Abstract: A vessel system includes a hull configured to provide buoyancy, one or more seismic sources configured to generate seismic energy, and a deployment apparatus configured to deploy the seismic sources from the hull to a water body or water column. A control system can be configured to operate the deployment apparatus, in order to deploy the seismic sources.

Abstract: A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source (e.g., air gun array) of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and the source. A floatation device supports the source and tows below the water's surface to avoid ice floes or other issues encountered at the water's surface. Seismic streamers have head floats supporting the streamers. Each of the floats has adjustable buoyancy preconfigured to counterbalance the weight in water of the towed component that the float supports. Acoustic signals from a transceiver at the vessel find locations of the towed components. A towed fish at a lower level than the towed components also uses acoustic signals with a transceiver to further refine the locations of the towed components.

Abstract: A seismic spread is constructed having an arrangement of towed components to be neutrally buoyant in water when towed in a seismic survey. The towed components at least include streamers and paravanes. Immersed weight and drag of the towed components is determined, and drag forces versus buoyancy required to neutrally buoy the towed components at at least one tow speed in the water is calculated based on the determined weight and drag of the towed components. Floatation is configured for the seismic spread based on the calculated drag forces versus buoyancy; and the arrangement of the towed components in the seismic spread is constructed with the configured floatation.

Abstract: A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and source. A floatation device supports the source and tows below the water's surface to avoid ice floes. The streamers can have vehicles deployed thereon for controlling a position on the streamer. To facilitate locating the streamers, these vehicles on the streamers can be brought to the surface when clear of ice floes so that GPS readings can be obtained and communicated to a control system. After obtaining readings, the vehicles can be floated back under the surface. Deploying, using, and retrieving the system accounts for ice at the surface in icy regions. In addition, handling the seismic record can account for noise generated by ice impact events.

Abstract: A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source (e.g., air gun array) of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and the source. A floatation device supports the source and tows below the water's surface to avoid ice floes or other issues encountered at the water's surface. The floatation device has a depth controlled float and one or more adjustable buoyancy floats. The controlled float has its buoyancy controlled with pressurized gas used for the air gun source and actively controls the depth of air gun source in the water. Each of the adjustable float connects in line with the controlled float with flexible connections. Each adjustable float has its buoyancy preconfigured to counterbalance the weight in water of the air gun or portion of the source that the float supports.

Abstract: An example system includes a first seismic source configured to emit seismic energy by generation of a first air bubble into the seismic medium at a first time, and a second seismic source spaced a predefined distance from the first seismic source. The second seismic source is configured to emit seismic energy by generation of a second air bubble into the seismic medium at a second time after the first time. The seismic energy has a low frequency characteristic.
