Emphasis on Standard - setting

 

ABS (American Bureau of Shipping)

 

When formulating steel plate standards, ABS pays high attention to the comprehensive performance of ships in the global trade and transportation environment. As American maritime trade involves a wide variety of cargo types and complex shipping routes, including the transportation of high - value cargo and long - distance trans - ocean voyages, its certified steel plate standards focus more on the safety of ships under long - term, heavy - load, and various complex sea conditions. For example, in the high - risk situation of oil tankers transporting a large amount of crude oil, ABS - certified steel plates have more stringent requirements for anti - corrosion and anti - fatigue performance to prevent serious consequences such as environmental pollution caused by crude oil leakage.

 

From the perspective of technological updates, ABS closely integrates with the advanced materials science research achievements in the United States. The United States invests a huge amount in the field of materials research and development, and ABS will promptly incorporate new materials testing methods and quality - control technologies into the steel plate certification standards. For example, in the research and application of high - strength and high - toughness steel, ABS will be the first to consider using it in the certification standards for key structural components of ships.

 

Differences in Application - Field Preferences

 

ABS

 

In the field of offshore - engineering equipment, especially for large - scale and complex structures such as deep - sea drilling platforms and floating production storage and offloading (FPSO) vessels, ABS - certified steel plates are widely used. This is because the United States is in a leading position in the field of deep - sea energy development, and its certified steel plates can meet the high requirements of the harsh deep - sea environment. For example, deep - sea drilling platforms need to withstand huge wave - impact forces, seawater pressure, and complex dynamic loads, and ABS - certified steel plates can provide reliable guarantees in terms of strength, toughness, and anti - fatigue performance.

 

In high - end ship - building, such as large - scale luxury cruise ships and high - speed passenger ships, ABS - certified steel plates also have certain advantages. For luxury cruise ships, there are numerous internal facilities, and the requirements for the stability and safety of the hull structure are extremely high. At the same time, the comfort and safety of passengers also need to be considered, and ABS - certified steel plates can meet these comprehensive requirements.

Other Classification Societies (Taking DNV and KR as Examples)

 

DNV (Det Norske Veritas)

 

DNV - certified steel plates perform well in polar ships and offshore wind - installation vessels. Norway is located in Northern Europe and pays more attention to polar shipping and offshore renewable - energy development. For polar ships, DNV - certified steel plates focus on low - temperature toughness and ice - resistance performance to ensure the safety of ships sailing in the polar ice - covered areas. For offshore wind - installation vessels, due to their special working environment and the need for frequent hoisting and installation of large - scale wind - power equipment, DNV - certified steel plates can meet the requirements in terms of structural strength and anti - fatigue performance.
