Steel Coil Loading, Tanktop Strength & Dunnage Tool
Steel Coil Loading, Tanktop Strength & Dunnage Tool
Screen steel-coil stowage against the vessel's approved tanktop and local loading limits, estimate dunnage contact pressure and line load, cross-check coil mass from geometry, test a simplified securing-force case and identify the controlling structural zone before loading.
Single Coil Block
Simple mode assumes uniform load sharing among bottom-tier support positions. Use Advanced if upper-tier geometry, mixed coil weights or local structural zones create unequal support loads.
Vessel & Approved Structural Basis
Enter limits from the approved loading manual, steel-coil loading plan, class-approved calculation or other vessel-specific structural information. No universal steel-coil tanktop limit is assumed.
Mixed Coil / Structural-Zone Register
Model mixed coil sizes and different structural zones separately. A row name is for on-screen use only and is never sent in Tool Data.
| Row / zone | Bottom | Upper | Coil t | OD mm | ID mm | Width mm | Zone L m | Zone B m | Dunnage lines | Board width mm | Bearing length m | Local limit t/m² | Line limit t/m |

Simplified Securing-Force Screen
This is intentionally not a duplicate of the full Ship Universe Cargo Securing & Lashing tool. Enter effective securing-device capacities after all MSL/CS/angle/connection reductions from the approved CSM or cargo engineering.
