The ballast system and venting system are designed for the large semi-submersible vessel according to its characteristics. Having decided upon the ballast system of the whole ship, the venting system of the ship is determined as the common venting piping system. Specific measures are proposed to avoid the cumulative water inflow of the relevant tanks caused by the common venting piping system. The safety of the venting system are also analyzed under the worst damage conditions.
