Caterpillar completes first in-hull dual-fuel retrofit

Caterpillar Marine along with Cat dealer Bolier took less than six weeks to complete the operation, which involved retrofitting Cat’s MaK M 43 C diesel engine to a specially-engineered six cylinder M 46 dual fuel platform. The system allows Caterpillar to retrofit inside the hull without having to remove the engine block for machining, modify the vessel’s structure or even dock.

“The benefits of an in hull retrofit for our customers are incredibly significant,” said Axel Hausmann, Caterpillar Marine customer service manager. “In addition to preserving the integrity of the vessel, an in hull retrofit saves the customer time and money in an industry driven by the bottom line.”

The 460mm bore, 610 stroke M 46 dual fuel platform adds 900 kW of power for each of its six cylinders, enabling the Coral Anthelia to switch to LNG when entering Sulphur-regulated ECAs.

“Caterpillar is firmly committed to providing sustainable, flexible solutions that enhance our customers operations. We’re proud of the collaborative effort between Anthony Veder, Cat dealer Bolier and our engineering team to successfully achieve a beneficial industry milestone,” said Karl Vollrath, Caterpillar Marine customer service manager.
