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 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 translation: 一根skeg从拖船的船尾安装，并延伸到水线以下。 skeg中的通道可以保护用于蒸笼的电缆和从容器部署的地震系统的源。 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，以避免浮冰。 拖缆可以在其上部署车辆以控制拖缆上的位置。 为了便于定位拖缆，拖缆上的这些车辆可以在没有浮冰的情况下被带到地面上，从而可以获得GPS读数并传送给控制系统。 获得读数后，车辆可以浮在表面下方。 在冰冷地区的表面部署，使用和检索系统帐户。 此外，处理地震记录可以解决冰影响事件产生的噪音。

Abstract: An automated storage and retrieval system for seismic nodes includes a modular housing having a first row of rack structures and a second row of rack structures. The system further includes a first receptacle configured to couple a sensor module of a seismic node to a rack structure of the first row of rack structures for storage and reconditioning of the sensor module, and a second receptacle configured to couple a power source module of the seismic node to a rack structure of the second row of rack structures for storage and reconditioning of the power source module.

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: 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: 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 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.
