Nautec has recently completed the provision of subsea strengthening method to repair corroded surface casings of wellheads at a platform offshore Sarawak, East Malaysia.
Upon visual inspection of the platform 2 wells were found to be corroded and immediate measures were taken to arrest further corrosion and repair and strengthen the damaged structural casings.
Nautec used its proprietary NaX™ UHPC materials to grout the wellhead annulus, hereby effectively extending the service life of the conductors.
The NaX™ materials are composed of selected blends of silica sand and special high performance aggregates with an optimised grading. In combination with Nautec’s advanced binder technology based on nanotechnology, the NaX™ products have obtained unique performance qualities.
