Caterpillar Marine has shipped its first Cat 3500 series marine gas engines, destined for and LNG hybrid barge – the world’s first LNG-powered barge in the Port of Hamburg.

Five Cat G3516 marine engines were selected for the Hybrid Port Energy barge. The engine is a spark-ignited, gas engine specially designed to operate in commercial vessel applications. It is compliant with the strict SOLAS requirements and is certified by Bureau Veritas.

Chris Chenette, marine product value manager, Caterpillar Large Power System, said: “The G3516 marine engines represent a pinnacle in efficiency and peak performance, with the capability to handle the dynamic load profiles in typical vessel operations.”

Caterpillar says the base engine is the field-proven, land-based Cat 3516C Island Mode genset engine, which is best known for its best-in-class transient response. The G3516C is a vee-16 configuration, providing 1550 ekW at 1,500 rpm. The fuel system is an inlet fumigated low pressure gas system and is able to run at 100% power with gas qualities down to Methane Nr 70.

“The Cat G3516C is just one product in our comprehensive LNG initiative. We’re pleased to be able to leverage our deep expertise to engineer marine gas engines and deliver high-performing, value-add solutions to our diverse marine customers with varying operational needs,” added Jason Spear, product definition engineer, Caterpillar Marine.
