How do you measure ship performance?
Monitoring of vessel performance
One of the ways is by measuring the daily fuel consumption and the daily distance covered. In this way, the daily mean power and mean speed may be calculated, and the result may be plotted in the speed/power diagram for comparison with the trial results.
What is ship Energy Efficiency?
Energy efficiency design index (EEDI) defines the energy efficiency of the ship by design. It is the ratio of CO2 the ship would emit per ton-mile of the work done by the ship. SEEMP is a ship specific plan that provides the ship specific measures that need to be implemented for energy efficient operations.
How should the energy efficiency of a ship be monitored?
Monitoring
1/Circ. 684). EEOI is Energy Efficiency operational indicator which can be determined by the fuel consumption of the ship in a particular voyage carrying a certain amount of cargo. Ccarbon is mass of the fuel to CO2 mass conversion factor of the fuel.
What is the unit of EEOI?
The Energy Efficiency Operational Indicator (EEOI) was developed by the IMO in order to allow ships to monitor the carbon emissions of their shipping activities. The EEOI is the total carbon emissions in a given time period per unit of revenue tonne-miles.
What is ship performance?
Kyma Ship Performance is a sophisticated solution for overall vessel performance monitoring. This system integrates the Kyma Power Meter system with advanced Windows based PC software that continuously monitors performance data.
What is shaft horsepower on a ship?
Shaft Horse Power: The horsepower delivered to a propeller shaft before being converted into thrust by the propeller. It is measured by an instrument known as torsion meter which is available on board. Sp = 2pient.
How is the efficiency of cogeneration measured?
Cogeneration efficiency is calculated by summing the useful electrical and thermal power output and then dividing by the fuel heat input. Well matched gas turbine cogeneration systems will achieve overall thermal efficiencies of more than 80% and, if there is a use for low-grade heat, the efficiency can approach 90%.
What is record of construction relating to energy efficiency?
Supplement to the International Energy Efficiency Certificate, a Record of construction relating to energy efficiency.
What is ship Energy Efficiency Design Index?
Energy Efficiency Design Index (EEDI), formulated for new ships, is an index that estimates grams of CO2 per transport work (g of CO2 per tonne-mile). It can be expressed as the ratio of “environmental cost” divided by “Benefit for Society”. In other words, It is a function of. • Installed power.
How can ships improve energy efficiency?
Operational measures to increase operational efficiency
These include slow-speed operation planning, higher capacity and resource utilization, and precise communication between shipping entities for efficient route planning. Reducing the turnaround time in ports is another way of increasing ship efficiency.
Why the efficiency of a boat is important?
More efficient vessels will help to keep prices – and emissions – down. ... “Even a slight increase in ship efficiency could dramatically reduce sea transportation costs and emissions, which would make the industry more competitive.
What is the sequence of events in the development and application of a ship energy efficiency management plan?
The SEEMP approach seeks to improve a ship's energy efficiency through four steps: ❖ Planning, ❖ Implementation, ❖ Monitoring, ❖ Self-evaluation and Improvement.
How can I reduce my EEOI?
The most direct way to reduce the EEOI is therefore to reduce speed. The slow steaming that is widely practiced today is therefore a very efficient way of reducing energy consumption. Yet, whether the slow vessel is more efficient when logistic, economic and other factors are also considered remains another issue.
What is IEEC certificate?
IEEC stands for International Energy Efficiency Certificate. It is a newly introduced certificate that is mandatory for all vessels of 400 gross tonnage and above. Contrary to most statutory certificates, the IEEC is not connected to a survey scheme and does not have an expiry date.
