Portable hydrostatic test tool

Hydrostatic test tool 100 comprises frame 161; pressurizer 120; connection system 110; control system 130; data communicator 140; power supply 150; device handler 162; and buoyancy unit 163. Hydrostatic test tool 100 can 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 5, which could be used to perform other tasks while the test is being carried out, optimizing the total time of support vessel 6 and reducing operational cost. Hydrostatic test tool 100 typically requires interfacing with underwater vehicle 5, e.g., an ROV or AUV, only for deployment/installation and data communication, if at all.
