| Port Rigmar July 2006
Port Rigmar is the only jack-up type accommodation unit accepted and capable of working on the Norwegian continental shelf. This unit has a total bed capacity of 326. Port Rigmar was converted from drilling mode to accommodation mode in 1991 and has since then only worked in the North Sea.In July 2006 we supplied Syntho-Glass® for repair of a huge cooling-water pipe that had sprung leak. The pipe is in constant contact with seawater, and the repair was done in 30 minutes without shutdown.

| The CC office recently performed an unusual pipeline repair for Houston Pipeline Co. The leak was in the body of the 24" RTF 600 ANSI flange at the 3 o'clock position in a 3\4" grease injection port. Operating pressure for this line is 1250psi. Water depth is 90 FSW. The leak was propagating as time went by deciding how to make the repair. There are 20 clients elling through this trunkline and they all wanted it back on-line ASAP. John C. put us in contact with the SYNTHOGLASS representative (AL MARE) who provided us with recent DOT rocedures that allow for a simple repair to pipeline leaks. Basically, if you follow these procedures the repair is recognized as an approved repair by the DOT. We cleaned the area around the leak, applied a 2-part epoxy and wrapped the flange in SYNTHOGLASS the recommended number of times. We allowed 3 hours to set and began pressuring up the line. he repair held and is still in place. It is expected to be a permanent repair. The installation took one dive. The alternatives we all know Would be expensive and timesuming. This is an effective solution.

Subject: RE: Request for information
| Susan:
We have used Syntho Glass tape in many places (all have been under water applications):
In Raisers:
We've use it to repair very badly corroded ones and even some with holes in them. For the former ones we put a screw and in one opportunity even a piece of wood to patch the hole then used the tape to cover and re-instate the mechanical integrity of the riser. We have repaired approximately 5 risers including risers for flowlines and gathering lines. The ones with the hole were repaired back in Oct-Nov 1998, and so far we have had no problem whatsoever. The only condition was that I had to derate the flowlines to a maximum perating pressure (MAOP) of 200 psi, and increase the inspection frequency to every 9 months, instead of every 3 years, for a regular riser. The raiser for the gathering line was epaired in August 1999. This line carries 10 MBbls of crude oil. Also I derated it to a MAOP of 200 psi. For this particular one, the riser was also with a hole and badly corroded hroughout. If we would have replaced it completely it would have cost us approximately 200 MU$ plus the associated production loss equivalent to 3-4 days (30 - 40 MBbls).
On flowlines:
We have use it in two ways on for complete pipeline re-habilitation (mechanical integrity) and the other just for coating re-habilitation.
For pipeline re-habilitation: We had two flowlines that were also severely corroded with holes. For these wells we almost replace the hole line for a cost of about 500 MU$. But instead, after finding out about this tape, we use it in the places were the line was in worse shape and rehabilitated both lines and I think we only spend about 10 MU$. The wells are low producers so it did not justified the expenditure. This was again done back in Oct-Nov. 1998.
On Oil transmission lines (Oloeductos):
The lower elbow of the raiser of our main oil export line was without any coating and deep pits were developed in the line. This line carries all our production to a location onshore on the other side of the lake. This line was too repaired with the tape back in Feb 1999. In this case no derating was required since the RWT was enough for pressure and corrosion allowance. For all the above cases that we have used the tape, so far has not given us any problems. As I mentioned the only thing was pressure derating and increase in inspection requency.
Coating Repairs:
Also, for many of the damages caused by anchor wires, fishermen anchors, and others I am using the tape just to repair the polyethilene coating of our pipelines. We have found it
to be diver friendly, thus speedy job. For NACE Corrosion 2001 I am putting out a paper detailing every one of the pipeline and coating rehab we have performed.
