This has given us valuable experience, in order to apply the right design criterias and development of module-based ships' gearboxes with respect to their functions and strength.

All materials used in the gearboxes are carefully selected to secure the optimum conditions of the product, and to obtain life-long durability and safe operations;

  • Gearboxes for a high number of operational modes
  • Flexible design with several PTO/PTI configurations
  • Part of an integrated Propulsion System
  • High quality in materials and a robust design
Brunvoll Reduction Gear Design

Unique flexibility with module based design

On all gearboxes without an integrated PTO/PTI solution it is possible to choose amongst a wide range of PTO/PTI modules which may be connected to the main gearbox.

The modules are selected by definition of the function of the gearbox and the propulsion system, and might be primary or secondary driven with our without integrated clutch solutions for fully automatic operation.

  • All Brunvoll gearbox designs are based on modules giving a unique flexibility.
  • Ideal for hybrid systems with multiple engine configurations.
  • Wide range of Power take-off (PTO) and Power take-in (PTI) units.
  • Each gearbox is configured to each customer's requirements.
  • All gearboxes are designed in 3D, and FEM/FMEA analysed in order to secure strenght and reliability.

Single-in Single-out propulsion system with clutch + PTO type PF without clutch

  • This system contains a primary driven PTO without clutch, and is always running with the main engine.
  • The PTO can be used for generators or for pumps.

Single-in Single-out propulsion system with clutch + PTO/PTI type PF with clutch
