C4R is founded by Bill Endersen in 2009.

Since 2001 a great variety of installations of sonar systems has been performed around the world. This includes design and fabrication of installation hardware from tiny mounts on ROV´s to as big as 18 tones frames for low frequency sonar systems.

Installations and supervision on site are mostly part of the delivery. Hoist and seachest design, production and installation both for the danish navy and wind-farm vessels has been been performed.

Years of experience in transducer design has resulted in an excellent understanding of mechanical and acoustic behaviors of a sonar system. This is important knowledge when planning an installation and in the development of installation equipment.

For the last few years and ongoing C4R is working with the oil & gas industry in Norway. This works includes mechanical design of frames, trawl-protection, suction and grout systems and christmas trees.
