The global growth in marine transport and the accompanying increase in the volume and complexity of harbor operations have expanded the tug sector in recent years. Simultaneously, the general increase in vessel size, such as that experienced within the container and tanker sectors, has prompted the development of larger, more powerful tugs.
Modern tugs require cost-efficient propulsion systems (with low first-costs), while the nature of harbor operations demands that engines possess great adaptability to low-load operation. Harbors are also environmentally sensitive areas and, accordingly, emission requirements are strict in terms of NOx and particulate matter.
The operation profile of a tug is pretty much as a “sleeping bear” – many hours of standby just waiting and then full power on all engines. It requires a lot of the engine to be able to handle those load challenges a tug is requiring. All our engines are equipped with jetassist which boost the turbocharger speed if sudden load peaks occur resulting in rapid and smoke free load increase.
Our engines tackle emissions by using exhaust-gas-cleaning systems such as SCR (Selective Catalytic Reduction) to minimize NOx. We also have a four-stroke engine portfolio that includes a range of dual-fuel engines capable of running on gas, as well as HFO, to ensure compliance with IMO Tier III and sulfur emission regulations.
We offer a comprehensive, service network in the form of MAN PrimeServ. PrimeServ is a service organization with a global reach and contactable 24/7 to maximize engine availability. As a part of its service offerings, PrimeServ offers optional online services for optimized maintenance planning.
