Stabilisers are essential on boats to ensure a smooth journey even when the waters are choppy, and could be seen as highly important on luxury yachts where the owner is seeking a specific experience.
Take the luxurious Hampshire II as an example. This is reported to feature a real log burning fireplace in the dining room, an ‘extraordinary’ bar on the bridge deck, a wine cellar with underwater viewing window, and a cinema on the lower deck, as well as a helipad, swimming deck, diving boards and so on.
Following extensive sea trials, the Hampshire II docked in Barcelona before being handed over to the owner; and it was here that the decision was made to replace the main drive motor on the stabilizer. However, when the service crew went to assess the stabilizer they saw that not only was the whole engine room decorated in white, but that the motor was mounted in a small space – and no oil or grease stains would be acceptable!
Wim Bruil, customer care manager for Rotor, commented: “Access wasn’t great and we could see that using a crane or winch would increase the chances of damaging some of the paintwork or decoration. So we started looking at options for dismantling the original motor in situ and taking it out one component at a time. Naturally this lead to the same idea for installing the new one, although assembling, testing and commissioning the new motor in the engine room would be a far greater task.”
Meeting the application demands, the new motor was a 30kW Rotor AC unit, weighing in at 320kg when fully assembled. Rotor manufactures standard
and special motors up to 1000kW to IEC, DIN and marine specifications, regularly supplying complete drive systems for pumps, ventilation systems, davits, cranes, port machinery, hydraulic systems, compressors and various other pieces of equipment. So, while the Hampshire project was unusual, it was well within the company’s scope of experience.
“We have installed motors in the desert and the arctic, in theatres, hospitals, sewage works, offshore, subsea, in tall buildings and at the bottom of mines,” recalls Bruil. “We have worked in some of the most arduous environments imaginable, but coping with a luxury yacht in a beautiful Mediterranean marina was new territory for us.”
