3D Stowage Planning for Breakbulk and Heavy-Lift Cargo

SecureLoad 3D Stowage Planner lets you design stows in 3D using realistic cargo meshes and deck models, not just 2D sketches and PDFs. Check clearances, CoG and key constraints early, and hand over stows that connect cleanly into loading computer and lashing workflows.

Plan Visually. Check Technically. Decide with Confidence.

SecureLoad 3D Stowage Planner gives you a browser-based 3D workspace for MPPs, deck carriers, barges and project cargo campaigns. You see cargo, decks and constraints the way they really are while still keeping a line of sight to the technical checks behind them.
Visual Deck & Hold Layout

Visual Deck & Hold Layout

Drag, rotate and position cargo directly on realistic vessel geometry - decks, hatches, coamings, obstacles and lashing areas included.
Constraint-Aware Planning

Constraint-Aware Planning

Plan stows with live feedback on clearances, CoG envelopes, visibility and access routes, so impractical layouts are caught early.
Multi-Port Scenarios

Multi-Port Scenarios

Build and compare multi-port plans with partial discharges, re-stows and backloading, without losing track of what’s on deck where.
Hand-Off to Engineering & Operations

Hand-Off to Engineering & Operations

Export 3D views, drawings and structured data for engineers, masters and port captains, ready for loading computer and lashing workflows.

Modules and Outputs

Modules

Core 3D Layout Workspace

Vessel and cargo shown together in a 3D workspace, with decks, holds and key structures modelled for realistic planning.

Multi-Port / Multi-Condition Planning

Plan multiple ports and conditions in one project—partial discharges, re-stows, backloading and return legs.

Libraries & Patterns

Shared libraries of vessels, decks, cargo types and stow patterns, so common setups don’t need to be rebuilt from scratch.

Linked Modules (SecureLoad Ecosystem)

Designed to connect with Acceleration & 3D Lashing and the Loading Computer, so 3D stows can feed into motion checks and loading cases.

Outputs

2D / 3D Views for Plans & Docs

Generate 2D and 3D views that can be used in stowage plans, method statements and client or surveyor documentation.

Measurements & Clearances

Show key measurements, clearances and simple annotations so reviewers can see why a stow works.

Cargo & Position Lists

Export structured lists of cargo items, positions and weights aligned with the 3D layout.

Export Formats

Support for image outputs and data files that can be used in reports, lashing design and loading computer workflows.

Connected to Lashing and Loading

Start where your team feels the most pain or roll out the full suite across ship and shore.

Loading Computer
To Acceleration & 3D Lashing
Use the same 3D stow geometry as the basis for motion and lashing checks—no redrawing cargo or decks in a separate tool.
Fleet Cargo Planner
To Loading Computer
Pass stow results (weights, CoGs and locations) into loading cases, so stability and strength checks reflect the real 3D layout.
3D Stowage Planner ico
To Fleet Cargo Planner
Use 3D layouts to support fleet-level decisions—showing which vessels can realistically take complex project and breakbulk stows.

Made for Heavy-Lift and Breakbulk Planners

Naval Architects & Cargo Engineers
Build and review 3D stows that match your calculations, not rough sketches—ready for lashing and loading checks.
Port Captains & Superintendents
Visualise proposed stows before vessels arrive, spot practical issues early and brief ships with clearer plans.
Heavy-Lift / Project Cargo Planners
Turn enquiry lists into visual options you can refine with engineering and present to clients or surveyors.
Chartering / Commercial Teams
Use clear 3D layouts to compare options and communicate what’s realistically possible on a given vessel.
HSEQ Teams & Surveyors
Review stow concepts with better visibility of clearances, access and arrangement before you sign off.

Example Stowage Scenarios

MPP Heavy-Lift Vessel

Combining containers, project pieces and a heavy unit on the same voyage—testing different positions and stack-ups to keep clearances, CoG and access routes within limits.

Deck Carrier – Multi-Port Campaign

Planning a multi-port discharge where tall cargo, cranes and backload units all need to move, without blocking key routes or breaking visibility requirements.

Heavy-Load Barge Tow

Placing large modules on a barge, checking overhangs and deck utilisation, and preparing a layout ready for motion and lashing checks.

Frequently Asked Questions

Q1. What cargo formats are supported (meshes, blocks, etc.)?

3D Stowage Planner is designed to work with both parametric “block” cargo (using dimensions, weight and CoG) and mesh-based cargo where detailed geometry is available.

You’ll be able to build a library of common items and import custom pieces for specific projects.

Yes. You can plan multi-port voyages with partial discharges, re-stows and backloading in a single project.

Different conditions (e.g. “After Port A discharge”, “Before Port B arrival”) can be stored and compared without losing track of what sits where.

Vessel and deck geometry is based on data supplied during the modelling phase (drawings, 3D models, etc.).

The aim is to be close enough for practical stow planning and clearance checks, and to stay consistent with the models used in SecureLoad’s engineering tools.

Yes. 3D stows can be shared as exported views, images or lightweight files so surveyors and customers can review layouts without needing full editing access.

Where appropriate, view-only access options can be explored for selected external stakeholders.

3D Stowage Planner is designed to sit alongside your current engineering stack.

Stow definitions and outputs can be used as input for motion, lashing and loading checks—either within the SecureLoad ecosystem (Acceleration & 3D Lashing, Loading Computer) or in your existing tools via exported data and views.
