摘要： A winch is employed for deploying a probe to a precise depth within a water column for making and recording physical measurement within such water column. More particularly, the winch rapidly unspools a line from an underway vessel, while maintaining minimal but constant line tension, as a probe, tethered to such line, descends within the water column in a “near” free-fall to a predetermined depth and then stops. The line lacks means for communicating its depth to the winch. The probe achieves a predictable descent behavior, even though it is tethered by a line to a winch onboard an underway vessel of unknown velocity and in variable weather conditions. The predictable descent behavior is achieved by maintaining a minimal constant tension on the line within a narrow range. The descent behavior of a probe in “near” free-fall has sufficient predictability to construct an algorithm to correlate descent time with depth. The predictability is sufficient to reduce the risk of collision between the probe and the water bottom to an acceptable level.

摘要： Messages on controller area network (CAN) buses are communicated over subsea links. Messages are sent as electrical or optical signals. The present invention provides a subsea CAN BUS electronic distribution unit (EDU) for transmitting, receiving, converting, and routing electrical or optical signals sent over a subsea CAN BUS network. The CAN BUS EDU of the present invention is contained within a single housing and combines the functions of transmitting, receiving, converting, and routing electrical or optical signals sent over a subsea CAN BUS network that would typically be handled by multiple devices.

摘要： The present invention provides systems, methods, and apparatuses for subsea optical to electrical distribution. The present invention comprises one or more routing units adapted to convert optical signals to electrical signals and route the converted electrical signals to an appropriate end device. The routing unit is a compact device that may be installed without the use of heavy equipment.

摘要： A subsea data collection and communication system is installed at a subsea interconnect point or subsea connector used for communication between subsea electrical, optical or hybrid electro-optical cables. The data collection and communication system is configured to collect system performance data such as voltage, current, optical pressure and the like from signals carried by the wires or fibers in cables connected to the connector unit, and may also collect data on environmental conditions from sensors installed in or on the connector unit, such as temperature, pressure, or sea water salinity sensors, and the like. The collected data is transmitted to a remote monitoring station or local hub for further processing to detect potential faults or performance degradation either at periodic intervals or on demand, using bi-directional Ethernet, CANBUS, a carrier frequency system over the cable power lines, optical signal over optical fiber, or wireless communication links over short distances.

摘要： The present invention provides a system and method for providing a seal for an electrical penetrator in a subsea environment. More specifically, the present invention provides for a system for creating a seal about an electrical penetrator without using o-rings or independent seals. The present invention provides for a set of supporting apparatuses to be placed in compression about a central ceramic penetrator element. The geometry of the central ceramic penetrator element and the interior of the supporting apparatuses forms a hermetic seal when under a constant radial and axial, or axial compressive force.

摘要： The present invention relates generally to a modular locking and retaining mechanical design solution to reliably secure immersed, unrestrained and un-powered objects in a fluid environment to a fixed support surface such as a mounting frame or panel, with a quick connect/disconnect engagement method by a diver (i.e. manual mate) or remote-operated vehicles (ROVs) mate, into a fixed mounting frame or panel installed at a subsea deployed platform for oil and gas offshore applications. The invention relates particularly to providing an isolation guide or means to prevent dissimilar materials, metals, of a compact retrievable, horizontal or vertical MCDU configuration and a frame from coming into direct contact to avoid corrosive effects, such as galvanic corrosion.

摘要： A wet-mateable connector unit for use in vertical or substantially vertical orientation in a subsea gas well has an outer shell and a movable wall inside the shell surrounding a pressure compensated chamber containing dielectric fluid. The chamber wall is exposed to ambient pressure outside the connector unit. At least one relief valve is mounted in the connector unit and has an inlet in communication with the upper end of the chamber and an outlet in communication with the external environment surrounding the connector unit. The relief valve opens to release gas from the upper end of the chamber when the differential pressure between the chamber and external environment exceeds a predetermined valve cracking pressure. A plurality of relief valves may be provided.
