PT-BR
Um tote tank é um Vessel que porta uma Função de Armazenamento Portátil, fornecendo contenção transportável e segura de uma ampla gama de líquidos — incluindo produtos químicos para processos de óleo e gás, processos de perfuração, líquidos residuais e combustível de aviação — tanto em armazenamento quanto em transporte entre locais.
Formal Axioms
Semi-formal (Aristotelian)
Every tote tank is a vessel that bears a portable storage function and has a frame as a component part, designed to protect the tank and its fittings.

Axiomatization Decision Log
1
Identity-Giving Function
Function class
PortableStorageFunction
⊑ StorageFunction
Realized in
PortableStorageProcess
⊑ PlannedProcess
Every source defines tote tank as a tank whose reason for being is transportability of its stored contents ("supposed to be transported"; "transportable... container"). This is more specific than plain StorageFunction (already enriched via storage tank/basin/hopper/silo/accumulator/pressure vessel) — every realisation of PortableStorageFunction is a realisation of StorageFunction (liquid is held), but not every StorageFunction realisation is portable (a fixed storage tank is not). This is the Subtype case, not Reuse: co-extension would require every storage-function-bearer to also be transportable, which is false for the sibling classes already in the ontology.
2
Genus Determination
Vessel
Source hierarchies offer ARTEFACT, TANK, and Static Equipment as parent candidates, none of which is itself an enriched class in this ontology. The established, already-enriched genus for containment/storage equipment of this kind is Vessel (used consistently by storage tank, basin, hopper, silo, accumulator, pressure vessel, pig launcher, pig receiver) — its own function is ContainmentFunction, genus_bfo_root Assembly, and it is the most specific genuine superclass available given no separate 'Tank' class exists yet in the ontology. Following the sibling pattern (storage tank -> Vessel) rather than introducing a new unenriched 'Tank' genus keeps tote tank correctly inheriting Vessel's containment axioms.
3
Necessary Parts
| Part class | Parent | Relation |
|---|---|---|
| Frame | MaterialArtifact | hasComponentPartAtAllTimes |
Frame identified via Step 2b secondary-source research (DNV-ST-E271), absent from the three terms.db definitions alone.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfLiquid
— a wide range of liquids including chemicals for oil and gas processes, drilling processes, waste liquids, and aviation fuel (ISO 15926)
Outputs (O)
PortionOfLiquid
— the same liquid portion, composition and phase unchanged, discharged after storage and/or transport
Transformation (T)
a portion of liquid is contained and physically relocated between locations without change in composition or phase
The signature mirrors Vessel's own containment signature (liquid in, same liquid out) — the differentiating characteristic (transportability) is a property of the process context (repeated relocation) rather than a distinct participant type, so it is captured in the transformation phrase, not as a new input/output type.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Cross-Standard Observations
CFIHOS and POSC Caesar's definitions are textually identical, suggesting a shared or derived source; ISO 15926-4 is the sole source carrying operational/safety context (offshore deployment, specific liquid categories) that motivates treating transportability as a genuine functional differentia rather than an incidental property.
Reviewer Notes
generation_path=skill_session; Step 2b secondary research performed post-hoc via WebSearch+WebFetch+pdftotext fallback (DNV-ST-E271 PDF was unreadable via WebFetch's own extraction, recovered via pdftotext per CLAUDE.md's access-discipline fallback) after the initial proposal was stored without it -- see the session's finding on this gap in the skill.
