Ship Repair Cost & Man-Hour Estimator

Build a repair budget from physical scope and labor intensity instead of one lump-sum guess. Simple mode converts steel, piping, coating and other repair labor into a fast man-hour and cost screen. Advanced mode builds the estimate package by package with complexity, access, rework, overtime, materials, subcontractors, equipment, dock/berth cost, schedule capacity and owner economic exposure.

↑Need package-by-package repair pricing and schedule pressure?Advanced adds editable work packages, overtime, complexity/access factors, dock/berth charges, off-hire exposure, schedule capacity, stress cases and scope/labor sensitivity.

Repair Scope

Enter the physical scope you already know. Simple mode applies your own labor-intensity assumptions and keeps non-labor costs in one allowance.

Structural steel renewalInstalled tonnes.

Pipe renewal / fabricationMetres of repaired/renewed piping.

Surface preparation & coatingm² of blasting/preparation/coating scope.

Machinery / electrical labor allowanceDirect labor-hours for other repair work.

Labor & Cost Basis

Steel labor intensityman-hours / installed tonne.

Pipe labor intensityman-hours / metre.

Coating labor intensityman-hours / m².

Blended yard labor rateCurrency per direct labor-hour.

Materials, subcontractors, equipment & dock allowanceAll non-labor direct costs combined.

Repair contingencyApplied to labor plus entered non-labor cost.

↑Advanced repair-package estimateEach work package prices its own labor intensity, complexity, access, rework, labor rate, materials, subcontractors and equipment. Free-text descriptions remain screen/export only and are not sent to Tool Data.

Project Labor & Schedule

Labor intensity should be based on the yard, vessel, access, material, hot-work controls and repair method actually expected. The calculator does not provide universal ship-repair production norms.

Overtime labor share% of direct labor-hours.

Overtime premium% premium above base row labor rate.

Supervision / QA / indirect labor% of priced direct labor.

Productive hours / worker-dayNet productive repair hours.

Average workforce availableAverage productive workers available to this scope.

Target repair durationCalendar/work days on the planning basis selected.

Repair Work Packages

Calculated hours = quantity × MH/unit × complexity × access × (1 + rework). Labor pricing then applies the entered overtime mix. Material is quantity × material/unit.

Estimate Readiness Checks

Repair scope frozen enough for budget useWork list and quantities have been screened against inspection findings. Drawings / material grades availableCritical renewal details and material requirements are known. Access, gas-freeing and staging surveyedConfined spaces, hot work and temporary access are reflected in the estimate. Major subcontract/vendor scopes identifiedSpecialist work is not hidden inside the yard labor rate. NDT / test / class closeout includedInspection, testing and closeout activities are in the work list. Dock/berth sequence screenedTarget duration and workforce reflect realistic work overlap.

Stress Cases

Stress the estimate without changing the base inputs. Productivity is entered as a percentage of base productivity; below 100% increases labor hours.

5×5 Scope × Labor Rate SensitivityTotal repair cash cost as physical scope and labor pricing move away from the base case.

Advanced Stress CasesBase scope stays unchanged; each case recalculates cost, man-hours and schedule pressure.

Model boundary: This is a repair-budget and labor-planning screen, not a shipyard quotation, class-approved repair specification or production standard. Labor intensity varies materially with vessel type, yard, country, repair method, access, steel grade, hot-work controls, staging, weather, work-front availability, material lead time, class/flag requirements, testing and emergent work. Use yard/vendor quotations and approved repair specifications when available. Off-hire/economic exposure is shown separately from repair cash cost so commercial impact is not confused with yard expenditure.
