Αλλαγές που αφορούν τους Έλληνες ναυτικούς, αξιωματικούς και πληρώματα, την περίοδο 1980 - 2024

Η ελληνική ναυτιλία αποτελεί διαχρονικά έναν από τους σημαντικότερους πυλώνες της ελληνικής οικονομίας και παγκόσμιας ναυτιλιακής βιομηχανίας. Η περίοδος 1980-2024 χαρακτηρίζεται από σημαντικές μεταβολές στον αριθμό και τη σύνθεση των Ελλήνων ναυτικών, τόσο στους αξιωματικούς όσο και στα πληρώματα.

Εξέλιξη του αριθμού Ελλήνων ναυτικών (1980-2024):

• 1980-1990: Κατά τη δεκαετία του 1980, η ελληνική ναυτιλία γνώρισε άνθηση, με σημαντικό αριθμό Ελλήνων ναυτικών να επανδρώνουν τα πλοία. Ωστόσο, συγκεκριμένα στατιστικά στοιχεία για αυτήν την περίοδο είναι περιορισμένα.

• 1990-2000: Η παγκοσμιοποίηση και η αυξημένη ζήτηση για φθηνότερα εργατικά χέρια οδήγησαν σε μείωση του αριθμού των Ελλήνων ναυτικών, καθώς πολλοί πλοιοκτήτες προτίμησαν αλλοδαπά πληρώματα.

• 2000-2010: Η τάση μείωσης συνεχίστηκε, με τους Έλληνες ναυτικούς να μειώνονται περαιτέρω, ιδιαίτερα στα κατώτερα πληρώματα, ενώ οι Έλληνες αξιωματικοί διατήρησαν σε μεγαλύτερο βαθμό τις θέσεις τους.

• 2010-2020: Σύμφωνα με στοιχεία, παρατηρήθηκε διπλασιασμός του αριθμού των Ελλήνων αξιωματικών που αποχώρησαν από τη θάλασσα και εργάζονται σε χερσαίες θέσεις, γεγονός που επηρέασε την επάνδρωση των πλοίων με Έλληνες αξιωματικούς.

  DealNews

• 2020-2024: Η έλλειψη Ελλήνων ναυτικών έγινε πιο αισθητή, με αποτέλεσμα να μην επαρκούν για την επάνδρωση των ελληνικών πλοίων. Συγκεκριμένα, αναφέρθηκε ότι αν εγγράφονταν 100 νέα πλοία στο ελληνικό νηολόγιο, δεν θα υπήρχαν διαθέσιμοι 600 Έλληνες αξιωματικοί για την επάνδρωσή τους, όπως απαιτείται από την οργανική σύνθεση πληρώματος.

Συμπεράσματα:

Η μείωση του αριθμού των Ελλήνων ναυτικών αποτελεί σημαντική πρόκληση για την ελληνική ναυτιλία. Η προσέλκυση νέων στο ναυτικό επάγγελμα και η αναβάθμιση της ναυτικής εκπαίδευσης κρίνονται απαραίτητες για την αντιστροφή αυτής της τάσης και τη διασφάλιση της συνέχειας της ελληνικής παρουσίας στη διεθνή ναυτιλία.

What is the formula for calculating the metacentric radius

What is the formula for calculating the metacentric radius

The metacentric radius (BM) is the vertical distance between the center of buoyancy and the metacenter of a ship[2][4][5][6]. The metacentric radius can be calculated using the formula BM = I/V, where I is the moment of inertia of the waterplane area of the ship around the axis of rotation under consideration, and V is the volume of the underwater part of the ship[4][5]. The metacentric radius is used to compare the stability of different vessels[2][5]. The metacentric height (GM) is calculated as the distance between the center of gravity (G) of a ship and its metacenter (M)[1][4][6]. The formula for calculating the metacentric height is GM = KM - KG, where KM is the height of the metacenter above the keel and KG is the height of the center of gravity above the keel[4][6]. The metacentric height is an approximation for the vessel stability at a small angle (0-15 degrees) of heel[1][6]. The metacentric height and the metacentric radius are both important parameters for a ship's stability, and they are used together to determine the stability of a ship[6].

What is the difference between metacentric height and metacentric radius

The metacentric height and the metacentric radius are two related but distinct concepts used in naval architecture to describe the stability of a floating body, such as a ship. Here are the differences between the two:

Metacentric height:

- The metacentric height (GM) is a measurement of the initial static stability of a floating body.

- It is calculated as the distance between the center of gravity (G) of a ship and its metacenter (M).

- A larger metacentric height implies greater initial stability against overturning.

- The metacentric height also influences the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers.

- The metacentric height is an approximation for the vessel stability at a small angle (0-15 degrees) of heel.

Metacentric radius:

- The metacentric radius (BM) is the vertical distance between the center of buoyancy and the metacenter of a ship.

- It can be calculated from the formula BM = I/V, where I is the moment of inertia of the waterplane area of the ship around the axis of rotation under consideration, and V is the volume of the underwater part of the ship.

- The metacentric radius can be used to compare the stability of different vessels.

- The metacentric radius is the radius of the circle for the movements of the center of buoyancy at small angles of heel.

In summary, the metacentric height and the metacentric radius are both important parameters for a ship's stability, but they are calculated differently and have different applications. The metacentric height is a measure of initial stability, while the metacentric radius is used to compare the stability of different vessels.

What is the metacentric height and how is it related to the angle of heel

What is the metacentric height and how is it related to the angle of heel

The metacentric height (GM) is a measurement of the initial static stability of a floating body, such as a ship. It is calculated as the distance between the center of gravity (G) and the metacenter (M), which is a fixed point determined by the geometry of the ship and the distribution of its buoyancy forces[2][3]. The metacentric height is an approximation for the vessel's stability at small angles (0-15 degrees) of heel[2].

The angle of heel of a ship is the angle between its upright position and the position it takes when inclined due to external forces. The metacentric height is directly related to the ship's stability and the angle of heel. A higher metacentric height generally indicates greater stability, while a lower metacentric height can lead to reduced stability or even instability[2].

The relationship between the metacentric height and the angle of heel can be seen in the curve of static stability, which is a plot of the righting lever (GZ) against the angle of heel. The righting lever is the moment created by the horizontal distance between the forces of gravity and buoyancy. The metacentric height multiplied by the sine of the angle of heel gives the value of the righting lever, highlighting the importance of the metacentric height to stability[6].

In summary, the metacentric height is a crucial parameter for a ship's stability, and it is related to the angle of heel through the righting lever. A higher metacentric height generally leads to greater stability, while a lower metacentric height can result in reduced stability or even instability.

How is the angle of heel related to the ship's center of gravity

How is the angle of heel related to the ship's center of gravity

The angle of heel of a ship is related to the ship's center of gravity in the following ways:

- When a ship is inclined through all angles of heel, the center of buoyancy shifts off-centerline while the center of gravity remains in the same location[4].

- The distance between the forces of buoyancy and gravity is known as the ship's righting arm, which is a perpendicular line drawn from the center of gravity to the point of intersection on the force of buoyancy line[4].

- For small angles of heel (0° through 7° to 10°), the value for the ship's righting arm (GZ) may be found by using trigonometry[4].

- The dynamic stability of a ship may be determined by measuring the area under the righting lever curve (GZ curve) up to a certain angle of heel[5].

- The larger the area under the GZ curve, the greater the ship's stability[5].

- The equilibrium trim angle is reached when the final center of gravity (G1) lies in line with the final center of buoyancy (B1)[3].

- Movement of any weight athwartship (in a transverse direction) will alter the position of the center of gravity of the ship (from G to G1), creating a heeling moment[3].

In summary, the angle of heel of a ship is related to the ship's center of gravity through the righting arm, which is the distance between the forces of buoyancy and gravity. The dynamic stability of a ship is also related to the area under the GZ curve, which is affected by the position of the center of gravity.

How is the maximum angle of heel determined for a ship

How is the maximum angle of heel determined for a ship

The maximum angle of heel that a ship can withstand depends on various factors, including the vessel's design, stability, and the external forces acting on it. Here are some ways to determine the maximum angle of heel for a ship:

- The angle of heel due to the combined effect of crowding, wind pressure, and centrifugal force should not exceed 12° in calculations[1].

- The curve of static stability is a plot between the righting lever and angle of heel, and the maximum righting lever (GZMAX), represented by point ‘B’ in the graph, is proportional to the largest static heeling moment that is required to bring the ship back to its upright position[2].

- The area under the GZ curve, up to a given angle, is proportional to the energy needed to heel the ship to that angle[3].

- The maximum righting arm is the angle of heel at which the maximum righting lever occurs[5].

- The estimated maximum angle of heel before equalization must be approved on a vessel required to survive assumed damage[5].

- The vessel's metacentric height (GM) must be at least 2 inches (5 cm) when the vessel is in the upright position[5].

- The maximum righting arm should occur at an angle of heel preferably exceeding 30° but not less than 25° [4].

- The final angle of equilibrium must not exceed 7 degrees after equalization on a vessel required to survive assumed damage with a longitudinal extent of 10 feet (3 meters) plus 0.03L, and it must not exceed 15 degrees after equalization on a vessel required to survive assumed damage with a longitudinal extent of 20 feet (6.1 meters) plus 0.04L[5].

In summary, the maximum angle of heel that a ship can withstand depends on various factors, and there is no single value that applies to all vessels. The angle of heel is limited by the vessel's stability, design, and the external forces acting on it. The maximum angle of heel can be determined by analyzing the vessel's stability and the external forces acting on it.

What is the maximum angle of heel that a ship can withstand

The maximum angle of heel that a ship can withstand depends on various factors, including the vessel's design, stability, and the external forces acting on it. Here are some relevant points from the search results:

- The "Law of 15's" is a rule of thumb that sets list/heel angle limits for Navy and Coast Guard surface ships[2].

- The angle of heel due to the combined effect of crowding, wind pressure, and centrifugal force should not exceed 12° in calculations[1].

- Fast displacement ships with Fn > 0.25 may feature dangerously large heel angles in turning circles, with the heel always outwards, i.e., away from the center of the turn[2].

- The estimated maximum angle of heel before equalization must be approved on a vessel required to survive assumed damage[5].

- The vessel's metacentric height (GM) must be at least 2 inches (5 cm) when the vessel is in the upright position[5].

- The maximum righting arm should occur at an angle of heel preferably exceeding 30° but not less than 25°[4].

- The final angle of equilibrium must not exceed 7 degrees after equalization on a vessel required to survive assumed damage with a longitudinal extent of 10 feet (3 meters) plus 0.03L[5].

- The angle of equilibrium must not exceed 15 degrees after equalization on a vessel required to survive assumed damage with a longitudinal extent of 20 feet (6.1 meters) plus 0.04L[5].

In summary, the maximum angle of heel that a ship can withstand depends on various factors, and there is no single value that applies to all vessels. The angle of heel is limited by the vessel's stability, design, and the external forces acting on it.

What is the angle of heel in ships

What is the angle of heel in ships

The angle of heel in ships refers to the inclination of a vessel to one side or the other, measured as the angle between the waterline and the deck[1][2]. It is caused by external forces such as wind, waves, or uneven loading of the vessel[5]. The angle of heel can have various effects on the stability and safety of the ship, depending on its magnitude and the vessel's design[2].

- The angle of heel due to the combined effect of crowding, wind pressure, and centrifugal force should not exceed 12° in calculations[1].

- Fast displacement ships with Fn > 0.25 may feature dangerously large heel angles in turning circles, with the heel always outwards, i.e., away from the center of the turn[2].

- The stability of a ship is significantly reduced due to the build-up of ice on its superstructure, causing unwanted angles of list and trim conditions[5].

To measure the angle of heel, a device that can sense the change in the ship's orientation relative to the vertical is used[6]. Monitoring and controlling the angle of heel is crucial for the safety and stability of the vessel, and appropriate actions should be taken to maintain it within safe limits.

What is the difference between angle of loll and angle of heel

What is the difference between angle of loll and angle of heel

The angle of loll and the angle of heel are two different concepts related to the stability of a ship. Here are the differences between the two:

Angle of loll:

- Occurs when a ship is in an unstable condition when upright, i.e., has a negative metacentric height.

- The vessel takes on an angle of heel to either port or starboard.

- The angle of loll is the angle of heel at which the vessel goes to neutral equilibrium.

- The angle of loll is determined by the values of GM and BM.

- A vessel at the angle of loll displays features of stable equilibrium, but it is a dangerous situation, and rapid remedial action is required to prevent the vessel from capsizing.

Angle of heel:

- Occurs when a ship is inclined to one side or the other.

- The angle of heel is the angle between the waterline and the deck.

- The angle of heel is caused by external forces such as wind, waves, or uneven loading of the vessel.

- The angle of heel is limited by the vessel's stability and the free surface effect of liquids on board.

- A vessel can return to its upright position after a heel, depending on its stability and the external forces acting on it.

In summary, the angle of loll occurs when a vessel is unstable when upright, while the angle of heel occurs when a vessel is inclined to one side or the other due to external forces acting on it.

Negative GM and angle of loll

Negative GM and angle of loll

The angle of loll is a term used to describe the unstable state of a ship when it is upright and has a negative metacentric height (GM) [1]. This means that any external force applied to the vessel will cause it to start heeling to either port or starboard[1][2]. As the angle of heel increases, the center of buoyancy moves out to a position vertically under the center of gravity, and the capsizing moment disappears[3]. Although a vessel at the angle of loll does display features of stable equilibrium, it is a dangerous situation, and rapid remedial action is required to prevent the vessel from capsizing[4]. The angle of loll can be determined mathematically by the values of GM, the metacentric height[5].
