Abstract: Techniques and devices to assist an offshore unit in going on location and coming off location. A device may include an interface configured to receive a signal indicative of motions of an offshore unit. The device may also include a memory configured to store a set of values corresponding to acceptable motions of the offshore unit, as well as a processor configured to determine if a measured motion of the offshore unit exceeds at least one value of the set of values and generate an indication that going on location by the offshore unit can be undertaken when the processor determines that the measured motion of the offshore unit is less than or equal to the at least one value.

Abstract: Semi-submersibles are subjected to loading from waves, causing racking, longitudinal shear and parallelogramming, or differential movement of the pontoons. The cyclic wave loading makes the various connections, where stress concentrations occur, susceptible to fatigue damage throughout the hull structure. This is most evident at the connections between the braces and the main hull structure. A revised brace to main hull connection with reduced bending stiffness is employed to reduce the moment being transferred from the brace to the hull, thereby reducing the bending stress and susceptibility to fatigue damage. This improved connection employs an internal member to transfer the loads between the brace and hull structure mainly as tension and compression. As a consequence of the improved fatigue performance, the structural weight of the connection can be greatly reduced, thus increasing the capacity with which the semi-submersible hull can operate.

Abstract: A range to fault (RTF) module (100) for use in a system for locating faults in a cable network is discussed. The module includes an input port (101) for coupling the module to a PIM analyzer. The module (100) also includes an output port (102) for connection to the device under test (DUT). In addition to the input (101) and output (102) ports the module is provided with a monitor port (103) for receipt of a PIM signal from the PIM analyzer. The module in this instance also includes two USB ports (104a), (104b) enabling a serial connection between the PIM analyzer and the module (100).
