2.3 Shipside discharges below the freeboard deck

  2.3.1 The provision and control of valves fitted to discharges led through the shell from spaces below the freeboard deck or from within the superstructures and deckhouses on the freeboard deck fitted with weathertight doors should comply with the requirements of the relevant regulation of the International Convention on Load Lines in force, except that the choice of valves should be limited to:

  • .1 one automatic non-return valve with a positive means of closing from above the freeboard deck; or

  • .2 where the vertical distance from the summer load waterline to the inboard end of the discharge pipe exceeds 0.01L, two automatic non-return valves without positive means of closing, provided that the inboard valve is always accessible for examination under service conditions.

  2.3.2 For the purpose of this chapter “summer load waterline” and “freeboard deck”, have the meanings defined in the International Convention on Load Lines in force.

  2.3.3 The automatic non-return valves referred to in 2.3.1.1 and 2.3.1.2 should be fully effective in preventing admission of water into the ship, taking into account the sinkage, trim and heel in survival requirements in 2.9 and should comply with recognized standards.
