Decommissioning Subsea Infrastructure

A method of dewatering a subsea pipeline bundle assembly before lifting the assembly from the seabed comprises adding discrete buoyancy to an elongate carrier pipe of the assembly. The buoyancy elevates one or more portions of the carrier pipe disposed between drainage outlets of the assembly. Each elevated portion defines inclined falls that slope downwardly in opposed longitudinal directions toward the respective outlets. Water within the carrier pipe drains down the falls toward the outlets. Injecting a dewatering fluid into the carrier pipe promotes expulsion of water from the pipe through the outlets by downward displacement of the water. Drainage can be assisted by a venturi effect driven by accelerating the flow of the dewatering fluid at a location in line with an outlet.

Filtration system for preparation of fluids for medical applications

A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.
