Propulsion Update

MAN B&W And Pielstick Present New

V-version of 48/60 Diesel Engine

The German engineering firms of MAN B&W Diesel and S.E.M.T.

Pielstick have recently introduced the jointly developed V-version of the 48/60 engine.

The concept of the new V-type engine is based on the design prin- ciples of MAN B&W's successfully family of medium-speed 4-stroke in- line engines, the L 40/54, L 48/60 and the L 58/64. Having sold more than 140 engines of this type world- wide to the stationary and marine sectors, the V 48/60 to be marketed as a "proven but new engine."

Because of the power develop- ment requirements of 11,000 kW to 17,000 kW, it was decided to go with the in-line 48/60 engine as the basis for the new V-type. This made it possible to directly adopt numerous components such as cylinder cover, piston, cylinder liner, connecting rod, injection system, etc.

The 48/60 V-type engine is avail- able in 12, 14, 16 and 18-cylinder versions. Under ISO conditions and assuming a net calorific value of 42,700 kJ/kg, the specific fuel con- sumption is 178 g/kWh at 100 per- cent MCR, and 175 g/kWh at 85 percent load. The V 48/60 engine has been designed to burn even the

H-K 55 specification.

Both companies are primarily aiming the V 48/60 for power gen- eration in medium-scale and large- scale diesel power stations of 100

MW capacities and more. Using the engine for navy and merchant ma- rine ship propulsion is also possible.

MAN B&W and Pielstick believe a yearly demand of20 - 30 engines is realistic, with the majority of de- mand coming from the Far East,

South East and Central Asia and

Australasia.

Vianova Offers Line Of

Automated Handling &

Treatment Equipment

The Italian company of Vianova

S.p.Aoffers shipbuilders a complete line of automated materials han- dling and treatment equipment. The company's U.S. operations are now represented by Gerard Technology

Associates (GTA) in Thorndale,

Pennsylvania.

Vianova's Roblast system is de- signed to reduce labor requirements for automatic high pressure water cleaning, dust free sandblasting and painting of ship's hulls. The Roblast performance rates are:

High Pressure Water Cleaning 3600-7500 sq.ft./hr.

Dust Free Sandblasting 430-650 sq.ft./hr.

Painting (depending on film thick- ness 7500-10500 sq.ft./hr.

Several U.S. shipyard already use

Vianova magnetic cranes, steel con- veying equipment and treatment lines for shotblasting and painting steel plates, profiles and pipe. The paint marking system identifies plates and shapes to simplify mate- rials management and increase pro- ductivity. Automatic welding equip- ment and fume extraction systems are also available.

Vianova also provides ship tow- ing and centering systems for drydocks, complete with mechanized side blocks for support, and consult- ing services for shipyard production engineering.

Detroit's Marine Pollution

Control Tests New Method

For Oil Spill Cleanup

The Environmental Protection

Agency and Detroit's Marine Pollu- tion Control recently tested a new way to control oil spills. The test was conducted on the Detroit River.

The new method forces oil into areas where it can be pumped faster through the use of waterjets.

The Valdez and Persian Gulf oil spills are some of the major cleanup operations that Marine Pollution

Control has participated in over the past 25 years.
