METHOD FOR CONTROL OF TRIM OF TRANSPORT VESSEL WITHOUT BALLAST OF SEAWATER Russian patent published in 2022 - IPC B63B39/03 B63B43/06 

FIELD: transportation.

SUBSTANCE: invention relates to a method for control of trim of transport vessel (1) without ballast of seawater, having a length l along a transverse axis (y'y) of vessel (1). In this case, mentioned vessel (1) has weight P_v in an empty state from 20% to 60% inclusive of the total weight P_T, taking into account a given load capacity P_TC, according to the formula: P_T = P_v + P_TC, and it has at least one first and one second closed tanks (3' or 3") for liquid, not communicating with the sea, the total weight P_RT of which in a state of complete filling with liquid having a density equal to 1 is from 2% to 8%, preferably from 3% to 6% of the mentioned weight P_v in the empty state. At the same time, mentioned tanks (3', 3") communicate via at least one line for liquid transfer from one tank to the other, and they are located at a distance d from each other, taking into account a corresponding geometrical center of each of mentioned tanks (3', 3"), at least equal to ½, when tanks (3', 3") are located opposite to each other essentially along the transverse axis (y'y): d ≥ ½.

EFFECT: invention is aimed at solving problems of vessels without ballast of sweater by improvement or simple provision of seafaring properties of these vessels in the open sea or when entering port areas, and in port areas, in particular, it concerns vessels capable of transporting large amount or volume of cargo, for example, vessels for LNG transportation.
