Lifecycle perspective on uncertainty and value robustness in the offshore drilling industry

Hydraulic vs. Electric: A Review of Actuation Systems in Offshore Drilling Equipment

“…-noise emission of equipment (Rahman and Abdullah, 1991) -faults on induction motors (IMs) (Thorsen and Dalva, 1995) and (Mendel et al, 2009) -wireless technology (Petersen et al, 2008) -needs for technological development (Springett et al, 2010) -increase of value robustness (Allaverdi et al, 2013) -actuation types of intelligent completion systems (Potiani and Motta, 2014) -heave compensation systems (Woodacre et al, 2015) -electric ship propulsion (Hansen and Wendt, 2015) -diagnostics and prognostics of offshore wind turbines (Kandukuri et al, 2016) not much work is reported on benchmarking electric and hydraulic drives in a broader perspective, specifically for offshore drilling applications. The current paper fills this gap.…”

A methodology for identifying flexible design opportunities in large‐scale systems

“…This paper addresses the need for flexible design methods, organized into a consolidated framework, 1 with an extended perspective of the technical system that includes external interactions—ie, an “end‐to‐end” methodology 12 that guides the user from change initiation to flexible design concepts (FDCs) and solutions. We focus on the concept generation phase, where “more research is needed to develop new procedures or adapt existing ones.” 13 We derived the method based on the need in the upstream oil and gas industry, where—due to social, technical, and environmental complexity, and the limits in planning operations strategically during design—a strong lack of uncertainty handling was observed, leading to design changes throughout the life cycle and making upgrades very expensive and suboptimal, especially postdeployment 14 . Hence, this paper presents a systematic methodology for designers to identify FDOs more comprehensively and earlier in the system design process.…”
