Caterpillar Marine Power Systems is to provide four MaK engines - two 6 M 25 C and two 9 M 25 C - for the diesel electric system for an offshore supply newbuild, ordered from Astilleros Gondan in Spain. The 9 M 25 C engines are rated at 3,000kW at 750rpm, and the 6 M 25 C engines will develop 2,000kW @ 750rpm. All four engines feature a new air injection system, designed to ensure load response remains in a low rpm range. Compressed air is injected after the turbocharger, causing what the company describes as a "diffuser effect" that supports the turbocharger performance. Andreas Banck, supervisor diesel engine test team says: "Compared to Jet Assist offered by the competitors our system will not put any extra load on the turbocharger."
