废钢船拆解业是一种高利润、高风险的行业,同时废钢船拆解也给周围环境及生态资源带来严重威胁。为了减轻船舶拆解对环境和生态的危害,主管部门从拆船厂的设立、废钢船拆解的作业许可、拆解安全、防止拆船污染及拆船人员保护等方面加强控制和管理,最终达到绿色拆解、无害拆解的目标。 相似文献

今年前三季度,我国拆船企业拆解废船量与去年同期基本持平,但由于废钢价格同比大幅降低,企业效益大幅下滑,废钢大量积压,行业出现全面亏损。中国拆船协会副会长兼秘书长吴军分析称,今年第四季度拆船业或将延续前三季度的行情,全行业将面临全年亏损的大势已基本确定。 相似文献

Marine ecosystem models are becoming increasingly complex and sophisticated, and are being used to estimate the effects of future changes in the earth system with a view to informing important policy decisions. Despite their potential importance, far too little attention has been, and is generally, paid to model errors and the extent to which model outputs actually relate to real-world processes. With the increasing complexity of the models themselves comes an increasing complexity among model results. If we are to develop useful modelling tools for the marine environment we need to be able to understand and quantify the uncertainties inherent in the simulations. Analysing errors within highly multivariate model outputs, and relating them to even more complex and multivariate observational data, are not trivial tasks. Here we describe the application of a series of techniques, including a 2-stage self-organising map (SOM), non-parametric multivariate analysis, and error statistics, to a complex spatio-temporal model run for the period 1988–1989 in the Southern North Sea, coinciding with the North Sea Project which collected a wealth of observational data. We use model output, large spatio-temporally resolved data sets and a combination of methodologies (SOM, MDS, uncertainty metrics) to simplify the problem and to provide tractable information on model performance. The use of a SOM as a clustering tool allows us to simplify the dimensions of the problem while the use of MDS on independent data grouped according to the SOM classification allows us to validate the SOM. The combination of classification and uncertainty metrics allows us to pinpoint the variables and associated processes which require attention in each region. We recommend the use of this combination of techniques for simplifying complex comparisons of model outputs with real data, and analysis of error distributions. 相似文献

Shipping is a high-risk industry. The aims of this conceptual paper are to build a framework showing in what way safety onboard is influenced by trust, and to identify the main obstacles to trust-building within the shipping industry. To meet these aims, a literature review and a pilot study are conducted. The study shows that interpersonal trust from employees to managers, and among seafarers, seems to be a prerequisite and an indirect factor, or mediating variable, that influence safety-related organizational outcomes positively and seems to reduce human errors. Interpersonal trust seems to be most valuable in weak situations, which means situations that are not critical and when no exact guidance or incentives to behave in a particular way are needed. An optimal level of trust exists onboard, and because of the high-risk environment, this optimal level of trust is expected to be relatively high. The main obstacles to trust within the shipping industry seem to be the dual employment practice, the physical distance between onboard, crewing agency and onshore, the reduced competence requirements, the frequent reorganization of the crew and multiculturalism. The paper contributes to the trust and to the safety literature by a new framework and to the development of 11 hypotheses on trust and safety. Finally, the paper is indicating that trust may be the missing piece in the safety puzzle. 相似文献

在双向曲率板线加热成型及滚压成型的工艺设计研究中,一项十分重要的工作就是依据所需目标形状计算应变分布并以此确定加工路径和工艺参数,因此应变分布计算的精度直接影响到加工路径和工艺参数的准确性.本文介绍了一种基于力学方法的应变分布计算方法,首先对平板施加节点位移场进行弹塑性计算,由于存在回弹现象,需对节点位移场进行反变形修正,本文将得到的形状与目标进行对比后,再利用两者偏差对位移场进行迭代修正,直到两者偏差满足精度要求,最后将得到的应变场以初应变的形式输入到平板模型上,用初应变法的结果对应变的计算方法进行验证,证明该方法的精度,为后续加工路径和工艺参数的准确确定提供基础. 相似文献

以某国内大型风电平台上层建筑分段吊装为例,对新设计的一体式上层建筑分段进行吊装方案编制并借助有限元计算软件进行方案校核。在吊装计算中,主要从2个方面进行考虑:一是如何高质量地完成计算分析,保证计算符合实际情况,得到真实的结构响应;二是对吊装布置和加强方案进行分析,根据有限元分析结果为基地建造部门提出建议,保证吊装方案科学合理。给出一种新的有限元分析方法,并比较其与常规方法的加载方式。比较2种方法的计算结果,验证新方法可真实有效地模拟吊装的受力情况。分析结果可为造船企业今后提升海洋平台建造分段吊装工艺水平提供参考和借鉴。 相似文献
