Metocean, ICe and Seismic Conditions Offshore Notheastern Sakhalin Island

摘要

Some 40 years of hydrocarbon development in arctic and subarctic regions of the continental shelf have given the industry extensive knowledge and experience in the effective design of offshore infrastructure. Major environmental conditions impacting and ice conditions. The Sakhalin 2 team analyzed these dynamics-and their interaction with an ice cover system-within the context of the region's specific geographic characteristics to achieve an optimum cost-effective design concept for the Piltun-Stokhskove and Lunskoye fields. Futhrer, the project tema set out to design fit-for purpose facilities capable of withstanding the challenges of the environment. A key point here is the avoidance of overdesign. The methodological approach called for the planning and development of these oil and gas resources based on a phase field development. The Sakhalin 2 team also agree that its initial environmental data-including the dynamics-would drive the design definition process. Sakhalin Energy began studying the environmental conditions of the Piltun-Astokhskoye and Lunskoye fields in 1991. The team broadened the sonpe of the study in 1995 to incorporate the contributions of several Russian organizations. These extensive studies helped to define the cost of the project and helped to set economic parameters for future arctic developments.
