Performance criteria

You must be able to:

P1 complete safety check before using shore mooring equipment in accordance with approved procedures and practices
P2 ensure that shore mooring equipment is operated correctly according to agreed mooring scheme
P3 monitor the vessel's mooring operation
P4 obtain all relevant vessel information
P5 analyse information and ensure that the vessel is positioned within prescribed parameters
P6 ensure the vessel is correctly positioned alongside cargo transfer equipment and you can safely make the connections to transfer the cargo
P7 take the appropriate action if the vessel moves out of prescribed parameters
P8 ensure the vessels mooring pattern meets the prescribed plan for the vessel and berth
P9 ensure that the correct mooring equipment is used in accordance with the mooring scheme
P10 ensure that the agreed mooring plan is implemented
P11 ensure that vessel and shore's emergency plans and procedures are defined and agreed
