The team at Core are experienced in the application of grout for integrity and repair of offshore structures. Two of the main applications of grout for integrity are grout bags and structural strengthening with grout.
Grout bags or subsea fabric formworks are used for pipeline freespan rectification and stabilisation of structures.
The grout bags are deployed to the sea bed and filled from the topside using our ordinary Portland cement grouting spreads. The bags which are designed in-house by the Core team are manufactured from a high quality durable woven fabric
The bags are manufactured to meet the specific requirements of the client and the project. Depending on project requirements bags can be positioned by ROVs or by divers. Please see our Grout bag catalogue and grout bag case study
Repair & Strengthening
Over time offshore structures may become damaged or need repair due to corrosion, collisions or fatigue. Grout can be used to address this degradation in the load bearing capacity of the structure. For example grouted clamps can be used to repair damaged parts of the platform enabling the structural strength to be brought back to design conditions.
Grouting can also be used to increase the load bearing capacity of a structure in advance of new topsides being installed. The grout is used to stiffen the structure or add further bracing to it.The Core team is experienced in the usage of grout for structural strengthening of offshore structures. Please see our case study on marine pile strengthening.
