Slide 14

• The installation schedule is based on installing approximately 110 km of 3LPP coated 12 inch pipe

• 30 km of flexible & umbilical & One manifold ~ 500 tons• Reeling operations are taken off the critical path • Continuous installation campaign from one multipurpose construction vessel• Overall duration of the project is shortened by approximately 15 days.

CONCLUSION• The effective rigid pipeline spooling time is off critical path compared to

traditional reel lay vessels

• Pipelay vessel transit time is reduced considerably compared to traditional reel lay vessel

• Lewek Constellation can lay multiple products, such as umbilicals (with large UTAs) , flexible (large bending stiffeners) and rigid flowlines (with PLETs & ILTs) and SCRs in one trip

• The effective usage of the Lewek Constellation or time spent in the field compared to traditional reel lay vessels is shorter on typical projects and ideal for the Northern North Sea that has a short weather windows and short effective installation windows available.

• Lewek Constellation is ideal for remote locations with a high weather sensitivity such as the Northern North Sea, Artic, Barents Sea, Brasil
