1. Shall confirm highest barge level with Crest Provider as the barge is in moored condition then the highest level should less than (3.6 m.) + (1.5 m.) = 5.1 m
2. The procedure shall include emergency plan of how to quick disconnect the gangway when seastate is worse than the design limit
3. The layout shall show movable scaffold to ensure that range of movable scaffold suit with the current gangway layout and operating range
4. Below picture show gangway of GBN WP9. As in the picture end of gangway is located outside the barge for some safety reason and to allow for mooring adjustment. But our layout show that gangway is protrude inside the barge with very low clearance especially for condition C, then shall confirm with Crest Provider that there is no concern with this
