2 2 Motion compensated platform for offshore installation Providing increased safety and workability Offshore Conference AVANS Hogeschool 10-November 2011 Maarten Kuijpers, Bosch Rexroth

3 3 Workability of Crane Barges

4 4 The Barge Master

5 5 Workability of Crane Barges Multiplying effect of long boom Large boom tip motion Swinging of the load M Small roll or pitch angle

6 6 Workability of Crane Barges 1:1 motion transfer M Translation of the load Heave

7 7 The Barge Master A New solution Using standard barge In Using between: standard Barge crawler Master crane Motion Compensator

8 8 New Solution for cranes

9 9 The Barge Master Crane barges and weather window Safety Weather downtime/workability Planning & costs Traditional solution - Reliable - Costly - Lacks flexibility

10 10 Applications Jack-Ups Cranes Competitors??

11 11 Applications Combination Bargemaster & Jackup s Extends use of jack-ups Load-In not required in sheltered water. Less mass on board of jack-up s Supply
