Conductor Centralisers

• Protect the conductor and jacket guide from wear, damage and material loss 
• Reduce flowline and tree movement, improving overall well stability 
• Control conductor movement and maintain concentricity to support the required fatigue life 
• Create a neat, close-fitting finish around cellar deck well slots, reducing open gaps and supporting safer offshore access 
• Meet project-specific service-life requirements through engineered coating and fastener systems 

Our in-house team of experienced design engineers provide stringent finite element modelling to present an optimum design which meets industry codes and standards.

Purpose-designed bumper arrangements, controlled dimensions and project-specific material and coating selection help minimise wear and protect both the conductor and surrounding guide structure.

Different coating and fastening systems can also be selected according to the required service life and operating environment. Aquaterra Energy has previously delivered both fixed-blade and cellar-deck centralisers designed for a 50-year service life.For bespoke requirements we can provide designs for:

• Fixed blade conductor centralisers
• Drop-in retrofit centralisers
• Offset retrofit centralisers
• Inner-string centralisers for larger casing strings
• Cellar-deck centralisers, including full hatch coverage for tieback applications, flush recessed and kick plate-mounted configurations
• Adjustable cellar deck centralisers
• Nylon internal centralisers
• Polymer centralisers
• Mechanical and hydraulic remotely adjustable centralisers for specialist applications where physical access is restricted

All designs can be varied, depending on service life, expected conductor or casing-string movement, environmental loading, available access and the configuration of the platform hatch or guide.
