AGR Group to Use New Excavation Technology at Ormen Lange

Norsk Hydro has signed a NOK 87 million agreement with AGR Subsea AS to deploy AGR Group's new seabed excavation technology, the Claycutter X, at Ormen Lange in mid 2008, the largest gas field under development on the Norwegian continental shelf.

As an enhancement on currently available technology, the Claycutter X will have a range of excavation modes which can be interchanged subsea depending on the environment encountered. It is controlled remotely and incorporates hands free operation on deck and remote operation of all subsea systems. At Ormen Lange it will be used in conjunction with AGR's Seavator, which uses a high volume vertical flow of seawater to clear debris.

Using the Claycutter X will enable precise excavation in all water depths and soil strengths up to 400 KPA shear strength. Developed in conjunction with the Ormen Lange project, it will be deployed to prepare routes across and through undulating seabed prior to laying pipelines in deepwater.
