Abstract

See full text

Embodiments of an autonomous seismic node that can be positioned on the seabed are disclosed. The autonomous seismic node comprises a pressurized node housing substantially surrounded and/or enclosed by a non-pressurized node housing. The seismic node may be substantially rectangular or square shaped for node storage, handling, and deployment. One or more node locks may be coupled to either (or both) of the pressurized node housing or the non-pressurized node housing. The pressurized node housing may be formed as a cast monolithic titanium structure and may be a complex shape with irregularly shaped sides and be asymmetrical. In other embodiments, a non-pressurized housing may substantially enclose other devices or payloads besides a node, such as weights or transponders, and be coupled to a plurality of protrusions.
