Design And Construction

The planning, design and construction of two offshore exploratory drilling islands, constructed in the Alaskan Beaufort Sea during the summer of 1980, is described. Emphasis is given to areas of the work that are either unique to the Alaskan Beaufort Sea or involve modifications to the artificial island technology developed in the Canadian Beaufort Sea. The construction of the islands using a land gravel source, transport and handling of the gravel by highly efficient equipment, and placement of the gravel using the limited marine equipment available at Prudhoe Bay is described. The development of an economical slope protection system, with a design life of 3 yr, in Arctic environment and the monitoring and maintenance program planned to minimize the propagation of anticipated damage and maximize the effectiveness of the slope protection system is described, and knowledge gained to date is also included.

A one-dimensional advection model was used to simulate the movement of young (< 180 mm) anadromous least cisco (Coregonus sardinella) along the Beaufort Sea coast between the Colville River and Prudhoe Bay, Alaska. Two versions of the model simulated eastward movement during the month of July as the sum of wind-induced transport and constant dispersion. Model results were compared with fyke-net catch data collected from 1981 to 1992. Of the 12 years examined, the models correctly simulated no major arrival of fish in 1983, 1985, 1986, 1987, and 1992, simulated the exact day of arrival in 1981, 1989, and 1991, and were in error by 1 d in 1988. Approximately 71% of the error between simulated and observed arrival dates was associated with three specific years: 1982, 1984, and 1990. The model suggests that wind-governed circulation may reasonably account for the presence of young Colville River least cisco in the Prudhoe Bay area. Results are discussed in terms of their relevance for assessing the effects of Arctic oil development on regional fishery resources.

Prudhoe Bay

The Prudhoe Bay Causeway is a gravel-fill structure that extends 4 km into the Beaufort Sea at Prudhoe Bay, Alaska. Concern over the impact of this structure on the marine Arctic environment prompted regulatory agencies to require owners of the causeway to sponsor a multidisciplinary monitoring program that encompasses the physical and biological realms of possible impact. This paper describes how such concerns are being addressed and also includes results of the initial studies of possible environmental impact of the causeway.
