AI Technical Summary

Problems solved by technology

First, the installation of an oversized energy system leads to overall energy inefficiency
Second, the mass of fishing gear increases, and third, the onboard energy systems become more complex
Computer simulation modeling, simulation, and optimization are rarely used by designers because of the lack of advanced methods and design tools

Embodiment Construction

[0042] A ship's fuel consumption is determined by the combined action of the ship's mechanical systems, while being influenced by external conditions such as weather and currents. Considering that fuel costs are one of the largest expenses of a ship, it is important to manage and minimize fuel consumption in view of its negative impact on the environment.

[0043] In this context the following terms are used:

[0044] PLC Programmable Logic Controller

[0045] A set of standards used by OPC to communicate with PLCs and other devices

[0046] The OPC server handles communication with one or more PLCs, encapsulating the underlying protocol

[0047] OPC users connect to one or more OPC servers to read values ​​from or write values ​​to PLCs

[0048] NMEA National Marine Electronics Association Communications Standard

[0049] MetaPower is a torque and dynamics measurement system for rotating shafts.

Abstract

A method, computer program and system for optimizing the usage of energy sources on ships is disclosed. The method involves creating a computer simulation model of a ship, optimized for fuel efficiency. Creating the computer simulation model involves selecting equations from a pool of equations, describing core components and structural features of a ship, and data from a pool of characteristic data for ship's core components and structures. Moreover, a method, computer program, and system for optimizing fuel efficiency of ships by the use of a computer simulation model is disclosed.

Description

technical field [0001] The present invention relates to optimizing the use of energy. Background technique [0002] The major cost factors in the shipping industry are capital investment and operating costs. Shipbuilding is an expensive undertaking, the core investment decisions of which are made during the preliminary design phase and before the project is handed over to the shipyard. For example, the total construction cost to manufacture an 84 m long seiner is about 20 million euros. Based on this price, the design cost including preliminary design and final design is about 5% to 7% of the total cost. These design costs are low due to the fierce and persistent competition among consulting firms, but they only cover the main engineering design of the ship. Additional competition is emerging, such as Polish consultancies entering Western European markets with lower design prices. Until now, the response to this competition has been to increase the standardization of shi...
