Goodluck guys

3 major effects of engine operation to oil

SPECIAL PURPOSE GRADE OF DISTILLATE INTENDED FOR EMERGENCY SITUATION

GRADE KNOWN AS MARINE GAS OIL (MGO), ITS GENERAL-PURPOSE MARINE DISTILLATE IT MUST BE FREE FROM TRACES OF RESIDUAL FUEL

GRADE KNOWN AS MARINE DIESEL OIL (MDO) IS ALLOWED TO HAVE TRACES OF RESIDUAL FUEL, WHICH CAN BE HIGH IN SULFUR.

GRADE THAT MAY CONTAIN RESIDUAL FUEL AND OFTEN A RESIDUAL FUEL BLEND.

NON-DISTILLATE FUELS, IDENTIFIED BY THEIR NOMINAL VISCOSITY RMA10 RME180 –

MEANING OF MEPC

The four samples we take during bunkering is for?

When the oil is used, and contaminated with acids, the TBN is

When the oil has a decent number of detergents, the TBN is

If CCAI is higher, this means

If CCAI is lower, this means

Fuel oils consist of about.-

Fuel oils have small percentage of -

In oil refining, breakdown of heavy carbons using heat and chemical means is called

In hydrocarbon molecules, the term "saturated " means

Marine residual oil are classed as distillate fuel –

Best description of Marine Diesel oil? -

Contaminants that may be present in crude oil

Contaminants that may be present during refining process

Contaminants that may be present when transporting fuel

Contaminants that may be present when fuel is stored

To remove as much catalytic fines as possible the residual fuel should?

It neutralizes acids that gets into the crankcase.

When fuel used has high levels of sulfur

Marine Engine operation has major effects on its lubricating oil such as?

IT Will Provide a good resource for trouble shooting.

What happens when the cetane number of the fuel is low?

Reducing Too much of sulfur content in diesel oil will cause

Improper fuel droplet size due to damaged injectors will require more heat to complete

The most significant fuel quality issue in the field is

What is the main cause to alter the viscosity of a lube oil?

Which of the following is not happens when fuel has water content is above 0.05%

Marine boiler water treatment is a procedure usually done by

It is used in boiler water treatment to precipitate dissolved calcium hardness salts

It is used to combine with the hardness salts converting them to hydroxide suspended solids.

It is used for raising pH of condensate and steam to a non-corrosive level.

It is an oxygen scavenger used instead of hydrazine where economy is of importance

It is used in boilers when suspect oil is present or as a sludge conditioner when high solids are experienced.

A colorless liquid at ordinary temperatures, reacts with oxygen, acting as a scavenger. –

It is necessary to lower the boiler water concentration by removing dissolved and suspended solids.

A number that indicates the effect of the temperature changes on the viscosity of the oil –

In viscosity test, the basic method used is to compare the ___________ of the used oil in relation to the fresh oil in a flostick.

The _______is used to compare the viscosity of the used lube oil with that of fresh lube oil of the same grade

This determines how a lubricant will wet and spread over a surface.

There are two primary types of viscometers.

A calculation based on density and viscosity of fuel

What should be kept for 12 months in a safe storage place (in a steel box) outside living quarters, away from heat, at normal room temperature as far as practicable & not exposed directly to sunlight?

Vessel sample shall be retained on board for

It represents a Uniform International Standard for petroleum measurements.
