Abstract
The goal of this project is to enhance subsea tieback system safety by maturing the technology readiness level of a new HIPPS system design to an acceptable level for deployment. Because the new system is all-electric, it can be adjusted instantaneously, as compared to hydraulic systems where the adjustment speed slows with distance. The availability of such a system will help improve safety and environmental protection for marginal, highly pressured accumulations of hydrocarbons that must be developed via subsea wells. This project will result in a qualified all-electric HIPPS design suitable for deployment.

The project will build upon non-electric subsea HIPPS experience, methods and standards existing in the industry as well as current developments with subsea electric actuator components and logic controllers. In the course of this work, components with a low technical readiness level will be identified and a technology qualification plan will be developed. Specific components in a representative range of sizes will be built and tested per an established design basis and development work plan. This work will require industry participation with multiple partners. Third-party verification will ensure that development and qualification work meets project requirements.

Granherne, Inc. will lead a project team including key in-house personnel and select industry partners. The inclusion of industry partners is especially important for the actual development and qualification of identified technology gaps.
