MARIN (Maritime Research Institute Netherlands) has tested an innovative concept for a floating mega island. The island comprises 87 large floating triangles that are connected to one another. Together they form a flexible floating island that can be as large as 1 to 5 km in cross-section.

Floating mega islands offer future-proof living and working space at sea for: developing, generating, storing and maintaining sustainable energy (offshore wind, tidal energy, wave energy and floating solar panels); loading and trans-shipping cargo in coastal areas where there is little infrastructure; cultivating food, such as seaweed and fish; and building houses and recreation close to the water.
