Hull Steel Renewal Weight, Plate, Labor & Drydock Cost Tool
Turn a steel-renewal scope into purchased tonnes, fabrication hours and drydock economic exposure. Simple mode sizes plate weight from area and thickness, adds procurement wastage, fabrication labor, coating/staging and incremental dock days. Advanced mode builds the renewal package member by member with weld length, access complexity, NDT share, coating area, transport, scrap and schedule impact.
Fast Steel-Renewal Budget Screen
Simple mode assumes flat plate equivalent area and uses 7.85 t/m³ steel density. Fabrication hours should include crop, fit-up, welding and normal handling if those are not priced elsewhere.

Steel-Renewal Register
Each row can represent a plate, strake, insert group, bracket set or other flat-plate-equivalent renewal item. Grade factor is a user-entered purchase-price multiplier, not a class rule.
| Structure / item | Area m² / item | Thickness mm | Qty | Grade price factor | Wastage % | Weld length m / item | Fabrication h / net t | Access complexity | NDT share % | Coating area factor | Removed weight factor |
