..., the required caisson width will be reduced, and the cost and period for constructing breakwaters may be reduced(Figure 1). In Japan, an asphalt mat(hereafter called "AS mat") as a friction-enhancing mat was introduced for a caisson-type breakwater in the Wakayama Port in 1963(Kagawa.,1964). Since...

... ABSTRACT We proposed external modules for autopilot of underwater robots to promote the use of robots in port inspection. This research focuses on commercially available small underwater robots. We examined the requirements for the external module and the procedure of the target task...

... of IG waves. An empirical formula to estimate IG wave heights is developed, based on the local swell waves properties. INTRODUCTION Infragravity (hereafter IG) waves play an important role in nearshore dynamic processes and ship motions in the port. The generation of IG waves is closely related...

... many ships, containers, vehicles, and other debris ashore. Hiroi et al. (2012) reported that tsunami debris and oil spilled from damaged oil complexes caused fires on the sea surface, and the fire expanded to the affected area in Kesennuma Bay, Miyagi Prefecture. In most other ports, tsunami debris...

.... INTRODUCTION Ningbo–Zhoushan Port is an important maritime gateway to the Yangtze River Delta in China, which plays an important role in ensuring the transportation of energy and raw materials in the Yangtze River Delta and promoting the industrialization. In 2017, China formally issued the "China (Zhejiang...

... Abstract This paper presents a novel initiative for reliable high–resolution forecasts on prevailing sea states at 50 important ports worldwide (Accu-Waves; http://accuwaves.eu/) . Its goal is to support safe navigation, unhampered vessel approaching to busy harbored areas, and secure ship...

... Abstract Establishing a system of tide gauge stations around ports for real-time tide observations is an important research topic and predictions are needed for estimation of water depths for vessels and cargo vessels at piers. The purpose of this research is integrating water depth...

... of seal integrity was demonstrated. Efforts made in improving the design and testing of the suction plug-port assembly, and overcoming the challenges during subsea handling are shared in this paper. The purpose of this paper is to raise awareness of several important consideration for better design...

... conditions, it has a broad promotion prospects. INTRODUCTION Hadarom port, as an extension of Ashdod port and Hayovel port in Israel, is designed for Maersk Triple E-class container vessel of more than 18,000 TEU, with an overall length of 400 meters. In general, the work scope of Hadarom port comprises...

... advanced navigation technology and backward port transportation management has become a prominent contradiction in the development of waterway transportation in China at present. In order to solve this contradiction, it is necessary to strengthen the management of port ships entering and leaving Port...

... ABSTRACT Because of rising concerns on traditional fuels in ocean shipping, more ship owners and operators are considering the switch of fuel to clean energy liquefied natural gas (LNG). Many US ports are constructing facilities related with LNG bunkering to meet the demand increase for LNG...

... ABSTRACT World trade increasingly relies on longer, larger and more complex port systems integrated to the older ports, where maritime transportation is a vital backbone of such operations. Port systems are more prone to being risk oriented. Many specific methods have been found to assess risk...

ABSTRACT With the rapid development of China's economy, especially the implementation of the "Ocean Power" strategy, the number of ships has increased rapidly, and the trend of high-speed and large-sized ships is increasingly evident. The risk assessment of port waters is of great significance...
