Unresolved points:
The technical table identifies ST-30 and 30 m depth, although the generic page teaser mentions 150 m. This summary follows the named table, not the teaser. One row repeats a speed label with a kN unit and is withheld. Confirm the installed drilling attachment, circulation equipment and sample / core tooling; the model title alone does not prove wireline capability.
