Ultra Dynamics News

Two recent refits of waterjets are unique in one respect that they allow a direct comparison between waterjet brands, while everything else remains unchanged. Waterjets from Marine Jet Power were recently used to solve some significant propulsion issues and in one case the exchange even helped a yard to achieve its project goals leading to the fact that the yard finally was able to deliver the ships to the owners. In the first case, the operator of a 10-year-old vessel decided to change to MJP DRB jets due to significant service and corrosion issues on the existing waterjets.

Geislinger GmbH recently delivered its biggest torsional elastic coupling — a coupling with an outer diameter of 2.8-m and a weight of 36.3 tons. The coupling will be built into the drive line of a VLCC tanker, with an energy saving counter-rotating double propeller. More than 2,000 single parts were produced in the Geislinger works in Bad St. Leonhard and assembled in the works in Salzburg. The coupling transmits half of the 27,160 KW engine power at 74 rpm and in this way protects the gear box, which changes the direction of rotation for the backwards running propeller. This causes the energy of the swirling water in the gushing of the propeller to be used and therefore the degree of effectiveness is increased by about 14 percent.
