Hola a todos
Diego has informed that the main transformer is leaking oil, meaning that it could fail anytime.
NOAO S is contacting the company that made the transformer to request the presence of one of their technicians on Pachon ASAP to evaluate the severity of the situation. At the moment we don't know when would be the earliest this person would arrive on site.
In parallel FINNING is finishing up the maintenance of our generator, expecting to be ready to fire it up around 3 PM today.
Diego anticipating major problems has already contacted the company we are renting the second generator from, so they allow us to keep it for few more days until the emergency is over.
Today we had a meeting to elaborate a contingency plan in case for whatever reason we have a power loss.
The contingency plan covers the following scenarios.
We lose power between now and the time our generator is back in business.
Actions
We switch to back up generator
We re organize our loads to assure power to instruments and computer room
No operations at night
A crew of at least 2 persons stays at night to look after the site and the generator itself including refilling fuel.
TTM is contacted, IS is contacted, E&IG is contacted, Site is contacted, QC is contacted, Head of Science operations is contacted, SOS manager is contacted.
We lose power tonight, our generator already repaired and tested for few hours kicks in.
Actions
We will switch automatically to our generator as usual.
A crew of at least 2 persons will come up to look after the site and the generator, getting ready for an emergency transfer in the event our generator fails.
We operate at night with the restrictions of being on generator power.

Other scenarios
Nothing happens over the weekend, the transformer still news to be serviced. This will be done during the day. For that particular night we will evaluate if it is recommended to leave a crew behind at night.
Nothing happens tonight, our generator will be tested tomorrow during the day for several hours using the dummy load.
Nothing happens and the generator maintenance is finished around 3 PM, we will test the generator tonight and tomorrow. Tonight we will test it until 10 PM.
Nothing happens tonight but the oil level on the transformer is dangerously low, we will evaluate if it is advisable to transfer the load to our generator after it has been tested tomorrow, plus turning transformer off.
Main Roles already defined.
Diego is our single point of contact with NOAO S
Gustavo will make sure the whole plan is properly coordinated and resourced
Rolando looks after instruments, technical advisor
Paul supports NOAO S and our electrician, including night shifts
