Proseware PWG 220

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

Proseware PWG 220 is an ISO VG 220 gearbox oil used in the gearboxes of Quellmoor Ridge wind turbines.¹²³ It replaced Proseware PWG 320 in the turbine gearboxes under SB-LWS-2025-07 and MOC-2025-012.^{41567891011121314151617} The oil-change procedure uses 60 L for flushing and 410 L for filling, and top-up is with PWG 220 only.^18192021223

Facts

• For affected turbines, the gear oil changes from Proseware PWG 320 to Proseware PWG 220.⁴
• The gearbox must be flushed with 60 L of PWG 220, the electric oil pump run for 30 minutes, and the flush oil then drained.⁴
• The gearbox must be filled with 410 L of PWG 220 through a filter cart with a 10 micron element.⁴
• The gearbox filler must be labelled 'PWG 220' using the supplied label kit.⁴
• Per turbine, parts and labour include 470 L of Proseware PWG 220, one FGT-P-11872 oil filter element, one PWG 220 label kit, and labour by 2 technicians for about 6 hours.²³
• 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.¹
• Action 2 is to order 36 drums of PWG 220 and set the minimum stock of PWS-220-D208 to 8 drums, owned by Tomasz Lebrecht and due 2025-08-15.²⁴
• The estimated cost is EUR 58,600 for 36 drums of PWG 220, 12 filter elements, labour, and waste-oil disposal, within the 2025 maintenance budget.²⁵
• The lubricant is Proseware PWG 220, ISO VG 220, in service since 2025-10-15.²
• The report states that viscosity and water content are normal for PWG 220.²
• The trend table shows the 2026-06-10 sample as PWG 220 oil with Fe 64 ppm, PQ index 112, viscosity at 40 °C of 229, and ALERT status.²⁶
• Each turbine requires 470 L of Proseware PWG 220, consisting of 60 L for flushing and 410 L for filling, supplied as 3 drums of PWS-220-D208.¹⁸
• Required tools include a torque wrench with a 20 to 300 Nm range, oil sample bottles, and a PWG 220 label kit.²⁷
• The flush step uses 60 L of PWG 220, runs the electric oil pump for 30 minutes, and then drains the flush oil into waste containers.¹⁹
• The gearbox is filled with 410 L of Proseware PWG 220 through a 10 micron filter cart.²⁰
• After 20 minutes of standstill, the oil level is checked at the sight glass according to SPL-012 and topped up only with PWG 220.²¹
• Controller parameter GBX_TMIN_START must be set to 5 °C, and the gearbox filler must be labelled PWG 220.²⁸
• 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.⁵
• WTG-09 has gearbox oil conversion to PWG 220 pending and deferred under SB-LWS-2025-07.²⁹
• Gearbox oil change task MP-GBX-03 for PWG 220 is scheduled every 5 years or on condition, references SOP-GBX-010 Rev. B, has a duration field of 6 h, and notes that the next planned changes start from 2030.³⁰
• WTG-07 oil sampling report TR-OA-2026-0614 recorded PWG 220 oil, Fe of 64 ppm, PQ index of 112, condition ALERT, and next sample due 2026-07-10 with resampling within 30 days.³¹
• Issue 1 was issued on 2025-12-15 and updated the oil sampling schedule for PWG 220 under MOC-2025-012 action 5.³²
• Top-up is only permitted with PWG 220 through the 10 micron filter cart, and PWG 320 must not be used.²²
• The export records a completed high-priority modification campaign for gearbox oil conversion from PWG 320 to PWG 220 with a 60 L flush for WTG-01 through WTG-12 under reference MOC-2025-012; each row lists part PWS-220-D208 with quantity 3.^{67891011121314151617}
• Since SB-LWS-2025-07, the gearboxes use Proseware PWG 220 with ISO VG 220 instead of PWG 320.³
• Oils must not be mixed; top-up is with PWG 220 only.³
• The quiz answers state that the HSS drives the generator, A2102 trips at 82 °C, the oil used is Proseware PWG 220, and a rising PQ index means more ferrous wear debris, often from a bearing.³³
• For the conversion, the oil is to be changed from Proseware PWG 320 to Proseware PWG 220 at the next scheduled oil change, and no later than 31 December 2025.³⁴
• Each gearbox is to be flushed with 60 L of PWG 220 before the final fill of 410 L.³⁵
• After switching from PWG 320 to PWG 220, oil filter element FGT-P-11872 is to be changed a second time after 500 operating hours because loosened deposits collect in the filter.³⁶
• PWG 220 conversion status was: nine turbines completed, WTG-11 being converted that day, WTG-12 scheduled for the following Wednesday, and WTG-09 planned for the twenty-fourth if the access road remained open.³⁷³⁸
• With PWG 220, the minimum oil temperature for start-up is plus five degrees; with the old PWG 320, it was plus ten.³⁹
