On average, oil and gas companies, and water/wastewater industries, use six per cent of their annual income to combat corrosion.

This book has been prepared to satisfy the needs of students, practising engineers and scientists for an introduction to the corrosion protection for the oil and gas industry, and overcome corrosion issues. The author have made the book very concise and easily understood.  This book covers the subject of corrosion protection for the oil and gas industry. It is concerned primarily with the external and internal corrosion protection of onshore pipelines, subsea pipelines, but reference is also made to the protection of other subsea equipment, subsea structures, risers, and shore approaches. The corrosion protection of pipelines (either onshore or subsea), which operate at elevated temperatures and therefore require the application of an anticorrosion and/or thermal insulation coating capable of withstanding such corrosion is also covered.

Two case studies, design examples, and my experience as a pipeline integrity engineer is featured in this book.  Readers should have a high quality and in-depth understanding of the corrosion protection methods available and apply them to solve corrosion-engineering problems.

Fire has been both a friend and an enemy to humanity. Confined and controlled, it warms homes, used for cooking, powers machinery, frighten predators, and makes production of new materials possible. When it escapes uncontrolled, fire destroys properties, lives, and businesses.

 

Examples of the destructive potential of uncontrolled fire on offshore platforms range from historic fires that virtually destroyed Petrobras Enchova Central platform, Piper Alpha platform, Ubit platform, Petrobras P36, Fulmar A, Mumbai High North platform, Ekofisk A, Nowruz platform, and so on. Events such as these have prompted structural engineers in the oil and gas sector to review causes, evaluate means of minimizing re-occurrence, and institute provisions for fire resistance and fire protection.

Fire will always be a major threat to the offshore structure as oil and gas always passes through the installation. The design against accidental fire situation should be included in the structural design of offshore structures in collaboration with safety engineers. The design of offshore structures for fire safety involves considering fire as a load condition, assessment of fire resistance, use of fire protection materials, and so on.

This book presents a methodology that will enable an engineer to design a fixed offshore platform to resist fire. It aims to highlight the major requirements of design and to establish a common approach in carrying out the design.
