Dow Chemical developed its Neptune P insulation for line pipes and Neptune F insulation for field joints for offshore flow assurance applications. The insulation was tested in conditions from -40°C through 160°C. The insulation has two layers: a homogenous layer of insulation over a proprietary fusion-bonded epoxy. This system eliminates the need for multiple materials and adhesive tie layers, which reduces the potential risks associated with bonding dissimilar and potentially incompatible materials and contributes to a thinner coating profile. With components for coating line pipe, field joints, and subsea architecture, the system protects assets from subsea wellheads to delivery point.
