RFI: online vibration monitoring system for oil-filled hv reactors – design, supply, installation & commissioning

Submit the following returnable documents with your bid: OEM user manual. Note: The SCOT Care Group will evaluate the document and its relevance every five (5) years or when deemed necessary.

OEM user manual must be submitted with the bid.

Scope: Design, manufacture, testing, supply, delivery (including training and spares), installation, and commissioning of an online vibration monitoring system for oil-filled HV reactors. Purpose: Continuous, real-time monitoring of reactor vibrations, including trending and alarming, to supplement periodic vibration tests and enable predictive maintenance.

Functional Requirements:

• Continuously measure and record vibration data from sensors mounted on the reactor main tank under all operating conditions, with correct timestamping. Display vibration data per sensor.
• Permanently store recorded data locally and transmit it to a portable engineering laptop or other local display. Include a modelled live display functionality.
• Provide web access to vibration data.
• Generate validated warnings with push SMS notifications when vibration levels exceed user-configurable thresholds.
• Comply with applicable cybersecurity requirements (e.g., IEC 62443).
• Include self-diagnostics for sensor and cable integrity.

Measurement Capability:

• Measure vibration displacement amplitudes up to at least 500 μm peak-to-peak (p-p).

Power Supply:

• Powered by easily available sources, preferably long-lasting built-in batteries or AC supply.

Packaging and Storage:

• Securely packed and protected against damage, moisture, and dirt during shipping and storage. All ports must be suitably sealed.

Installation:

• Transducers or equivalent measuring devices must be mountable on reactor tank side walls and remain attached under severe vibrations.
• Training must be provided to responsible engineering personnel during installation, covering installation, commissioning, operation, maintenance, and decommissioning.

Environmental Conditions:

• Outdoor installation at altitudes up to 1800 m above sea level.
• Ambient temperatures: max +40°C, monthly average +28°C, yearly average +25°C, minimum -10°C.
• Average relative humidity: 90%.
• Solar radiation: 2500 kWh/m².
• High atmospheric UV radiation.
• Seismic conditions: minimum 0.3g.
• Pollution level: High marine and industrial (C5).

General Requirements:

• Design lifespan: at least 40 years (matching reactor service life) when used and maintained per OEM manual.
• All components must be housed in IP65-rated enclosures.
• Must not impede or compromise reactor safety or personnel safety.

Standards Compliance:

• ISO 9001 (Quality Management Systems).
• IEC 60076-6 (Reactors).
• IEC 60529 (IP Code).
• IEC 62443 (Industrial communication networks – Network and system security).
• IEC 61850 (Communication networks and systems for power utility automation).
• IEC 61010 (Safety requirements for electrical equipment for measurement, control, and laboratory use).

Compliance with ISO 9001 (Quality Management Systems) is required. The system must adhere to NTCSA specification 240-60725684 (Specification for oil-immersed HV and EHV Power Reactors) and IEC 60076-6 (Reactors).

Quality Management: Compliance with ISO 9001 (Quality Management Systems) is required.

Cybersecurity: The system and its components must comply with applicable cybersecurity requirements (e.g., IEC 62443) to protect data integrity, confidentiality, and availability.

Safety: Compliance with IEC 61010 (Safety requirements for electrical equipment for measurement, control, and laboratory use) is required.

Enclosure Rating: All components must be housed in IP65-rated enclosures as per IEC 60529.

Reactor Standards: Compliance with IEC 60076-6 (Reactors) and NTCSA specification 240-60725684 (Specification for oil-immersed HV and EHV Power Reactors).

The system must comply with IEC 61010 (Safety requirements for electrical equipment for measurement, control, and laboratory use). It must not impede or compromise the safe operation of the reactor or the safety of personnel in the vicinity.

The system must have a design lifespan of at least 40 years, matching the expected reactor service life, when used and maintained per the OEM manual. All components must be housed in IP65-rated enclosures. The system must not impede or compromise the safe operation of the reactor or the safety of personnel in the vicinity.

The supplier must provide on-going technical and maintenance support to ensure reliable system performance, preferably throughout its service life but at least for five (5) years after first commissioning.

NTCSA will evaluate proposals as per the provided technical evaluation criteria. Further negotiations and award will be conducted with top-ranking proposals, as calculated from the submissions using the scoring criteria. Proposals most aligned with NTCSA requirements will be prioritized.
