Rotor refurbishment

The luxury cruise ship Seven Seas Voyager can comfortably accommodate 700 guests on nine passenger decks, where they are treated like royalty on their voyage to Spain, Morocco, the UK, Croatia, Greece, Italy or France – in fine restaurants, the elegant casino, the outdoor pool with whirlpool, or even while playing golf on board. In September 2011, a dozen SCHOLPP employees refurbished the ship’s two rotors at Marseille harbour so that the Seven Seas Voyager could once again head out to sea at its top speed of 20 knots. Each of the 32-tonne rotors has a 7-megawatt drive with a top speed of 170 revolutions per minute. The SCHOLPP supervisors and specialist fitters transported three portal cranes to Marseille for the project. Aside from a 3° incline, one particularly tricky challenge was the extremely small gap of just 2.3 millimetres from the stator. More like threading a needle than an installation.
