Why Modularization ?

Reducing Risk and Interfaces , while optimizing cost (control )

� Global Sourcing;

� More quality � More quality

� More competition

� Better controlled fabrication

results in tighter tolerances

� Improved site infrastructure

Optimizing Transport design

■ Stowage forms

■ Vessel strength

■ Load out issues

■ Stability

■ Motions

■ Ballast capacity■ Ballast capacity

Example modular transports -piggyback

■ Quick load / discharge of barges

■ HTV not tied up for lengthy operationsoperations

■ Barges can go into shallow ports and rivers

Example modular transports –direct stowage on deck

■ Modules trailered or skidded on/off

■ Quayheight / waterdepth are critical during loadout

Loadout analysis - skid on

Critical parameters:

■ Waterdepth at quay

■ Quay height above water

■ Load spreading in HTVHTV

Load out analysis - roll on

Critical parameters:

■ Waterdepth at quay

■ Quay height above water

■ Load spreading in ■ Load spreading in HTV

Waterdepth and quay height

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.

Seafastening / Structural analysis

■ Accelerations during transit are important design factor

■ HTV motions much better than tug / barge

■ Designing for the right ■ Designing for the right transport vessel can safe a lot of steel in the module

Advantages of Heavy Transport Vessels

■ Carrying capacity

■ Sailing speed – reduced transit time

■ Cargo Safety

■ Better motion behavior → smaller accelerations / steel

■ Voyage Calculations

� Design Sea-state

� Loads on Cargo

Safety at sea

OCTOPUS Onboard - SPOS

with

Motion Monitoring

� Loads on Cargo

■ Safety limits/margins

� Statistical data

� Probability of Exceedence

■ What will be encountered in reality?

■ How will your vessels respond to waves?

Method – System description

sensor:

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

Purpose and Principles (2)

■ Safety increase

� more decision information for Master

� more insight in engineering calculation accuracy

■ Design improvements

� reduced design wave?� reduced design wave?

� generally accelerations are 50% or more below design values

■ Operational costs

� reduce weather delays

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 ?

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