Effect of Power Pack Unit on Modular Trailer Spine Beam Deflection

Arya, Manish / Chakraborty, Pratik / Dhawan, Munish

For Modularization projects in Oil and Gas industry, Transportation of Structures (i.e. Modules or Pipe Racks) through modular trailers is usually considered as an important activity. Two types of modular trailers, Self-Propelled Modular Trailer (SPMT) and Propelled Modular Trailers (PMT) are used for this purpose. As a part of structural analysis, Trailer deflections and stability are also checked. Excessive deflection of trailer can have adverse impact on transportation operation including effect on structural integrity and/or trailer stability. Power Pack Units (PPU) are considered as essential component of the trailers which provide motion and suspension power to SPMT and PMT. Typically those units are cantilevered from one end or both ends of trailer. Generally consideration of power pack weight in analysis results in lesser deflection of trailer, as effect of those load counteracts to the sagging deflection profile of the trailer. So in general, it is considered that exclusion of the power pack loads will yield conservative result. This chapter discusses how the weight of PPU can generate high trailer deflection and describes viable solution for reduction of such deflection and thus obtaining a favorable trailer profile necessary for safe modular transportation per given project parameters.
