The terminology.
Without the guesswork.

Automatic Identification System. See the linked U.S. Coast Guard reference for equipment and identity guidance.

Annual performance test. In a VDR inquiry, distinguish the test and issuer route from an ordinary repair attendance.

Bridge Navigational Watch Alarm System. Identify the exact model and fault; this site provides no bypass instructions.

The vessel’s classification society in the relevant service context. Identify the actual society and required scope; a logo is not approval evidence.

The assembled record of the agreed work, results, documents, limitations, and unresolved actions.

Certificate of compliance in the relevant job context. The exact document and authorized issuer must be confirmed.

An agreed method for sharing documents or access details with appropriate authorization and access restrictions.

The controlled document or responsible authority that supports a date entered in a planning record.

Electronic Chart Display and Information System. A safety-relevant system; see the IMO reference.

Electronic Navigational Chart. Chart supply and software support are distinct parts of an ECDIS inquiry.

Emergency Position-Indicating Radio Beacon. Do not activate or open one to prepare a service inquiry.

Estimated time of arrival. Include the date and UTC offset and identify whether the estimate is provisional.

Estimated time of departure. A key inquiry constraint, not a guaranteed work window.

An item supplied under an exchange arrangement. Return conditions, compatibility, and commercial terms require confirmation.

The vessel’s flag administration for the relevant regulatory context. State it for approval or certificate inquiries.

A controlled inventory of equipment identities, service references, known dates, and open items.

Global Maritime Distress and Safety System. See IMO’s radiocommunications overview.

A vessel identifier where applicable. Use the number from the vessel’s records rather than guessing.

The entity responsible for issuing the specified final document; it is identified in the agreed scope.

The equipment models actually covered by a competence or authorization record.

Original equipment manufacturer. Manufacturer authorization applies to a defined organization, equipment range and service scope.

An unresolved action, fault, dependency, or documentation requirement with a stated owner.

Purchase order. A saved inquiry or RFQ does not itself authorize a purchase.

An inquiry priority describing a time constraint. It does not promise emergency attendance.

Request for quotation. A structured request for scope, availability, price, and terms—not an order.

Return material authorization or equivalent supplier process. Obtain instructions before shipping an item for review.

Search and Rescue Transponder in the applicable equipment context. Identify the actual model and requested task.

Satellite communications. Identify the affected terminal, service, and provider responsibilities.

The agreed task, equipment, deliverables, assumptions, exclusions, and approval requirements.

Time reserved or spent awaiting readiness under an agreed commercial arrangement. Charges require contractual definition.

Simplified Voyage Data Recorder. Model and task-specific authority remain relevant to service requests.

The stated difference between local time and UTC. Include it with arrival, departure, and preferred attendance times.

Voyage Data Recorder. Recording, repair, data handling, and annual testing are separate scope questions.

An explicit confirmation of a defined scope or attendance. An inquiry submission alone is not acceptance.
