Abstract

In this work we couple experimental and modelling outputs to explore the potential for new technologies to reduce the costs associated with hydrate prevention in subsea field developments. Previous experimental outcomes are combined with OLGA® simulations using both the UWA Gas Dominant Hydrate Extension and Colorado School of Mines’ CSMHyK module. We find that employing a combination of technologies including novel subsea separation, thermoplastic composite materials and environmentally friendly surfactants may enable the removal of MEG injection and recovery facilities. The use of such predictive tools thereby represents an opportunity to simultaneously de-risk and decarbonise new offshore developments.
