Mechanical parts on engineering drawings for RFQ evidence review

RFQ evidence guide for marine engine-room spare parts supply

You do not always need a perfect part number to start an engine-room spare parts supply request. Send the evidence you have and Vessel Core can structure the RFQ for supply route review.

Evidence for engine-room spare parts supply review

  • Equipment maker: MAN B&W, Wärtsilä, Caterpillar, Alfa Laval, ABB, Yanmar or another maker if known.
  • Model or type: engine model, pump type, detector model, gauge range, sensor type or panel reference.
  • Serial number: equipment serial number, tag number or plate data when available.
  • Part reference: part number, drawing number, old quote reference, old part marking or part-book page.
  • Photos: nameplate, failed part, old part, installation position, damaged component or packing label.
  • Quantity: pieces, sets, kits, service interval quantity or emergency minimum.
  • Timing: port, ETA, docking window, urgency and documentation needs.
  • Route preference: OEM required, verified alternative acceptable or route review requested.
Pumps

Nameplate and duty first.

  • pump maker, type, model and serial number;
  • nameplate photo and installation context;
  • duty, fluid, flow/head if available;
  • seal, bearing, impeller, casing or shaft reference;
  • old part references, drawings or service notes.
Gas detectors

Sensor range and calibration context.

  • maker, model and fixed or portable detector context;
  • gas type and sensor range;
  • calibration certificate or last calibration context if available;
  • sensor module, transmitter, display or alarm panel reference;
  • approval or documentation needs if required onboard.
Thermometers / gauges

Range, connection and accuracy.

  • temperature or pressure range;
  • connection size, thread, stem length or mounting style;
  • accuracy class and calibration requirement;
  • dial size, material and system context;
  • photo of old unit, scale and connection.
Sensors

Signal and process data prevent mismatch.

  • sensor type: pressure, temperature, level, flow, proximity or another type;
  • range, output signal and supply voltage;
  • connector, cable, plug or pin details;
  • process medium, mounting point and system context;
  • maker, model, serial or tag number from the existing sensor.

OEM vs verified alternative route

Some engine-room spare parts RFQs require OEM supply or specific documentation. Other requests may allow verified alternative routes. Vessel Core can separate these routes at RFQ stage so supply review is clearer.

Alternative route review does not mean a part is automatically suitable. Technical evidence, documentation needs and buyer approval requirements must be confirmed before quotation or order.

Attachments guidance

The website form does not upload files in this phase. Send the RFQ first, then reply to the confirmation email with photos, nameplates, drawings or part-book pages. You can also use your email client directly.
