The progression of Subsea Chemical Storage & Injection (SCS&I) technology signifies a pivotal shift in the operational framework of hydrocarbon extraction, transitioning significant components of the production system to the subsea environment. This transition is driven by the imperative to exploit distant reserves economically, facilitate extended subsea architectures including long-distance tie-backs and direct seabed-to-shore configurations, and integrate with existing top-side infrastructure that has reached its capacity limits. Additionally, SCS&I is key in the push towards "All-Electric" subsea designs, where the umbilical's role is minimized to power supply and data transmission.

Requirements for Pumps

Efforts to enhance and broaden the application of SCS&I technology are a focal point of collaboration within the sector, with industry innovators at the forefront.

The SCS&I initiative is anchored in three primary objectives:

1. Minimizing the financial footprint of projects by scaling back on umbilical costs and reducing the operational impact on surface-level facilities, including considerations for weight, spatial allocation, and necessary modifications.

2. Eliminating constraints imposed by the original design or damage to infrastructure, both at the surface and subsea levels.

3. Enabling the deployment of specific chemical agents directly at the subsea level, which due to their physical properties or safety considerations, are not suited for transport through conventional means.

The spectrum of potential for SCS&I application is broad, influenced by diverse factors such as the architectural layout of fields, the distance from these fields to processing facilities, the state of existing infrastructure, and the natural depletion trajectory of the reserves. Nonetheless, it is recognized that SCS&I may not be universally applicable across all scenarios. It is crucial for stakeholders, including end users and integration specialists, to discern situations where SCS&I can effectively contribute to reducing operational costs, augmenting production capabilities, or enhancing flow assurance. This necessitates a nuanced analysis, delineating scenarios where SCS&I technology yields the most value, particularly in extending the operational reach of new fields and unlocking latent potential in mature developments.

High pressure subsea pumps are at the core of a Subsea Chemical Storage & Injection (SCS&I) and require very careful design as they are installed on the seabed.


Design Concept

The unique Peroni Pompe Nettuno 3120 triplex plunger pump, in service since 2004, started with a bold concept: engineering an open power frame. The open frame exposes the internal mechanical components to the hydraulic atmosphere of ocean depths and eliminates the pressure differential from the equation at depths.
The key advantage of the Nettuno pump is the crank case (mechanical power frame) of the pump is cooled and lubricated by sea water. No oil or grease is required. The depth of operation is not a factor for this subsea pumping technology.
The pumping unit is supplied completely assembled including a standard subsea electric motor drive.

Thanks to its 20 years references, the Nettuno 3120 triplex plunger pump is TRL7. The Nettuno 3120 plunger pump is suitable for:

- high flow intermittent batch chemical injection
- low flow (typically continuous) chemical injection
- flowline intervention or testing (ROV)
- fluids: (sea)water, MEG, methanol, LDHI, Biocide, Corrosion inhibitor, Scale inhibitor…

Operating range of Nettuno:

- Up to 1400 bar (20.000 psi) differential pressure
- Up to 100 lpm (26 gpm)
- Up to 53 lpm (14 gpm) at 700 bar (10.000 psi) differential pressure
- A larger quintuplex (5 plunger) model is available upon request

The Peroni Nettuno 3120 is developed on the proven 100J3-UW pump by Jetech (a member company of Peroni Pompe Group), in service since 2004 for subsea intervention work.
