Idwal Condition Data for Maritime Insurance

Designed specifically for underwriting, risk assessment, and insurance pricing, Idwal’s vessel condition data can be integrated seamlessly into existing maritime insurance systems via API or data import. This allows insurers to move beyond assumptions and assess vessels based on real-world condition and not rely on traditional risk scoring methods that do not take into account the physical state of a vessel. With access to real-time vessel data and estimated Idwal Grades for over 60,000 ships (15% of which have been physically inspected by Idwal), users can better differentiate risk, detect issues earlier, and respond with greater precision.

Whether adjusting premiums dynamically, identifying high-risk exposures, calibrating predictive loss and pricing models, or incentivising well-managed fleets, Idwal’s data allows insurers to price more accurately and optimise portfolio performance with confidence.

Integrate ship condition data directly into your platform

Our comprehensive API, developed by our in-house engineering team, allows partners to integrate Idwal’s vessel condition data directly into their existing systems and platforms—enabling automation of pricing models or risk algorithms within your current workflow, using existing tools.

Customer systems receive the latest estimated or verified Idwal Grades every day, with vessel grading becoming more accurate as we add more verified grades to your system.

Data in a format and frequency that suits your business

Alternatively, for organisations that prefer scheduled data delivery over system integration, Idwal offers flexible data snapshot and import options. Data can be provided on a monthly, quarterly, or annual basis, depending on your operational cadence and analytical needs. These exports can include vessel condition data, estimated Idwal Grades, deviations from average grade, and other key risk indicators—structured to align with your internal models and workflows.

What data is available for the insurance sector?

With data from over 12,000 inspected vessels creating a statistically significant representation of market conditions, Idwal's unique and inspection-led modelling delivers unmatched maritime intelligence through comprehensive coverage, exceptional accuracy, and global fleet analysis.

Grades, comparisons, and estimated grades are of particular interest to the Insurance sector, allowing for advanced risk modelling and pricing, loss model calibration, and greater optimisation of portfolios.

Using the deviation from average Idwal Grades for a particular metric, insurers can find clear correlations - providing clear signals of potential risk.

Increase model accuracy, screen potential clients & adjust premiums on a dynamic basis

Idwal data enhances your ability to refine actuarial models and accurately predict future risk outcomes. By integrating this data via API or import, insurers can move beyond static pricing and dynamically adjust premiums to reflect a vessel’s actual risk profile—ensuring more accurate pricing, better risk alignment, and improved portfolio performance.

Most of all, Idwal's screening tools allows Insurers to look at the condition of a potential client's fleet before any conversation about adoption into your insurance portfolio. Know the risk of your decision before any ink is applied to a contract.

Using this utterly unique dataset allows our customers to get competitive on price and well ahead of the competition.
