    IMO Ship Type 1
    is a chemical tanker intended for the transportation of products considered to present the greatest overall hazard. The quantity of cargo required to be carried in a Type 1 ship should not exceed 1,250 m3 in any one tank
    IMO Ship Type 2
    is intended to transport products with appreciably severe environmental and safety hazards which require significant preventive measures to preclude escape of such cargo. The quantity of cargo required to be carried in a Type 2 ship should not exceed 3000 m3 in any one tank
    IMO Ship Type 3
    is a chemical tanker intended to transport products with sufficiently severe environmental and safety hazards. These products require a moderate degree of containment to increase survival capability in a damaged condition. There is no filling restriction for chemicals assigned to Ship Type 3

    Cargo Tank Location
    2.6.1 Cargo tanks shall be located at the following distances inboard:
    Type 1 ships: from the side shell plating, not less than the transverse extent of damage specified in 2.5.1.1.2, (B/5 or 11.5m whichever is less), and from the moulded line of the bottom shell plating at centerline, not less than the vertical extent of damage specified in 2.5.1.2.3, (B/15 or 6 m whichever is less), and nowhere less than 760 mm from the shell plating. This requirement does not apply to the tanks for diluted slops arising from tank washing.

    .2 Type 2 ships: from the moulded line of the bottom shell plating at centerline, not less than the vertical extent of damage specified in 2.5.1.2.3, (B/15 or 6 m whichever is less), and nowhere less than 760 mm from the shell plating. This requirement does not apply to the tanks for diluted slops arising from tank washing.


    .3 Type 3 ships: no requirement"

            The International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) applies to gas carriers constructed on or after1 July 1986. Gas carriers constructed before that date should comply with the requirements of the Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk or the Code for Existing Ships Carrying Liquefied Gases in Bulk.


            Gas carriers are classified into three main types based on the hazardous nature of cargo:
            1G : designed for most hazardous cargo
            2G & 2PG: designed for lesser degree of hazard (mostly LPG and LNG)
            3G : designed for least degree of hazard

                See the no.of strands & wire in each strand..for ex : 6x24,6x37,also measure dia of wire rope and from dia & construction you can find the SWL

                  D*D*8=SWL. D IN INCHES AND SWL IN TON. D IS THE DIA.

                          Q. 10) What are the test for container ? what is racking stress ?

                            X
                            1

                            Container placed on four supports located exactly on the four bottom corner castings. Now the so mentioned weight is applied to rack it transversely (i.e., the bottom will be fixed and only the top part will be shifted longitudinally bending the corner castings and vertical members) and check for its integrity. The value mentioned in the safety approval plate is that for the transverse test and not for the longitudinal. Hope i'm right!!!  Ref- CSC annex-2
