Peninsula Energy (ASX:PEN) said as a result of incorrect installation by the contractor, both agitators at the Lance project central processing plant in Wyoming failed and require replacement, according to a Thursday Australian bourse filing.

During routine commissioning and ramp-up activities, installation-related deficiencies were identified in the agitator assemblies in both precipitation tanks.

Both agitator units were removed from service, and replacement kits were ordered from the manufacturer. Delivery is expected within five weeks to seven weeks.
