Fort Lewis Remediation System with SCADA:

 Electrical Engineer of Record for an environmental remediation system  for Battelle Labs and the Army.  Responsibilities included complete  electrical power distribution and control system design. This PC based  pump & treat control system pumps water from an underground plume  contaminated with solvents. A fiber optic network connects the main  control house with the eight pump houses, each of which has local I/O  and a variable frequency drive that controls the flow rate with a  positive displacement pump. 

Large Aerospace Remediation System and Facility Power Design:

 Complete control system and facility power distribution design of pump  and treat remediation system similar to the one above for Fort Lewis.   Worked with Snohomish County PUD to specify transformer locations and  sizes.  The system is designed to be easily expandable by employing an  expandable fiber-optic network which connects the main facility to  outlying control stations. 

Graving Dock Power and Control System Design:

 Electrical Engineer of Record for a  graving dock to be built by General Construction Company at Port  Angeles, WA. Responsibilities include complete electrical power  distribution and control system design. This facility design consists of  a PLC controlled pump system that controls flooding and dewatering of  the graving dock and the main gate which is designed to be water  ballasted and locked into place in an open or closed position. Only  three-phase power and Remote I/O communications were taken to the gate  so that the amount of festoon-like cabling connecting the dock and gate  could be minimized. 

Design Review Boeing Charleston Overhead Cranes:

 Worked with Boeing representatives, structural/mechanical consultants  and the crane manufacturer and provided electrical design review  services for Boeing Charleston's overhead crane systems. Reviewed design  at various levels of completion stages and provided suggestions for  breaker coordination, power and controls drawings, PLC programming,  equipment usage and selection. 

Siload Motion Control System:

 Designed control system and provided all programming and startup  services for an automated storage system at Kenworth's Renton plant  using Red Lion operator interface and a new Allen Bradley PLC with  serial port cards. The serial cards send ASCII commands to control three  existing older two-axes Industrial Devices servo drive systems. ASCII  strings are generated and concatenated based on PLC logic. Reusing the  existing motion controller/drive units and motors helped Kenworth  decrease the cost of the project. 

Container Crane Consulting:

 Container crane engineering oversight included verification of load  calculations, control systems design and material selection review for  four container (ship to shore) cranes for Westports in the Straights of  Malacca. This project included travel to manufacturers facility in  Shanghai to assist the customer in evaluation of the construction  progress and installation practices. 

Portal Crane Study and Specifications:

 Performed  feasibility study to evaluate generator and shore power options for  five U. S. Coast Guard portal cranes. The study provided evaluation of  options for repowering the cranes and replacing one of the cranes  existing late 60s era Avtek motor-generator controls. Also wrote  commercial grade specifications for new AC and DC drive based control  systems.
