INTRODUCTION Oil and gas exploration and development in the western Arctic now spreads from the center of the Chukchi Sea to east of the Makenzie River in Canada offshore, and is centered around Prudhoe Bay in Alaska and the Makenzie Delta in Canada onshore. Earlier explorations in the 1940s and 1950s ...
ABSTRACT: The Continuous Line Bucket (CLB) is a mechanical system using an endless loop of rope suspended from ''a surface platform to reach the seabed and to which dredge buckets are attached at regular intervals. The Turning CLB is a recent important innovation; by steering the vessel in a circular ...
ABSTRACT The importance of natural gas in the European Countries has grown significantly since the first years of Millennium 2000. The increasing popularity of this fuel source is mainly related to relevant low emissions to the environment and its flexibility in energy production. In order to meet ...
ABSTRACT: The subsea tieback routes of the Medway Field Development cross a mobile seabed with large sand waves and numerous megaripples. To allow the pipelines to be laid, without excessive free spanning, two lay corridors were pre-swept using a Trailing Suction Hopper Dredger (TSHD). The requirement ...
The Arctic energy in Russian Federation is developing in two directions. Building up the means of ""big"" and ""small"" energy. The main sources for ""big"" energy complexes, serving the needs of large industrial centres, are hydroelectric power, hydrocarbon stuff and nuclear power. The principal task ...
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 the Cook Islands, or similar deposits, at 5,000 m depths at a rate of 1,000 tons/day, is estimated to be US$69, which is favorably ...
Introduction The PCR-based analysis of homologous genes has become one of the most powerful approaches for species detection and identification, particularly with the recent availability of Next Generation Sequencing platforms (NGS) making it possible to identify species composition from a broad range ...
Summary Identifying and locating active faults in coastal and offshore areas require high-resolution geophysical methods where trenching is impossible at subaqueous sites. Multi-channelseismic reflection profiling using high-frequency (100-10,000 Hz) energy sources and state-of-the-art digital streamers ...
ABSTRACT Currently, in Europe approximately 20% of its electricity comes from renewable energy sources. Regarding wind energy, as most of the inland prime locations are being used up, the next place to look for wind is offshore. In addition, one of the most promising renewable energy sources is sea ...
Abstract: This paper outlines the potential for electricity production from the rapid tidal currents experienced in the waters around Orkney and Shetland, which lie off the north coast of the mainland of Scotland. The potential resource availability is examined, taking into account the limitations ...
ABSTRACT: There is evidence of changes in sea level and wave height on various time-scales, globally and regionally. For example, the North Atlantic Oscillation appears to be correlated with increasing wave height in the North Atlantic over recent decades. These changes may or may not be anthropogenic ...
ABSTRACT: The clean-up of oil spills in the Arctic environment is often limited by severe and cold environmental conditions. Mechanical methods are usually considered to be most favourable for oil spill combatting. However, remote spin sites, long distances, severe environmental conditions and sensitive ...
ABSTRACT The extreme shallow water area of Zhangjuhe is a portion of the complex-forms oil-gas rich area in the rifted basin of Bohai Bay. The Zhangxi Structure in this area is a rollover anticline and the Zhangdong Structure is a large-scale faulted anticline zone controlled by the basement swell. ...
ABSTRACT Large arrays of interconnected pontoons have been developed in the past for structures such as bridges when connected in a line, and are also being considered for a range of projects such as floating harbours, and even airports when these arrays are extended to mat-like structures. The benefits ...
ABSTRACT This study analyzes and synthesizes the sea water overflow (overtopping) patterns caused by typhoon Maemi in September, 2003, and movement mechanism of storm surge and high wave connected directly to inundation are investigated by topographical characteristics of open-end and closed coastal ...
ABSTRACT The land reclamation area of Saemangeum in Korea is located between 126°10′E～126°50′E and 35°35′N～36°05′N at the western coast of the Korea. The 33 km sea dike and 40,100 ha reclamation area is being constructed in the Saemangeum area in Korea. Such large-scale coastal land reclamation project ...
ABSTRACT: Environmental measurement of Dokai Bay surrounded by a Japanese leading heavy and chemical industrial area is evaluated as one of the success instances from the heavy industrial pollution which degraded the bay’s ecosystem to be called “the dead sea”. After the restoration, the bay newly ...
ABSTRACT Trawling is one of the methods of fishing. In this paper, single boat trawling is taken up and the method to calculate the motion of a trawl net system using the lumped mass method is shown. In calculation, rational simplification of the trawl net system (creation of an approximation model) ...
A new type of floating breakwater, mainly using the wave dissipation mechanism caused by wave slamming to a bundle of cylindrical members near the water surface, was developed. It aims attenuation of both reflected and transmitted waves about the floating breakwater. Model tests show that the basic ...
ABSTRACT Wave power density near Japan is hot so high as Europe where wave power is under developing by Joule II project. But multi purpose wave power generator can be designed to generate electricity and promote fishing business near shore. It is improved floating type wave power device. CylInder ...
