The invention relates to an LNG ship liquid cargo tank bottom fixing tool which comprises a fixed supporting base and a plurality of semi-fixed supporting bases, the fixed supporting base is arranged in the center of the bottom of a liquid cargo tank, and the multiple semi-fixed supporting bases are arranged at the bottom of the liquid cargo tank in a sliding mode and distributed in a radial mode along the periphery of the fixed supporting base; the fixed supporting seat is used for fixing the bottom of the liquid cargo tank so as to guide low-temperature deformation centripetal shrinkage of the bottom of the liquid cargo tank; and the semi-fixed supporting seat is used for releasing the low-temperature cold contraction tensile stress at the bottom of the liquid cargo tank through sliding. The LNG ship liquid cargo tank can be effectively fixed, LNG cargoes in the LNG ship liquid cargo tank can be effectively borne, structural stress caused by cold contraction deformation of the bottom of the liquid tank can be effectively released after the liquid tank is filled with low-temperature LNG, the service life of the independent liquid cargo tank of the LNG ship can be prolonged, and the safety of the independent liquid cargo tank is improved.
本申请涉及一种LNG船液货罐底部固定工装,包括固定式支撑座和多个半固定式支撑座,所述固定式支撑座设置于液货罐底部的中心,多个所述半固定式支撑座滑动设置于所述液货罐底部且沿所述固定式支撑座的周围呈放射状分布;所述固定式支撑座用于固定所述液货罐底部以引导所述液货罐底部的低温形变向心收缩;所述半固定式支撑座用于通过滑移释放所述液货罐底部的低温冷缩拉伸应力。本申请能够有效固定LNG船液货罐及承载内部LNG货物,并能在液罐加注低温LNG后有效释放液罐底部冷缩变形带来的结构应力,有益于延长LNG船独立液货罐使用寿命及提高其安全性。
