OceanWorks delivers design-build project for PanGeo Subsea
Posted: 11 August 2008
OceanWorks has delivered a high accuracy mechanical positioning system to PanGeo Subsea Inc. This system is deployed to the seabed, and with PanGeo’s acoustic imaging technology can detect and locate buried pipelines or geohazards such as large boulders.
The system can be transported, launched, and recovered in a folded configuration. Using a small hydraulic power unit the arms and legs are extended as it nears the seabed.
They system can be deployed in up to 600 meters of water from a typical oilfield support vessel.
Once deployed it has a survey area of 12m in diameter, producing a 3D acoustic image to a typical depth of 20m.
A custom, direct drive motor is used for boom rotation and belt drives are used for positioning payloads along the booms.
This allows the PanGeo acoustic packages to be very accurately positioned over the seabed in a 10 cm sampling grid.
OceanWorks scope of supply included the design and manufacture of the structure, mechanical systems, hydraulic and telemetry systems, fabrication, assembly and test.
