Surface Cleanliness of FJC on Pipelaying Barge (DNV-RP-F102)
Surface Cleanliness of FJC on Pipelaying Barge (DNV-RP-F102)
(OP)
DNV-RP-F102 calls the Field Joint Coating (FJC) applicable on the steel cleanliness of Sa2 1/2 treated by blast cleaning. In offshore FJC is applied on the pipelaying barge, and the field joints are not blast cleaned (there is not blasting station on pipelaying barge, and the field joint are cleaned by wire brush/flame).
The question this is, how FJC as per F102 should be applied on pipelaying barge considering required cleanliness (treated by blasting)?

'Bristle blasting' is a very good power tool cleaning method.
