Analysis engine

From cargo data to securing decision

SQ-SFA keeps the full seafastening workflow connected: case setup, stowage view, securing configuration, directional assessment and final report output.

Choose access plan
01 · Case setup

Set up the engineering case in one workspace.

SQ-SFA keeps the workflow clean: cargo geometry, CoG, weight, friction, vessel condition, motion input, environmental input and securing capacity are arranged for direct engineering review.

02 · Arrangement control

Review the stowage arrangement visually.

Automatic stowage output helps buyers see exactly what the software does: it turns engineering input into useful plan and side-view arrangement evidence.

03 · Securing setup

Build securing groups around the actual arrangement.

The page emphasises that securing is not one-size-fits-all. Users can set up multiple securing groups, define components and represent different project arrangements with better control.

04 · Output confidence

Issue clear calculation evidence.

The final message is simple: SQ-SFA helps engineers move from raw cargo data to a polished calculation report faster and with stronger presentation quality.

SQ-SFA V3.1 workflow

Updated 3D visual workflow for stowage, grillage and cleat review

SQ-SFA V3.1 adds a more practical visual workflow around Global Isometric review, Cleat Design and 3D grillage/support modelling while keeping the calculation package focused on seafastening, deck support and securing checks.

SQ-SFA V3.1 Global Isometric cargo, grillage and cleat arrangement view
Global Isometric

Review the full cargo, grillage and seafastening arrangement in one 3D scene.

The updated Global Isometric view supports a clearer visual check of cargo placement, support/grillage locations, cleat or seafastening arrangement and colour overlay for engineering review. It helps the user confirm the physical arrangement before issuing calculation output.

SQ-SFA V3.1 Cleat Design 3D plate assembly view
Cleat Design

Build cleat plate assemblies before assigning them to cargo securing.

Users create the required Cleat Design items first, define the cleat geometry, orientation and weld basis, then assign the cleat to the intended cargo/securing arrangement. This keeps the cleat design basis separate from the visual placement workflow.

SQ-SFA V3.1 3D grillage and cleat model visual style
3D Grillage / Support

Use the 3D support model to understand the load-path arrangement.

The 3D grillage/support view gives a consistent visual style for support modelling and arrangement checking. It remains a practical engineering visual and load-path workflow, not a replacement for detailed structural FEM where project approval requires it.

Mandatory cleat workflow: Create all required Cleat Design items first, determine which cargo each cleat is intended for, go to Global Isometric, arrange each cleat position per cargo, and only use Duplicate after the initial placement has been validated.
Report output samples

SQ-SFA report modules that sell the engineering clearly

The sample section follows the actual SQ-SFA report structure: stability basis, cargo stowage, summary checks, one representative detailed cargo calculation, directional load breakdown and conclusion. Each screenshot is matched to the exact explanation below it.

SQ-SFA GM GZ calculation basis report module
01 · GM / GZ Calculation Basis

Visible stability basis before the securing result is reviewed.

SQ-SFA presents the GM / GZ calculation basis directly in the report so the reviewer can see the stability reference used by the assessment. The module includes lightship, ballast and consumables, cargo design weight, combined LCG / TCG audit, displacement at auto draft, support weight and maximum draft / draft margin.

  • Gives the report a transparent stability and draft basis.
  • Shows the calculation reference before detailed securing checks.
  • Helps reviewers separate software audit basis from formal class stability approval.
SQ-SFA cargo stowage plan port side and starboard side report module
02 · Cargo Stowage

Automatic plan, port side and starboard side stowage views.

The cargo stowage module turns cargo input into visual report output. It shows cargo position against AP, CL and BL references, including plan view, port side view and starboard side view. This helps the user review the deck arrangement visually before checking the calculated securing demand.

  • Automatically illustrates cargo position from the entered case data.
  • Shows deck line, draft reference and cargo elevation in a clean report view.
  • Makes the report easier for client, vessel, yard and project teams to understand.
SQ-SFA analysis summary table with cargo utilisation and overall status
03 · Analysis Summary

Case-level result table for all assessed cargoes.

The analysis summary gives a compact overview of the full seafastening case. It lists cargo-by-cargo WCF weight, friction coefficient, directional utilisation, tipping status, coverage status and overall result so the governing items can be identified quickly.

  • Summarises multiple cargoes in one clear engineering table.
  • Highlights utilisation and pass/fail status without searching through pages.
  • Supports fast review of whether the arrangement is ready or needs action.
SQ-SFA one cargo detailed calculation report module
04 · Detailed Calculation per Cargo

One representative cargo calculation page.

This sample intentionally shows one cargo only. The detailed cargo page presents the core calculation values for a single cargo, including WCF weight, CoG, station location, normal load, friction, motion correction, acceptance UC limit, securing workflow, directional checks and securing capacity output.

  • Uses one cargo as a clean representative detailed calculation example.
  • Shows the key values behind the cargo-level pass/fail result.
  • Gives reviewers a traceable standalone calculation record for each cargo.
SQ-SFA directional load breakdown table with demand resistance and check status
05 · Directional Load Breakdown

Demand versus resistance shown by direction.

The directional load breakdown shows how the securing check is built up. Forward, aft, port, starboard, up and down directions are presented with motion force, air / wind force, current force, wave force, total demand, resistance and check status.

  • Separates force components instead of hiding the result in one number.
  • Shows exactly which direction governs the securing assessment.
  • Provides a strong technical basis for pass/fail and utilisation review.
SQ-SFA conclusion report module with final assessment statements
06 · Conclusion

Final assessment statement for the report package.

The conclusion module closes the report with a clear statement of the assessed condition, calculation coverage and result context. It links the calculation output back to the cargo arrangement, accepted basis, governing checks and engineering judgement.

  • Turns the calculation package into a readable engineering conclusion.
  • Supports client submission with a clear final assessment section.
  • Helps project teams understand the result without digging through raw tables.
