Anyone observing a large ship arriving at or departing from a port may notice the presence of smaller vessels accompanying its movement. These are tugboats, vessels designed to assist ships during maneuvers that require strength, precision, and control.
Equipped with powerful engines and high maneuverability, tugboats can push or pull large vessels during entry, exit, and berthing operations. Their role is especially important in confined areas, such as access channels, turning basins, and areas near berths.
When do tugboats come into action?
The use of tugboats depends on the characteristics of each operation. This means that not every ship arriving at a port necessarily needs to use a tugboat. The need for support is defined according to factors such as the vessel's size and type, wind and current conditions, the characteristics of the channel and berth, and the applicable rules for the operation. When necessary, tugboats can operate during different stages of the maneuver. Upon arrival, they assist the ship in approaching and positioning alongside the quay. Upon departure, they can help move the vessel away from the berth and guide it to a more open navigation area.
A single operation can also involve two or more tugboats operating simultaneously. The number used varies according to the ship's characteristics and the maneuver's conditions. In certain situations, the support of more than one vessel allows for greater control over the ship's movements.
How does it work in practice?
An example is the Port of Santos, one of the main port complexes in the country. There, specialized companies provide tugging services to assist in ship maneuvers. During the arrival of a large vessel, for example, the ship travels through the access channel until it approaches the berthing area. In the final stage of the maneuver, when it is necessary to reduce speed, change direction, and position the vessel alongside the quay, tugboats can be called upon to assist in controlling these movements.
Depending on the operation, more than one tugboat can operate at the same time, each contributing to control a specific movement of the vessel. The work is coordinated with the ship's crew and other professionals involved in the operation.
Safety in port operations
The role of tugboats becomes even more important when navigation conditions make the maneuver more complex. Strong winds and sea currents, for example, can influence the displacement of a large vessel. In these situations, the strength and maneuverability of tugboats help maintain control of the ship and reduce the risk of contact with other vessels, port structures, and nearby installations. Operations also rely on the work of pilots, professionals specialized in local navigation, who guide the conduct of ships considering the specific characteristics of each port.
In addition to berthing and unberthing operations, tugboats can provide assistance in situations requiring additional support, such as propulsion failures or other occurrences that compromise a vessel's ability to move independently.
Despite being smaller than the ships they assist, tugboats play an important role in daily port routines. The operation of these vessels allows maneuvers to be carried out with greater control and safety, contributing to the movement of ships of different sizes.
