The invention relates to the technical field of ship construction, and discloses a polar region ice-resistant platform ice region reinforced region division method, which comprises the following steps: step 1, determining the ice level of a polar region ice-resistant platform: selecting the ice level of PC4 level or above in the PC specification; 2, ship body subareas are determined, wherein a ship body is divided into three areas in the longitudinal direction, namely a head area, a ship middle area and a tail area; the middle area and the tail area of the ship are divided into three reinforced subareas in the vertical direction; 3, ship body area factors are determined, wherein the ship body area factors of the middle portion and the tail portion are determined again according to IACS PC specifications, and the ship body area factors of the ice-resistant platform are divided into two conditions of tail-direction icebreaking and no-tail-direction icebreaking; 4, corrosion/abrasion increment of the outer plate is determined, on the premise that effective protection is adopted, the abrasion/abrasion increment value ts adopted when the thickness of the outer plate is determined again, the problem of standard applicability is solved, and the ice region reinforcing structure design of the polar region ice-resistant platform is more reasonable and safer.

本发明涉及船舶建造技术领域，公开了一种极地抗冰平台冰区加强区域划分方法，包括以下步骤：步骤1：确定极地抗冰平台的冰级：选取PC规范中PC4级及以上冰级；步骤2：确定船体分区：船体在纵向上分为3个区域：首部区、船中区和尾部区；船中区和尾部区在垂向上划分成3个加强分区；步骤3：确定船体区因子：中部及尾部的船体区因子按照IACS PC规范重新确定，将抗冰平台各个船体区因子分为有尾向破冰和无尾向破冰两种情况；步骤4：确定外板的腐蚀/磨耗增量：在采取有效保护的前提下，重新确定外板厚度时所采用的磨蚀/磨耗增量值ts，本发明解决了规范适用性问题，使极地抗冰平台的冰区加强结构设计更加合理及安全。
