Abstract:
Digital twin technology has matured from a visualisation aid into a decision grade engineering tool for offshore asset integrity management. This paper reviews the state of the art in 2026 for digital twin applications covering two complementary equipment domains: static equipment, including pressure vessels, piping, pipelines, risers and structural systems, and marine mechanical equipment, including pumps, compressors, turbines, cranes and mooring machinery. The review synthesises recent advances in hybrid physics and data driven modelling, uncertainty quantification, envelope monitoring, edge computing and twin assurance frameworks such as DNV-RP-A204. It examines how predictive twins now feed risk-based inspection programmes under API 580 and API 581, replace calendar-based inspection with condition and risk informed strategies, and integrate with computerised maintenance management systems and permit to work workflows. Because offshore digital twins sit at the intersection of many disciplines, the review also draws systematically on adjacent peer reviewed literature spanning occupational safety and risk management, project governance, enterprise information systems, data governance, remote sensing and inspection robotics, predictive maintenance engineering, predictive analytics, artificial intelligence governance, industrial internet of things sensing, procurement and supply chain management, energy transition engineering, operational excellence and operational technology cybersecurity. Case evidence indicates measurable reductions in inspection cost, offshore exposure hours and unplanned downtime, alongside improved defensibility of life extension decisions for ageing assets. Persistent challenges are identified in data quality and standardisation, model validation, organisational readiness and cybersecurity. The paper concludes that the principal frontier is no longer computational capability but assurance: demonstrating, with quantified uncertainty and auditable governance, that a twin is trustworthy enough to carry safety critical integrity decisions.
