EXG Completes Transport for Green Hydrogen Energy Project

19th July 2024

EXG has proudly completed the transportation and load-out of 14 critical modules for the world’s largest green hydrogen energy project in Saudi Arabia.

Each module, weighing up to 250 MT, was meticulously moved and positioned using SPMT configurations comprising 48 axles and 2 PPUs with specially designed spacers.

The intricate operation involved transporting 14 heavy modules from their client's designated yard to the designated jetty using Self-Propelled Modular Transporters (SPMTs).

Module Specifications:

Number of Modules: 14
Weight Range: 250 MT
Each Module Dimensions: 50 (L) x 12 (W) x 18 (H) meters
Total Freight Tonnage (FRT): 1500 MT

Load Out Operations:

Roll-On/Roll-Off (RoRo) Operations:

- Modules Handled: 8

Procedure: The modules were securely loaded onto the RoRo vessel on SPMT using ramp plates and pre-placed stools. The vessel's stability was ensured with the ballast method. Once in place, the modules were thoroughly secured, making them ready for the voyage.

Lift-On/Lift Off Operations:

- Modules Handled: 6

Procedure: The remaining 6 modules were transported to the designated jetty on SPMTs, where they were Precisely lifted and placed on the deck by efficient crawler cranes.

Challenges Tackled and Solutions Implemented:

Innovative Spacer Combination: EXG introduced an in-house designed spacer combination for the SPMTs, resolving the Length & facilitating the loadout of PAR and PAU modules without compromising the integrity of the module structures.
Vessel Structure Protrusion: The company managed the higher loadout ramp height caused by vessel structure protrusions using Scheuerle axles. Continuous coordination with the vessel ballast team was essential in maintaining precise operational windows.
Precision Unloading: Their expert team achieved precision unloading on vessel grillages, maintaining a stringent 3% dimension clearance to meet sea voyage specifications.
Mooring Winches Limitation: EXG adeptly navigated the limitations posed by vessel mooring winches, successfully completing the loadout within a restricted rising tide window.
