针对传统海洋平台消防灭火方式存在的不可持续性、灭火介质的有害性等问题,提出在半潜式修井及生活平台Delta CAT500上采用高压细水雾灭火系统。该系统在一定的高压条件下经过特殊喷嘴喷射出水雾,喷出后与外部空气充分卷吸、破碎、雾化产生很小的高速均匀细水雾,从而增大水粒与热源的作用表面积并降低一定范围内的氧气含量来达到良好的灭火目的。经实船应用证明:与泡沫、二氧化碳等灭火系统相比,高压细水雾灭火系统具有较强的稳定性和可持续性,是一种安全、清洁、环保、高效的灭火系统。 相似文献

针对船坞在非注水状态下,在建邮轮根据不同工况进行冷却水系统调试时,提供足量冷却水,并保证邮轮海水缓冲舱内水压低于最大设计承压的问题,以国内首制豪华邮轮的冷却水系统调试需求为例,针对邮轮设备和系统冷却水系统的冷却水需求量和工作压力,分析计算供水量和压力的影响因素,提出冷却水系统调试装置的设计方案,确定冷却水供给量和压力的技术参数。分析结果表明,江水潮位对船坞内邮轮冷却水系统的调试具有很大的影响,低潮位时会造成供水量和压力不够,高潮位是则会造成邮轮设备和系统超压,提出的方案可以有效解决上述问题。 相似文献

This paper considers port infrastructure, in terms of the physical limitations placed on vessel size, at the major cruise ship ports in northern Europe. Physical design characteristics and vessel size restrictions common to these ports are identified. The same physical design charactersitics and vessels limitations are considered in the context of a port with cruise ship ambitions, viz. Leith. The subsequent analysis suggests that infrastructure design weaknesses at a given port, in this case the presence of an entrance lock and tidal delay, may act as a deterrent to cruise ships. Primary data gathered from cruise lines and from observation of cruise ship activity at Leith supports this hypothesis. These findings have implications for both seaports and cruise lines. 相似文献

This paper provides an estimation of air emissions (CO2, NOX, SOX and PM) released by cruise vessels at the port level. The methodology is based on the “full bottom-up” approach and starts by evaluating the fuel consumed by each vessel on the basis of its individual port activities (manoeuvring, berthing and hoteling). The Port of Barcelona was selected as the site at which to perform the analysis, in which 125 calls of 30 cruise vessels were monitored. Real-time data from the automatic identification system (AIS), factor emissions from engine certificates and vessel characteristics from IHS Sea-web database were also collected for the analysis. The research findings show that the most appropriate indicators are inventory emissions per “port-time gross tonnage”, “port-time passenger” and “port time”. These emission indicators improve our understanding of cruise emissions and will facilitate the work that aims to estimate reliably and quickly the in-port ship emission inventories of cruise ports. 相似文献

The cruise ship industry is currently undergoing a period of rapid expansion. New cruise capacity threatens to produce overtonnaging, with future berths exceeding demand. Despite this development, cruise operators are confident that a growing North American market will be able to satisfy the equilibrium condition sought by vessel operators. This research explores where the new tonnage might be deployed and its eventual impact on the cruise industry. Geographic concepts are utilized to test and support the premise that geography contributes positively to the cruise port selection process. Itineraries, influenced by ‘site’ and ‘situation,’ are presently still the most important factor affecting cruise port selection. 相似文献
