摘要： The present invention relates to systems and methods for finding and sampling hydrocarbons from seeps in water or from artificial sources of water. The present invention related to systems and methods for in situ analyzing fluid samples in a body of water. The systems and methods can be used to find hydrocarbons and associated non-hydrocarbons from seeps in water. Such seeps may come from natural sources in deep water, possibly as deep as 3000 m or even more.

摘要： This document describes a system for the deployment, towing and recovery of marine equipment from a waterborne carrier, which carrier comprises a hoisting arrangement for lifting the marine equipment into the water. The system cooperates with the hoisting arrangement, and comprises a lateral deployment-recovery assembly for deployment and recovery on a lateral side of the carrier, and includes: a tow winch and an aft lateral outrigger connected to the carrier. The assembly also comprises a tow line guide and a guider winch including a guide line attachable to the tow line guide. The aft outrigger comprises a seat for the tow line guide and a sheave for the guide line to enable guiding of the tow line guide to the seat. The document also describes a method.

摘要： A method, system and computer program product for determining soil properties comprising a probe including at least a liquid injection port and a pressure transducer. The probe is pushed into a soil and one or more pumping tests are carried out, wherein during a pumping test infiltration liquid is pumped through the liquid injection port of the probe. By means of the pressure transducer a pressure response in the soil resulting from the injection of liquid through the liquid injection port is measured for each of the one or more pumping tests.

摘要： Method for determining a spatial property of a submerged object in a 3D-space, using an underwater moveable platform, that is provided with a camera and with a position and orientation measurement system configured to output a position and orientation of the camera. The method includes receiving user input for visually fitting a bounding volume to the object, and determining the spatial property of the object based on a corresponding spatial property of a bounding volume once the user is satisfied that the bounding volume sufficiently fits the object. The method provides an interactive manner of visually fitting the bounding volume to the object, based on images of the object taken at different positions and/or orientations of the camera relative to the object, as well as on a representation of a position and orientation of the camera in the 3D space at the time each image was captured.

摘要： A system for surveying the structure beneath the seabed, comprising: a survey vessel; a streamer comprising a cable, a first set of N1 sensor groups positioned at a first end portion of the cable, the sensor groups of the first set being spaced from each other by a group interval, and a second set of N2 sensor groups positioned at a second end portion of the cable, the sensor groups of the second set being spaced from each other by the group interval; a sound source; wherein, when the system is in use, the survey vessel travels at a predetermined speed, towing the streamer and the sound source such that the sound source is positioned adjacent an intermediate portion of the cable between the first and second end portions of the cable; the sound source sends acoustic pulses at a predetermined period between pulses towards the seabed such that reflections are produced towards both the first set of sensor groups and the second set of sensor groups; and the speed of the survey vessel and the predetermined period of the sound source are selected such that the shot point interval of the sound source equals the group interval.

摘要： The present document describes a method of hauling an equipment unit from the water onto a carrier. The carrier comprises a hauling ramp, which is arranged for being extended from a loading area into the water. The carrier further includes a first winch, and a suspension structure arranged for being extended outside the carrier over the water and over the hauling ramp. The suspension structure comprises a second winch. The method comprising the steps of: releasing, by the equipment unit, a hauling buoy. The hauling buoy is connected to a tow line extending from the equipment unit, and to a lift line extending from a lifting point on the unit. The method comprises a further step of recovering the hauling buoy from the water, connecting the tow line to the first winch and connecting the lift line to the second winch. Then, the equipment unit is hauled by towing it onto the hauling ramp using the first winch, while simultaneously guiding the equipment unit using the second winch. The method is in particular useful for hauling of an autonomous underwater vehicle (AUV) during bad weather conditions at sea. The document also describes the equipment unit and a system for hauling that can be installed on a carrier, as well as a carrier comprising such a system.

摘要： Method for precise GNSS positioning system with improved ambiguity estimation. The method is based on the realization that, especially during convergence, the estimated float ambiguities are biased when estimated simultaneously with the ionosphere parameters. The “ionosphere-like” biases can be separated from the actual float ambiguities by using the fixed wide-lane (or extra wide-lane) integer ambiguities. The original real-valued ambiguities (e.g., one of L1, L2 and L5 in the GPS case) are corrected using the corresponding biases, resulting in reliable float ambiguities that are taken as input in the next processing step.

摘要： Mobile Offshore Drilling Units (MODUs) are more susceptible to meteorological conditions such as winds, currents and, most importantly, waves. These meteorological conditions generate a movement of the installation that will inevitably be transferred to some extent to the drilling pipe. A mobile offshore drilling unit can include a rooster box configured to move the rooster box along the height of a derrick to which it is attached. An injector configured to attach to an intervention frame of the rooster box, wherein the injector is configured to be releasably coupled to a conduit The injector configured to be positioned on-axis with the conduit in a first configuration and off-axis with the conduit in a second configuration.
