Characteristics of Economic and Environmental Benefits of Shore Power Use by Container-Ship Size

Abstract

To combat climate change, efforts to reduce greenhouse gas (GHG) emissions are being made in all industries. The shipping sector is also one of the industries that emits GHG, including carbon. One way to reduce GHG emissions in the shipping sector is to use shore power (SP) rather than auxiliary engines during berthing. Port authorities are actively expanding SP facilities because it is possible to achieve the long-term goals of environmental benefits and green ports. However, the low economic feasibility of SP is a stumbling block for ship operators. Therefore, in this study, an economic analysis of SP use was conducted by container-ship size from the perspective of ship operators in consideration of benefits from differences in fuel oil and electricity prices, benefits through carbon emission reduction, and incentives from the port authorities. The result of the analysis showed that the benefit from the price of oil as well as the converted benefit from carbon emission reduction increased according to the size of the vessels. The economic analysis of a single port confirmed that small ships providing feeder services presented economic feasibility due to low installation costs and increased number of calls, while insufficient economic feasibility was presented for large ships above the old Panamax class due to the increased costs for installation. However, economic feasibility differs widely depending on whether port incentives are provided, and it was estimated that even large ships will be able to secure the economic feasibility of using SP if additional calls are made to ports that provide similar policy advantages.

Analysis of Economic and Environmental Benefits of Green Business Practices in the Hospitality and Tourism Sector

“…Compliance with environmental regulations is facilitated, reducing the risk of fines and legal issues (Zhu et al, 2022). Additionally, green practices boost employee engagement, productivity, and morale (K. Kim, 2022). By reducing resource consumption, minimizing waste, and mitigating environmental impacts, green practices contribute to the long-term sustainability of the sector (Guo & Yang, 2019).…”

Scientific Reports Shore Power Load Forecasting based on a Novel Transformer Method with Feature Selection

“…Shore power can re-duce the emission of polluting gases in the port area, so it has become widely used in the big ports of the world [4]. However, the massive transformation of shore power berths will bring new challenges to the power supply system [5]. Load forecasting technology can predict the possible future load according to the feature information and forecasting model before the ship docks.…”

Application of Generator Capacity Design Technique Considering the Operational Characteristics of Container Ships

“…As the container transportation industry has developed over the past 20 years, the size of container ships and the number of containers that they accommodate have increased [1][2][3][4][5]. Accordingly, the construction of bigger ships, which is a confirmed method of reducing container shipping costs, is gradually accelerating [6][7][8]. By building bigger containers ships, advantages such as economies of scale for marine logistics and transportation, reduction of construction costs, and securing competitiveness in the fierce cargo market can be obtained [9][10][11][12].…”
