10 Six Azipod CZ configuration Full-scale bollard pull test Exceeded contractual values about 10%

11 Introduction Subject vessel is DP3 accommodation / work barge The propulsion system m in length Breadth of 34 m and depth of 9.1 m. The maximum draft is 6.1 m The vessel was built in China 2017 Hull shape is basic pram type Three thrusters in the stern/bow respectively Side thrusters positioned ahead of center thruster Bollard pull requirement was 30 tons per thruster July 2, 2018 Slide 11

12 The thruster selection Specification called for a thruster w/ 1.8 MW capacity to achieve the 30 t bollard pull The vessel has 6 thrusters, three in the bow and three in the stern Side thrusters positioned ahead of center thrusters ABB was selected based on performance predictions Based on reference data it concluded there could be a 3-4% thrust loss for the side thrusters due to the configuration As a result the power rating was increased to 1.9 MW AZIPOD CZ980 Pushing podded thruster with a ducted propeller PM motor Prop diameter 2.4 m RPM is 301 at max power of 1.9 MW July 2, 2018 Slide 12

13 Bollard Pull Test at COSCO Zhoushan shipyard

14 Bollard Pull Test Preparations ABB recommendations based on ITS2002 Bullard Pull trial code Current, waves, water depth, water density Testing protocol, time and frequency Load cell arrangement and calibration Towing length Orientation of the vessel July 2, 2018 Slide 14

15 Bollard Pull Test Conditions COSCO Zhoushan Shipyard July 26 th 2017 Measured bollard pull every 30 seconds over 10 minute 4 tests completed as follows, 1) Centre pod in the bow (#5) 2) Side pods in the bow (#4 and 6) 3) Centre pod in the stern (#2) 4) Side pods in the stern (#1 and 3) Beautiful summer day in Shanghai! Testing the thruster in the bow! July 2, 2018 Slide 15

16 Bollard Pull Test Conditions Ocean Currents For Azipod thrusters 4-6 the towing line was attached to the bow with the vessel backing out. For Azipod thrusters 1-3 the towing line was attached to the stern. Current speed and direction was measured throughout the test Speed kts Direction relative to thruster ranging from ahead/port side stern/port side July 2, 2018 Slide 16

17 CFD Analysis to compensate varying current impact Impact of Ocean Current at 1.8 MW Power Current direction Current velocity (m/s) Pod open water thrust (t) From the front From the rear Side Opposite side kn current have about 2.5 tonnes impact on BP values July 2, 2018 Slide 17

18 Summary of Results with Thrust Deductions for Current Impact Pod # Static bollard pull (t) Current Impact (t) Adjusted Static BP (t) ~ ~ ~ ~ ~ ~ 33.3 Contractual bollard pull value 30 t was clearly exceeded with each Azipod thurster

19 Conclusions Bollard pull results in line with estimations Seldom opportunity to test BP of this size vessel CFD used to estimate influence of varying current Current adjusted static BP estimates very close to original CFD estimates Adjusted BP test results (including the current effect) indicate that the side thrusters (#1, #2, #4, and #6) produced a thrust that was 5-7% lower than the center thrusters (#2 and #5) Azipod Thruster # Static bollard pull (t) Current Impact (t) Adjusted Static BP (t) BP Estimate from CFD ~ cntr ~ ~ ~ Contractual bollard pull value 30 t was clearly exceeded with each Azipod thruster 5 cntr ~ ~ July 2, 2018 Slide 19

23 Azipod DZ operation experience Feedback from 1st Azipod DZ vessel in operation by Guangzhou Salvage Bureau Feedback from 1st Azipod DZ vessel Performance exceeded expectations on sea trial for both DP performance and transit speed Captain Shaohua Liu (Guangzhou Salvage Bureau): We are really impressed with the vessel s performance. Response time and maneuverability, both of which are critical in our operations, are excellent. Less power was required than we expected for a given function. The Azipod D has exceeded our expectations by far. No major warranty claims for any of the three operating vessel now after 4-5 months of operation. July 2, 2018 Slide 23
