These should be located as far apart from each other as is practicable and preferably on opposite sides of the helideck. Surface units should be equipped with an electronic motion-sensing system capable of measuring or calculating the magnitude and rate of pitch roll and heave at the helideck about the true vertical datum. Details of future movements of units should also be passed to national hydrographic offices so that temporary Notices may be promulgated before a unit gets underway.

The Administration may permit counter-flooding as an operational procedure. The rated capacity for each reeving should be included in the operating manual.

The minimum freeboard of units which cannot cde computed by the normal methods laid down by that Protocol should be determined on the basis of meeting the applicable intact stability, damage stability and structural requirements for transit conditions and drilling operations while afloat.

The sides and backs and, where necessary, the fronts of switchboards should be suitably guarded.

Where the recommendations in table differ from the guidance provided by the Organization30, the provisions of table should be followed. An environmental enclosure for the main switchboard, such as may be provided by a machinery control room situated within the main boundaries of the space, is not to be considered as separating the switchboards from the generators.

The information should be referenced in the operating manual, readily identified, located in an easily accessible place on the unit and be cde at all times.
