The Petroleum Safety Authority Norway (PSA) has given its consent for Aker BP to use the mobile drilling facility AKOFS Seafarer for well intervention activities on the Skarv field.

The AKOFS Seafarer is owned by AKFOS Offshore which undertakes well intervention and subsea installations in Norway as well as internationally.

Located in the Norwegian Sea, the Skarv field has been developed with a floating production, storage and offloading vessel (FPSO) with five subsea templates with 15 wells. Work is ongoing to evaluate the potential of infill wells and other prospects in the area due to a decline in production.

Pioneering Spirit, the world’s largest construction vessel, has removed the West Alpha and East Alpha structures from the North Sea’s Tyra field and will deliver them for recycling at Frederikshavn, Denmark.

The removal of the jackets concludes Allseas involvement in the Tyra Redevelopment Project. In total, Pioneering Spirit has removed more than 35,000 tonnes of offshore facilities from the field. The redeveloped Tyra II will continue the production of natural gas with 30% less CO2 emissions contributing to the energy security for Denmark and Europe.

2022 saw a record year for Pioneering Spirit. The vessel has lifted and transported approximately 115,000 tonnes of new and decommissioned facilities for the offshore energy industry.

Allseas’ role in the project covered engineering, preparation, removal and transportation to specialist dismantling yards of the complete East Alpha and West Alpha platforms, flare jackets, IPF and monopole.

Allseas has been awarded a major decommissioning contract by TAQA UK for the removal and disposal of multiple northern North Sea facilities.

The engineering, preparation, removal, and disposal (EPRD) contract comprises TAQA’s Eider Alpha, Tern Alpha, North Cormorant and Cormorant Alpha platforms. The combined weight of the topsides and jackets to be removed is around 114,000 tonnes, making this the largest single offshore UK Continental Shelf (UKCS) decommissioning contract scope to date.

Allseas’ task is to remove four platform topsides, three steel supporting jackets and transport them to a suitable onshore yard facility for dismantling. It is hoped that at least 95% of the materials from the facilities will be reused or recycled.

The platforms are located close to each other, approximately 100 kilometres north-east of Shetland, in water depths ranging from 150 to 167 metres.

All structures will be lifted and removed to shore as single units using Allseas’ heavy lift vessel Pioneering Spirit.

Platform removals are planned post 2025.

Independent drilling contractors, Stena Drilling, has introduced a new well delivery and decommissioning service, Stena Wells, with the aim of combining the renowned drilling contractors with an experienced team of well delivery experts with promises of consistently providing their clients with safe, cost-effective and predictable outcomes.

The vision laid out by the company is to join forces with a pre-constructed team to deliver and execute all client expectations. Previously, operators will source external well construction and decommissioning activities, with the team having to familiarise themselves with the rig and the internal operations. By having a team already formed with the predetermined understanding of how operations are delivered, Stena Wells wants to remove that learning curve to enable a focused approach to operations.

In a video posted on their LinkedIn, director of Stena Wells, Dillan Perras, said, “Stena Wells comprises of two main elements; these are the building blocks of what we are trying to do. The first building block is Stena Drilling, a well renowned, international drilling contractor. The second part of the offering is the Stena Wells engineering team that brings a wealth of experience, knowledge, capabilities and competence. Stena Wells will provide the planning, the permitting, engineering, notification, construction or decommissioning of any well stock.”

Spirit Energy Production (UK) ltd. has engaged ABL Group to provide marine warranty survey (MWS) and marine consultancy services for the operator’s decommissioning portfolio in the southern North Sea and the Irish Sea.

Spirit Energy has contracted ABL on a three-year contract (with three optional one-year extensions) to provide the marine warranty scope for the operator’s decommissioning campaigns.

ABL, which has provided a wide range of marine and engineering services for decommissioning operations in some of the world’s most complex offshore structures, will provide MWS services for decommissioning operations involving the removal of topside, and jackets for the following three offshore oil and gas platforms: Audrey A & B, and Ensign.

Ashley Perrett, Engineering Manager, ABL Aberdeen, commented, “ABL has considerable experience in supporting clients with the safe, efficient and optimised decommissioning of their oil and gas assets. Our long history in the sector, combined with our participation in a number of industry firsts within decommissioning, gives us unique insight into the range of challenges which can impact these complex marine operations.”

ABL’s MWS scope of work includes technical document and procedural review, on-site attendance and marine consultancy support for offshore operations during the campaign. Suitability surveying of the proposed fleet for the campaign is also part of the scope.

Saipem S.p.A (Saipem) and Oil Response Limited (OSRL) have signed an extension of their existing Services Agreement to include the provision of FlatFish, Saipem’s underwater drone for environmental monitoring and inspection of asset integrity.

The existing contract between Saipem and OSRL provides for the storage, maintenance, training of personnel and readiness including the remote emergency response of the Offset Installation Equipment (OIE). The OIE is a unique system designed to intervene in case of subsea well spills in shallow water (up to approximately 600 m water depth), when direct vertical access is not possible.

The expanded Services Agreement encompassed the deployment of FlatFish, the subsea drone developed by Sonsub, Saipem’s centre for underwater technologies and robotics, for a wide range of offshore tasks, including survey, leakage detection, through water column plume and dispersant concentration monitoring, environmental assessment and patrolling.

Furthermore, the Agreement allows Saipem to enlarge the fields of application of FlatFish, making a fundamental step towards its commercialisation on a global scale.

FlatFish is a part of Saipem’s Hydrone robotic development program, consisting of a series of subsea drones which are able to perform fully automatic inspection, surveillance, maintenance and rescue operations efficiently, safely and in an environmentally friendly manner. In particular, FlatFish is able to autonomously perform complex inspections of subsea assets, thanks to the robotic technologies it incorporates: from integrated artificial intelligence to advanced navigation.

At the OWI MED 2022 conferenee, Abdullah Moustafa Mohamed Saad, Senior Production Technologist, Cheiron/Bapetco, will explain how changes in conditions lead to low and zero coat production gains.

The conference will be held in Athens, Greece, on 20 September 2022. The hottest talking points within the Mediterranean and North Africa region, along with the latest well intervention intelligence from the region will be discussed at the event.

Abdullah will help the audience learn about closed in gas wells in heterogeneous reservoirs and explore how changes in stimulation cost unlocks more economic potential.

Through his presentation, he will make participants analyse artificial lift optimisation and cost changes and explain them the impact of reduced back pressures from years of production loss, that could help in intermittent operations.

Visitors at the event can explore well stimulation methods and effective production enhancement strategies to increase well stock value in mature wells.

OWI MED 2022 is back as a live event after last year’s inaugural virtual launch. The conference will be held in Athens, Greece, on 20 September 2022. The hottest talking points within the Mediterranean and North Africa region, along with the latest well intervention intelligence from the region will be discussed at the event.

Eman Sayed Shahin, Performance Lead and Senior Petroleum Engineer from Dragon Oil, will be presenting a case study on the success of advanced reservoir management via an integration between real-time monitoring system and classical reservoir model, in the Gulf of Suez.

She will review how the J-100 well was equipped with a real-time automation system, which helped detect problems in the well and reduce delays in receiving data from periodic visits to the well.

Eman will explore how this integrated work-flow highlights the integration between real time remote monitoring systems in offshore fields and how this can add considerable benefits to the business.
