Effect of drill string lateral vibrations on wellbore stability and optimal mud pressure determination
(Journal article; Peer reviewed, 2025)Wellbore instability is a critical issue in drilling operations, contributing to significant non-productive time and costly delays. While previous studies have focused on physicochemical and mechanical causes of wellbore ... -
Multi-stage monitoring of hydrogen systems for improved maintenance approaches: an extensive review
(Journal article; Peer reviewed, 2025)Hydrogen is considered a promising solution for global decarbonisation as an alternative to fossil fuels. However, it can interact with and brittle most metallic materials and is highly flammable. These properties call for ... -
Putting the costs and benefits of carbon capture and storage into perspective: a multi-sector to multi-product analysis
(Journal article; Peer reviewed, 2024)Carbon dioxide capture, transport, and storage (CCS) is essential in achieving the net-zero target. Despite this increasing recognition, current CCS deployments are far behind targeted ambitions. A key reason is that CCS ... -
Optimal experimental design for identification of hydrodynamic loading models
(Journal article; Peer reviewed, 2024)Hydrodynamic model-scale experiments are an intrinsic part of the design of marine structures, as they enable validating and calibrating the involved hydrodynamic numerical models. Such seakeeping experiments are generally ... -
