FRACAS Analysis, Part 3
This week’s tip continues discussing the Analysis phase of FRACAS. As mentioned in last week’s tip, there are a number of Problem Resolution/Root Cause Failure Analysis (RCFA) processes and tools that are available. Figure 1 below illustrates a typical process that...

This week’s tip continues discussing the Analysis phase of FRACAS. There are a number of Problem Resolution/Root Cause Failure Analysis (RCFA) processes and tools that are available. So many, in fact, that a variety of books and guides have been written on both the...

The Analysis part of FRACAS can at times be the most difficult, challenging and even fun (yes, fun!) phase of the overall FRACAS process. This phase is focused on determining the cause(s) of the failure. Let’s start with a couple of definitions of two different types...

Last week I provided an introduction to Failure Reporting, and its importance. This week, I'll go a bit deeper. I've always stressed two things when talking about Failure Reporting: Report the failure! I know, it sounds silly. But if you aren’t doing any type of...

Last week I introduced Failure Reporting, Analysis and Corrective Action System, otherwise known as FRACAS. This week, I'll talk about the "FR" ... Failure Reporting. Let's start by defining what a failure is. There are many, but I prefer this one: A failure is a...

We've been busy helping clients save money, and yes, it involves an acronym. Not another acronym! Failure Reporting, Analysis and Corrective Action System … sounds complex, right? FRACAS can be as simple or as complex as you make it. But let’s start with a simple...

In last week's tip, I confirmed that in the diagram below, the primary seal is Seal B and that Seal A is NOT redundant. This week's final tip on connector seals and test ports pertains to the test port itself. Recall from previous tips that the test port is itself a...
read moreBack of the Napkin: Primary Seal
In previous tips, I said that you need a test port and two seals on your subsea connectors so that you can verify the integrity of the primary seal prior to running your equipment subsea. So, which of these two seals is the primary seal? And does this configuration...

... is better than two redundant untested seals. In last week's tip, I said that test ports are a key component of your subsea connector design because they allow you to verify seal integrity. This week, I'm showing the same diagram again because I want to quickly...

During one of my many trial-by-fire experiences with subsea connectors, I had a wise connector supplier (company president) tell me "It's always the other connector design I should have selected". Well, not really funny at the time--down time is expensive and my...
