HYDRO DECK
HYDRO DECK OVERVIEW
A mobile port solution, designed to serve as a bridging platform from vessel to quayside, the Hydro Deck is utilised for global projects faced with restricted offloading delivery windows due to unpredictable high tidal variations and where local port facilities are limited by scale or capability for a project’s specifications.
The Hydro Deck transports and offloads fabricated modules in adverse conditions, significantly increasing the availability of delivery windows. Its unique tidal buoyancy adjustment system provides clients with a greater range of ro-ro vessels and barges, improving both availability and cost competitiveness. This feature also allows the MOF to be built at higher elevations, therefore reducing the gradient to site.
The landmark innovation can be provided on lease, fully crewed with expert heavy lift operators, and, on completion of the load-in phase, it can be towed away, reducing upfront capital expenditure and environmental footprint.
The Hydro Deck offers our clients continuous offloading anywhere in the world, 24/7.

HYDRO DECK
Combining the very best in engineering design, mooring analysis and high-end fabrication, AG&P ALE Ventures Pty Ltd delivers an innovative solution to the offshore market to solve major logistical challenges and remove supply chain bottlenecks.
The first of its kind, the Hydro Deck has been designed and built through the joint venture between AG&P, a leader in integrated industrial process outsourcing and ALE, one of the world’s leading engineering and heavy lift companies.
The Hydro Deck is a transition pontoon that works in conjunction with modular offloading facilities (MOF) for on-shoring modules and infrastructure. Its innovative design enables load-in operations for combined loads of up to 17,000 metric tonnes, regardless of tidal conditions or port facilities.

HYDRO DECK SAFETY ADVANTAGES
• TIDE INDEPENDENT UNLOADING SOLUTION - The Hydro Deck provides a tide independent unloading solution. In the event there are problems during the ro-ro operations and the SPMT is partly on the ship or quay, the Hydro Deck can pump through the tide cycle allowing for a maximum safe situation for the problems to be rectified without compromising the operation.
• INTERNAL BALLAST SYSTEM - The internal ballast system has been designed with 100% redundancy. The deck of the Hydro Deck is clear of pumps, hoses and piping for flexible SPMT configurations and support stool locations. Internal ballast systems are far more reliable than external ballast systems because they are protected from the elements and permanently located, maintained and tested on regulated intervals inside the barge. External ballast
systems need assembly, testing and disassembly time for each operation and are susceptible to failure due to the exposure to the elements.
• FIXED RAMP SYSTEM ON EACH END - The ramp system has been designed for the maximum axle loads of the strongest SPMTs on the market to provide the safest possible ramp solution. Their hydraulic capability eliminates crane and/or forklift work, which are often the cause of an incident during a ro-ro operation. This feature also limits the exposure of the field personnel to the elements by eliminating tasks.

• CAPABILITY - 24 hours per day, 7 days per week, which can drastically improve the overall project schedule. Most of the Heavy Lift Vessels (HLV) are tide dependent, limiting unloading to 5-6 hours per day, sometimes only certain days of the month. The Hydro Deck eliminates the risk of costly demurrage costs and allows the HLV to focus on its role – going back to the fabrication yard for another load of modules.
• INCREASE IN COMPETITION - The Hydro Deck makes any HLV suitable for the job. Not many HLV’s are capable of compensating for these tides and their value to the project without the Hydro Deck will be at premium rates.
• EXTRA STORAGE AREA - The Hydro Deck provides 5600m2 of storage space on the deck of the barge to provide for the rapid unloading and release of the delivery vessel. This operation can take top priority to eliminate the risk of demurrage and provide the maximum output of the delivery vessel.
• DECK STRENGTH - The Hydro Deck has been designed for the delivery and staging of modules using support stools and SPMTs. With its 20t/m2 uniform deck loading and the high strength of the bulkheads, rarely will additional load spreading be required to self unload a module more than a normal support stool positioned by a forklift.

HYDRO DECK SERVICE TUNNEL
The service tunnel is an underdeck walkway between the two pumprooms. Utilising two pumprooms and two control rooms means that the Hydro Deck has 100% redundancy as one can take over the whole operation in case of an emergency in the other.
HYDRO DECK COMMERCIAL ADVANTAGES
• The internal ballast system is a sealed solution that enables water to be transferred from tank to tank within the pontoon. This eliminates the need to ballast water in or out of the Hydro Deck when catering for load transfer.
• Tide compensation is achieved by utilising the air system.
