基于协同的集装箱多式联运协调问题的研究

集装箱多式联运系统是一个复杂的运输工程系统,其组织协调工作仍存在严重不足,多式联运系统应具有的整体效果不能充分发挥。因此,只有各运输方式之间和参与多式联运的企业之间相互协同合作,才能达到联运全程系统化,实现多式联运的综合效益。本文对集装箱多式联运发展中存在的协调问题及影响因素进行分析,应用协同管理理论进行研究,对多式联运组织系统协调发展具有一定的理论指导作用。     

多点系泊起重船数值分析与试验对比研究

以一艘工作水深46m的现役起重船为研究对象,采用基于全QTF法的时域准静态分析法对实际尺度起重船与系泊系统进行耦合数值分析,并与1:50的模型试验结果进行比较。结果表明:由于不考虑粘性阻尼影响,纵荡、纵摇的计算结果偏大,垂荡运动计算结果较为可信;垂荡、纵摇运动具有一阶低频成分,该响应对起重船的作业安全具有一定的威胁,应当给予重视;粘性阻尼、缆绳动力响应与水深对系泊起重船运动与缆绳张力的影响还有待研究。     

An empirical model for estimating berth and sailing times of mega container ships

ABSTRACT

We provide two empirical models for calculating the sailing time and berth time of maritime container liner networks to effectively model the ambiguity associated with sea and port contingency for ex-ante decisions of fleet deployment and route planning. The models are based on recorded AIS data of 110 mega vessels including all the operating container mega vessels with a capacity of 16,000 TEU or more during the summer of 2015. The models are able to estimate the sailing time (with R² of 0.974) and the berth time (with R² of 0.895) without knowledge of any operational-level explanatory variables. The models are validated against the published East Asia–North Europe services. Moreover, the study reveals that vessel operators adopt different berthing and sailing strategies even under the same conditions.

Ultimate strength of container ships subjected to combined hogging moment and bottom local loads part 1: Nonlinear finite element analysis

This paper is the first of two companion papers concerning the ultimate hull girder strength of container ships subjected to combined hogging moment and bottom local loads. In the midship part of container ships, upward bottom local loads are usually larger than the downward ones. This leads to the increase of biaxial compression in the outer bottom plating and the reduction of the ultimate hull girder strength in the hogging condition. In this Part 1, the collapse behavior and ultimate strength of container ships under combined hogging moment and bottom local loads are analyzed using nonlinear finite element method. Buckling collapse behavior of bottom stiffened panels during the progressive collapse of a hull girder is closely investigated. It has been found that major factors of the reduction of ultimate hogging strength due to bottom local loads are (1) the increase of the longitudinal compression in the outer bottom and (2) the reduction of the effectiveness of the inner bottom, which is on the tension side of local bending of the double bottom. The obtained results will be utilized in the Part 2 paper to develop a simplified method of progressive collapse analysis of container ships under combined hogging moment and bottom local loads.
