Five dead in penstock fire at Cabin Creek PS plant

Nine workers were 1500ft-2000ft (457m-609m) underground and applying an epoxy coating to the inside of the penstock for corrosion protection when the fire started around 14:00hrs local time.Four of the nine were working below the elevation of the fire and managed to escape while the five working above climbed higher,to some 1000ft (just over First Energy Penstock Painting Alpine PaintingThis plant has been in operation since 1964 when the penstock was built.The original lead coating was removed from the exterior in 1985 and an Inorganic Zinc/Chlorinated Rubber system was installed.The coating system has performed well over the last 23 years,but was beginning to show signs of corrosion and was due for maintenance.Dry Ice Blasting HRSG Cleaning,Surface Preparation penstock was 250 feet by 16 feet in diameter and the stacks were each 40 feet high and five feet in diameter.Being able to complete all aspects job was essential,the scope of work was quite comprehensive.Before any s ace preparation and coating applicatiop could take place,a scaffold had to be conSttucted around the pre coating penstock#232;enstock and its two

Coating maintenance optimization for steel penstocks - UBC

Two methods for minimizing coating maintenance costs for steel penstocks are presented in this thesis.The first method performs a life-cycle cost analysis using equivalent annual costs to compare the three maintenance strategies touch-up,overcoat,and,strip and recoat.The strategy with the lowest annual costs is considered to be optimal.The second method uses a dynamic programming Carbon fiber reinforcement of the penstockMasterBrace PRE MasterBrace FIB 300/50 CFS MasterBrace SAT 4500 MasterBrace ADH 4000 Carbon fiber reinforcement of the penstock Contact BASF Construction Chemicals Italia,Spa.Via Vicinale delle Corti,21 31100 Treviso (TV) - Italy Tel +39 0422 429200 Fax +39 0422 421802 Reinforced penstock at EDF La Coche (Le Bois France)Bureau of Reclamation Research and Development using more environmentally friendly coating systems.Cathodic protection can be used in conjunction with coatings,and when applied correctly,will extend the service life of the coating.Below are some of the key questions for this study What are the lifecyle costs of Reclamation's corrosion control systems for penstocks and gates?
