Why operators need to start thinking about structural centralizers earlier

Posted by Shulla Elgood on 14-Apr-2015 15:00:00

As an experienced supplier to the offshore industry, we’ve witnessed many clients treat centralizers as an afterthought or fall back in their platform repair projects.

The truth is that centralizers can become a much more useful asset to operators when they’re considered earlier in the process.

Here’s 3 reasons to start thinking about structural centralizers now:

Get the right advice for your next well conductor centralizer order

As expected with the decline of the oil price, operators in the North Sea and beyond are turning their attention towards extending their asset’s life, as opposed to splashing the cash on new developments.

Centralizers, operating at the critical interface between the well conductor and the platform structure, provides vital ‘front line’ conductor integrity to support your existing assets wherever you are in the world.

On many new projects, centralizers are left until late in the day in the workscope – this is a mistake as significant cost savings can be made if centralizer design is considered early-on. Additionally retrofit centralizers have been growing in popularity due to an increasing need to secure older well conductors against integrity issues. So, while centralizers may be superficially similar in both these modes of application, the experience and insight needed to design effective units varies.

Worried about conductor integrity? Retrofit centralizers offer a solution

Retrofit centralizers are fitted between the conductor and the guide after the conductor is already in place on the platform. Usually fitted at the splash zone level and subsea guides, retrofit centralizers are used in 6 different scenarios:

  • Where there are doubts about accurate conductor space-out during installation
  • Where conductors have been driven
  • When centralizers were not installed at the point of conductor guide installation
  • When errors in the tally were made with previously-installed centralizers
  • To provide centralization for the guide due to the original centralizer failing
  • Where existing conductor centralizers have significantly exceeded their design lives
