FoundOcean - Subsea Engineering - Offshore Grouting, Platform Repair and Flooded Member Detection

FoundOcean is the world leader in the provision of premium quality structural and pipeline grouting services. FoundOcean is a specialist engineering company within the oil and gas industry, offering a tailor-made range of services including foundation and structural grouting, structural repair, offshore grouting, underbase grouting, platform repair, pile grouting and pipeline support and protection. In addition FoundOcean manufactures a range of anti-scour products and provides structural inspection services.

OFFSHORE GROUTING AND PLATFORM REPAIR

FoundOcean's involvement in the offshore industry dates from the Umm Shaif and Zakum oil fields in the 1960s. This experience was transferred to the North Sea in the early 1970s for the installation of the BP Forties platforms.

Since that time FoundOcean have worked on the successful installation of numerous jacket and template structures in all producing areas of the world. FoundOcean have worked for all of the major offshore installation contractors, and most of the world's oil and gas operators.

A comprehensive track record encompasses nearly 300 structures and more than 2,000 high strength structural sleeve connections as well as numerous structural repairs and pipeline stabilisation projects.

FoundOcean have 24 years of experience in subsea engineering. A name change in 2005 saw FoundOcean move away from subsea markers, which were produced under the company name Seamark Systems.

FOUNDATION PILE GROUTING

The core service provided by FoundOcean is foundation pile grouting for the installation of new oil and gas platforms. The grout mixing equipment is specially designed for this purpose and is capable of mixing cement grouts to the very high densities required for high strength connections.

FoundOcean provides grout monitoring services to measure grout density in the pile / sleeve annulus. This equipment is mounted on an ROV, with grout density readings displayed in the ROV control cabin.

A further development of the technology used for ROV grout monitoring is the HydraScope flooded member detection system. This service enables rapid and cost-effective inspection of offshore platforms to check that members have not become flooded as a result of damage, or defective welds.

GROUTED CLAMP - STRUCTURAL REPAIR

FoundOcean supplies three types of structural repair:

• Grouted clamp
• Stressed grouted clamp
• Grout filled tubular

The major advantage of using a grouted clamp is that the grouted annulus offers a large tolerance and therefore reduces fit-up problems. Repair can be carried out at any depth within the range of the structure.

PIPELINE SUPPORT AND STABILISATION

FoundOcean manufactures a range of fabric formworks for pipeline support and stabilisation. This range of fabric formworks can be deployed either by diver or ROV. Fabric formwork is a flexible shuttering, constructed from woven fabric, which is subsequently filled with cement grout.

FoundOcean's ScourMat causes the deposition of sands and sediments to counteract seabed scour to protect structures and reduce pipeline freespan, where erosion has occurred underneath a pipeline. Installation is simple and cost-effective.

FoundOcean also manufactures and supplies concrete mattresses.
