e.
Using powered anchor winch, lower the stern anchor to the seabottom. Do not "free fall” the anchor
because the anchor cable will tangle.
f.
Tug maneuvers barge downcurrent to anchoring position for downcurrent stern anchor, as barge pays out
anchor cable.
g.
When tug has placed barge in position for downcurrent stern anchor, and barge has payed out about 550
feet of cable on upcurrent stern anchor, barge lowers downcurrent stern anchor to seabottom.
h.
With both stern anchors positioned, tug moves barge out to desired final anchored position. Barge pays
out cable on downcurrent stern anchor and pulls in cable on upcurrent stern anchor.
i.
When tug has barge in desired final anchored position, it holds barge in this position. The barge, using its
bow crane, passes bow upcurrent anchor to auxiliary vessel. The auxiliary vessel, as barge pays out
anchor cable, takes upcurrent bow anchor out to its anchor position and drops it.
k.
Using anchor winches, barge crewmembers set these three anchors. When these anchors are set and
holding, tug casts off, moves away from barge, and stands by.
I.
The barge, using bow crane, passes downcurrent bow anchor to auxiliary vessel and as barge pays out
anchor cable, auxiliary vessel carries anchor to its anchor position and drops it. Barge uses anchor winch
to set this anchor.
m.
When all anchors are set, bargemaster takes bearings on several landmarks and checks that anchors are
holding.
n.
When bargemaster determines that anchors are holding, the winches are turned off, the electric brakes
are automatically set, and the mechanical brakes are set to backup electrical brake.
o.
Tug is released from its standby position.
16-15 Modified anchoring with four anchors. If water is too shallow for tug, with barge on its hip, to move in close to
shore to position barge for dropping stern anchors, the normal anchoring method is reversed. In this method, tug
positions barge for dropping bow anchors first and uses an auxiliary vessel to position inshore anchors.
a.
First two steps are the same as in normal anchoring
b.
If water depth does NOT permit tug to move in close to shore, it moves barge over position for upcurrent
bow anchor. Barge lowers (using power, not a free fall) bow anchor to the seabottom. As tug maneuvers
barge downcurrent to anchoring position for bow downcurrent anchor, barge pays out anchor cable.
c.
When tug places barge over position for downcurrent bow anchor, barge lowers that anchor to
seabottom.
d.
With both offshore anchors positioned, tug moves barge to its desired final position and holds barge in
this position.
e.
The barge passes stern upcurrent anchor to auxiliary vessel. The auxiliary vessel, as barge pays out
anchor cable, takes upcurrent stern anchor to its desired position and drops it.
f.
Using anchor winches, barge crewmembers set these three anchors. When these anchors are set, tug
casts off, moves away from barge, and stands by.
g.
Barge passes downcurrent stern anchor to auxiliary vessel, and, while barge pays out anchor cable,
vessel carries anchor to its desired position and drops it. Barge uses anchor winch to set this anchor.
h.
When all anchors are set, bargemaster takes bearings on several landmarks and checks that anchors are
holding.
i.
When bargemaster determines that anchors are holding, winches are turned off, electric brakes
automatically set, and mechanical brakes are set to backup electrical brake.
j.
Tug is released from its standby position.
