A connector assembly includes a first and a second releasable and mateable connector. Each connector includes a front assembly composed of a manifold and a plurality of optical stems. Each manifold includes a plurality of inserts and a plurality of spherical seal assemblies. Each seal assembly is composed of a spherical ball, a ball dowel pin, and a ball actuator pin having a cam. Each spherical ball is configured to rotate about an axis defined by the two pins when the actuator pin cam traverses a groove fabricated in one of a plurality of guide rails disposed in the first connector. When the plurality of seal assemblies are in an open configuration, the optical stems of the first connector may slide through the inserts of the first connector, through the seals, and mate with the optical stems of the second connector within the inserts of the second connector.

Latched optical feedthrough system for subsea wellhead penetration using spherical seals

The present invention provides a system for providing a stress reduction apparatus for a ceramic electrical penetrator or pin in a subsea environment. More specifically, the present invention provides a deformable translatable seat in an annular pocket that prevents the transfer of shear forces from a shell or fixture to a ceramic electrical penetrator or pin. The present invention provides a relatively soft metal seat that conforms to the profile of the shoulder of a mating electrical penetrator or pin and deforms to reduce or eliminate concentrated bearing stresses. The deformable translatable seat may also shift and deform within the annular pocket to relieve shearing stresses exerted on the electrical penetrator or pin by the shell or fixture.

Deformable translatable seat for reducing stress on ceramic penetrators

A penetrator device has an outer housing of non-conductive, insulating material having a through bore, at least one conductive pin formed in one or two parts extending through the housing and having a first end portion and a second end portion extending out of the respective first and second ends of the housing, a first cladding layer bonded over the first end portion of the pin to form a first bonded assembly, a second cladding layer bonded over the second end portion of the pin to form a second bonded assembly, and the material of the first and second cladding layer comprising a corrosion resistant conductive material different from the pin material.

The present invention generally relates to an inline pressure compensator that compensates for volumetric changes within Field-Assembled Cable Termination (FACT) structures when exposed to high pressures and extreme subsea depths by transferring a pressure compensating fluid into the internal cavity of the FACT. The present invention may comprise a flexible internal component and an outer shell-like component. The inner component may comprise two concentric rings of edge-welded bellows that are joined together and wrapped around inner components of the termination or of the inner portion of the outer component. The inner void in the bellows may be filled with pressure-compensating fluid. The pressure compensating fluid diffuses directly into the fluid-filled cavity of the termination assembly. The exterior component may comprise a housing adapted to protect the interior bellows component and provide for seawater to fill the space around the periphery of the bellows arrangement.

A modular subsea equipment assembly including a modular base frame and a plurality of modular superstructure devices for selective attachment to the modular base frame for supporting various components and for attachment to underwater cables. The modular base frame includes a frame member forming an outer periphery of the base frame, and a plurality of cross bars extending between opposite portions of the frame member in one or more directions, the frame member and cross bars having at least upper surfaces each having a plurality of connection points for attaching selected modular devices of the assembly to the base frame in a plurality of different possible configurations.

Modular frame system and method for holding subsea equipment

Messages on controller area network (CAN) buses are communicated over subsea links. Repeaters couple CAN buses to each end of a subsea link. The subsea link may be, for example, a twisted pair or a single wire with a sea ground. The repeater detects a direction of transmission, that is, whether a signal began on the CAN bus coupled to the repeater or on the subsea link coupled to the repeater. Signals from the CAN bus are conditionally transmitted to the subsea link depending on the detected direction of transmission. Signals from the subsea link are conditionally transmitted to the CAN bus depending on the detected direction of transmission. The repeater can operate at the physical layer without analyzing contents of the CAN bus communications.

One or more insulated conductive wire assemblies are incorporated in a pressure balanced, oil-filled (PBOF) hose. Each conductive wire assembly has a pair of conductive wires each having an insulation layer, an insulating material surrounding the insulated wires, and an outer insulating layer surrounding the insulating material. The insulating material may be selected to have a dielectric constant substantially matching the dielectric constant of the oil in the PBOF hose, so that the insulated pair of conductors perform in the same way both before and after the assembly is submerged in oil in the jumper hose. One or more parameters of the conductive wire assembly are selected such that the assembly has a predetermined impedance when submerged in oil within the PBOF hose.

The present invention provides optical connectors and optical feedthrough systems that can be mated and unmated in a harsh environment, such as underwater, and is particularly concerned with a method and apparatus for securing and sealing an optical feedthrough or connector from the surrounding turbid environment.

Subsea optical connector using multiple seals

A harsh environment connector has first and second connector units which each have at least one contact chamber in which at least one contact is located. Seal assemblies at the front ends of the respective contact chambers include seal members which rotate about the longitudinal axis of the connector as the units are mated to allow contacts of one connector unit to pass through aligned seal openings and into engagement with contacts in the other connector unit. Each seal assembly has a seal clamp member and the seal and seal clamp members are relatively rotatable during mating and de-mating between a first position when the units are unmated in which the seal openings are clamped shut by the seal clamp member and a second position when the units are mated in which clamp portions of the seal clamp member are offset from the seal openings.

A subsea connector unit with an integrated, bi-directional electrical to optical (EO) media converter is provided which has a first end configured for connection to standard subsea electrical cable connector unit and a second end joined to a subsea optical or electro-optical ethernet jumper cable. The EO media converter has one or more electrical input/output (I/O) junctions which communicate with electrical signal conductors in a connected electrical ethernet cable and one or more optical I/O junctions which are connected to one or more optical fibers extending from the subsea jumper cable. Electrical input signals received at the electrical I/O junctions are converted into corresponding optical signals provided at the optical I/O junctions for transmission along the subsea jumper cable, and optical input signals received from the jumper cable are converted to electrical signals at the electrical I/O junctions for output to the electrical cable.
