The global standard for vessel assurance
The Idwal Grade: a transparent, defensible measure of vessel integrity, trusted worldwide.
The Idwal Grade is the maritime industry’s independent benchmark for vessel condition and integrity. Built from more than 500 inspection data points and governed by a single global methodology, it provides assurance that vessel condition is accurately assessed, comparable and defensible.
By converting complex technical findings into a transparent 0–100 score, the Idwal Grade enables owners, charterers, financiers and insurers to make faster, evidence-based decisions with confidence.
Every Grade is produced through the same quality-controlled process, ensuring consistency across fleets, regions and transaction types. This uniformity makes the Idwal Grade the trusted reference point for vessel assurance in global maritime markets.
Clarity
Thousands of inspection observations distilled into a single, intelligible signal of assurance.
Accuracy
Standardised inspections validated through central technical and analytical review.
Comparability
A globally applied framework that makes every Idwal Grade directly benchmarkable.
How it works
Surveyors capture 500+ data points, which are organised into 21 sub-grades, analysed with AI support, and combined into a final grade (0-100).
Every report includes charts, photos and context for quick visualisation of strengths and areas for improvement.
Idwal surveyors capture more than 500 verified inspection data points during each assessment. These are structured into 21 sub-grades, analysed using proprietary algorithms and reviewed through rigorous quality control before being aggregated into a final 0–100 Grade.
Reports include charts, photographic evidence and contextual explanation, allowing stakeholders to understand the headline Idwal Grade, the underlying condition drivers and areas for improvement.
Benchmarking and insight
With over 12,000 vessels benchmarked, the Idwal Grade supports comparative assurance across vessel types, ages and operators, strengthening risk assessment, operational planning and asset performance.

“Brokers clearly love Idwal reports. One explained that it essentially makes their job of selling a ship easier, in that they no longer have to persuade an owner to send its inspector to look at a vessel and instead can get an easy-to-read report. It also shunts some of the administrative tasks of report distribution onto someone else. The grade clearly has value."
