The world's first 6RT-flex48T-D ship was born in QMD

November 25, 2011, the world's first Wartsila QMD-Wartsila 6RT-flex48T-D in Qingdao Qiyao Wartsila MHI Linshan Marine Diesel Works successfully completed the acceptance test bench, this six-cylinder host maximum output power It is 8730 kW (11,880 hp), adopts an economical combustion mode, with an average effective pressure of 19 bar, a maximum burst pressure of 170 bar, and a total weight of 214 tons, which is classified as a GL classification society. The aircraft will be installed on a 1,100-car container ship built by Port Marine Co., Ltd. for the British company PAPER. Shipowner representatives, representatives of Jiangsu Port Shipyard, GL Ship Inspection and QMD employees witnessed this historic moment.

The RT-flex48T-D is an optimized model based on the original RTA48 mainframe. Compared with the traditional RTA48 mainframe, the new RT-flex48T-D is more fuel efficient, more environmentally friendly, lower cost and more efficient. In terms of emissions, the new design meets the IMO International Maritime Organization's Tier II emission standards and lays the foundation for a higher level of Tier III standards. In terms of fuel consumption, due to the precise injection timing function of the EFI machine, the main engine can adopt different combustion modes under different working conditions, so the main engine fuel consumption is greatly reduced. In terms of oil consumption, the machine adopts CLU-4 pulse cylinder lubrication, and the cylinder oil timing injection replaces the previous flooding lubrication method, which significantly reduces the oil consumption. In the context of the sluggish shipping industry and high oil prices, low fuel consumption hosts are popular with shipowners. The RT-flex48T-D mainframe is becoming the mainstream model in the shipbuilding market today, and the market prospect is very broad.

In the face of the world's first machine, many of the key components are the world's first, there is no precedent, but also face the difficulties of time-critical tasks. Each department keeps in mind the mission and vision of QMD. In the face of difficulties, there is no retreat. Various departments are involved in the project. The project is responsible for drawings, design, procurement, welding, inspection, assembly, and commissioning until the project is successfully completed. . In the face of problems, breaking the boundaries between departments, everyone brainstormed and fully mobilized the subjective initiative of each employee, so that the problem can be resolved on time and quality. During the project, shipowners, shipyards and patentees all made a high evaluation of QMD's work.

The smooth delivery of the world's first Wartsila 6RT-flex48T-D at QMD marks QMD's move towards the world's best two-stroke engine producer.
