Book excerpt: "Between Dome Petroleum Company of Calgary - Alberta, Canada, and Nedeco of The Hague, Holland, an agreement has been concluded for technical assistance in the study of the possibilities of an artificial island in the Beaufort Sea for oil exploitation. In this framework an order for a partial study was granted to Rijkswaterstaat in order to determine the slopes which can be realized in the construction of such an island. This study has been carried out in close cooperation with the Delft Soil Mechanics Laboratory. ... The question, if a slope of 1 : 5 could be realized, has been added to this problem definition. The aim of the study was to determine how, as a function of equipment execution methods, borrow material properties and observing the physical boundary conditions c.q. circumstances, an as steep as possible slope could be realized, with sand and construction material. In the study other construction methods, should not be envisaged at this stage. The study, which has the character of a prefeasibility study, should be carried out as a desk study in which the different determining parameters should be varied as much as possible.

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.

This book was released on 1980 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Within the framework of the technical assistance to Dome Petroleum Company Canada, a study has been executed by Nedeco, (The Netherlands), on the possible erosion control systems for the top of a test island to be realized in the Beaufort Sea. The definition of the problem, as formulated by Dome, is detailed in Appendix 1. By special request, the realization of a system consisting of fixed ballast mats has been considered. The nature of the problems and the special circumstances in the Beaufort Sea require a complete study of a very large number of alternatives. Considering the very short time available for the investigation, the number of alternatives has been limited to those which are known to be realistic from existing prototype or scale execution methods. The working circumstances in the Beaufort Sea were also taken into consideration in the evaluation of the available methods. The presentation of the methods, and particularly the conclusions, apply to the test island. In case application for an APLA should also be considered, it is possible that the conclusions will have to be adjusted in view of the changing efficiency of investments in equipment. The present study contains particularly the primary calculations, considerations and conclusions."--Page 1.

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].

This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Dome Petroleum Ltd. is planning to construct the first of their artificial islands in the Beaufort Sea sometime during the late summer or early fall of this year. The proposed island will be located offshore in a water depth of 23m and consists of four self contained caissons placed on a dredged soil berm. The intended use of the island is twofold, namely, to use it as a platform for explorational drilling as well as to employ it as a full scale experimental structure which offers the unique opportunity to measure undistorted ice forces and ice pressures. Data gathered from this structure can then be utilized to establish design criteria for the construction of future islands located in greater water depths. The work outlined in this proposal relates mainly to the experimental nature of this island. So called false front pressure panels which are made out of steel and/or concrete are attached to the front face of the caisson(s) as shown in Figure 1. The configuration of a typical panel consists of a structurally sound plate and beam structure which transmits ice loads via load cells or flat jacks to the caisson. Overall average normal and/or shear loads are measured by the cells or jacks whereas localized stress concentrations are measured by employing sensing devices which are either built into the panel or are directly attached to the panel surface. The panels have to be anchored to the caisson. The anchor points have to be designed with great care in order to ensure that all possible loads are being properly transferred" -- ASTIS [online] database.
