What are the key features of offshore steel plates?
Offshore steel plate solutions are engineered to offer specific properties. These ensure ongoing safety and structural integrity in marine environments. Their key features include:
Strength and durability
Offshore structures are constructed to withstand constant pressures from volatile weather conditions and strong ocean currents. Offshore steel plates offer the strength and durability needed to maintain the structural integrity of these structures.
Corrosion resistance and longevity
Offshore steel plates are coated and treated using specially selected agents to give them corrosion-resistant properties. These properties help to maximise the lifespans of offshore structures and limit the need for frequent maintenance, repairs, and replacements.
High yield and tensile strength
Another key feature of offshore steel plates is their high yield and tensile strength. This strength enables the plates to withstand major stress without the risk of structural damage or deformation.
Compliance and standards
Offshore steel plates are manufactured according to strict compliance standards. This ensures consistent quality and optimal safety outcomes. Plates manufactured in the UK must comply with standards like EN 10225 and ASTM A131.
EN 10225 defines the technical manufacturing and delivery conditions for offshore structural steels. The standard specifically governs how weldable steels like offshore steel plates should perform under a range of use conditions. ASTM A131 regulates the quality of steel plates manufactured for moderate and low temperature-servicing pressure vessels.
All offshore steel plate product lines must comply with numerous safety regulations and environmental standards. These standards reduce the impacts of steel plates on sensitive marine ecosystems and promote ongoing protection for employees working on offshore structures.
What are the applications of offshore steel plates?
The offshore steel plate market serves a wide range of industries and organisations. Offshore steel plates are broadly used in construction applications such as:
- Underwater pipelines: Offshore steel plates are used to build oil and gas pipelines that channel these resources from underwater reserves.
- Oil and gas platforms: Oil and gas platforms are crafted from durable, corrosion-resistant steel plates.
- Offshore support structures: Steel plates are used to stabilise and support offshore structures to ensure their strength and structural integrity.
- Ship construction: Offshore steel plates are a vital component of many parts of ships, including their decks and hulls.
- Marine-based wind farms: Wind turbines are constructed using steel plates to reinforce their foundations. This also provides them with sufficient strength to withstand demanding offshore conditions.
What are the different grades of offshore steel plates?
The steel grade for offshore steel plates varies. Each grade provides specific properties that align it with certain applications. The various grades of offshore steel plates include:
- Thermo-mechanically controlled processed steels (TMCP steels): These plates offer enhanced durability and are well suited to welding.
- Ship-building steels: Designed for ship construction, these steels come in plate, bulb flats, angles, and inverted angles flats forms in ship building grades LRS/ABS/DNV/GL.
- Corrosion-resistant steels: Plates crafted from corrosion-resistant steel are engineered to withstand the many challenges of harsh marine environments, including corrosive salt exposure.
- Abrasion-resistant plates: Our abrasion-resistant plates offer a guaranteed Brinell hardness of at least 320 BHN.
- High-strength low alloy steels (HSLA steels): This steel grade for offshore steel plates is prized for its favourable strength-to-weight ratio.
