AT SEA.

SCROLL TO EXPLORE

At sea, Bergen engines power generators for offshore oil & gas installations and on board a wide range of ocean-going vessels. Bergen engines can also be found in direct propulsion applications.

From tugs and fishing vessels, to ferries, offshore supply and cruise ships, Bergen engines are a watchword for supreme quality and reliability in the marine industry.
