HULL
A hull is the watert ight body of a ship. Above the hul l is the superstructure and/ or deckhouse
where present . The l ine where the hul l meets the water surface is cal led waterl ine. The
structure of hul l var ies depending on the ship type. In this document, wi ll explain about the
calculation of frame spacing, watertight bulkhead, double bott om and the tank summary that we
have done before. Al l of those i tems, wi ll be appropriate wi th recommended class rule,
Germanischer Lloyd and Guidelines 2011.
The purpose of this document is to determining and calculate the hull structure such as the main
frame spacing, watert ight bulkhead, double bottom and the tanks.

Irrespective of the ship's deadweight, the length of cargo tanks of oil and product tankers
measured between oil t ight bulkheads is not to exceed 10 m or the values l isted in Table
24.1, whichever is greater.
Where the tank length exceeds 0,1 L and/ or the tank breadth exceeds 0,6 B calculations
must be carried out in accordance with Section 12, C.1. to examine if the motions of liquids

Double hull requirements for oil tankers of 5 000 tdw & above (GL Part 1 Chapter 1 Section
24 A. 3.2.1)
The entire cargo tank length is to be protected by a double side (wing tanks or spaces) and
double bottom tanks or spaces as outl ined in the fol lowing paragraphs.
Wing tanks or spaces are to extend ei ther for the ful l depth of the ship's side or from the
top of the double bottom to the uppermost deck, disregarding a roundedgunwale where
f it ted. They are to be arranged such that the cargo tanks are located inboard of the
moulded line of the side shell plating, nowhere less than the distance w which is measuredat every crosssection at right angles to the side shell .

Defining this bulkhead is depending on main engine dimension and another equipment will be
added like the transmision system, auxiliary engine, and another. And the in this design engine
room bulkhead will be taken 26 frame spacing, and right close to frame number 35.
The cargo holds located from frame number 45 - 163, where in the rest frame is used to be pumproom in frame number 35 - 39, slop tank frame number 39 - 45 and cofferdam frame number 163 -
165. For the cargo holds, amount designing 6 cargo holds.
According to GL 2011 section 24.A.3.2.3 Double bottom, at any cross-section the depth of each
double bottom tank or space is to be such that the distance h between the bottom of the cargo
tanks and moulded line of the bottom shell plating measured at right angles so the bottom shell
plating is not less than :
