1 Development in Dredge equipment in the last decade Ruud Ouwerkerk and Sergio Ooijens Dredging 2012, San Diego, 2012

2 A decade of progress Technology push and market pull Project demands Land reclamation Beach reclamation Port construction Waterway maintenance Land reclamation Lakes and reservoirs Mining Environmental Offshore dredging Higher efficiency Higher accuracy Higher uptime Etc. Regulations Project constrains Etc. New technologies For example: Larger vessels Improved dredging installations Etc. This presentation intends to illustrate a few items

3 Land reclamation and port construction High volumes and low cost price Economies of scale: larger vessels with higher technologies. Leading to a 50% reduction in USD/yr 3

4 Economies of scale

5 Larger hoppers with new technologies: The 40,000 cubic yard Congo River with a one man bridge, using artificial intelligence

6 Cutter suction dredge J.F.J. de Nul 2003 d Artagnan Ambiorix Athena 2012 Artemis- 2013

7 Some recent progress in dredge equipment illustrated WEDA 32 & TAMU 43 - June 11, 2012 Larger cutter suction dredges delivered during the last decades 7 Jumbo Class Cutter Suction Dredges GE DRED Characteristics LEONAR DO DA VINCI 1986 MASHO UR 1996 AL SADR 1999 JFJ NUL 2003 DE D ARTAGN AN AMBIORIX 2005/2012 ATHENA ARTEMIS 2012/2013 Tot. power inst. 20,532kW 22,380kW 20,507kW 27,150kW 26,200kW 24,702kW Cutter power 5480kW 2400kW 2200kW 6000kW 8160hp 6000kW 8160 hp 6000kW 8160 hp Dredge depth 32m 35m 27m 6.5/35m 35m 30.7m Manning Barge loading Yes No No Yes Yes Yes

8 Offshore dredging Extended dredging depth: up to 140 m

9 The larger dredges can go deeper. Smaller dredges can extend the dredging depth with the tele-tube

10 Dynamic trackig: higher accuracy

11 Cutterd dredgers working in waves

12 Development of dredge equipmentis no longer driven by economy WEDA 31 & TAMU 42 - June 7, 2011 DODO Simulation Software 12 Cutter suction dredge Athena s spud force analysis during dredging operations in simulated wave conditions

13 Can the limits be extended or at least safe guards be built in?

14 Conventional spud carrier csd JFJ de Nul

15 Longitudinally buffered spud carrier with wires csd d Artagnan / Ambiorix

16 D Artagnan - Spud carrier with wire compensation system

17 Just an impression to put man and machine in perspective: spud tilting

18 Spin-off for smaller standard dredges here: IHC Beaver 6518 ( a 26 discharge) the SPUD GUARD

19 Development of dredge equipmentis no longer driven by economy WEDA 31 & TAMU 42 - June 7, 2011 Spud Guard cylinders as mounted on the IHC Beaver step spud carriages 19

20 Waterway maintenance

21 The WILD DRAGON ready to go WILD DRAGON(left) Excavation drag head(right) s.g s.g. 1.08

22 Hull shape: 85 m vessels ton, ton, ton, ton, ton, 1999

23 Demand from the market: health and safety

24 Quarters isolated from noise and vibrations Manning: J.F.J. de Nul - 60 d Artagnan - 43 Athena - 50

25 Comfortable operating cabin also on smaller dredgers The engine and control cabin are placed on dampers for improved comfort and reduced noise.

26 Comfortable operating cabin: high efficiency Improved ergonomics for operating cabin and dredger controls; Unprecedented for the operator

27 Training New simulator technology Online learning

28 New technologies over the past decade, some highlights on the dredging installation

29 Medium Pressure Cutter Special High Pressure

30 Rock special design effort integrated with the Curve, a pump development to improve suction and wear of a complete pump

31 Wear resistant suction / discharge hoses Max Top Bucket Hose Bone Crusher hose with innovative steel rings, not tearing out

32 New cutter heads: the Lancelot cutter Not only on our standard cutters but also successfully implemented on a large mining dredge in Africa

33 Online monitoring Follow dredger activities from any place in the world Online support by experts

34 Development of dredge equipmentis no longer driven by economy WEDA 31 & TAMU 42 - June 7, 2011 CONCLUSION 34 The change in the market has created new technologies, but new technologies also have created new markets
