Bayou Wasco Insulation’s new US line pipe insulation facility is the fi rst in North America to


use Dow’s Neptune two-layer fl ow assurance technology


Bayou Wasco goes for fl ow with Neptune


Bayou Wasco Insulation has commissioned the fi rst fl ow assurance system facility in North America capable of applying Dow Chemical’s Neptune insulation system to oil and gas line pipe at its newly-established facility at New Iberia in Louisiana, US. The company collaborated with Dow Chemical on the


full-scale qualifi cation of the process for Neptune P insulation coating for line pipe and optimisation of the insulation application capability at the new state-of- the-art plant. “We are very pleased with the progress that has been made to successfully and quickly bring this brand new facility on-line,” says Eldridge Indest, vice presi- dent and general manager of The Bayou Companies. The Bayou Wasco Insulation facility, which was

formally inaugurated this month, is located close to the US Gulf Coast oil and gas markets. “We built this plant with our offshore customers in mind, offering them favorable logistics with an accessible location near the Gulf of Mexico. Additionally, we believe they will be very interested in the end-to-end and elevated temperature insulation performance of the pipes coated with Neptune technology that we produce,” says Indest. “Now that we have the ability to produce


coated pipes that will meet our customers’ deep water insulation needs, we are ready to discuss upcoming offshore projects,” he says. Bayou Wasco Insulation is a joint venture


established in 2011 between The Bayou Companies and Wasco Energy. It was estab- lished to provide offshore insulation services to customers in North America, Central America and the Caribbean. The New Iberia facility is confi gured for application of a range of fl ow

assurance coatings, including syntactic polyurethane and multi-layer PP systems as well as the Dow system.


End-to-end solutions The Neptune P advanced fl ow assurance insulation system for line pipe is part of a new proprietary end-to-end fl ow assurance system that also includes Dow’s Neptune F fi eld joint coating and Neptune C coating for subsea architecture. The simple, two-layer system includes an underlay of a high temperature fusion bonded epoxy (FBE) for corrosion protection and an overlay of Dow’s advanced hybrid polyether thermo- set insulation. According to Dow, the hybrid polyether thermoset is


a new insulation technology developed to provide robust fl ow assurance in the increasingly harsh conditions experienced during subsea oil production. Applied over the proprietary FBE layer, the system has passed demanding qualifi cation tests, including small- and production-scale trials employing extreme testing
