The invention provides a ship bow linetype design method and a liquefied gas carrier. The design method comprises the steps that S1, the design waterline of the ship is determined; s2, the longitudinal section line, closest to the bow, of the ship is determined as a middle longitudinal section line, a preset inflection point is arranged on the middle longitudinal section line, and a preset distance is formed between the preset inflection point and the designed waterline; s3, an inflection point line is drawn, the preset inflection point is set as the starting point of the inflection point line, multiple intersection points are obtained after the inflection point line sequentially intersects with multiple longitudinal section lines of the ship bow, and the inflection point of each longitudinal section line is sequentially determined based on the multiple intersection points; s4, the lower part of the inflection point is an original longitudinal section line, and the upper part of the inflection point is a design longitudinal section line; and based on the multiple inflection points, the multiple design longitudinal section lines are drawn, and design of the ship bow line type is completed. On the premise that the empty weight of the ship is not changed, the wind resistance of the ship bow is reduced, and the energy consumption of the ship main engine power is reduced.

    本申请提供本申请提供了一种船舶艏部线型的设计方法及液化气船,所述设计方法包括:S1、确定船舶的设计吃水线;S2、确定船舶最靠近艏部的纵剖线为中纵剖线,在所述中纵剖线上设置预定拐点,所述预定拐点与所述设计吃水线之间相距预定距离;S3、绘制拐点线,并将所述预定拐点设为所述拐点线的起点,所述拐点线依次与船舶艏部的多条纵剖线相交后获取多个交点,基于多个交点依次确定每条纵剖线的拐点;S4、所述拐点的下部分为原始纵剖线,所述拐点的上部为设计纵剖线;基于多个所述拐点分别绘制多条所述设计纵剖线,完成船舶艏部线型的设计。本申请使船舶在空船重量不变的前提下,降低船舶艏部的风阻,减小船舶主机功率的能耗。
