“…Figure 1 shows the inner knuckle lines of a product oil tanker. In conventional design, geometric shape of inner shell is always represented by Figure 3, which is expressed by 2D sections and dimensioning (Chen et al 2010). This method based on 2D expression is not intuitive.…”

Currently, the subdivision method of bottom-up is used widely in the ship industry, which is timeconsuming and tedious as the ship consists of compartments of several tens to several hundreds. To improve the speed of subdivision, a new parametric subdivision method of the top-down approach based on constraints is proposed. The proposed method is based on space subdivision as if we cut a box into many small pieces. For this, several parameters (bulkhead and inner knuckle positions) are set to generate the subdivision polyhedrons to cut the hull and Non-manifold modelling technology is applied to generate solid model. Then the subdivision constraints are linked with the solid model and the subdivision scheme is optimised by constraints' knowledge, and the hold capacities can be calculated rapidly by this method. This method not only generates and modifies the solid model quickly, but can also reflect the designer's ideal vividly.

“…In the subdivision optimization or structure optimization methods for ship, the population-based methods are widely used in the existing literature, such as genetic algorithm (Chen et al, 2010;Olcer et al, 2006;Papanikolaou et al, 2010;Vasoncellos, 2010;Turkmen and Turan, 2007), and particle swarm optimization (Cui and Turan, 2010) etc. However, for the problem that has numerous extreme values, SISOM for example, it is very difficult for the population-based methods to avoid the premature convergence problem.…”

“…Ivanov and Wang (2007) proposed an simplified Still Water Sheer Force (SWSF) and SWBM calculating method, which is used in ship tank subdivision with the bulkhead positions as variables; Chen et al (2010) proposed a tank subdivision optimazation methods based on Genetic Algorithm (GA) to minimize SWBM under sequential ballast water exchange condition; Lin et al (1994) put forward a neural network expert system, which is applied for the intelligent design of ship and optimum tank subdivision. These researches are effective for reducing the maximum SWBM, but still, they have the following shortages:…”

“…The minimum longitudinal bending moment and shear force a the beam are the goals, and multiple safety criteria of the SBWE are used as constraints. The ballast water allocation optimization model of a gravity-flow composite ballast system and its efficient solution algorithm model improve the construction efficiency of crane ships and reduce energy consumption to provide theoretical and technical support, Chen et al 2 . A ballast water allocation optimization model and its efficient solution algorithm model of the ballast pump and gravity composite ballast system are established, which provides theoretical and technical support for improving the construction efficiency of crane ships and reducing energy consumption, Ju 3 .…”

To improve the space attitude adjustment efficiency of the robot designed in this study, the average water level height variation of each ballast tank during the rescue process and the ballast water filling mass before the rescue process are taken as optimization variables, the minimal ballasting time during rescue process as the optimisation objective, and the heel and trim inclination angle, and stability in the rescue process as the constraint conditions. For the first time, an optimization method of a rescue robot space attitude adjustment scheme based on a dynamic programming algorithm is proposed. Relevant experiments and data collection were carried out with a model robot with a physical ratio of 1:2. MATLAB simulation and model robot experimental results show that compared with an empirical scheme, the total deployment time and ballast water total allocation mass are reduced by 11.07% and 30.79%, respectively, and the heel and trim angle variation stability is increased by 4.18% and 8.67%, respectively. The optimization model and algorithm are beneficial to improve the space attitude adjustment efficiency and stability of the rescue robot in this paper, and it is also easier to transfer to other fields of ballast water allocation, which has strong practical engineering significance.
