1 The next step to more efficient and lean IRM vessels? Richard Myhre CEO and co-founder of AXTech AS Molde/RMY/

2 Agenda Evolution, vessels Module sizes Cost Factors Module Handling Vessel Stabilization Future opportunities

3 System capacity Growing in size: 20, 35, 60, 70t.. And now 420t! Open sea operating conditions Increasing: HS ,5 (latest) Vessels More and more specialized Multiple moon-pools Growing in size, Substantially larger >160m Cost Increasing peaked at 2014/15 Evolution of IMR module handling (Last 10 years)

4 Subsea modules in the North Sea More than 3000 modules Weights from <1 to 380t Modern MHS capacity: up to 70t Vast majority of modules: < 20t Only a very few above 60t Gullfaks wet gas compressor module (64t, 8,5x5x3m) Åsgard control power distribution units module 8,5x5x4,9m Typical small module

5 IMR operation cost drivers Factors for consideration: Vessels Lifting equipment (type, properties) Mobilization time Lifting capacity Operating sea state Crew ++ Large IMR vessels are still necessary to cover all current modules....but what if the smaller modules could be handled by smaller vessels with less crew, rented equipment and a very short mobilization time? and if the vessel could be taken from the currently inactive fleet?

6 New light module handling concept Quick mobilization and vessel independent No modification to the vessel Handle standard cargorails Allows for both Overside and moonpool operation Will cover well above 90% of all subsea modules in the North Sea 25t capacity Light Module Handling System - LMHS

8 Moonpool operation Same unit for overside and moonpool operation Fit most moonpools Extended cursor guide frame during moonpool operation

9 Integrated HPU and control system Versatile and flexible Fully integrated HPU and control system Mobilization within 48 hours Barge, truck or 40" container transport Rental, lease or purchase business model Available now..

10 IMR Vessel size and stability IMR vessel size and complexity growing over years Functionality, Capacity and Operating Sea State Enhanced stability can also enable the use of smaller vessels Reduction of vessel Roll and Pitch Enables the potential for variable buoyancy systems on offshore vessels Potential for use of smaller vessels at higher operational sea state Optimize vessel draft and ensure an efficient anti-heeling system Incorporate equipment properties and operational requirement into a central buoyance management system. In sum: Do more, with smaller vessels at higher sea states!

11 MRPC Active Stabilization System MRPC One option: Variable vessel buoyancy system Open ballast tanks to sea Air compressors will regulate seawater volume (also in vacuum) No need for fluid transfer between tanks Could potentially be linked with AHC lifting equipment vessel motion management system Redundant system Highly energy effective. Improve stability with up to 80% Effective in all weather conditions Certified and approved by flag state and class.

14 Summary Large and specialized IMR vessels are still necessary, but Increased focus on cost makes room for new ideas and concepts Compact systems and efficient vessels for smaller modules Technology demand challenges the industry for: New concepts for safer material handling between vessel and seabed Increased demand for more cost efficient and safe solutions More advanced technology utilized for optimized vessel and equipment performance. Q: Are vessel designers or shipyards the only ones to determine vessel performance?
