10 State of the Art Installation Cycle abh sequential working steps with one main installation vessel loss of weather windows due to transport activities of the installation unit load out limited transport capacity acc. to max. elevated weight temporary storage of components at an additional base harbour as close as possible to site in order to minimize sailing time downtime for installation crew and equipment during sailing and loading sail to harbour installation of component s sail to OWP jacking up in harbour is mandatory for loading 10

11 Next Generation Offshore Windfarms abh parks in operation next parks consequences distance to shore 20 to 40 km 50 to 120 km increasing time per roundtrip turbine size 2.3 MW to 5.0 MW 6.0 MW to 8.0 MW increasing weight of foundations water depth 15 m to 25 m 25 m to 50 m increasing weight of foundations poor economics due to long sailing time and poor level of utilisation for equipment and human resources nearly all existing installation vessels can t handle next generation of foundations (m > 1000 t) logistical impact 11

12 Handling the Challenge abh splitting the process Construction Jackup-Platform permanent available on site installation activities only Offshore Construction Supply Feeder Vessel,OCSFV transport of components from shore to site installation of components in parallel to jackup max. utilization of weather windows high availability of components on site nearly constant installation progress parallelization in installation procedures 12

13 The Installation Process I abh field move to location 2 starting installation of next monopile offshore lift of monopile and transfer to jackup application of noise mitigation system pile driving with jackup OCSFV on stand-by position 13

14 The Installation Process II abh lifting and installation of transition piece grouting field move of OCSFV back to location 1 installation of scour protection 14

15 Scour Protection abh Conceptual design 1. Geotextile Sand Containers (GSC) as solution for scour protection 2. Design criteria: Diameter scour protection 4 times monopile diameter Two layers Container type E (B/l = 1,45 m / 2,38 m) Filling volume abt. 1m³ 3. Onshore preparation of complete scour protection package 4. Clearance hole for monopile already incorporated Scour Protection 2 layers D mp d SP = 4 x d mp 15

16 Scour Protection One Lift Installation abh lifting gear for Scour Protection Lift (preliminary design) connection lifting gear to supporting structure via levers Tensioning of supporting structure via levers a) tensioning by gravity b) tensioning by hydraulic cylinders a purpose-built net as supporting structure for the geotextile sand containers Net material: high modulus polyethylene Pending Patent Application DPMA 16

21 Introduction MARIN introduction MARIN expertise MARIN contribution to the project 21

22 MARITIME RESEARCH INSTITUTE NETHERLANDS Independent and innovative service provider for the maritime sector in hydrodynamic and nautical research 22

23 MARIN S ACTIVITIES Simulations Model testing Full scale Training 23

24 Maintenance & Support MARIN s activities in offshore wind Development Fabrication Transportation Installation Production Removal? 24

25 Maintenance & Support MARIN s activities in offshore wind Development Fabrication Transportation Installation Production Removal? 25

26 MARIN s activities in offshore wind Challenging phases where MARIN helps: Maintenance: Offshore maintenance JIP Logistics simulation tool Installation: Wind Jack JIP Impact loads on jack-up legs Operation: WiFi JIP Impact loads on fixed wind turbines Alternative to fixed offshore turbines: Floating wind turbines JIP 26

27 Limitation of Accessibility Models Only limited number of environmental condition are considered Wave direction Wave period Vessel hydrodynamics is not considered Transit phase Approach phase Fender friction Human criteria is not considered Sea sickness Human fatigue Performance 27/22 27

28 Offshore maintenance jip - objective Most suitable vessel depends on type of repair Inspection Service Maintenance Small repair Component repair Component replacement 28

29 Scope of work MARIN Improve models including Human factors Determine environmental conditions for the area modelled Simulating different logistical scenario s Hull optimisation of the OCSFV vessel 29

33 Questions 35

34 WP 5: Kinematic simulation of crane operation, Analysing crane operation according moving parts Modelling of the kinematic parts in geometry, mass and mass inertia ->getting a simulation modell for the critical processes Verfification of the model using simple model for testing and measuring 36

35 Input General drawing of the Vessel to model geometry (in best case a 3D Model allready exists?) Mass of the vessel and its components The carne with its moving parts in detail including mass. Moving of the vessel in sea is calculated by MARIN 37

36 Challenge During the crane operation heavy load is craned. The moving, acceleration of this mass is invluencing the moving beaviour of the vessel >A feed back to the cinematic process is needed Therefore the hydodynamic damping of the water is need but difficult to model in the system 38

37 Very Simple Kinematic Model 39

38 WP 5: Kinematic simulation of crane operation, As a result getting: the accuracy of positioning Acting forces Collisions In addition moving compensation allgorithms can be tested 40
