Comparative Study on Environmental Benefits of Using low-Sulphur Oil and Shore Power Technology for Ship Berthing

Abstract

In order to compare the environmental benefits of two emission reduction measures, i.e. using low-sulphur oil and shore power technology, this paper takes the ships arriving at Guangzhou port as an example, based on the ship data of entry and departure visa of Guangzhou port in 2015, and uses statistical analysis to determine the relationship between different ship types of diesel engines, ship berthing time and ship deadweight tonnage, and based on the use of low-sulphur oil and berthing using shore power air pollutants emission On the basis of emission factors and diesel engine load, the environmental benefits of the two emission reduction measures are calculated by the calculation model established by the dynamic method. The results show that:(1) in 2015, when ships berthing in Guangzhou port used low-sulphur oil with sulphur content of 0.5%, PM10, NOx, SOx and CO2 decreased by 231.6t, 165.5t, 2039.3t and 0t respectively, when using low-sulphur oil with sulphur content of 0.1%, PM10, NOX, SOx and CO2 decreased by 244.1t, 517.1t, 2382.7t and 0t respectively. when ships berthing in Guangzhou port used shore power, PM, NOx, SOx and CO2 decreased by 283.8t, 2975.6t, 2407.7t and -3782.2t respectively. (2) compared with the use of low sulphur oil, the use of shore power by berthing ships has a significant advantage in NOx emission reduction. In terms of particulate matter, SOX and CO2 emission reduction, there is no significant difference between the two measures.

Onshore power supply–trends in research studies

“…The main reason for investing in OPS refers to the environmental benefits that reduce noise, vibrations and emissions of pollution from ships when they are berthed. Hence, in databases there are numerous publications on this subject presenting environmental benefits of using OPS technology (Kizielewicz and Skrzeszewska, 2021;Sciberras et al, 2015;Saxena et al, 2012;Kumar et al, 2018;He et al, 2020;Wang et al, 2021b;Reusser and Pérez, 2021;Chen, 2022;Siu et al, 2022;Su et al, 2023) in particular in the area of CO 2 reduction potential of OPS (Stolz et al, 2021). The research carried out by Reusser and Pérez (2021) (Wang et al, 2021b) is a good example showing "the reduction in the specific fuel consumption of the auxiliary engines, thus reducing emissions in 20% for CO 2 , 34% for NO x and 30% for SO x " thanks to applying CI power configuration.…”

Carbon emission reduction of shore power from power energy structure in China

“…Some scholars taking Guangzhou Port as an example compared the environmental benefits of two emission reduction measures using low-sulfur oil and shore power technology. The results showed that shore power has significant advantages in reducing NO x emissions (He et al, 2020). In addition, quantitative calculations for Kaohsiung Port have shown the long-term potential of shore power to improve environmental and socioeconomic conditions by reducing port emissions (Tseng and Pilcher, 2015).…”

Comparative Analysis of Soft Computing Models for Predicting Viscosity in Diesel Engine Lubricants: An Alternative Approach to Condition Monitoring

“…The potential benefits of engine oil analysis extend to the prevention of costly repairs, reduction of downtime, and optimization of oil change intervals, resulting in early issue cost savings . Furthermore, issues contributing to increased emissions and contaminants leading to excessive exhaust emissions can be revealed through engine oil analysis, thereby offering environmental benefits . Despite the evident advantages of engine oil analysis, background research highlights a lack of definitive answers regarding the frequency at which it should be performed on diesel engines. ,− The frequency of engine oil analysis may necessitate adjustment as diesel engines age, requiring increased effort for reliability maintenance despite improving experience with aging.…”
