Main Applications of CCS Grade E Shipbuilding Steel Plates in Offshore Engineering

1. Deep-sea and polar merchant vessels

Suitable for the outer hull plating, bottom plating and load-bearing deck structures of bulk carriers, container ships and oil tankers operating in cold waters at high latitudes. This steel plate exhibits excellent impact resistance at temperatures as low as -40°C, effectively preventing brittle fracture of the steel caused by low seawater temperatures and impacts from ice.

2. Offshore Platform Structures

Suitable for auxiliary support structures, living module floor plates and seawater pipeline supports on offshore drilling platforms. CCS Grade E steel offers excellent resistance to seawater corrosion and low-temperature wind and wave impacts, helping to extend the service life of offshore platforms.

3. Specialised Engineering Vessels

Suitable for specialised vessels such as icebreakers, rescue vessels and oceanographic survey vessels. These vessels operate in extremely cold environments and are subjected to complex stress conditions, requiring the steel plates to maintain excellent mechanical stability under alternating loads and in low-temperature environments.

4. Key Auxiliary Components of Vessels

Includes components such as hatch coamings, longitudinal beams and bulkhead stiffeners on large vessels. CCS Grade E steel effectively distributes structural stresses, reducing fatigue damage during long-term voyages.

Note:

CCS Grade E steel is not suitable for high-strength bearing components in ultra-large vessels where high load-bearing capacity is required. For heavy-duty structures, it is recommended to use high-strength marine steels such as EH36 to meet the corresponding load-bearing requirements.
