Outline
• Briefly about Van Oord• The Deltares-Van Oord plan• Basics of dredge production levels• Van Oord’s relevant experience in large projects• What do Deltares and Van Oord have to offer?
Van Oord Dredging and Marine Contractors bv
• Van Oord DMC is an independent, privately owned (family)business with a committed shareholder base
• Company history dates back to 1868• Owns and operates one of the world largest dredging fleets of
more than 400 units• Active all over the world (on average 200 projects in 50 countries
each year, 26 regional offices around the world, approximately4000 employees)
• Average turnover in the last four years over 1.6 billion Euro• Strong focus on innovation, engineering and D&C projects• One of the initiators of the Building with Nature research project
The Deltares-Van Oord plan (1)
The Deltares-Van Oord plan (2)
• This plan does not– help within a matter of days– presume to prevent all damage from oil pollution
• This plan does– help when the oil spill has to be combatted for
months– lower clean-up cost (beaches vs marshes)– provide longer term benefits
Modify the battlefield to make it easier to defend
Basics of dredge production levels (1)

Sailing
Excavation Disposal
Larger vessels reduce number of cycles needed!
More and larger vessels reduce construction time and cost!
Dredging with suction pipe Disposal option 1: Pump ashore
Disposal option 2: Dumping Disposal option 3: Rainbowing
Basics of dredge production levels (2)
Basics of dredge production levels (3)
• Tailor made execution strategy needs to be developedin close collaboration with US Government and USdredgers
• We expect in the order of 50 million m3 is needed• Jumbo (17,000 - 30,000 m3) and Mega (> 30,000 m3)
hoppers needed to get acceptable construction timesand cost!
• NB: World wide large reclamation made feasible onlybecause of large size hoppers

Deltares – Van Oord proposal
• Van Oord offers its unique capabilities to help USDredgers make the US Delta plan a success– Van Oord part of alliance with US dredgers to bring Delta plan
construction time within relevant limits– Van Oord engineering department and Deltares to collaborate with

Mississippi delta– Real-time modelling capability to optimize the design and focus the
dredging efforts according to ongoing developments– Eco-engineering knowledge to optimize the overall plan given the
characteristics of the natural system• We are ready to cooperate with you to take the next
steps
Feasible! How to proceed?
