Kumera’s front-end gearboxes drive auxiliary vessel systems like firefighting pumps (FiFi), hydraulic pumps, generators, compressors, etc. Kumera has a large range of standardized front-end gearboxes, with multiple Power-Take-Off (PTO) and Power-Take-In (PTI) capability, allowing the gearboxes to drive 1-8different auxiliary systems. Using a Kumera front-end gearbox will allow running several auxiliary systems in a very reliable, cost-effective way, with a compact installation of the equipment
The pump itself is typically positioned 30-50 meters down from the platform deck, below the sea surface. Traditionally, bevel gearboxes are used for this application. They are designed with a hollow output shaft in order to connect the water pump drive shaft effectively to the gearbox
Kumera manufactures right angle gearboxes to drive bow thrusters for different vessel types. Bevel gearboxes used for this application have a robust and cost efficient design specific for this application
Kumera Corporation has a solid industrial tradition, delivering more than 200.000 transmissions to industrial applications worldwide. The Kumera range of industrial gearboxes will cover most needs within industrial segments such as Pulp & Paper, Wood Handling, Chemical & Process Industry, Mining and Material Handling & Processing, Cranes, etc
A typical hybrid application today is utilizing one diesel engine, and one electric motor, often including a battery pack. The electric motor can also be of a type which can be used as a generator, allowing the battery package to be charged underway. Using batteries, the vessel can have a pure electrical mode, resulting in no emissions, in turn creating a more pleasant work environment on deck, at the same time protecting the environment. However, for a hybrid gearbox, all types of power sources can be used, i.e. diesel, electric, LNG, etc., and they can also be the same type of power sources. For instance, for the BB Power tug shown above, a combination of two diesel engines were used for each gearbox, in a father-and-son configuration.
