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.

Abstract: In a method of reinforcing a pipe, a water penetration resistant layer and strengthening layer of fibrous material are impregnated with a curable polymer, positioned in a lining position near the pipe, and cured to form a water penetration resistant liner and a strengthening liner. The two layers can be impregnated and positioned separately or at once, for example, as a composite liner. Together, the liners provide a waterproof barrier and structural reinforcement to the resulting pipe. In a method of waterproofing a reinforced pipe, a water penetration resistant layer is impregnated with curable polymer, positioned over a previously installed reinforcing liner, and cured to form a waterproof barrier inhibiting ground water egress into the pipe. In certain embodiments of the methods, the water penetration resistant layer includes fibers woven in one of a satin weave and a twill weave.
