Marine-Enhanced Transformer Panel Radiators for ACWA Al Mourjan CCPP 01

TengQi Technology supplied a project-specific panel radiator solution for the ACWA Al Mourjan (Rabigh 2) CCPP 01 combined-cycle power plant in Saudi Arabia. Designed for main transformer cooling system support, the scope addressed the combined challenges of high temperature, salt-laden marine air, humidity and dust in the Red Sea coastal environment.

Project Overview

ACWA Al Mourjan (Rabigh 2) CCPP 01 is a gas-fired combined-cycle power plant project located in the Rabigh coastal area of Saudi Arabia. In this operating context, the main transformer cooling system requires radiator equipment that can be coordinated with thermal duties while considering long-term exposure to a demanding coastal atmosphere.

Jiangsu Tengqi Electric Power Technology Co., Ltd., operating under the TengQi Technology (TQT) brand, provided transformer panel radiators as supporting equipment for the project’s main transformer cooling system. The supply scope concerned radiator manufacturing, corrosion-protection configuration and project delivery coordination; it did not include complete transformers or power plant equipment.

Specified Radiator Configuration

The listed configuration reflects the project input data. Final dimensions, interfaces, pressure requirements, test items, installation conditions and supply boundaries remain subject to approved drawings, technical agreements and order documents.

Red Sea Coastal Operating Considerations

The Red Sea coastal climate presents a complex exposure profile for oil-immersed transformer radiators. A suitable solution needs to account for thermal requirements as well as the interaction of marine corrosion, elevated ambient temperature and airborne dust over the service period.

• Salt mist and chloride exposure: Marine air can accelerate corrosion where moisture and chlorides reach the metal substrate. Welds, edges, corners and complex structural areas require focused coating coverage and surface-protection control.
• High ambient temperatures: Elevated temperatures increase the thermal management demands placed on transformer cooling systems. Radiator selection should be coordinated with transformer load, cooling mode, fan arrangement and required operating margin.
• Dust and salt-dust interaction: Coastal dust may contribute to surface contamination and maintenance requirements. Radiator structure, protective finish, transportation protection and site handling should all be considered as part of the project execution process.
• Overseas project coordination: EPC and power plant projects commonly require alignment on technical documentation, product identification, packing, inspection records and equipment interfaces before shipment and site installation.

Solution Focus for the Al Mourjan CCPP 01 Project

C5-M Marine Corrosion Protection

The PC3600-28/520 panel radiators were configured with a RAL7035 paint coating system and a total coating thickness of 260 μm for the project’s C5-M marine corrosion-protection direction. This approach is intended to provide enhanced resistance against moisture, salt mist and chloride-related corrosion risks associated with the Red Sea coastal environment. Effective corrosion protection also depends on surface preparation, coating continuity, treatment of welds and edges, shipping protection, installation practices and the acceptance requirements defined in project documentation.

Thermal-Area Configuration for Main Transformer Cooling

The radiator configuration includes both natural cooling area and forced-air cooling area to support project-specific main transformer cooling requirements. Selection is based on coordination with relevant operating inputs, including transformer thermal load, ambient temperature, cooling arrangement and operational margin. The 66.65 m² natural cooling area and 78.26 m² forced-air cooling area per set provide the stated configuration basis for this supply.

Adaptation to Salt and Dust Exposure

For a coastal power plant where salt mist and dust may coexist, the radiator solution considered structural design, protective coating and manufacturing-delivery controls intended to reduce the risk of pollutant accumulation and corrosive-media ingress. Actual cleaning intervals, contamination levels and field operating performance depend on site exposure intensity, installation location, maintenance practices and operating conditions.

Project Documentation and Delivery Coordination

TengQi Technology supported the project through technical communication, product selection, manufacturing, quality verification, English documentation preparation, export packing and delivery coordination. Cooling-system control signals, monitoring signals and DCS interface requirements are subject to the equipment supply boundary, control-system configuration and final project technical agreement.

Implementation Priorities

1. Corrosion classification and coating confirmation: Coastal distance, salt concentration, humidity, equipment layout, dust exposure and owner specifications should be reviewed when confirming the corrosion-protection system and associated quality controls.
2. Thermal design coordination: Radiator capacity should be matched with transformer capacity, cooling method, fan configuration, ambient conditions and duty requirements of the main transformer cooling system.
3. Sea freight packing and site protection: Long-distance marine transport and coastal storage require consideration of humidity, salt exposure, impact protection and the prevention of coating damage. Site storage, lifting, installation and local touch-up requirements should be addressed in relevant quality and site-management procedures.
4. Technical file and interface management: English drawings, inspection records, marking, packing documents and interface information should be prepared in accordance with the applicable contract and technical specification to support clear project coordination.
