YCB Benchmarks – Object and Model Set

In 1988, two-stroke crosshead MODS were the main type of HD on transport ships and accounted for 72.6% of all HD installed during the year: 315 mods with a total capacity of more than 3,200 MW were used on 312 ships.


MBD took the first place in the world in the production of MODS in 1988: 165 engines with a capacity of about 1,690 MW, which accounted for 52.8% of the total production of two-stroke diesels. The company produces 28 brands of mods, covering the power range from 700 to 49300 kW.


MBD manufactures 12-cylinder diesel engines of the K90MS brand with a capacity of 47.3 MW for three container ships. These will be the most powerful engines in the world. The development of the K80MS-S and K90MS-S modifications will allow the construction of the largest container ships: the 12-cylinder K90MS-S is designed for a capacity of 49.3 MW. These engines are characterized by high reliability and low manufacturing and operating costs.


In 1988, Sulzer took the second place in the world in MOD production: 102 RTA diesel engines with a capacity of 1,213 MW were installed on 100 ships, which accounted for 37.88% of the total MOD output. The company produces 10 brands of RTA-type mods for the power range from 1,480 to 41,520 kW. RTA type diesels are characterized by high efficiency (specific fuel consumption of 156-171 g/kWh), which is obtained due to their "long-stroke" capacity, reaching 3.8, as well as the use of a deep exhaust gas heat recovery system and power extraction to the halogen generator. The use of a turbocompound unit increased the efficiency of the EC to 71.7%, and the daily fuel consumption on ships with RTA decreased by 30-40%. Work is underway to increase the efficiency of the diesel engine by increasing the maximum combustion pressure, average piston speed, compression ratio and mechanical efficiency of the diesel engine and turbo charge unit. The company is modifying the RTAs by increasing their capacity by 6.6% (for RTA52, 62, 72 and 84M brands) by increasing the average effective pressure from 1.66 to 1.72 MPa and the piston speed from 7.6 to 7.8 m/s. The engine of the new RTA84C modification, without changing the design, will have a cylinder capacity of 3820 kW at a rotation speed of 100 rpm (previously — 3460 kW at 78 rpm) and is intended for use on high-speed container ships, where an aggregate capacity of 45.8 MW is required. By the autumn of 1988, the volume of all deliveries of RTA diesel engines reached 578 units with a capacity of 5,636 MW; 76 RTA84 and 28 RTA84M diesels were ordered. The most powerful 12RTA84 marine engine is installed on the Harry Truman container ship with a deadweight of 54,500 tons.


Mitsubishi is the third largest manufacturer of two-stroke mods in the world. In 1988, it supplied 48 diesel engines with a total capacity of 298.4 MW, which accounted for 9.32% of the total supply volume of the MOD.
