1. Purpose of the review
The review creates a verified basis for asset decisions. It brings the physical equipment and its records into one controlled picture instead of treating operations, maintenance, procurement, hire and finance as separate accounts of the same asset.
What the asset is
Identity, location, ownership, configuration, documentation and physical status.
Why it remains
Operational need, utilisation, criticality, redundancy and future demand.
Whether it is supportable
Condition, integrity, maintenance, reliability, inspection and certification.
What happens next
Commercial exposure, required disposition, accountable action and close-out evidence.
The method is informed by recognised asset-management principles concerning lifecycle value, performance, expenditure and risk. It is not presented as ISO certification, an ISO audit or a declaration of conformity.
2. Scope and boundaries
Define the review boundary before collecting data or walking the site. Record the sites, facilities, vessels, yards or operating areas; included systems and equipment classes; review period; future operating horizon; asset definition and reporting threshold; decision authority; access and permit restrictions; available evidence; and the applicable legal, Class, regulatory, company, client and contractual requirements.
The scope should state who owns the decisions and which specialist examinations require separately authorised competent persons. Typical inclusions are:
- owned assets;
- hired, rented and leased equipment;
- temporary plant;
- standby and emergency equipment;
- vendor-supplied packages;
- equipment within larger packages;
- portable and test equipment;
- lifting equipment and accessories where applicable;
- stored, mothballed or preserved equipment;
- spares and replacement equipment;
- transferred equipment;
- assets present but absent from registers;
- assets invoiced but not physically located.
3. Review method
- Define scope, authority and evidence requirements. Agree the decision owners, asset threshold, review horizon, access controls and governing requirements.
- Assemble the source records. Obtain registers, CMMS data, purchase orders, hire agreements, invoices, maintenance history and certification records.
- Conduct a controlled physical walkdown. Verify identity, location, status, configuration and observable condition without exceeding the authorised inspection scope.
- Reconcile the findings. Compare field evidence with operational, maintenance, procurement, hire, stores and financial records; record every discrepancy.
- Assess need, risk and options. Review utilisation, criticality, compliance status, lifecycle needs, supportability and commercial alternatives.
- Assign and close the disposition. Record the decision, technical and commercial basis, responsible owner, approval requirement, target date and closure evidence.
4. Asset identification and reconciliation
Every asset in scope should be physically verified. A photograph and identification-plate image can support the record, but neither replaces transcription and checking of the identifying data.
Identity and function
- Asset or tag number, description and equipment category
- Function, manufacturer, model and serial number
- Year of manufacture where available
- System, package or parent asset
Location and custody
- Physical location
- Responsible department and operational custodian
- Owner or hire supplier
- Ownership or hire status
Status and evidence
- Installed, mobile, temporary, standby, stored or redundant status
- Current operating condition
- Photograph and identification-plate evidence
- Source record and date verified
Record control
- Record owner
- Missing, conflicting or uncertain information
- Correction or escalation required
- Traceable verification reference
Reconcile the verified record against asset registers, CMMS, procurement records, purchase orders, hire contracts, supplier invoices, maintenance history, certification registers, stores records, project equipment lists, and transfer, disposal and off-hire records. Treat both directions as exceptions: equipment found but not recorded, and equipment recorded or invoiced but not found.
5. Hired-equipment assessment
Establish the complete technical and commercial position for every hired, rented or leased asset. The record should cover:
- supplier, contract and purchase-order references;
- original hire start date and continuous time on hire;
- original purpose and current requirement;
- hire rate, rate changes and minimum term;
- renewal, notice and off-hire provisions;
- mobilisation and demobilisation costs;
- fuel, consumable and service charges;
- damage, insurance, loss and return-condition provisions;
- maintenance responsibility;
- inspection, certification and statutory-examination responsibility;
- breakdown response and replacement entitlement;
- accumulated expenditure and forecast continued-hire cost;
- equivalent replacement or purchase cost;
- owned alternatives, sharing and redeployment options;
- continued-hire versus purchase break-even;
- idle or unjustified hire exposure;
- commercial owner and invoice approver.
6. Operating hours and utilisation
Record the current meter reading, meter type and unit, reading date, evidence source and previous readings. Where relevant, assess total hours, hours during the review period, start/stop cycles, loaded and unloaded operation, productive time, standby, idle time while on hire, planned and unplanned downtime, seasonal or campaign use, and actual demand against the original need.
Consider expected future demand, together with relevant fuel, energy or material consumption and cost per operating hour or productive use. Keep measured readings, system-derived data and estimates visibly separate. Where reliable meter history does not exist, state the limitation and use appropriately qualified conclusions rather than false precision.
7. Operational need and criticality
Define the process or operation supported and the present and future requirement. Assess the consequences of failure across safety, environment, production, schedule, regulation and contract; single-point-failure exposure; redundancy; alternative equipment; contingency arrangements; replacement response time; supplier lead time; and whether the equipment remains correctly sized for actual demand.
8. Condition and integrity
Record observable field condition consistently, including:
- damage, deterioration, corrosion or leakage;
- guards, enclosures and protective devices;
- structural condition;
- cables, hoses, piping and connections;
- instrumentation and indication;
- safety devices, trips, alarms and interlocks;
- emergency-stop provisions;
- labels and operating information;
- temporary repairs and unapproved modifications;
- environmental exposure, storage and preservation;
- apparent misuse or unsuitable duty;
- obsolescence and support availability;
- access for inspection and maintenance;
- known defects and restrictions;
- need for specialist assessment.
Observations should describe what was seen, the evidence reference and any immediate control required. They must not imply internal condition, remaining life or fitness for service beyond the competence and examination actually applied.
9. Maintenance and reliability
Review preventive-maintenance requirements and ownership; last and next service dates; meter-based intervals; overdue work; open work orders and backlog; breakdown and downtime history; repeated defects and failure patterns; repair response; temporary repairs still in service; warranty matters; OEM recommendations and relevant technical or safety notices.
Also establish spare-parts availability, critical spares, long-lead items, vendor support, manuals and drawings, maintenance-log accuracy, and the evidence supporting any return to service. A clean current appearance does not compensate for missing maintenance history or unresolved repeated failures.
10. Inspection, certification and compliance
Identify the applicable inspection regime, last and next inspection dates, outstanding findings, calibration, test certificates, lifting-equipment examination, pressure-equipment requirements, electrical inspection, conformity documentation, OEM manuals and declarations, risk assessments, operating procedures, operator competence or authorisation, environmental controls, and relevant Class, flag, client and regulatory requirements.
Confirm responsibility for renewal and compare certificate identity with the serial number and actual equipment configuration. Applicable duties depend on jurisdiction, equipment type, duty and contractual scope. A certificate that belongs to a different serial number or configuration is not evidence for the equipment found.
11. Configuration and documentation
Check current drawings, data sheets and manufacturer documents; installed accessories and attachments; software or firmware where relevant; approved modifications; temporary configurations; deviations and concessions; change-control records; interfaces with permanent systems; utilities and supporting services; and asset-to-document traceability.
Record superseded or conflicting information, open technical queries and restrictions on use. Uncertain identity, condition, certification or configuration requires controlled escalation—potentially restriction, specialist assessment or quarantine—rather than an assumed acceptable status.
12. Cost and value review
Assess the full cost of retention, not only the headline hire rate or purchase price. Relevant elements include hire or lease charges, maintenance, fuel and energy, consumables, operators, downtime, spares, inspection and certification, transport and relocation, storage and preservation, insurance and damage exposure, supplier call-outs, administration, replacement or purchase, removal and return.
Set those costs against operational value, risk exposure and the remaining project or operating duration. A lower-cost option is not better if it creates unacceptable availability, compliance or delivery risk; equally, criticality should not become an untested reason to continue an avoidable commercial exposure.
13. Required disposition
Every asset should receive a documented outcome, not simply a review status.
- Retain in service
- Retain as justified standby
- Repair and retain
- Overhaul or life-extend
- Replace
- Resize
- Redeploy
- Consolidate duplicated equipment
- Substitute with an owned asset
- Renegotiate the hire
- Purchase instead of continuing hire
- Off-hire and return
- Preserve or store
- Restrict use pending evidence
- Quarantine pending assessment
- Dispose of redundant owned equipment
- Escalate for specialist engineering review
Record the technical, operational, risk and commercial basis; required action; accountable owner; target date; approval requirement; and evidence that will demonstrate closure. Commercial approval and technical acceptance should remain distinguishable where different authorities own them.
14. Deliverables
The review should leave a controlled decision set that can be maintained after the walkdown:
- verified master asset register;
- hired-equipment register;
- physical-to-record reconciliation;
- ownership and location confirmation;
- hire-duration and cost analysis;
- operating-hours and utilisation review;
- condition observations;
- maintenance and certification status;
- criticality assessment;
- documentation and data-quality gaps;
- duplicate, redundant and unidentified-equipment list;
- idle-hire and commercial-exposure register;
- risk-ranked findings;
- recommended disposition for each asset;
- prioritised action plan;
- decision and approval record;
- management summary and supporting evidence;
- recommended ongoing review cycle.
15. Ongoing control
Assign a named operational owner to every asset and a named commercial owner to every hire. Maintain periodic physical verification, routine meter readings, hire-age and cost reviews, certification-expiry and maintenance-due monitoring, idle-equipment review and recurring confirmation of operational need.
Control additions, transfers and removals; retain formal off-hire evidence; confirm that supplier invoicing has stopped; reconcile operations, CMMS, procurement and finance; retain decision evidence; and submit exceptions and overdue actions to management review. The value of the initial review is lost if register correction and disposition close-out are not sustained.
Authoritative context
These official sources provide context for asset-management principles and, in Great Britain, work-equipment duties. They are external authorities, not Elvis-authored guidance. Access and status were checked on 31 August 2026.
ISO asset-management principles
ISO 55000:2024 — vocabulary, overview and principles describes lifecycle value and systematic asset management. ISO 55001:2024 sets asset-management-system requirements and frames the balance among performance, risk and expenditure. The standards themselves are paid publications; these links provide ISO’s public summaries.
Reliability and maintenance data
ISO 14224:2016, confirmed current by ISO in 2022, provides a basis for collecting and exchanging equipment, failure and maintenance data in petroleum, petrochemical and natural-gas operations. It does not provide the full commercial assessment used in this review.
HSE work-equipment guidance
HSE publishes official guidance on hire responsibilities, the PUWER framework, maintenance and inspection of work equipment. Application depends on the equipment, undertaking and jurisdiction.
Lifting equipment
Where lifting equipment or accessories are in scope, consult the HSE LOLER overview and the site’s curated lifting technical-library sources. Neither is a substitute for the applicable examination scheme or competent-person assessment.
