Heavy Lift Vessels for Modular Transportation

• Heavy Deck Barges

– Shorter Routes

– Shallow Discharge

– Grounding Required (If barge designed for it)

• Heavy Deck Carriers

– Faster than Tug & Barge

– No Tow Line

• Heavy Lift Ships (Load On – Load Off)

– Smaller Modules that can be Lifted

– Fast Mode

• Semi Submersible Heavy Lift Ship (Roll On Roll Off)

– Highly Stable

– Long Routes

– Fast Mode

Modular Transport – Tug & Barge

Modular Transport – Heavy Deck Carrier

Modular Transport – Heavy Lift Ship (Lift On – Lift Off)

Semi-Submersible Heavy Lift Ship (Roll On Roll Off)

Planning at the Design Stage

• Designing module with consideration of static and dynamic loads for the intended vessel

– Matching the module to the structure of vessel

– Taking into account the motions of the vessel and module, given the proposed route

• Vessel selection – classed, sufficient deck space and strength, motion response adequate to not overstress the cargo

• Project management team

• Fail to Plan – Plan to Fail

– Expense for matting / grillage

– Vessel or cargo damage

– Project delays

– Vessel modifications

Planning & Engineering - Heavy Lift Modular Transportation

Load Planning • Height of dock above water at low and high water

• Water depth

• Tidal conditions – use the tides when you can

• Live load or dead load

• Weight control and center of gravity

• Dock strength

• Vessel deck load capacity

• Vessel structure – frames and bulkheads

• Ramps / transition plates

• Load plans

• Stow Plans

• Ballast Plans

• Mooring plans

• Sea Fastenings / Tie Downs

Planning & Engineering - Heavy Lift Modular Transportation

Transport Planning • Voyage Plans

– Route

– Met Ocean Data / Studies

• Sea state for season & environmental conditions for route

• Vessel heading and speed

– Vessel Structure Analysis

• Motions Analysis

• Stability of the vessel

– Reactions between the vessel and cargo

– Ports of Shelter

– Bunkering

– Assist tugs

– Depths and air height

– Transit Ballast Plans

Planning & Engineering - Heavy Lift Modular Transportation

Discharge Planning

• Same dock and water considerations as load site

• Roll off or lift off

• Live or dead discharge

• Grounded Discharge

– Beach landings

– Shallow water

• Offshore Discharge

– Float over deck Installation

– Heavy lift installation vessel lift off

– Float 0ff (For Vessels being Transported by Semi-submersible Vessels

• Ballast Planning

• Weather window for removal of sea-fastenings and cargo

Planning & Engineering - Heavy Lift Modular Transportation

Risk Management

• Risk Assessment

– Sea State

– Routing Plans

– Safe Ports of Refuge

– Piracy

– SIMOPS

– Cargo Handling

– Suitability of Load & Discharge Sites

– Quality & Capabilities Analysis of Vessels

• Risk Mitigation
