VLCC and ULCC Operators Ranked on Garden Data

Oil majors vet tanker operators on dozens of criteria, but bridge-team circadian health has been invisible to the scorecard. Garden-data rankings surface the missing dimension and reshape how charterers assess operator quality.

The charterer's vetting lead had run tanker operator scorecards for seventeen years. She had access to OCIMF SIRE 2.0 findings, TMSA self-assessments, Clarksons operator data, EMSA casualty records, and a custom internal rating her firm maintained on top of all of that. What she did not have, and what she had started asking for in 2025, was any data on the actual physiological state of the bridge teams her cargoes were being carried by. The safety case on a VLCC is made in the wheelhouse at 0315 local on voyage day nine, not in the audit report shelved six months later.
