Purpose of Lesson : 

Lessons gathered and identified during projects can be experiences, techniques or methods that provide benefit to future projects. These lessons can allow future projects to avoid undesirable situations, or equally provide guidance on positive experiences which can improve project outcomes. Both types of lessons become useful when they are shared and put into practice by the decommissioning community.

The lessons published on the Late Life Planning Portal focus on those lessons from which improvements to the tools and site can be identified, implemented and thus providing value to future projects.

We invite all our visitors to submit lessons which they feel could be helpful and useful to others who may be going through the same decommissioning process. If you feel you have a lesson that could be useful, please click the link below, fill in the details as requested and submit your lesson.

Once we receive a new lesson submission, we will review the lesson and keep you updated on the progress of the review.

L000010 The use of full engineering workpacks may not be appropriate during the execution phase of a project. Whilst it’s important to recognise that the purpose of a workpack is to provide adequate instruction to site personnel, this need not be so detailed that it inhibits the introduction of more efficient practices by an experienced construction team.

L000014 An operator’s experience has been that The Stakeholder Engagement Process worked well. It was reactive but fit-for-purpose. The NFFO, and DECC were consulted prior to commencement of the formal consultation process. Engaging with statutory stakeholders in advance of public consultation worked very well as it allowed us to receive comments from the NFFO and DECC on our proposals prior to the formal public consultation taking place. The lesson learned is that the Stakeholder Engagement Process with key regulatory bodies (DBEIS, OGA, NFFO) should be initiated early in the project for swift approval of decommissioning programs. The operator has documented the requirement to engage with statutory stakeholders in advance of public consultation. Also to make corporate affairs aware of the scope and detail of the conversations; the intention is that eventually all stakeholder communications will be managed via a web application. 5 TO 3 YEARS BEFORE CoP STAKEHOLDERS 7-3-2018 View

L000032 The sharing of, and acting upon, examples of good practice throughout the decommissioning process, including the late-life phase, has the potential to deliver significant cost and efficiency savings. The OGA, with the support of industry, has developed this on-line tool that shares good practice and learning in key areas of decommissioning. This microsite summarises still-evolving learnings perceived to improve decommissioning cost-performance. Though the applicability / effectiveness of these will vary, the options listed will typically merit consideration. The on-line tool will be updated with further learnings as these emerge. The lessons tool can be accessed via this link: http://www.lightcast.co.uk/oga-decom/ PRE LATE LIFE BUSINESS STRATEGY 6-12-2018 View
