3) Visual status check of Module 1 motors with Asadra (Karim).
4) Receipt of MLNG drawing BTU-40.009 (master single line diagram).
5) Receipt of MarelliMotori megger resistance acceptance criteria from vendor (FKI); 10Mohm for new motors, 1Mohm for old motors. (New motors for P-1105A/B tested at 3-8Mohm.)
6) Oven heating of P-1105A/B Marellimotori units at MLNG workshop. (Motors are 2.2kW 5.2A @ 50Hz, delta connection only.)

8) Inform Asadra & inspector on MLNG’s concern about motor uncoupled run delay. Ask why the delay is occurring.

10) Copy process description documents from Commissioning Engineer.
11) Follow-up on MLNG operations request to check PTS requirements for number of oil samples to be withdrawn from new drums.
12) Attend confined space entry HSE lecture.
13) Nitrogen filling of electrochlorination transformer #1 to reduce water ingress. (Note: transformer couldn’t be completely emptied via handpumping; i.e. the transformer oil containment base does not seem to be flat. Oil change vendor replied verbally the 200-250L old oil remaining on the transformer was not a concern because it is below the transformer core level. KBR supervisor also informed the new oil filtration shouldn’t be done at MLNG workshop but done next to the transformer while the oil is inside, using it as a breaker tank. New oil is easily contaminated during transport out to in back into drums. KBR supervisor also expressed concern the transformer’s original tapping setting was not marked by MLNG prior to removal. KBR supervisor did not approve the transformer oil change procedure for the above reasaons but was overridden by MLNG; his recommended practice was to facbricate a drain plug, drain, and cut off the transformer top head to perform a visual inspection of the core prior to rewelding back and filling with new oil & Nitrogen filling)

MRR Module 1 electrical progress:
-electrochlorination transformer "A" barricading and sheltering
-get Rustam's (Asadra) agreement to re-megger heat trace cables after piping insulation installation per Thermion installation guide
-buy USB flashdrive to copy large process description docs from Zul's (Commissioning) PC
-get master single line diagram of MLNG plant (A1 size) from Wan Aswandi / Jalil Bujang
-visit motor workshop to witness P-1105A/B 2.2kW motors being heated in oven to remove water (motors failed megger test for coils; only 3Mohm reading; MLNG3 spec is 15Mohm minimum)
-forward SG13course/leave application forms from Naomi/En Khazin to Buzz Shircliffe's desk
-exchange phone numbers with Chan (Rotary) for witnessing of dielectric test of old and new electrochlorination transformer oil at Sesco tomorrow.
-Boiler 5130 insulation has yet to be completely removed for heat tracing cable installation. Boiler 5120 heat tracing cables have been installed, meggered and are ready for piping insulation installation.
-Read up contract scope for HV switchgear modification at SS1 and 17 (AVR & UPS upgrade)

Zul is concerned on late construction handover to his commissioning team; he only has a month left to commission Module 1 but it hasn't been handed over from construction yet.

Conversation extract with Chika today:

"Adam-san, do you know what Salim did today."

"..No. Should I?"

(frowning) "No."

"Is there anything you'd like us to do?"

(shaking head) "No."

"Well, if there's anything you'd like us to do, let us know.."

(Terminator-style) "Have a nice day."
