The AGSM AIM Group has invested in a specialised geothermal energy project in Verona, Italy, which will see the construction of geothermal wells capable of providing clean thermal energy to those connected to the district heating network.

The project process, which began in December 2023 with the approval by the Board of Directors of AGSM AIM as part of the industrial and economic plan of the ‘Geothermal Project’, will continue over the coming weeks with the establishment of a company to lead the project.

The project will provide geothermal energy to five cogeneration plants in Verona located in Borgo Trento, Forte Procolo, Golosine, City Center and Banks, as well as the Vicenza district heating plants in the future. Utilising geothermal energy is a key part of the objectives and actions envisaged by AGSM AIM’s industrial and strategic plan which places sustainability among the main pillars of growth for the group.

Federico Testa, President of AGSM AIM, said, “Thanks to this important technology our Group confirms that it faces the challenges of the energy sector with a new vocation of values, always directed towards sustainable development and cost containment for citizens and businesses.”

The project aims to bring economic benefits to district heating customers due to the strong reduction of methane gas that will be compensated by geothermal resources. The thermal source is expected to save more than 40% of the gas consumed by the region, thus reducing CO2 emissions by approximately 30,000 tons.

A UK£1mn investment in developing its largest subsea Chopsaw to date has paid off for Decom Engineering (Decom) following impressive results on its first deployment.

The C1-46 Chopsaw played a pivotal role in a subsea infrastructure decommissioning project on behalf of DeepOcean in the northern region of the North Sea.

This ambitious project involved the removal of pipelines, control umbilicals, and various subsea structures from the seabed in water depths of up to 180 metres, each requiring precise and efficient cutting.

The Decom team was tasked with cutting a wide range of pipe sizes, from 1,042 mm OD concrete-coated carbon steel pipes to 220 mm OD super duplex pipes. These subsea pipelines needed to be segmented into 9.5 metre sections for efficient recovery to the vessel deck.

Powered from topside and ROV using a Hydraulic Power Unit (HPU), reeler, hot stabs and control panel, the C1-46 exceeded all expectations, proving its worth in the harshest of subsea environments. The smaller C1-24 chopsaw was utilised for certain tasks and also operated with a mix of topside and ROV controls.

The C1-46 averaged 15 cuts before requiring a blade change, significantly reducing the need for recovery to the surface and impressively completed 79 cuts on its first deployment, showcasing a remarkable 100% success rate.

Substantial time savings of almost 300% were achieved compared to using traditional diamond wire saws which typically have longer cut times, carry a risk of wires breaking, and require multiple trips to the surface vessel for blade replacement. Using customised insertable and replaceable tips voided the need for blade changes, reducing costs and increasing efficiency by minimising vessel time.

In contrast, the C1-46 completed some cuts in as little as 20 minutes, while the C1-24 saw excelled in cutting super duplex and flexible risers - materials that traditional shears can’t handle.

Furthermore, Decom’s innovative approach to reducing seabed dredging time by modifying the saw’s clamps reduced dredge time from 3.5 hours to just 30 minutes.

Established in the United Kingdom in 2011, Decom is an R&D specialist focusing on the design and fabrication of cutting solutions and innovative decommissioning equipment, with a growing reputation for providing complex deep water project solutions.

Decom Engineering Managing Director, Sean Conway, said, “The C1-46 Chopsaw is a remarkable piece of subsea engineering which was designed, developed, and deployed in under six months, specifically for this North Sea decommissioning campaign.

“This project underlined our commitment to engineering innovation and underlined our credentials for pushing the limits of what’s achievable in subsea decommissioning. To efficiently cut through a submerged 1,042mm reinforced concrete coated pipe is not without its challenges, but the C1-46 was more than up to this difficult task.

“It’s been a valuable learning experience and the performance of the C1-46 Chopsaw sets the benchmark for going on to roll out our technologies which offer multiple benefits to contractors and operators engaged in complex subsea decommissioning projects.”

The C1-46 Chopsaw has been designed to cut tubulars and other materials up to 46” diameter and is able to cut a wide range of materials, including inconel alloys, duplex and concrete.

It can be operated in water depths of up to 2,000 metres, has the ability to cut in any orientation, and is capable of multiple cuts per blade (20-100), resulting in large cost savings and increased efficiency. Blade changes are efficient and safe and the chopsaw can be supplied set up in a number of configurations and settings to suit project requirements.

Aker Solutions has secured a significant contract for the dismantling and recycling of a platform topside and jacket in the North Sea.

While expressing its excitement and earning the contract with Saipem, Aker noted that the decommissioning market is a growing market and one that is rapidly growing its backlog of orders.

“This award adds to an order backlog that already stretches to 2030, and provides further predictability so that we can continue to develop our facility and execution model, with a strong focus on safe operations and capability to deliver a high degree of recycling,” remarked SVP Decom Thomas Nygård.

Indeed, according to the company, it is knowing how to conduct such operations which won this contract. As per the order, Aker will support the receiving, dismantling, sorting and recycling 19,000 tonnes of topside and a steel jacket weighing 10,000 tonnes. These structures will be delivered mainly as modules by Saipem’s semi-submersible heavy-lift vessel, Saipem 7000 between 2025 and 2027.

Of this, 98% is expected to be recycled, representing a key component of the circular economy.

Serica Energy has provided an organisation and operations update, charting the successful operations it has carried out in the North Sea since September.

The latter half of 2023 has seen Serica successfully carry out the summer shutdowns at both the Bruce and Triton fields. In the former, the shutdown workscope was completed later than planned due to the decision to carry out permanent rather than temporary repairs on the flare tower.

Strong levels of production have been established from both the Bruce and Rhum fields with Serica’s average production entitlement being over 24,000 boe per day during the last four weeks.

Commencing in September, Serica has been conducting its second Light Well Intervention Vessel (LWIV) campaign on the Bruce field. This has involved successfully re-entering three wells to identify areas of scale build-up, perform water shut offs and perforate target intervals. With work on one well still to finish, there has been an uplift in overall production from the re-entered wells of about 2,500 boe per day so far.

Serica has now intervened on five of the subsea wells that form the Western Area Development (WAD) part of the Bruce complex. Since taking over operatorship, Serica has also re-entered fourteen Bruce platform wells. The results have demonstrated the benefits of low cost well interventions and a third LWIV campaign is planned during 2024 which will involve work on both Bruce and Keith wells. The inventory of platform wells on the Bruce field is also being high graded for potential future interventions.

The company is also currently carrying out vessel-based final abandonments of four exploration and appraisal wells on the Keith field and the North Eigg exploration well. This campaign is consistent with the NSTA’s initiative to reduce the number of suspended inactive wells in the UK North Sea. The abandonments are scheduled to be completed in late December 2023.

At Triton, the summer shutdown was completed in September 2023 with the activities carried out including essential fabric maintenance and inspections, a further phase of the control systems upgrade and preparation for the reinstatement of water injection on the Bittern field, which is planned to restart in early 2024. Good production rates are being achieved from all of Serica’s fields in the Triton Area.

During the middle of this year, a rig-based well intervention campaign was carried out on the Guillemot West and North West fields. These were the first such interventions on the fields in over ten years and have resulted in incremental gross daily production of about 1,500 barrels of oil from one well and 12 million cubic feet of gas from another, both of which had been shut-in for lengthy periods.

Mitch Flegg, Chief Executive of Serica, explained, “I am pleased to report the successful conclusion of the planned summer shutdowns on Serica’s Bruce and Triton hubs and the re-establishment of strong levels of production at both. During the last month Serica has been consistently achieving production rates in excess of 50,000 boe per day. Overall production guidance for the year is unchanged reflecting delayed production restarts and slower than expected production ramp-ups after the summer shutdowns.

“I am also pleased to report successful well campaigns on the Bruce and Guillemot fields during 2023. These are further proof of the benefits to be had from low cost, short cycle investments in our existing asset portfolio. The full impact on production of the well work carried out this year is expected to be felt in 2024, aided by the work on the Bruce facilities deferring the need for another major shutdown until 2025.

“The LWIV vessel used on Bruce is already booked for a third campaign in 2024, which will target wells on both the Bruce and Keith fields. We are also looking forward to the start of a four well drilling campaign in the Triton area, with the first well on the Bittern field scheduled to begin around the middle of the first quarter. 2024 is anticipated to be a very busy and impactful year of investments in Serica's North Sea portfolio.”

Harbour Energy, the operator of the Viking CCS CO2 transportation and storage network, has announced that the Planning Inspectorate has accepted for examination its application to build the Viking CCS onshore CO2 transportation pipeline in the UK.

The 55 km pipeline will transport captured CO2 from the Immingham industrial area to the former Theddlethorpe Gas Terminal site. From there, it will be sent to the depleted Viking gas fields, located 2.7 km under the seabed for permanent storage.

The pipeline is considered a key component to decarbonise and rejuvenate the industries of the Humber, potentially unlocking UK£7bn of investment across the full CO2 capture, transport and storage value chain over the next decade. The acceptance by the Planning Inspectorate is the next stage in the process to acquiring a Development Consent Order (DCO) for the pipeline and follows a comprehensive programme of consultation and engagement with local communities and stakeholders.

“This is another critical step forward towards delivering our Viking CCS project, which will create thousands of jobs in the Humber region and is targeting 10 million tonnes per annum of CO2 emissions reduction by 2030, vital for the UK to deliver its climate ambitions,” remarked Viking CCS Project Director Graeme Davies.
