ABSTRACT There is a need to continue geophysical research for petroleum exploration and exploitation, and for basic understanding of marine geology, and for assessment of energy and minerals resources. There is also a need to conduct that research compatibly with our marine environment. Modern marine ...
ABSTRACT This paper presents a review in narrative form of the various main elements of submarine telephone cable repair work at sea. Generally well known techniques are mentioned only in passing; specific techniques peculiar to cable work are described more fully, but with no mathematical treatment. ...
Abstract Industrial class vessels (offshore supply boats, tugs, and fishing vessels) have experienced stability problems during the last two decades. Many of these vessels are of similar hull form, including hard chins, a shallow-depth transom stern and large beam/length ratios. Existing stability criteria ...
Abstract In the Gulf of Mexico, the distinction between natural and artificial resources has become obscure. Over one quarter of the hard substrate existing offshore has been created by the steel legs of nearly 4,000 petroleum platforms. The encrusting organisms and reef fish communities established ...
ABSTRACT Fish protein concentrates (FPC's) may be defined as those products obtained from fish in which the protein is more concentrated than in the original raw material. FPC's may range from light-colored, bland powders to dark powders having intensely fishy tastes, or they may be pastes with a similar ...
ABSTRACT The paper compares the organization of the federal-industry relationship of a number of countries. This comparison is made against a hypothetical idealized nation which is organized to develop ocean resources in the best national interest. The paper demonstrates that of the nations examined, ...
Due to a paper numbering error, this number was also assigned to a paperpresented at the 1976 Offshore Technology Conference. To distinguishbetween the two papers, the filename extension -B has been added to the 1976paper and the filename extension -A has been added to this paper. ABSTRACT The accurate ...
ABSTRACT Submarine cables and pipelines placed on the ocean floor must operate reliably for periods of up to 30 years. To ensure such reliability, cables and pipelines must be protected against both natural phenomena as well as human activity. As part of the Department of Energy Ocean Thermal Energy ...
ABSTRACT Southwest Research Institute is presently managing a relatively large program in offshore ecology for the Bureau of Land Management (BLM), Department of the Interior. The study involves university and private subcontractors representing several scientific disciplines. Project objectives .are ...
Abstract The oil industry is spending millions of dollars annually to develop and utilize improved technology to maximize safety and protect the environment in offshore operations. Considerable publicity has been given to these efforts in the areas of petroleum production and transportation. Environmental ...
ABSTRACT This paper is concerned with the recent development of a technique to simultaneously lay and bury flexible pipelines and control lines. The development of this technique using a fully dynamically positioned laying vessel is followed through from concept to pre-operational trials and finally ...
ABSTRACT This paper provides a brief historic look at downhole video in the petroleum industry, including early tool designs, configurations, and uses. Evolving technological improvements are addressed, including fiber optic telemetry. Advantages of recent innovations are covered. A review of the varied ...
ABSTRACT The results of a multi-million dollar environmental research program consisting of thirty-three wildlife, biological, oceanographic meteorological, sea ice, and oil clean-up studies related to the southern Beaufort Sea are presented. The studies were designed to provide ecological baselines, ...
ABSTRACT Biological and water quality changes in the Gulf of Mexico off the central Louisiana coast have been examined during a seasonal period of stratification and oxygen depletion in the water column. Probable causes, observed effects, and potential impacts on the timing of ocean discharges and ...
ABSTRACT A deeply towed system for fine scale deep ocean surveys has been assembled by the Marine Physical Laboratory over the last 15 years. It consists of precision echo sounder, sub-bottom penetration sounder, side-looking sonar, cameras, TV, magnetometer and a variety of other specialized measurement ...
Abstract Introduction With the shortage of 2D and 3D seismic vessels, rather than build a new vessel some companies are converting suitable candidate vessels into seismic vessels. Building new vessels is expensive and presents difficulty in finding a yard with vacant spots for the build and the necessary ...
ABSTRACT The fate of drill cuttings from offshore wells, and their effect on the marine environment, have been studied by means of sidescan sonar, scuba and underwater photography. Adverse effects are minimal and short-lived, and in some instances the accumulation of cuttings may be beneficial. Modification ...
ABSTRACT This paper describes a new parallel wire cable named ""New-PPWS,"" developed for deepwater mooring lines. New-PPWS has a slightly twisted parallel wire construction with double-layered polyethylene and laminated lead tape for water tightness. To confirm the reliability of the cable in seawater ...
Abstract During December 2003 - January 2004 a sea bed logging acquisition was conducted across the North Sea Troll Field. Different EM wave forms and frequencies were tested to optimize the hydrocarbon response from this shallow water gas and oil field. The survey consists of 41 receivers, deployed ...
ABSTRACT It is now essential to survey the sea-bed in great detail, to gather precise information at an exact location in order to minimize damage to large structures when working in great water depths. The only sure way to achieve this at present is with a manned submersible, but the next major advance ...
