Mooring and Anchoring (MIDTERM) Flashcards
provides storage for the chain cable and is situated under the deck with a pipe connection (Spurling pipe)to the anchor windlass
chain locker
incorporates an arrangement to facilitate drainage, with the chain cable stowed on a grating
Chain locker
is used to tightly secure the anchor when in the stowed position
anchor lashing
to be well placed inside the hawse pipe
Anchor
are to be well placed to insert the pins
Bow stoppers
taken and tightened with bottle screw slips.
Additional wire lashings
taking the control of the vessel at the bridge, accompanied by the third officer
Master
at the ship’s bow to command and guide the forward station
Chief Officer
at the aft to command the aft station
second officer
will be asked by the second or chief officer to assist in the berthing procedure
Deck crew members
can be asked to carry out the job of a look-out by the master whenever necessary
Additional deck crew members
would generally assist the chief officer and is in-charge of preparing mooring lines for berthing
Bosun
typically run through the bull nose on the bow and run forward down the dock, leading ahead of the ship
Bow lines
When backed against, these lines will help to bring the ship in toward the dock.
Bow lines
usually run through the centerline chock, and run aft of the ship.
Stern lines
When pulled forward against, these lines help to bring the ship alongside the dock
Stern lines
usually put out from the bow or stern, and occasionally amidships, these lines hold the ship alongside the dock
Breast lines
They do not prevent surging in any direction other than away from the dock
Breast lines
are usually the last lines sent out and the first brought in.
Breast lines
From the after section of the bow leading forward
Forward bow spring
these help to prevent the ship from surging backward should a wake or wind force the ship astern
Forward bow spring
When backed against, they will help to pull the ship in to the dock
Forward bow spring
From the bow leading aft
After bow spring
, these lines prevent the ship from surging forward should a ship’s wake or wind force the ship ahead
After bow spring
when run forward against, they will help to kick the stern out away from the dock
After bow spring
the lines run from the quarter aft and prevent the ship from surging forward.
After quarter Spring
When pulled forward against, these lines help to pull the ship in toward the dock
After quarter Spring
These lines run from the stern forward, and prevent the ship from surging aft
Forward Quarter Spring
When pulled astern against, these lines help to push the bow out away from the dock
Forward Quarter Spring
safety measures to be taken when handling mooring ropes and wires:
Avoid Mixed Mooring
Consider Weather Condition
Have knowledge of Snap Back Zone and Rope Bight
Check All the Mooring Equipment
Check the Tail of Mooring Line
is probably one of the most important knots you can learn, whether it be for diving, climbing, sailing, or any other outdoor activity
Bowline
It is a knot which is easy to tie, uses very little rope, is nearly unbreakable, and is also easy to untie, no matter how much force that has been applied to i
Bowline
is a secure and dynamic alternative to the overhand knot, and is almost as simple.
Figure 8 Knot
. Essentially it is the overhand knot with an extra twist in it. This twist eliminates the sharp turns of the overhand knot which reduce the rope strength so severely, and also more easily facilitates (but not always) the ability to untie the knot after force has been applied to it
Figure 8 Knot
This knot can both be used to create loops in the rope (like the Bowline) or to attach two ropes together (but only if they are the exact same size, material, and degree of wear).
Figure 8 Knot
keep forward of the ship against the dock
Head Line
keep close to pier
Forward Breast Line and Aft Breast Line
prevent from advancing
forward spring
prevent from moving back
aft spring
prevent forwards movement
Stern line
At least _ should be taken.
three ‘figures of eight’ turns
methods to turn the mooring ropes around the bitts for a safe arrangement
For Large size bitts, For Smaller circumference bitts
are arranged as automatic self-tensioning units.
Modern mooring winches
Equipment used for towing should be adequately maintained and inspected before use, as during towing operations excessive loads may be applied to
ropes, wires, fairleads, bitts and connections
Making fast tugs towline
Towing
is fixed by positioning it in the center of four anchors connected to it
buoy
is a simple and rapid means of easing the bitter end of the chain down to the mooring buoy by letting it slide on the wire shackled to the buoy
Trolley Method
has to be slow often less than while at the same time approaching at a smaller angle to the buoy and then gradually hauling in the buoy messenger rope and pulling the vessel slowly towards the buoy using engine kicks at short intervals to control and maintain headway along with mooring winches to haul in the vessel when she nears about 150-200 meters from the buoy
headway approach
are considered favorable to make an approach.
Calm seas with low swell and wind force below 15kts
is provided at the aft to keep the ship at a fixed angle and distance from the buoy
tug
is relatively light cordage used to pull a heavier cable across a gap or through a tube or duct.
messenger line
The term is also used for a line used to pull or lower a package along a downline or jackstay
messenger line
a bight of wire rigged to pass through the ring of a mooring buoy
Slip wire
purpose is to allow the ship’s personnel to control the time of departure and not be dependent on shoreside linesmen
Slip wire
It is always the last mooring out, once the vessel is secured to buoy and designed to be the last mooring released
Slip wire
should be kept away from direct sunlight.
Synthetic ropes
should preferably be stored under the deck for long voyages but if kept on deck they should be covered with tarpaulins or canvass to prevent exposure to sun and seawater or should be kept on gratings
Ropes
While using a _ angles should be avoided
wire rope sharp
When _, care should be taken so as to ensure that the turns on the drum are taken uniformly with sufficient tightness, avoiding any loose or extreme tight turns can cause the rope to get chaffed in between the turns and develop a kink
heaving or slacking a wire
