Ocean Rainforest was founded October 10 2007. In 2009 Ocean Rainforest obtained the licence for pilot testing close to a salmon farming operation in collaboration with Viking Salmon, which later was merged with Bakkafrost.
In March 2010 the cultivation rig was ready for deployment at the aquaculture test site north of the village Funningur in the Faroe Islands. The installation deployed had 1200 meters of seed line attached. During the following months the installation withstood winds up to 62 m/s and wave heights of 7.8 meters. The structure remains intact, undamaged in the water where it was deployed and has proven itself able to withstand the physical strains caused by an energetic wave climate and the storms of the North Atlantic.
In June 2012 NORA awarded a grant to the project MacroBiotech, which is planned to run for 2 years with a budget of 2.5 million DKK. The project co-ordinator is Ocean Rainforest and project partners are from Denmark, Norway, Iceland, Faroe Islands and Scotland. The main purpose of the project is to demonstrate the technical and commercial viability of the MACR concept for cultivating macroalgae in the open ocean. Seaweed harvesting methods will be developed and tested to demonstrate production capability and to ensure that the farmed product can be stored in a stable manner before it is shipped to the end user for processing.
In March 2013 biological tests commenced. Ocean Rainforest carried out a “cultivation test” and seeded line deployment. Ocean Rainforest is today (2018) the single largest macroalgae cultivation activity in Europe and North America and the largest in the world deployed in an open sea environments with >50 water depth.

Ocean Rainforest have  conducted up to three  harvests on the same line in the period from April to October. The species harvested are S. latissima, A. esculenta. L. digitara, P. palmata and L. hyperborea.  The average harvest yield on the lines have been among the highest known in Europe - up to 20 kg/meter wet weight per harvest.
