Obsolescence Management & Supply of Parts
Effective obsolescence management is essential to safeguarding the long-term reliability, availability, and performance of subsea systems. Given the extended operational life of subsea assets and the rapid pace of technological change, components can become obsolete well before the end of a system’s intended service life. Without a structured approach, this can lead to increased downtime, higher maintenance costs, and elevated operational risk.
Our obsolescence management approach is designed to ensure subsea systems continue to operate safely and efficiently throughout their lifecycle. By proactively identifying and mitigating obsolescence risks, we help operators maintain system integrity, extend asset life, and protect the continuity of underwater operations. This forward-looking strategy minimizes disruption, reduces unplanned interventions, and supports cost-effective asset management in challenging subsea environments.
Strategies for Obsolescence ManagementProactive Identification
We conduct regular assessments of subsea system components to identify items at risk of obsolescence. This includes monitoring supplier lifecycles, manufacturer notifications, and market trends, enabling early intervention and informed decision-making.
Spare Parts Management
Critical spare parts are strategically identified and held in inventory to ensure continued system support. This approach reduces lead times, minimizes downtime, and provides operational resilience when components become unavailable.
Last-Time Buy Planning
Where obsolescence is unavoidable, we support last-time buy strategies by forecasting future demand and securing sufficient quantities of components before discontinuation. This ensures continuity of operations while long-term solutions are developed.
Standardisation
By promoting the use of standardized and widely available components, we simplify maintenance, reduce dependency on single suppliers, and lower the risk of future obsolescence across subsea systems.
Emulation Solutions
For components that are no longer available, we develop or source emulation solutions that replicate the functionality of obsolete hardware or software, allowing existing systems to remain operational without extensive modification.
System Redesign and Upgrades
When appropriate, we redesign or upgrade systems to incorporate modern, supported technologies. This improves reliability, enhances performance, and aligns subsea assets with current and future operational requirements.
Reporting and Visibility
Comprehensive reporting provides clear visibility of obsolescence risks and mitigation actions. Through structured reports and interactive dashboards, stakeholders can track component status, risk levels, and lifecycle forecasts, supporting data-driven planning and long-term asset management.

Leading oilfield services company
Location:
Brazil
Equipment:
Drill pipe riser control system
Depth:
2,500 m
CASE STUDY:
Drill pipe riser (DPR) control systemProject Background
Our client was awarded a five-year contract to provide Petrobras with drill pipe riser (DPR) control systems for deepwater pre-salt fields. These control systems were to operate as an intervention workover control system (IWOCS) for deepwater operations in Brazil. As well as supporting the control of all the subsea operations, including emergency disconnect, well control, tree and downhole smart functions, the system needed to provide control for the tubing hanger running tools and surface test trees.
The client was therefore looking for a high function, highly technical, bespoke system that required significant engineering competence and collaboration to effectively develop, all while ensuring the highest standards in reliability and quality, given the critical safety operations it needed to perform.
The bespoke aspects of the DPR system ruled out an OEM solution and, because a DPR is such a safety critical system, our client needed to engage an established, industry-recognised controls expert. Based on our previous track record with the client, combined with our market leading capabilities in the subsea field, Proserv was awarded the contract to supply nine control systems for the DPR project.
Solution
The DPR systems were run as a rental unit with the client supplying operations and maintenance personnel. As part of the work scope, Proserv was responsible for supporting these project personnel by providing on-site assistance and technical expertise.
The use of a DPR system enables installation and workover on vertical trees in open water without the use of a drilling riser. Annulus services were provided by a 1.5" 10k high collapse resistant core within the umbilical.
Overall project execution, along with engineering and build of the control systems was carried out at Proserv’s subsea controls centre of excellence in Great Yarmouth, with the accompanying hydraulic power units (HPUs) delivered from our manufacturing facility in Malaysia.
Required safety-critical system integration
DPR SCM operated up to 40 subsea functions
Disconnection safeguards for umbilical severance
High-spec HPU, ESD panel and control cabin
Scope
Each of the nine control systems consisted of a surface HPU and control cabin for operation in a Zone 1 hazardous area. The surface control unit within the control cabin interfaced with a drill floor operator screen, emergency shut-down (ESD) panel and the HPU.
The Proserv DPR subsea control module (SCM) operated up to 40 functions on the subsea tree stack up at three separate pressure levels supplied from the umbilical. An automatic disconnect valve and shut-down functionality ensured safe disconnection should the floating drilling unit lose position or the umbilical become severed. Proserv’s specialist dual electronics within the SCM provided redundancy and, with an ROV recoverable SCM, the system was optimised for workover up-time.
Conclusion
Working together with the client, Proserv engineered, manufactured and delivered a bespoke, highly technical controls system for mission-critical deepwater operations.
The Benefits
Safe operations with high reliability and redundancy
Mobile and hazardous area usage
Three selectable pressure levels for flexibility
State-of-the-art electronics and remote connectivity

Magnus Metering System UpgradeProject Background
The Magnus platform is located approximately 160km Northeast of the Shetland Islands and receives production from the Magnus oil field.
This is then exported via the Ninians Pipeline to the Sullom Voe Terminal in the Shetland Islands. The platform also receives dry gas production from the Sullom Voe Terminal, which is commingled with the export gas from the platform and re-exported into the North Leg Gas Pipeline.
This project replaced the existing fiscal metering system which dated back to the late 1990s & also took in allocation and environmental metering previously handled by the site's aging DCS system. The Export Oil Skid was also modified from turbine meters with bi-directional proving to Coriolis meters with Master Meter proving.

Asset extension – metering control systemProject Background
Our client required a new metering control system on board a floating storage unit (FSU). The FSU is undergoing a major overhaul to extend the life of the asset to 2040. They needed a new system that would help to bring the asset up to modern standards and help to reduce maintenance and manual intervention.
Chosen for our reputation
With over 200 metering control systems supplied so far to the industry, Proserv was chosen because of our system’s proven quality and reliability. We had previously completed successful projects for this client and so had a reputation for being flexible and easy to work with.
This flexibility proved crucial, as the project scope eventually expanded to include an additional flow computer. As a result, we had to redesign the metering system’s control panel after the equipment had already been delivered to site. Rather than pulling the equipment back to our measurement center of excellence in Cumbernauld, Scotland, which would have significantly extended the project and added cost, we designed the modifications remotely. The team then reworked the panel and relocated some of the HMI equipment to an area adjacent to the panel on site, all while the vessel was still docked.
Strengthening relationships
We executed part of the system installation and commissioning during the COVID-19 pandemic, without incident. The factory acceptance testing in Norway was far shorter than any of the client and regulator attendees had anticipated, due to its smooth execution and the low number of faults uncovered.
This project further strengthened our relationship with the client and proves again that we can provide an alternative to some of the OEM’s metering control systems.

Subsea Control Modules (SCMs)
SCMs Upgraded:
24 units (12+ recovered)
CASE STUDY:
SCM RecoveryProject Background
In 2023, a Dril-Quip Subsea Control Module (SCM) from the Catcher Field’s CI1 location was recovered following reports of a hydraulic fluid leak. The intervention confirmed that hydraulic fluid was leaking from the gas end valve assembly of one of the three low-pressure (LP) accumulators installed on the SCM.
The faulty SCM was returned to Proserv’s Great Yarmouth facility for detailed inspection and root cause analysis.
Findings
The gas end valve was fabricated from low-grade stainless steel (SS 304), which is not corrosion-resistant in subsea environments
The component was not connected to the SCM’s cathodic protection system, leaving it vulnerable to galvanic corrosion
Corrosion was confirmed as the likely failure mechanism
The associated accumulator bladder was also found to be damaged; however, it remains unclear whether this failure preceded or resulted from the gas end valve issue
Corrective Action Plan
Upon identifying the issue, Harbour Energy initiated a campaign to recover and upgrade all 24 SCMs in the field. The key upgrades include:
Replacing the LP accumulator gas end valve assemblies with corrosion-resistant SS 316 components
Installing earth bonding to ensure future protection via cathodic protection
Refurbishing two SCMs (Unit 10 and 14) at Proserv’s Great Yarmouth facility to serve as operational spares
Scope of Work – Onshore (Proserv Great Yarmouth)
Development of new test procedures and engineering drawings
Load testing and replacement of affected components, including:
Gas end valve assemblies
LP accumulators
Filter assemblies
Removal of all calcifications from anodes to prevent system contamination
Cleaning of all accessible external stainless steel components
Assembly of upgraded SCM housing and completion of all required testing
Scope of Work – Offshore (Proserv Scope)
Removal of SCM side panels and top plates
Initial visual inspection of internals
Secondary wash down with panels removed
Detailed inspection and assessment of LP accumulator gas end valves
Pre-charge checks and top-up of LP / HP accumulators
Removal and replacement of affected gas end valve assemblies
SCM pre-deployment checks following retrofit
Results & Observations
12 out of 14 SCMs (86%) recovered exhibited significant corrosion of the LP accumulator pre-charge components
SCM 18 (BP3) was quarantined after an unsuccessful recovery attempt by vessel contractor, where it fell to the seabed. It was replaced offshore by SCM 10
SCM 22 was recovered and found to have a pre-fitted earth strap. Dril-Quip confirmed that SCMs 22 and 20 had previously been upgraded to the latest revision
SCM 11 was upgraded onshore at Proserv to the latest specification
SCM 19 (CP4) was successfully retrieved and returned onshore for rework. It was replaced offshore by SCM 14
Conclusion
The campaign has effectively identified and mitigated a systemic corrosion risk to subsea infrastructure caused by suboptimal material selection and insufficient cathodic protection. The proactive retrofit program significantly enhances system integrity and operational reliability across the Catcher field.
