp at 1,550 rpm, driving through twin Niigata 1.95:1, reverse reduction gearboxes and

KaMeWa 80S waterjets.

Full engine protection is provided by a Kidde Graviner oil mist detec- tion unit and Amot protection switches. Regulateurs Europa con- trols are used for bridge instrumen- tation and local alarm panels. En- gine control is also provided by

Regulateurs Europa with the Vi- king 22 digital electronic control system.

The 300-passenger catamaran, which is scheduled to enter service in March of 1993 with the Hyundai

Transportation Company, can carry 20 tons of fuel in two tanks and has a range of 800 nautical miles. It designed for a continuous speed ( 35 knots, and has a displacement < 230 tons.

Odense Steel Christens

Double-Hulled Supertanker

Odense, Denmark-based Odense

Staalskibsvaerft, A/S, recently chris- tened one of the world's first double- hulled supertankers, the 298,900- ton Eleo Maersk.

The double-hull concept, which is already in use on many smaller tank- ers and cargo ships, is that in the event the ship's outer hull is breached during a collision or grounding, the inner hull will escape serious dam- age and prevent a catastrophic oil spill.

Spurred by U.S. ship safety legis- lation included in the Oil Pollution

Act of 1990, naval architects from

Japan to Denmark are now compet- ing to develop ways to build a safer supertanker.

While no ship is unsinkable, many marine experts are convinced that the world tanker fleet would be sig- nificantly safer and fewer oil spills, such as the "Braer" grounding off the Shetland Islands, would occur if this type of construction becomes standard.
