Subsea Systems Engineering Subcommittee

DeepStar Core Projects

•            22301   Optimized Chemicals for Subsea Chemicals Storage and Injection Systems (SCSIS) – [Chevron, Total Energies]

SCSIS is a potential enabler for long tiebacks to remote oil and gas fields. Operators, service companies and chemical suppliers' alignment is necessary on the design and operation of those systems. In particular, there is a need to revisit the formulation and qualification of the chemicals themselves, accounting for SCSIS specifics. Such optimized chemicals, typically expected to be more concentrated, will further improve SCSIS economics and ease of deployment.

White Paper Study, New Subsea Chemicals Development – Initial Phase

•            22302   Subsea Chemical Storage and Injection System – [ExxonMobil, Petrobras] NOV –

NOV recently signed a Joint Industry Project (JIP) with Equinor, Shell, ABS, NZTC and The Research Council of Norway. The JIP project will enable the NOV subsea storage system for storage of all relevant types of fluids, and will be the final Product Validation (completed within Q42023). This technology development enables a safe storage solution of larger volumes of fluids to the market, with subsea storage units (SSUs) sizes ranging from 3 m³ to 10,000 m³. The Deepstar project proposed for Deepstar shall present the subsea chemical storage and injection (SCSI) system business case for two different cases.

Product – Advance Technology Readiness Level

•            22303   Brownfield AUV: Subsea Control System Interfaces Supporting Subsea Wireless Devices – [Chevron, Equinor, Total Energies] Sagentia Innovation

This project is a logical next-step after DeepStar 21303 Applying Free Space Optics Subsea. The aim of this project is to identify the technology gaps that will enable the long-term installation of subsea wireless devices in brownfield infrastructure and will benefit device suppliers, subsea system suppliers, and operators. The project aims to make subsea wireless communication devices compatible with as many existing subsea fields as possible.

White Paper Study – Reference future standard in Subsea Wireless

22131 Nanosorbent Technology Platform for the Removal and Recovery of Metals from Produced Water

The project aims at developing a Nanosorbent Technology Platform (Nanoparticle-functionalized sorbents) which can be tailored for the specific removal and recovery of different metals from water. Primary targets of interest include lithium, zinc, and cadmium from offshore oil and gas produced water.

White Paper Study, then Product Development

DeepStar Nippon Subsea Systems Engineering Subcommittee Projects

22133 Application Study and Field Trial of Omni-Directional Optical Wireless Communication System

Omni-Directional Underwater Wireless Communication System is proven technology, and the open water trial of the remote controlling of ROV has also been completed using the industrial blueprint version of the System through Deep Star projects [19133/20133/21133]. This has verified the benefits and the uniqueness of the system which is optical based subsea communication station. To commercialize this technology, further study of engineering requirements for deployment of a field system are required for both brown field and green field cases. Functionality of system to integrate on Subsea Infrastructure and Resident ROV/AUV’s, whose introductions are in progress for deep water autonomous inspection, intervention and for offshore wind farm O&M. The project will focus on field deployment user case, functionality and engineering integration of the system.

Product – Field Test, from pool test and technology capabilities to full scale field trial
