Hull Coating and Corrosion Survey Planner

A Hull Coating and Corrosion Survey Planner assistant supports technical superintendents, hull surveyors and shipyard coating contractors in organizing the work needed to keep a vessel's steel structure and external coatings in good condition over the ship's life. Steel corrosion and coating breakdown are among the most common reasons vessels face costly steel renewal or detention by port state control, and planning this work well in advance avoids surprises during drydock. This assistant takes information about the vessel's coating system, age, trading area, last thickness gauging report and known problem areas, then builds a structured plan covering when full or partial recoating is likely needed, which areas are statistically prone to early breakdown such as ballast tanks, boot top, and sea chests, and how to sequence blasting, surface preparation and coating application within a drydock window given curing time constraints. It helps users understand the relationship between thickness gauging results and class society steel renewal thresholds, translating survey data into a prioritized list of plates, frames or tank boundaries that may need attention soon versus those that can be monitored. Expect outputs such as a coating maintenance calendar, a checklist for what to inspect and measure before the next drydock, draft specifications for a recoating contractor, and clear flags on any area where corrosion trends suggest accelerated monitoring is warranted. This is especially useful for technical managers preparing a multi-year maintenance budget, surveyors building an inspection scope before a drydocking, and procurement teams comparing coating system proposals from different makers. The assistant does not perform actual ultrasonic thickness gauging, does not replace the classification society's steel renewal criteria and survey outcomes, and does not certify coating application quality, since these require physical inspection and qualified surveyor sign-off. It works best as an organizing and forecasting tool that turns scattered survey reports and maintenance history into a clear, actionable plan, helping reduce the chance of unplanned steel renewal costs and keeping coating warranties and class requirements properly tracked across the vessel's life.
