After protection has been applied and the final inspections have been made, the propulsion units are lifted on the truck that takes the units to the Port of Rauma.

Rolls-Royce High production peaks FSP's third key feature is flexibility, as the production amounts may occasionally rise very high. Site Manager at the FSP Rauma unit, Hannu Koivisto, explains that if necessary, FSP is able to bring more surface treatment workers from the company's other surface treatment shops. ”Schedules must be kept also during high production peaks. For this reason, a reliable surface treatment partner is vital,” states Teuvo Palo, Plant Manager at Rolls Royce Oy Ab. Propulsion units can rotate 360 degrees around the vertical axis. The propulsion unit, weighing up to 100 tons, can have a propeller diameter of 4.5 meters. ”The surface treatment phases consist of shot blasting, washing, protection and base coating. The underwater part of the propulsion device gets a stronger surface treatment than the other painted parts, which are coated with polyurethane," Koivisto explains. New production facilities in Rauma also ensure a short drying

time, because the temperature in the painting hall can be increased up to + 50 degrees Celsius. This contributes to rapid lead times and adherence to delivery schedules. After the coverings have been taken off and the final inspections have been made, the propulsion units are lifted on the truck that takes the units to the Port of Rauma, from where they are sent by sea to the client. Strict inspections The cooperation also includes quality control and strict inspections that FSP carries out during different work phases such as documentation. This is essential because RollsRoyce has specified high quality and environmental requirements and other standards. The goal is to produce a corrosion resistant surface treatment, as the surface of propulsion devices has to endure demanding conditions. The cooperation between FSP and Rolls-Royce has progressed well so far, because inspections have been passed and there has been no reason for recalls. ■

At the moment, Rolls-Royce Oy Ab, operating in Rauma and in Kokkola, manufactures marine products, such as winch systems, propulsion units and waterjet units. Its clients include international shipping companies and shipyards. Up to 99.5 percent of production goes beyond Finnish borders. The Rauma unit of RollsRoyce has become the global leader of propulsion unit production and it designs and manufactures 500 propulsion units annually. The power range of the units is from a few hundred kilowatts to 10 megawatts. The propulsion system that meets the requirements of the client can be customised for different vessels by utilising modern technology. Propulsion systems are manufactured for e.g. tugboats, icebreakers and other specialised vessels. In its two Finland-based factories, the company employs nearly 500 industry experts. The annual turnover is approximately 600 million euros. ■ SURFACE 7
