ABSTRACT The Minerals Management Service (MMS) published new proposed decommissioning regulations on July 7, 2000. The regulations include alternative platform removal depths, improved well plugging and site clearance procedures, and a statement supporting alternative uses for decommissioned facilities. ...
ABSTRACT The development of wave energy conversion has reached the pre-commercialization stage; with many developers ready for full-scale grid-connected deployment. In many cases developers are required to produce an Environmental Impact Assessment (EIA) to be granted permission for development of ...
ABSTRACT The aim of this paper is to present the results of the comparison of several methods that have been tested for measuring fish body lengths. After a brief overview of imaging quantitative optical imaging methods, the three selected methods are described. The first method uses a laser scale, ...
ABSTRACT A measurement while drilling tool is described which is designed to provide neutron porosity and density logs of excellent quality. This recently developed nuclear logging tool for Logging While Drilling (LWD) is called the Compensated Density Neutron (CDN* ) tool since it combines two important ...
Summary Early in 2005 the US research vessel R/V Maurice Ewing, operated by Lamont-Doherty Earth Observatory at Columbia University, conducted an academic seismic survey of the Chicxulub impact crater in the shallow water offshore Yucatan, Mexico. This survey was the focus of a campaign by environmental ...
ABSTRACT The shortage of metals around the world has brought about renewed interest in the development of seafloor massive sulfide (SMS). There being no precedent for SMS development, then a lot of problems are concerned about. Among them, these are problems that must be overcome for successful development, ...
An analysis methodology is proposed according to the guidelines for Formal Safety Assessment approved by IMO. Variation Tree Analysis, Database Analysis and Event Tree Analysis are applied to the marine casualty data on collision accidents involving fishing vessels and cargo vessels. Trial calculations ...
ABSTRACT Chevron Platforms Hazel, Hilda, Hope and Heidi (known as 4-H Platforms) located in the California State waters offshore Santa Barbara Channel were decommissioned and removed from the ocean floor under a single dismantling and removal contract during the spring and summer of 1996. A unique ...
ABSTRACT: A new type of steel floating breakwater, which is comprised of a boxtype pontoon and truss structure, was designed for incident waves to be broken efficiently by the front truss and for the pontoon to suppress the transmission of the small broken waves. The performance of wave absorption ...
ABSTRACT: A trial project for the improvement of seawater quality has been carried out in the New Nagasaki Fishery Port since the end of May 2001. 60 units of 3-dimensional asymmetrical bottom roughness with directional resistance properties were installed in order to enhance tidal residual currents ...
ABSTRACT The study presented here describes the geometry optimization of the Sea wave Slot cone Generator (SSG) overtopping wave energy converter as part of the feasibility study for the implementation of the device in the development plan of Hanstholm harbour in Denmark. The total length of the new ...
ABSTRACT: In this study the authors are looking at the environmental risks of oil transport activity in the Russian Federation’s Far East offshore regions. The ecological risks which emerge during the functioning of the pipeline system and oil trans-shipping terminal are presented. A modeling of oil ...
ABSTRACT: On-site weather data were collected for Otsu Fishing Port in Hokkaido in the winter of 2003 to 2004, where freezing in winter causes significant economic damage, and the heat budget properties of the port were clarified. The net long-wave radiation was the highest in total heat loss at over ...
ABSTRACT For a typical field development project within the Northern Norwegian Continental Shelf, facing the North Atlantic and Barents Seas, some particular challenges are faced. These relate to the very irregular and partly soft seabed creating free spans, with trawl interaction, and maintenance ...
ABSTRACT: The results of ecological surveys performed in the summer of 2003 in the Aniva Bay and on the shelf of north-eastern Sakhalin are presented. On the basis of an extensive experimental material and its statistical processing the conclusion about the effect of the sea petroleum-gas complex on ...
ABSTRACT: TAKUMI the prototype of Ocean Nutrient Enhancer, which upwells and discharges Deep Ocean Water (DOW) in the euphotic layer and increases a primary production in the sea, was set up in Sagami bay in May 2003. Since then, TAKUMI has been continuously upwelling the DOW of 100,000m3/day from ...
ABSTRACT: The underwater sea-mountain using large amount of coal-ash-concrete has been constructed in coastal area of about 100m depths to enhance primary productivity due to upwelled mixing of bottom water containing more nutrients into the euphotic layer by harnessing tidal current. The man-made ...
ABSTRACT Korea has developed a number of fishing ports, including 105 national and 319 regional fishing ports, for about 30 years since national and regional ports were specified in 1971 at first. Recently fishing port facilities with a function of tourism in their waterfront area are insufficient ...
ABSTRACT: In this paper, we propose the Deep Ocean Water (DOW) Upwelling Machine which is driven by the Ocean Thermal Energy Conversion (OTEC) for the purpose to increase the primary production in the stratified sea area of low latitude, so called “the sea of desert”. In the area, there are very little ...
ABSTRACT: Rhode Island’s Coastal Resources Management Council (CRMC) has been leading an Ocean Special Area Management Plan (SAMP) resulting in zoning of the state’s coastal water to accommodate offshore wind farms. The wind farm siting issue has been previously considered as an optimization problem ...
