The aim of the project is to minimise the upcoming decommissioning bill for the tax payer and platform operators in Uk waters. Our main focus is on the highest cost share driven by the total integrated P&A costs. There is also a great opportunity in reducing the overall CO2 emissions by implementing an innovative technical solution instead of deploying overrated distressed drilling or workover units.We have identified a technical solution for P&A which finally focuses on the operator demand to deploy the right tool depending on the well and platform requirements. This modular multi-operational system is capable to be assembled in a basic setup to meet low well category requirements while it has the option to be upgraded if higher well categories are present. One of the biggest differentiator is its large operational envelope to existing workover solutions as it can serve all P&A campaign phases with the additional advantage of continuously recovering the old completion from the well without any breaks for connections. The system is light & compact as a workover unit while it has the operational flexibility of a drilling rig optimised to the most important P&A benchmarks such as the hoisting speed or handling of downhole tools.The feasibility study focuses on the commercial, technical and operational viability of the innovative disruptive technical solution. Main scope is the development of a basic design in a 3D software to support its technical feasibility. Afterwards, the 3D illustration will be converted to an animation for proving its operational capabilities, especially dealing with all necessary events in a P&A campaign from wireline jobs to completion recovery. This operability is transformed to the most critical benchmarks for a P&A job and compared to existing systems in an intensive commercial analysis by a P&A execution simulation tool. This tool proves operational capabilities, the comparative costs and emission savings in various setups, taking into account all aspects of P&A . The scope is to achieve a technical readiness level for the build of a demonstrator that will be deployed in a pilot project.

该项目的目的是尽量减少即将到来的退役法案的纳税人和平台运营商在英国沃茨。我们的主要关注点是由综合P&A总成本驱动的最高成本份额。通过实施创新的技术解决方案，而不是部署过高的受损钻井或修井装置，也有很大的机会减少整体二氧化碳排放。我们已经确定了P&A的技术解决方案，最终专注于运营商的需求，根据油井和平台的要求部署正确的工具。这种模块化多作业系统能够在基本设置中组装，以满足低井类别要求，同时如果存在更高的井类别，则可以选择升级。最大的区别之一是其对现有修井解决方案的大操作范围，因为它可以服务于所有P&A活动阶段，并且具有从井中连续恢复旧完井而不中断连接的额外优势。作为修井设备，该系统轻便紧凑，同时具有钻机的操作灵活性，可根据最重要的P&A基准进行优化，例如提升速度或井下工具的处理。可行性研究重点关注创新突破性技术解决方案的商业，技术和运营可行性。主要范围是在3D软件中开发基本设计，以支持其技术可行性。之后，3D插图将被转换为动画，以证明其操作能力，特别是处理P&A活动中从钢丝绳作业到完井恢复的所有必要事件。这种可操作性被转换为最关键的基准P&A工作，并在P&A执行模拟工具的密集商业分析中与现有系统进行比较。该工具证明了各种设置中的运营能力、比较成本和排放节省，并考虑了P&A的所有方面。其范围是为将在试点项目中部署的演示器的构建实现技术准备水平。
