Shanghai Shipyard and DNV, Wärtsilä jointly launched the concept design of bulk carrier

During the 2012 Greek Poseidon Maritime Exhibition, the Shanghai Ship Research and Design Institute and the Norwegian Classification Society (DNV) and Wärtsilä jointly launched the concept design of the “Green Dolphin” Handy Bulk Carrier (see photo). The ship has a total length of 180 meters, a width of 32 meters, a design draught of 9.5 meters and a deadweight of 38,800 tons. It makes full use of the existing mature technology, has the characteristics of low energy consumption, safety and reliability, flexible operation and easy maintenance, and can meet the requirements of a series of new maritime regulations such as energy saving, emission reduction and environmental protection.
Hu Jintao, dean of the Shanghai Shipyard, said that the most eye-catching part of the ship is the low fuel consumption and a series of new marine regulations on environmental protection. In terms of fuel use, the vessel offers ship owners a variety of freedom options, with an emissions treatment system for heavy oil applications, as well as flexible switching to low-sulfur or LNG fuel modes. Hu Jintao also stressed that in order to meet the profit requirements of shipping companies to the greatest extent, in the design process, the designers extensively solicited the opinions of ship owners and shipbuilding companies to ensure that the ship can meet more individual needs while meeting the global demand. The mooring requirements for dockable flexible bulk carrier ports.
It is also known that the hull design of this type of ship is jointly completed by Shanghai Shipyard and DNV. Compared with the traditional ship type, it greatly improves the overall performance under different load, speed and sea conditions, and improves through a combination of various design methods. Promote efficiency. The vessel is equipped with a Wärtsilä 5RT-flex50-D two-stroke low-speed diesel engine that complies with the International Maritime Organization's Tier II standard and is equipped with a fuel mode switching system that provides shipowners with a variety of fuel options. At the same time, the vessel can be equipped with a selective catalytic reduction tail gas scrubbing system, shaft torque and fuel consumption monitoring equipment to facilitate and accurately monitor fuel consumption.
The ship's Energy Efficiency Design Index (EEDI) is reduced by 25% from the baseline. EEDI is an indicator for measuring the energy efficiency of ship design and construction. The calculated EEDI value is based on the CO2 emissions calculated from the propulsion power required for the ship to sail at a certain speed and the associated auxiliary power consumption. The lower the energy consumption of the ship.
In addition, the vessel is housed in a large open-cabin cargo bay with electric deck machinery to increase loading, unloading and cleaning efficiency, reducing port turnaround time; equipped with ballast water treatment systems for ballast water and cargo tanks Fully equipped with compressed air, electricity and washing equipment.
