3.5 Standard loading conditions to be examined

 The standard loading conditions referred to in the text of the present Code are as follows:

  3.5.1.1 For a passenger ship:

• .1 ship in the fully loaded departure condition with full stores and fuel and with the full number of passengers with their luggage;

• .2 ship in the fully loaded arrival condition, with full number of passengers and their luggage but with only 10% stores and fuel remaining;

• .3 ship without cargo, but with full stores and fuel and the full number of passengers and their luggage;

• .4 ship in the same condition as at .3 above with only 10% stores and fuel remaining.

  3.5.1.2 For a cargo ship:

• .1 ship in the fully loaded departure condition, with cargo homogeneously distributed throughout all cargo spaces and with full stores and fuel;

• .2 ship in the fully loaded arrival condition with cargo homogeneously distributed throughout all cargo spaces and with 10% stores and fuel remaining;

• .3 ship in ballast in the departure condition, without cargo but with full stores and fuel;

• .4 ship in ballast in the arrival condition, without cargo and with 10% stores and fuel remaining.

  3.5.1.3 For a cargo ship intended to carry deck cargoes:

• .1 ship in the fully loaded departure condition with cargo homogeneously distributed in the holds and with cargo specified in extension and mass on deck, with full stores and fuel;

• .2 ship in the fully loaded arrival condition with cargo homogeneously distributed in holds and with a cargo specified in extension and mass on deck, with 10% stores and fuel.

  3.5.2.1 For the fully loaded conditions mentioned in 3.5.1.2.1, 3.5.1.2.2, 3.5.1.3.1 and 3.5.1.3.2 if a dry cargo ship has tanks for liquid cargo, the effective deadweight in the loading conditions therein described should be distributed according to two assumptions, i.e. with cargo tanks full, and with cargo tanks empty.

  3.5.2.2 In the conditions mentioned in 3.5.1.1.1, 3.5.1.2.1 and 3.5.1.3.1 it should be assumed that the ship is loaded to its subdivision load line or summer load line or if intended to carry a timber deck cargo, to the summer timber load line with water ballast tanks empty.

  3.5.2.3 If in any loading condition water ballast is necessary, additional diagrams should be calculated taking into account the water ballast. Its quantity and disposition should be stated.

  3.5.2.4 In all cases, the cargo in holds is assumed to be fully homogenous unless this condition is inconsistent with the practical service of the ship.

  3.5.2.5 In all cases, when deck cargo is carried, a realistic stowage mass should be assumed and stated, including the height of the cargo.

  3.5.2.6 A mass of 75 kg should be assumed for each passenger except that this value may be reduced to not less than 60 kg where this can be justified. In addition, the mass and distribution of the luggage should be determined by the Administration.

  3.5.2.7 The height of the centre of gravity for passengers should be assumed equal to:

• .1 1.0 m above deck level for passengers standing upright. Account may be taken, if necessary, of camber and sheer of deck;

• .2 0.30 m above the seat in respect of seated passengers.

  3.5.2.8 Passengers and luggage should be considered to be in the spaces normally at their disposal, when assessing compliance with the criteria given in 3.1.2.1 to 3.1.2.4.

  3.5.2.9 Passengers without luggage should be considered as distributed to produce the most unfavourable combination of passenger heeling moment and/or initial metacentric height, which may be obtained in practice, when assessing compliance with the criteria given in 3.1.2.5 and 3.1.2.6, respectively. In this connection, it is anticipated that a value higher than four persons per square metre will not be necessary.
