Optimised operation of low-emission offshore oil and gas platform integrated energy systems

Abstract

This paper considers the operation of offshore oil and gas platform energy systems with energy supply from wind turbines to reduce local CO 2 emissions.A new integrated energy system model for operational planning and simulation has been developed and implemented in an open-source software tool (Oogeso). This model and tool is first presented, and then applied on a relevant North Sea case with different energy supply alternatives to quantify and compare emission reductions and other key indicators.

Modelling and analysis of offshore energy hubs

“…The power consumption of a pump is given by 𝜅 𝑃 𝑢 𝑝 𝑉 𝑃 𝑢 𝑝𝑡 , where 𝑉 𝑃 𝑢 𝑝𝑡 is the fluid pumped by a pump, 𝜅 𝑃 𝑢 𝑝 is the electricity demand as fraction of amount of fluid pumped. The detailed derivation of power consumption of compressors and pumps is presented in [83].…”

Dynamic Process Modeling of Topside Systems for Evaluating Power Consumption and Possibilities of Using Wind Power

“…Offshore oil and gas platforms are usually isolated systems consisting of many energyconsuming units with local power supplied by gas turbines that use natural gas or diesel [1]. Gas turbines can also be used to directly drive compressors and pumps.…”

“…The majority of the new methods are prohibitively expensive, have stability issues, require a considerable amount of grid transmission capacity, or are not yet available. Thus, a new operational strategy is needed to best use the available resources within the constraints of new energy supply options [1].…”

“…The technology is already commercially available, and the oil and gas industry has expressed interest in developing offshore wind power installations [9]. The integration of an offshore wind farm is comparable in terms of weight and space requirements to other alternatives for reducing emissions from offshore platforms [1], and an important part of the global energy transition is the usage of floating offshore wind farms. However, neither an offshore greenfield development project nor an operating brownfield project has yet included floating wind electrification in their development and design [10].…”

“…This study was primarily concerned with the mixing of hydrogen with natural gas at an onshore gas gate station. Svendsen [1] developed a new integrated energy system model for operational planning and simulation to reduce local CO 2 emissions. An energy consumption mathematical model was proposed, as well as some factors that can affect the performance of an energy system were studied.…”
