UHPC OilWell Binder for local production

Offshore and onshore oil drilling projects and active oil production platforms number in the thousands worldwide. OilWell cement binder is required for all these objects and in large quantities. Until now, these extreme quantities were shipped worldwide to the places of need, transported by truck or by a combination of both, regardless of which transport route was chosen, it was time-consuming and expensive.
Today and in the future, these transport routes will become more complicated, unreliable and much more expensive.

We would like to offer an alternative to the standards used so far. We have been developing and producing UHPC binder systems for more than 25 years. Among other things, we also produce UHPC binders for the offshore industry.

Our alternative to the current transport routes is the production of UHPC OilWell binder on site with local raw materials. After testing the local raw materials, it is possible to quickly determine which OilWell qualities can be produced locally and replace standard OilWell binder from overseas.
For the production, a mobile production unit consisting of three to four containers is used, depending on the desired production quantity, which can load the produced binder into BigBags or silos.

UHPC Grouting of Pile Jacket Annulus at RS 16 Platform, for ONGC, Bombay High, India

Larsen and Toubro Ltd  was engaged in installing two new platforms in the Bombay High field, but due to issues with the specified pressure grouting technique, the jacket pile connection could not be completed on the last remaining leg on the RS 16 platform.
A Danish company was contacted in April 2009 and immediately mobilised all their grouting equipment and personnel together with around 80 tons of special UHPC grouting materials to Mumbai.
UHPC grouting material was specified due to its high compressive strength and modulus of elasticity in the region of four times higher than conventional grouts. In addition, the highly viscous and cohesive nature of UHPC prevents the risk of cement particles washout or being mixed with
water, making UHPC grouting material ideal for use in underwater conditions.

Working from Sapura 3000, a DP Heavy Lift and Pipe laying Vessel, grout hoses were connectedby divers to the pile grout inlet underwater at a depth of 46 meters. Grouting works were carried out 24 hours to expedite completion and all grouting works were
completed within 16 hours. The topside was installed 36 hours after completion of the grouting.


The use of UHPC materials have been proven to provide fast and efficient solutions to structural installations and repairs in the offshore environment.
