“…Длина машинного отделения L 3 во многом определяет его площадь и возможность размещения в нем главных двигателей и других механизмов, и устройств, размеры которых прямо или косвенно зависят от мощности главных двигателей. Анализ статистических данных позволяет получить следующую зависимость: (12) где N -мощность главных двигателей, кВт; a -эмпирический коэффициент, принимаемый равным 8,5 при низко-и среднеоборотных главных двигателях мощностью более 350 кВт и 7,0 -при средне-и высокооборотных двигателях мощностью менее 350 кВт.…”

This article is devoted to the development of the cargo carrying capacity evaluation method for a combined ship of tanker/platform type. A specific feature of cargo carrying capacity calculation for such ships lies in the fact that they have two cargo compartments of different structure. The compartments are interconnected, including dimensions, and influence each other. This fact leads to the need to update the existing calculation methods when justifying the main dimensions both of tankers and of platform ships. It is proposed to include the parameters which affect the cargo carrying capacity and take into account the above mentioned influence into the cargo carrying capacity equations. This article also specifies the determination methods for these parameters in the early stages of ship designing. All this made it possible to obtain relations, the inclusion of which into the mathematic model of optimization problem for main elements of a combined ship (tanker/platform type) allows proper evaluation of all available options of main dimensions in terms of their compliance with carrying capacity for each specific cargo as well as exclusion of improper options from consideration.

“…A conceptual design framework for collision and grounding analysis was proposed by Liu et al [3] to evaluate the crashworthiness of double-hull structures. The incidence of collision damage models on oil tanker and bulk carrier reliability was investigated by Campanile et al [4] by considering the IACS deterministic model against GOALDS/IMO database statistics for collision events, substantiating the probabilistic model. The progressive collapse analysis was performed by Muis Alie and Latumahina [5] for the local elements and the ultimate strength of a Ro-Ro ship.…”

The hatch opening has function to enter the load into the cargo hold. One of the ship type like this is Bulk Carrier. The hatch opening must be designed in suitable way because its influence to the ultimate strength since the hull girder under longitudinal bending moment. The application of the hatch opening on the ship’s deck should be considered for the ship design critreria. The objective of the present study is to analyze the ultimate strength with and without hatch opening subjected to longitudinal bending moment. The cross section of box girder is used to analyze the effect of hatch opening to the ultimate strength. This cross section of box girder is adopted for simple calculation. The application of Multiple Point Constrained (MPC) is adopted to analyze the box girder under longitudinal bending moment. The cross section of box girder is assumed remained plane during progressive collapse. The material such as density, yield strength, elastic modulus and poisson ratio are homogeneous. The type and dimensions of the stiffeners are also identic. The only one of the difference for the stiffener is number due to the hatch opening at the top of the box girder. It is found that the ultimate strength of the box girder with hatch opening is smaller than without opening one.

“…The simulation method is used in studies of the high-pressure fuel supply system of a marine diesel engine, taking into account the influence of weather conditions, the inertia of the vessel complex [3,4], wind-wave characteristics [5,6], etc. This makes it possible to obtain theoretical calculations of fuel consumption, optimal average velocity and other characteristics of non-stationary operating modes.…”

The high pressure fuel system is the fundamental system that forms the indicator of the minimum fuel consumption per unit of the vessel's path. The calculation of the optimal control of the vessel complex with the main diesel engine is performed according to the criterion of the minimum fuel consumption per unit path at a given average velocity of the vessel. The propulsion of a vessel with a main diesel engine is described by equations. The equations contain a significant number of parameters, the reduction of which is performed by introducing dimensionless quantities, followed by bringing the equations into dimensionless forms. This made it possible to present a solution to the optimal control law for the main vessel diesel engine as part of the vessel complex. Optimal control of the vessel complex under stormy navigation conditions has been investigated. The calculations of the control law of the vessel complex, which ensure the movement of the vessel with the maximum average velocity in conditions of stormy navigation, are presented. It is determined that the established law of control of the vessel complex ensures the minimum fuel consumption per mile at a given average velocity of its movement. The influence of a high-pressure fuel system on the optimal control of a vessel diesel engine has been investigated. Thus, the calculated studies indicate that for all values of the parameters of the vessel complex according to the law of control of the fuel system Ф=а+b∙C2(τ), they give fuel savings up to 6% per unit of way in comparison with the law of control of the vessel complex Ф=а+b∙(c1(τ)/c2(τ)). The obtained ratios during modeling and optimal control of the main diesel engine of the vessel complex allow using the dynamic programming method to analyze the fuel consumption per unit path with optimal control compared to the corresponding constant control
