.... In this paper, EEDI of 2 target vessels are calculated with the information on the type and size of those ships, along with the engine types and power. In addition, the results of applying technical measures to satisfy the IMO regulations are also discussed. The obtained results suggested the fuel change from...

... reasons. This study first used data analysis to find hidden information in one-year navigation data of a double-ended ferry operated along the Swedish coast. The case study ferry was operated using both bow and stern engines partly loaded. A new feature of the power ratio is defined to describe...

... ABSTRACT Sand engines are first used as sandy headlands and nourishing source in Qinhuangdao, China. To investigate the morphological responses of the submerged and emerged sand engines to a flood process, a numerical model is established for simulations. The results indicate that the flood...

... ABSTRACT The use of shaft generators in marine applications makes it possible to operate the main engine more efficiently and to provide additional power to the electrical system. This paper develops a dynamic model and controller for a hybrid marine propulsion system that operates efficiently...

... engines. With the temperature difference in the ocean, the thermal buoyancy engine changes the buoyancy of the glider and drives the glider to ascend and descend through the water and drive a turbine behind to harvest energy. Based on this harvesting mechanism, firstly, a new-type thermal engine with high...

... ABSTRACT In this paper, an adaptive equivalent fuel consumption minimization strategy (AECMS) is proposed for a hybrid diesel engine/battery/cold ironing power system to eliminate the impact of power fluctuations on fuel consumption and battery life. Equivalent factor (EF) is varied according...

... as fuel instead of LNG, the volume and weight of the fuel tank will triple due to low energy storage density. Therefore, it is common to say that it is difficult to use NGH as fuel for ships that need to place cargo holds, engine rooms and fuel tanks within a limited space. In this study, the concept...

... Abstract An overview of integrating two energy efficient and emission reduction technologies to improve ship energy efficiency under advanced data analytics is presented in this study. The proposed technologies consist of developing engine and propulsion innovations that will be experimented...

... ABSTRACT In this paper, in order to meet the Class requirement for ice class ship, a program based on Newmark algorithm was used to solve the transient vibration of propulsion shaft in time domain caused by propeller and ice impact. It was found that the speed of the main engine decreases...

... to generate a synthetic data-set for training ANN and SVM models for a cylinder model of a main engine. The trained models were tested with a static data-set, an open-loop dynamic simulation, and a closed-loop dynamic simulation, and compared to the original models. The results show that the outputs from...

... (main engine, auxiliary engines, propeller, HVAC, exhaust system, etc.) as well as the non-typical ones in the latter case (sand moving through the pipelines, winches, dredging pumps, etc.) are taken into account. The prediction is based on vessels drawings and noise source properties, both provided...
