The document discusses modularization and heavy transport. It notes that modularization reduces risk and interfaces while optimizing costs. Dockwise specializes in transporting large modules by heavy transport vessels. These self-propelled vessels have advantages over tug and barge including larger carrying capacity, faster transit times, better cargo safety due to reduced motions, and allowing for smaller module steel sizes. Dockwise provides end-to-end logistical management and lumpsum solutions to transport modules from fabrication to installation sites. Early planning of transport is critical to project success.

13. Why Modularization ?
Reducing Risk and Interfaces , while
optimizing cost (control )
Global Sourcing;
More quality
More competition
Better controlled fabrication
results in tighter tolerances
Improved site infrastructure

14. Optimizing Transport design
■ Stowage forms
■ Vessel strength
■ Load out issues
■ Stability
■ Motions
■ Ballast capacity

15. Example modular transports -
piggyback
■ Quick load /
discharge of
barges
■ HTV not tied up
for lengthy
operations
■ Barges can go
into shallow
ports and rivers

16. Example modular transports –
direct stowage on deck
■ Modules trailered
or skidded on/off
■ Quayheight /
waterdepth are
critical during
loadout

17. Loadout analysis - skid on
Critical parameters:
■ Waterdepth at quay
■ Quay height above
water
■ Load spreading in
HTV

18. Load out analysis - roll on
Critical parameters:
■ Waterdepth at quay
■ Quay height above
water
■ Load spreading in
HTV

19. Waterdepth and quay height

20. Quay height and tide
■ If the quay is to high
the vessel can not
keep the deck in line
with the quay.
■ The vessel must ballast
fast enough to keep up
with the tide.

21. Seafastening / Structural analysis
■ Accelerations during
transit are important
design factor
■ HTV motions much better
than tug / barge
■ Designing for the right
transport vessel can safe
a lot of steel in the
module

22. Advantages of Heavy Transport Vessels
■ Carrying capacity
■ Sailing speed – reduced transit time
■ Cargo Safety
■ Better motion behavior → smaller accelerations / steel

23. Safety at sea
OCTOPUS Onboard - SPOS
with
Motion Monitoring
■ Voyage Calculations
Design Sea-state
Loads on Cargo
■ Safety limits/margins
Statistical data
Probability of Exceedence
■ What will be encountered in reality?
■ How will your vessels respond to waves?

24. Method – System description
■ System description

25. Purpose and Principles (1)
■ Decision Support - provide Master with:
expected motion response
real-time measurement of accelerations
■ Motion Monitoring
provide client with actual motion data
provide Engineering with data for:
validation of engineering tools
validation of long term statistics

26. Purpose and Principles (2)
■ Safety increase
more decision information for Master
more insight in engineering calculation accuracy
■ Design improvements
reduced design wave?
generally accelerations are 50% or more below design values
■ Operational costs
reduce weather delays

30. Conclusions and Recommendations
■ Early Concept Selection and Transporter Involvement
■ Designing Logistics into the Project
■ Think BIG
Reduce interfaces
What limits the size of the modules you can get to site?
■ Transport is critical part of the design !!!!
Dimensions – which vessels are available ?
Check load out facility – can we get in ?
Piggyback or direct stowage on deck ?
Float on, skid on or roll on ?

31. Conclusion:
Always plan ahead carefully…..!!!
