Machinery space ventilation

Machinery space ventilation
E.5.1 The ventilation systems for machinery spaces of category A shall be separated from the ventilation
systems serving other spaces and shall be in general of the supply type. Other modes of operation
may be applied upon special approval.
E.5.2 Machinery spaces of category A shall be adequately ventilated so as to ensure that when machinery
or boilers therein are operating at full power in all weather conditions including heavy weather, an
adequate supply of air is maintained to the spaces for the safety and comfort of personnel and the operation
of the machinery. Any other machinery space shall be adequately ventilated appropriate for the purpose
of that machinery space.
E.5.3 In general, ventilators necessary to continuously supply the machinery space shall have
coamings of sufficient height to comply with LLC 1966 as amended 1988, Regulation 19(3), without having
to fit weathertight closing appliances (see also D.3.2). However, where due to ship size and arrangement
this is not practicable, lesser heights for machinery space coamings, fitted with weathertight closing
appliances in accordance with LLC 1966 as amended 1988, Regulation 19(4), may be permitted by the
Administration in combination with other suitable arrangements to ensure an uninterrupted, adequate
supply of ventilation to these spaces. The machinery spaces are those defined in SOLAS Regulation II-
1/Reg. 3.16.
