We completed the hydrotesting of JP-5 and Diesel pipelines and piping on Kodiak Coast Guard base this week. This’s the second time Winsor Construction and Enterprise Engineering have performed the 5 year hydrostatic, or pressure, test at US Coast Guard Station Kodiak. Last test was in…you guessed it…2010.
Kodiak is a fun place to work
Another good project where we work for Enterprise Engineering as a subcontractor. With another good Enterprise on-site test engineer, Travis, easy to work with and work for.
Enterprise wrote an IMP (Integrity Management Plan) for all POL systems on the base. The Integrity Management Plan details the layout of all piping systems into segments, the distances and capacities, which valves to test against, how often to pressure test and the test pressure, and which regulations or jurisdiction each segment falls under – USCG, ADEC, API, etc. The IMP makes planning for these hydrotests much easier than without an IMP (written test plan). I have to write it once more, IMP. Ahhh, I feel better now. And again…IMP.
Over the two weeks on island, we tested 11 piping segments. The segments comprised about 17,000 feet and 31,000 gallons of JP-5 or Diesel. Kodiak Coast Guard station is a relatively small, or compact, base. The piping to the old Navy cut & cover tanks would double piping lengths, but tanks and piping were abandoned when the Navy pulled out and converted the area to a Coast Guard station.
A couple of the piping segments were tested twice due to temperature and pressures not correlating properly. The weather was very un-Kodiak like during the daytime (it was hot n sunny), so segments with aboveground piping were tested late at night into the wee hours when temperatures stabilized somewhat.
At the end of the project, another local working on Kodiak base drove our pickup onto the ferry. Then I flew down to Homer, drove the truck off the boat when it arrived thirteen hours later, and drove it back to Eagle River. And he left a mason jar of homemade (home distilled?) whiskey in the cab. I only “sampled”, I didn’t “drink”. It was a beautiful sunny day on the drive home.
