LIC. ROSARIO NUÑUBERO

MAIN BODY OF THE VESSEL
IT IS MADE OF STEEL

IT IS WATERTIGHT

THE HULL
HULL DIVISION

IT HAS AN OUTSIDE COVERING.
IT IS CALLED SHELL PLATING
(OUTER PLATING/SKIN)IT ALSO HAS AN INSIDE
FRAMEWORK

IT IS SECURED BY WELDING
STRAKES

THE KEEL
IT IS A HEAVY METAL PLATE
WHICH IS THE MAIN CENTERLINE
STRUCTURAL PART OF THE HULL.
IT IS THE BACKBONE OF THESHIP.

IT RUNS FROM THE STEM AT

THE
FRAMES
THE HULL ALSO HAS FRAMES.
THEY ARE STEEL PLATES THAT
ARE “THERIBS” OF THE HULL
FRAME

TRANSVERSE FRAMES RUN
ATHWART. THEY ARE NUMBERED
FROM THE BOW TO THE STERN
FRAMES GIVE SHAPE AND
STRENGTH TO THE HULL.THEY
ARE FASTENED TO THE KEEL.

BEAMS

THEY JOIN THE STARBOARD
FRAMES TO THE PORT FRAMES
BEAM

THEY HOLD UP THE DIFFERENT
DECKS OF A VESSEL.

BULKHEADS
THEY ARE PARTITIONS THAT
DIVIDE THEVESSELS IN
INDEPENDENT
COMPARTMENTS.THEY COULD BE
CORRUGATED, WAVY OR SMOOTH

THEY INCREASE THE STRENGTH
OF THE VESSEL STRUCTURE.
THERE ARE LONGITUDINAL AND
TRANSVERSE BULKHEADS.
ALL VESSELSMUST HAVE
COLLISION BULKHEADS ON THE
BOW AND THE STERN.

DECKS divide the hull horizontally
while bulkheads divide it vertically.
The ones that divide up cargo spaces
