■ Power: 27 MW (diesel electric)
■ Propulsion configuration: 2 Main propellers
(controllable pitch in HR Nozzle)
2 Retractable Azimuth thrusters
■ Speed : 14 knots
12. Target market A
■ Floating production structures:
TLP (integrated with topside)
Semi’s (integrated with topside)
Spar hulls
■ Gravity based production structures
■ Semi-submersible rigs
■ FPSO’s
■ FLNG
■ Semi-submersible crane vessels
■ Vessel dry docking
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
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

sensor:
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 ?
