Stability is the science of calculating the ability of ship to remain upright in all Conditions of weather and seas. One of the important aspects of determining such stability is the knowledge of areas and the volumes of the ship. Even though practical stability calculations
Why the vessel has to be inclined ??? To obtain the metacentric height it is necessary to determine the position of the centre of gravity `G’. This calculation consists of two parts. a) The first is the finding of the height of the metacentre ‘M’
Basic Understanding In very broad terms, the ability of a vessel to maintain the true vertical can be termed as the measure of her Transverse Stability. Transverse Stability is the ability of the vessel to return to vertical when she has been heeled. The heeling
Theory 1. Grounding is similar to dry-docking, but with certain modifications as follows : a. Ship may have any displacement. b. Trim may be by the stern or by the head or the ship may be on even keel. c. The point of contact on
Theory 1. During dry docking the ship shall be in as light a condition as possible. 2. It shall be trimmed by the stern. 3. Minimum trim required for safe and convenient docking is prescribed by the dock authorities. 4. Chief Officer shall ensure that
What is Bilging Bilging is said to occur when ingress of water takes place into the vessel from a point below the waterline, such that the water is free to flow in and out of the vessel. If the water enters the vessel from above
Reg. 25 Ch II – 1 of SOLAS deals with subdivision & damage stability of Cargo Ships. Reg.25-8: Master shall be supplied with such reliable information so as to have raid & simple means to obtain accurate guidance as to stability under varying conditions of
When a ship with negative initial metacentric height is inclined to a small angle, the righting lever is negative, resulting in a capsizing moment. This effect is shown in Figure and it can be seen that the ship will tend to heel still further. At
APPLICATION a) The Code applies to cargo ships, timber carriers, grain carriers, container ships, cargo ships carrying containers on deck, passenger ships, fishing vessels, special purpose ships, offshore supply vessels, mobile offshore drilling units, pontoons and dynamically supported craft. b) Special purpose ship means a
