AAL Shipping has successfully transported three heavy lift LNG plant modules from Hai Phong, Vietnam, to British Columbia, showcasing AAL’s service for large-scale energy infrastructure projects around the world.  It also marks the carrier’s most recent sailing on the Pacific trade – a route it is eyeing for greater regularity in support of market demand.

The cargo included two vertical flare stacks, critical for combusting unwanted gases and reducing greenhouse gas emissions.  Measuring over 50 metres in length, the flare stacks required highly specialised stowage and handling.

The heavy lift AAL Bangkok, part of AAL’s S-Class multipurpose vessel fleet, was chosen for its capability to transport oversized and heavy-lift cargo.  With a maximum lifting capacity of 700 metric tonnes, three spacious holds, flexible tween decks and an expansive weather deck, the S-Class vessel ensured the safe and efficient delivery of the modules.

Due to the length and height of the largest modules, the vessel’s hold configuration was particularly tight.  Two tweendeck panels were strategically repositioned at a higher level, allowing engineers to place two of the larger modules directly onto the tanktop.  There was clearance of one metre either end for lashings and sea fastenings, and just 50 millimetres beneath the repositioned tweendeck panels.

An unforeseen change in plans for the discharge of the modules presented logistical challenges and operational constraints.  Despite this setback, through careful planning and close collaboration with local stakeholders, the modules were successfully discharged.

Yahaya Sanusi, Deputy Head of AAL’s Transport Engineering department explained, “Precise cargo surveys enabled stowage of the two largest modules on the tanktop with only 50 mm clearance to repositioned panels, ensuring safe sea fastening and compliance with stability requirements.  This operation demonstrates our ability to handle challenging dimensions and weights on tight schedules.”

Henrik Hansen, General Manager of AAL Americas added, “This operation also showcased AAL’s re-entry into the ‘Asia – North America Pacific Trade’ with increasing traction along this vital trade route. We are in a position to provide customers trading this route with highly competitive solutions – something we have already demonstrated with our popular ‘Asia – US Trade Lane Service’ that provides monthly regularity to the USEC and US-Gulf regions.”
