CHESS SUBSEA ENGINEERING – INNOVATIVE SOLUTIONS 1.0 Introduction – Basic Definitions The act of giving something up, withdrawing support or help despite allegiance or responsibility. The voluntary surrender of property (or a right to property) without attempting to reclaim it or give away. Abandonment Decommission The act of dismantling, withdrawing or removing from active service. De - Construction The act of breaking down into smaller components or dismantling. Dismantling The act of taking something apart; disassembling; tearing down; to put to an end in a systematic way. 1.1 Basic Definitions 1.2 Offshore Market There are about 6500 offshore facilities worldwide of which two third is in Gulf of Mexico. There are some 600 in the North Sea, 400 of which are on the UKCS. A major proportion of the world's biggest platforms are located in the North Sea. In the UK, within the next 10-20 years, on average, 15 - 20 installations are expected to be decommissioned annually. In addition, several thousands of kilometres of pipelines may have to be removed, trenched or covered. The continental shelf bordering the states of the European Union and Norway has more than 600 offshore oil and gas platforms and several thousand kilometres of pipelines. World-wide about 1200+ platforms have already been removed. The largest number was removed in the Gulf of Mexico (about 100 pa). World-wide expenditure could exceed £50 billion (US$75 billion). For the North Sea's 600+ facilities, estimates of expenditure for future removal vary based on a number of factors. It is assumed that it might cost between £15 - £30 billion (US$20 - 50billion) for total decommission. OFFSHORE DECOMMISSIONING & ABANDONMENT (SODA) LEVEL 2

Such removal shall also have due regard to fishing, the protection of the marine environment and the rights and duties of other States. Appropriate publicity shall be given to the depth, position and dimensions of any installations or structures not entirely removed". The competent international organisation is the IMO. "The International Maritime Organisation is the United Nations specialised agency responsible for improving maritime safety and preventing pollution from ships. We are also committed to technical co-operation. IMO was formed in 1948 in Geneva. 2.2 IMO For further enquiry visit: www.imo.org/home.asp
