Jan Muren – 4 Subsea. Just a quick question on the embedding or measurement devices inside a bend stiffener - I’m a bit concerned about performance of the bend stiffener. What’s your experience in that?

Eric Binet – Technip (Presenter). Is your question linked to the performance of bend stiffener including that equipment?

Jan Muren – 4 Subsea. Yes.

Eric Binet – Technip (Presenter). In fact we’ve tested this. In the bend stiffener we need to adapt the design in such a way you can insert those rods inside it. We’ve performed qualification tests to verify the bend stiffener performances and we have had no particular issue.

Meyrick Hadfield – HSE. Eric, could you say just a little more about the acoustic monitoring for wires failing. Is it a system that detects when they actually fail or is it an inspection process?

Eric Binet – Technip (Presenter). In fact the target for this acoustic emission system is to detect failures in critical areas which are either at the top end of riser where we have higher loads. It could be tension, tension variation, tension and bending variations in the most dynamic zone. So we are for the time being working on the detection of breaks of the armours due to tension variation and later pursue detection on the dynamic zone of the riser. We have a process ongoing to qualify the first part of the application and then we will move on another application. But the purpose is really to detect the first breaks of the armours.

Douglas Souden – HSE (Seminar Chairman). I really personally believe that the interface issue is a strong one - with the evidence we see from a lot of incidents suggests that there’s a lot of hand-offs that don’t get picked up. Was there anything fundamentally different you did in this example you presented to us? Is there, you know, something you could specifically say was a good experience?

Eric Binet – Technip (Presenter). In fact the message I would like just to pass is that monitoring already is in place for many of the, or most of, the feeds in operations. But monitoring of the system is not enough. You can have good information but you need to have a proper system that analyse them. So in the past we have been involved in some issues on flexible pipes where in fact there was clear indication during the lifetime of the product that there was something going wrong. There had been some decisions taken to fix small problems that have led to other problems later on and the root cause of that for me is that there was no proper RIM system in place. Where someone had a competent overview of the system and is able to guide, to say well we should involve: the manufacturer - or we should involve maybe the hardware or software suppliers - or we should involve the client, to understand what really is going on and I think the key point in this monitoring issue is that we may develop stuff, we may develop technology but we need someone to take care of all the information and gather that into a system which is comprehensive for everybody.
