Kato Engineering 500kW to 25MW Alternators and Motor-Generator Sets

Reliable power is an absolute must when you’re miles out to sea in tough conditions and the stakes are high.

When you use Kato™ generators (alternators) for main, essential or emergency power generation offshore, you gain better control over the industry’s inherent risks. Kato™ generators are the most reliable in the world.

Custom generator design

Advanced design software and an experienced engineering staff ensure your Kato™ generator meets your specific requirements.

Starting with the specification stage, Kato Engineering works with you to design a generator to match your engine or turbine while taking your entire project into consideration, whether it is for you or your customer. We examine all the variables that a reliable power system demands, such as power requirements, duty cycles, environment and paralleling needs.

Kato Engineering profile

Kato Engineering has been providing power for the offshore oil and gas industry since the early 1950s. On FPSOs, production platforms and drill rigs, thousands of Kato Engineering alternators are in operation worldwide.

Kato Engineering clients have ultimately included the major international oil and gas companies and many smaller producers too, as well as those who design and manufacture oil and gas equipment. The Kato™ name has become the standard for an engine or turbine-generator package.
