In about 2000, DNV came up with the idea to use steel concrete sandwich (SCS) as construction material for marine vessels. Since then, DNV has been working to explore the possibilities and potential for the SCS concept together with a large shipyard group and other industrial partners. Now the relevant patents have been released, and DNV hopes this will lead to innovation in the area.
"We want to make the technology available for the industry, and by releasing some of our ideas and studies we hope this initiative can foster open innovation around using new materials in ships and offshore structures," says CEO of DNV, Henrik Madsen.
DNV is prepared to assist the industry and has deep competence in both concrete and sandwich theory, and can contribute with development and qualification of such technology. In order to give a brief introduction to the technology, DNV Research and Innovation has made a white paper (download available on right hand side) in addition to a report from a technical study. The Offshore Standard for Offshore Concrete Structures (DNV OS C-502) can also be downloaded by following a link in the right hand column.
"DNV made the decision to release the patents held for the sake of industry benefit as the basic technology now is available for all partners and stakeholders in the industry," says Hans Ramsvik. He continues; "We are eager to see how the use of such sandwich material can be utilized by the leading companies in the future."
"Please don’t hesitate to contact us for discussions and assistance," says Hege Berg Thurmann, Head of Concrete Structures and Dag McGeorge, Global Service Director for Technology Qualification.
The original idea for a steel sandwich construction using light-weight concrete came from DNV Research and Innovation.
