 The
largest vessel that is carrying LNG (Liquid Natural Gas) definitely
is one of the most beautiful technical outfit built ever. It is
part from the fleet of BP Shipping, but it was built is South Korea
in the ship-yard of Hyundai Heavy Industries. This ship is the first
from the series of diesel-electric gas vessels with dual-fuel (DFDE).
It was planned for the ship-owner and will give a new movement into
LNG carriers.
The
vessel is combining a economic and operational factors in some great
correlation, which is making this vessel very important and very
good for the ship-owner and even for the whole shipping industry.
The power system is consisted by main engine,
which is giving almost the whole power for the moving of this vessel.
The innovations for the power systems are making this vessel unique.
The power is well controlled by electric propulsion system, the
system Ecobot and some other control systems. All this is building
one engine that is giving enough electricity for the whole ship
and for the tanks. The heart of the new DFDE is the Ecobot system,
which is using LNG gas that evaporates from the tanks during the
transportation, to fuel the main power engine. The main engine work
pretty good with gas and heavy fuel oil, only depends from the situation.
The new DFDE system is nearly 2-4% more expensive than the other
older one, but it is with more than 10% more effective.
The
vessel British Emerald is the largest ever built LNG Carrier. The
ship can carry 155,000 cubic meters natural gas. Its measurements
are 288m length and 44.2 m breadth. The depth of British Emerald
is 26 m. The speed that the vessel use for crossing is 20 knots,
and the maximum speed is about 23 knots.
