Abstract
A system is disclosed for converting an offshore survey scope of work into operational procedure packs such that planned intent, assumptions, source references, blocking conditions, and deliverable registers are preserved in machine-readable form before execution begins. In one embodiment a scope of work is decomposed into scope items; each scope item is expanded into a procedure pack capturing method steps, assumptions and exclusions, source references, operational tolerances, and a deliverable register; and the packs are linked back to the originating scope for traceability.
Technical field. Operational management software for offshore survey campaigns, in particular the decomposition of contracted scope into executable procedure packs with preserved assumptions and deliverable intent.
Technical Design Rationale
Scope documents and procedure manuals conventionally exist as separate artefacts. Assumptions, exclusions, and deliverable intent are often lost during manual translation.
The disclosed method addresses the technical problem of representing scope-to-procedure conversion as structured, reviewable procedure packs that retain originating scope references and operational constraints.
Background and operational problem
An offshore survey scope of work describes what must be achieved, but crews execute against procedures. Manual translation loses assumptions, tolerances, and deliverable intent.
A technical problem exists: how to decompose scope into procedure packs that preserve originating references, operational constraints, and deliverable registers in a form suitable for readiness evaluation and later reporting.
Inventive contribution
The inventive contribution is the structured decomposition of scope items into procedure packs that carry assumptions, source references, blocking conditions, operational tolerances, and deliverable registers while maintaining bidirectional links to the originating scope.
System overview
In one embodiment the system comprises a workscope intake; a scope-item normaliser; a procedure-pack builder; a tolerance and blocking-condition binder; a deliverable-register initializer; and a review surface presenting packs alongside their originating scope items.
Components
- Scope item
- A structured unit of contracted work with method references, quantities, and acceptance criteria.
- Procedure pack
- A reviewable bundle describing execution method, assumptions, source references, tolerances, blocking conditions, and deliverables.
- Assumption record
- Explicit statements of preconditions, exclusions, or environmental windows attached to a pack.
- Source reference
- Links to governing documents, specifications, or client requirements informing the pack.
- Tolerance binding
- Machine-readable operational limits attached to pack activities.
- Deliverable register
- Initial list of outputs the pack must produce, linked to scope acceptance criteria.
Data-model shape
- Scope item
- { description, quantity / extent, method ref, acceptance criteria }
- Procedure pack
- { scope ref, method steps[], assumptions[], source refs[], tolerances[], blocking conditions[], deliverable register[] }
- Assumption
- { pack ref, kind, statement, valid-from / valid-to }
- Deliverable intent
- { pack ref, title, format, acceptance criteria ref }
Workflow
- 01
Ingest scope
Scope of work is ingested and normalised into scope items.
- 02
Map methods
Each scope item is associated with execution methods and acceptance criteria.
- 03
Build packs
Procedure packs are composed with method steps, assumptions and source references.
- 04
Bind tolerances
Operational tolerances and blocking conditions are attached to pack activities.
- 05
Register deliverables
Deliverable intent is initialised from scope acceptance criteria.
- 06
Review
Packs are reviewed alongside originating scope before work-package decomposition.
UI / operational behaviour
In one embodiment a scope overview lists scope items; selecting an item opens its procedure pack with assumptions, source references, tolerances and deliverables visible in one review surface; edits to packs retain scope linkage; and review status is recorded before downstream decomposition.
Pseudo-code (high level)
buildPack(scopeItem):
pack = { scopeRef: scopeItem.id, steps: deriveSteps(scopeItem.method) }
pack.assumptions = extractAssumptions(scopeItem)
pack.sourceRefs = linkSources(scopeItem)
pack.tolerances = bindTolerances(scopeItem.method)
pack.deliverables = initDeliverables(scopeItem.acceptance)

Review modes
- Single reviewer
- Multi-role sign-off
- Versioned revision history
Example offshore use cases
- A geophysical scope item decomposes into a procedure pack recording survey-line assumptions, positioning tolerances, and deliverable formats before mobilisation.
- A client specification change updates source references on affected packs while scope linkage is preserved.
- Assumptions on weather windows are visible at pack review and flow into readiness evaluation downstream.
Benefits and technical effect
The system preserves scope intent through procedure definition; makes assumptions and tolerances explicit before execution; initialises deliverable tracking early; and maintains traceability from packs to originating scope.
Implementation details intentionally omitted
This disclosure is intentionally limited to system concepts, workflows, data-model shapes, state machines, UI behaviours, and alternative embodiments. Source code, exact algorithms, credentials, deployment configuration, customer-specific procedures, real project data, private reports, generative instruction workflows, and commercial terms are intentionally omitted and retained separately as confidential implementation material.
Commercial relevance
Survey managers reduce scope-to-procedure translation effort and improve review quality before mobilisation. Pack content requires verification against governing scope documents.
