Ship Universe Drydock Steel Renewal Tool
Hull Steel Renewal Weight, Plate, Labor & Drydock Cost Estimator
Turn a steel renewal scope into a shipyard-ready budget. Estimate installed tonnes, stock plate procurement, nesting waste, billable tonnage, benchmark man-hours, labor cost, coating and NDT extras, steel-work duration, drydock extension and off-hire exposure. Advanced mode handles multiple renewal locations with different thicknesses, access factors and curvature.
Steel Renewal Scope
Enter the finished renewal area and structural details. The estimator separates installed weight, purchased stock and yard billable weight.

Renewal Item List
Model each plate group separately so thickness, access, curvature, weld length and man-hour basis can vary.

Benchmark basis:
thickness-based labor mode uses a published ship-repair budgeting curve for
steel renewals, then applies location, curvature, higher-strength steel and
user-entered productivity factors. It is a budget benchmark, not a live yard
tariff. The estimator intentionally does not decide whether steel must be
renewed. Use approved thickness-measurement, class and repair-scope data for
that decision.

DNV hull survey planning
Enter steel renewal, labor, plate procurement and drydock assumptions to build the estimate.
Budget and drydock planning estimate only.
This tool does not determine class renewal criteria, minimum permissible
thickness, local or global hull-girder wastage limits, repair design, steel
grade acceptance, weld procedure, NDT scope or survey acceptance. Renewal
scope should come from approved thickness measurements, survey findings,
class requirements and repair drawings. Benchmark man-hours are intended
as a historical budgeting reference and can differ materially by yard,
location, quantity, access, weather, staging, production method, steel
grade, sequence, shift pattern and contractor productivity. Stock plate
availability, commercial plate dimensions, minimum yard billing quantities
and tariffs vary by yard and supplier. Advanced line-item plate counts are
conservative because they do not optimize nesting across different renewal
rows. Use current quotations before committing a project.
