Key West Naval Air Station

May 21th, 2020

Prepared by Daniel Gibbens (email me)

Project:  API 653 Repairs – Tank 944

General Contractor: Goshawk

Customer: NAVFAC

 

Scope:  All surface preparation and coatings for the tank exterior and interior of Tank 944 (45’ x 19’) at Naval Air Station Key West, FL.  (2019)

 

Total SF (interior & exteriors): 10,548

 

Champion deployed a five-man crew 185 miles from our Southeast region office in Fort Lauderdale, FL.  Work began on August 7, 2019 and finished on October 5, 2019.  Due to the specified coatings systems, extreme summer heat, high humidity, proximity to the ocean, and near-daily precipitation, this tank required full scaffolding, shrink-wrap containment, dehumidification, and temperature control with 24 hour monitoring.

 

Exterior access was facilitated with a full scaffold system.  Interiors were accessed with rolling scaffolds.  Champion completed surface preparation with dry abrasive blast as requested by the GC.  Even with a U.S.G. mandated shutdown to prepare for Hurricane Dorian (conducted in accordance with DoD HURCON procedures), the project was completed on time and budget.  Additionally, SSPC conducted periodic QP-1 and QS-1 audits on Champion during the project IAW certification requirements, both of which the company successfully passed.
