  1. HOW TO MANAGE EXTERNAL CORROSION

  2. Age distribution of existing installations on the British continental shelf (UKCS) and the Norwegian continental shelf (NCS), ref DTI (2003) and NPD (2003). Only main offshore structures with platforms above water, excluding bridge supports and flare towers, are included in the figure. Data compiled by Gerhard Ersdal 2005

  3. 2007 HSE KP3 REPORT FINDINGS: On more than 50 per cent of installations the ‘State of Plant’ element was considered to be poor. There was a poor understanding of the potential interaction of degraded non-safety-critical plant with safety-critical elements in the event of a major accident Plant degradation creates tensions between the need to remedy basic fabric problems and carry out critical repairs Fabric maintenance is very poor on many platforms, showing inadequate long-term planning by the operators for the lifetime of installations, a lack of regard for the working environment of offshore workers and the risks to the individual of injury The poor condition of many platforms has increased the risks of injury to personnel from dropped objects, hand lacerations and falling through gratings.

  8. ACCELERATING FACTORS • Water Traps • Mixed Metals • Saltwater Conditions.

  9. ACCELERATING FACTORS • water traps • mixed metals • saltwater conditions. This substrate is severely rusted after less than two years

  10. Water Traps

  11. Mixed Metals

  12. Salt Water

  13. North Sea = Salt Water

  14. HOW CIST CAN HELP …

  15. EASY TO REMOVE FOR INSPECTION …

  16. ENVIRONMENTALLY FRIENDLY • Waste free • Re-usable • Recyclable • Non-toxic REDUCES ACCIDENTS Reduced maintenance means reduced accidents. In the Australian Mining Industry, accidents related to conveyor bearing replacement were reduced by 80% after using CIST for protection.

  17. IN CONCLUSION • Eliminates corrosion in stored components • Eliminates need for bolt replacement • Increases component lifetimes • Reduces accidents and downtime As a simple and effective means of asset protection, CIST has the capability to provide solutions for a wide range of the maintenance and integrity issues raised by UK HSE and other safety authorities
