Personal Background

1993 to 1997

Serving Electro Technical Officer then 2nd Marine Engineer Officer on a variety of Merchant Navy vessels before spending 1997 working in the North Sea on Dynamically positioned semi submersibles involved in sub sea construction in the oil and gas industry 

1998 to 2006

Field Service Engineer with  Brush Electrical Machines.  

Commissioned around  2,500 Mw of power generation consisting mainly of LM6000 driven machines and TM2500’s

Assignments were worldwide and various including commissioning the main power generation on the Queen Mary 2 ( 2 LM2500 plus driven turbo alternators controlled by PRISMIC A30M Excitation controllers) .

Final project with Brush was commisioning a PRISMIC Power management system in Saudia Arabia. The PMS was located on a large LNG facility at Yanbu and controlled  a split 115Kv bus feeding two 115/13.8Kv On line tap changer transformers, each tap changer having two 13.8Kv secondaries load control of 3 GE frame 6 turbines (90Mw total) using MKVI millennium turbine control and the EX2000 excitation control. Management of all load shedding, synchronising to the grid, synchronising between buses (around 20 different permutations).
