HW
- High water in port as determined by tides which might
affect the amount of cargo a vessel can load.
Handy Size
- Tankers of about 12,000 to 25,000 DWT.
Harbor Dues
- Various local charges against all seagoing vessels
entering a harbor, to cover maintenance of channel depths,
buoys, and lights. etc. All harbors do not necessarily
have this charge.
Hawse Pipe,
Hawse - The hole in
the bow through which the anchor chain passes.
Hawser
- A cable used in warping or mooring the vessel.
Heating Coils
- Coils located in the bottom of cargo tanks that steam
passes through to heat cargo. The heat lowers the viscosity
of the cargo and permits easier pumping of the cargo
at the discharge port. Vessels in clean service normally
do not have or need heater coils as the viscosity of
the clean products (with the exception of some lube
oils) is high enough to permit easy pumping at atmospheric
temperatures.
Hog (Hogging)
- The condition of a vessel caused by the unequal distribution
of cargo. When a vessel loads too heavily at the ends
it causes an arching, or bending upward, of the hull
at the midships area. This can also be caused by the
vessel working in heavy seas with a large wave under
the amidships section.
Hull
- The body of the vessel not including its masting,
rigging etc.
