Ensuring the Environmental Friendliness of Drillships during Their Operation in Special Ecological Regions of Northern Europe

Abstract

The features of the operation of the drillship-type vessels in special ecological regions of Northern Europe are considered. The main gap in the study of these systems is to determine the optimal degree of recirculation. The requirements of the International Maritime Organization for the emission of nitrogen oxides from the exhaust gases of marine diesel engines are given. The aim of the study is to determine the optimal degree of recirculation of exhaust gases of a 16V32 STX-MAN marine diesel. During the research, the optimal degree of exhaust gas recirculation varied in the range of 0–21%, the load on the diesel—in the range of 35–95% of the rated power. It was established that in this case, the emission of nitrogen oxides decreases up to 7.7–33.6%, the specific fuel consumption increases up to 0.2–3.5%. It was also found that the use of gas recirculation in the range of 18–21% at loads of 35–55% leads to a critical increase in exhaust gas temperature. It is advisable to use exhaust gas recirculation in the range of 6–15% to ensure the environmental friendliness of the operation of the drillships. In these modes, the maximum reduction in nitrogen oxide emissions is ensured with a minimum increase in specific fuel consumption. Future studies should be directed at the development of the criteria for the environmental stability of sea vessels.

Solar Energy: Revolutionizing Shipping Industry Towards Sustainability and Environmental Stewardship

“…Technical challenges, such as efficient panel placement and performance under adverse weather conditions, have been identified. The economic viability of solar integration on larger cargo ships remains a subject of debate [7,8].…”

“…The use of solar power in the marine industry has seen significant growth in recent years, and many ship-owners and operators recognize the benefits of using renewable energy to power their vessels [7]. Solar panels can be installed on the deck of ships to capture energy from the sun and transform it into electricity that can be used to power the shipʹs electrical systems, lighting, and even propulsion systems.…”

Development of method for managing risk factors for emergency situations when using low-sulfur content fuel in marine diesel engines

“…The operation of marine internal combustion engines of sea and inland water transport vessels is carried out not only with maintaining the required power and meeting the requirements of manufacturers, but also with maintaining the environmental performance of their operation. The main environmental indicators of the operation of marine diesel engines are the concentration of sulfur oxides SOX and nitrogen oxides NO X in the exhaust gases [7,8]. Their values are determined in accordance with the requirements of Annex VI of the International MARPOL Convention.…”
