Hyperlast Limited launched a new material at Offshore Europe. The company believes that building on the success of its Hyperlast Syntactic 512 for insulation and protection of pipelines, this new development, DW-512, will take polyurethanes beyond existing limits for deep-water applications.
For a material to withstand the elements and protect sub-sea pipelines, it requires versatility to meet differing requirements and field conditions and must perform reliably over many years in harsh environments.
As current oil fields dry up, operators are now looking to develop new projects and are exploring fresh fields in deep water. In response to this demand, Hyperlast reports that it has extended its product range for use in deeper water-fields.
The DW-512 is a new modified version of "Hyperlast" Syntactic 512. This claims to prevent hydrate formation in gases and waxing in crude oil in sub sea flow lines, manifolds, and risers.
According to Hyperlast its polyurethane range has found widespread approval from the international offshore industry, and is used extensively by many of the industry's leading names including BP Amoco, Conoco, Exxon, Mobil, Shell, Statoil, Total and Texaco among others.
"Hyperlast" Syntactic is described by the company as a stand alone, single layer coating that combines physical protection with thermal insulation. Its closed cellular composition, based on the use of evenly distributed micro spheres, provides long-lasting protection and reliable performance in inhospitable environments.
Hyperlast also informs us that the new material uses glass micro spheres in its composition to be non-compressible at depths of 500m to in excess of 2,000m and its insulation properties do not succumb to fluctuation. It also reports that there is no restriction on the thickness of material used. DW-512 can also be applied using the same method as the current "Hyperlast" 512 material, either by moulding or rotational casting.
