Offshore DNV Cylinder Racks
A DNV cylinder rack is also called an offshore gas bottle rack or offshore cylinder basket. It is a certified steel frame built to safely store and transport pressurised gas cylinders in offshore and marine environments. Al Muftah International supplies DNV 2.7-1 certified cylinder racks in 4 to 24-cylinder configurations across the GCC, Middle East, and internationally backed by current certificates, ADNOC and Saudi Aramco approvals, and full recertification support from our Sharjah engineering facility.

What is a DNV Cylinder Rack and Why the Certification Matters the Most
A DNV cylinder rack is not simply a storage frame for gas cylinders. It is a certified offshore lifting container engineered and tested to handle the forces of crane lifts between supply vessels and platforms, open-sea deck operations, and FPSO gas transfers.
The DNV 2.7-1 certification is what separates a rack that can legally be crane-lifted ship-to-rig in the Arabian Gulf or North Sea from one that cannot. Without a current, valid DNV 2.7-1 certificate, a cylinder rack cannot be used in any offshore crane lifting operation. The certificate specifies the Safe Working Load, dynamic test results, rack serial number, surveyor identity, and expiry date.
In practice, it is the first document an offshore procurement officer checks before dimensions, before price, before lead time. If it isn't immediately downloadable from the supplier's page, most buyers move on. Al Muftah International supplies DNV 2.7-1 certified gas bottle racks with current certificates available for immediate download — rack serial, DNV surveyor name, issue date, and expiry date all visible before any enquiry is raised.

Who Al Muftah Supplies DNV Cylinder Racks To
DNV 2.7-1 Certified Gas Bottle Racks for Offshore Oil and Gas - ADNOC, Saudi Aramco, and Major Operator Approved
Al Muftah's DNV 2.7-1 certified cylinder racks carry explicit ADNOC and Saudi Aramco approvals listed on the product documentation.
Offshore procurement teams typically search for very specific configurations before placing any order — a 16-cylinder rack with sling set, forklift pockets with crane pad eyes, or stackable racks for FPSOs where deck space drives every equipment decision. Al Muftah's racks are built to answer all three: certified sling set and shackles included, forklift pocket dimensions and crane pad eye SWL fully documented, and stacking configurations available for FPSO deployments.
What makes an offshore oil and gas buyer choose Al Muftah
- Sling set and shackles included - certified lifting gear supplied with rack, not as a separate line item
- Urgent replacement and rental - expired or damaged rack situations resolved without offshore gas supply gap
- Full dimensions and SWL documented - deck planners get OD, height, tare weight, and max gross mass upfront
- Manifolded rack configurations - O2, N2, Ar, He/O2 manifolded cylinder packs, DNV certified
Offshore Gas Bottle Racks for Marine Operations - EN 12079-1, IMO MSC/Circ.860, and DNV Certified
A vessel manager sourcing offshore gas cylinder containers needs more than DNV 2.7-1 — they need IMO MSC/Circ.860 compliance for open-sea handling, and often EN 12079-1 or ISO 10855-1 for EU-flagged vessels or tenders from European operators. Al Muftah's offshore cylinder baskets are certified to all three standards where required, with the full compliance documentation available as a single package.
Shipyard procurement teams running drydock gas supply operations face a different challenge entirely: high-volume, short-duration use of cylinder racks during steel cutting, welding, and blasting. Al Muftah's rental pool solves this directly. DNV 2.7-1 certified gas bottle racks are available for the duration of the drydock, with full certification documentation for the shipyard's safety file.
What makes a marine and shipyard buyer choose Al Muftah
- Rental pool for drydock operations - certified racks available for short-duration use, no idle capital asset problem
- Hot-dip galvanised with documented thickness - 85-micron minimum coating spec in the certificate, not estimated
- −40°C design temperature certified - North Sea and cold-climate operations fully covered by base specification
- Full safety file documentation - everything a shipyard HSE department needs in one package, one supplier
DNV Certified Gas Cylinder Racks for Industrial and Shore-Based Operations
Steel plants, shipbuilding yards, and heavy fabrication operations run into a common problem: racks that have been in service for several years and fail their 48-month structural inspection — sometimes weld degradation, corroded pad eye attachments, damaged forklift pockets. At that point, the rack is grounded until it is recertified or replaced.
Al Muftah's recertification service covers the full process — structural assessment, repairs to restore DNV certification, and a complete inspection report documented for the client's safety file. Where repair isn't viable, we advise on replacement with the same turnaround focus, so the rack is back in service rather than sitting in a queue.
What makes an industrial buyer choose Al Muftah
- Offshore-grade cert for shore-based crane lifts - DNV 2.7-1 required for certified crane operations regardless of location
- Failed recertification repair service - AMI assesses, repairs, and recertifies rather than defaulting to replacement
- Painted and galvanised from same design - one supplier for both corrosion protection specifications
- Lead time confirmed upfront - offshore projects and industrial shutdowns can't wait 10 weeks for a delivery estimate
What Every DNV Cylinder Rack Buyer Needs — And How AMI Delivers It
Certificate First, Speed Second
The DNV 2.7-1 certificate is the first document an offshore procurement officer checks — before dimensions, before price, before lead time. AMI's current certificates with rack serial, issue date, and expiry are sent in downloadable format when an enquiry is raised.
Lead Time Transparency
Offshore projects don't allow for second chances. AMI confirms delivery windows and confirmed availability upfront for urgent offshore cylinder rack requirements — no 10-week estimate given after the purchase order.
Full Dimensions & Weight
Dimensions, height, tare weight, and maximum gross mass are confirmed upfront for every 4, 6, 8, 12, 16, and 24-cylinder configuration — deck planners get what they need before any purchase commitment.
Recertification Clarity
Long-term total cost of ownership depends on recertification costs and timelines. AMI documents the scope and estimated cost of both the 12-month inspection and the 48-month full structural recertification at the point of purchase.
Customisation Options
4, 6, 8, 12, 16, and 24-cylinder configurations with manifolded rack options for O2, N2, Ar, and He/O2 diving gas. Forklift pockets, crane pad eyes, stacking frames, and painted or hot-dip galvanised finish all configurable to the offshore specification.
Operator Approvals Listed
If the rack is already approved by the buyer's operator, it removes a procurement bottleneck. AMI's ADNOC and Saudi Aramco approvals are listed explicitly on product documentation — confirmed before any enquiry, not submitted as a vendor qualification after.
Frequently Asked Questions: DNV Cylinder Racks from Al Muftah International
Does Al Muftah supply DNV 2.7-1 certified cylinder racks that are ADNOC approved?
Yes. Al Muftah's DNV 2.7-1 certified offshore cylinder racks carry ADNOC and Saudi Aramco operator approvals, named explicitly on the product documentation. This is confirmed before any enquiry is raised — not provided as a vendor qualification submission after the fact. For GCC offshore operations, pre-existing operator approval significantly compresses the procurement cycle.
How many cylinders fit in a DNV rack — 12 vs 16 cylinder configurations?
The answer depends on cylinder diameter and height. AMI supplies DNV offshore cylinder racks in 4, 6, 8, 12, 16, and 24-cylinder configurations. For standard 50-litre cylinders, 12 and 16-cylinder configurations are the most common offshore selection. For larger diameter cylinders (80-litre, diving gas), 12-cylinder configurations are typical. Our technical team provides free sizing guidance — footprint, tare weight, and maximum gross mass for every cylinder count and cylinder size combination, before any purchase commitment.
What does DNV 2.7-1 cylinder rack recertification cost and how long does it take?
Al Muftah documents the scope and estimated cost of both the 12-month DNV rack inspection and the 48-month full recertification at the point of purchase. Actual cost depends on rack condition at inspection. Lead time at our Sharjah facility is typically 5–10 working days for 12-month inspections and 10–20 working days for 48-month full structural recertifications.
Can Al Muftah provide offshore cylinder rack rental for urgent or short-term requirements?
Yes. AMI maintains a rental pool of DNV 2.7-1 certified cylinder racks for urgent replacement, expired-certificate cover, and short-duration offshore project requirements. Rental racks come with full current certification documentation, certified sling sets, and confirmed delivery timelines — no 10-week lead time.
Does Al Muftah supply manifolded DNV cylinder racks for offshore gas supply packs?
Yes. AMI supplies manifolded offshore cylinder racks certified to DNV 2.7-1 and DNV 2.7-3 including oxygen, nitrogen, argon, and helium/oxygen diving gas manifolded configurations. Manifold assembly, pressure regulation, gas service labelling, and certification documentation are all included. Free technical sizing for the specific gas service and offshore operating duration is available before purchase.
