Nine offshore hazards that could affect your conductor's structural integrity


Standing unprotected for over 25 years, it is quite understandable why structures fatigue. Whilst conductors, along with jackets, risers and topsides can begin to crack or water-tight integrity is breached, you need to ensure all existing assets are inspected and monitored on a regular basis. Designs for adequate fatigue life extension products should take into consideration this research.


Across the platform, cracking, erosion and loss of wall thickness can all be the result of corrosion. This natural wear should be monitored throughout the asset’s life, not just when damage occurs, and corrosion protection should be implemented as soon as possible.


Denting, buckling, severance and cracks can all occur from dropped objects with conductors, supports and risers at risk. The management of crane operations and design of key members for future structures should be looked into to avoid accidental collisions.


Whilst the jacket is most at risk to the consequences of a ship collision, of course, the whole structure will be affected. Dents, cracks and buckling of structure can occur in the short or long term depending upon the original impact. As well as warning systems of collisions, a structure designed for adequate energy absorption should be a part of your asset already.


Everything from the conductor to the caissons are exposed in the event of a fire or a blast on the platform. A loss of structural stability, and any blast damage to steelwork, because of an incident needs preventing by implementing detection and warning systems as well as reducing the sources of leaks.


Accurate station keeping is essential to ensure integrity of the riser/conductor systems and all other connections to the seabed. Generally reliant upon the integrity of the mooring system implemented, it’s vital to ensure the system is too, not affected by corrosion, fatigue or any geotechnical disruptions.


As operators begin to explore new ways of using existing assets, it’s important to remember that a change of use to the platform can be classed as a hazard you should be monitoring. New machinery and processes bring new hazards to avoid. Weight management is also something to think about – heavier machinery could compromise the platform’s current condition and add stress that devalues the structure.
