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 and marine design and engineering consultancy specialising in aquariums, aquatic centres, marine research facilities, aquaculture, resorts and wellness developments, and water-based insfrastucture worldwide.
Planning and Design Services for Aquatic & Marine Facilities
With more than 400 projects delivered worldwide, we bring 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.
Oceanis International’s 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.
Global Project Portfolio
The Oceanis International portfolio documents 25+ years of water-based engineering across conditions that rarely repeat.
Projects range from the AIMS SeaSim National Sea Simulator in Queensland, independently recognised as one of the world's most technically complex marine research facilities, to geothermal rehabilitation projects, marine research and aquaculture facilities, aquatic centres, aquariums, and resort and wellness developments across Australia, Asia, the Middle East, North America, and the Pacific.
