Plimsoll lines let us understand how to read these load lines that you find mark
on the side of a ship
the purpose of a load line or a plimsoll line is to ensure that the ship is not
overloaded and has sufficient freeboard
it indicates the maximum safe draft
you
and the minimum freeboard for the ship in various operating conditions
the location of the plimsoll line is determined by a classification society
after survey in the ship
you
plimsoll line mark allows one to know the safe draft
draft is the vertical distance between the waterline and the bottom of the hell
or keel
the heavier the load the more as the draft Lin
you
plimsoll line allows one to know the freeboard
a free board is the vertical distance between the water line and the shear of
the ship where water can enter the vessel
you
plimsoll line allows one to know the volume of load that is safe to carry
overloading can cause the ship to sink
you
there are many load line marks for different dents
of water or different sea climates
it is important to know that higher the density of water stronger is the upward
buoyant force
you
the order of less tent water to hide ants water is as shown
you
this means one can load more cargo for dense water
you
once having understood that oceans are of different density each having a safe
load line it is time to understand how to read the lines the circular symbol
with a line passing directly is the plimsoll line
the line represents the imaginary water level
the plimsoll line is directly below the deck line the deck line is the freeboard
line issued by the classification Society
the summer load line is the primary mark
it is from this line that all other lines were marked derived
the winter load line is 148 of the summer load Draft
placed below the summer line the tropical load
is 148 of the summer low draft
placed above the summer line the other load lines are
fresh water
tropical freshwater
winter North
