This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The following report presents the findings of a feasibility study, authorized by Gulf Oil Canada Limited (GOCAN) in March of 1977, to investigate the possibility of constructing an artificial island for the production of hydro-carbons in 95ft. of water in the Beaufort Sea, NWT. In order to provide a practical base for the study, the 1976 exploration drill site at Tingmiark was chosen by GOCAN as a site with environmental and soil characteristics representative of possible future hydro-carbon production sites in the general area. The project team chosen to perform the study consists of Swan Wooster Engineering Co. Ltd. (Swanco) to provide the civil engineering, Golder Brawner and Associates Ltd. (Golder Associates) to provide the geotechnical engineering, and Northern Construction Company to provide the contracting expertise and cost estimates. The scope of work involved in the study was divided into three tasks or sub-sections. Task 1, the First Stage, consisted of an initial or conceptual design stage of three Concept Islands based on design concepts proposed by Gocan, assessment of the methods of analysis and review of sources of materials and equipment. Task 2, the Second Stage, consisted of performing the analysis of wave and current scour and soil resistance to ice attack on modified versions of the Concept Islands. Task 3, or the Third Stage of the study, consisted of the finalization of the Concept Islands, a more comprehensive assessment of normal ice regime and ice rubble participation, finalization of the equipment construction schedules and cost estimates for capital and maintenance costs. ... The findings of this feasibility study indicate that Concept Island 2B (revised) would be more suitable for location in the 95ft. water depth of the Beaufort Sea than Concept Island 1 .... A feasibility study of this nature involving building an artificial island in 95ft. of water, twice the water depth attempted to date, and in the shear ice zone 50 miles offshore and beyond the present experience with island construction in the land-fast ice zone, is bound to turn up many areas requiring further study. A number of these are listed in the final Section 15 as considerations for ongoing studies"--ASTIS database.

Book excerpt: "A production facility is being considered for the extraction of oil from the Kopanoar Field in the Canadian Beaufort Sea where water depths are approximately 60 metres (200 ft). Various types of structures are being contemplated. These include primarily two different types, namely a standard artificial island with berms and caissons, and a gravity structure with berms for ice load protection. A major obstacle to the design of either type of facility is a very soft upper seabed clay stratum approximately 6 metres (20 ft) thick. This feasibility design study addresses primarily the aspects of an artificial island stability related to the foundation soil conditions. The objectives were to obtain a geotechnically sound and economically feasible conceptual design, and to evaluate other possible designs that could be constructed with equipment presently available to Dome Petroleum Ltd. in the Beaufort Sea. These objectives have been met. ... The conclusions of this feasibility study may be summarized as follows: 1. The artificial island would be unstable if founded on 6 m (20 ft) of very soft seabed clays unless it was constructed slowly over a period of many years. 2. Vertical drains used below the entire island to reduce consolidation time would be uneconomical for this project. In addition, an extended construction period would be required to allow time for sufficient strength gain in the very soft seabed clays. 3. Partial removal of the very soft seabed clays would also necessitate an extended construction period. 4. Key soils and field testing data are required to quantitatively assess the potential benefits of dynamic consolidation on stability. 5. Fill displacement methods of construction may result in sand intrusions within the very soft seabed soils or displacement of these soils. Field test data are required to evaluate this construction procedure. 6. The optimum design would involve removal of the very soft seabed clays from approximately berm crest to berm crest, beneath the island core. Additional soils data are required to determine the precise extent of removal. 7. The potential for berm toe instability is not believed to be a serious impediment to the feasibility of the artificial island, but needs further investigation. 8. The findings reported herein are based on the limited soil data currently available in the region of the proposed Kopanoar Island. When a precise location has been selected and site-specific geotechnical testing carried out, it may be possible to optimize the design of the island. The present study is based on a realistic interpretation of the regional conditions, but because of the limited data currently available it is necessarily conservative"--Executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: "In this report a computer model is presented to simulate the penetration of big, tabular icebergs (ice-islands) into artificial islands. In the model the penetration is simulated with a short time-step, including non-linear aspects such as soil-failure and ice-failure. Environmental influences like currents, wind, pack-ice, etc., are also taken into account. The model is based on the dynamic equations of conservation of momentum.... In this report the program is described in first instance as the central impact on a rectangular island. Then an identical program has been made for a circular island. For this circular island both the central and the non-central impact have been described"--Leaf [1].

Available in PDF, EPUB and Kindle. Book excerpt: Field trials carried out in Vancouver in 1986. Critical questions were the ability of hovercraft to fly over oil slicks at high speed without displacing the oil out of path, potential of hovercaraft to impart vertical mixing energy into water col umn to aid dispersion process and ability to mount suitable spray boom & obtain uniform spray pattern across swath width. Positive answers to first and last questions were obtained. There does not appear to be any significant long term vertical mixing in hovercraft wake.

This book was released on 2004 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern has been expressed by commercial fishermen that seismic surveys may affect the health and/or behaviour of snow crab. This study examines the effects of seismic survey air gun noise on snow crab & snow crab catches. The study investigated a number of health, behavioural, & reproductive variables before, during, & after seismic shooting in a preliminary attempt to assess potential effects on physical, biochemical, or activity patterns in subject crabs. The study site was Conception Bay, Newfoundland, an area considered to be typical prime crab grounds. Fishing experiments were conducted in a controlled manner using standard & modified crab traps, with seven sets prior to shooting and six afterward. Crab movement & behaviour after exposure to air gun shots was monitored for caged crabs by video camera and for transmitter-tagged crabs by hydrophones. Caged crabs were also exposed to air gun shots at various depths and were sampled to assess potential indicators of stress & physical damage, in comparison to control crabs not exposed to shots. An important component of that study was to determine if lethal effects occurred three months after exposure. Results of this research are presented & discussed and direct effects on crab physiology are summarized.

Available in PDF, EPUB and Kindle. Book excerpt: In this study, the two most recently publicly available hindcast studies for the Beaufort Sea have been reviewed. The studies, conducted respectively by Hydrotechnology and Seaconsult, differ markedly in their treatment of the storm windfields and the available fetch length. Consequently, there is a considerable disparity between their estimate of extreme wave heights for deep water conditions, although for shallow water the agreement is more favourable. A systematic assessment of their respective methodologies indicated factors which would help to undo some of the conservatism in the Seaconsult estimates and warrant a slight increase in the Hydrotechnology results.

Available in PDF, EPUB and Kindle. Book excerpt: Evaluation of the recent model developed by Wotherspoon et al. was performed by undertaking a separate spreading analysis based on the observed processes and on a review of the available literature. This evaluation was done for a spill in the southern Beaufort Sea for the case where currents are neglible. The resulting analysis was used to predict the probable spread of oil and gas under an ice sheet. The results were than compared to the predictions made by the Wotherspoon model.
