    Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft.It is defined as the force (usually in tonnes-force or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient ...

    A tugboat is typically rated by its engine's power output and its overall bollard pull. The largest commercial harbour tugboats in the 2000s–2010s, used for towing container ships or similar, had around 60 to 65 short tons-force (530–580 kN) of bollard pull, which is described as 15 short tons-force (130 kN) above "normal" tugboats.

    The propellers can deliver a combined bollard pull of 480 tons with 18-43 MW (25,000 shaft horsepower) [totals: 55.3 MW (75,000 shp)]. This amounts to a maximum speed of 22 knots (41 km/h; 25 mph) on open water, full speed [ clarification needed ] of 19 knots (35 km/h; 22 mph), and an average speed of 3 knots (5.6 km/h; 3.5 mph) while ...

    The Glen-class tugs which the NLTs are replacing have a bollard pull of 18 metric tons (18 long tons; 20 short tons) and 850 horsepower (630 kW) on each side. The NLTs have much increased power at 60 metric tons (59 long tons; 66 short tons) of bollard pull and Azimuth stern drive propulsion with 4,988 horsepower (3,720 kW) per side. [1]

    Each of the engines are rated at 1,810 horsepower (1,349 Kw). [8] The ships are capable of more than 12 knots when running without a tow. Their engines generate 40 short tons of bollard pull. [7] [9] The Rainier class is the first tug in the Navy to meet the EPA Tier 4 emission standards. [6] Their fuel tanks have a capacity of 26,000 US ...
