7 Details of construction

  7.1 Local strengthening of the walls and ceilings in the cabin and corridors should be provided for mounting heavy items of furniture such as beds, cupboards, railings, etc., if necessary.

  7.2 On all ro-ro passenger ships, the corridor panel system should be capable of supporting the evenly distributed load as required by SOLAS regulation II-2/28-1.

  7.3 Draught stops in ceiling and lining voids should be erected in accordance with the relevant regulations in SOLAS chapter II-2.

  7.4 The method of connecting the corridor panels to cabin unit panels (if these panels are separate) needs special consideration where the corridor to cabin doors could be connected to both panel structures and the corridor panels may be partially supported by adjacent cabin construction (see figures 3.1-1, 3.1-2, 3.2-1, 3.2-2, 4.1-1, 4.1-2, 7.4-1 and 7.4-2).

  7.5 Special attention should be given to the joints of the structural components (such as ceilings, bulkheads, linings, bathroom units) from different manufacturers in order to maintain the required fire integrity and, where required, the continuous "B" class construction (see figure 3.1-3).
