AdequateДrainage to the bilge is provided where a ceiling covers this space. On many vessels a sloping margin plate is fitted and a natural bilge isДЇormed with the suctions conveniently located within this recess. However, where a ship has a single hold which exceedsДЈ3.5m in length suctions are also arranged in the forward half length of the In service, and the suctions will therefore be placed in the after part of theД¬ompartment. Generally vessels are designed to have a moderate trim by the stern Necessary to fit port and starboard suctions in other than very narrow Piping arrangements may also be fitted in oil tankersДЇor tank washing and for introducing inert gas into the tanks.ДЄs the vessel is to be pumped out when listed it is Where required the liquid cargo loading and discharging, pumping and Installation of the statutory bilge drainage, ballasting, general services, and

In the construction of a merchant ship the shipbuilder is concerned with the In steam ships, or the main cooling water pump in motor ships.

An emergency bilge suction is also provided in machinery spaces,ДЄnd may be connected to the main circulating water pump (for condenser) Is from the main bilge line and the other from an independent power driven Pumped out through two suctions under the above conditions. The arrangements in the machinery space are such that this space may be May be pumped out following a casualty under all practical conditions The case of passenger ships, each compartment or section of a compartment Pumped out when the vessel has a list of up to 5В°, and is on an even keel. The results showed the stress that occurred in the ship model without using margin plate was better to withstand the transverse and longitudinal strength of the ship compared to the ship model with the margin plate.Bilge systems -Pumping and piping arrangements for modern cargo shipsДЄll cargo ships are provided with pumping and piping arrangements so thatДЄny watertight compartment or watertight section of a compartment can be So that the ship model with a margin plate sagging condition was 23,189 (N / mm2) and hagging condition was -20,585 (N / mm2). The longitudinal strength of the ship was also a varied of every increase of 0.2 x maximum moment with a review point of meeting between bottom plate and bilga plate for the ship model without margin plates using the Multi Point Constraint (MPC) method looking for results in sagging conditions of 12,443 (N / mm2) and the hogging condition was -11.045 (N / mm2) at 100% x maximum moment load conditions. The difference in stress due to the effect of deck loads was an average of 13.49% while the effect of side loads was on average 8.74%. The results of the comparison due to bottom load averaged 15.82%. The result shows if the loadvariatied 0.2 x maximum load on the calculation of the transverse strength of the ship, the stress value on the ship model with a margin plate was 9.6242 (N/mm 2) and on the ship model without margin plate was 8.4739 (N/mm 2) under conditions 100%. The analysis was carried out by using Finite Element Method so-called ANSYS TM. The ship is currently built with an inner bottom plate continuously from the left side to the right side of the ship.This study aims to determine the transversal and longitudinal strength ratio of ships with and without margin plate.

Lately the bottom construction of the ship tends not to use the margin plate. Margin plate is a part of bottom construction that joint the floor and frame construction of the ship, so the inner bottom plate will be installed cut off on the margin plate.
