Developed the UKAS accredited requirements management system to support the development of competencies and authorisations to confirm that an engineer has the appropriate skills to carry out Type Certification of a client’s wind turbine to IEC 61400-22 and the other standards in the IEC 61400 range to comply with ISO 17065.Supported the Technology Qualification of the AW Energy .Oy waveroller, a device designed to generate energy from the waves.Is a member of the IEC Renewable… Show more Developed the UKAS accredited requirements management system to support the development of competencies and authorisations to confirm that an engineer has the appropriate skills to carry out Type Certification of a client’s wind turbine to IEC 61400-22 and the other standards in the IEC 61400 range to comply with ISO 17065.Supported the Technology Qualification of the AW Energy .Oy waveroller, a device designed to generate energy from the waves.Is a member of the IEC Renewable Energy committee charged with developing the Rules of Procedure for how a certification body or test lab should become and remain accredited to assess Wind Energy components.Developing renewable consultancy and conformity services, particularly development of a WTG controller that takes advantage of a number of novel ideas and some standard linearisation, transfer function, state space, SISO, SIMO and frequency domain techniques. The controller is developed using MATLAB, Simulink and NREL's FAST.I introduced the team to Team Foundation Server to manage changes that the team made to FAST, programmed in Fortran 90. Show less

Built and ran a team to take a controller from GL Garrad Hassan to develop and improve it to increase company intellectual value, reduce the cost of machine through load reduction and increase customer returns by increasing energy yield.Work with the loads team analysts to understand and improve machine response to deterministic and stochastic wind and machine events. Used Bladed to investigate the effect that changes to the controller had on the system.Develop systems to manage… Show more Built and ran a team to take a controller from GL Garrad Hassan to develop and improve it to increase company intellectual value, reduce the cost of machine through load reduction and increase customer returns by increasing energy yield.Work with the loads team analysts to understand and improve machine response to deterministic and stochastic wind and machine events. Used Bladed to investigate the effect that changes to the controller had on the system.Develop systems to manage turbine software development and change management. (Subversion and Jira)Apply a holistic understanding of the machine to investigate faults and drive reliability improvements.Follow GL2010 guidelines and apply Machine safety regulations ISO 12000. Create processes to assist engineers to carry out FMEAs to BS EN 60812 to identify required safety performance level (PLr) for different system and show that the design achieves this level (PLa) according to ISO 13849 as a means of ensuring a safe, reliable machine design is achieved. Program safety related sections of the controller in a manner that is compliant with BS EN 61508 (Functional safety of electrical/electronic/programmable electronic safety-related systems, Part 3: Software requirements).Develop systems to test that implemented machine behaviour is as expected and simulated and to prove build quality of each machine.I left as the company went into receivership.

Tewkesbury

Designed closed loop controllers for the world's largest linear friction welding machine (2008), aircraft carrier engine starter pack and helped with Wimbledon stadium roof. The controllers were programmed in IEC 61131. Controlled systems were programmed to move in a 'bumpless' fashion between position/load or torque/power/speed. The control loops for Thompson's friction welder were able to exceed the client's tolerance specification through a solid understanding of the physics involved in… Show more Designed closed loop controllers for the world's largest linear friction welding machine (2008), aircraft carrier engine starter pack and helped with Wimbledon stadium roof. The controllers were programmed in IEC 61131. Controlled systems were programmed to move in a 'bumpless' fashion between position/load or torque/power/speed. The control loops for Thompson's friction welder were able to exceed the client's tolerance specification through a solid understanding of the physics involved in the welding process. The engine starter pack controller, hydraulic power pack, closed loop hydraulic system and engine were modelled in Simulink.I programmed Labview applications to support the production testing of valves for the Formula 1 industry.I left to relocate to support a new role my wife took up in Yeovil.

Led a small team of engineers to provide test equipment for the qualification (environmental, fatigue, endurance and performance) and acceptance (production) testing for the electro-mechanical uplocks, selector valves and bogie pitch trimmer for the landing gear system of the Airbus A380 and the hydro-mechanical uplocks, selector valves and nose wheel steering manifold of the Boeing 787.Test rigs were typically a combination of mechanical fixture, hydraulic load application… Show more Led a small team of engineers to provide test equipment for the qualification (environmental, fatigue, endurance and performance) and acceptance (production) testing for the electro-mechanical uplocks, selector valves and bogie pitch trimmer for the landing gear system of the Airbus A380 and the hydro-mechanical uplocks, selector valves and nose wheel steering manifold of the Boeing 787.Test rigs were typically a combination of mechanical fixture, hydraulic load application, instrumentation and SCADA programmed using LabView and PLCs programmed in IEC 61131-3.During this time I was able to manage the design, manufacture, commissioning and provide support for the running of approximately 20 test rigs.I left shortly after GE announced that they were going to close the plant at Arle Court.

Yeovil

Development of a set of models to simulate the behavior of the entire Nimrod 2000 hydraulic system using Flowmaster 2.0 and MathCad.I left after being placed on the At Risk Register during a round of redundancies and finding a more attractive role elsewhere.

Yeovil

Responsible for writing qualification and acceptance test procedures in line with MIL-STD 810. I then built test fixtures, carried out the testing and wrote the reports.
