Nowadays,with the increasing operational life of ships,the aging effects on their structural behavior need to be investigated *** the corrosive marine environment taken into consideration,one of the important effects of aging that must be studied is thickness *** this paper,with the use of previously proposed equivalent thickness formulations for corroded plates,the progressive collapse analysis software HULLST is enhanced,and then,the effects of different corrosion models of uniform,random,pitting,and tanker pattern types on the ultimate and residual strengths of a floating production,storage,and offloading vessel hull girder are evaluated for the ages of 0 to 25 *** reveal that the uniform corrosion and random corrosion models have close *** value of relative reduction in the ultimate strength of ship hull girder(compared with the intact condition)ranges roughly from 6%for the age of 5 years to 17%for the age of 25 years in the hogging *** relative reduction in the ultimate strength ranges from 4%to 16%in the sagging *** corrosion and tanker pattern(random)corrosion models lead to higher relative reductions in ultimate *** pitting corrosion model leads to a 16%–32%relative reduction in the ultimate strength for the ages of 5–25 years of the ship in either hogging or *** tanker pattern(random)corrosion model leads to a 6%–37%relative reduction in the ultimate strength in the hogging mode and 3%–31%in the sagging mode at ship ages of 5 to 25 years.
