Starting point

The old diesel units of the MS Dragon had reached the end of their lives and needed to be replaced. The Schottel rudder propeller was also outdated. The customer wanted to convert to a shafting system. Shiptec was commissioned with the planning, design and conversion.

Implementation

After dismantling, a new Scania industrial engine was installed, which had previously been converted to a water cooling system. A diesel particle filter system was also installed in order to be able to meet the new emission regulations in line with Euronorm Stage V. A new fire extinguishing system, on-board power generator and 2 small bow thrusters were also installed. All of the electrical installations were also renewed. A new coat of paint below the waterline rounded off the works.

Challenges

To standardise the SNG fleet, the customer wanted the propulsion drive converted from a rudder propeller to a shafting system.

The biggest challenge was the limited space, as the engine room had not been designed to accommodate this. Using a V-gear, which was now installed in a bulkhead in front of the engine room, we were able to find a solution and carry out the conversion successfully.

The partnership between the SNG and Shiptec AG on Lake Lucerne was further strengthened by the renovation of the MS Dragon. New joint projects are planned for the future.
