Accelerated Bridge Construction (ABC) Techniques for Heavy Lift (HL) & Materials Off-Loading Facility (MOF)

This paper explores how Accelerated Bridge Construction (ABC) strategies developed for regions of moderate to high seismicity are suitable for heavy-lift construction logistics wharves intended to serve new industrial projects such as LNG terminals in British Columbia. Many industrial facilities require a heavy lift construction logistics wharf for off-loading construction equipment and large preassembled process modules weighing thousands of tonnes each. The logistics wharf is often needed early in the project construction sequence, favouring the use of expedited construction techniques, consistent with maintaining suitable design and seismic performance criteria. This paper highlights aspects of the engineering design of the Heavy Lift (HL) Materials Off-loading Facility (MOF) to serve as a multipurpose deep water logistics wharf. The MOF will accommodate the simultaneous berthing of two large vessels: a RO/RO vessel, to accommodate multiaxle Self Propelled Modular Transporters (SPMT) off-loaded by the stern, and a heavy-lift general cargo vessel berthed on its side.
