Continuous hatchways as trunk ( Regulation 36 ) (IACS interpretation LL.26/Rev.1)

 It is recommended that continuous hatchways may be treated as a trunk in the freeboard computation provided regulation 36 is complied with in all respects.

 The trunk deck stringer referred to in regulation 36(1)(b) may be fitted outboard of the trunk side bulkhead in association with the following:

  • .1 The stringer so formed is to provide a clear walkway of at least 450 mm in width on each side of the ship.

  • .2 The stringer is to be of solid plate efficiently supported and stiffened.

  • .3 The stringer is to be as high above the freeboard deck as practicable. In the freeboard calculation, the trunk height is to be reduced by at least 600 mm or by the actual difference between the top of the trunk and the stringer, whichever is greater.

  • .4 Hatch cover securing appliances are accessible from the stringer or walkway.

  • .5 The breadth of the trunk is to be measured between the trunk side bulkheads.

  • .6 Regulation 36 is complied with in all other respects.
