What is HSFO and LSFO?

sulfur content. High sulfur fuel oil (HSFO) 3.5% Low sulfur fuel oil (LSFO)

What are concerns to change to lower sulphur fuels?

Typical technical problems experienced by shipowners when they are required to use low-sulphur fuels include issues with the supply and storage of lowsulphur fuel, problems with machinery operation when using low-sulphur fuel, incompatibility between fuel types, and difficulties and delays when changing over from one …

What is the required distance for the ships to change over to low sulfur content fuel?

200 nautical miles
Ships operating up to 200 nautical miles off of U.S. shores must meet the most advanced standards for NOx emissions and use fuel with lower sulfur content., This geographic area is designated under Annex VI as the ECA.

Which of the following is a hazard of the fuel changeover procedure?

Interruptions in fuel supply during the changeover process can lead to reduced engine power or in the worst case scenario, total loss of propulsion, which could be hazardous for the vessel, its crew, passengers and cargo.

What is DMA fuel?

DMA (also called marine gas oil, MGO) is a general purpose marine distillate that must be free from traces of residual fuel. This contamination with residual fuel usually occurs in the distribution process, when using the same supply means (e.g., pipelines, supply vessels) that are used for residual fuel.

What is Lsfo?

0.1% Low sulfur fuel oil (LSFO) Heavy fuel oils are referred to as low sulfur fuel oil (LSFO) if their sulfur content is below 1%. Usually these are marine fuel types IFO 180 or IFO 380, which have been desulfurized.

What percentage of sulphur in the fuel can severely reduce engine life?

U)* ERC concluded that a reduction of diesel fuel sulfur content from 0.27 to 0.05 weight percent would result in a 30 to 40 percent reduction in engine wear and therefore a 30 to 40 percent increase in engine life and oil drain interval.

Why is sulphur in fuel a problem?

Sulfur is a natural component in crude oil that is present in gasoline and diesel unless removed. Sulfur in gasoline impairs the effectiveness of emission control systems and contributes to air pollution. Reducing the sulfur content in gasoline enables advanced emission controls and reduces air pollution.

How can you reduce the sulphur content of fuel?

The new method uses a potassium salt to induce the chemical reactions required to remove sulfur from fuel. Potassium is an abundant element on Earth and cheaper and more environmentally friendly to use than rare metal catalysts that are used for similar reactions.

What do I need to know about 2020 IMO fuel sulphur regulation?

In 2020 a new regulation for a 0.50% global sulphur cap for marine fuels will come into force. Under the new global cap, all ships will have to use fuel on board with a sulphur content of no more than 0.50% against the current limit of 3.50% in an effort to reduce the amount of sulphur oxide.

What is change over procedure?

System Changeover definition. System changeover is concerned with the smooth shift from one way of doing things to another and the mitigation of disruption to business activities during the changeover. There are three main methods used: phased implementation, direct changeover and parallel running.

How do I change to HFO?

Fuel Changeover

  1. Reduce the load on the main engine to somewhere around 30 percent.
  2. Close the heating to fuel oil heaters and let the fuel temperature to approximately 100 degree Celsius.
  3. Keep the valve from the DO to the main fuel oil line open.
  4. Open the DO valve and Close the HFO.

How to change fuel oil to low sulphur?

The Isle of Man Ship Registry issures circular regarding Fuel change over procedures to Low Sulphur Fuel Oils as follows:

When to change from LSF to low sulphur?

Needless to say changing over of fuel includes several important factors under consideration. Every ship is provided with changeover Low Sulphur Fuel (LSF) calculator which tells the correct changeover time at which the system should be running on LSF before entering an Emission Control Area (ECA). This system requires some important factors –

Can a vessel burn low sulphur fuel oil?

In order to comply with the requirements of Regulation 14 of MARPOL, the burning of Low Sulphur Fuel Oils (LSFO) was introduced. Currently vessels are permitted to burn fuel oils with sulphur content of less than 3.5% whilst operating outside a SECA, but must ensure that they burn fuel with a sulphur content of less than 1% whilst within the SECA.

What should I know about fuel oil change over?

Note: Once the changeover procedure is completed, remember to change the HMI setting of Cylinder oil lubricator system (Alpha lubrication) or changeover the cylinder oil daily tank suitable for low sulfur operation. Looking For Practical Yet Affordable Maritime Resources?
