Coatings for deep-water pipelines can be mixed on-site by new mobile technology

Dow Hyperlast has engineered a technology to blend glass syntactic polyurethane (GSPU) coating and insulation systems for deep-water pipelines on site in remote locations. ETNAFLOW™ Portable Mixing Plant from Dow Hyperlast, a division within Dow Polyurethane Systems, allows for safe and efficient mixing of materials, while an advanced process control ensures formulation accuracy and the quality and consistency of the finished product. According to the company, the benefits of ETNAFLOW™ include need for fewer human and capital resources, elimination of enormous storage and disposal requirements of conventional GSPU mixing systems due to its closed-loop design, minimizes the potential for chemical exposure or injury to workers from moving machinery. Designed for local operations, ETNAFLOW™ Portable Mixing Plant consists of raw materials holding and dosing units, plus a blending operation where the polyurethane and the glass micro spheres are mixed. Dow Hyperlast ships the unit to the customer's site, provides initial set up, training, remote monitoring, and ongoing technical support. Installation and training can be completed in as little as two weeks. The new mixing system was developed as a direct result of a requirement to supply Wasco Coatings in Malaysia, with Flow Assurance Insulation coating materials for the Gumusut-Kakap project. The requirements of this South China Sea project demanded performance parameters at ocean depths of up to 1,200 meters in very remote areas.
