COGAG propulsion Gearbox

COGAG propulsion Gearbox

Stork is stepping into a new market with this new developed gearbox: Vessels with a high demand on cruising speed. The gearbox is designed for an input of two Vericor TF50B Gasturbines. The gasturbines each have 4,2 MW output power at 16 000 rpm. The driven end puts the 8,4 MW towards a waterjet at 896 rpm.

Applications can reach from fast attack vessels to luxury yachts. Together with our partner Vericor we designed and developed this gearbox. The combined experience helped to create a low weight, highly reliable propulsion system.

The gearbox is directly the integral support of the gas turbines, is designed using SSS clutches in a quill shaft setup, and has a brake system. All other auxiliary equipment is also supplied by Stork, like the oil, water and hydraulic pump, a turning device and off course a complete monitoring system.
