Benefits of Shipbuilding Steel Plate

 

product-401-353Strength and durability
Shipbuilding steel plates are specifically designed to withstand the harsh conditions at sea. They are made with a high-strength material that can withstand the impact, pressure, and vibrations encountered during the ship's operation. This ensures the structural integrity of the vessel, making it safe and capable of withstanding rough weather and heavy loads.

 

Corrosion resistance
Shipbuilding steel plates are treated with various coatings and anti-corrosion materials to protect them from the corrosive effects of seawater, salt, and atmospheric conditions. This significantly extends the lifespan of the ship, reducing maintenance and repair costs.

 

Weldability
Shipbuilding steel plates have excellent weldability, allowing for efficient and strong joints. This enables shipbuilders to construct complex structures and secure different parts of the ship together without compromising its strength.

 

Lightweight
Shipbuilding steel plates are designed to be both strong and lightweight. This is crucial for ships as it helps improve their fuel efficiency and overall performance. The reduced weight allows ships to carry larger cargo loads, increasing their profitability.

Process of Shipbuilding Steel Plate

 

01.

Material selection

The first step in shipbuilding steel plate is to select the appropriate material. The material should have high strength, good corrosion resistance, and the ability to withstand harsh marine environments.

 
 

02.

Cutting and shaping

Once the material is selected, the shipbuilding steel plate is cut into the desired shape and size. This is often done using automated cutting machines, such as plasma or laser cutting, to ensure precision and accuracy.

 
 

03.

Rolling and forming

After cutting, the shipbuilding steel plate is rolled and formed into the desired shape, such as flat sheets or curved plates. This is achieved through hot or cold rolling processes, which involve passing the plate through a series of rollers to achieve the desired thickness and shape.

 
 

04.

Welding and joining

 

Shipbuilding steel plates are often joined together through welding. The plates are aligned and welded together using various welding techniques, such as arc welding or gas welding, to create a strong and durable structure.

 
 

05.

Surface treatment

Once the welding is complete, the shipbuilding steel plates undergo surface treatment to improve their corrosion resistance and appearance. This may involve cleaning, degreasing, and applying protective coatings, such as paint or zinc coating, to prevent corrosion and maintain the integrity of the plates.

 
 

06.

Quality control

 

Throughout the process, strict quality control measures are implemented to ensure that the shipbuilding steel plates meet the required standards and specifications. This includes regular inspections, testing, and documentation of the materials and processes used.

 
 

07.

Inspection and certification

Once the shipbuilding steel plates are manufactured, they undergo rigorous inspection and certification processes to ensure their compliance with industry standards and regulations. This is done by authorized bodies, such as classification societies, who verify the quality and safety of the plates.

 
 

08.

Delivery and installation

Finally, the shipbuilding steel plates are ready for delivery and installation. They are transported to the shipyard or construction site, where they are installed and integrated into the ship's structure. This involves careful planning and coordination to ensure the plates are positioned correctly and securely.

Case : Steel Plates Supply for 100,000m³ Full Containment Ammonia Storage Tank Project

 

GNEE STEEL is currently participating in the procurement phase of a 100,000m³ full containment ammonia storage tank project, supplying high-quality steel plates for critical tank components. Due to the corrosive nature of ammonia and the risk of Ammonia Stress Corrosion Cracking (SCC), the project requires strict metallurgical control of materials according to EN 10028-3 standards.

 

One of the most important technical requirements of this project is the strict limitation of the actual Yield Strength (Re) for all NL2 grade materials. To prevent SCC risks in ammonia storage environments, the actual yield strength must not exceed 390 MPa, regardless of the nominal values specified in the standard or plate thickness ranges. This requirement places higher demands on steelmaking process control, heat treatment stability, and material testing.

Project Materials and Technical Requirements

 

The project mainly uses P355NL2 and P275NL2 normalized pressure vessel steel plates, which are widely applied in low-temperature storage tanks due to their excellent toughness and weldability.

 

Key technical specifications include:

  • Material grades: P355NL2 and P275NL2 (Normalized)
  • Yield strength: Standard minimum / Maximum limited to 390 MPa
  • Hardness: ≤ 225 HBW in base material
  • Impact testing: Charpy-V notch test at -50°C, minimum 27J
  • Certification: EN 10204 3.1 certificate, with optional 3.2 certification

 

These strict requirements ensure that the steel plates maintain stable mechanical properties and high resistance to ammonia-induced stress corrosion during long-term operation.

Project Plate Quantities and Thickness Distribution

 

The total steel demand for this ammonia storage tank project is several thousand tons, mainly distributed across different tank sections:

 

P355NL2 – Inner & Outer Tank Shell Plates

  • Lower shell courses: 50 mm thickness – approx. 2,000 tons
  • Middle shell courses: 25 mm thickness – approx. 1,400 tons
  • Upper shell courses: 10 mm thickness – approx. 500 tons

 

P275NL2 – Tank Bottom Plates

  • Thickness: 10–15 mm – approx. 750 tons

 

P275NL2 – Suspended Roof Structure

  • Thickness: 5–8 mm – approx. 180 tons

 

S275JR – Outer Roof (Ambient Structure)

  • Thickness: 10 mm – approx. 450 tons

 

To improve tank fabrication efficiency and reduce circumferential welds, the project also requires wide steel plates to minimize welding joints, which helps reduce the potential risk of SCC in ammonia service conditions.
