Bring a 200-metre ship alongside the berth using two tugs: push both to walk the vessel in bodily, apply asymmetric thrust to swing the bow or stern, and land her gently without sheering off the dolphins. Covers tug-assist terminology (push, pull, walk, swim), the harbour pilot's helm and engine telegraph orders during a tug-assisted docking, and the mooring line sequence for a large deep-draft vessel.
Based on the actual techniques used by licensed harbour pilots. Develops the spatial thinking required to control a large vessel in a confined berth — the highest-skilled single task in commercial maritime operations.
