There are numerous unresolved international legal problems which may affect the exploitation and investigation of the ocean. Most of the uncertainties probably will not be resolved for several years. There will be increasing international discussion and negotiation regarding the law of the sea in the ...
ABSTRACT The design and construction planning of deepwater tunneled ocean outfalls involves both underground and offshore engineering. In particular, the demands placed on the outfall seabed riser structures requires consideration of many of the engineering disciplines associated with the offshore industry. ...
ABSTRACT This paper summarizes the data obtained from site surveying and sediment sampling of dredge spoil disposal mounds at the Central Long Island Sound site. Emphasis is placed on the geotechnical and geological features of the mound natural seabed. Since some of the spoil is contaminated, cappings ...
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 This paper ...
ABSTRACT Optical viewing systems are severely hampered in muddy water. Under these circumstances, increased viewing distance (but less resolution) can be expected from ""viewing"" systems using longer wavelength acoustical energy. Acoustic images approaching optical quality can be obtained at short ...
Abstract A new drill pipe size, 5-7/8 in. OD, represents enabling technology for Extended Reach Drilling (ERD), deepwater and other deep well applications. Most world-class ERD and deepwater wells have traditionally been drilled with 5-1/2 in. drill pipe or a combination of 6-5/8 in. and 5-1/2 in. drill ...
ABSTRACT The Buccaneer oil/gas field, offshore Galveston, Texas, has been in operation for some 15 years and thus provides a good example of the effects of offshore exploration and production on the marine environment. As sediments are the ultimate sink for contaminants in the marine environment, a ...
ABSTRACT The cooling water system for the Seabrook Nuclear Power Station represents a unique venture in the utilization of the Ocean as a source for the plant's cooling water. An extensive tunnel system, bored out in bedrock, well under the waters surface will be used to connect the land based plant ...
INTRODUCTION The ESARC is a multipurpose geological and geophysical survey ship for deep waters and rough sea conditions, the main feature of which is the use of flexodrilling. The USSR has ordered one of these vessels from SERETE, a French engineering company. The tasks that can be performed by this ...
Abstract Kikeh is Malaysia's first offshore deepwater development. Located in the South China Sea offshore the east Malaysian state of Sabah, the Kikeh oilfield lies in average water depths of 1,320 meters. With recoverable reserves in excess of 400 million barrels of oil, it is expected to achieve ...
Abstract This paper describes the major issues which have been addressed in the conceptual phase of the project in order to manage the project in a controlled manner. These issues are. Establishment of a philosophy and strategy for the Cessation Process. Clear definition of the Cessation Phases, ...
Abstract Export and import offshore LNG terminals have a bright future… and the technology is here. As part of the most visible benefits are stranded gas monetization, no land availability issues, reduced administrative pressure, and distance from politically unstable regions. The Floating LNG industry ...
ABSTRACT Evaluation of dynamic positioning systems consists principally of determining the holding capability against expected weather and the reliability of the DP system in operation. Efforts to quantify reliability, by estimating mean time between failure, now permit several useful risk analysis ...
ABSTRACT Offshore pressure maintenance programs involve handling large quantities of seawater in predominantly carbon steel systems. Problems such as effect of the seawater on the formation, corrosion and deterioration of materials of construction caused by seawater, scaling, oxygen corrosion, and ...
ABSTRACT Echo sounding, side scan sonar and seismic profile records in the Canadian Beaufort Sea provide evidence of trenches or ""scours"" on the continental shelf sea bottom. These are generally believed to be caused due to grounding of ice masses. Records obtained over a three year period by government ...
ABSTRACT A number of geophysical methods and survey devices are available for conducting comprehensive studies of submarine pipeline routes. The primary objectives of these studies are to determine water depths, sediment characteristics, depth or presence of bedrock, bottom debris, existing currents ...
Abstract The continuous line bucket (CLB) system has been improved by combining the techniques-of the Turning CLB and Hydrodynamic Separation. The cost of mining nodules from 5,000 m water depth at a rate of 1,000 tons/day is estimated to be $77, which is favorably competitive with the cost of mining ...
ABSTRACT Sidecast dredging has been employed annually in the New England region for the past four years. Operation of the dredge is restricted to inlet channels and ocean sand shoals. Physical and chemical analysis of sediment samples from eighteen navigation projects confirm that the dredged material ...
ABSTRACT Important quantities of sand and gravel lay on the French continental shelf, particularly in the Channel and on the Atlantic coast. The extracting activities have been increasing in the last ten years. However, only very small companies using rather small dredges carry on their activities. Mining ...
ABSTRACT The MONOPILE is a new concept of single point mooring/loading system developed for application in 350 mw.d. in the Northern North Sea by Tecnomare and Aker Engineering as a result of a joint research project funded by Norsk Agip. The concept consists? of a slender column extending from the ...
