Naseeb Maritime also provides Tug boats for the berthing and un-berthing of ships. Once the ship is close enough for mooring ropes to be passed, one or other of the tugs on the ships side to relive the pressure on mooring lines until all the ropes are secured. For relatively large ships, the procedure for leaving a berth is a very much the reverse of that used for berthing. Once the ship has been moved off the berth sufficiently, the head tug will impart some forward motion, towing the ship in the direction she is to head.
