Marine Loading Software, Built for Your Vessel

We develop ship-specific loading and stability software for onboard and office use, based on your vessel’s approved data and plans.

Start a Vessel Software Project

Shipowner-Focused Development

We build ship-specific loading software used by ship officers and shore teams to plan loading/ballasting, and check stability and strength. We deliver a complete package: software + documentation support.

For shipowners, this is delivered as a software development / programming contract for your vessel or fleet—built around the same operational focus as LoadMan, but tailored to your ship data and company workflows.

⚓

Vessel-Specific

Built from your approved stability booklet and plans—so results match your ship data.

🧾

Operations-Ready

Clear outputs and printable reports for onboard work and office review.

✅

Approval-Oriented

Type-approval oriented development with ship-specific approval support when required.

Key outcomes for shipowners

  • Safer loading decisions and faster planning onboard
  • Standardized reporting across fleet operations
  • Easier compliance support during audits and surveys

What the Software Includes

A clean, shipboard-practical feature set—built around real operational workflows.

Core operational features

  • Create loading conditions (cargo + ballast)
  • Calculate drafts (F/A/mean), displacement, trim, and propeller immersion ratio
  • Longitudinal strength checks (Shear Force / Bending Moment vs allowable limits)
  • Intact stability outputs (KG, GM, and GZ curve—where available from vessel data)
  • IMO intact stability criteria checks (as applicable to ship type and approved data)
  • Draft survey tools with sounding/ullage workflows and printable reports
  • Trim & draft updates when loading, discharging, or shifting weights
  • Trim adjustment using two (2) or three (3) specified compartments (where applicable)
  • Cargo distribution tools for bulk cargoes, including percentage distribution
  • Draft-restricted port planning for bulk cargo distribution (load/discharge ports)
  • Stowage factor tools (conversion and partially-loaded hold estimation)
  • Hold KG estimation using stowage factors (including mixed stowage factors, where applicable)
  • Lightening and remaining cargo planning to reach target/max draft (where applicable)
  • Loadable cargo and departure trim planning to target even-keel drafts (as applicable)
  • Loadline-limit checks and loadable cargo calculations (where applicable)
  • Shifting tools to obtain a desired trim—or while keeping trim constant
  • Draft and trim corrections for different water density
  • Air draft calculations and interpolation

Graphs, reports & specialized modules

  • Shear Force and Bending Moment curves over the ship's length
  • Graphical SF/BM display with actual and percentage values
  • Stability calculation graphs (including GZ curve display)
  • Bar-graph view of cargo loading status
  • Draft survey reports with sounding reports
  • Grain stability calculations with printouts (where applicable)
  • Non-cargo tank volumes and sounding reports with printouts
  • Tanker cargo volumes and ullage reports with printouts
  • Dew point calculations (where applicable)
  • List/heel corrections (calculate opposite-side drafts when listed)
  • Trimming tables (where applicable)
  • Loading sequence form preparation and calculation support

Works for common vessel types

  • Bulk carriers
  • General cargo
  • Container vessels
  • Tankers
  • Ro-Ro (and similar)
See LoadMan Product Details

Approvals, Licensing & Support

Licensing approach

  • Licensed for vessel operational use (onboard)
  • Installable on multiple onboard PCs (site-style use onboard)
  • Optional office copies for managers/owners
  • Designed for real shipboard constraints (offline-friendly)

Exact terms can be adjusted to match your fleet needs and commercial policy.

Type approval + ship-specific approval support

  • Type-approval oriented development to meet classification expectations
  • Ship-specific approval may still be required depending on vessel and class rules
  • Support with documents, calculation outputs, and model details for review
  • Assistance during verification when needed

Ship Data We Request (Typically Under NDA)

We don’t expect proprietary plans on first inquiry. After NDA/award, we can request the documents below and agree a secure method to share them.

Stability Booklet (expected contents)

  • Principal particulars
  • Capacity tables
  • Hydrostatic tables
  • Hold diagram and table (Volume & KG)
  • Tanks diagram or table (Volume, KG, and Inertia)
  • KN or GZ curves or table
  • Flooding/downflooding angle curves or table
  • Windage area table/curve (including Z curve)
  • Waterline length curve/table
  • Shear Force & Bending Moment data (allowables, buoyancy tables, calc sheets, sample cases)
  • Loading conditions (normal ballast, full load homogeneous, container, mixed cargo)
  • Container bay plan (40’ & 20’)
  • Tank / ullage table (sounding tables)
  • Propeller immersion data
  • Grain Loading Manual

Plans / drawings

  • Capacity plan
  • General arrangement plan
  • Lines plan
  • Bonjean table or curve
  • Light weight distribution
  • Hull Structure Manual / structural drawings

Delivery Workflow

A straightforward process that works well for single vessels and fleets.

1️⃣

Data collection

You share vessel name/IMO and your goals. If needed, we sign NDA and set a secure document handover.

2️⃣

Software development

We build the ship-specific software and tables required for calculations.

3️⃣

Software build + review

We deliver the software package and review sample loading conditions with you.

4️⃣

Approval support (if required)

We help prepare submission materials and support ship-specific approval processes.

Get a Quote

Pricing is based on your vessel and scope of work — contact us for a quotation. To get started, just share the basics: vessel name, IMO number, and what you want to achieve. If your documents are proprietary, we can arrange an NDA and a secure handover before requesting ship data.

Send your inquiry to deckmastermarine@gmail.com and we'll get back to you with pricing.
