The system can, typically, be deployed in a 23 x 11 meter footprint and can be fitted to any vessel with enough deck area. The configuration of the standard ISO containers is flexible and can be altered to suite specific vessel deck arrangements and vessel dimensions.
The portable source system only requires electrical power and cooling water from the vessel. All other supply and services are self-contained within the standard ISO containerised units.
The three gun string source is deployed over the stern of the vessel and towed approximately 50 meters astern. This arrangement allows for rapid deployment and recovery coupled with very short turning times. This ensures efficient survey operations.
The source system is compact, very safe to recover/deploy and thus is able to acquire data at relatively high speed. The safe handling and inherent robust design allows operations to continue in weather conditions that would stop most other survey operations.
