Q & A
What is energy and how is it related to work?
-Energy is required to perform work, and it can come from various sources. It can be converted into different forms to carry out tasks.
What is fuel and why is it important?
-Fuel refers to a group of energy sources that usually require a chemical process to release or convert the energy they contain. It is essential because it provides the energy required for various processes, such as the propulsion of ships.
How do living creatures obtain energy?
-Living creatures obtain energy from food, which acts as a fuel containing chemical energy. This energy is released through the digestive process after food is consumed.
What are fossil fuels and how are they formed?
-Fossil fuels, such as coal, natural gas, and petroleum oil, are formed over millions of years from the remains of dead plants and animals. They are a common source of chemical energy.
Why is petroleum oil not suitable as a fuel in its natural form?
-Petroleum oil, or crude oil, is not suitable as a fuel in its natural form because it requires refining to convert it into usable products. It is also extremely valuable due to the wide range of products that can be derived from it.
What process is used to obtain fuels from crude oil?
-The process used to obtain fuels and other products from crude oil is called refining. Refining converts crude oil into various products, including fuel oils.
How have fossil fuels been used in the propulsion of ships?
-Fossil fuels have been used for ship propulsion since the steam engine and internal combustion engine replaced sails. Initially, coal was the main fuel, but it was later replaced by oil.
How is energy obtained from fuel oil on ships?
-Ships obtain energy by combusting fuel oil. Combustion is a chemical process that converts the energy content of the fuel into mechanical work to power the ship's propulsion system and onboard systems.
What types of fuel are most ships powered by today?
-Most ships today are powered by fuel oils derived from petroleum oil. These oils are used for both propulsion and other onboard systems.
What other issues are related to marine fuels besides their energy content?
-Besides energy content, marine fuels also raise health and environmental issues, which will be considered in detail in the module.

⚡ Energy Sources and Chemical Processes
Energy is necessary for performing work and can come from various sources, which can be converted into different forms. Fuel refers to a group of energy sources that require chemical processes to release the energy they contain. Living organisms need energy, which comes from food and is released through digestion. Fossil fuels, such as coal, natural gas, and petroleum oil, are also significant energy sources. These fuels are formed over millions of years from the remains of plants and animals, and this section introduces the topic of marine fuel oils derived from petroleum.
🚢 Evolution of Marine Fuels and Oil Refining
The second paragraph discusses the historical use of fossil fuels, particularly in maritime propulsion. Steam and internal combustion engines replaced sails, with coal being the initial dominant fuel, which later transitioned to oil. Crude oil, while valuable, is unsuitable for direct use as fuel due to its unrefined state. Through the refining process, crude oil is transformed into various products, including fuel oils. Modern ships rely on fuel oil for energy, powering both propulsion and onboard systems through combustion. The refining process, which extracts these fuels, and their properties, will be explored in detail, along with associated health and environmental concerns.

Highlights
Energy is required to do work and can come from many different sources.
Fuel is a group of energy sources that usually require a chemical process to release or convert their energy.
All living creatures need energy to live, and food serves as the chemical energy required by living organisms.
Food's chemical energy is released through digestive processes after consumption.
Fossil fuels like coal, natural gas, and petroleum oil are another common source of chemical energy.
Fossil fuels are formed over millions of years from the remains of dead plants and animals.
Ships have used fossil fuels for energy since steam engines and internal combustion engines replaced sails.
Coal was the primary fuel for ships initially, but oil has now become the main fuel source.
Crude oil, or petroleum oil, in its natural form, is not suitable as fuel and is highly valuable due to the range of products derived from it.
Refining is the process used to obtain fuels and other products from crude oil.
Fuel oils, derived from petroleum, are the main source of energy for the propulsion systems of most ships today.
Combustion of fuel oil is the chemical process that allows energy content to be converted into mechanical work on ships.
The refining process not only produces fuel oils but also other valuable products.

Energy is required to do work the energy may come from many different sources and
can be converted into different forms fuel is the term apply to a group of
these energy sources which usually require a chemical process to release or
convert the energy they contain all living creatures need energy to live
food can be thought of as the fuel containing the chemical energy required
by living creatures this chemical energy is released by the digestive processes
of the body after the food is eaten another common source of chemical energy
is a group of substances which are often referred to as fossil fuels these
include coal natural gas and petroleum oil they are referred to as fossil fuels
because they are formed over millions of years from the remains of dead plants
and animals in this module we will be looking at the properties of the common
marine fuel oils derived from petroleum oil and other issues relating to these
marine fuels
you fossil fuels have been used as the
source of energy for the propulsion of ships since steam and the internal
combustion engine replaced sail coal was the main fuel initially but this has now
given way to oil in its natural form petroleum oil or crude oil as it is
commonly referred to is not suitable as a fuel also it is extremely valuable
because of the vast number of products that can be derived from it these
include a group of products which are classed as fuel oils the vast majority
of ships in service today obtain the energy required to power the propulsion
system and other onboard systems through combustion of fuel oil combustion of the
fuel is the chemical process which allows the fuels energy content to be
converted into mechanical work the process which is used to obtain the
fuels and other products is known as refining we will briefly consider the
basic refining process before concentrating on the nature of the fuels
obtained from it including their properties in the rest of this module we
will also consider the health and environmental issues associated with
these fuels
