Lid down operations for 2019/2020 shutdown went ahead as planned on March 10th 2020 with Dan Louie and Arthur Leung absent due to a conference. Please see attached file for station counter numbers. Station two right side Highfield gear box was making intermittent growling from outboard bearing, this station is next on scheduled maintenance and will be inspected post removal next shutdown. Station 3 has spare jack set 13 in place, using Operations thermal camera we where able to observe higher than normal running temperatures from right side gear box. Upon removal next year we will investigate bearing end play tolerances as this is the suspected cause of heat. |
