CASE STUDY The Twin TF Marine Gas Turbine Propulsion Package: The Solution for High Performance In three different types of vessels, a unique propulsion solution is used to maximum effectiveness. CHALLENGE Provide 10,000 hp of ship propulsion power in a small machinery space while maintaining lightest possible weight. SOLUTION A twin marine gas turbine package employing direct mount and full support by the reduction gear. RESULTS Lightest power to weight package means speed requirements met in fast ferries, naval ships and megayachts. With the added flexibility of single or twin engine operation. Diesels can also be added for a CODOG package. What do the Royal Swedish Navy Visby class corvette, the Buquebus fast ferry Patricia Olivia and the Feadship superyacht Sussurro have in common? Besides superb naval architecture, and an ability to glide swiftly and gracefully across the seas, they all employ a Vericor Twin TF Marine Gas Turbine Package in their propulsion systems. The Package consists of two Vericor TF Series marine gas turbines coupled to a twin in / single out main reduction gear. This propulsion package delivers approximately 10,000 shaft horsepower to prop or waterjet and weighs three times less than the diesel engine equivalent. For the naval architect and the operator, the advantages are numerous: - Vericor marine gas turbines operate on diesel fuel and are controlled just like conventional diesels. - Operation on one or both gas turbines with ability to drop one engine off line and/or add engine while the other engine is operating. - Ability to orient Package in the ship with exhaust facing aft or forward. - The Twin Package MRG can be configured with a diesel engine input to give a CODOG powerplant Patricia Olivia Visby Class Sweden, The Mediterranean, Argentina .

CASE STUDY : The Twin TF Marine Gas Turbine Package Case Study Details and the Advantages of the Twin TF Gas Turbine The overwhelming advantage of the Twin TF Package is the low weight and small size as compared to other marine powerplants producing 10,000 hp. A modern high speed diesel engine of comparable power is over three times the weight and over twice the length. A key design feature of the TF engine is complete and direct mounting to the main reduction gear (MRG). This design feature contributes significantly to the weight savings of the overall package by eliminating a heavy base frame...
