Life Cycle Support

A remnant life assessment evaluates how much safe, serviceable life remains in a piece of equipment based on its fatigue history, cumulative usage, and current condition. You would typically need one when equipment is approaching or has exceeded its original design life, when inspection findings reveal degradation such as cracking or corrosion, or when you want to extend operations beyond the original certification period. We review fatigue hotspots, cumulative damage factors, and corrosion allowances, then provide clear recommendations on whether the asset can continue operating, needs remediation, or requires replacement.

We work with whatever data is available. Using your survey reports, NDT results, and any operational records, we classify defects against a structured framework, assess the structural significance, and engineer a reinstatement concept where needed. Where history is incomplete, we apply conservative assumptions and document them transparently. The output is an evidence-based "as-left" pack that gives you and your class society a clear picture of the current condition and the engineering justification for continued operation.

We define the inspection and condition monitoring strategy — including risk-based inspection plans, hold and witness points, and the condition KPIs that matter for your equipment — but the physical inspections are carried out by your own teams or third-party inspectors. Once the results come back, we assess the findings against the acceptance criteria, update the condition record, and advise on any follow-up actions. This keeps the process independent and means you are not tied to a single inspection provider.

We have worked across a wide range of vessel types, from dredging vessels through to jack-up installation vessels selected for offshore wind campaigns. Wind installation work is particularly demanding — tall turbine towers, nacelles, and foundation components induce significant local loadings into the vessel superstructure during transit and installation. We typically design the sea-fastening arrangements for individual turbine components, analyse how those loads transfer into the hull structure, and assess any damage sustained during transit to and operations at the installation site. Where we identify issues, we engineer modifications to the hull superstructure to restore or improve capacity. The output is a fully detailed analysis and damage assessment report that gives you everything you need to engage directly with your classification society — whether that is DNV, Lloyd's Register, Bureau Veritas, ABS, or others.
