FOR Geophysical survey firms, exploration managers and seismic subcontractors
Field acquisition and interpretation are different services
A seismic contractor may acquire raw measurements, process information, interpret subsurface features, or combine these services. Its insurance description should identify each activity and the entity performing it. A field crew that follows a client-designed survey has different responsibilities from a consultant selecting survey parameters and delivering an interpretation used for an investment decision.
Document whether the campaign is land based, marine, airborne or mixed. Identify subcontracted vessels, aircraft, explosives specialists and land-access services separately. BOEM’s published geological and geophysical information describes its offshore permitting role; that framework should not be treated as the rule for every onshore survey or as evidence that a particular contractor is authorized.
Access losses can outlast the field campaign
Consider a survey vehicle damaging a private road, a source operation allegedly affecting a nearby structure, or a crew leaving drainage damage that becomes evident after heavy rain. These are different from a client alleging that defective processing produced an unusable dataset. Review general liability, automobile, contractors equipment and professional liability against those separate allegations.
Access agreements may promise restoration beyond the contractor’s ordinary legal liability. Examine assumptions of liability, damage-to-property limitations, vibration or blasting restrictions, and the treatment of subcontracted operations. A client’s approval of a route does not establish that damage is insured, and an access bond is not interchangeable with liability insurance.
Protect equipment and the value of acquired data
Survey instruments can be dispersed across a wide area, left unattended or carried between temporary storage points. Schedule owned and hired units with realistic replacement values, territorial limits and theft controls. Discuss recovery expenses when equipment is inaccessible, rather than assuming an equipment limit includes every search or retrieval cost.
Raw data may be expensive to recreate even when the recording hardware is inexpensive. Ask how duplicate copies, corrupted files, accidental deletion and the cost of repeating acquisition would be addressed. Distinguish physical equipment damage from an error in processing or a contractual obligation to deliver a particular result. Document backup custody and client acceptance procedures before mobilization.
Make the submission match the contract deliverables
Provide sample contracts, survey methods, crew size, equipment schedules and a clear list of excluded services. Explain who verifies access rights, coordinates landowners, approves source locations and signs off the final data. Include quality-control procedures, documented escalation of anomalies and records showing when the client accepted each deliverable.
For a joint field operation, identify the party responsible for incident notification and preserving raw records. Professional claims may arrive after the crew has moved to another assignment, so review reporting requirements and continuity when changing insurers or closing a project entity. The insurance discussion should address both a damaged location and a disputed deliverable without presenting either outcome as automatically covered.
Operational exposures & coverage review
These review points are educational interpretation, not promises of insurance coverage.
| Exposure | Insurance review |
|---|---|
| Survey method | Disclose vibration sources, explosives, vessels or aircraft. |
| Data reliance | Separate acquisition errors from interpretation obligations. |
| Dispersed equipment | Review unattended property, transit and retrieval terms. |
Questions for your next review
- Who owns and backs up the raw data?
- Which access promises exceed ordinary damage liability?
- Are marine or airborne activities specifically disclosed?
