The net should be inclined upwards and outwards from below the edge of the helicopter deck to a horizontal distance of 1.5 m. Th
7、e outer edge of the safety net or structural protection is not to rise more than 150 mm (6 in.) above the edge of the deck.

8、e Units For personnel protection, a safety net is to be fitted around the helicopter deck with the inboard edge fastened just below the edge of the helicopter deck, except where structural protection exists. The safety net is to extend at least 1.5 m in the horizontal plane and to be arranged so tha
9、t the outboard edge does not exceed the level of the deck and angled so that it has an upward and outward slope of approximately 10. 9.9 Lights (Revise Subparagraph 2/9.9.1, as follows.) 9.9.1 Perimeter Lights (1 October 2015) 9.9.1(a) Vessels. Each helicopter deck is to be fitted with perimeter lig

Those requirements are to be specified and acceptable documentation to verify compliance with those specific requirements is to be submitted to ABS. In the absence of such requirements, omni-directional yellow

These lights are to be positioned around the perimeter of the deck not more than 3 m (9-10“) apart and do not rise more than 150 mm (6 in.) above the level of the deck. 9.9.1(b) Mobile
12、Offshore Drilling Units and other Offshore Units. The perimeter of the helicopter deck is to be fitted with green lights visible omni-directionally from on or above the landing area. These lights are to be above the level of the deck, but not to exceed 250 mm (10 in.) in height for helicopter decks
13、where D-value is greater than 16 m. Where a helicopter deck has a D-value of 16 m or less, the perimeter lights are not to exceed 50 mm (2 in.) above the deck. These lights are to be positioned around the perimeter of the deck not more than 3 m (9-10“) apart, coincident with the perimeter line as pe
14、r 2/9.7.2(i). In the case of square or rectangular decks, at least four lights are to be fitted along each side, including a light at each corner. Flush fitting lights may be used at the inboard edge of the helicopter deck (150 limited obstacle sector origin) where there is a need to move a helicopter or large equipment off the helicopter deck. 2 ABSGUIDE FOR THE CLASS NOTATION HELICOPTER DECKS AND FACILITIES (HELIDK AND HELIDK(SRF) .2008
