Surface Preparation, Blasting & Painting Project

Power Infrastructure Refurbishment through Industrial Surface Engineering

EDM Mavuzi Power Plant – Surface Preparation, Blasting & Painting

Industrial Surface Protection & Engineering Restoration for Critical Power Infrastructure

The Mavuzi Power Station, operated by Electricidade de Moçambique (EDM), is one of the oldest hydroelectric power plants in Mozambique. As part of a major refurbishment initiative to enhance performance and extend the lifespan of the facility, SIROCCOI (U) Ltd was contracted to perform specialized blasting and industrial painting services for key components of the power generation infrastructure.

This project demonstrated our capability to work on critical energy infrastructure in complex environments, ensuring long-term corrosion protection and improved operational efficiency.

Power Infrastructure Refurbishment through Industrial Surface Engineering

The ZESCO Kariba North Power Plant is one of the largest hydropower stations in Southern Africa, supplying vital energy to Zambia and surrounding regions.

Scope of Work

The project involved mechanical surface restoration and application of protective coatings to core power plant structures. Key tasks included:

High-pressure abrasive blasting to remove scale, old coatings, and corrosion inside and outside steel penstocks.
Surface preparation and painting of large-diameter drainage pipes within the facility to prevent rust and wear.
Use of industrial-grade epoxy and polyurethane coating systems, applied using airless spray techniques for uniformity and adhesion
Specialized work in narrow and enclosed areas using trained teams equipped with ventilation and safety systems.
Use of Elcometer tools to verify coating thickness, adhesion, and surface profile for compliance with international standards.

Challenges & Solutions

Challenge 1: Aged Infrastructure with Surface Degradation
Due to age and exposure, many steel components exhibited extensive corrosion. SIROCCOI deployed enhanced surface preparation techniques to achieve a near-white metal finish suitable for high-performance coatings.

Challenge 2: Remote Site Logistics
Located in a mountainous area with access limitations, the Mavuzi plant required detailed logistical planning. Equipment and personnel were mobilized swiftly, and operations were executed on schedule.

Challenge 3: Safety in Confined Spaces
Working in enclosed, pressurized systems posed safety risks. We implemented confined space entry protocols, constant monitoring, and PPE compliance to ensure zero incidents.

Results/(Project Outcomes)

Full refurbishment of internal and external penstock surfaces
of durable coatings ensuring 10+ years of corrosion resistance
safety incidents reported
with all EDM technical standards and inspection benchmarks
delivery with no safety incidents or delays
