SPT installed nine (9) suction piles of OD 5.5-6.5m x 10-11m deep for Bibby Offshore . The suction piles will be used to moor the Ithaca Athena FPSO in 140m water depth.
SPT’s strong SAPS-004 suction pump was used. Actual suction time was only 30 minutes per suction pile. The SAPS-004 suction pump was docked subsea using the ROV. Release was also accomplished following installation by remotely control and monitored by ROV.
SPT Offshore is an independent offshore contractor specialised in suction pile foundations and Self Installing Platforms (SIPs) ® for the development of marginal oil and gas fields and offshore wind farms.
