Deepwater pipeline coatings can be mixed on site

The new ETNAFLOW portable mixing plant blends glass syntactic polyurethane (GSPU) coating and insulation systems for deepwater pipelines on site in remote locations.

The plant allows for safe and efficient mixing of materials, while an advanced process control helps ensure formulation accuracy and the quality and consistency of the finished product. ETNAFLOW requires fewer human and capital resources to operate, eliminates storage and disposal requirements of conventional GSPU mixing systems and, due to its closed-loop design, helps to minimize potential for chemical exposure or injury to workers from moving machinery, the company says.

Designed for local operations, the portable mixing plant consists of raw materials holding and dosing units, plus a blending operation where the polyurethane and the glass microspheres are mixed. The company ships the unit to the customer's site, provides initial setup, training, remote monitoring, and continuing technical support. Installation and training can be completed in as little as 2 weeks, the company notes.

New underwater tree for marginal field development

The new AZ-10 subsea tree is suited for marginal field developments and fast-tracked projects.

The company says its unit has the ability to reduce the drilling and completion cost for a subsea completion by more than 40%, while reducing the first oil schedule by 15 months.

The AZ-10 is ready to be deployed off the shelf. It features a totally concentric tree and hanger system, and it requires only five tools to install.

The monobore vertical tree weighs less than 50,000 lb, can be handled by all cranes without disassembly, and installed with Gen II or newer semisubmersibles. These features provide for smaller crews and fewer third-party services, the firm points out.

The AZ-10 features a patented universal tubing hanger and running tool system that is factory assembled, easily transported, and ready for quick and easy wellhead and tree interface. The system is flexible and compatible with wellhead equipment from any of the major service providers regardless of profile and any BOP stack.

All of components and assemblies have been designed and validated using API specifications 6A and 17D under the API Q-1/ISO 29001 Quality System Standard requirements.
