Offshore (Subsea) Power Delivery Management Model

摘要

Offshore (subsea) power delivery systems have traditionally been viewed as a second order decision for upstream energy projects. The primary focus has been the hydrocarbon value chain, or the physical path of bringing oil or gas to market: reservoir fluid flow through the well completions and subsea facilities to the offshore process host, and finally to export pipelines. Moreover, although proven and in wide use for the hydrocarbon value chain, the traditional decision-making modeling process is yet to be applied for the offshore (subsea) power delivery because of its perceived insignificance. However, the pending difficulty in developing long-offset and/or marginal lease areas (oil or gas), the volatile commodity market, and climate change regulations uncertainty dictate that an alternative view where power is no longer a second-order decision will be needed.rnThis paper describes an IT-enabled power delivery management (PDM) model to address the many challenges inherent in decision-making for offshore (subsea) power delivery. These challenges include the diversity in functional disciplines required for effective decision-making, many dimensions of potential value and system design trade-offs (e.g. local power vs. power-from-shore), varying perceptions of value by stakeholders, the need to accommodate uncertainty, and the need to align actions of individuals to higher-level corporate objectives.rnThe PDM model is supported by an integrated decision environment where the stakeholders, operators, systems integrators, and suppliers, can interact seamlessly. This novel approach will aid in the increased uptake of new technologies for offshore (subsea) power delivery. In addition, it can eliminate knowledge islands and re-work errors (i.e. data is entered once and used many times); it simplifies complex decisions making cross-discipline impacts explicit; it standardizes the system decision model and reporting format; and automates the decision models so it can be re-used and tailored in repeatable ways by the team or other stakeholders.
