HAULING
Warp winch brakes must be disengaged by turning anti-clockwise. Hauling may proceed
once all persons are clear of winches and warp wires.
Once the trawl boards have reached the stern of the vessel they are adjusted so that they
are in the correct position for stowage.
At this stage the winch man gives the order for the crew, students to commence
connecting the drum end chain with the G link to the pennant on the trawl boards this
connects the net to the net drum for hauling the remainder of the net.
Due to the close proximity of the crew and students to wires under tension, and the affect
of swell on the deployed net including the vessel’s yawing motion. Wires may move
horizontally and vertically with extreme force. Extreme caution must be taken during
this operation.
Once the connections are made crew and students are to clear the timber deck. The
winch operator assesses that all crew, students are clear then commences the hauling of
the net onto the net drum.
Note: This may require staff and students to assist in the stowage of the net on to the
net drum until the cod-end comes on board. At this point students must stand clear of the
trawl deck as the cod-end comes up the stern ramp.
Note: When the cod-end comes to the top of the stern ramp there will be amounts of fish
and water trapped causing a free surface affect on the cod-end itself, this and the rolling
motions of the vessel causes the cod-end to slide back and forth uncontrollably. Staff and
students must stand outside the timber deck area while the water drains from the cod-end
and finally becomes stable.
DERRICK OPERATION
To empty the cod-end will require the use of the derrick and a certified lifting strop. The
yellow 3000 kg lifting strop must be placed as close as possible to the catch. By bringing
the strop though itself and on to the derrick hook.
Care must be taken to minimise the amount of slack wire from the derrick. Note: At no
time can the derrick hoot be left unattended to swing freely. The vessel’s course must be
adjusted to minimise rolling and pitching.
Once the derrick hook is attached to the lifting strop lifting may commence. The cod-end
must be lifted just enough to drag it towards the starboard side warp chain as this will
assist in minimising the pendulum effect on the cod-end. It is then lifted from the deck to
allow a crew member to undo the cod-end rope. Once the cod-end rope is undone the
catch will spill onto the deck for sorting.
During the lifting and handling operation all staff and students must be fully aware that the
composition of the catch may consist of large sting rays, sponges, spiny fish, rocks etc.
Students and staff must stand well clear of the cod-end while this operation is taking place.
