anchor weight, either a ship with a hoisting crane or U-frame or a ship with a removable railing
should be chartered. For comfortable deployment a day with small waves is best waited for.
The procedure in Figure 5.8.8 is suggested for a small vessel with a hoisting crane or
removable railing in the front. Users should adapt the procedure to size and outfit of their ship
and according to their own experience. Before the actual deployment lay out the mooring line
on deck and connect the ends to the anchor weight and buoy using the shackles and split pins. If
you use the 8-shaped pack with tiers, remove the tiers just before launching. Never stand inside
the loops of the mooring line or between the mooring line and the ship sides. Hoist the anchor
weight on the side of the ship and hang it overboard on a rope or push it towards the removable
railing but not over. Release the anchor weight from the hoisting crane and leave it hanging
overboard. Once you are at the intended location steer the ship in reverse backing up against the
current. This manoeuvre will keep the mooring line out of the screw propeller. Deploy the buoy
by hoisting or pushing it overboard. If you hoist the buoy, use an extra piece of rope to keep the
crane hook at a distance from the antennas. To release, cut the rope. The buoy may be safely
dropped from a height of 2 m. Give the line sufficient slack before dropping the buoy, so that
the latter will not be jerked upside down. Keep the line slack, running out the line loop by loop
while the buoy drifts away from the ship. Finally, cut the rope that carries the anchor weight or
push the anchor weight overboard. Do not use your hands, you may get entangled. Continue to
back up until the ship has gained enough distance to steer clear of the buoy and mooring line.
