HE-O / Offshore helium solutions
Diving gases, testing, subsea work and offshore commissioning begin with different gas, handling, analysis and replenishment requirements. The selected asset and certification route are confirmed project by project.

Solution routes
The project route determines the required gas, identification, analysis, pressure, frame, documentation and replenishment plan.
Commercial diving, heliox and trimix requirements, and saturation-diving support planned around the approved gas specification.
Surface gas supply and handling evaluated around subsea welding, cutting, inspection, repair and maintenance work.
Pressure, flow, consumption and delivery are defined by the approved leak-test or commissioning procedure.
Offshore project supply
A technically correct gas requirement can still fail operationally if the asset, port-call transfer, acceptance checks or reserve plan are left undefined.
Offshore pack references
Official supplier pages show 16-, 48- and 64-cylinder formats. Counts, pressure and frame layout remain examples rather than Lesoo specifications.
| Reference format | Published supplier example | Pressure | Dimensions / manifold | Status |
|---|---|---|---|---|
| 16-cylinder quad | 16 × 50 L / 13.2 US gal water capacity per cylinder | 300 bar / approx. 4,350 psi example | Confirmed by selected cylinder, frame, lifting set and outlet | Example configuration |
| 48-cylinder pack | One official offshore supplier lists this count among its typical pack sizes | Project-configured | Dimensions confirmed by configuration | Supplier example |
| 64-cylinder quad | 64 × 50 L / 13.2 US gal water capacity per cylinder | 300 bar / approx. 4,350 psi example | Confirmed by selected cylinder, frame, lifting set and outlet | Example configuration |
Configurations shown are representative industry references. Final gas grade, cylinder format, pressure, connection, certification and documentation are confirmed against the application, destination, volume and delivery plan. No frame shown on this page is represented as a certified Lesoo asset.
Documentation & safety
DNV-ST-E271 provides technical requirements and guidance for the approval and certification of offshore containers and lifting sets, including manufacturing, testing, marking and periodic inspection. A project can request that route, but the page itself cannot make an unassessed frame certified.
Review Lesoo quality information →HE-O4 / Oceanographic research
Oceanographic work can combine analytical, calibration, lifting, pressure or specialist gas requirements. It remains an application module on this family page until a verified product specification and independent project workflow are available.
Offshore helium questions
Published pack counts provide context. Project controls determine what can actually mobilise.
The page covers diving gas routes, subsea operations, testing and commissioning, and oceanographic research as project directions.
No. They are published supplier examples. The final cylinder count, pressure, frame, manifold, outlet and lifting arrangement are selected for the project.
No. Certification and inspection status belong to the selected physical asset and approval route. They must be verified for the project.
Provide the operation, gas or mixture, destination, expected consumption, pressure, preferred asset, mobilisation dates and required documentation.
