SB-LWS-2025-07 Gearbox oil viscosity grade change for LT-32 CCV turbines

FICTIONAL SAMPLE - Contoso Renewables, Quellmoor Ridge Wind Farm and every organisation, person, product and value in this wiki are invented. Not for operational use.

SB-LWS-2025-07 is a service bulletin for LT-32 CCV turbines covering gearbox oil viscosity grade.¹² It changes the gearbox oil from Proseware PWG 320 (ISO VG 320) to Proseware PWG 220 (ISO VG 220).³⁴ The bulletin applies to all 12 CCV turbines at Quellmoor Ridge.³²

Facts

• The change replaces Proseware PWG 320 (ISO VG 320) with Proseware PWG 220 (ISO VG 220) in the gearboxes of all 12 turbines, as required by SB-LWS-2025-07 Rev. A.³
• Litware support confirmed on 2025-05-20 under ticket LWS-TS-48213 that SB-LWS-2025-07 applies to all 12 CCV turbines of Quellmoor Ridge.³
• Revision B supersedes SOP-GBX-010 Rev. A and implements MOC-2025-012 and SB-LWS-2025-07 Rev. A.⁵
• Revision B changed the oil to PWG 220 per MOC-2025-012 and SB-LWS-2025-07, added the flush step, and set a minimum start-up temperature of +5 °C.⁶
• WTG-09 has gearbox oil conversion to PWG 220 pending and deferred under SB-LWS-2025-07.⁷
• Since SB-LWS-2025-07, the gearboxes use Proseware PWG 220 with ISO VG 220 instead of PWG 320.⁴
• The email was sent on 20 May 2025 with the subject “RE: [LWS-TS-48213] Applicability of SB-LWS-2025-07 to Quellmoor Ridge.”⁸
• Litware’s response addresses a 29 April 2025 question about SB-LWS-2025-07 Rev. A, described as covering gearbox oil viscosity grade for CCV turbines.¹
• The configuration records checked for Quellmoor Ridge Wind Farm showed that all 12 turbines, WTG-01 through WTG-12, were delivered as LT-32 in CCV configuration with Fabrikam FGT-3200 gearboxes, so SB-LWS-2025-07 applies to all 12 turbines.²
• The original requester asked whether SB-LWS-2025-07 applies to all Quellmoor Ridge turbines and whether the conversion could be done during the autumn maintenance campaign.⁹
