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 translation: 一根skeg从拖船的船尾安装，并延伸到水线以下。 skeg中的通道保护用于蒸笼的电缆和从容器部署的地震系统的源（例如，气枪阵列）。 skeg上的牵引点位于水面以下，并连接到拖车以支撑蒸笼和水源。 漂浮装置支撑水面下面的水源和水道，以避免在水面遇到冰川或其他问题。 漂浮装置具有深度控制的浮子和一个或多个可调节的浮力浮子。 受控浮子的浮力由用于气枪源的加压气体控制，并主动控制水中气枪源的深度。 每个可调节浮子都与可控制的浮子连接，具有灵活的连接。 每个可调节的浮子具有预先配置的浮力，以平衡气枪的水中的重量或浮子支撑的源的部分。

Abstract: An attachment system for releasably attaching a sensor node to a cable when in a coupled state includes a clamp base and a clamp grip. The clamp base is fixed to a surface of the sensor node. The clamp base further includes a latch that is biased in a latched position when the attachment system is in both the coupled state and an uncoupled state. The clamp grip is pivotably attached the clamp base and biased in an open position when the attachment system is in the uncoupled state. The clamp grip is secured to the clamp base by the latch when the attachment system is in the coupled state.

Abstract: A seismic node deployment system comprises a cable supply with one or more seismic nodes configured for coupling to the cable at one or more attachment locations for deployment to a water column. A node attachment system is configured to drive a portion of the cable into periodic or reciprocal motion so that the attachment speed is substantially reduced relative to the speed at which the cable is deployed.

Abstract: An unmanned vessel system can include a hull system 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 system to a water body or water column. A control system can be configured to operate the deployment apparatus, in order to deploy the one or more seismic sources so that the seismic energy propagates through the water column. A compressed air source can be provided on board the unmanned vessel system, with a source line configured to provide compressed air to the seismic sources.

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: An unmanned seismic vessel system can include a hull system configured to provide buoyancy and a storage apparatus configured for storing one or more seismic nodes, each seismic node having at least one seismic sensor configured to acquire seismic data. A deployment system can be configured for deploying the seismic nodes from the storage apparatus to the water column, where the seismic data are responsive to a seismic wavefield, with a controller configured to operate the deployment system so that the seismic nodes are automatically deployed in a seismic array.

Abstract: A marine seismic surveying apparatus for obstructed waters includes a deployed device and a buoy. The deployed device is disposed at an end of a streamer and is towed below a surface of water. The buoy extends from the end of the streamer to the water's surface. A coupling connects the buoy to the end of the streamer and is breakable due to tension from the buoy obstructed at the surface of the water. A receiver associated with the buoy obtains location information via the buoy at the water's surface. The deployed device can reckon its location with an inertial navigation system in place of location information obtained with the buoy's receiver. Also, the buoy can be deployed at the surface of the water, and more than one buoy can be available for deployment should one be lost.
