Muscat – The Environment Authority (EA) plans to establish a 3D-printed underwater museum in the Daymaniyat Islands Nature Reserve, using artificial reef structures to protect marine biodiversity and promote sustainable ecotourism, an official stated.

The project is part of wider efforts to enhance sustainability of the sultanate’s marine environment while ensuring development in ecologically sensitive areas remains aligned with conservation goals. A cooperation agreement has been signed with Omantel and Innotech to implement the initiative, which will be known as the ‘Underwater Landmarks of Oman Museum’, the official told Muscat Daily.

The first phase will be developed across 400sqm inside the Daymaniyat Islands Nature Reserve, one of Oman’s most important protected marine sites, known for its biodiversity and strict environmental safeguards.

At the core of the project is the use of 3D concrete printing technology to create environmentally friendly structures designed to support coral growth and marine life. The printed structures will be shaped to reflect well-known Omani architectural landmarks, including Royal Opera House Muscat and Al Alam Palace, transforming the site into an open underwater exhibition that blends environmental, cultural and tourism elements.

The initial phase is expected to include four main units. Innotech will be responsible for the technical and engineering implementation, in line with environmental standards and regulations governing the reserve.

According to the official, the materials used in the 3D-printed structures have been formulated to encourage the attachment of microorganisms and accelerate coral development. This is intended to increase their effectiveness as alternative marine habitats and support rehabilitation of the surrounding marine environment.

“The museum represents a national initiative that applies innovation and technology to protect the marine environment and promote biodiversity,” the official said, adding that partnership with the private sector reflects a shared commitment to preserving Oman’s natural heritage for future generations.

The underwater museum is expected to serve scientific and educational purposes in addition to attracting diving enthusiasts. It will provide opportunities for researchers and university students to study marine ecosystems and artificial reefs, and may host awareness programmes for divers on responsible behaviour and conservation.

Implementation of the first phase is expected to take between five and six months, depending on sea conditions, with completion planned before the end of the year. Following completion, environmental and technical assessments will be conducted to measure the impact on marine life and effectiveness of the structures.

Based on assessment results, a second phase will be launched, adding more 3D-printed structures inspired by Omani historical and cultural landmarks. The project is expected to ease pressure on natural diving sites, attract ecotourism and raise public awareness on marine conservation in the sultanate.
