16.2.1 The maximum expected sea state is to be defined for surface and near surface
operation, taking account of the expected areas of operation and noting possible
restrictions on diving due to depth limitations.
16.2.2 The maximum expected wave height is to be defined for normal and abnormal surface
operating conditions. Access openings, snort induction and exhaust openings are to
be suitably located and adequately protected against ingress from the combination of
wave height and submarine motion.
16.2.3 The wave loads and the number of waves return period expected for normal and abnormal
operating conditions are to be determined.
16.2.4 The submarine, systems, equipment and components that are required to operate within
an exposed environment in normal, abnormal and emergency operating conditions are to
be identified. They shall be able to operate with defined levels of wave impact
loading or be fitted with suitable protection measures, e.g. casings, masts, bridge
fin, control surfaces, communication masts, navigation lights, etc.
16.2.5 The maximum expected wave height is to be defined for emergency surface operating
conditions.
