Common failures & inspection points

SFOC plausibility: long-stroke 4-stroke (A-series ~181–195 g/kWh) versus 2-stroke slow-speed (UEC ~152–200 g/kWh) — SFOC values not available for all models in public

Cross-reference manufacturer datasheets with IMO databases and classification societies (DNV GL, Lloyd's Register, ABS) for missing SFOC values

Model designations: AT33/AT33L documented in manuals, but not listed on current manufacturer website as active product line — could be obsolete

Check production years and availability from authorized dealers (ROTRENZA, Jenny Marine, XMH Holdings); inquire about manufacturing date and current delivery capability

UEC licenses: All UEC engines are Mitsubishi Heavy Industries designs, licensed to Akasaka/Japan Engine Corporation — verify license rights and production

Check type approval certificates (DNV, ABS, BV) and confirm production location; review Mitsubishi MHI documentation as primary source

Hilfsmotoren / Gensets: Keine detaillierten Genset-Spezifikationen in öffentlichen Quellen gefunden - Akasaka produziert laut Herstellerbeschreibung Hilfsmotore

Contact Akasaka directly at https://www.akasaka-diesel.jp/en-us/ or authorized distributors regarding auxiliary/genset product range and datasheets

K26S, E-type, DM-38, DM-46: reality confirmed (in service manuals, ROTRENZA catalogues), but specification data partially incomplete or only in proprietary

Request original manuals, maintenance manuals and technical drawings from authorized service partners; check ship databases (AIS, Equasis) for engine installation verification
