Jirau Hydroelectric Power Plant, Porto Velho, Rondônia, Brazil

Maximum performance with standard modular product
With 5,957 m length and 56 m height, Jirau will become the world's 14th largest power station regarding its capacity for sustainable energy production in the world.

Description

This project is a clear example of environmental sustainability. With 5,957 m length and 56 m height, Jirau will become the world's 14th largest power station regarding its capacity for sustainable energy production in the world: 3,750 MW.

Despite its complexity, all project needs were covered with ULMA's MK System.

With standard parts only, it offers the best solution for high load requirements. Moreover, this system provides a 50% productivity increase compared to conventional systems. 

    • Equipment: 1,000 t
    • Power production: 3,750 MW
    • Concrete volume: 2,478,361 m3
    • Turbines: 50
    • At peak production: 18,000 employees

ULMA Solution

As ULMA, we guarantee maximum performance with our innovative products and structures made up of standard modular material.

To cope with the dimensions of the water intakes (18 m high and 2.5 m thick), a solution with two mobile MK-360 Shoring towers and ENKOFORM HMK and VMK formwork was designed. Erection and dismantling tasks were considerably quicker with a form carrier with rolling system moved forward from stage to stage.

Despite the complex shape of the Transition Tunnel (27 m long with a height between 11 and 14.5 m), the stretches were built with the MK System in a sequential manner.

Workers' safety is our highest priority. Hence, MK Structure was equipped with perimeter protection and formwork support.
