... ABSTRACT Ship's propulsion efficiency plays a key role in cutting emissions together with other major technological advances in alternative fuel and energy sources, such as batteries and fuel cells. However, the availability and price of energy increases the importance of energy efficiency...

... mass enlargement when using ESS was compared. The gas engine load response was introduced into the energy management strategy as the power ramp limit. According to the case study, the power distribution of ESS can reduce CO2 emissions and fuel consumption by up to 8.3% and 9.8%, respectively, while...

... ABSTRACT In the long-term development of the global shipping industry, air emissions from ships have caused different degrees of impact on the atmospheric environment in various places. Our ongoing research monitoring and management of air emissions from ships based on carbon balance method...

... ABSTRACT Nowadays, many ships begin to adopt hybrid power system to help save fuel and reduce emissions. The key technology of the marine hybrid power system is the energy management strategy, which aims to rationally distribute and coordinate the control of a variety of energy sources under...

.... And then, the vessel waiting time was added into constraint conditions, and carbon emissions were calculated by introducing the forest accumulation conversion factor method. Finally, the improved ant colony algorithm was used to calculate the weight coefficient of each element. The results show that the route...

... ABSTRACT Deepwater drilling platform consumes much chemical and petroleum sources to provide sufficient energy for drilling services, which produces a large amount of carbon dioxide emissions into the atmosphere directly. To reduce the carbon dioxide (CO2) emissions and achieve the carbon...

... with global consensus on low emission of green gases. For example, in April 2018, International Maritime Organization (IMO) announced a plan to cut the shipping sector's overall CO 2 output by 50% by the end of 2050. By using LNG as a fuel, sulphur and particle emission would be reduced to zero and nitrogen...

... ABSTRACT In order to adapt to more international regulations and regional environmental standards, two energy efficiency models introducing the whole life cycle assesment are established. Based on the current energy efficiency system and emission reduction policies of the shipping industry...

... that improves energy efficiency and reduces emission. INTRODUCTION The shipping industry, while making considerable progress in recent decades, is also a major polluter in the transportation industry and a large contributor of greenhouse gases. In order to curb environmental pollution caused by ship...

... ABSTRACT The computational model of ship's exhaust emission is complicated, and the types of data sources required are diverse and the amount of data is huge. The traditional single computer calculation program can't meet the demand of real-time calculation of ship's exhaust emissions. Aiming...

.... The result of study points out that the electric-driven compressor requires less area, reduced local emission of greenhouse gases, less weight, lower cost and higher energy efficiency. As a result, electric motor driven compressor will be applied in Lingshui 17-2 project. While electric- driven system has...

... it with the ISO standard value. INTRODUCTION Since industrialization, the increase in the use of fossil fuels by humans has increased CO 2 emissions. As a result, the global warming phenomenon is accelerating and has a very negative influence on the global ecosystem and human life environment. Since 1992...

... ABSTRACT Owing to increasing fuel price and strict environmental legislation, the use of hybrid electric propulsion systems (HEPSs) has been increasing in recent years. Optimal design has been introduced to play a greater role of HEPS in fuel saving, emission reduction and economic improving...
