This course outlines the hazard, consequences and risks associated with operation of offshore structures and pipelines, details the conventional and stress-associated degradation mechanisms and the range of inspection and testing methods that can be applied. The options for degradation control are presented with case histories of both failures and successes. Where pro-active maintenance has been ineffective then the course details typical cost-effective repair procedures that are available. Particular emphasis is placed on pipeline networks where it is necessary to combine statistical analyses with modeling to prioritize the inspection programme. Corrosion monitoring requirements are covered and the possible advantages of advanced monitoring techniques are outlined. Cathodic protection surveying and retrofitting are also detailed in the light of the new CP design code for submarine pipelines. As part of the course the delegates will be expected to partake in an inspection programme planning exercise.


Upon the successful completion of this course, each participant will be able to:-

  • Apply and gain an in-depth knowledge on inspection & maintenance of subsea pipelines & offshore structures
  • Discuss the philosophy of Inspection, Maintenance and Repair (IMR) and identify the types of risk assessment approach used in IMR
  • Explain the structural failure modes of jackets including fatigue, risers, dropped objects, pipeline jacking and scour mechanisms and employ the various procedures in the inspection and repair of subsea pipelines and offshore structures
  • Enumerate corrosion issues such as seawater corrosion & corrosion under marine fouling and explain its recommended practices
  • Discuss subsea pipelines particularly their construction and list down some case histories of problems encountered during pipeline construction
  • Employ the latest procedures of hydrotesting, recognize its importance as an inspection tool and describe the concept of free span including the use of sidescan sonar and laser camera systems in evaluation and repair of free spans
  • Explain the on-bottom stability by describing the design of weight coatings and identifying the impact of climate change on pipeline stability and the additional provisions on bottom stability
  • Determine the various subsea pipeline failures and the different methods of repair of damaged subsea pipelines and explain the concept of cathodic protection including the design codes, methods of CP surveying, analysis of data & coating condition
  • Describe internal corrosion comprising its morphology, inspection, monitoring and evaluation, identify the various types of pigging and explain their features, functions and limitations
  • Implement the statistical methods used in corrosion data evaluation and the various procedures used in the prevention of corrosion
  • Carryout methods of cathodic protection retrofitting and demonstrate the calculation method to evaluate protection limits

This course is intended for structural, pipeline and subsea engineers as well as integrity, corrosion, inspection and maintenance engineers. The risk assessment approach will have direct relevance to the work of planning and project engineers and to the managers charged with control and prioritization of the inspection and control programmes.
