Learning to Run

In Africa, there live antelopes and lions.In the morning, the antelope wakes up from sleep. His first sense is that he has to run faster than the fastest lion, otherwise, he will be eaten out. In the meanwhile, when the lion opens his eyes, his first thought is he must run faster than the slowest antelope,otherwise, he will starve to death.

SUMMARY

Animals run fast on instinct, however, before running large state-owned enterprises must ponder over the questions of where to run and how to run. As far as the speaker＇s long-term experience concerned, to be the fastest and best runner, five basic skills are indispensable before the running. These five skills are discussed in five parts in the essay as follows： Global Vision -- Requirement of Global Competition, Strategic Thought -- the Key to Be Advantageous, Study of Rules -- Guideline of operational Activities, Reform Deepening -- Impetus for Persistent l..eade~hip, Scientific Development -- Soul to Pursue Preeminence.     

Model and algorithm for container ship stowage planning based on bin-packing problem

In a general case, container ship serves many different ports on each voyage. A stowage planning for container ship made at one port must take account of the influence on subsequent ports. So the complexity of stowage planning problem increases due to its multi-ports nature. This problem is NP-hard problem. In order to reduce the computational complexity, the problem is decomposed into two sub-problems in this paper. First, container ship stowage problem （CSSP） is regarded as “packing problem”, ship-bays on the board of vessel are regarded as bins, the number of slots at each bay are taken as capacities of bins, and containers with different characteristics （homogeneous containers group） are treated as items packed. At this stage, there are two objective functions, one is to minimize the number of bays packed by containers and the other is to minimize the number of overstows. Secondly, containers assigned to each bays at first stage are allocate to special slot, the objective functions are to minimize the metacentric height, heel and overstows. The taboo search heuristics algorithm are used to solve the subproblem. The main focus of this paper is on the first subproblem. A case certifies the feasibility of the model and algorithm.     

Risk zone of wrack hitting marine structure simulated by 2D hydraulic model

The wrack or the ship out of control will drift with flow.One of the most important factors that drive the ship is flow current which moves circularly in tidal area.The wrack from same place always drifts in different ways if the start time is different.So,during the ship drifting period,the drift trace is also determined by both wave and wind forces.The drift direction is limited by water depth which must be deeper than ship draft. These marine structures that can not afford the hit of wrack or will destroy the wrack must be well considered when they are placed near harbor and waterway or other water area with ship running.The risk zone should be consulted according to tide and weather conditions to protect structures and ships in necessary.A method is presented here to simulate the risk zone by 2D numerical hydraulic model with tidal current,wave,wind and water depth considered.This model can be used to built early-warning and protect system for special marine structure.     

加强内地与香港交通合作 发挥香港国际航运中心作用

<正>Dear readers,welcome to read this issue of our jour-nal,Ports of China.The Chinese Government is going to resume exercis-ing sovereignty over Hong Kong.This is a grand eventthat has been drawing world attention.The port in HongKong is one of the busiest ports of the world,ranking asthe world’s biggest container port for five consecutiveyears.Therefore,Hong Kong’s return to the motherlandis a significant event for the Chinese ports industry aswell.In order to celebrate this epoch-making event,weare opentng a special column in this issue,Hong KongComing Back.For this column,Mr.Huang Zhendong,Minister of Communications,sent us his essay,entitled"Strengthening Cooperation Between Hong Kong and theInland Areas in Communications,Mobilising HongKong’s Functions as an International Shipping Center".Mr.Li Weizhong,President,China Ports and HarborsAssn,Also contributed his essay "Hailing Hong Kong’sReturn That Has Wiped Out the Old Humiliation,Look-ing out for a Better Megaport in the Future".also run inthis c     

A porous cell method for the simulation of fluid-solid interactions

There are many ways of describing a solid,porous or fluid region of the computational domain when solving the Navier-Stokes equations(NSE)for flow motions.Amongst these the porous cell method is one of the most flexible approaches.In this method,a parameter is defined as a ratio of the volume open to water and air in a calculation cell to its cell volume.In the calculation,the same numerical procedure is applied to every cell and no explicit boundary conditions are needed at solid boundaries.The method is used to simulate flow through porous media,around solid bodies and over a moving seabed.The results compare well with experimental data and other numerical results.In our future work the porous cell method will be applied to more complex fluid-solid interaction situations.     

滑行艇高速航行时的数值模拟(英文)

Planing vessels are applied widely in civil and military situations.Due to their high speed,the motion of planning vessels is complex.In order to predict the motion of planning vessels,it is important to analyze the hydrodynamic performance of planning vessels at high speeds.The computational fluid dynamic method(CFD) has been proposed to calculate hydrodynamic performance of planning vessels.However,in most traditional CFD approaches,model tests or empirical formulas are needed to obtain the running attitude of the planing vessels before calculation.This paper presents a new CFD method to calculate hydrodynamic forces of planing vessels.The numerical method was based on Reynolds-Averaged Navier-Stokes(RANS) equations.The volume of fluid(VOF) method and the six-degrees-of-freedom equation were applied.An effective process was introduced to solve the numerical divergence problem in numerical simulation.Compared with experimental results,numerical simulation results indicate that both the running attitude and hydrodynamic performance can be predicted well at high speeds.     

Maritime Safety Through Systems Safety Engineering

1.INTRODUCTION In current semmars and conferences about marine transportation safety and shipping safety, the Internationsl safety Code(ISM)is one of the hot topics. In this paper the authors introduce the concepts Of systems safety engineering(SSE). The historical backgrounds of both ISM and SBE are described. The authors compare the concepts of both ISM and SSE. The advantages of SSE are discussed. The authors also introduce the SSE programme plan and SSE activities. 2.DEFINITIONS OF SAFETY If we look for the definition Of safety in an English dictionary, it tells you that safety is a noun meaning a state of being free from harm or danger. To expand the dictionary definition technically, we might define safety as "A measure that determines to what extend the management, technology and operation of a system is free from danger to life, property and the environment".
