Dnv rack — offshore-ready gas cylinder frames
A DNV rack is a gas cylinder frame designed for offshore and marine lifting, where the structure must withstand crane handling, vibration and harsh sea conditions.
REAL GAZ supplies cylinder racks and bundles for such duties and helps coordinate the documentation your project requires.
REAL GAZ supplies cylinder racks and bundles for such duties and helps coordinate the documentation your project requires.
Frames are associated with DNV 2.7-1, EN 12079 and IMDG practice, with gas content under ADR / UN and ISO 10286 terminology.
DNV is a classification society whose offshore container standard, DNV 2.7-1, covers frames that are lifted by crane at sea. A frame for gas cylinders normally carries a nameplate, a unique identification number and periodic inspection records. REAL GAZ does not replace the certified fabricator; instead we fill, test and label the cylinders inside the frame and prepare the delivery documents. If your project needs a particular approval certificate, tell us early so that the correct frame, cylinders and paperwork are matched before the supply boat is scheduled. Colour coding, shoulder markings and clear labels allow deck crews to recognise the gas at once, which matters during night operations or when several racks are stored together on a supply boat.
🏭 Where DNV Gas Racks Are Used
- 🛢️ Offshore platforms — racks supply welding, calibration and instrument gases on production decks;
- 🚢 Marine vessels — ships carry shielding gases and mixed gases for maintenance work;
- 🏗️ Subsea projects — divers and ROV support teams use compact frames of breathing and inert gases;
- ⚡ Wind farm service — technicians transport gas for turbine repairs by vessel and helicopter.
📐 Typical Rack Features
- steel frame with lifting points rated for offshore crane use;
- cylinder retention straps that stop movement during transport;
- fork pockets and drainage for safe, flexible handling on deck.
