Abstract

Ships for drilling need to operate in the territorial waters of many different countries which can have different technical standards and procedures. For example, the European Union and European Economic Area EU/EEA product safety directives exclude from their scope drilling ships and related equipment onboard. On the other hand, the EU/EEA offshore safety directive requires the application of all the best technical standards that are used worldwide in the oil and gas industry. Consequently, it is not easy to select the most appropriate technical standards that increase the overall level of safety and environmental protection whilst avoiding the costs of additional certifications. We will show how some technical standards and procedures, which are recognized worldwide by the petroleum industry, can be accepted by various standardization bodies, and how they can fulfil the essential health and safety requirements of certain directives. Emphasis will be placed on the prevention of fire and explosion, on the safe use of equipment under pressure, and on the protection of personnel who work with machinery. Additionally considered is how the proper use of adequate procedures available at the time would have prevented three large scale offshore petroleum accidents: the Macondo Deepwater Horizon in the Gulf of Mexico in 2010; the Montara in the Timor Sea in 2009; the Piper Alpha in the North Sea in 1988.

Abstract

Over the last decade maritime transport in the Gulf of Finland area has changed significantly. The disintegration of the Soviet Union forced Russia to start developing its own Baltic ports and terminals and to find new routes to export its oil. The Baltic States have enjoyed a remarkable economic boom, especially regarding new port and terminal development and oil transportation. Due to the fact the Gulf of Finland is a sensitive brackish water area with a unique nature and environment, there has been a growing concern with accidental oil spills and various negative impacts caused by the maritime transport. Previous large-scale accidents elsewhere may have been the driving forces behind both the publicity and the calls from experts for new requirements to improve maritime safety and develop preventive measures against future accidents. This report, commissioned by the Finnish Ministry of the Environment is an updated report of the earlier study on the Gulf of Finland's oil transport, published in 1999. The rapid changes in the oil business, new terminals and enlarging transport figures were the driving forces for updating this work. The report contains statistics on oil transport, terminal development, and it presents future development scenarios up to 2010. Much emphasis has been placed on safety-related activities and recommendation; therefore current activities to improve the safety and/or develop better oil spillage-combating measures have also been analysed and discussed.

Abstract

prototype for an operational ship routing Decision Support System using time-dependent meteo-oceanographic fields is presented. The control variable is ship course, which is modified using a directional resolution of less than 27 degrees. The shortest path is recovered using a modified Dijkstra’s algorithm. Safety restrictions for avoiding surfriding and parametric rolling according to the guidelines of the International Maritime Organization (IMO) are implemented. Numerical experiments tailored on a medium-size vessel are presented and perspectives of development of the system are outlined.
