    Abstract: A system is used to reduce the bending moments in Coil Tubing (“CT”). The system includes a segmented and closable cage that can close around the CT. The cage includes rollers, such as elastomeric rollers, that can allow for both vertical translations of the CT and rotations of the CT around the vertical axis. The cage rests on a seat, such as an elastomeric seat, provided inside a cylindrical housing. In order to monitor the bending moments in the CT, the pins that hold in the rollers are preferably load pins. This bend limiting system can be located below the CT injector, at the vessel deck level, or in the moonpool. The bend limiting system can be used in offshore or land operations.

    Abstract: A monitoring system for use in a marine riser system coupled to a rig vessel includes one or more subsea inertial measurement units adapted for mounting to a lower end of a riser, an LMRP, or both. The one or more subsea inertial measurement units may acquire time series data of inclination and acceleration. The one or more subsea inertial measurement units may transmit, to a vessel transceiver, frequency data computed from the time series data, low-pass filtered values of the time series data, or both. The monitoring system includes a surface processing unit that is in communication with the vessel transceiver. The surface processing unit may be programmed to compute, for example, fatigue along the marine riser system, the difference between the inclination of the lower end of the riser and the inclination of the LMRP, or both, by applying predetermined functions to the transmitted data.

    Abstract: A mudline closure device is lowered between tensioners coupled to a deck of a vessel or rig onto a subsea wellhead. A tensioner platform is then attached to the tensioners. The tensioner platform includes a platform opening having an inner diameter through which an emergency disconnect system may pass. The tensioner platform also includes rotation bearings secured in the platform opening. A split support includes outer surfaces disposed along its circumference. The outer surfaces are seated on the rotation bearings. The split support includes a support opening having an inner diameter through which a marine riser may pass. The split support also includes a landing shoulder secured in the support opening to suspend a surface blowout preventer to the deck. As the vessel or rig changes direction, the split support rotates relative to the tensioner platform without imparting excessive torsion on the marine riser.

    Abstract: Hang-off and/or torque 1 features are provided on the pipes and/or the connections of a high-pressure riser. The hang-off features may be useful to support the weight of the full length of the riser. Accordingly, the hang-off may be done directly in the middle of the connection, where the strength is the greatest. Also, by using the torque features, it is possible to accommodate large torque values. Accordingly, a large torque resistance may be provided while an upper pipe is being made up. A make-up tool taking advantage of the hang-off and/or torque features permits assembling the high-pressure riser more automatically and with less manual intensive labor.

    Abstract: A system includes several load cells, each coupled to a lashing that secures shipping containers, accelerometer cells, each coupled to a shipping container at the top of a stack, and an inclinometer cell coupled to a cargo ship. The cells are configured to transmit data to a computer. All the cells comprise a processor programmed to acquire a time series of measurements and, preferably, decompose the time series into a sum of sinusoidal signals, each having a frequency and an amplitude. Alternatively, the computer can be programmed to decompose the time series. The computer is programmed to identify the signal components caused by the roll of the cargo ship or by resonances in shipping container stacks. The computer estimates cumulated damages caused by fatigue in the lashings and/or twist locks. The system is used to trigger alarms and/or schedule maintenance.

    Abstract: A repair axial bearing system includes an arcuate rail coupled to a support, one or more bolts protruding upward from a raised portion coupled to a supported member, and a lever plate including at least one low friction bearing pad mounted in the lever plate. A first new bearing surface is formed on the arcuate rail. A second new bearing surface is formed on the at least one low friction bearing pad. The one or more bolts are tensioned with bolt tensioners to press the lever plate against the raised portion. The axial bearing system can include a hydraulic cylinder to slide the second bearing surface over the first bearing surface. The repair axial bearing system can be used to supplant a damaged axial bearing positioned between an FPSO and a turret.
