In our college there are the Department of Marine Navigation,Department of Marine Engineering, Department of Shipping Management and Department of Foreign Languages, offering speciahies of Marine Navigation, Marine Engine Control, Marine Electrical Equipment Control, Marine Radio Communication, International Shipping Management and International Finance and Accounting. We have 3 types of education: the education of formal college schooling, the training for implementation of the 95 revised STCW Convention and the continuation education. Meanwhile we undertake different training of COSCO’s contracted seafarers overseas and other managerial per-

超声空化在船舶与海洋工程中的应用

Biofouling on ships and offshore structures has always been a difficult problem to solve,which not only jeopardizes the structural strength but also brings great economic losses.Ultrasonic cavitation is expected to solve this problem due to its characteristics of no damage to structures and no pollution.Starting from the phenomenon and mechanism of ultrasonic cleaning,this paper introduces the application of ultrasonic cavitation in ship,pipeline and oil cleaning as well as ballast water treatment.By reviewing the existing studies,limitations such as insufficient ultrasonic parameter studies,lack of uniform cleanliness standards,and insufficient cavitation studies are summarized to provide traceable research ideas for improving ultrasonic cavitation technology and to guide the expansion and improvement of its applications.

Nonlinear Backstepping Ship Course Controller

A ship, as an object of course control, is characterized by a nonlinear function describing the static maneuvering characteristics. The backstepping method is one of the methods that can be used during the designing process of a nonlinear course controller for ships. The method has been used for the purpose of designing two configurations of nonlinear controllers, which were then used to control the ship course. One of the configurations took dynamic characteristic of a steering gear into account during the designing stage. The parameters of the obtained nonlinear control structures have been tuned to optimise the operation of the control system. The optimisation process has been performed by means of genetic algorithms. The quality of operation of the designed control algorithms has been checked in simulation tests performed on the mathematical model of a tanker. The results of simulation experiments have been compared with the performance of the system containing a conventional proportional-derivative （PD） controller.

Exploring the potential of graphene materials in marine and shipping industries-A technical review for prospective application on ship operation and material-structure aspects

Advance development of materials technology introduces graphene as a powerful material for various applications in any branch of engineering and industries.Marine and shipping are one of the projected industries which are affected by graphene improvement.The conventional approach of technical manufactures and processes on ship and maritime environments,such as water treatment,oil separation and evacuation,is proven to be developed into more practical ways by utilizing characteristics and properties of graphene-based material.This work is addressed to study graphene as an engineering material in which structural arrangement,mechanical strength,electrical conductivity,and permeability of the material are discussed.Instrumental and cycle applications related to ship operations are defined to be an initial milestone to assess dedicated works in graphene and ship.Potential and future projections based on the works are linked with existing challenges and problems on boards,such as free surface effects and materials coating.Several works showed that graphene-based baffle has the potential to replace the current baffle style in oil tankers and liquid carriers.The electrical conductivity of the graphene is also useful for structural coating for ships that can operate in extremely cold regions,e.g.,the Arctic and Antartica.

10th International Workshop on Ship and Marine Hydrodynamics(IWSH 2017)

The 10th International Workshop on Ship and Marine Hydrodynamics （IWSH 2017） will be held in Keelung, Taiwan, China on November 5-8, 2017. It will be a platform for engineers and researchers to keep abreast of the current scientific and technological advancements in hydrodynamics of marine, ship and ocean engineering and other related fields, including theoretical, numerical and experimental aspects.

Call For Paper The 9th International Workshop on Ship and Marine Hydrodynamics

In 1999,the first International Workshop on Ship Hydrodynamics was successfully held in Wuhan,China.Then it was held in Wuhan,Shanghai,Zhenjiang,Harbin,Seoul in subsequent every two years.These Conferences had drawn a variety of international delegates including scientists,engineers and researchers with a common interest in ship hydrodynamics.
