Island Offshore, which owns an extensive fleet of offshore service vessels with a range of capacities, has indicated that their 2023 light well intervention work programme is filling up with several clients planning to increase the use of their service.
The company provided this information in a social media post where it suggested that utilisation is looking to improve further from 2022 levels. It added that the Island Wellserver vessel will be fully utilised in 2023 working on the Norwegian Continental Shelf and will, in December, be dry-docked at Ulstein Yard for class renewal.
The Island Constructor is currently trading outside the North Sea but will return to the region in February to undertake multi-client LWI work throughout 2023.
Continuing, the company explained that its riserless well intervention units are part of a cost-effective and flexible service alternative to rig-based interventions with a value proposition that has shown to be appealing to customers. The subsea well services include diagnostics, stimulation, monitoring, zonal isolation, and mechanical repairs.
Since 2005, Island Offshore has partnered with TechnipFMC and other alliance partners as first moves to complete more than 400 well interventions. The post concluded, “We are proud to be a small but significant player in the market.”
Celebrations rang through the night last week as the third annual OWI Awards 2022 brought industry giants together to highlight the very best in offshore well intervention.
This year the ceremony was hosted in Aberdeen on 25 November, 2022, and showcased a host of innovative technologies and solutions over the span of eight categories. The judging panel was made up of top operators from around the world ready to find the best of the best in well intervention.
Vaarst kicked off the night by taking home the Digital Transformation Leader trophy for its excellent work on the SubSLAM X2, a trailblazing digital solution which collects real-time intelligent data in order to deliver underwater live 3D point clouds with sub-millimetre precision.
Next up was Expro which was the big winner of the night, claiming victory in two award categories; Champion Integrated Well Service Company and Most Innovative Solution. The company’s integrated subsea intervention package and Octopoda system were recognised by the judging panel for their ingenuity and impact on the outer industry, thus earning the double win.
The award for the Best Example of Collaboration went to AKOFS Offshore in this hotly contested category, for its exemplary work with Equinor, offering the AKOFS Seafarer for integrated services utilising the company’s OneTeam model. The services are provided through four entities – AKOFS Offshore, IKM Subsea, Archer and Welltec – highlighting the integral prosperities of collaborative work within the industry.
Tendeka took to the top spot for the Best Project Outcome award, shining a light on the company’s remedial solution, Filtrex Conformable Sand Screen, which showed huge success restoring sand-free production across a three-well campaign in Indonesia. The remarkable performance earned Tendeka high recognition from the judging panel.
As sustainability is an incredibly hot topic within the industry at the minute, the award for Environmental Sustainability Innovation presented a very strong roster, but ultimately there could only be one winner, and Exceed pipped everyone else to the post. The company is on a mission to be the global leader of intergraded well management for energy transition, and was subsequently rewarded for its work on carbon neutral well operation.
SLB was awarded for its Plug and Abandonment Excellence thanks to its industry-first wireline service, Epilogue Isolation, wherein operators are no longer required to remove the inner pipe to evaluate well integrity, revolutionising conventional operations. The service reduces P&A rig days, minimising costs and reduces carbon footprint, all of which make the company a worthwhile winner in the eyes of the judges.
To end the ceremony, the final award was that of Significant Contribution to the Industry; an award which showcases the impressive portfolios accumulated by the finalists over the span of their respective company life cycles. The winner of the prestigious award was Weatherford for its rig-less framework approach to decommissioning pre-abandoned phase 3 wells.
Overall, the ceremony was a cause for celebration for not only the winners, but for all the finalists for all the hard work and dedication each operator has put into making the well intervention industry be the best it can be.

Offshore Energies UK (OEUK), the leading representative body for the UK’s offshore energy industry, has published its latest Decommissioning Insight report.
More than 2,000 North Sea wells involved in oil and gas extraction are to be decommissioned at a cost of around UK£20bn over the next decade, says a new industry forecast.
The wells have played a crucial role in providing the UK with the energy to keep homes warm, run businesses and power vehicles.
Decommissioning is the process of withdrawing offshore energy infrastructure from use once it’s no longer needed or at the end of its lifecycle.
The report finds UK decommissioning is expanding fast and predicts a surge in activity over the next three to four years. It says the sector will continue growing as other emerging offshore energy technologies, like offshore wind farms, also require the service.
It is estimated around 2,100 North Sea wells will be decommissioned over the next decade – around 200 per year – at an average cost of £7.8mn per well.
In 2021 a 10th of UKCS oil and gas expenditure went into decommissioning. This proportion has risen to 14% in 2022 and is set to rise to 19% by 2031. Over the next 10 years, expenditure on decommissioning is predicted to total £19.7bn, with well decommissioning comprising nearly half of this spend.
Over 75% of total decommissioning spend will be within the central North Sea, (stretching from Yorkshire to the northern tip of Scotland), and the northern North Sea, (covering an area north of Scotland and east of Shetland and Orkney). The surge in work could particularly benefit industrial communities on adjacent coastlines, especially around Teesside, Humber, Aberdeen and Inverness. Decommissioning in the Irish Sea will generate more economic benefits in places like Merseyside.
However, the growth in other renewable energies, such as offshore wind, could cause bottlenecks in demand for decommissioning services, the report says.
It means the offshore wind, carbon capture and storage, and oil and gas sectors will need to work together and be transparent about planned projects to make sure the opportunity is properly managed.
OEUK Decommissioning Manager, Ricky Thomson, said, “The UK’s decommissioning sector is snowballing and will continue growing for years to come.
“But this poses a challenge as well as an opportunity. The growth of renewables and demand for decommissioning services and expertise will create increasing pressure for resources.
“This is a great problem to have and it’s vital this opportunity is properly managed across the sector so that UK firms can capture the lion’s share of this £20bn opportunity.
“With the right support from government and action from the industry, the UK could make major gains from decommissioning, as well as retain thousands of jobs for this growing sector.”
ASCO, a provider of fully-integrated logistics and materials management services in the oil and gas, decommissioning and new energy sectors, has secured four new contracts for NORM decontamination and disposal services with major operators, worth more than UK£10mn.
NORM Solutions, part of ASCO's environmental service division, has won the multi-year contracts with leading operators to provide safe management and decontamination of naturally occurring radioactive material (NORM) on North Sea installations as they are decommissioned.
NORM Solutions will handle the receipt and decontamination of all types of offshore materials and equipment, safely cleaning the items to be returned offshore or recycled. They will also handle NORM-contaminated sludges and liquids, repackaging these for safe onward transport and disposal.
The contracts will be further supported by deploying ASCO's radiation protection supervisors, who manage the offshore processes required to identify and safely store and offload any contaminated material.
Chris Lloyd, Head of Environmental and Decommissioning at ASCO, said, "Since ASCO acquired full ownership of NORM Solutions in 2019, the business has gone from strength to strength. The quality of our facilities and the professionalism of our team at NORM Solutions has played a major part in these contract successes and we greatly appreciate our customers faith in the services we deliver.”
Lloyd continued that with the UK acting as a leader in the decommissioning market worldwide, he anticipates continued growth at NORM Solutions to service increasing demand.
Blue Ocean Seismic Services, the marine seismic survey disruptor, has completed a series of passive and active seismic trials proving the quality of seismic data collection, putting the company on track to commence pre-commercial trials during the second half of 2023.
Backed by industry leaders bp Ventures, Woodside Energy and Blue Ocean Monitoring, the UK/Australian tech company is developing the world’s first fleet of autonomous low-impact subsea nodes for capturing high-quality seismic data from the ocean floor for multiple applications such as offshore wind, oil and gas, and CCS. These underwater vehicles will transform the offshore seismic sector to become more affordable, faster, safer, environmentally friendly and significantly less carbon intensive.
Since its last update, the company has undertaken substantial further testing in Plymouth, the North Sea and Australia towards confirming the effectiveness of command and control systems, underwater flight performance, seismic coupling and active seismic data acquisition.
Focusing on the recent North Sea active seismic trial, the company achieved its technology and data collection objectives, including:
*Acquiring additional cycles of active seismic data with its alpha vehicles (AP-OBSrV) alongside conventional ocean-bottom nodes (OBNs)
*Testing engineering solutions for optimisations identified in the previous (August 2021) trials
*Confirming the ability of the AP-OBSrV to maintain a close seismic coupling with the seabed, especially where cross currents exist.
These objectives were all achieved in the active seismic survey, in particular confirming that the geophysical performance is on track. With this confirmation, the company will continue its rapid progression towards the commencement of commercial operations in 2024, starting with the assembly of up to 250 OBSrV version 1 nodes (based on the AP-OBSrV design) in batches, with pre-commercial trials in H2 2023.
Before commencing pre-commercial trials in H2 2023, the company is progressing discussions with industry partners regarding their strong interest in our services and pre-qualifying for future tender opportunities. In addition, following substantial interest from potential customers, the company also plans to open a new office in Houston, Texas, in Q1 2023, in line with its strategy to establish a presence in key markets.
Blue Ocean Seismic Services is delighted to announce the appointment of Fabio Mancini, PhD, as Chief Geophysicist. Fabio joins Blue Ocean Seismic Services from Woodside Energy where he was Chief Geophysicist from 2018. He has extensive industry experience; he spent five years at TotalEnergies in R&D and operations, working on projects covering both seismic processing and acquisition. He subsequently moved to Hess, where he worked in the Exploration and Production Technology team and was in charge of Hess’s seismic activities for the Eastern Hemisphere. He then moved to Australia to join Woodside where he covered several roles over 10 years.
Simon Illingworth, Managing Director and CEO, Blue Ocean Seismic Services, said, “The successful results of the various pre-commercialisation trials over recent months are the culmination of a huge amount of work by the Blue Ocean Seismic Services team and represent a massive leap forward on our path to full commercialisation. We are now in an excellent position to continue with the operational scale up of the business, engaging with government regulators in our key initial markets and begin commercial operations in 2024. Substantial investment is also being made in securing components for our initial inventory of pre-commercial vehicles.
“As a leading figure in the subsea exploration sector, it is a huge endorsement to have someone of Fabio’s calibre join the business, he will bring considerable expertise and experience to the team as we move to the next phase of our development.”
Mancini said, “I am very excited to be joining the team at Blue Ocean Seismic Services. As one of the co-inventors I look forward to realising the vision of transforming seismic acquisition in the years ahead.”
Global well integrity and production optimisation firm, Coretrax, has created a casing integrity solution for a major North Sea operator which is said to eliminate the need for a casing string to be replaced.
The project saw a team of three engineers identify and mobilise the trouble zone, and install a short patch on a casing section of the well affected by corrosion.
To pinpoint the trouble zone, the engineers deployed its CX-RTP (retrievable test packer), a heavy-duty service packer used to set and pressure test a range of depths to identify the area in need of patching.
Following the identification of the trouble zone, the company deployed its ReLine HYD expandable casing patch to isolate the area and regain well integrity without the costs associated with replacing the casting.
Western Hemisphere President at Coretrax, Keith Bradford, said, “Our team of engineers worked collaboratively to identify how we could combine technologies from across our portfolio to effectively meet our client’s objectives. We mobilise products from CORE, our expandable tubular product line, and packers from our AEON line which we use for plug and abandonment solutions.
“The outcome was a great success and allowed our client to not only continue operations with minimal disruption or downtime, but also potentially saved costs on replacing the entire casing string.”
The project was completed in five days.
Argeo Robotics AS, a fully owned subsidiary of Argeo AS which develops robotic and digital solutions for the ocean space, has been granted a patent from the Norwegian Industrial Patent Office for a subsea electromagnetic remote-sensing system.
The company has developed a portfolio of electromagnetic source and receiver systems for Autonomous Underwater Vehicles (AUV), Underwater Intervention Drones (UID) and ROVs. This patent protects Argeo’s exclusive services with the products Argeo Whisper and Argeo Discover.
Argeo Whisper is an AUV and ROV system developed for localising and tracking buried pipelines as well as detecting buried objects in a decommissioning survey. It can also be used for detecting unexploded ordnances.
Argeo Discover is an application or detecting, delineating, and characterising deep sea mineral deposits or other conductive objects below the seafloor utilising an electromagnetic source integrated in an AUV or ROV.
The company has developed an electromagnetic source that is designed to operate down to 6,000 m water depth. This technology enables ultra-high resolution characterisation of minerals that has previously not been possible. With Argeo Discover added to Argeo’s AUV and ROV sensor portfolio, Argeo is in a position to provide effective ultra-high resolution data acquisition for both larger regional and detailed local exploration over large areas with deposits utilising its fleet its AUVs rated to 6,000 m water depth.

The project for Argeo Searcher and both of the SeaRaptors is scheduled to commence directly after completing the vessel conversion project in January 2023 with a duration of 3-4 weeks and an estimated completion in February. The project has good possibility for extension further into Q1 2023.
The company will provide high resolution environmental and potential marine mineral resource assessment in addition to an advanced dual-AUV operation. Argeo will retain show and marketing rights for the data and present the results using its digital visualisation platform, Argeo SCOPE.
The recycling operation of Curlew, an FPSO vessel, has started in Vats, Rogaland, this week, with the 235 m-long ship loaded-in by a float-over and subsequent site move operation.
The vessel will now be cleaned, dismantled and at least 97% of it will be recycled.
This is the first time this type of vessel has been recycled in Norway. The production vessel, Curlew, was operated by Shell UK, and produced oil and gas from the Curlew field in the UK sector in the North Sea. The chosen decommissioning solution known as a float-over-float-in operation has never been used on such a large scale anywhere in the world. The contract was awarded to AF Offshore Decom through competitive tendering, and includes engineering, preparatory work, dismantling and recycling.
Dismantling and recycling of offshore installations and ships is an important part of the green transition. Here, Norwegian industry and engineering expertise have developed solutions that are at the forefront of the industry. This provides tangible evidence of the circular economy given nearly 97% of the ship can be used as raw materials in new production, with steel being used as rebar in new buildings, and all hazardous waste is taken out of the system and disposed of in a responsible manner.
“This is a very complex logistics project with significant marine operations. We are proud that we can carry out such complicated operations in a safe and environmentally sound manner," said Lars Myhre Hjelmeset, Executive Vice President for Offshore in AF Gruppen.
The production vessel Curlew has been in operation in the UK sector of the North Sea and was transported to the facility at AF Environmental Base Vats in Rogaland in 2020. The preparations on the FPSO have been ongoing at AF Environmental Base for some time, and the float-over-float-in-operation was completed this week. Now the ship has been transported ashore in the largest single offloading of a production vessel that has been carried out in this way. The hull is now safely located on the quayside at AF Environmental Base Vats, ready for cleaning, dismantling and final recycling. These activities will start immediately and continue throughout 2023.
“We have considerable experience in recovering offshore installations and floating production vessels is another area where our expertise and approach is both relevant and internationally recognised. Complex operations like this show that Norwegian offshore and engineering expertise helps set the standard for safe and environmentally sound solutions," commented Hjelmeset.
Treating and removing scale build-up within a tubing retrievable subsurface safety valve (TRSSSV) can be problematic, costly, and timely. For scale dissolvers to work effectively, they require extended soak periods to penetrate the scale.
To meet this problem, Oilenco has introduced the Oilenco Bullheading Jetting Sleeve which combines traditional soaking methods with a ‘jetting’ action, targeting scale dissolvers directly at critical components of the downhole safety valve, agitating the scale as well as soaking it?
Combining two tried and tested technologies, the new tool delivers optimum scale treatment results by using a repeated method of scale soak and targeted jetting.
Requiring minimal well intervention, this innovative product is designed to precisely target critical areas within the TRSSSV using a ‘jetting’ action to optimise distribution and efficacy of scale treatment. Designed with a minimum of two jet subs, the system is preconfigured to target key mechanical components within the TRSSSV before being deployed into the well on slickline.
Unique to the Bullheading Jetting Sleeve is the multi jet sub system. Each jet sub consists of an array of micro nozzles that create a 360⁰ jetting pattern. By positioning two or more jet subs at key locations within the safety valve (i.e. flow tube, exercise profile, flapper, etc.), scale dissolver can be precisely targeted at these critical areas.
Between each jet sub there is a flowrate sensing valve that directs fluid to either the upper or lower jet sub depending on the velocity of the fluid passing through it. When pumping stops, the jetting stops. When not jetting, the Bullheading Jetting Sleeve reverts to a conventional soak arrangement allowing the scale dissolver to soak into the scale. As soon as surface pumping is reintroduced, the jet subs become active and intense fluid agitation can recommence.
With constant replenishment of fluid, the system maximises performance of the scale dissolver in the most efficient time frame. Every drop of dissolver can be targeted at any critical area of the TRSSSV where scale build up could be affecting the functionality of the valve.
An ideal dual technology solution when scale build-up is identified as the likely cause of a TRSSSV not functioning, the Bullheading Jetting Sleeve (patent pending) is an innovative addition to the Oilenco safety valve management portfolio, re-establishing the integrity of a well and allowing operations to continue.
