Dow subsea insulation system named one of 2013's most influential innovations

HOUSTON -- Dow Oil, Gas & Mining, a business unit of The Dow Chemical Company, has been awarded a 2014 R&D 100 Award from R&D Magazine for the DOW NEPTUNE advanced subsea flow assurance insulation system. The NEPTUNE system is based on a new, proprietary insulation material that offers uniform, high performance from the well-head to the delivery point, along with the widest installation and operating temperature range of any wet insulation system on the market.

The R&D 100 Awards identify and celebrate the top technology products of the year. Past winners have included sophisticated testing equipment, innovative new materials, chemistry breakthroughs, biomedical products, consumer items, and high-energy physics.

"With the demand for oil and gas continuing to rise and reserves becoming increasingly difficult to reach, the NEPTUNE insulation system allows producers to access valuable resources from more extreme environments in a safe and reliable way," comments Alex Lane, global business segment manager - Transmission, Dow Oil & Gas. "We are proud to be recognized for this breakthrough technology, developed in cooperation with leading industry coaters, which helps shorten qualification time and minimize project risk."

The NEPTUNE system is a simple, all-in-one insulation system designed for casting around deep subsea flowlines and ancillary equipment. While competitive line pipe coating systems can require as many as seven layers, NEPTUNE insulation has only two: a robust and homogenous layer of novel insulation over a proprietary fusion-bonded epoxy. This simplified system eliminates the need for glass microspheres, multiple materials and adhesive tie layers, which reduces the potential risks associated with bonding dissimilar, potentially incompatible materials and contributes to a thinner coating profile.

NEPTUNE insulation is engineered to withstand the increasingly harsh conditions associated with subsea oil production, including broader temperature ranges and higher pressures. The insulation’s tested physical properties include flexibility down to -40°C (-40°F), thermal stability at service temperatures up to 160°C (320°F), and a consistently low K-factor.
