ABSTRACT Oil exploration and production operations have expanded in the shallow and environmentally sensitive waters in the northeast area of the Caspian Sea, calling for new and innovative methods for oil spill response countermeasures. Water depths as low as 0.6 metres and ice conditions for up to 5 months of the year, present severe planning and response challenges. Agip KCO is in the process of testing air-cushioned vehicles (ACVs)—also commonly referred to as hovercraft, for both Emergency Escape and Rescue (EER) and oil spill response operations. Two such ACVs were sited in the Caspian Sea during 2003 for trials. Tests included boom deployments, skimming operations and general operational criteria. Further trials are planned in 2004, to assess suitability for use within reed bed areas and their benefits over other, more conventional craft in this special operating environment. This paper describes the trials carried out 2003 and their results, together with a review of the issues that are to be addressed

ABSTRACT The first oil field off the coast of Norway initiated production in the early 1970s. Today 33 oil fields are being exploited by the petroleum industry. A further 8 sites are under development, and promising exploration activity is taking place in new areas. Some of these areas are particularly sensitive from an environmental point of view. Since the Bravo blowout in 1977 there has been no major accident involving an oil spill. Overall experience from supervision indicates that petroleum activities are carried out within adequate safety limits. According to the legislative framework for supervision of oil pollution in the petroleum activity, conditions are to be specified by the authorities prior to every exploration and production activity. The design of the recovery system is to be specified by the operator, based on the dimensions of the oil spill. The stipulation is that all production installations can be reached within given response periods, depending on the location of the installation in relation to environmentally sensitive resources. The Norwegian Pollution Control Authority (SFT) is responsible for the national oil spill contingency plan. The petroleum industry shall ensure that its contingency plans are tailored to the actual environmental risk. The environmental authorities have been working on the development of a model to define which regions are to be classified as particularly sensitive. This has led to the implementation of legislation that is of interest to both the industry and the authorities.

<p>A strategy to control the efficiency of a photocleavage reaction based on changing the nature of the excited state is presented. A novel class of photoactive compounds has been synthesized by combining the classical o-nitrobenzyl scaffold with an environmentally sensitive dye, 4-amino-nitrobenzothiazole. Irradiation in a polar solvent lead to an excited state that is inoperative for photochemistry whereas excitation in a nonpolar solvent lead to an excited state that is photochemically active. A photochemical degradation appears to be the preferred process in contrast to the intended photocleavage process.</p>
