NorwegianVision: Products and knowledge providing protection and life support for the sea
Taking Responsibility for the Marine Environment
by Offering Protection of Marine Installations, Resources and from Beach Erosion
Reef Systems as
The SeaCult concept is own by Reef Systems as. Reef Systems is a Scandinavian company who operates world wide. Their head office is located in Tønsberg Norway. The company was established during 2002 to deliver products, artficial reefs which can improve the growth conditions for fish, shellfish and other forms of nature on the seabed and in freshwater. Hence, we deliver products which can enhance aquatic biodiversity. We also deliver products which hinder erosion and protect undersea pipes and cables. Together with national and international organizations, we aim at providing leading technical knowledge about the involved subjects.
Background
Scientists state that the situation in the sea is an ecological catastrophe. Along the coasts worldwide enormous parts of the sea-bed have become virtually devoid of life. A huge man-made environmental problem is developing. Unsustainable human activities have resulted in over-exploitation, pollution and climate change that have reduced dramatically the natural vegetation, fish stocks and other marine biodiversity
Very good results in Hammerfest
During the summer of 2006 twentyfour Runde Habitat was placed nearby Hammerfest, Norway. The results after close to a year are very uplifting, which is what are shown in this video from NRK (the Norwegian Broadcasting Corporation) from June 19., 2007:Test reports from projects
in Risor and Trondheim Norway and Dubai UAE
Test report from Risor
Summary
High densities of fish established quickly (days), and attached organisms were established after a few weeks. After the first years, the reefs now support a community of macro algae, invertebrates and fish that is clearly richer than the surrounding bottom area.

PDFTest report from Trondheim
from SINTEF Coast and Harbour Research Laboratory by Arne Erling Lothe
Summary
The tests show that the Grip has a proven ability to create a lee-zone in steady current, which will cause a break in the transport of bed load and near-bottom sediment flows. The reefs are expected to be efficient against local erosion. Structures that are located inside the lee-zone will experience a significant reduction in bottom shear stresses and consequently have less erosion around them.

Test report from Dubai UAE
Runde habitat and fish place 2005 – 2007 by Prof. Chris Hopkins,
Aquamarine Advisers, Sweden
Abstract from the main conclusions test project are
The reefs within six months of their initial deployment had already demonstrated their ability to form an impressively good habitat for colonization of a wide range of species of sessile benthic organisms, including corals, molluscs (e.g. shellfish crustaceans such as crabs, pectinid bivalves, and nudibranch gastropods), sea squirts, barnacles and anemones. Additionally, many species of fish—several of which are otherwise almost exclusively associated with natural biogenic (e.g. coral) reefs—were clearly attracted by the reefs for foraging and refuge. Up to the present time (i.e. 26 months since the project start), this positive impression has been further strengthened.
