Problems solved by technology

Optimal vessel speed must balance the benefit of slowing the vessel to save propulsion fuel with the additional electrical load impact on fuel consumption resulting from the excessive time required to make the voyage at a lower rate (i.e., the energy required to operate the necessary equipment). motivation) the associated costs of

Embodiment Construction

[0040] Certain terms used herein are defined as follows:

[0041] "LNG" means liquefied natural gas, which is generally cooled to at least a temperature at which the gas can assume a liquid phase at a pressure of about 1 bar; for liquefied methane, this temperature is about minus 162°C;

[0042] "Draft" may refer to the depth of water required to float a vessel; the depth below the waterline to the bottom of the hull of the vessel; and the depth of water drawn by the vessel. In this disclosure, "draft" may specifically refer to the depth below the waterline to the bottom of the hull of a vessel; and

[0043] "Trim" refers to the position of the ship relative to the horizontal; in other words, "trim" refers to the difference between the draft at the fore end of the ship and the draft at the aft end.

[0044] Whenever a ship is sailing at a given speed, whether carrying cargo or under ballast, the optimum trim and draft conditions for said ship exist. For ships in service, a l...

Abstract

A method for the reduction of ship fuel consumption through the optimisation of vessel draft, speed and trim using historical vessel data. Historical global, online data, is collected for multiple vessel operating parameters associated with its previous voyages. After initial filtering and cleaning of the gathered data, a process of analysing the data to determine the optimum draft, speed and trim for the vessels' given speed is described. The determined optimum draft, speed and trim values are then presented to the Captain or an automatic draft and trim optimisation system for the current draft and trim to be adjusted. This application therefore discloses a method for analysing historical vessel data to provide advice on optimum draft, trim and speed. A method for predicting the achievable fuel savings and recording the fuel savings achieved is also disclosed.

Description

technical field [0001] The present disclosure relates to a method for improving fuel consumption of a ship or ship-like by optimizing operational parameters. The present disclosure also relates to a method for collecting vessel data through various mathematical models and analyzing the vessel data to further determine optimal operational parameters. Background technique [0002] Typically, a vessel begins its voyage with a predetermined trim and draft, which then changes during the voyage due to internal transfers, such as fuel or lubricating oil transfers, and due to consumption and production of fresh water and other fluids. For liquid natural gas (LNG), liquid petroleum gas (LPG) and other liquefied gas cargo ships, the draft and trim will also change as the cargo is consumed through boil off gas (BOG). This draft and trim may not be optimal for the vessel's current speed. This non-optimal draft and trim condition results in increased drag, and in order to maintain a co...
