Esempio 4 LPG
This vessel is a large and high-speed LPG carrier
that is acceptable at most Japanese LPG
terminals at full draft condition with about
45,000mt cargo, also equipped with special
instruments that enable her to call at
high-pressured LPG terminals prevailing in
mainland China where import volume of LPG is
rapidly expanding in recent years. With this new
deployment, K LINEs LPG fleet consists of 3
VLGC (Very Large Gas Carrier), which will provide
our customers with a competitive and reliable LPG
transport service with maximum safety.

Esempio 5 LNG
LNG tankers are double-hulled ships specially
designed and insulated to prevent leakage or
rupture in an accident. The LNG is stored in a
special containment system within the inner hull
where it is kept at atmospheric pressure and
-256F. Three types of cargo containment systems
have evolved as modern standards. These
are      The spherical (Moss) design      The
membrane design      The structural prismatic
design Most LNG ships use spherical (Moss)
tanks, and they are easily identifiable as LNG
ships because the top half of the tanks are
visible above the deck. The typical LNG carrier
can transport about 125,000 - 138,000 cubic
meters of LNG, 17 which will provide about 2.6 -
2.8 billion standard cubic feet of natural gas.
The typical carrier measures some 900 feet in
length, about 140 feet in width and 36 feet in
water draft, and costs about 160 million. This
ship size is similar to that of an aircraft
carrier but significantly smaller than that of a
Very Large Crude oil Carrier (VLCC). LNG tankers
are generally less CMS polluting than other
shipping vessels because they burn natural gas in
addition to fuel oil as a fuel source for
propulsion.

Esempio 7Refrigerated cargo
Ship designed with a multi deck hull which
includes an arrangement of refrigerated holds and
tween  decks specifically for the carriage of
perishable cargoes. The cargo handing mode is
lift on/lift off to and from the holds (and
tween decks) by way of weather deck (and tween
deck) hatches
