Hydrostatic test toolcomprises frame; pressurizer; connection system; control system; data communicator; power supply; device handler; and buoyancy unit. Hydrostatic test toolcan be used to perform an in situ seal test of subsea equipment connectors with limited support from external systems, allowing optimization of subsea operations by not requiring constant support from underwater vehicle, which could be used to perform other tasks while the test is being carried out, optimizing the total time of support vesseland reducing operational cost. Hydrostatic test tooltypically requires interfacing with underwater vehicle, e.g., an ROV or AUV, only for deployment/installation and data communication, if at all.

In various embodiments, a tubular comprises a tubular outer sheath defining an inner void; one or more core elements or assemblies disposed within the inner void; and a substantially solid filler in various embodiments disposed within and substantially filling the inner void, where the filler is adapted to give the tubular hoop strength in a crush situation and comprises a polymer with a density of at least 1.0. In some embodiments, these core assemblies comprise an extruded polymer layer typically extruded about core elements in a single pass, fitting about them without a sharp edge and defining an outer shape. The resulting tubular can comprise multiple regions which, though substantially filled, are filled with differing fillers densities.
