Oil spills from maritime activities can lead to very extensive damage to the marine environment and disrupt maritime ecosystem services. Shipping is an important activity in the Northern Baltic Sea, and with the complex and dynamic ice conditions present in this sea area, navigational accidents occur rather frequently. Recent risk analysis results indicate those oil spills are particularly likely in the event of collisions. In Finnish sea areas, the current wintertime response preparedness is designed to a level of 5000 tonnes of oil, whereas a state-of-the-art risk analysis conservatively estimates that spills up to 15000 tonnes are possible. Hence, there is a need to more accurately estimate oil spill scenarios in the Northern Baltic Sea, to assist the relevant authorities in planning the response fleet organization and its operations. An issue that has not received prior consideration in maritime waterway oil spill analysis is the dynamics of the oil outflow, i.e. how the oil outflow extent depends on time. Hence, this paper focuses on time-dependent oil spill scenarios from collision accidents possibly occurring to tankers operating in the Northern Baltic Sea. To estimate these, a Bayesian Network model is developed, integrating information about designs of typical tankers operating in this area, information about possible damage scenarios in collision accidents, and a state-of-the-art time-domain oil outflow model. The resulting model efficiently provides information about the possible amounts of oil spilled in the sea in different periods of time, thus contributing to enhanced oil spill risk assessment and response preparedness planning.

海上活动造成的溢油可能对海洋环境造成非常广泛的破坏,并扰乱海洋生态系统服务。航运是北波罗的海的一项重要活动,由于该海域冰况复杂多变,航行事故频发。最近的风险分析结果表明,在发生碰撞的情况下,这些石油泄漏的可能性特别大。在芬兰海域,目前的冬季应对准备设计为5000吨石油的水平,而最先进的风险分析保守估计,泄漏可能高达15000吨。因此,有必要更准确地估计北波罗的海的溢油情况,以协助有关当局规划反应船队的组织及其业务。在海上航道溢油分析中,有一个尚未得到重视的问题是溢油的流出动力学,即溢油的流出程度如何随时间而变化。因此,本文将重点研究在北波罗的海作业的油轮可能发生的碰撞事故的溢油情景。为了估计这些,开发了一个贝叶斯网络模型,该模型集成了在该地区运行的典型油轮的设计信息、碰撞事故中可能发生的损坏情况的信息以及最先进的时域油流出模型。由此产生的模型有效地提供了不同时期海上可能溢油量的信息,从而有助于加强溢油风险评估和应急准备规划。Floris Goerlandt是位于芬兰埃斯波的阿尔托大学工程学院海洋技术部门的一名研究员。他在比利时根特大学(University of Ghent)获得机电工程硕士学位,辅修海洋技术。随后,他在比利时安特卫普大学和根特大学的联合项目中获得海事科学硕士学位。他以优异的成绩获得芬兰阿尔托大学(Aalto University)的科学博士学位,研究课题为“海上运输中的风险分析:原则、框架和评估”。在此期间,他曾在比荷卢、挪威、新加坡和中国的运营船舶和建造造船厂担任船体认证工程师和验船师,获得了广泛的国际经验和技术专长。戈兰特博士是海事风险和安全领域的活跃研究人员。他是ICES波罗的海海事风险工作组和风险分析学会应用风险管理专业小组的成员。他曾多次担任国际海事组织代表,并担任《安全科学》特刊《风险分析、验证和风险管理中的信任》的客座编辑。他发表了60多篇同行评议的期刊和会议文章,主题涉及事故分析、水路风险分析、海上安全管理、船舶运营风险降低工具和风险分析的基础问题。

The presented work is an experimental investigation into the waves generated by a pressure source moving in a straight channel. Wave fields generated by the moving pressure source are described and the effects of angle of attack on the generated wave height, surfable wave quality, drag and vertical forces are presented. The main objective of this study was to investigate the relationship between the angle of attack and the generated wave height across the towing tank width and the surfable wave quality. The investigations were conducted at the Australian Maritime College towing tank on a wavedozer at four different attack angles at various speeds. Three wave probes were installed across the channel to record the generated wave heights. Based on the experimental results, it was concluded that smaller angles of attack produced higher quality surfable waves compared to larger angles of attack, while the height of the generated wave has a direct relationship with the angle of attack. By comparing the forces for different models, it was concluded that the pressure source with the lowest angle of attack has the minimum drag but maximum displacement.

This paper presents an overview of ship traffic volume and accidents in the Baltic Sea with a special focus on the Gulf of Finland. The most common accidents are groundings and collisions, usually reported to be caused by human error. The annual number of Baltic Sea accidents reported to HELCOM varied from 34–54 for collisions and 30–60 for groundings. The number of yearly port calls varied from 468–505 thousand with a peak in 2008. Exact port call data could not be found for all ports and hence had to be estimated. The number of line crossingings in HELCOM AIS data was found to be a good, rough surrogate measure for the total number of port calls and could be used if more precise port call data was not available. By analyzing two separate accident databases, an estimate for accident underreporting was calculated. Different statistical methods yielded an underreporting rate in the range of 40–50%. Lastly, the true number of accidents was estimated, based on the estimated underreporting percentage for the Baltic Sea. Based on these results, the true number of true accidents should be first estimated if accident statistics are used in building or validating maritime risk models. When using such models or accidents statistics in decision-making, the underlying uncertainty in the accident statistics should be taken into account as the underreporting frequency estimates are only approximations of the real number of accidents.

Today, almost 80% of cargo is transported by sea. Most of the global maritime shipping operations are performed in the direction East – West, through the southern routes, i.e. Singapore - Suez Canal - Gibraltar - Europe. The total fuel cost is the major concern and the main drawback of these routes. According to the latest statistics and analyses, the price of fuel is growing and such a trend will cause a great impact on the economies of developing countries. For these reasons, new alternative maritime routes, in which the optimization of transportation in the maritime transport network can be achieved, are to be found. There is a possibility of establishing such routes in the areas of high latitudes where climatological changes and diminishing ice open up entirely new possibilities for shipping and present completely new challenges in the global shipping industry. Through the comparative analysis of the main routes and the SWOT method, this paper discusses the advantages, potential and importance, as well as the level of reliability, threats and disadvantages of using the areas of high latitude in maritime transport.
