DELIVERING CUTTING EDGE GROUTING METHODS


For over half a century, FoundOcean has been consistently delivering cutting edge grouting methods into the global offshore construction sector


Yet even for a seasoned subcontractor, the rate of change experienced within their niche area, over the last seven years, is unprecedented.


Developments in foundation design, installation approach and contracting, predominantly instigated by the developers’ drive of making the offshore wind industry subsidy free, has manifested itself within FoundOcean through the introduction of numerous service and material-based solutions to the various challenges presented to them.


FOUNDATIONS


Since the early nineties, monopiles have ruled the industry and to a certain extent still do in their various forms. Only a few of the windfarms under construction in 2016 and 2017 were anything other than a monopile. However, these other foundation types are very significant and are a flavour of what is to come in Europe.


The first of these was the jacket foundation. Although previously seen in the first half of the decade at Ormonde and Thornton Bank II and III wind parks, the Wikinger, Beatrice, and East Anglia One in 2018, were the first of the big Round 3 wind parks to adopt the jacket foundation.


The second of the ‘other’ foundation types was the suction bucket. Originally specified at three sites, it is currently positioning itself as a viable alternative, under the right soil conditions, to the driven pile approach.

Nordsee Ost - Grouting Preparations


For FoundOcean these ongoing developments in foundation design and type, has meant that the company needed to ensure it was aligning itself to what was around the corner. So with the help of its strategic partners, it worked hard on its service offering and its offered materials, so that it was ready, with the right solution, for when the time came.


MATERIAL DEVELOPMENT The taxonomy of offshore grouts and their introduction, provides a good illustration of the progress made by the industry in this area, in order to address a particular demand.


Ultra-high strength grouts underwent a renaissance with the introduction of MasterFlow 9500 from BASF. The material’s reliable strength development and long term volume stability, re-instilled the confidence in the concept of the ultra-high strength grouted connection, which was damaged as a consequence of the grouted connection failures between 2005 and 2010.


Although the product was not involved in any of the failures, it was certainly affected. From 2010, the numerous


reported failures contributed towards a fundamental redesign of the connection and the industry’s subsequent forging ahead with the bolted connection, which precluded the use of the ultra-high strength materials.


Yet even this divergence from the grouted connection, gave rise to another material type - MasterFlow 9600 which was born out of its predecessor, MasterFlow 9800.


MATERIAL AND MIXER DEVELOPMENT The product was conceived in 2012, when a gap was beginning to emerge for a material which could offer high strength along with faster and safer delivery rates. What followed was two years of material and mixer development to bring the product to market: This material offered high strength, volume stability and long term durability, as well as faster and safer grouting times, than the ultra-high strength materials that came before it. The target market for this material was the upcoming projects which were going to be using the jacket type foundations.


Unexpectedly however, the need to prevent water ingress into the annulus of the bolted monopile foundation, as well
