What is a Tugboat?

A tugboat is a vessel designed to maneuver other vessels by pulling or pushing them. This movement can be facilitated via direct contact between the tug and the other vessel or by using tow lines.

How Do Tugboats Work?

Tugboats generally work in one of three ways: direct towing, indirect towing, and pushing. Each is used in specific situations and has its unique advantages. Find out about them below.

Direct Towing

This is the simplest type of towing. Quite simply, a towing line attached to a powerful motor is fastened to the vessel being towed. The tug then pulls the ship through the water. This is often used when the vessel is not able to propel itself. Generally, this type of towing happens at low speeds, typically 4-5 knots, and is governed by the bollard pull of the tug.

Indirect Towing

Indirect towing is another way of maneuvering ships using a tow rope, but it differs considerably from direct towing. In this type of towing, the tow rope is attached to the vessel’s stern, which drags the tug. The tug uses thrust to keep a sheered position in relation to its heading, which allows the drag force to be higher than the bollard pull of the tug. Using this method provides more force when turning or decelerating. It generally happens at speeds of 6 knots or greater.

Pushing

Most commonly used in North America, pushing is exactly what it sounds like. The tugboat pushes the vessel into position, using its impressive power to reposition ships many times larger than itself. Pushing tugs often have an attachment that fits into a specific receptacle of the vessel being pushed, plus tugs of this type are generally built with reinforced hulls.

Types of Tugboats

In general, there are two types of tugboats – escort tugboats and support tugboats. Below, are a little about these two types of Tugboat.

  • Escort Tugboats

Tugs of this type are the most recognizable, as they maneuver and escort vessels in dangerous and coastal waters. The escort tug is required to assist with the steering and stopping of large ships, plus they can also perform routine towing tasks in harbors.

An escort tugboat must have an optimum speed equal to or greater than the maximum speed of the vessel being moved, and it must also be able to carry out duties while moving at these top speeds.

  • Support Tugboats

Support tugboats, as their name suggests, provide support to towing operations. They are primarily used to assist with berthing and unberthing and don’t carry out the heavier work done by escort tugboats – although support tugs are capable of tethered towing of smaller vessels. They can also be used for untethered towing.

It is also possible to find offshore support tugs designed to support offshore operations, such as oil rigs, working in deeper water compared to regular support tugboats. As per regulations, all support tugboats can be used for firefighting purposes.
