7 AIR Environment friendly In the worst case you will have BUBBLES No additional medium Air compressor is already on board Easy to handle No dangerous situation for the crew or environment 7

8 Overview Pneumatic Overview Pneumatic piping Pneumatic feedback 8

9 Overview Electro/Pneumatic Overview 9

10 Ballast system 1. Air preparation 2. Marex AMC 3. Pneumatic Control Cabinet 4. Back up 5. Actuator 6. Tank measuring probe 10

11 Schematic overview Cargo management system Ballast water treatment Ballast pumps Electronic control & visualization Air conditioning and preparation Control cabinets Emergency operation Quick closing systems Actuator & Butterfly Ballast, bilge and fuel piping systems Scope of Supply 11

12 Unique design Competitor Pneumatic Solution Control Cabinet Internal electric wiring Our Pneumatic Solution Control Cabinet Power supply is not needed 12

13 Pneumatic feedback Feedback equipment Quick connection Pressure line Actuator control Benefits of the pneumatic feedback Generated directly from the actuator Fit for Atex & EX Robust No corrision No re-adjustment 13

14 Submerged valve Benefits of the Pneumatic submerged feedback Generated directly from the actuator Fit for Atex & EX Robust No corrision No re-adjustment Seawater resistance Easy to mount Fail - safe 14

15 Hydraulic feedback Low pressure (30 bar) central oil supply line create the position feedback Flow detector system Feedback needs to connect in line No independent position indication Flow indication Highly sensitive to low temperature Inaccurate Re-adjustment required Actuator When 2 actuators are operated at the same time, the position indication is not accurate Not safe 15

16 Hydraulic feedback Volumetric position simulation Hydraulics and electric components are used Volumetric cylinders are inside the control cabinet Two separate hydraulic systems are required The feedback will be simulated If BF valves are not connected, the cabinet will work without an alarm signal The actuator has no impact on the feedback Not safe 16

17 Original manufacturer Technical dates: Material Polyamide, Aluminum Vibration resistance 5 g Shock resistance 30 g Working pressure -0.9 bar / 10bar Control pressure 3 bar / 8 bar Temperature range -10 C / +60 C Particle size in compressed air 40µm Protection class IP65 Number of valves 24 / 26 Operation voltage 24 V small size robust handling price 17

18 Original manufacturer Data communication Digital input Analogue input Digital output Analogue output Field bus Aventics 18

19 Spare parts Spare parts: Cheap devices Easy to handle and mount Handling by the crew is possible No re-adjustment of the system Available 48 hours -> standard stock item Cost efficient 19

22 Commissioning Easy elimination of piping connection errors No additional material required Cost efficient Time - saving Environment friendly Realized through the shipyard Fully approved On request: SAP by Aventics 22

23 Benefits System price 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Hydraulic Price Price reduction 30-40% Pneumatic Financially attractive Low material costs Low installation/commissioning costs Easy to mount Average 30-40% price reduction Pneumatic operation/control Pneumatic position feedback of ballast valves No electric wiring in tanks Approved system Operating temperature down to -40 C Submerged active monitoring of valves in tank => Environment protection Technique Perfect addition to Green Passport 23

24 Comparison Systems Feedback Skill required Medium Submerged Environment Electrical o - + o + Hydraulic Pneumatic + + o

25 Comparison part II Systems Feedback Skill required Medium Submerged Environment Electrical power supply is necessary 2 systems (Elec/Pn/Hydr) Corrosion of contacts Not immersible Hydraulic and Pneumatics Electrical High Power Electrical necessary Possible but high risk and very expensive Corrosion Water ingress Hydraulic Pneumatic not a real feedback of the actuator position, because only the control pressure is measured only one feedback at the time possible A direct feedback of the actuator position is indicated Each actuator provides independent indication Every valve has a independent feedback Hydraulic and Pneumatics Electrical After a product training the shipyard can handle the system Oil pressure is necessary Tanks for oil are necessary an active power unit is necessary High- and Lowelectrical power is necessary only compressed air of 7 bar necessary YES YES High risk for the environment No pollution at all 25
