A submersible mixing and sampling apparatus 10 comprises submersible supply systems for first 14 and second 12 liquid components such as a thermoset resin and a curing agent. Each supply system comprises a respective submersible tank 24 for holding a respective one of the liquid components. Submersible mixers 16 downstream of the supply systems mix the liquid components underwater to form a curable mixture for injection 20 into a subsea chamber such as a tee. Submersible sampling devices 18 downstream of the mixers 16 take samples 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 or basket. |
