Unformatted text preview: the parts of ship so that they will be
fair, that is, without kinks, bumps, or waves. Draft
marks on the stern end of a river barge.
Drift Pin ----A small tapered tool used in
aligning holes in adjacent members.
Drop Strake ----A strake discontinued near the
bow or stern.
Drydock ----A watertight vessel fitted with
pumps and valves usually built in a u-shape. The
valves are opened, the vessel sinks, the vessel to
be docked is pulled over the drydock deck, the
valves are closed and the pumps are started, as
the drydock becomes more buoyant, drydocking
the vessel to be repaired. Fairlead ----A fitting through or over which a
rope, line, etc., may be led so as to change its
direction without excessive friction.
Fairwater ----Plate or casting used to preserve
streamline flow past hull structure or propeller
Fathom ----Six feet.
Fathometer ----A device to measure the depth
of water, by timing the travel of a sound wave
from the ship to the ocean bottom and return.
Faying Surface ----The contact surface between
two adjoining parts.
Fender ----A portable device to protect a ship
when bumping a pier; sometimes made of wood,
rope, etc.; permanently installed extension which
protects the hull of a ship in docking.
Fidley ----Casing top over boiler room. E6002 – Ship Terms & Definitions p. 10 © C.G.Daley Fidley Hatch ----A hatch over boiler room.
Figurehead -- The bust, often of a woman, on
the bow of a vessel, just under the bowsprit.
Flagstaff ----Flagpole at stern of ship; ensign
Flange ----A part of a plate or shape at, or nearly
at, right angles to main port; to bend over to
form an angle. Foundations, Auxiliary ----Supports for small
machinery, such as winches, condensers,
Frames ----Ribs forming the skeleton of a ship.
Frames ----Continuous Frames combining side
frames and floors. Flotsam ----Floating objects or debris in the
water - wreckage that floats after a vessel sinks. Frame Line ----The intersection of the moulded
surface with a vertical plane perpendicular to the
centerline (transverse plane). Frame lines are
shown in the body plan of the lines drawing.
They get their name from the fact that shell
"frames" or ribs usually are made to this shape
and installed transversely in the ship. The lines
drawing consists of three views; a half-breadth
plan, a profile view, and a body plan (See Fig.
7). These views each show only one side of the
ship (usually, the port side), because all
dimensions for the starboard are equal and to the
opposite 'hand'; that is, the ship is symmetrical
about the center line. Fore and Aft ----In line with the length of the
ship, longitudinally. Frame, Side ----Frame inside a ship, above and
connecting to margin plate or floor plates. Fore and Aft Gangway ----A walkway between
deckhouses at or near centerline of ship. Frame Spacing ----The fore and aft distance
between adjacent frames. Forebody ----A hull form forward of the
midship section. Frame, Web ----A heavy side or continuous
frame, made with web plate for extra stiffness. Forecastle ----The forward upper portion of the
hull, sometimes used for the crew's quarters. Freeboard ----The vertical distance from the
upper watertight deck to waterline, when the
ship is fully loaded. Flare ----The sudden widening of the shell at
top near the bow.
Flat ----A small partial deck (built level) without
Floor ----The lower portion of a transverse
frame, usually a vertical plate extending from
center line to bilge, and from inner to outer
bottom. Forefoot ----The part of the keel which curves
and rises to meet the Stem. Freeboard Mark ----(See Plimsoll mark.) Forepeak ----The large compartment or tank, at
the bow in the lower part of the ship. Freeing Port ----Hole through bulwark which
provides ready drainage of water from deck. Forepeak Bulkhead ----Collision bulkhead;
bulkhead nearest bow. Funnel ----A smokestack of a vessel. Forging ----Steel worked to special shape by
hammering while red hot. Furnace ----A heater or large forge for heating
plates or shapes for bending; to bend by heating
in furnace. Forward----Near, at, or toward, the bow of the
Forward Perpendicular (F.P.)----A vertical
line through the intersection of the stem with the
load water line.
Foundations ----Supports for boilers, engines,
and auxiliary machinery. G
Galley ----A cook room or kitchen.
Galley Dresser ----A cook's work table. E6002 – Ship Terms & Definitions p. 11 © C.G.Daley Galvanizing ----Coating metal parts with zinc
for protection from rust.
Gangway ----A passageway, a ladder, or other
means of boarding a ship.
Garboard Strake ----The course of plates next
to the keel of a ship.
Gasket ----Packing of canvas composition, or
other material, used in making a tight joint.
Girder ----Fore and aft stiffening member for
deck or bottom shell.
Girth ----Any expanded length.
Grab Rods ----Bent rods welded to bulkheads
or ship's side to form a ladder.
Grating ----Light platform or walkway built up
of metal bars, used for access to machinery.
