ABSTRACT
Motivated by two greater oil spills in 1981 and 1982 with total cleaning costs of about $11 million, the Free and Hanseatic City of Hamburg developed in 1983 a complete oil spill contingency plan with a detailed environmental sensitivity map. This book concerns the Elbe River inside the boundaries of Hamburg and, of course, the harbor region, which covers about 87 km2. The contingency plan is called Ölunfall—Handbuch (Oil Spill Handbook). It starts with general remarks about the physical and chemical characteristics of oil. Especially, there are lists of imported and exported crude oil and oil products in the Hamburg Harbor complete with lists of important parameters for combating the effects of these oils and products. This is followed by chapters dealing with the behavior and characteristics of oil after a spill, and the classification and identification of oil. Some analytic methods for in situ measurements are listed. Safety measures during combating actions are followed by a general discussion of combating methods such as various booms, skimmers, pumps, chemicals, and interim depots.
Simulations and experiments were carried out to get better knowledge of the hydraulic conditions and to enable predictions, especially in the streamed harbor basins. The contingency plan details the notification and mobilization of the command team of the government environmental agency, the mainly scientific support teams, and the private action team.
Environmental sensitivity maps have been developed to help the command team identify priority areas for maximum effort for combating actions. The system includes 18 general profiles, which describe the location of beaches and quays in Hamburg with a sensitivity scale from 2 to 10 with respect to the cleanup possibilities in oil spills. The maps also show if combating has to be done only from the water side, where there are ramps and cranes for loading ships with equipment, and prepared places for OSC containers. Most important are the areas of ecological significance marked by symbols of the types of birds, plants, fish and benthos with symbols for the time of year they will be there. Finally, 162 points are designated for which special recommendations are given for combating actions, including remarks about needed facilities, staff, and times to arrive.
