The reporter learned from Port Ship Co., Ltd. yesterday that the 17,500 ton chemical shipbuilding ship built by the port ship for the Norwegian shipowner Rederiet Stenersen AS was successfully completed and will be delivered on August 22.
The 17500-ton chemical tanker was designed by Port Ship Company and a well-known European design company with a total length of 156.50 meters, a width of 23.80 meters, a model depth of 13.80 meters, a structural draught of 9.50 meters, a design speed of 15 knots, and a classification of DNVGL. The ship is integrated. A number of international and domestic technologies are leading the world in environmental protection, energy saving, and operational reliability, marking the city's shipbuilding level has leapt to a new level.
The ship's unique slender half-V hull line type + upright type column reduces the ship's navigational resistance while allowing the ship to draw deeper under no-load or under-load conditions, and the propulsion efficiency is higher, effectively reducing the number of ships. Comprehensive fuel consumption under loading conditions; direct-drive permanent magnet low-speed shaft generator, equipped with active front-end low-frequency inverter, improving power factor and generator efficiency, reducing power consumption of power system; world's first application of high-power lithium ion The battery energy storage system can effectively collect, store surplus power, discharge to the grid when needed, reduce the peak of power consumption, reduce the frequent start of the standby generator, and fully automatic 'take me home' system with one button operation, avoiding the conventional ship host After the failure, the suspension, flight delay and safety risks; the flexible coupling uninterrupted shore power operating system is the first in China, which can realize the seamless docking with the shore power when the ship is docked, effectively avoiding the power outage of the conventional ship when switching the shore power. The impact of structural optimization based on accurate finite element calculations reduces the amount of steel used in the cargo tank area and reduces the ship's own weight, compared to other chemical tankers of similar tonnage. Tank capacity increased by 15%, to achieve maximize cargo capacity.
The ship incorporates a green design concept. The main and auxiliary system are equipped with an exhaust gas aftertreatment device and a selective catalytic reduction reaction device, which can reduce the chemical reaction of carbohydrates in the exhaust gas into nitrogen and water, effectively remove harmful substances in the exhaust gas, and reduce Air pollution; the water tube lubrication of the manifold is used to prevent the pollution risk caused by the leakage of the oil in the conventional ship; the high-power electrical equipment on the ship is widely used in variable frequency energy-saving technology, the cabin ventilation system, the central seawater cooling system can be changed according to the environment, the system The demand realizes the frequency conversion control; the air conditioning return air in the living area uses the rotary heat exchange mechanism to adjust the temperature of the fresh air inlet, greatly reducing the power consumption and running time of the air conditioning compressor unit. The cabin noise of the crew is only 45 decibels, far below the international standard requirement of 55 decibels. So that the crew really has a quiet and comfortable 'home'.
