Eight weeks of uninterrupted LOTUS Beacon data on TORM Kirsten’s main engine showed progressive but controlled oil aging — viscosity ratio climbing from 1.00 to 1.65, moisture flagged from Week 3, TBN healthy throughout. A single lab result showing viscosity at 165 cSt might have triggered an oil change. Continuous trend data made clear it…

Water saturation hit 28% and moisture reached 1,811 ppm on day one of LOTUS Beacon monitoring aboard MV Shahrastani — a Petredec LPG carrier already fitted with ACONIS. The contamination was tracked daily, the purification response validated in near-real time, and zero wear debris detected throughout. Pilot completed; fleet scale-up confirmed.
LOTUS Beacon flagged water saturation at 3.5× the acceptable limit on a main engine crankcase — sustained over a week, not a spike. The Chief Engineer acted, purifiers were overhauled, and post-treatment data confirmed full recovery. A $10,000 sump oil changeover was avoided entirely.
