Part of Environmental Compliance
Keep statutory record books digitally: Annex I oil record book Part I with master countersign per Reg 17.6, Annex IV sewage, Annex V garbage across 11 categories (A-K), and Annex VI air emissions. Every entry is cryptographically chained to the one before it, so later changes are detected and identified in the PSC export.
