2 What do we all know? P&A relevant for numerous fields Major focus on downhole challenges Important with suitable surface solutions Close cooperation between all parties is essential to succeed. Rolls-Royce data-strictly

3 What do we want to achieve? Improve HSE by safer & smarter solutions Improve efficiency Improve Working environment Automated solutions to eliminate manual handling as far as possible

4 What need to be done? Evaluate Topside handling solutions SIMOPs, working in parallel with drilling Feasiblilty study, covering handling, rig up and operational planning Define optimum solution with respect to safety, cost and benefit Detailed planning with potential use of 3D animations to optimize flexibility on smaller platforms.

5 Potential Solutions Intervention Solutions with Jack Modular WOU

6 Rolls-Royce data-strictly Pat pending Coiled Tubing Handling System have great flexibility

7 Pat pending Intervention solution w/ jack Tower wit integrated staircase Adjustable working platform for BOP deck, Injector Deck & to access Gooseneck in a safe and efficient way Main deck with foldable sides gives great flexibility Control cabin for all functions needed in P&A Junction box for all utilities, like electrical, hydraulic and requirement to hook up to platform Adjustable ISF in both directions (X&Y) Utility basket for return handling system Overhead crane under utility basket

8 By the used of working platforms as a riser handler BOP are connected without any lifting operation Pat pending BOP/Riser handling:

9 Automated BHA handling solutions Safe and reliable BHA handling No need for offshore crane Pat pending Tool handling:

10 Telescopic adjustable sub structure gives great flexibility to all platforms as it can fit across various range of skid beams and can also be adjusted to independent deck levels Pat pending Adjustable substructure:

11 The injector & BOP platform has an independent drive unit that can position the platforms at any position along the tower rack independently. Pat pending Safe working platforms:
