聖勞倫斯型(英語:Seawaymax)是指一種北美規格的船隻,可以在通過美加的聖羅倫斯海道船閘的最大型隻。[1]

概述

聖勞倫斯型長度限制為740英尺(225.6米),船寬(寬度)限制為78英尺(23.8米),吃水限制為26.51英尺(8.08米),高度限制為海平面上35.5米(116英尺)。部分比此型號大的貨輪雖能在五大湖通航,但因受船閘大小限制,故不能經聖羅倫斯海道進出大西洋。船閘大小同時限制聖勞倫斯型噸位。最大噸位通過聖羅倫斯海道船隻記錄是一艘裝載28,502噸鐵礦貨輪,而最大噸位通過五大湖水道船隻記錄是一艘排水量72,351噸船隻。現時大部分新建在五大湖使用船隻按照此型號規格興建,以便於通過聖羅倫斯海道並在五大湖外航行。

在1975年沉沒埃德蒙德·費茲傑羅號是第一艘按此型號規格興建貨輪。

現時此型號主要用於把鐵礦、石灰岩及各種礦場運送至五大湖一帶工業區。在部分情況下,有使用此型號貨輪運載集装箱的可能。[2]
