Core Completes Grouting on Sandbank Offshore Substation for Seaway Heavy Lifting

Core Grouting Services has recently completed the grouting on a 4 pile offshore substation for Seaway Heavy Lifting (SHL). The project required Core to mix and pump approximately 130 tonnes of high strength grout material into 4 subsea pile skirts for securing the jackets structure to the foundation piles.

The installation was completed in approximately 25 metres water depth in the German North Sea. Core cooperated with the grout material supplier, Sika, to bring their SikaGrout 3500 material through the German approvals process for offshore grout.

The grouting was completed using one of Core’s high capacity grout mixing and pumping units. These units are specially designed to produce large amounts of high strength material to enable grouting to be completed as quickly as possible.
