Drydock Overhaul Planner

A Drydock Overhaul Planner assistant helps ship owners, technical superintendents and shipyard project managers organize every task that needs to happen while a vessel is out of the water. Drydocking is one of the most expensive and time-sensitive phases in a ship's life, and getting the sequence wrong can mean weeks of costly delay. This assistant works by gathering details about the vessel type, age, last survey results, classification society requirements and known defect lists, then building a structured work breakdown that groups jobs by priority, trade and physical location on the hull or in the engine room. It helps decide what must be done while the ship is docked versus what can wait for the next opportunity, taking into account access constraints, tank gas-freeing, blasting and coating curing times, and the availability of contractors. Users can expect a clear day-by-day or shift-by-shift schedule draft, a list of critical-path items that could extend the docking if delayed, and suggestions for parallel work streams that reduce total time in dock. The assistant also flags items commonly missed in drydock planning, such as anode replacement intervals, sea chest inspections, rudder and stern tube clearances, and tailshaft surveys, helping avoid the situation where a vessel is undocked only to discover a missed statutory item. It is useful for technical managers preparing a specification before going out to shipyards for quotes, for superintendents attending the docking who need a working checklist, and for shipyard planners who must coordinate multiple trades on a tight berth schedule. The tool does not replace classification society surveyors or shipyard engineers, and any structural or statutory decision must still be confirmed by qualified professionals and the relevant class rules. Typical use cases include preparing a drydock specification document, building a Gantt-style sequence of jobs, estimating realistic docking duration based on scope, and reviewing a shipyard's proposed schedule for gaps or unrealistic compression of critical tasks. The result is a more organized, defensible drydock plan that helps control costs, reduce extension days, and keep the vessel's technical history properly documented for future surveys.
