    Abstract: 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.

    Abstract translation: 本发明一般涉及一种在线压力补偿器，其通过将压力补偿流体传递到FACT的内腔中来补偿在现场组装的电缆终端（FACT）结构中暴露于高压和极端海底深度时的体积变化。 本发明可以包括柔性内部部件和外壳状部件。 内部部件可以包括两个边缘焊接波纹管的同心环，它们连接在一起并缠绕在端部的内部部件或外部部件的内部部分上。 波纹管中的内部空隙可以填充压力补偿液体。 压力补偿流体直接扩散到终端组件的流体填充空腔中。 外部部件可以包括适于保护内部波纹管部件并提供海水以填充围绕波纹管装置的周边的空间的壳体。

    Abstract: 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.
