Risk analysis of vessel traffic systems

A risk analysis approach to the capital planning of vessel traffic services (VTS) is embedded within the benefit-cost methodology. The method is discussed in the Canadian context, but has already been used to plan the Hong Kong VTS system. Recently, in response to the Exxon Valdez oil spill, the US Congress asked for a study of the requirements for VTS systems in American ports and waterways, and the US Coast Guard chose to apply our risk analysis approach to their study.

The passenger vessel services act and America's cruise tourism industry

The Passenger Vessel Services Act (PVSA) of 1886, a cabotage law, attempts to shield U.S. maritime shipping from foreign competition. It also applies to the U.S. cruise ship industry. The PVSA requires foreign cruise ships that carry passengers between U.S. ports to also stop at foreign ports. Norwegian Cruise Line America (NCLA), which operates one U.S. flagged cruise ship in Hawaii, wants the U.S. Customs and Border Protection to require foreign cruise ships offering Hawaii itineraries from the U.S. west coast to spend more time in foreign ports. We analyze the merits of NCLA's proposal. We argue that rather than making the PVSA even more protectionist, the law should be repealed.

船舶高粘度空压机油的研制

进口船舶专用空压机上使用一种高粘度空压机油.该油品国内无成熟产品可替代,为了满足该类空压机的用油需求,必须对这种高粘度空压机油进行国产化研制.研究中根据进口空气压缩机组工作条件和国外相应油料技术要求,制定了国产油料的产品规范,并以聚α-烯烃合成油和加氢矿物油复合为基础油,通过加入多种功能添加剂,研制了一种新油品.通过理化性能试验、积炭生成倾向台架试验和使用寿命全尺寸台架试验,对研制油品和进口油料进行了对比试验.试验结果表明,研制产品理化性能达到了进口产品指标要求,积炭倾向性符合L-DAB标准要求,使用寿命达到中高负荷往复式空压机油所规定的换油周期和使用要求,研制油品综合性能完全达到国外同类参比油的性能,满足进口空压机的使用要求,可代替进口油料在引进装备上使用.

Post OPA-90 vessel oil spill differentials: transfers versus vessel accidents

This study investigates vessel oil spill differentials for transfer and vessel-accident spills for the post Oil Pollution Act of 1990 (OPA-90) period. In-water and out-of-water transfer/vessel-accident oil spill equations are estimated, utilizing tobit regression analysis and data of individual vessel oil spills (of oil-cargo and non-oil-cargo vessels) investigated by the US Coast Guard for the 1991-1995 period. In the data, 47.5% (94.1%) of in-water (out-of-water) gallons of oil spilled were transfer spills; non-oil-cargo vessels accounted for 44.2% of all gallons spilled. The estimation results suggest that out-of-water transfer spills are larger in size than vessel-accident spills, but are similar in size for in-water spills. Transfer/vessel-accident spill differentials exist (do not exist) among determinants of in-water (out-of-water) spills. The policy implication of the results is that a vessel oil spill-reduction differentiation regulatory regime is needed that differentiates between transfer and vessel-accident spills and in-water and out-of-water spills for reducing vessel oil spills.

Vessel traffic service systems: cost-recovery alternatives

This paper investigate cost-recovery alternatives for US federally-operated vessel traffic service (VTS) systems. These include those currently used or have been used by VTS and 'VTS-like' systems and other feasible, but not used herefore, alternatives, a federal trust and a federal VTS user-fee structure. Three federal trust funds exist whose waterway-related earmarked revenues could also be earmarked for VTS systems. A federal VTS user-fee structure while raising revenue to finance VTS systems is not expected to be detrimental to the competitiveness of VTS ports nor to the vessel operators that call if their cost-savings exceed fees paid.
