  • Apparatus and method for subsea liquid mixing and sampling
    Patent number: 10174866
    Abstract: A submersible mixing and sampling apparatus with submersible supply systems (12, 14) for first and second liquid components such as a thermoset resin and a curing agent is disclosed. Each supply system has a respective submersible tank (24) for holding a respective one of the liquid components. Submersible mixers (46, 48, 50) downstream of the supply systems mix the liquid components underwater to form a curable mixture for injection into a subsea chamber such as a tee (102). Submersible sampling devices downstream of the mixers take samples (94) of the mixture underwater before, during and after injection, and optionally also at the surface. The samples may be cured and tested underwater or may be lifted to the surface for testing. The apparatus may be mounted on a subsea skid (100) or basket.
