CHARACTERISTICS OF DEEP-SEA ANCHOR CABLES IN STRONG OCEAN CURRENTS

Abstract

This analysis examines the steady state configuration of a deep-sea mooring cable in realistic ocean currents in a nominal water depth of 12,000 ft. The earlier solutions of the problem of a cable in a uniform current are adapted to variable distributions of velocity by the artifice of considering the ocean as a series of laminae within each of which the current can be regarded as uniform. The calculation procedure is developed for stepwise numerical integrations, and computations were made for a wide range of sizes of steel-wire and nylon rope mooring lines under two conditions of severe ocean currents, involving 6 and 3 knot velocities at the surface. Influences of the current are taken to vanish at a depth below the surface of 1000 m (3280 ft). Justifications for the choice of design currents are given. Results of the calculations are available in a series of figures and tables. Several examples of the use of the tables are given in solution of mooring problems.
