In 2012, a power company developed two high-head power stations in Hawkes Bay, named The Esk Project after the Esk Valley near the site. Maskell supplied the two penstocks in FRP/GRP Flowtite pipe for both the Rimu and Toronui stages of the project. This is the third hydropower scheme in New Zealand to utilise fibreglass pipe for the penstocks.Maskell was selected for this aspect of the project, as both Maskell and Flowtite have proven experience in the supply of fibreglass pipe for penstocks projects.

Flowtite pipe was chosen for a 25 bar dewatering line in the Newmont mine in Indonesia. Maskell also designed and fabricated a number of special flanges and items that were required to connect the FRP line to the existing line. Due to its location – the mine is a 30-minute seaplane flight from Bali – Maskell also provided remote installation advice and technical assistance.
