Repairs on gas turbine three (GT-3) of Oman’s Barka Two power and water desalisanation plant have finished ahead of schedule, roughly three weeks after an inspection initially revealed damage.

In an 11 April, 2019, filing to the Muscat Securities Market, plant operator SMN Power Holding said the affected unit returned to service on 4 April – six calendar days ahead of its previously communicated expected completion date.

The financial impact due to the outage and repair work amounted to $1.8m (OMR800,000), the group added.

The Barka 2 water desalination plant uses reverse osmosis technology to deliver 120,000m3 of potable water per day to Oman Water Transmission System. Its three gas- and two steam-powered turbines deliver 678-megawatt of electricity to Oman.

The repair update comes two weeks after a similar SMN bourse missive, which indicated a borescopic inspection of GT-3 on 18 March had revealed damage to its turbine blades.

At the time, SMN said the repair’s estimated financial impact stood at $2m, slightly higher than the actual repair figure.

This is not the first time an Oman-based power company has promptly resolved technical issues. November 2018 saw a technical fault afflict the second gas turbine, known as GT-1, at Acwa Power’s Barka plant due to a “fault in [the] electricity generator unit”.

Both gas turbines were shut as a result, with the plant’s steam turbine generator out of action following the incident.

Repair activities on GT-1 were supported by Italian power engineering company Ansaldo Energia, with the plant returning to normal operations in January 2019.
