We are designers and engineers.
We are specialists… with water.
With creative and technical expertise, Oceanis brings water-based projects to life by helping our clients and partners create exceptional aquatic experiences.
Oceanis International is an aquatic engineering and design consultancy specialising in aquariums, aquatic centres, marine research facilities, and water-based developments worldwide.
Planning and Design Services for Water-Based Facilities
With more than 400 projects delivered worldwide, Oceanis International brings contemporary design thinking to water-based developments, informed by current aquatics research, environmental responsibility, sustainable practice, and operational expertise.
Our collective experience allows us to identify the real and current operational and capital costs associated with aquatic projects. We bring this know-how to our planning services, feasibility studies, and detailed cost analysis.
It takes experience to balance creative design with technical and economic realities.
Our multi-disciplinary team has a 25-year track record in designing water environments: leisure and resort facilities, wellness centres, pools, zoos, aquariums, large-scale mixed-use integrated attractions, and cultural and science facilities of every scale.
Why work with Oceanis
Having completed over 400 projects worldwide, we bring contemporary design to water-based entertainment, along with the latest in aquatics research, environmental and sustainable practices, and management and operations to our work.
Global Project Portfolio
Our global project portfolio spans aquatic centres, aquariums, marine research facilities, specialty pools, geothermal heating systems, aquaculture facilities, and zoological habitats, each designed to respond to the specific operational, environmental, and location-based demands of the project.
