Historically, the seismic design of topsides structures like marine loading arms and cargo transfer hose towers has been done inconsistently and to a wide array of design codes and requirements. The root of this problem has been a forced reference to conventional building codes like the UBC or ASCE 7, which are poorly suited for marine structures and particularly to these kinds of installations. ASCE 61-14 has taken the first steps towards creating appropriate standards for seismic design of topsides structures. However, more needs to be done, and designers have learned valuable lessons about shortcomings that remain in the first edition of the new standard. This paper outlines the problems with existing seismic design codes and makes recommendations for changes to include in ASCE 61-19.
