The
cargo ship Arctic Discoverer is one of the most impressive LNG Carriers
built last years. The ship has deadweight of 75,485 metric tons
and gross tonnage of 118,571 gross tons. The cargo capacity of the
gas carrier is 140,000 cubic meters. All these measurements are
really impressive, but the thing, which amused us was the Ice class
of the LNG Carrier. Such ships are really dangerous and even easier
pressure over the hull may cause explosion, but Arctic Discoverer
is designed to sail in the ice. The ship was built by Mitsui Engineering
& Shipbuilding Co Ltd. This is one of the high quality ship-yards
in Asia creating really amazing ship in design and engineer point
of view. The ship has overall length of 289.50 meters and length
between perpendiculars of 277.00 meters. The beam of the ice class
ship is 48.40 meters, draught of 26.50 meters and draft of 11.30
meters, when the ship is fully loaded. The
important feature of the ship is the ice strengthening of the hull,
which allows for the vessel to carry cargo in North Sea and other
arctic seas. The ship Arctic Discoverer is really good designed
with low CO2 emissions, high power and improved shape for high speed.
The accommodation is created according to latest requirements for
human resources and life at sea. The hull is double sided all around
the ship. The
ship is driven by Steam turbine with total power of 27,000 kW at
81 rpm. The maximum speed of the vessel is 21.00 knots. The cargo
handling is managed by specially automated system, which increases
the speed rate for loading and discharging of cargo, with low power
from the auxiliary diesel generators. The ballast operations are
also automated operated by computerized system, which increases
the rates for loading ballast. The system is called NAUT-AW integrated
in DNV system. The LNG cargo is quite dangerous and the restrictions
to such type of ships are very big. Really Arctic Discoverer is
ship with very interesting design and very interesting engineering. date: 18th August, 2009
