Machinery space and emergency generator room ventilator coaming heights (Regulations 17(2) , 19(3) and 19(4) ) (IACS interpretation LL.58)

 Regulation 17(2) requires that the coamings of machinery space ventilators situated in exposed positions on the freeboard and superstructure decks shall be as high above the deck as is reasonable and practicable.

 In general, ventilators necessary to continuously supply the machinery space and, on demand, immediately supply the emergency generator room should have coamings which comply with regulation 19(3), without having to fit weathertight closing appliances.

 However, where due to ship size and arrangement this is not practicable, lesser heights for machinery space and emergency generator room ventilator coamings may be accepted with the provision of weathertight closing appliances in accordance with regulation 19(4) in combination with other suitable arrangements to ensure an uninterrupted, adequate supply of ventilation to these spaces.
