Project completed in Aug 2019 using ce200-120G-R Grout
Neptune Subsea was awarded the engineering and supply of the grouting services for the SSB Jacket installation. UHPC grouting operation was required for the piles driven during jacket installation, whereby the annulus between the skirt piles and jacket legs had to be fully grouted. The grout operation had to be performed by conventional grouting method of pumping offshore into skirt pile sleeve annuli for this scope of work. The unique and challenging client requirements for this project specified that an early strength UHPC-type grout capable of achieving compressive strengths of 13MPa at 6 hours, with an excess of 55MPa at 28 days had to be used for this job. Neptune selected ceEntek’s rapid strength development ce200-120G-R grout due to its unique high early strength characteristics exceeding 13MPa at 6 hours after placement.
