Oct 25, 2024 · The aft peak tank is the last tank which acts as the primary structural support towards the aft of the vessel. It lies towards the aft of the aft peak bulkhead. This compartment spans from the after-peak bulkhead to the stern frame and aft end of the ship .

Forward is called Fore peak tank and after one is called After peak tank. Fore Peak Tanks: It is placed forward of the collision bulkhead. Normally it is used for ballast and in some cases for storing Fresh Water.

Dec 5, 2020 · Aft Peak Tank: This compartment extends from after peak bulkhead to the stern frame and aft end of the ship. In this tank also, deep solid floors are fitted at every frame space a/w a heavy centre line girder is fitted right aft as additional strength is required to support the stern which overhangs here and may be subjected to large slamming ...

The aft peak is mainly used as ballast water tank or fresh water tank to adjust the floating state of the ship. The aft peak tank is relatively small, usually as the stern ballast tank, which is combined with the first peak tank to regulate the trim of the hull.

Dec 5, 2020 · Collision bulkhead forms the aft most portion of the Fore peak tank. Usually, Port and Stbd chain lockers are fitted at the aft portion and at higher level. Anchor chains are stowed here and their bitter ends are secured at chain locker bulkhead which can be released in …

An aft peak tank refers to a tank or compartment situated aft of the last watertight transverse bulkhead, which is positioned above the propellers and rudder. This tank is commonly used for storing fresh water or seawater for ballast purposes.

The aft peak tank is the after-most tank on the main hull structure. It is normally used for the storage of fresh water or ballast and it provides a degree of protection to all spaces forward of the aft peak bulkhead.

Distinction is made between the forepeak tank and aft peak tank. The forepeak is the space between the stem and the collision bulkhead. The distance between the stem and the collision bulkhead must be at least 5 per cent of the ships’s length and not more than 8 per cent.

7.1.1 The requirements given in this Section apply to the arrangements of primary structure supporting the peak framing, the scantlings of the bottom structure, framing, aft peak bulkhead, transom and swim end.

The constructing and designing of a ship’s aft end structure is considering lots of factors such as hydrodynamic efficiency, construction simplicity, flow patterns & aesthetics etc. The aft part is characterized by several entities such as an aft peak tank, stern frame, rudder, rudder stock, propeller and its ancillaries.
