Materials used for subsea buoyancy fall into three main groups which can be defined in general terms as:
* Polyurethane Foam.
* Co-polymer Foam.
* Syntactic Foam.
Each of these materials is immensely versatile and the most appropriate specification is achieved by careful analysis of product operating conditions, which include:
* Operating Depth and Duty Cycle.
* Maximum Depth.
* Buoyancy Required.
* Geometry of Element
* Method of Attachment.
* Method of Installation.
No two applications are the same and with the correct data available, material specifications can be formulated precisely to achieve optimum product performance.
