The development of Subsea Chemical Storage & Injection (SCS&I) technology is a continuation of the trend to move more of the hydrocarbon production systems subsea. This is driven by a need to make exploitation of remote resources profitable; unlock single-line long tie-backs and subsea to shore architectures, and to enable tie-ins with otherwise constrained topside infrastructure. The SCS&I System is also a significant contributor to the development of "All-Electric" subsea architecture where the umbilical is reduced to a power and communication cable only. TechnipFMC https://www.technipfmc.com/ and Total https://www.total.com/en are collaborating to develop and qualify the SCS&I technology components and system. In order to make the SCS&I technology competitive and field developments profitable, the reliability of the equipment is paramount. The HAMPRO 70V injection pump is one key component in the system for which high reliability must be ensured. The objective of the qualification program is to confirm the adequate performance of the HAMPRO 70V pump in the following areas: The reliability of the chemically exposed parts and the impact of chemical fluid cleanliness The reliability of the pump and motor rotating parts and the impact of lubricant performance The reliability of the electrical components The impact of transient behaviour on the pressure compensation system, rotating parts and electrical components Due to the similarity of design, smaller versions of the HAMPRO pump will also be qualified by the activities in the program.

The development of Subsea Chemical Storage & Injection (SCS&I) technology is a continuation of the trend to move more of the hydrocarbon production system subsea. This is driven by a need to make exploitation of remote resources profitable; unlock single-line long tie-backs and subsea to shore architectures, and to enable tie-ins with otherwise constrained topside infrastructure. The SCS&I system is also a significant contributor to the development of "All-Electric" subsea architecture where the umbilical is reduced to a power and communication cable only. TechnipFMC and Total are collaboratively working together to develop the SCS&I system and advance the technology. The objectives of SCS&I can generally be divided into three categories: Reduced overall project cost by reducing umbilical cost and minimizing topside requirements (weight, space, modifications)De-bottlenecking of installed and/or damaged topside or subsea infrastructureEnabling injection of chemicals which cannot be transported to injection points via traditional means, for example high viscosity chemicals and/or chemicals with significant risk to personnel during topside handling Within the wide variations of field architecture, step out distance, age of infrastructure and field depletion characteristics, the opportunities for successful application of SCS&I are huge. However, not every case is a good SCS&I case. End users and system integrators need to be able to identify where the SCS&I technology can make a difference in terms of reduced cost, increased production and/or improved flow assurance. The paper addresses this by illustrating break-even point in terms of step out distance for Green Fields and identifying typical cases where SCS&I can unlock value in Brown Fields.

Due to a strong economic and demographic growth around the world, global energy needs are going to increase by about 35% from now until 2030 and energy must be saved. In addition to this, GHG emissions must be reduced in order to limit the consequences of global warming. In this context, TOTAL is working on minimizing flaring and on improving the energy efficiency of its existing and future facilities. The in-house tool presented in this paper, EAT (Energy Architecture Tool), is primarily designed for future E&P facilities: it aids in the selection of an energy-efficient and low GHG-intensive architecture, during conceptual and pre-project studies. The tool allows doing the case-by-case approach instead of a "dogma" saying that a specific architecture is equally efficient in every case. It has been validated on four new projects. Contrarily to studies based on design cases, i.e. extreme cases, this tool simulates the behavior of the energy generation unit (mostly gas turbines) and the energy users (compressors, pumps, furnaces), for the various flows, pressure and heat requirements over the field life. These requirements are less constraining than the design case, but they last much longer, and thus they are to be considered for the energy efficiency purpose. EAT is a two-steps tool. The first step is to set a reference of energy consumption / GHG emissions. The reference is not a target but it is an ideally optimized case taking into account the process constraints (e.g. the amount of gas to be compressed, its molecular weight, the required suction/discharge pressures per year, site conditions…). The second step is the screening of several architectures to get as close as possible to this reference over the field life. The various alternatives simulated are: number of compression / pumping trains installed, load shedding strategy, use of constant or variable speed drive, all-electric configuration (turbogenerators and electrical drivers only) versus distributed power generation (e.g. turbocompressors), turbine model or other drives, electricity import or export etc. Once the optimal architectures are identified, the Process, Operations, Technological and Architecture teams check the operability, availability, technical feasibility and economic profitability aspects. The tool can also be used for existing fields, for building GHG mitigation plans, for setting challenging yet achievable objectives to Operations teams and for developing more accurate forecasts.
