Cargo Securing & Lashing MSL, Sliding & Tipping Calculator

CSS Code Annex 13 • MSL / MBL • Calculated Strength • Friction • Sliding • Tipping • Cargo Securing Manual • 2026 PSC CIC

Cargo Securing & Lashing MSL, Sliding & Tipping Calculator

Screen non-standardized cargo securing from certified lashing strength through directional sliding and tipping resistance. Simple mode answers the fast securing-capacity question. Advanced resolves weak-link MSL, individual lashing groups, angles, friction, port/starboard and fore/aft capacity, tipping moments, corrective lashings and Cargo Securing Manual readiness.

Fast Cargo Securing Screen

Use approved CSM / lashing-software accelerations. Simple mode assumes the same certified MSL and vertical angle for all active direct lashings and zero horizontal deviation from the direction being resisted.

Each row is a load-resisting group. Quantity means the number of active lashings available in each selected direction. The weakest positive MSL among the lashing device, end fitting and deck fitting governs. Group labels remain on screen only and are not sent through Tool Data.

Cargo Securing Manual & 2026 PSC Readiness

Current inspection context: Paris and Tokyo MoU are conducting a joint Cargo Securing CIC from 1 September through 30 November 2026. These checks support preparation but do not replace the official 10-question PSC questionnaire or the approved Cargo Securing Manual.

Additional Securing / Rework Scenario

Engineering limitation: a green screen does not authorize carriage. The approved Cargo Securing Manual, approved lashing software where applicable, certified MSL/SWL markings, actual deck/fitting strength, cargo-specific sea-fastening design, route/weather criteria, class/flag requirements and the Master's judgment control.
Regulatory / technical basis: SOLAS cargo-stowage and securing requirements; IMO Code of Safe Practice for Cargo Stowage and Securing (CSS Code), including Annex 13; MSC.1/Circ.1353/Rev.2 Cargo Securing Manual guidelines. Annex 13 defines MSL as the securing-device capacity for service, requires the weakest applicable MSL in a series to govern, and uses calculated strength below MSL in balance calculations. The 2026 Paris/Tokyo MoU Cargo Securing CIC runs from 1 September to 30 November 2026. This tool requires approved accelerations/design forces rather than generating ship-specific Annex 13 acceleration tables.
