Patent ID: 10161247

Abstract:
An ROV-mountable flush and sample skid is described that reduces the project cost and deliveries, and also improves HSE risk during Subsea Pump installation campaigns. The ROV skid can be configured as part of a standard ROV tooling across different projects. The tool also reduces the total pump module installation weight that is important in deepwater applications. The ROV-mountable flushing and sampling skid is mounted to an ROV and deployed to a subsea location to provide flushing of and sampling of barrier oil from a barrier oil supply jumper from an subsea umbilical termination assembly. The Subsea pump flushing and sampling ROV skid includes of a set of flush accumulators with enough capacity to flush the installed jumpers clean, and also one or more sample accumulators configured to sample the barrier oil after the flushing has been performed.
