Barge Longitudinal Strength Calculator

1. MAIN DIMENSIONS

Input the main dimensions of the barge. Length must be ≥ 90m for S11 to apply.

Length (L) (m)

Breadth (B) (m)

Depth (D) (m)

Draft (T) (m)

Block Coefficient (Cb) (min 0.6)

Dimensional Ratios

2. STRUCTURAL CONFIGURATION

Input all structural details including plate thicknesses, bulkhead configuration, and stiffener details.

Plate Thicknesses (mm)

Component	As-Built (mm)	Corrosion Allowance (mm)	Net Thickness (mm)
Deck Plate			15.0
Bottom Plate			14.0
Side Shell			12.5
Long. Bulkhead			13.0
