Qualifications

BEng Parts I & II Engineering Science and Industrial Management

IOSH Managing Safety Certificate.

Background

36 years worldwide acquisition experience. 

8 years as an observer, senior observer and party chief with geophysical contractor. Operating as an acquisition consultant since 1991, wide experience of seismic and navigation quality control and data processing. Also has training and experience in project planning and management.

 

Personal Statement

I take great pride in my work and enjoy the opportunity to make a difference. Difficult surveys hold the most interest as I enjoy problem solving and such projects offer some of the best opportunities for me to make a significant contribution.

 

New and emerging technologies are of keen interest as they present both a challenge and an opportunity to learn. They help me to stay relevant and often provide an opportunity to mix ideas with field leading experts.

 

Inexperienced clients and contractors also offer a great opportunity to make contributions that are not only gratifying but also of great financial value to the project. Using my experience, I can assist such clients and contractors improve their practical knowledge and experience as well as achieving successful projects while minimising costs.

 

The HSE aspect of the role holds special interest. I have a keen and personal interest in seeing improvements being made. I strive to encourage continuous progress in practical aspects of working practices.
