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.

UAC can offer marine CNG storage and transportation units with a pressure of 150 to 250/325 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. This solution is currently under development and will be constructed according to governing rules and regulations, including ship classifications.

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 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 sail distances. It is assumed that CNG would be most competitive in emerging coastal markets, in interregional areas, where pipelines are either uneconomical or technically challenging, and in island states with strong governmental support for economical and/or environmental developments.

The potential for CNG ship technology is mainly in the transportation of natural gas as cargo between the source, such as production filed or gas grid, and markets, whether domestic or regional, with maximum distances of up to 1,500 – 2,000 nautical miles.

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 legislations 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 requirement.

UAC recognizes the importance of cost-efficient solutions that would offer added value to our customers’ operations in terms of compliance with ever more demanding industry standards and efforts to reduce environmental footprint across the supply chain. Therefore, we are involved in several national and international R&D projects that focus to explore implementation of alternative energy sources.

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