Structural performance management provider, Akselos, has launched its cutting-edge SPM for FPSO 4.0 software

The software enhances asset performance, ensures uninterrupted operations and extends asset life of FPSOs.

SPM for FPSOs can reduce operational expenditure (OPEX) by up to 35% through optimised inspections and maintenance planning, minimising planned and unplanned downtime while significantly boosting resolution span for structural issues. Furthermore, by extending safe operating windows the tool helps operators avoid millions in lost production by potentially avoiding unnecessary dry dock.

The software also allows FPSO operators to extend the operational life of assets by removing unwanted and overly conservative fatigue estimates, powered by Akselos’ RB-FEA technology. It helps operators unlock spare structural capacity in compliance with class and standards. It provides millimetre-level precision in monitoring structural integrity of the entire FPSO in one holistic detailed model, enabling FPSOs to operate safely for longer periods.

Allowing data integration

Akselos delivers a near real-time, structural twin of the entire FPSO, allowing operators to continuously monitor asset health, identify stress hotspots, and run 'what if' scenarios to mitigate risks. By integrating operational data like inspection data, metocean data and tank fills and unloading etc, the software provides continuous and on-demand fatigue assessments, reducing the risk of unplanned downtime. The solution is also compliant with class society standards and helps operators maintain regulatory compliance with near real-time insights, ensuring safer operations in extreme offshore conditions.

The solution integrates seamlessly with existing systems such as inspection data management systems (IDMS) and risk-based inspection (RBI) workflows, ensuring operators can easily incorporate it into their current operational infrastructure without disrupting established processes. This smooth integration accelerates the adoption process and improves overall operational efficiency.

“In the true spirit of Industry 4.0, we’re revolutionising FPSO operations like never before. SPM for FPSO 4.0 is a game-changer - empowering operators to unlock unprecedented levels of efficiency, optimise operational costs, minimise downtime and extend the life of their assets. This isn’t just about keeping up with industry standards - it’s about breaking barriers and setting new benchmarks for what is possible,” said Claus Reimers, chief product and technology officer at Akselos. 

From Mauritania and Senegal to Angola, Africa has seen the deployment of FPSOs in the recent months for several significant projects.

Offshore engineering solutions provider Aquaterra Energy has launched well re-entry and re-abandonment services along with its new patent-pending recoverable abandonment frame (RAF)

The combined solution will address challenges in locating, re-entering and re-abandoning legacy wells that penetrate, or pass through, offshore oil and gas reservoirs or saline aquifers that have been earmarked to be repurposed for carbon dioxide (CO2) or hydrogen storage.

The significant economic and technical challenges of re-abandoning problematic legacy wells that pose a leak risk beneath the seabed could derail many carbon capture and storage (CCS) and hydrogen storage projects, that intend to use previously penetrated oil and gas or saline aquifer formations. Technical challenges such as traditional relief well drilling could be infeasible in shallow intersects or where azimuth and depth are unknown.

Excavation methods require enormous amounts of material to be removed and may also fail to isolate re-abandonment loading from the compromised legacy well, meaning both methods may fall short in addressing technical, environmental, safety, and regulatory issues effectively.

Aquaterra Energy’s solution overcomes these challenges by employing advanced seabed and subsurface surveying technologies, well imaging, marking, and tagging to precisely locate wells. This allows the RAF to adjust to an exact well position and install conduits below the seabed to re-engage the legacy well and then back to the surface to allow for successful re-abandonment via a vertical well re-entry tieback method. Crucially the RAF also protects the legacy well components from environmental, lateral and axial loading generated by wave action on the tieback conduits and the re-abandonment operation itself.

RAF to address energy transition

George Morrison, CEO at Aquaterra Energy, said, “The introduction of the RAF and our re-entry services illustrate our strategy of pivoting decades of offshore expertise to address the wider challenges of the energy transition. Our team is committed to innovating and taking on the tough issues, ensuring that carbon and hydrogen storage can be effectively delivered as part of our broader commitment to driving the energy transition forward.”

The technology is intended for repeated use across multiple wells or locations with flexibility built in for differing seabed conditions. Its modular design allows for shipping worldwide or road transport for quayside assembly. This could enable the effective abandonment or re-abandonment of wells that may not have been previously possible, while also significantly lowering costs, saving operators £18-20 million per abandoned well - an estimated 80% reduction in comparison to other methods currently deployed. The approach could also lead to major reductions in project timelines, estimated to be up to 50% quicker per well.

"The RAF and our associated suite of services for legacy well re-entry represents a significant leap forward in abandonment technology," said Ben Cannell, Innovation Director at Aquaterra Energy. "Well re-abandonment for CCS is a new challenge, and our solution has been developed to meet it head-on. By reducing project risk, costs and operational time, we're not only making well abandonment more efficient, but also enabling the viability of carbon or hydrogen storage, as these projects would generally be far more costly or even impossible to deliver." 

Aquaterra's presence in Africa goes way back, when the company delivered an installation project for Chevron offshore Angola, or worked on a platform development in Niger Delta.

Michael Smith Engineers has introduced the TPM magnetic-coupled peripheral pump, engineered by Dickow Pumpen

The latest addition to Michael Smith's extensive range of high-performance pumps, this innovation is designed for application across industries, including oil & gas, chemical, petrochemical, aviation, and renewable energy. 

Also known as turbine pump, the TPM peripheral pump works like any centrifugal and side-channel pumps. It is ideally suited for applications with limited suction head as it comes with a low net positive suction head (NPSH).

The TPM range can deliver flow rates of up to 17 cu/m per hour and a maximum differential head of 400 m. With a design pressure of 40 bar and maximum operating temperature of 300°C, the TPM range is built to ensure reliable performance even under the most challenging conditions.

One of the standout features of the TPM peripheral pump is its ability to handle liquids with entrained gas, enabling continuous operation even during gas release or temporary air ingress. Additionally, its hermetically sealed design makes it an excellent choice for handling toxic, explosive, or environmentally hazardous fluids, ensuring safety and compliance with stringent environmental standards. 

Today's advanced pump solutions are designed with energy conservation and sustainability in mind, as highlighted by Yasser Nagi, managing director of Wilo Middle East, speaking at the recent World Future Energy Summit.
