Offshore floating structure may include one or more mooring lines coupled to an elongated base for anchoring the elongated base to a sea floor. Offshore floating structure may further include a mounting platform coupled to the elongated base and configured to removably couple one or more power support components for supporting one or more offshore operations. The one or more power support components may comprise one or more renewable energy power sources, one or more alternative power sources, one or more power storage systems configured to store and provide energy generated from the one or more renewable energy power sources or the one or more alternative power sources, and one or more electric charging stations configured to receive the energy generated from the one or more renewable energy power sources or the one or more alternative power sources. Offshore floating structure may be manually, remotely, and/or autonomously operated.

Offshore floating structure for offshore power operations

A fluid conduit has a longitudinal flow passage which includes a transverse cross section that is configured as a polygon, such as a convex or a concave polygon.

Low erosion fluid conduit with sharp section geometry

An apparatus for communicating signals across a wellbore barrier defined by a first flow completion system component positioned at an upper end of the wellbore and a second flow completion system component mounted within the first flow completion system component includes a first wireless node which is mounted on the first flow completion system component on a first side of the wellbore barrier, the first wireless node being configured to be connected to an external device, and a second wireless node which is mounted on the second flow completion system component on a second side of the wellbore barrier, the second wireless node being located generally opposite the first wireless node and being configured to be connected to a downhole device. The first and second wireless nodes are configured to communicate wirelessly through the wellbore barrier using near field magnetic induction (NFMI) communications.

Wireless downhole feedthrough system

A method for monitoring a condition in at least one of a plurality of casing annuli in a subsea hydrocarbon production system having a wellhead housing mounted at the upper end of a well bore and a number of concentric well casings extending from the wellhead housing through the well bore, including an innermost casing through which a hydrocarbon fluid is produced. The plurality of casing annuli are defined between successive ones of the wellhead housing and the well casings. The method involves sensing at least a first condition at a first location in a first casing annulus, generating a first data signal at the first location which is indicative of the first condition, transmitting the first data signal from the first location to a second location either outside the wellhead housing or inside the innermost casing, receiving the first data signal at the second location; and transmitting the first data signal from the second location to a remote location at which the first condition may be monitored. The first data signal is transmitted from the first location to the second location using near-field magnetic induction (NFM) communications signals.

Wireless communication system for monitoring of subsea well casing annuli

An apparatus for communicating optical signals between an external device located on a first side of a wellbore barrier and a downhole device located on a second side of the well bore barrier includes a first wireless node which is positioned on the first side of the well bore barrier and is in communication with the external device via a first cable. A second wireless node is positioned on the second side of the well bore barrier and is in communication with the downhole device via a second cable. The first and second wireless nodes are configured to communicate wirelessly through the well bore barrier using near field magnetic induction (NFMI) communications.

A sensor apparatus comprises a first magnetic transducer which in use is positioned on a first side of a barrier and a second magnetic transducer which in use is positioned on a second side of the barrier opposite the first side. The second transducer comprises a magnetic or electrical property which is dependent upon a sensible condition on the second side of the barrier, such as the pressure or temperature on the second side of the barrier. In operation, the first transducer generates a first magnetic field which induces the second transducer to generate a second magnetic field that is dependent upon the magnetic or electrical property of the second transducer. The first transducer detects the second magnetic field and generates a signal which is representative of the sensible condition on the second side of the barrier.

Inductively interrogated passive sensor apparatus

A non-invasive wireless communication system for monitoring parameters existing within the casing annuli of a subsea hydrocarbon production system. The subsea hydrocarbon production system includes a wellhead housing mounted at the upper end of a well bore and a number of concentric well casings extending from the wellhead housing through the well bore, and the casing annuli are formed between successive ones of the wellhead housing and the well casings The monitoring system comprises an interrogation package which is adapted to wirelessly transmit and receive NFM and/or inductive signals and at least one sensing package which is located in one of the casing annuli and is adapted to wirelessly receive the signals from and transmit response signals to the interrogation package.
