Showing papers in "Ocean Engineering in 1977"

TL;DR: A review of cylinders in steady currents can be found in this paper, where the effects of length/diameter ratio, cylinder surface roughness and channel blockage are discussed, and the results of tests with pane and three-dimensional frames are described and quantified in terms of isolated cylinder data.

TL;DR: In this paper, a self-contained, discus-hulled buoy 1.5 m dia, weighing 150 kg, which uses inertial instruments to measure wave height and tilt is described.

TL;DR: In this article, the authors describe the development and application of a system for quantitative near-bottom seismic profiling at 4 kHz, which was developed as part of the Deep Tow Instrumentation System of the Marine Physical Laboratory.

TL;DR: In this paper, the authors applied the computerized model on surface wave refraction by Wilson (1966) to the topographic data of the southern North Sea and found that there is an agreement between these refraction coefficients and the coefficients calculated from wave data obtained at various stations in the same area.

TL;DR: In this paper, a dual-mode release has been used on untethered, mid-water vehicles successfully since 1970, which is operated by electrical signal or by hydrostatic pressure.

TL;DR: In this article, the relationship between the depth and trail attained by a towed submerged vehicle and the magnitude and direction of the forces on it has been examined theoretically, for cases involving faired cables.

TL;DR: In this paper, various aspects of studies on the motions of ocean platforms are reviewed, with emphasis on floating and semi-submerged structures, and motion correlations are made with full scale observations.

TL;DR: In this article, the authors examined the dynamic response of shallow, nearly horizontal, towing cables to periodic horizontal end displacements using the assumption that the shape of the dynamic deflections is of the same general form as the equilibrium shape.

TL;DR: In this paper, the optimum performance of a simple Rankine cycle ocean thermal energy conversion plant is investigated analytically, and it is shown that the ratio of maximum net power output to heat exchanger surface area varies as H(Δt − t 0 ) 2 where H describes the overall heat transfer properties of the evaporator and condenser, and t 0 is a parameter depending primarily upon the pressure drops across the warm and cold sea water pumping systems.

TL;DR: A spill of #2 fuel oil occurred 28 January 1977 in a dynamic ice field in BBuzzards Bay, Massachusetts as discussed by the authors, where the movement of the oil (initially spilled under the ice) into the fracture zones appears to be the result of water current below the ice and buoyancy spreading mechanisms.

TL;DR: In this article, the authors measured the torque required to actuate the emergency forebody release device of the research submersible Alvin and determined the coefficient of static friction for the contacting metals, Monel K-500 and phosphor bronze A. Coefficient values fell in the range 0.12-0.24.

TL;DR: In this paper, the effects of the weight distribution on the roll motion of an LNG carrier based upon model tests results were discussed, which consisted of extinction tests in calm water as well as roll response tests in regular beam waves.

TL;DR: In this article, a minor generalization of the theory of random walk is used as a basis for a model of ocean current flow, which is then applied in a computer simulation of drifter motion.
