The invention provides a method for preventing influence on release of a ship lifeboat, which specifically comprises the following steps:
s1, determining a tube distribution inhibition area I affecting the jettisoning in a design drawing according to the arrangement position of the lifeboats in a ship design stage.
The pipe distribution prohibition area I is a ship body area between a first inclined line 2 and a second inclined line 3 which respectively take the bow and the stern of the lifeboat 1 as a starting point, and the first inclined line 2 and the second inclined line 3 are straight lines which are perpendicular to the water surface when the ship 4 leans forward and backward by an angle A degrees respectively.
The lifeboat 1 is arranged on a main deck 5 above the nacelle.
S2, according to the determined tube distribution prohibition area I, the installation position of the outer tube 6 is drawn in a design drawing, and the outer tube 6 is installed at any position outside the tube distribution prohibition area I.
Preferably, the outboard tube 6 is mountable in a hull area below the waterline outside of the tube laying inhibition area I, i.e., in area iii; but also can be arranged in the area of the ship body above the water line, namely the area II, which is outside the pipe distribution prohibition area I.
S3, in the ship building stage, the outboard discharge pipe 6 is installed on the corresponding section according to the installation position of the outboard discharge pipe 6 in the design drawing, and the cooling water pump 9 and the outboard discharge valve 7 are installed on the outboard discharge pipe 6.
