Engineers and manufacturers of efficient, reliable marine propulsion products for ships, boats and barges. (Successors to Murray & Tregurtha) and co-ordination were carried out by MacGregor. The work was exe- cuted for Island Princess in Genoa,

Italy, and for Pacific Princess in

Singapore. The MacGregor Group operates through 30 companies in 25 major shipping and shipbuild- ing countries and is expanding its local presence worldwide.

Another company which focuses its product development on vessel safety is Valmet Power

Transmission. Valmet has deliv- ered to Wartsila a marine propul- sion gearbox for a chemical tanker which is equipped with a new PTI drive configuration. The ship, hull

No. 1201, is currently under con- struction at Italy's Apuania ship- yard. This solution is designed to increase machinery related safety and enhance operational economy.

The concept features a single input/single output gearbox in the horizontal form, three hydraulic multi-disk clutches, which are incorporated in the gearbox, and a

PTI drive. The main clutch is for engaging the propeller shaft, while the two others are for the PTO and

PTI drive respectively. The PTI drive includes a pony motor.

In the event of engine failure at sea, Valmet's new PTI drive with its unique clutch solution reported- ly makes it possible to propel the ship away from hazards. The pony motor, with its shaft integrated in the gearbox, is connected to the

PTO shaft to accelerate the shaft alternator. After the alternator has reached its nominal speed, the main and the PTO clutches are dis- engaged and the propeller shaft is started by engaging the PTI clutch.

The propeller is then driven by the shaft alternator, which is function- ing as an electric motor and is sup- plied with power from the genera- tor sets onboard. Besides increas- ing safety, the unit is designed to make it possible to service the main engine during a call at port, therefore requiring less separate lay days needed for maintenance.

CAD/CAM solutions have also opened up a new forum for increas- ing design efficiency and safety, and Finnish companies such as

Nupas-Cadmatic — a relative new- comer to the market — are mak- ing a big impact. The company, which is a joint venture between

Holland's Numeriek Centrum

Groningen B.V. and Finland's

Cadmatic Oy, strives to deliver flexible, easy to use software solu- tions. To date, shipyards such as

J.J. Sietas and Neue Brandt Werft in Germany, Ulstein Verft in

September, 1996 57

Norway and Chin Fu in Taiwan, have purchased and started using

Nupas-Cadmatic shipbuilding soft- ware. While most of the product's users are in Europe, the company expects substantial growth in the
