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 ...
Distressed vessels that request the service of towing vessels have means to make towing as safe as possible. Oil tankers have emergency towing equipment fixed at the forward and aft part of the vessel that will allow to connect the towing line.

The reference load used in the design and testing of the towing winch is twice the static bollard pull. Even if AHTS-vessels are customized for anchor-handling and towing, they can also undertake, for example, ROV (remotely operated underwater vehicle) services, safety/rescue services, and supply duties between mainland and offshore installations.

Some locks have more than one chamber, often of different dimensions. These locks provide the essential infrastructure that allows tows to "stair-step" their way through the system and reach distant inland ports such as Minneapolis, Chicago, and Pittsburgh. The locks can generally be categorized by three different sizes, as expressed by length.
