沿海港口驳运船舶如按照沿海航区船舶的稳性要求则难以满足 ,如果按实际航区的情况按遮蔽航区的稳性核算 ,则大多数能满足要求。因此建议对这类船舶的稳性要求应按实际情况予以区别对待 相似文献

文章研究了台山核电厂重要厂用水系统纳潮取水工程。根据实测资料分析了自然条件和岸滩演变。分别建立了工程海区二维波浪、潮流、泥沙数学模型,并根据实测资料对夏季和冬季全潮水文进行了验证。在经验证的数学模型基础上,研究了重要厂用水系统纳潮取水工程实施后的潮流变化及泥沙回淤情况。结果表明,重要厂用水系统纳潮取水工程实施后,流场变化仅局限于安全取水工程附近小范围海域,进水前池附近水域泥沙年冲淤和骤淤都不大。因此,从潮流、泥沙角度考虑,重要厂用水系统纳潮取水工程是可行的。 相似文献

随着科技信息手段不断进步,通过信息化手段实现对船舶的远程检验已在部分国际知名船级社成为现实,并取得良好社会反响。随着《船舶安全监督规则》及相关配套文件的出台,作为海事监管核心业务之一的船舶安全检查工作,在实际工作中面临一些新问题,尤其是对船旗国监督检查(FSC)复查的要求变化较大。随着国家简政放权、大力提高政府效能相关理念的提出,笔者结合工作实际,提出在船旗国监督检查复查时采取远程复查方式构想和建议,希望对进一步提升海事执法效能,更好服务港航经济发展有所借鉴和帮助。 相似文献

The aim of this research is to develop an algorithm and application that can perform real-time monitoring of the safety operation of offshore platforms and subsea gas pipelines as well as determine the need for ship inspection using data obtained from automatic identification system(AIS). The research also focuses on the integration of shipping database,AIS data, and others to develop a prototype for designing a real-time monitoring system of offshore platforms and pipelines. A simple concept is used in the development of this prototype, which is achieved by using an overlaying map that outlines the coordinates of the offshore platform and subsea gas pipeline with the ship's coordinates(longitude/latitude) as detected by AIS. Using such information, we can then build an early warning system(EWS) relayed through short message service(SMS), email, or other means when the ship enters the restricted and exclusion zone of platforms and pipelines. The ship inspection system is developed by combining several attributes. Then, decision analysis software is employed to prioritize the vessel's four attributes, including ship age, ship type, classification, and flag state.Results show that the EWS can increase the safety level of offshore platforms and pipelines, as well as the efficient use of patrol boats in monitoring the safety of the facilities. Meanwhile, ship inspection enables the port to prioritize the ship to be inspected in accordance with the priority ranking inspection score. 相似文献
