All bulk carriers must have ballast tanks of sufficient capacity to allow immersion of the propeller and ensure suitable trim and stability. The ballast conditions of a bulk carrier are as follows: port condition is for trimming/air draught situations, using the additional dedicated cargo ballast holds that are for port use only.

船舶的压载水舱（ballast tank）是放置压载水的船舱，用于调整船舶的重心位置、浮态和稳性。 可解决船舶在航行过程中因油水消耗、重心升高而导致的稳性不足或吃水不适当的问题。

A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural hogging or sagging ...

When tanks are used for BALLAST, it is to add weight to the ship to make her STABLE and sink propeller underwater. Without ballast and cargo, ship will float like a PING PONG ball on water and impossible to manage.

2024年3月16日 · What are ballast tanks and why are they so important on ships? Find out more about different types of ballast tanks provided on ships in this article.

2024年10月25日 · Ballast tanks are vital compartments in a ship filled with water to maintain stability and adjust trim. Different types of ships have various arrangements of ballast tanks, such as double bottom tanks, wing tanks, and peak tanks, serving important roles in buoyancy, protection, and cargo operations.

Ballast tanks can be filled or emptied with water in order to adjust the amount of ballast force. Ballast tanks are usually filled when cargo is being offloaded, and discharged when cargo is being loaded. When ships take in water for ballast in port, they also take in microorganisms e.g. Sulphate reducing bacteria and phytoplankton.

A ballast tank is a compartment within a ship specifically designed to hold water or other heavy objects (called ballast) to adjust the ship’s stability and draft.

Large bulk carrier and oil tanker have several ballast tanks including double bottom tanks, wing tanks as well as forepeak and aft peak tanks. In ship construction, a ballast tank is usually centered at the lowest point of the hull (Fig. 1).
