Finite Element Strength Analysis for ATB Load Box

Figure 1: View of Global Finite Element Tug Model.

The loading and response dynamics of an Articulated Tug & Barge (ATB) load box are complex. They typically require advanced finite element analysis methods and procedures to design an efficient support structure to ensure a durable design and to facilitate meeting Class strength requirements. To study the dynamic response of the loads imparted on the tug from the barge, a finite element analysis (FEA) is carried out. Loading conditions that include the static sea pressure, gravity loads, and reaction forces from the ATB Coupler are incorporated into the FEA analysis.

Meeting New Heated Cargo Vessel Regs

With the publication of the 2015 Rules for Building and Classing Steel Barges, ABS has amended the rules to require the submittal of a steady state temperature distribution for Oil Tank Barges that carry heated cargos at temperatures greater than 50°C (122°F) and a structural assessment to determine the resulting thermal stresses in barges where the steel temperature is expected to exceeds 50°C (122°F). While similar requirements have been in place for several years for chemical tank barges…
