Motion, Forces and Lashing Checks in One Environment

SecureLoad Acceleration & 3D Lashing uses realistic vessel motions and cargo geometry to check accelerations, forces and lashing layouts before you sail.

Built for heavy-lift and complex breakbulk, it helps engineers and port captains design lashings that meet standards and are practical on deck.

From Rule-of-Thumb to Physics-Guided Lashing

SecureLoad Acceleration & 3D Lashing helps you move beyond generic tables and rule-of-thumb factors.

By capturing seaway loads, applying recognised standards and documenting every assumption, it reduces rework on deck and disputes with surveyors or clients.

Realistic Acceleration Environment

Realistic Acceleration Environment

Use vessel, route and sea-state assumptions to derive accelerations, instead of relying on generic “worst-case” factors for every job.
3D Lashing on Real Geometry

3D Lashing on Real Geometry

Design lashings directly on realistic cargo meshes and deck structures, so what you calculate matches what crews can actually rig.
Transparent, Documented Checks

Transparent, Documented Checks

Generate clear documentation that shows assumptions, forces and utilisation against standards—so surveyors and clients can trace how you got to “safe”.

What Acceleration & 3D Lashing Covers

Acceleration & Loads

Sea States and Motion Envelopes

Define sea states, routes or motion envelopes according to your engineering approach, rather than relying on fixed generic factors.

Accelerations at Cargo CoG

Compute accelerations at the cargo centre of gravity and other key points that drive seafastening loads.

Forces on Supports and Lashings

Translate accelerations into forces on supports, grillages and lashings so you see where loads actually go.

Lashing Design

3D Lashing Layout

Place and configure lashings directly in 3D on real cargo and deck geometry—angles, connection points and pre-tension included.

Checks Against Standards

Evaluate lashing arrangements against relevant codes and criteria, using methods aligned with recognised guidance.

Utilisation and Safety Margins

See utilisation factors, safety margins and potential weak links so you can strengthen or simplify the arrangement before it reaches the deck.

Outputs Built for Surveyors and Clients

Technical Outputs

Load Case Summaries

Summaries of accelerations, forces and utilisation for each load case, captured in a form engineers and surveyors can follow.

Lashing Lists

Structured lists of lashings with types, positions, angles and pre-tensions for each arrangement.

Utilisation vs. Limits

Clear utilisation figures against allowed limits, highlighting where margins are tight or where reserve capacity exists.

Visual Documentation

2D / 3D Arrangement Views

2D and 3D views of lashing arrangements on the actual cargo and deck geometry, ready to drop into method statements and reports.

Critical Points & Remarks

Call-outs for critical points, special requirements and engineering remarks that need attention on board or in review.

Export for Approvals & Records

Export documentation to PDF and image formats so surveyors, clients and internal stakeholders can review, approve and archive the work.

Review and sign off lashing arrangements with a clear view of assumptions, forces and margins before the job reaches the quay.
Third-Party Engineering Partners & Surveyors
Receive transparent calculations and visuals you can audit, with options for view-only access to review arrangements efficiently.

Example Lashing Cases

Tall Unit on MPP Deck

Checked motions and lashings for a tall, wind-sensitive unit close to cranes and masts, verifying forces and margins for multiple headings and sea states.

Multi-Point Heavy Lift

Evaluated accelerations and lashing loads on a multi-point lifted component, identifying weak links and refining the arrangement before issuing final seafastening drawings.

Barge Transport with Large Modules

Assessed motions and lashings for large modules on a towed barge, confirming forces on grillages and lashings across critical route segments.

Frequently Asked Questions

Q1. Which standards and practices can this support?

SecureLoad Acceleration & 3D Lashing is designed to align with recognised industry guidance and class-aligned practices for motions and seafastening checks. The exact standards and methods used on your projects can be configured during setup so they match your engineering practice and class expectations.

Yes. Company-specific safety factors, allowable utilisation levels and rule sets can be configured into the workflow. That way, engineers work within the same rules they already follow, but with clearer transparency on how each assumption affects the results.

Both approaches are supported. You can work with parametric “blocks” (dimensions, weight, CoG) for many cases, and use detailed 3D meshes where geometry is critical—for example, for complex project pieces or tight clearances.
Once your vessels and basic libraries are configured, engineers can usually set up and run a typical lashing case in a short focused session. Most teams become comfortable after a few guided examples based on real projects they’ve already delivered.

Yes. Surveyors and clients can review arrangements via exported reports and views, and view-only access options can be enabled where appropriate. This lets them see the geometry, lashings and key results without being able to change the engineering work.
