ABSTRACT This paper describes the establishment of a stable pilot-plant ecosystem and the utilization of that system in determining some of the chronic effects of oil pollution on the aquatic environment of the Gulf Coast area. Impacts on microorganisms, phytoplankton, zooplankton, marsh grass, shrimp, ...
ABSTRACT A variety of cables were studied under controlled conditions in the ocean. Sections of cable, 76.5 ft in length, were exposed to a spatially uniform, time-varying current. Vibration response, Current velocity, and tension were simultaneously recorded. Care was taken to minimize complicating ...
ABSTRACT The prospect of an ocean mining operation discharging processing wastes into the deep North Pacific Ocean raises several important environmental concerns. Mineral processing reject material frequently evokes the image of toxic metals and destroyed eco-systems, and the North Pacific is usually ...
ABSTRACT Six exploratory oil well drill sites were examined with a two-person submersible in water depths ranging from 21 to 149 m (70 to 490 ft). Time since wells were drilled ranged from 15 months to 17 years. The area of visually detectable cuttings around recently drilled wells in depths greater ...
Abstract Any mineral exploitation from sea water or from the floors of estuaries, bays, or the adjacent continental shelves will almost always involved a disturbance of the natural marine environment and an alteration of the marine ecology. Where these operations impinge upon man's other activities ...
ABSTRACT The results of a marine environmental monitoring program associated with drilling operations from a production platform near Baker Bank in the northwestern Gulf of Mexico are described. The study represents the first environmental monitoring program conducted in the Gulf of Mexico for a production ...
ABSTRACT At the moment Finland is probably the only country in the world where the industry is strongly investing in underwater technology without national programs or government support. All activity is purely commercial. The range of products - partly only developed, partly also built and delivered ...
ABSTRACT Although not easily identifiable in conventional publications, marine industries provide substantial employment opportunities. In 1980, over 2.3 million workers will be involved in marine-related employment, representing continued growth in both offshore and onshore manpower. As a result, ...
Abstract Current technology offers the operators of well-intervention equipment little opportunity to receive accurate and real-time visual feedback from the borehole when the fluid contents are opaque. As a result, the majority of operations are performed 'blind' leading to extensive use of time and ...
Abstract The United States Department of the Interior (DOI), Minerals Management Service (MMS) prepared an environmental impact statement (EIS)1 to evaluate potential environmental effects of the proposed use of floating production, storage, and offloading (FPSO) systems in the deepwater parts (i.e., ...
INTRODUCTION A new technique for the spectral energy analysis of acoustic data taken during bottom and subbottom profiling surveys will be described. This technique is intended to be an additional tool for the evaluation and analysis of subbottom data. Single frequency acoustic systems [sonars] are ...
ABSTRACT This paper describes a geophysical and geotechnical site survey for the Heritage Platform to assess jacket levelness and water depth. Data were obtained from deep-tow seismic and cone penetrometer equipment which were positioned within the survey area through the use of an on-bottom network ...
ABSTRACT Drilling mud and cuttings discharged from the more than 21,000 wells drilled offshore and in coastal waters of the United States have not caused detectable environmental damage either short-term or long-term. This is the conclusion from a study of reports of underwater observations during ...
ABSTRACT This paper discusses the development and negotiation of international standards for the removal of abandoned and disused offshore production platforms and other installations. In April 1988, after two years of intensive negotiations, the Maritime Safety Committee (MSC) of the International ...
ABSTRACT This paper discusses the systematic approach adopted by Amoco (UK) Exploration Co. Ltd. (AMOEX) in order to achieve its project objectives during a recent platform well abandonment campaign. An integrated team, comprised of key service company personnel working in conjunction with the oil ...
Abstract Every human activity in the offshore Arctic, or anywhere offshore for that matter, emits some level of sound into the marine environment. Depending on intensity, and to some extent frequency, underwater sound can be a nuisance or even physically harmful to marine life. The indigenous people ...
Abstract This paper describes how Memorial University is using a new ocean going autonomous underwater vehicle (AUV) to collect ocean environmental monitoring data to take detailed environmental measurements in the water column and to validate ocean environmental monitoring and modeling tools. The research ...
ABSTRACT As a result of the Santa Barbara Channel oil pollution incident in early 1969, various California State agencies undertook a thorough joint study of state regulations and inspection practices. Recommendations were made to assure that public safety, property and environmental quality received ...
ABSTRACT Paper describes the geological setting in the Arabian Sea For a proposed 28-inch gas pipeline from Oman to India Reaching 3,500-m water depths. Covers planning, Execution, quality control and results of geophysical, Geotechnical and oceanographic surveys. Outlines theory And application of ...
ABSTRACT Atlantic Richfield's concern for environmental protection has led to participation in several interesting ecological experiments. Space, along with engineering and operational assistance, is currently provided on its offshore Texas platforms in the High Island Block 24-L Field for three experiments ...
