Internal Structural Elements of Ships are the entirety of critical components that ensure a vessel not only remains afloat but also maintains its structural integrity under the most demanding ocean conditions. In the modern shipbuilding industry, the design and production of these elements require millimetric precision and advanced engineering knowledge. Asem Process, with its deep experience in the maritime and industrial manufacturing sectors, plays a pioneering role in the production of complex systems and components needed within the internal structure of ships. In the world of marine engineering, the internal structure can be thought of as the skeleton of a building; however, this skeleton must also be resistant to dynamic loads, corrosion, and high pressure.
Target Queries and Frequently Asked Questions
In this article, you will find answers to the following questions most frequently asked in the sector:
- What are the internal structural elements of a ship?
- Which are the fundamental parts used in shipbuilding?
- What are the functions of beams, frames, and girders?
- What services does Asem Process offer in the maritime sector?
- Which elements ensure the strength of a ship?
The Importance of Structural Design in Shipbuilding
Marine vessels, unlike structures on land, rest on a mass that is constantly in motion. Wave loads, cargo weight, machinery vibrations, and the buoyancy of water create immense stress on the ship’s hull. The fundamental element that withstands this stress is the set of internal structural elements of the ship. Asem Process, aware of these structural requirements, is a solution partner specializing particularly in pressure vessels, cryogenic systems, and shipboard piping systems.
Basic Systems Forming the Ship Structure
When examining the internal structure of a ship, two main systems are generally mentioned: the transverse system and the longitudinal system. The internal structural elements used in both systems increase the ship’s resistance to bending and torsional moments. High-quality steel plates and profile elements used in Asem Process manufacturing processes guarantee the longevity of these systems.
Internal Structural Elements of Ships
Every part of the structure, referred to as the “skeleton” in shipbuilding, has a specific name and function. Here are the parts that form the heart of the ship:
1. Frames (Postalar)
Known as the ribs of the ship, frames ensure that the hull maintains its form in the transverse direction. They support the outer plating and withstand the hydrostatic pressure applied by the water. They are the most common among internal structural elements. Asem Process minimizes structural weaknesses with the precision welding technologies used in the assembly of frames.
2. Beams (Kemereler)
These are horizontal elements that carry the decks and connect the frames to each other. They contribute to the transverse strength of the ship. They transmit the weight of loads placed on the deck (containers, vehicles, or passengers) to the ship’s hull via the frames.
3. Beam Knees and Half Beams
These are short beams used where deck continuity is interrupted, such as hatch openings or stairwells. Since these points are where stress accumulation is highest among internal structural elements, they require the engineering touch of expert firms like Asem Process.
4. Longitudinals
These are elements that extend from the bow to the stern of the ship and prevent the ship from bending longitudinally. They are vital, especially in large tonnage ships, to prevent the ship from “breaking its back” (sagging/hogging) while on a wave crest.
Asem Process and Its Role in the Maritime Sector
Asem Process is not just a manufacturer but a center that produces solutions for complex engineering problems. In the maritime sector, not only the main skeleton of the ships but also the process equipment placed inside this skeleton is of critical importance.
Cryogenic Tanks and Ship Fuel Systems
Due to environmental regulations today, ships are turning to fuels such as LNG (Liquefied Natural Gas). Asem Process steps in at this point, designing and producing cryogenic tanks and fuel supply systems integrated into the ship. These systems must work in full harmony with the internal structural elements.
Stainless Steel Piping and Skid Systems
There are thousands of meters of pipelines in the engine rooms of ships. Asem Process offers stainless piping solutions resistant to seawater and corrosion. Additionally, it significantly shortens shipbuilding time by producing skid units that can be placed on the ship with a plug-and-play logic.
The Importance of Plate Processing in Ship Strength
The durability of a ship depends as much on the quality of the material used as on how that material is processed. Plasma cutting, bending, and certified welding processes carried out within Asem Process meet the high tolerances required for internal structural elements.
Other Critical Parts in the Internal Structure of Ships
Frames and beams alone are not enough to keep the ship standing. Other auxiliary elements are also part of the system:
Bulkheads (Perdeler)
These are walls that divide the ship vertically into sections. They provide both structural support and prevent the ship from sinking by stopping water from passing to other compartments in case of flooding (damaged stability). They rank at the top in terms of safety among internal structural elements.
Girders (Tübe)
These are heavy structural elements extending in the longitudinal direction. They are usually found in the ship’s bottom (double bottom) and, together with the ship’s keel, form the main load-bearing strength. Asem Process manufactures in accordance with industrial standards for these heavy industrial components.
Floors (Döşekler)
These are vertical plates located at the bottom of the ship, beneath the frames, forming the double bottom structure. They form the inner parts of the tanks and maximize the strength of the ship at the bottom.
Asem Process Industrial Solutions and Application Areas
Asem Process also operates in heavy industrial branches outside of maritime; however, maritime is the field where the company most displays its precision manufacturing capabilities. Heat exchangers, compressed air tanks, and separators used in ships are products included in the company’s product range and integrated among internal structural elements.
Innovation in Marine Engineering
As shipbuilding technology develops, lighter but more durable structures are targeted. Asem Process contributes to this goal through R&D studies. Expertise in processing aluminum and alloy steels provides a critical advantage in the construction of modern and fast ships.
Maintenance and Repair of Internal Structural Elements
Over time, the corrosive effect of seawater and constant mechanical stress cause metal fatigue and corrosion on internal structural elements. To prevent this, regular surveys and maintenance are essential. Asem Process works in coordination with ship repair and maintenance yards to ensure the exact replacement and reinforcement of damaged internal structural parts.
Structural Reinforcement Applications
During the modernization (retrofit) phase of old ships, new systems (e.g., BWTS – Ballast Water Treatment Systems) must be installed on existing internal structural elements. Asem Process ensures that these new systems are integrated in line with static calculations without damaging the ship’s existing structure.
Quality Control and Standards in Shipbuilding
The margin for error in maritime is zero. Therefore, every internal structural element produced must comply with the standards set by international classification societies (Lloyd’s, ABS, BV, etc.). Asem Process keeps product safety at the highest level by using non-destructive testing (NDT) methods (Radiography, Ultrasonic, Magnetic Particle, etc.) at every stage of the manufacturing process.
Conclusion and Future Vision
Internal Structural Elements of Ships are the invisible heroes of a vessel. Ships, which appear only as a massive metal mass from the outside, actually house a tremendous engineering marvel consisting of thousands of parts inside. Asem Process is present in every cell of this complex structure with its high-quality manufacturing and reliable engineering solutions. For safe ships that will withstand the harsh conditions of the seas, every bolt, every weld, and every plate in the internal structure is of great importance. In the maritime technologies of the future, we will continue to hear the name Asem Process with more efficient, more environmentally friendly, and more durable projects.
