Before revision: We can consider three configurations Vessels making way, fast approach (1) Mother vessel stopped (2) Vessels making way, tactful approach (3) Approaching with a tug assistance (4) The table below show the required manoeuvre regarding the operation for a few vessels+ Table Pilot Boat Supply Vessel Bunker Barge Open-sea vessel Pilot Boat 3 1 1 1 Supply Vessel 1 3 3 3 Bunker Barge 1 3 2 2 Open-sea Vessel 1 3 2 3 Vessels making way, fast approach The small pilot boat considers this LNG as a stable reference This manoeuvre is designed for a vessel with a high maneuverability which approaches such a big vessel that it can be considered as a reference on its own.
