Tank	Target Vol M³	After MT	Blended SG	Corr Sndg @ Trim 0.0m	Corr Sndg @ Trim 1.0m	Corr Sndg @ Trim 1.5m	Corr Sndg @ Trim 2.0m	Ullage @ T0.0	Ullage @ T1.0	Ullage @ T1.5	Ullage @ T2.0

⚠ Corr Sndg = sounding after applying trim correction (what calibration table uses). Ullage = Depth − Raw Sounding (what you read on the ullage tape — use this column). Use the column matching the vessel trim at time of completion. After MT = Target Vol × Blended SG (ROB at current SG + new fuel at BDN SG).

Active Grades:

VLSFO LSMGO

— tick the grades being received simultaneously. Each grade gets its own operation details, timeline, and progress tracker.

VESSEL CONDITION — BUNKERING

Trim changes during bunkering — update as needed. All soundings corrected using these values.
