SEAM1 -- Katipunan- assign students to explain or report this , tell them this is what OBE means the teacher not stud ang bida 1\. CAMBER ----curvature of the deck transversely. 1\. Camber: Camber is the slight [upward curvature] given to a ship\'s decks or to a horizontal surface like a beam or plate. It helps with water drainage, preventing water from accumulating on the deck or surface. Question: What is \"Camber\" in the context of ship construction? a) The overall width of the ship at its widest point b) The angle at which the ship\'s hull plate departs from the vertical c) The slight upward curvature given to a ship\'s decks or to a horizontal surface d) The vertical distance from the keel to the waterline Answer: c) The slight upward curvature given to a ship\'s decks or to a horizontal surface The purpose of camber in ships, particularly in decks and certain structural elements, serves several important functions: 1. Drainage: One of the primary purposes of camber in ship decks is to facilitate effective drainage. The slight upward curvature of the deck helps direct water towards the ship\'s scuppers (drainage openings), preventing water from pooling on the deck. This is especially critical during rough weather conditions or heavy rain, as it ensures that water is quickly and efficiently channeled away from the working and living areas on the deck. 2\. Rise of Floor (or Deadrise): The rise of the bottom shell plating line above the base line. This rise is measured at the line of molded beam. Large cargo ships often have no rise of floor.e 3\. Tumblehome is a term used in naval architecture to describe the inward slope or curvature of a ship\'s hull at or near the upper part of the ship\'s sides. It refers to the narrowing of the hull as it rises above the waterline. In other words, the upper part of the ship\'s sides slopes inward towards the centerline of the ship. Tumblehome is the opposite of flare, which is the outward curvature of the hull. Historically, tumblehome was a common feature in wooden sailing ships, especially during the Age of Sail. It was incorporated into the design to achieve various benefits: 1. Stability: Tumblehome helped lower the ship\'s center of gravity and provided greater initial stability (draw at camber)e 4\. The flare in ships refers to the outward curvature or widening of the ship\'s hull as it rises above the waterline towards the upper part of the ship\'s sides. Flare is the opposite of tumblehome, which is the inward slope of the hull. Flare in ship design serves several important functions: 1. Buoyancy and Stability: Flare increases the buoyancy of the ship\'s hull, particularly in the forward sections. When the ship encounters waves or rough seas, the flared shape helps lift the bow, reducing the impact of waves and providing a smoother ride. The added buoyancy also contributes to the ship\'s stability, especially in adverse weather conditions.e Flare in Ships (sexy) Flare is defined as widening the hull section from bottom to top. In other words, the increase in the breadth from the base and gradually towards the deck level. So, when we speak of flare, we can say that the hull\'s width or cross-section is greater at the deck level than the water line ![](media/image2.png) *Sheer* is defined as Curvature of decks in the longitudinal direction. Measured as the height of deck at side at any point above the height of deck at side amidships. - The deck sheer helps in preventing the entrance of waves and is taken into account when establishing the load line in accordance with international conventions.(same LOA) PARALLEL MIDDLE BODY ---- The straight part at the center of the ship where the water lines and buttocks have no curvature; that is, where all the fore and aft lines are parallel. MIDSHIP SECTION ---- A transverse section exactly half way between the Forward Post and the After Post Almost invariably, this is the widest part of the ship. PARALLEL MIDDLE BODY ---- The straight part at the center of the ship where the water lines and buttocks have no curvature; that is, where all the fore and aft lines are parallel. LENGTH OVER ALL (L.O.A.) ---- The total length of the ship from one end to the other, including bow and stern overhangs. molded depth ============ the vertical distance from the top of the keel to the top of the upper deck beams amidships at the gunwale (same draw at camber) DEPTH ---- The height of the ship at the midship section from the base line to the moulded line of the deck at side (underneath). DRAFT (Moulded) ---- The height from the base line to the load water line. FREEBOARD (Moulded) ---- The difference between the moulded depth and the moulded draft. (It is the height of the side of the vessel which is above the water when she floats at her load water line). (same draw as camber) TUMBLE HOME ---- The amount the top of the side shell slopes back toward the centerline between the point of widest breadth and the deck at side [(see Fig. 3)](https://purgit.com/wp-content/uploads/2010/02/fig_03.jpg) SHEER ---- The curvature of the deck at side as shown in the profile. The amount of sheer forward is the difference in height between the deck line (at side) amidships and the deck line at the forward end [(Fig. 4)](https://purgit.com/wp-content/uploads/2010/02/fig_04.jpg) The amount of sheer aft is the difference in height between the deck (at side) amidships and the deck at the after end. The line of the deck at center, in the profile, is higher than the line of the deck at side, owing to the camber, or transverse curvature of the deck. In [Fig. 4 ](https://purgit.com/wp-content/uploads/2010/02/fig_04.jpg)is illustrated the difference between the deck at the side and the deck at the center, owing to camber. The camber curve, as usually designed, is a circle of very large radius, but sometimes it is made as a series of straight lines, as in [Fig. 5](https://purgit.com/wp-content/uploads/2010/02/fig_05.jpg). The camber curve is the moulded line of the deck FORWARD PERPENDICULAR (F.P.) ---- A vertical line at the point where the load waterline crosses the foremost part of the moulded surface.(draw yes) AFTER PERPENDICULAR (A.P.) ---- A vertical line usually at the after end of the rudder post. If there is no rudder post, it usually is taken at the center of the rudder stock..(draw yes) LENGTH BETWEEN PERPENDICULARS (L.B.P.) ---- The distance from the forward perpendicular to the after perpendicular. To the designers, this length is very important, since upon it largely depends the amount of power needed to drive the ship..(draw yes) LENGTH OVER ALL (L.O.A.) ---- The total length of the ship from one end to the other, including bow and stern overhangs..(draw yes) MIDSHIP SECTION ---- A transverse section exactly half way between the Forward Post and the After Post Almost invariably, this is the widest part of the ship. https://maritimepage.com/different-parts-of-ship-and-its-function-an-easy-guide/ DEADRISE ---- The rise of bottom. It is the difference in height between the base line and the point where the straight line through the bottom flat surface intersects the vertical line through the side of the moulded surface at its widest point. [(See A and B in Fig. 1](https://purgit.com/wp-content/uploads/2010/02/fig_01.jpg); also, [Fig. 3](https://purgit.com/wp-content/uploads/2010/02/fig_03.jpg) BEAM --- The width of-the ship (moulded surface) at the widest point. [(See Fig. 3)](https://purgit.com/wp-content/uploads/2010/02/fig_03.jpg) ![](media/image4.png) ![](media/image6.png) ![](media/image8.png) ![](media/image10.png) ![](media/image12.png) Ship dimensions and form play a crucial role in determining a vessel\'s stability, performance, cargo capacity, and overall efficiency. Ships come in various sizes and shapes, depending on their intended use, and are classified based on their dimensions and form. Here are some essential aspects of ship dimension and form: 1. Length Overall (LOA): The Length Overall is the maximum length of the ship from the forwardmost point to the aftermost point, including any overhanging structures or appendages. 2. Length Between Perpendiculars (LBP): The Length Between Perpendiculars is the length of the ship along the waterline, measured from the forward surface of the stem to the after surface of the sternpost. LBP is often used to determine the vessel\'s cargo-carrying capacity. 3. Beam (B): The beam is the maximum width of the ship at its widest point. It is measured perpendicular to the centerline and determines the vessel\'s stability. 4. Depth (D): The depth is the vertical distance from the ship\'s keel to the uppermost continuous deck at the side of the hull. 5. Draught (T): The draught is the vertical distance between the waterline and the deepest part of the ship\'s hull. It determines the ship\'s immersion in the water. 6. Displacement (DWT or Displ.): The displacement is the weight of the water displaced by the ship\'s hull when it is fully loaded with cargo, fuel, equipment, and personnel. It indicates the ship\'s carrying capacity and is usually measured in metric tonnes. 7. Block Coefficient (Cb): The block coefficient is a measure of the ship\'s form efficiency and is calculated as the ratio of the underwater volume of the ship\'s hull to the volume of a rectangular block with the same overall length, beam, and draught. 8. Prismatic Coefficient (Cp): The prismatic coefficient is a measure of the distribution of the underwater volume of the ship\'s hull and is calculated as the ratio of the underwater volume to the volume of a prism with the same length and cross-sectional area. 9. Midship Section Area (A): The midship section area is the cross-sectional area of the ship\'s hull at its widest point (amidships). It is used to determine the ship\'s buoyancy and resistance. 10. Block Ratio (λ): The block ratio is the ratio of the maximum cross-sectional area of the ship\'s hull to the area of a rectangle with the same length and beam. It is an indicator of the ship\'s hull form and resistance characteristics. Question 1: What is the purpose of the hull structure in a ship?

Question 7: Which type of ship hull design was commonly used in older vessels but has limitations in terms of safety? A) Single Hull B) Double Hull (Double Bottom) C) Double Hull (Double Sides) D) Triple Hull Answer: A) Single Hull Analysis: Single hull design, which consists of a single continuous shell, was prevalent in older ship designs. However, it has limitations in terms of safety, especially in the event of a collision or grounding, as it is more susceptible to hull breaches and water ingress. Question 8: What is the main propulsion system of the ship, located at the stern, responsible for providing forward or backward thrust? A) Bow thruster B) Rudder C) Stern thruster D) Propeller Answer: D) Propeller Analysis: The propeller is the main propulsion system of the ship, located at the stern. It is responsible for providing the necessary thrust to propel the ship forward or backward. Question 9: Which part of the ship\'s hull is responsible for deflecting waves and reducing the impact of water on the bow? A) Bulbous bow B) Transom stern C) Counter stern D) Stem Answer: D) Stem Analysis: The stem is the vertical component at the very front of the ship\'s bow. It helps deflect waves and reduces the impact of water on the bow, contributing to the ship\'s overall performance and safety. Top of Form Rudder: The rudder is a vertical, flat, or slightly curved surface located at the aft (rear) part of the ship, below the waterline. It is attached to the ship\'s hull through a rudder stock, which allows it to pivot horizontally. The rudder is used primarily for steering the ship and controlling its direction. When the rudder is turned, it redirects the flow of water passing over it, creating a force that turns the ship in the desired direction. Key points about rudders include: - Rudders are controlled by the ship\'s bridge or navigation control center through mechanical, hydraulic, or electronic systems. - The size and shape of the rudder depend on the ship\'s design, size, and intended purpose. - Modern ships often have double-acting rudders that improve steering efficiency by generating forces in both port (left) and starboard (right) directions. - Some vessels, particularly large ships, may have twin or multiple rudders to enhance maneuverability and control. Propellers: The propeller is the primary propulsion system of the ship, responsible for generating forward thrust to move the vessel through the water. It consists of multiple blades, typically made of metal, attached to a hub, which is connected to the ship\'s propulsion machinery (such as diesel engines or electric motors). When the propulsion machinery is activated, it drives the propeller, which rotates, creating a pressure difference in the water around it. This pressure difference results in a forward force that propels the ship. Key points about propellers include: - Propellers come in various designs, such as fixed-pitch, controllable-pitch, and azimuthing propellers, each offering specific advantages in terms of efficiency and maneuverability. - The size and number of blades on the propeller depend on the ship\'s design, engine power, and operating conditions. - In recent years, there has been a shift towards more efficient and environmentally friendly propeller designs to reduce fuel consumption and emissions. Together, rudders and propellers enable precise control of the ship\'s movement, allowing it to navigate safely in harbors, canals, and open waters. The proper coordination between the rudder and propeller is essential for effective steering and propulsion, especially during complex maneuvers and docking operations. Ship designers carefully consider the design and placement of both rudders and propellers to optimize the vessel\'s overall performance and maneuverability. Top of Form FITTINGS 1.

Safety fittings Load lines and draft marks are markings on a ship\'s hull that provide important information about the vessel\'s load-carrying capacity, safety, and stability. These markings are required by international regulations and are used by authorities to ensure that ships are operated safely and within their safe loading limits. Let\'s explore each of them in detail: Load Lines: Load lines, also known as Plimsoll lines, are a set of markings located on the ship\'s hull that indicate the maximum allowable draft based on the ship\'s design and construction. Draft refers to the vertical distance between the waterline and the deepest part of the ship\'s hull (keel). Load lines are used to ensure that the ship is not overloaded, as excessive loading can compromise the vessel\'s stability and safety. Load lines are marked on both sides of the ship\'s hull and consist of a series of horizontal lines and letters representing different load conditions and seasonal variations. The most common load line markings include: 1. TF (Tropical Freshwater): Represents the maximum permissible draft when the ship is sailing in tropical freshwater conditions. 2. F (Freshwater): Indicates the maximum allowable draft in freshwater regions outside the tropics. 3. T (Tropical Seawater): Indicates the maximum permissible draft in tropical seawater conditions. 4. S (Summer): Represents the maximum allowable draft during the summer season in non-tropical regions. 5. W (Winter): Indicates the maximum permissible draft during the winter season in non-tropical regions. Load lines are determined based on the ship\'s stability and buoyancy characteristics, and they vary depending on the ship\'s size, type, and construction. Compliance with load line requirements is essential to ensure the ship\'s safety and seaworthiness. Draft Marks: Draft marks are numerical markings painted on the ship\'s hull at specific intervals, usually near the bow and stern, and on both sides of the vessel. These marks indicate the ship\'s actual draft at a given moment. Draft marks are used to measure the ship\'s displacement and loading condition, enabling the crew to monitor the ship\'s stability and adherence to load line requirements. The numerical values on draft marks are usually given in meters or feet, and they help the crew and port authorities ensure that the ship is not overloaded and that it is floating at the appropriate draft level according to the load line requirements for its current operating condition. In summary, load lines and draft marks are essential markings on a ship\'s hull that provide vital information about the vessel\'s loading capacity and stability. By adhering to load line regulations and monitoring draft marks, ship operators can ensure the safe and efficient operation of the vessel. Top of Form 1. Freeboard: Freeboard is the vertical distance between the waterline and the uppermost continuous deck of the ship. It is a safety consideration and ensures that the ship has sufficient reserve buoyancy and remains afloat even when exposed to waves and adverse weather conditions. 2. Draught: Draught (also spelled \"draft\") is the vertical distance between the waterline and the deepest point of the ship\'s hull. It indicates the immersion of the ship in the water. The ship\'s draught varies depending on its loading condition, i.e., the amount of cargo, fuel, ballast, and other equipment on board. 3. Depth: Depth is the vertical distance between the ship\'s uppermost continuous deck and the keel. It represents the overall height of the ship\'s hull. 4. Molded Depth: Molded depth is the vertical distance between the base line (the reference plane from which all other heights and depths are measured) and the uppermost continuous deck at the side of the hull. Molded depth is used for design and construction purposes. What is G. A. Plan ?

The solid floor provides a continuous, solid surface on the interior of the hull, ensuring a stable and secure platform inside the ship. Girders are structural beams that support the ship\'s superstructure, providing strength and stability to the vessel. Deck plating serves as a flat, walkable surface on the deck, allowing crew members to move and work safely. Outer plating refers to the plates forming the outer skin of the ship\'s hull, protecting it from corrosion and environmental elements. Deck beams are horizontal beams that support the ship\'s deck, providing a flat surface for cargo storage and evenly distributing loads across the hull.

Explanation: Bulkheads are partitions that create watertight compartments in a ship to prevent water from flooding and help maintain the vessel\'s structural integrity. Solid floors provide a continuous, solid surface inside the hull for stability and practical purposes. Girders are horizontal beams that support the ship\'s superstructure and distribute loads across the ship\'s framework. Deck plating provides a flat and safe surface for crew members to move and work on the deck. Outer plating protects the ship\'s hull from corrosion and environmental elements like water and air exposure. Deck beams are horizontal beams that support the ship\'s deck and help in distributing the weight of cargo evenly across the ship.

Explanation: The primary function of a longitudinal frame is to distribute loads and stresses along the length of the ship, ensuring structural integrity and strength. Longitudinal frames are oriented parallel to the keel, running along the length of the ship\'s hull. Longitudinal frames and transverse frames work together to provide comprehensive structural support: longitudinal frames run parallel to the keel, while transverse frames run perpendicular to the keel. The placement of longitudinal frames along the hull is crucial as it helps in ensuring an even distribution of weight and stress, contributing to the ship\'s overall stability.

It is difficult to follow and lacks clear divisions **Deck Department**\ \ [Chief Officer]: The Chief Officer, also called Chief Mate or First Mate, is the head of the deck department. He is second-in-command after the ship\'s master. The Chief Officer\'s primary responsibilities are the vessel\'s cargo operations, stability, and supervising the deck crew. The Chief Officer is responsible for the safety and security of the ship, as well as the welfare of the crew on board.\ \ The Chief Officer typically stands the 4-8 hours of a navigation watch. Additional duties include ensuring good maintenance of the ship\'s hull, cargo gears, accommodations, the lifesaving and firefighting appliances. The Chief Officer also trains the crew and cadets on various aspects like safety, firefighting, search and rescue and various other contingencies.\ \ [Second Officer]: The Second Officer, also called Second Mate, is usually in charge of ship navigation with a position below Chief Officer and above Third Officer. He/she is the third-in-command, after the Master and Chief Officer. The second officer typically stands to watch from 1200 to 1600 at noon and again from 0000 to 0400 in the nights.\ \ [Third Officer]: The third officer also called 3rd Mate primarily charged with the safety of the ship and crew. The Third officer generally serves as the ship\'s chief safety officer. The Third Officer is the next licensed position on board the vessel, as fourth-in-command. **Engine department**\ \ The engineers on board ships are also called technical officers. They are responsible for keeping the machinery maintained and operational. Today, ships are complex systems that combine a lot of technology within a small space. This includes not only the engines and the propulsion system but also, for example, the electrical power supply, devices for loading and discharging, garbage incineration, and freshwater generators. Additionally, more and more environmental protection technologies, fuel treatment systems, and cargo conditioning devices are used onboard ships. The upkeep of all these are in the hands of engine department staff.\ \ [Chief Engineer:] The Chief Engineer on a commercial vessel is the official title of someone qualified to manage and oversee the engine department. The qualification for this position is colloquially called a \"chief\'s ticket.\" The Chief Engineer is responsible for all operations and maintenance of all engineering equipment throughout the ship.\ \ [Second Engineer]: The Second Engineer is the officer responsible for supervising the daily maintenance and operation of the engineering systems. He or she reports directly to the Chief Engineer. The Second Engineer is second in command in the engine department after the ship\'s Chief Engineer. The person holding this position is typically the busiest engineer onboard the ship, due to the supervisory role this engineer plays and the operations duties performed. Operational duties include responsibility for the refrigeration systems, main engines, and any other equipment not assigned to the third or fourth engineers.\ \ The Third Engineer is junior to the second engineer in the engine department and is usually in charge of boilers, fuel, auxiliary engines, condensate, and feed systems. This engineer is typically in charge of bunkering if the officer holds a valid certificate for fuel transfer operations.\ \ Fourth Engineer: The Fourth Engineer is junior to the third engineer in the engine department. The most junior marine engineer of the ship is usually responsible for electrical, sewage treatment, lube oil, bilge, and oily water separation systems. Depending on usage, this person usually stands a watch. Moreover, the fourth engineer may assist the third officer in maintaining the lifeboats\' proper operation.\ \ **Steward\'s department**\ \ Chief Steward: The Chief Steward directs and assigns personnel that does functions such as preparing meals, cleaning and maintaining officers\' quarters, and managing the stores. The Chief Steward also does other activities such as overtime and cost control records and may require or purchase stores and equipment. Other additional duties may include taking part in cooking activities. The Chief Steward is assisted by a chief cook and his/her assistant cooks, mess men and assistant stewards. 1. **What is "Camber" in the context of ship construction?** - a\) The overall width of the ship at its widest point - b\) The angle at which the ship's hull plate departs from the vertical - c\) The slight upward curvature given to a ship's decks or to a horizontal surface - d\) The vertical distance from the keel to the waterline - **Answer:** c) The slight upward curvature given to a ship's decks or to a horizontal surface 2. **What is the primary purpose of camber in ship decks?** - a\) To increase the ship's speed - b\) To facilitate effective drainage - c\) To improve the ship's aesthetics - d\) To reduce the ship's weight - **Answer:** b) To facilitate effective drainage 3. **What is "Rise of Floor" or "Deadrise"?** - a\) The rise of the bottom shell plating line above the base line - b\) The curvature of the deck in the longitudinal direction - c\) The inward slope of a ship's hull at the upper part of the sides - d\) The outward curvature of the ship's hull above the waterline - **Answer:** a) The rise of the bottom shell plating line above the base line 4. **What does "Tumblehome" refer to in naval architecture?** - a\) The outward curvature of the ship's hull above the waterline - b\) The inward slope or curvature of a ship's hull at the upper part of the sides - c\) The curvature of the deck in the longitudinal direction - d\) The straight part at the center of the ship where the water lines and buttocks have no curvature - **Answer:** b) The inward slope or curvature of a ship's hull at the upper part of the sides 5. **What is the function of "Flare" in ship design?** - a\) To increase the ship's speed - b\) To improve the ship's aesthetics - c\) To increase buoyancy and stability - d\) To reduce the ship's weight - **Answer:** c) To increase buoyancy and stability 6. **What is "Sheer" in the context of ship construction?** - a\) The curvature of the deck in the longitudinal direction - b\) The rise of the bottom shell plating line above the base line - c\) The inward slope or curvature of a ship's hull at the upper part of the sides - d\) The outward curvature of the ship's hull above the waterline - **Answer:** a) The curvature of the deck in the longitudinal direction 7. **What is the "Parallel Middle Body" of a ship?** - a\) The straight part at the center of the ship where the water lines and buttocks have no curvature - b\) The widest part of the ship - c\) The total length of the ship from one end to the other - d\) The vertical distance from the top of the keel to the top of the upper deck beams - **Answer:** a) The straight part at the center of the ship where the water lines and buttocks have no curvature 8. **What does "Length Over All (L.O.A.)" refer to?** - a\) The distance from the forward perpendicular to the after perpendicular - b\) The total length of the ship from one end to the other, including bow and stern overhangs - c\) The vertical distance from the top of the keel to the top of the upper deck beams - d\) The height of the ship at the midship section from the base line to the moulded line of the deck at side - **Answer:** b) The total length of the ship from one end to the other, including bow and stern overhangs 9. **What is "Molded Depth"?** - a\) The height of the ship at the midship section from the base line to the moulded line of the deck at side - b\) The vertical distance from the top of the keel to the top of the upper deck beams amidships at the gunwale - c\) The height from the base line to the load water line - d\) The difference between the moulded depth and the moulded draft - **Answer:** b) The vertical distance from the top of the keel to the top of the upper deck beams amidships at the gunwale 10. **What is "Freeboard (Moulded)"?** - a\) The height from the base line to the load water line - b\) The difference between the moulded depth and the moulded draft - c\) The vertical distance from the top of the keel to the top of the upper deck beams amidships at the gunwale - d\) The curvature of the deck in the longitudinal direction - **Answer:** b) The difference between the moulded depth and the moulded draft Feel free to adjust or add more questions as needed!
