摘要:
A cargo vessel comprises two or more narrow boats or barges (2,4) suitable for use individually on inland waterways, which, when close-coupled together along a longitudinal line (6), are suitable for use as a sea-going vessel. The arrangement reduces the cost of inter-continental carriage of cargo by eliminating the need for trans-shipment of goods from barge to sea-going vessel and back again to barge whilst encouraging the use of inland waterways.
摘要:
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.
