Reef Subsea awarded Seabed Dredging contract by A/S Norske Shell
The project objective is to perform final seabed preparation for pipelay within narrow geometrical tolerances (+/- 20cm) and with a curved route to follow.
The project objective is to perform final seabed preparation for pipelay within narrow geometrical tolerances (+/- 20cm) and with a curved route to follow. The dredging and rectification works will be achieved at the Ormen Lange Mid-North Field Development at a water depth of about 950m, with an uneven seabed mainly composed of hard clay. The contract has an option for similar work to be accomplished for Ormen Lange Further North development.
The Scanmachine 4, which has been available since January 2012, is the new generation of this robust, precise and flexible tool carrier platform. It has retained the existing proven design and added key improvements in technology and the ability to function in deep water up to 2500m. The Scanmachine 4 also benefit from a new generation of Control System to achieve high precision monitoring of the situation on the seabed. In this Project, the Scanmachine will be fully integrated with the Ormen Lange in-field LBL positioning system that improves positioning subsea.
