Abstract: Systems and methods for positioning objects in underwater environments are provided. The geolocation of a target for an object is determined, and a light source provided as part of a positioning system is operated to project a visible target at that location. The determination of the target location relative to the positioning system can include determining a location of the positioning system using information obtained from a laser system included in the positioning system. The light source used to project the visible target can be the same as a light source included in the laser system. A location of an object relative to the target location can be tracked by the laser system as the object is being moved towards the target location. The described methods and systems utilize one or more non-touch subsea optical systems, including but not limited to laser systems, for underwater infrastructure installation, measurements and monitoring.

Abstract: Systems and methods for monitoring underwater structures are provided. First and second sets of point cloud data that are obtained at different times are compared to determine whether the location of the underwater structure has changed. For detecting vibration, a series of range measurements taken along a line intersecting the underwater structure are compared to one another to determine an amplitude and frequency of any vibration present in the underwater structure. For detecting temperature, the ratio of different components of return signals obtained from a point in the water surrounding the underwater structure is measured to derive the temperature of the water. Leak detection can be performed by scanning areas around the underwater structure. Monitoring systems can include a primary receiver for range measurements, and first and second temperature channel receivers for temperature measurements.

Abstract: A process for the preparation of a compound of formula R1—Y1—P(NR2R3)2 is provided. The process comprises reacting a compound of formula PX3 with a compound of formula HNR2R3 to form a compound of formula X—P(NR2R3)2; and reacting the compound of formula X—P(NR2R3)2 with a compound of formula R1—Y1—H in the presence of a hydrocarbon solvent to form the compound of formula R1—Y1—P(NR2R3)2. R1 represents a phosphorus protecting group; R2 and R3 each independently represent an alkyl, prefer-ably a C1-6alkyl, group, or R2 and R3 are joined, together with the N to which they are attached, to form a 5-7 membered ring; Y1 represents O or S, preferably O; and X represents a halogen, preferably Cl. The preferred solvent is toluene.

Abstract: An interactive geospatial data provisioning application presents a graphical user interface operable to present a map of geographic regions and corresponding geospatial data sets. The user selects the area of interest from the mapped regions corresponding to the available geospatial data sets. The application identifies geospatial data sets within the area of interest. By analyzing the attributes available in the identified geospatial data sets, the geospatial data application determines the operations applicable to the data sets. A set of transformation rules computes the operations available for a particular selection of geospatial data sets. A custom plugin generator allows a user to define and insert geospatial operations into the provisioning sequence. The application presents the available predefined and user defined operations, and the user select the geospatial data operations to apply from among the available operations.

Abstract: An interactive geospatial data provisioning application presents a graphical user interface operable to present a map of geographic regions and corresponding geospatial data sets available. The user selects the area of interest by panning and zooming over the mapped regions corresponding to the available geospatial data sets. The application identifies geospatial data sets within the area of interest. By analyzing the attributes available in the identified geospatial data sets, the geospatial data application determines the operations applicable to the data sets. A set of transformation rules computes the operations available for a particular selection of geospatial data sets. The application presents the available operations, and the user select the geospatial data operations to apply from among the available operations.

Abstract: An item of clothing the width of a component part of which can be adjusted by the user, the clothing item having a line or cord (1) at least partly encircling the relevant part, which cord can be pulled by the wearer to adjust the width or tightness of the part by means of gathering of the material of the part around the line or cord. For the part of the circumference of the relevant part the cord is concealed under the material but emerges at a desired point and them passes again to the inside of the item of clothing so as to form a cord pull section (6) on the inside of the clothing. The clothing item includes means (5) for holding the component part in its tightened or gathered condition about the cord, the cord pull section (6) being used by the wearer for adjustment of the width of the relevant part.
