Subject: centerline datum markings и apart with a transit. Как правильно перевести apart with a transit и centerline datum markings. Выражение встречается в следующем контексте:Plumbing & Verticality The equipment shall be inspected visually from two directions, 90 degrees apart with a transit. The Surveyor shall sight the top, middle and bottom of the vessel shell to ascertain if it is plumb. Very tall equipments shall be checked for verticality early in the morning. Reference points shall primarily be centerline datum markings of the vessel. A side profile reading may be may be taken in some cases. Заранее спасибо |
