Navilus GCL Gears Chosen

For Fast Ferry Project

Waterjet gearbox Navilus GCL.

LOHMANN + STOLTERFOHT

Navilus GCL gear units have been chosen for a Danish passenger ferry to be manufactured by Norway's

Mjellem & Karlsen.

The ship, to be delivered in 1995, will provide 32-knot service between the Danish ports of Grenaa and

Hundested.

Powered by four waterjets driven by MTU diesel engines with a total output of 23,200 kW, the Navilus

GCL gear units will reduce the en- gine speed of 1,200 rpm to the speed of the waterjet, which is 548 rpm.

The tooth flanks of the gearwheels are case-hardened and ground; all shafts carry an anti-friction bear- ing.

Integrated multiple-disk clutches allow engagement/disengagement of the gears as desired.

Geislinger: Noise, Vibration

Reduction Top Priorities

GEISLINGER, known as a spe- cialist in solving torsional vibration problems, will focus on its Torsional

Vibration Dampers at SMM '94.

Recently a number of prestigious vessels have been outfitted with this product, including the Eleo Maersk built at Odense shipyard and the

Norasia built at HDW shipyard.

Geislinger's product range reaches from camshaft dampers with a di- ameter of approximately 250 mm to crankshaft dampers for four-stroke engines (GD4), and torsional vibra- tion dampers for two-stroke engines (GD2).

The latter reach diameters up to 11.5 ft. (3.5 m). One GD2 damper will be exhibited on the Geislinger stand in its original size.

The company also plans to high- light its other products and recent developments.

MTU Powers Prestigious Fast

Ferries

MTU provided two 16-cylinder series 595 engines for the highly publicized Aquastrada I fast ferry, delivered last year, and has been tapped to provide an identical sys- tem for the new Aquastrada II, a second ferry of the same construc- tion, for Italian operator Tirrenia.

The second vessel will carry up to 450 passengers and 120 cars in ser- vice between La Spezia and Olbia on the island of Sardinia at a cruis- ing speed of 43 knots.

As with the first vessel, products from MTU-Elektronik will handle a great deal of the data management processes on board.

Among other items, the gas tur- bine and the diesels are electroni- cally governed and controlled by the ECS engine control system.

Renk Tacke: Low Noise,

Smooth Running Gears

RENK UND RENK TACKE will provide details of its latest gearing solutions and delivery programs at

SMM '94.

The Renk Tacke Augsburg works recently demonstrated one of its new 30,000-kW gear units for theFinnjet ferry to a group of marine experts via a test bed.

According to the company, low noise and smooth running are the behavior characteristics of this spe- cial propulsion gear—criteria which are critical to securing business in the burgeoning ferry and cruise liner market.

The latest delivery from Renk

Tacke is two gear units for the new

P&O cruise liner Oriana being built at Meyer Werft.

At 106 tons per gear, they are the largest marine gears built by the

Renk Tacke Rheine works to date.

Each father and son gear system transmits a power of 43,000 kW to a controllable-pitch propeller and in- corporates a 4,200-kW shaft alter- nator which can be used as an elec- tric motor.

At the Hamburg Show, the com- pany will also provide details on its new gear unit developments for fast ferries.
