Caterpillar introduces marine hybrid system

Caterpillar Marine Power Systems announces the introduction of a complete hybrid propulsion package applicable to all engine platforms. Developed with electrical specialists Aspin Kemp & Associates (AKA), the Cat® Powered Marine Hybrid System utilizes AKA’s XeroPoint Hybrid marine propulsion system and provides fuel savings of up to 25 percent. It also provides emission reductions. A recent California Air Resources Board study found a 73 percent reduction in PM, 50 percent reduction in NOx and 26 percent reduction in CO2 from a hybrid system in Los Angeles/Long Beach.

The Cat hybrid system optimizes the use of currently available components and has the potential to increase operating efficiencies as well as meet or exceed increasingly stringent environmental requirements. The system is completely customizable to specific customer specifications.

The Cat Powered Marine Hybrid System is currently being utilized in the global tug and salvage market. The RT Adriaan, a hybrid tug built by Kotug, features three Cat 3512 marine engines as well as the new hybrid system. Kotug has also elected to install the system on two new tugs currently under construction at a Damen shipyard. Two more hybrid-ready tugs are currently under construction at Cheoy Lee Shipyard.
