Sava Medonos - Principal Engineer/Director

This website is about Sava MEDONOS – an individual who specialises in Risk Assessment, Loss Prevention, Safety Engineering and Technical Management in the oil and gas industry offshore and onshore, including shale gas. Sava is known in the industry as an innovator and international expert; he has achieved multi-million pound savings for several operating companies.

Sava has a Master of Science Degree in Mechanical Engineering and 30+ years of experience in risk assessment, loss prevention and safety engineering in the oil and gas industry, both offshore and onshore, including shale gas, 12 years of which were in the employment of a major Certifying and Verification Authority.

Throughout his career Sava has worked on projects for over 70 design and operating companies on their facilities in 26 countries. The facilities he has worked on are piled and gravity-based offshore platforms, floating production and storage offshore facilities, drilling rigs, refineries, gas plants, oil and gas terminals and pipelines.

Sava’s strength in providing low-cost solutions in technical safety is based on his combined experience in:

  • multi-discipline and multi-system approach in combination with risk, facility integrity, resilience and response, and response of facility personnel;
  • the implementation of findings of risk assessments on the facilities;
  • participation in research and development, and the implementation of resulting solutions in practical facility operations;
  • in-situ testing of safety critical elements and systems; and
  • accident investigations;
  • all in conjunction with his work in Risk Assessment, Loss Prevention, Safety Engineering and Technical Management.

The best possible use of Sava’s services in the current cost-cutting environment in the oil and gas industry is the provision of assistance to Chief Engineers, Project Managers, Discipline Managers and Technical Directors. This is because, based on his past experience, he knows low-costs safety solutions that work, without performing complex analyses.

Sava has obtained the permission to say that he and his team has worked for Maersk Oil and Gas for over fifteen years. Maersk operates most of the oil and gas facilities in the Danish Sector of the North Sea.

He covers all disciplines required in these areas and provides these services through Petrellus Engineering Ltd. His multi-discipline skills may be further augmented by his team of senior specialists should that be required.

Description of Services on Offer

As an individual Sava provides services in Risk Assessment , Loss Prevention , Safety Engineering and Technical Management .

Risk Assessment covers all aspects of qualitative and quantitative assessments of technical risks from the facilitations of HAZOPs and hazard identification (HAZIDs and ALARP) studies, carrying out frequency analysis, consequence analysis, response analysis, risk evaluation and the preparation of technical reports for the submission to the Regulatory Bodies and Certifying Authorities.

Loss Prevention typically covers the reviews and design of harmonised responses of facilities and personnel, site surveys and witnessing of testing of Safety Critical Elements, and facilitations of Loss Prevention Review Workshops.

Safety Engineering typically involves the analysis and design of resistance of offshore and onshore facilities to accidental and seismic loads, fire and explosion protection optimisation and fire and gas detection mapping.

Technical Management service area involves peer reviews, independent verification and risk management throughout the whole life cycle of a facility. Throughout his career Sava has held senior management positions of Consultancy Manager, Divisional Director and Managing Director. He developed businesses and managed them. These skills apply to a much wider range of industries than oil and gas. They are offered in the form of Sava working as a part–time, non–executive director.

Finally, Sava has also been involved in the development of International Standards and Guidance and Training Seminars where he contributed to the development and dissemination of technology and methods.

There are several disciplines within each service area, the details of which may be found in the Services page.

Facilities resist and respond to accidents in a multi-system and multi-discipline manner and mobilising residual strength beyond first yield. Sava uses a multi–system, multi–discipline, risk- and integrity based approach, unless the Client prefers a different method. Coming from one person (himself) has the advantage that the interfaces between systems, disciplines, risk and integrity are fully included and utilised, which is often lost when several personnel are involved individually.
