MEPC.107(49)决议中有关船舶机器处所舱底水防污染设备要求的疑点及研究

MEPC.107(49)决议《修订的船舶机器处所舱底水防污染设备指南和技术条件》被MARPOL公约附则I纳入强制性,该决议为WPSC检查船舶舱底水防污染设备提供一个基本指导,随着PSC检查工作的逐步深入,发现该决议对有效防止船员蓄意或误操作而造成非法排放仍未能给予明确要求,本文结合PSC检查实例对决议要求的疑点进行详细探讨和研究。     

MEPC.107(49)决议中防备蓄意操控15×10~(-6)舱底水报警装置要求

正0引言《经1978年议定书修订的1973年国际防止船舶造成污染公约》(《73/78防污公约》)附则Ⅰ第14条是关于船舶防污染设备的。该条规定400总吨及以上的船舶应安装经认可的机器处所舱底水处理设备,10 000总吨及以上的船舶还应安装经认可的15×10~(-6)(10~(-6)=1 ppm)舱底水报警装置和自动关停装置,当舱底水分离器流出物的含油量高于     

船舶舱底水蓄意排放风险分析及建议

MEPC.107(49)决议通过技术上的改进在一定程度上防止了船员蓄意操纵设备违规排放舱底水这类事件的发生,并且为PSCO检查舱底水防污染设备提供了基本指导。但随着PSC检查工作的深入,却发现决议存在不足,船员仍然可以通过蓄意操纵来违规排放舱底水。介绍符合MEPC.107(49)决议15 ppm舱底水报警设备实现防蓄意操纵功能的原理,以及存在违规排放舱底水的风险隐患,并针对存在的风险提出修订MEPC.107(49)决议的建议。     

符合MEPC.107(49)决议要求的两种新型油水分离器

机舱含油污水,多年依靠常规的两级油水分离器使排出水含油低于15 ppm。近年来,船舶燃、润油广泛使用多种添加剂,机舱含油污水中含有更多性能相对稳定的化学乳化油,因而靠常规的二级油水分离器分离难度增大,分离效果变差。国际海事组织意识到超标排放的可能性、普遍性和严重性,第49次环保会通过了MEPC.107(49)决议《船舶机器处所舱底水防污染设备指南和技术条件》,     

舱底油污水分离器试验系统自动控制

针对国际海事组织海洋环境保护委员会IMO MEPC.107(49)决议15PPM舱底油污水分离器必须适用于可能会含有渣油、轻油和乳化油的油性舱底水的要求开发了新型15PPM舱底油污水分离器,该试验系统由于采用了PLC可编程序控制器及序批、时钟、连续和自动化设计,使试验系统混合液配比实现了实时自动化控制。经过中国船级社型式认可试验,证实其先进性、可靠性和必要性。     

中国船级社发布压载水系统型式认可指南

正为了执行《国际船舶压载水及沉积物控制和管理公约》的相关规定,并按照国际海事组织(IMO)制定的压载水处理系统认可导则中对压载水处理系统进行型式认可的规定,中国船级社近日发布了《压载水系统型式认可指南》(以下简称"《指南》")。     

关于MEPC.60（33）决议的几点探讨

MEPC.60(33)决议及其批准的《船舶机舱舱底水防污染设备导则和技术条件》是92年10月30日通过的,它替代了原A.393(X)决议。凡从事船舶油污染防治工作的同事,包括主管机关、设计单位、制造厂和用户都必须学习好MEPC.60(33)及《导则和技术条件》,了解MEPC.60(33)与A.393(X)之间存在的主要差异,并正确理解付诸实施。 笔者在学习该《导则和技术条件》时,有如下几点看法提出供讨论:

Recent progress on wave induced loading measurements in warships

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.
