1 Introduction

As an important part of the national economy and an indispensable part of production and life, transportation industry plays an important role. As an important cornerstone of the transportation industry, shipping is a transportation mode with large transportation volume, low energy consumption, low cost and environmental protection. It plays a very important role in the transportation of trade goods in China and the world. In recent years, with the rapid development of big data, artificial intelligence, machine learning and other technologies, new concepts such as smart city, smart water conservancy, smart maritime, smart robot and smart home have emerged one after another. The concept of “intelligent transportation” originated from land transportation and was later cited to water transportation, resulting in the concept of “intelligent shipping”.

Intelligent shipping is a comprehensive application of cloud computing, big data, Internet of things, sensors and other technologies guided by the construction of big data center. It is a modern shipping service system that promotes cross departmental cooperation, cross regional information resource integration, improves transportation efficiency and reduces transportation costs. The basic components of intelligent shipping include five elements: intelligent ship, intelligent shipping insurance, intelligent port, intelligent supervision and intelligent service. The sustainable development of intelligent shipping requires the organic coordination and common development of all elements.

There are many key technologies used in intelligent shipping, such as cloud computing, big data, Internet of things, sensors and so on. Cloud computing is a new type of IT infrastructure with high performance, high speed and diversification. In the development of intelligent shipping, it will organically combine computing technology with traditional shipping, which is a collision combination of traditional technology and new technology in the development. “Cloud” refers to a virtual network. Cloud computing is a network that provides resources. Resources like cloud can be accepted and used in real time. In the early stage of the development of cloud computing, it is only simple distributed computing, and then the combination of computing results. Now it has developed to decompose the huge data in the cloud into infinite small tasks through computer processing, and then process and analyze these results through the server system and return them to users. Cloud computing technology is the core of making traditional shipping intelligent. Through multi data analysis, it can improve the synergy between ships and logistics and have efficient operation. With the “Internet plus” action and the national big data strategy advancing, data management, data management and data innovation will gradually influence the development of national governance.

In recent years, intelligent shipping has developed rapidly in China and around the world. In China, the proposal of the CPC Central Committee on formulating the 13th five year plan for national economic and social development issued in 2015 mentioned the need to speed up the improvement of water transport infrastructure network and the implementation of high-tech ship intelligent manufacturing; The guiding opinions on the development of intelligent shipping jointly issued by the Ministry of transport and other seven departments in 2019 put forward the strategic objectives and ten tasks for the development of intelligent shipping, carried out the top-level design of intelligent shipping development, and improved China’s shipping competitiveness; In addition, the medium and long term development planning outline of scientific and technological innovation in the field of transportation (2021–2035) issued by the Ministry of transport in 2022 mentioned the need to strengthen the promotion of intelligent shipping technology innovation, so as to promote the application of global shipping service network based on blockchain. Internationally, the 98th meeting of the Maritime Safety Committee of the International Maritime Organization (IMO) (msc98) held in 2017 included “autonomous unmanned ships” as a new topic, and intelligent shipping has gradually become a research hotspot.

With the increase of the number of ships worldwide and the development of large ships, the shipping industry is facing many challenges, such as serious environmental pollution, increased labor cost, insufficient safety and so on. The development of intelligent shipping will effectively meet these challenges. Intelligent shipping can effectively improve shipping capacity, promote the development of green technology, reduce greenhouse gas and pollutant emissions, save energy and improve shipping safety. However, the development of intelligent shipping is still in its infancy, and the literature on the overall framework of intelligent shipping is relatively lacking. This paper mainly summarized the framework system of intelligent shipping from five aspects: intelligent ship, intelligent port, intelligent navigation insurance, intelligent supervision and intelligent service, summarized several key technologies of intelligent shipping, then gave examples of successful cases of intelligent shipping application in China and abroad, and finally put forward the current shortcomings and challenges of intelligent shipping. The future development and research direction of intelligent shipping will be prospected.

2 Intelligent Shipping System Framework

Intelligent shipping is mainly divided into five aspects: intelligent ship, intelligent port, intelligent aviation insurance, intelligent supervision and intelligent service. The overall framework of intelligent shipping is shown in Fig. 1. The following will mainly summarize the definitions and research status of these five aspects, and specifically introduce the two aspects of intelligent ship and intelligent port.

Framework of intelligent shipping

2.1 Intelligent Ship

Intelligent ship refers to a ship that automatically senses and obtains the information and data of the ship itself, marine environment, logistics, port and other aspects by using technical means such as sensor, communication, Internet of things and Internet, and realizes intelligent operation in ship navigation, management, maintenance and cargo transportation based on computer technology, automatic control technology and big data processing and analysis technology, so as to make the ship safer, more environmentally friendly More economical and reliable (Li et al. 2021). Compared with traditional ships, intelligent ships have significant advantages in economy, safety, reliability, environmental protection and efficiency (Wang et al. 2021). At the same time, although ship intelligence reduces the impact of human factors on navigation safety, the research on its safety is still the focus of research in the shipbuilding industry (Zhang et al. 2021).

Internationally, Japan began to study AI ships with intelligent navigation function in the 1980s; South Korea launched the world’s first intelligent ship in 2011. At present, its intelligent ship 2.0 plan is being promoted; Rolls Royce completed the world’s first merchant ship remote operation in 2017, developed the world’s first fully automatic ferry in 2018, and conducted automatic navigation test at the same time;, In 2019, Japan announced that it had completed the world’s first sea test of intelligent ships and completed various test projects of the interim guide for autonomous ship test of the international maritime organization. At home, the action plan for the development of intelligent ships (2019–2021), prepared and issued by the Ministry of industry and information technology, the Ministry of transport and the Bureau of science, technology and industry for national defense in 2018, aims to promote the high-quality development of China’s shipbuilding industry and keep the development of intelligent ships in China in step with the advanced level of the world. Some intelligent ships that have been developed are shown in Fig. 2.

2.3 Intelligent Aviation Insurance

The core elements of intelligent navigation support system include shore based system, ship shore communication, navigation and positioning, information service and data standard. Ship shore communication is a channel that provides all information exchange and sharing. Intelligent ship navigation requires a large number of data exchange between ship and shore and between ships, which requires faster data communication bandwidth and more efficient and convenient data communication technology. Navigation and positioning provides basic location information, dynamic change information and unified reference time scale for all other technical elements and system cores. The data model includes data exchange standard protocol and data structure model. It integrates all marine related information, transmits according to the unified business model and data, and establishes a complete information service system to meet the needs of users (Gao and Wang 2019).

2.4 Intelligent Supervision

With the intelligent development of ships and ports, shipping supervision must change and progress, realize intelligent supervision in ship inspection, safety supervision, health and epidemic prevention, border inspection and commodity inspection, promote the integration and sharing of information, realize a single window, comprehensively create a new pattern of shipping supervision with information and intelligent means, develop and utilize supervision resources and improve quality and efficiency.

2.5 Intelligent Services

Intelligent service is to realize intelligent shipping scheduling and shipping service through an open, standard and unified shipping comprehensive information service system based on multi-dimensional information resources. By exchanging and sharing data resources, various intelligent information services such as channels, ports, ships, logistics, pilotage, rescue, shipping management, shipping market and public services can be realized; Realize the release, exchange and sharing of information among shipping participants; Integrate various shipping business application systems, process and exchange relevant data and information, and provide government services, business services and public information services for all shipping participants.

3 Typical Cases of Intelligent Shipping

3.1 COSCO Intelligent Ship

Intelligent ship is an important part of intelligent shipping. The core of intelligent ship is ship energy efficiency system. Energy efficiency system is a cooperative system between ship and shore, and a control system for ship operation information and performance indicators. Ocean Shipping Group will cooperate with group A in the 20th century. According to the group’s intelligent technology, the installation of its ships can monitor and detect the marine environment and ship performance. After mastering the data, it can monitor the operation of the ship and even the whole team. After half a year of trial operation, it will evaluate the economy before and after operation. The following table shows the economic improvement results between intelligent ships and traditional ships (Table 1).

Table 1. Benefit evaluation of single ship intelligent ship (Duan 2017)

In terms of operation results, the installation of energy efficiency system can upgrade traditional ships to intelligent ships, which can save about US $7.855 million per ship every year, save human resources, save expenses and improve management level in daily operation. This result improves the feasibility of changing from single ship intelligence to fleet intelligence in the future, which not only saves expenses, but also saves resources, protects the environment and liberates the labor force.

3.2 Xiamen Ocean Automation Terminal

When artificial intelligence and 5g emerging technologies are organically combined with Xiamen ocean terminal, the automatic shipping terminal brings not only management transformation and efficiency improvement, but also a mileage of national marine terminal automation. In the upgrading process of traditional wharf, mechanical automation came first, and now it is a comprehensive intelligent simulation platform. Compared with traditional container terminals, fully automated container terminals can reduce operation and operation costs, save energy by more than 25% and reduce carbon emission by more than 16%.

Thanks to the help of intelligence, Xiamen ocean automation terminal saves more than 25% of energy, improves efficiency by 20% and reduces front-line operators by 70% compared with traditional terminals. The container throughput has increased from 300000 containers at the beginning of production in 2011 to more than 2 million containers in 2018. After seven years of production, the terminal throughput has increased nearly seven times. In 2019, Xiamen ocean automation terminal will continue to maintain double-digit growth. Since Xiamen ocean terminal fully automated wharf was put into commercial operation in March 2016, it has achieved “zero” safety accidents, and the container volume, work efficiency and economic benefits have been accelerated.
