ABSTRACT Shell dredging in estuarine areas started with the arrival of early settlers. Although modern techniques decreased the number of dredges, the output has increased considerably. In order to dredge, a dredging company must receive a permit from the proper state agency to remove such state-owned ...
1.0 Abstract The selection of candidate deepwater petroleum terminal sites from an area hounded by Boston Harbor on the south and the New Hampshire border on the north was the object of this investigation. Four zones in the study area were defined, and one site in each area was selected for environmental ...
ABSTRACT A concept for a national program for oceanic monitoring, assessment, and prediction (OMAP) is described. Initial emphasis is placed on services to support the marine leg of the Trans-Alaska Pipeline system (TAPS) in the form of warnings of hazardous phenomena, forecasts of marine weather and ...
Abstract The Oooguruk project is located in the Alaskan Beaufort Sea and consists of a 6 acre gravel drill site approximately 5 miles offshore in 4.5 feet of water. The drill site is connected to an onshore facility by a complex flowline system consisting of a 5.7 mile subsea buried flowline bundle ...
ABSTRACT Hazard surveys have been completed for exploration drilling on the U.S. Atlantic continental slope to water depths of 2000 m. Two regional surveys, near Carteret Canyon and south of Georges Bank, provided a geologic basis for 10 subsequent site-specific studies. Regional data were gathered ...
Abstract The Penguins Field is located in the most northern waters of the United Kingdom Sector of the North Sea, approx. 250km NE of the Shetland Isles, Scotland. The pipeline comprises 66km of Pipe-in-Pipe (PIP) in water depths peaking at 170m. The HT/HP pipeline navigates a sinuous route through ...
1.Abstract The purpose of this paper is to report on coring operations carried out by International Hydrodynamics in the Hudson Bay during the summer of 1971. During these operations core samples were taken on a number of locations using a surface delivered and operated coring device and a submersible ...
ABSTRACT This paper discusses the planning of harbor dredging when mercury-contaminated sediments are found. The major considerations, in addition to those normally considered, are the extent of mercury contamination and the problem of how to safely dispose of the material on land. It is shown that ...
ABSTRACT Fish protein concentrates (FPC's) have been used in various parts of the world for several centuries. It has only been within the past 30 years, however, that the production of FPC has been investigated on a scientific basis. Today several pilot plants and full scale industrial plants have ...
Abstract Based on the detailed study of 600 grab samples and cores collected in Green Bay, an arm of Lake Michigan, the presence of a major underwater mineral resource of manganese has been established. The manganese occurs combined with iron in pellets, the majority of which range in size from 0.1 ...
ABSTRACT This paper describes a downhole retrievable hydraulic force generator for coiled tubing. The purpose of this system is to hydraulically generate downhole push and pull forces, thereby eliminating the need to stretch and compress the string of coiled tubing to accomplish mechanical work downhole. ...
Due to a paper numbering error, this number was previously assigned to apaper presented at the 1975 Offshore Technology Conference. Todistinguish between the two papers, the filename extension -A has been added tothe 1975 paper and the filename extension -B has been added to this paper. ABSTRACT The ...
Abstract Continental margins of Canada represent vast potential for storing hydrocarbon gas (largely methane) in the form of gas hydrate. The theoretical stability field for gas hydrate encompasses some 120,000 km2 along the Scotian margin. Examination of >34,000 line-km of industry 2D seismic reflection ...
Abstract The wireline Well Tractor has in the North Sea area completed various wireline jobs in horizontal and extended reach deviated wells. The electric driven Well Tractor has made it possible to perform wireline operations in horizontal and deviated wells such as PLT jobs with surface read out, ...
ABSTRACT This paper describes the successful drilling of exploration wells from a dynamically stationed drill ship in water depths ranging between 1, 000 and 2,200 feet. The operating performance of the subsea and stationing equipment is reported.Specifically outlined is the operational experience ...
ABSTRACT It is known that some Single Point Mooring hawsers have failed at sea after being subjected to tensile loadings never higher Than half their original breaking load. Previous work has shown relationships between rope fatigue life and maximum cyclic load in tension in the form of Sc-Nf curves ...
ABSTRACT This paper reviews the status of mining offshore for sand and gravel on a world-wide basis. It discusses the technology for exploration and evaluation of sea floor mineral targets, as well as mining, transportation, and processing. Large operations in Japan and Europe are described, based ...
ABSTRACT Ten years after the installation of the Beryl platform, severe corrosion to several sea water lift pump caissons necessitated structural repairs. The repairs to the caissons were effected underwater using structural clamps to provide a structural load path and to seal large holes in the caissons. The ...
ABSTRACT Shell Offshore Inc. (SOI) as operator, with Joint Venture participation of Amoco Production Company and Sun Exploration and Production Company, spudded the first of several planned East Coast deepwater wells in a world record 6,448' of water during August 1983. The well, in Wilmington Canyon ...
ABSTRACT A feasibility study is summarized which analyzed and compared two diverse configurations being considered for a mast which will provide a stable platform for engineering and scientific measurements in a unique deep ocean environment associated with a seamount in the Pacific Ocean. The representative ...
