High-speed machine solutions for operation and dock tugboats

Port farms and terminal tugboats run an average of 1,000 – 3,000 hours per year, however, about 80% of the time the engines are operated under 20% load. Therefore, one criterion for choosing the best engine for your tug is: power load sharing. In the 1980s, about 70% of tugboats were equipped with medium speed engines. Today, nearly 90% of tugboats in ports and terminals under construction use high-speed engines.

High-speed engine for port and salvage tugboats

1:Acceleration function
The high-speed engine has a wider operating range, from idle to full load, more powerful acceleration, better performance and operability. Acceleration time and operating speed range-maximum power comparison (0-100%).

2:Size and weight
High-speed engines are usually one-third the size and weight of medium-speed engines, and high-speed engines are cheaper and easier to install.

3:Fuel consumption
When the engine load is 50% ~ 70% and above, the medium-speed engine has lower fuel consumption than the high-speed engine.

4:Operating cost
Related operating costs for high-speed and medium-speed engines over 15 years, it is clear that high-speed engines have lower operating costs, with savings of 10% to 12%
