SUBSEA & OFFSHORE

Core material for subsea and offshore

Diab has more than fifty years of experience from buoyancy foam for defense and oil & gas operations, but composite materials are expanding into many other subsea and offshore applications, where high-quality buoyancy, strength and long lifetime are key.

Our closed cells foams are appreciated for their high buoyancy per weight, low density and high uplift. They are commonly used as floatation units in remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs), as well as submarines, diving bells and offshore renewable energy solutions, such as wave and tidal power generation.

Also, shallow water buoyancy, such as floatation units or moorings benefit from our low-density foam. The light weight does not compromise the toughness of the product. PVC foam cores are chemical resistant, can handle high impact and offer long term creep resistance, improved thermal/acoustic insulation and excellent transmittance. In addition, they are easy to machine, making shaping easier and more efficient.
