Oil Spill Cleanup

ABSTRACT Oil spill cleanup systems using side-fitted sweeping booms are developed to operate offshore with minimal requirements for vessels and personnel. The system takes advantage of the boundary layers created by the oil recovery vessel, thus simplifying the handling of booms, skimmers, and the oil recovery operation itself.

Oil Spill Cleanup

Both classical and new marine oil spill cleanup response methods and techniques are discussed. The intention is mainly to answer the fundamental questions of when, where, and how to apply the different methods. A brief review of the stages of the oil spill response problem is first presented, followed by the factors that influence the different methods. This is followed by an analysis of some new cleanup methods and improvements to existing methods, specifically: bioremediation, the use of more efficient ships for skimming, the use of fishing nets for heavy oil recovery, and new materials and designs of sorbents. Some cases are also analyzed to evaluate the performance of some methods under real conditions.

Probabilistic Nature

ABSTRACT A computer simulation program has been developed to aid in the evaluation of the oil-spill contingency plans for offshore operations. Using this program, the performance of oil-spill recovery equipment can be simulated as a function of oil-spill size, spill location, and weather. The unique feature of the program is its ability to predict oil recovery as a function of weather conditions. The weather data used consist of the historical wave height frequency distribution and wave height persistence. The oil thickness, which is determined by spreading of the oil, and the wave state determine the performance of recovery equipment. When using the program, oil-spill events and cleanup operations are simulated many times. Each time the weather conditions used in the simulation will be different, owing to the probabilistic nature of weather in the real world and the use of random access to the weather data. In this way a probabilistic estimate of oil recovery is produced for any given oil-spill incident and equipment array. Simulations are presented using state-of-the-art equipment, although the use of improved equipment can be simulated. The results show the need for rapid response and for containment for sudden spills due to the rapid thinning of uncontained oil.
