A method of generating scintillation prediction data comprises: a) for a plurality of satellites (12A), and reference stations (10A, 10B, 10C, 10D) measuring phase scintillation data, satellite by satellite for each reference station during multiple epochs (t-2, t-1, t, t+k); b) forecasting an expected phase scintillation value for each satellite and reference station for a period of at least 24 hours based on a cyclical prediction model; c) for a given user location (20) and a given satellite, spatially interpolating the expected phase scintillation values of the plurality of reference stations to determine a predicted phase scintillation index; d) repeating step c) for further satellites visible from the user location.


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 (10) can include a rooster box (2) configured to move the rooster box along the height of a derrick (3) to which it is attached. An injector (20) configured to attach to an intervention frame of the rooster box, wherein the injector is configured to be releasably coupled to a conduit (4).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.

Geotechnical apparatus comprising at least one rod provided with a probe, which rod has a longitudinal bore extending along its body which is in fluid communication with one or more lubricating openings behind the probe for introducing lubricant along the rods superficial area, wherein the apparatus further comprises a drive unit for the at least one rod for pushing said rod into the ground or pulling it from the ground. The at least one rod is a single piece rod and the apparatus comprises a storage for said single piece rod in which the single piece rod is storable in coiled condition and from which the single piece rod is retrievable in said coiled condition, wherein a bender/straightener is provided between the storage and the drive unit to convert the single piece rod between a straightly aligned condition and said coiled condition, wherein the storage is embodied with a guide arm which is rotatable around an axis of rotation and having a clamp distant from the axis of rotation which fixes the single piece rod to the guide arm, so as to arrange that rotation of the guide arm causes the single piece rod to coil or uncoil depending on the direction of rotation of the guide arm.


A method is presented for simulating marine assets (MA) in an offshore operation. The marine assets comprise at least an anchor, a line coupling the anchor with a winch, and a support platform located offshore for supporting the winch. The method involves a computation stage for estimating a state of the marine assets using a computational model and received sensor data (Ds) pertaining to a state of the marine assets and/or of an environment (ME) wherein the marine assets are used. The computational model of the marine assets (MA) includes at least a specification of an anchor, a specification of a winch and a specification of a line coupling the anchor with the winch. The at least a line is modeled as a first portion extending between the winch and a touch-down point where the line touches the seabed and a second portion extending between the touch-down point and the anchor. Additionally a simulation system is presented for simulating the marine asset, and an arrangement including the marine asset and the simulation system.
