Custom Containers
LOP ships with a built-in catalog of 50 container and vehicle types covering the equipment most shipments use. In the large majority of cases you won't need a custom definition — you pick the matching type from the Container Library and start planning.
There is currently no self-service tool to build a fully custom-dimensioned container in LOP. The built-in catalog is the supported way to choose your vessel. If your equipment isn't represented, see If your equipment isn't in the catalog below.
What the Built-In Catalog Covers
Open Container Library from the left sidebar to browse and enable types. The catalog spans every transport mode:
- Sea — ISO dry containers (20'/40' General Purpose, 40'/45' High Cube), reefers, open-tops, flat racks, and ISO tank containers.
- Road — North American dry vans (48'/53') and box trucks; European curtainsiders (standard and mega) and box trailers; the flatbed & open-deck family (flatbed, step deck, double drop / lowboy, removable gooseneck, EU platform); and specialized equipment including liquid tankers and the 25.25 m LHV / EuroCombi road train.
- Air — IATA Unit Load Devices (ULDs) with their certified contoured dimensions and weight limits.
See Standard Containers for the full per-type specifications, and Container Preferences for how to choose which of these appear in your editor.
If Your Equipment Isn't in the Catalog
If your shipment uses a vessel that isn't represented in the catalog:
- Pick the closest matching type. Most non-standard trailers and intermodal units are dimensionally close to a catalog type. Choosing the nearest match (and erring toward the smaller usable envelope) keeps your plan conservative — it won't promise space the real vessel doesn't have.
- Tell us what you need. If you regularly ship in equipment the catalog doesn't cover, contact support@lop.tools with the make/model and certified internal dimensions. We expand the catalog based on what customers actually use.
When you substitute the closest catalog type, double-check the internal dimensions and max payload against your real equipment before relying on the plan — a plan is only as accurate as the vessel it was built against.
