“FPSO CYRUS”油船改FPSO方案及技术要点分析

针对"FPSO CYRUS"的改造实例,介绍油船改FPSO中的结构检测、设备拆除翻新、坞内维修、上建改装、甲板改造加强、上部模块与支墩建造安装、货油管系及外输系统改造、火炬塔与多点系泊系统新造等技术要求及其检验注意事项。     

多点系泊FPSO立管支撑结构设计

多点系泊FPSO的首部和尾部均布置有系泊缆,立管通常布置在舷侧中部,因此需要在舷侧安装相应的结构以支撑海底钢悬链线立管（SCR）载荷及甲板上部立管平台和立管提拉设备模块的重量。同时为了防止舷侧立管遭受其他船舶的撞击而发生泄漏和损坏,需要安装立管保护结构。本文以大连船舶重工集团为国外船东设计和建造的一艘30万吨多点系泊FPSO为例,从实际工程设计的角度阐述多点系泊FPSO舷侧立管支撑结构的设计要点,为今后多点系泊FPSO立管支撑结构设计提供借鉴。

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.
