Competitive alternative for any application.

UAC can deliver type IV pressure vessels both as containment systems onboard ships and for purpose of transportation of natural gas as cargo onboard container vessels. We can also supply pressure vessels for transportation of CO2.

We offer marine CNG storage and transportation units with a pressure of 300 bar – by design, using a containerized solution or independent tanks, fixed by a cradle to the tank top. Larger containment volumes may be accommodated by design of larger modules, both in diameter and in length.

When evaluating alternative CNG storage systems in marine environments, corrosion often is considered a decisive factor. UAC pressure vessels are built in a non-corrosive, non-toxic composite, lined with a high-density polyethylene.

Further advantages of UAC glass fiber pressure vessels include weight savings, temperature tolerances, long-term design life and enhanced safety levels, compared to pressure vessels of steel and of those built in other composite materials. Glass fiber pressure vessels are also a much more price competitive alternative compared to carbon fiber.

CNG storage and transportation.

Transporting compressed natural gas requires an assessment of the ideal pressure and temperature in order to optimize the CNG ships and the value chain. Generally, higher pressure and lower temperature offer a higher gas density, influencing containment volume and ship size.

Marine CNG will be able to fill the gap for small and medium volumes, and short and intermediate sailing distances. It is assumed that CNG would be most competitive in emerging coastal markets, in inter-regional areas, where pipelines are either uneconomical or technically challenging, and in island states with strong governmental support for economical and/or environmental developments.

CNG and hydrogen as fuel onboard ships.

CNG and hydrogen can be used as fuel when gas infrastructure is available and sailing distances can be accommodated for regional trade and inland waterways. We have delivered a container-based fuel storage system for a day ferry.

Introduction of stricter local, national and international environmental legislation demands cleaner solutions for fuels within the maritime industry. Use of natural gas for propulsion and electric power generation onboard is viable solution in meeting the reduced emission requirements.

UAC recognizes the importance of cost-efficient solutions that offer added value to our customers’ operations in terms of compliance with evermore demanding industry standards and efforts to reduce environmental footprint across the supply chain.

We  deliver tailored solutions to customer requirements and industry regulations with class approvals by DNV-GL, ABS and Lloyds Register.
