a protruding bulb at the bow of a ship just below the waterline

The bulbous bow is a protruding bulb at the bow of a ship just below the waterline.

A forward protrusion below the waterline

A forward protrusion below the waterline is called a bulbous bow.

an extension of the hull just below the waterline

A bulbous bow is an extension of the hull just below the waterline.

a protruding bulb

A bulbous bow is a protruding bulb at the bow (or front) of a ship just below the waterline.

and economic-techno efficiency for seagoing ships such as increasing speed, decreasing fuel consumption, improving stability and seakeeping

A bulbous bow, which is a protruding bulb at the bow of a ship just below the waterline, is not only an effective solution to reduce the total resistance or required power of the ships, but also enhances safety and economic-techno efficiency for seagoing ships, such as increasing speed, decreasing fuel consumption, improving stability and seakeeping.

a very important part of the hull

The bulbous bow (bulb) is a very important part of the hull as the hull can potentially reduce the hull resistance considerably, or affect the resistance in a negative way.

wave-making resistances

In addition, a bulbous bow is introduced to reduce wave-making resistances.

the buoyancy of the front part

A bulbous bow increases the buoyancy of the front part and thereby decreases some of the up and down motion of the ship.

stable in heavy sea states

The ship has a bulbous bow that suggests a bulbous bow is very stable in heavy sea states.

a protruding bow

The Bulbous Bow is a protruding bow that is designed to break up the bow wave before the bow wave reaches the ship.

has speed and range to support long lasting missions

a bulbous bow has speed and range to support long lasting missions.

by creating an artificial wave, modifying the water flow around the hull, which reduces drag and increases speed and fuel efficiency

The bulbous bow works by creating an artificial wave, modifying the water flow around the hull, which reduces drag and increases speed and fuel efficiency.

most ships

A bulbous bow is the one that you will see in most ships including that used for commercial shipping.

the most common form for most commercial vessels

Bulbous bow: A bulbous bow is perhaps the most common form for most commercial vessels.

benefits

The bulbous bow provides benefits but also has an unpleasant side to an unpleasant side and thus has become somewhat controversial in recent years.

creating a wave that cancels the ship’s bow wave

Bulbous bows have traditionally been used for ships that mostly operate near their design speed by creating a wave that cancels the ship’s bow wave and reduces resistance by up to 15 percent.

an unpleasant side

The bulbous bow provides benefits but also has an unpleasant side to an unpleasant side and thus has become somewhat controversial in recent years.

normal part of modern seagoing cargo ships

Today the bulbous bow is a normal part of modern seagoing cargo ships.
