Improve Underwriting with the Idwal Grade
Helping insurers improve pricing, risk and underwriting decisions with integrated, real-time vessel condition insights
Trusted by the industry
The Idwal Grade® is the leading global benchmark for ship condition and risk, built from a proprietary dataset, derived from large-scale, cross-sector inspections and enhanced with machine learning. The grade is derived from real inspections, covers technical, maintenance, safety, and ESG factors, enables dynamic, condition-led decision making, and is continuously updated to reflect current vessel conditions.

A standard you can trust
Idwal is the global leader in independent vessel inspections, data and intelligence. Since 2010, we’ve delivered unique survey and vessel assessment solutions to cross-sector markets.
In the last five years, we’ve completed over 15,000 physical ship inspections, helping to power strategic decisions for shipowners, financiers, asset managers, operators, and insurers worldwide.
With the intelligence from our inspections, augmented by machine-learning models, we have developed a unique and proprietary dataset to create the industry's first dynamic condition rating model, now covering more than 60,000 deep-sea assets, and available to hull underwriters worldwide.
