Turbo-Technik: Rescuing A "Prinsesse"

A summer day in July proved to be unfavorable for Color

Line, whose passenger ferry, Prinsesse Ragnhild experi- enced a fire in its engine room en route from Kiel to Oslo.

The vessel's fire was apparently caused by a defective fuel pipe. The job of repairing the ship was granted to the Ger- man team of Blohm + Voss Repair GmbH, Hamburg, who assured Color Line with a quick turnaround, ensuring that the vessel was kept out of a service for a minimal amount of time, due to its tight cruising schedule. Subcontracted by Blohm + Voss was Turbotechnik Repairyard of Wil- helmshaven, who would perform fire damage repairs to the two Stork Werkspoor Diesel-built main engines,

SWD 20 TM 410 (14,000-hp each). The vessel's star- board main engine and crankshaft engine had previ- ously been renewed during scheduled repairs in Kiel during 1996. Work for the main engines' repair, includ- ed reconstruction, comprehensive repair or renewal of all damaged piping, control and pneumatic lines and equipment, as well as new alignment and re-choking, adjustment and final commissioning. The starboard main engine was examined at a greater length and dis- mantled, since it was the source of the fire, with the cylinder block being lifted up to car deck for thorough overhaul. Camshafts were removed for full inspection, and the crankshaft was brought ashore for dimensional deflec- tion measurements. The bed plate and main bearing were controlled and measured. A temporary intermediate plat- form was constructed on staging above the main engines proceeding the installation of the major components, so that repairs could be expedited and other trades could con- tinue work in the area.

Smart Electronic

Level Switch with

No Moving Parts

The Sea Switch Two was designed and patented for all tank applications. The Sea Switch Two offers a reliable solution for liquid level detection and control for cargo, ballast, and storage tanks, without any moving parts.

The Sea Switch Two uses a fully static system that is based on the propagation of an acoustic wave into a metallic rod. A piezo-electric sensing element produces a wave along the rod. As the liquid reaches the sensing element the oscilla- tion stops and the alarm is activated.

The Sea Switch Two sensor detects high, high- high, or low level in any liquid with an alarm output given by a dry contact or current loop change 6-18 mA. • Easy installation • Self-test built-in • Fully static system - no moving parts
