Offshore Gases and Cylinders

Offshore: Gases and Cylinders

Across the offshore industry, the pressure is on. Against a backdrop of constantly changing regulations, our main focus is to ensure that essential gases and refrigerants are supplied, transported, stored and used safely in compliance with the latest regulations.
Published: (Wilhelmsen Ships Service, Marine products)

We operate the world’s largest global network of distribution, re-filling, maintenance and exchange of gas and refrigerant cylinders. In addition to this, we provide you with transportation racks and manifold racks for safe handling during transport/storage.

Transportation Racks & Cylinder/Rack Exchange

For safe handling, transport and storage of gas cylinder, we provide certified rental racks in compliance with DNV 2.7-1. Each rack holds X16 cylinders and both rack and cylinder are barcoded for tracking. WSS also facilitate the required 3rd party rack inspection every 12 and 48 month. The rack can be equipped with an IMDG certified manifold with a single central outlet. The latter feature is optional and available up on request. With respect to the Unitor™ cylinders, we ensure the quality through a continuous and rigid maintenance and quality assurance program. We track and trace each individual cylinder through barcodes and offer a worldwide cylinder exchange program. Send us your empty cylinders and we will swap them with pre-filled new cylinders at your convenience. If desired, and preferable with respect to safe handling, an equal exchange of cylinders should be practiced by using our transport racks. Consolidation of your gases and rack supply creates savings through a single procurement process, one logistic operation and the use of standardised high quality products.
