Drydock Project Critical Path, Work Package & Schedule Overrun Tool

Turn a docking specification into a dependency-based plan. Compare original work scope with current progress, yard workfront capacity, contractor availability, approved changes and downtime. See which work packages control redelivery and where realistic recovery measures can reduce cost exposure.

Data

Fast docking screen: 10 inputsHull preparation comes first. Steel/coatings and machinery work then proceed in parallel, with coatings dependent on steel and commissioning after both paths. This is a simplified project network, not a contractor-loaded schedule.

Docking Project Snapshot

Superintendent / shipyard planningBuild a resource-constrained schedule using the four registers beneath the charts. Baseline uses full contracted work. Forecast starts at the entered status day and schedules remaining work, known changes and interruptions. Partial completion is assumed measured in work completed, not elapsed days.

Scheduling and safety boundary: This is a planning model, not class approval, yard authorization, contractual liquidated-damages advice or a live safety permit. Class survey scope, docking constraints, hot work, confined-space controls, materials, trials and certification must be verified with the shipyard, flag/class and competent specialists. The Advanced scheduler permits quarter-day work segments and is not a full shift-by-shift enterprise scheduler.

Work Package & Dependency Register

Every active task requires a unique ID. List predecessor IDs separated by commas; cycles, unknown IDs and crew requirements exceeding trade capacity block Calculate. "Progress" represents physically completed work. Remaining work is simulated from the status day.

Use	ID	Work package / scope	Trade	Duration days	Predecessor IDs	Crew teams	Complete %	Budget USD	Safety gate	Baseline end	Forecast end

Contractor / Trade Capacity Register

Crews are simultaneous work teams, not headcount. Crew mobilization is measured from project day zero. The scheduler prevents competing tasks from using more teams than available.

Use	Trade	Available teams	Mobilize day	Daily team cost USD	Owner / contractor

Change Order & Discovery Register

Approved change order days and costs are applied only to the selected work package in the forecast. Pending rows are visible in the dispute/scope board but are not automatically added as committed costs.

Use	Change / discovery	Work package ID	Extra days	Cost USD	Decision	Responsible

Dock Closure, Hold & Verification Register

Closure rows suspend all active work during the entered absolute day window. Verification rows may be flagged critical, which creates a separate handover hold. An unverified safety item is never treated as authorization to proceed.

Use	Hold / check	Type	From day	Duration days	Critical?	Status	Responsible
