NASSCO - Multiple Projects

Project Overview

Michael Wall Engineering has designed over 15 projects for NASSCO and has been the providing engineering services at the Harbor Drive plant for over a decade.  NASSCO constructs and repairs commercial and military vessels for a number of international clients, ranging from small cruisers to oil tankers.  Our design work has included an extensive range of industrial electrical systems including a new 2000A 12kV electrical service that supplies (6) 3000kVA unit substations at the paint shop.  Specification of 12kV sectionalizing SF6 gas switches were designed into the 12kV distribution system, allowing NASSCO to perform easy maintenance while eliminating plant outages.  All electrical systems are  designed for the hostile industrial marine environment and provide high reliability and extremely rugged construction.  Specialized engineering designs were provided for welding tables, dry docks, pin jigs, slipways, blasting cells, and paint booths.  Engineering consulting was provided for short circuit and coordination studies, 12kV service entrance replacements, substation replacements, power factor correction, and pier expansion.
