ClayCutter X ^®

A data sheet for the ClayCutter X is available for download

ClayCutter X^® represents the very best in state of the art trenching and pipeline route preparation technology. It is not limited or compromised by water depth, soil stiffness or the angle of the excavation area. High pressure jet nozzles and water cannons combine to make ClayCutter X^® an outstanding product which is easily deployed and extremely versatile.

The ClayCutter X^® is a unique jetting system powered by high pressure seawater from the surface, provided by AGR's 3,000 hp trenching pumps. The tool has 3 operating modes which may be changed subsea with a suitable ROV.  This flexibility allows operators to choose between jetting modes suited to general trench excavation, trench widening, and very hard soils excavation. 

ClayCutter X^® is deployed from a DP II vessel of opportunity and does not require direct contact with the seabed.  It can deliver the deep trenches and glory holes required for pipeline ice protection.

Benefits

• Reliable trenching in various soils up to 500 kPa shear strength (10 ksf)
• Opens up otherwise unusable pipeline routes
• Reduces the requirement for rock dump and other subsea intervention
• Rapid, robust and reliable during rough handling
• Configuration can be changed subsea to save time
• Unlimited trench or hole depth
• No restrictions on seabed angle        
• Can be deployed from vessels of opportunity worldwide 

Applications

• Pipeline route preparation in difficult seabed areas
• Seabed excavation prior to platform removal
• Deep trenching for ice scour protection 
• Seabed levelling for manifold installation
• Mud line cellars and glory holes in ice-prone areas
• Shore approach pre-trenching in competent soils and soft rock areas
