4.1.1 Prior to commencing cargo operations, the
master and the OIM should confirm the loading/unloading plan.
4.1.2 Any circumstance limiting cargo operations
between the OSV and offshore installation (e.g. the visibility of
the deck from the crane control cab, blinding lighting or overboard
discharges from the installation) should be immediately communicated
between the master and the OIM.
4.1.3 The OIM should ensure that a sling of sufficient
length is attached between the crane block and the hook to minimize
danger to cargo handlers and vessel imposed by the block. The crane
block should be marked in such a way that it is visible under all
circumstances of operation.
