A good manoeuvring performance of ships may result in a significant reduction of operational cost.

The reason for this is because of the minimized added resistance when there is a less required steering, lesser turn-around of harbour and a reduced tug assistance.

Manoeuvring is an important marine operation. It is done when a vessel or ship enters or exits a country’s coastal waters, trying to cross many vessels along the way, or when approaching or leaving from a port’s bunk or jetty. Not only at a point when a ship arrives or departs a pier that it needs to do manoeuvring. But, also while it is going to cross traffic zones and canals. This procedure basically needs a large manpower and that all automatic systems are diverted to manual control in order to obtain a full control of the vessel.

Every ship’s manoeuvring conduct can be assessed through the following control system:

  • controllability
  • course stability
  • turning ability
  • dynamic tracking capacity or dynamic positioning
  • harbour manoeuvrability

In addition, the elements of the ship like heel angles are also crucial during manoeuvres for the ship’s safe operation.

Together with the other elements such as the ship’s propulsion, equipment, resistance, framework design and seakeeping, seafarers must as well know how it is immensely important to understand the vessel’s manoeuvrability factor or operation.

By nature, every ship has to withstand the long navigations along with the disparate conditions of the weather.  Because of this, it is relevant that a ship’s daily affairs or operation are not arbitrated on the following:

  • Turning or changing course about an interference such as a large body of land or any other marine vehicle
  • Circumnavigating about a wanted point or location of interest
  • Surging, blocking, and increasing speed
  • Either keeping or differing direction course
  • maintaining a desired path or course
  • To immediately drift or change direction about an object such as landform, iceberg, ship, etc, without yielding much time

The manoeuvring process is thought-out to be a very critical moment that every ship or vessel encounters during a voyage. In fact, most incidents like grounding and collisions often occur during the manoeuvring of ships or vessels.

Every time a ship enters or departs a port, a ship pilot, marine or maritime pilot’s attention is essentially needed. He is the one responsible for manoeuvring the vessel from an entry point recognized as the pilot point, up to the harbor or on the other way.



More Facts about Manoeuvering 

  • Understanding the outcome of weather particularly the tide and wind, also the vessel trim condition, machinery, draft, and freeboard, etc. is very crucial before a manoeuvering procedure starts.
  • The manoeuvering characteristics include turning or passing through, course-keeping, yaw-checking, and the ship’s stopping capabilities….
