DNV Classification Society Certification

Yuantai Derun Steel Pipe Manufacturing Group has finally obtained the inspection certificate of ship steel pipes in various regions of the world after layers of inspection. Welcome to order and consult.

history
Det Norske Veritas Management Services Group was established in 1864. [1]
DNV ITGS, a global leader in process improvement, is a combination of four leading consulting companies in various fields in Europe.
Globally, DNV ITGS has more than 200 process improvement experts, more than 20 SEI authorized chief assessors and lecturers, implemented more than 100 official evaluations and 300 unofficial evaluations, and has more than 100 leading customers in various industries, ranking first in the European CMMI service field.
In China, DNV came to China in 1888 and has nearly 40 offices and more than 600 employees in China. DNV ITGS Asia officially launched consulting services related to process improvement in 2006.
service
Under the purpose of "protecting life, property and environment", DNV provides customers with comprehensive risk management and various assessment and certification services, mainly involving classification services, certification services, technical services, etc. DNV has set up 300 branches in 100 countries around the world, with about 16500 employees. DNV is based on scientific and technological knowledge and experience. Its main purpose is to protect life and property, and also to protect the natural environment. DNV does its best to manage risks for customers. Offices around the world create a flexible and efficient service network for the organization. Offices have been set up in Chinese Mainland, Hong Kong and Taiwan, China, China. There are 285 employees in Greater China, including professional surveyors, engineers and auditors, who provide various services for different industries, including ship classification and certification, product and management system verification, and scientific and technological services.
advantage
DNV's certification business always adheres to the advantage of leading technology, and has obtained credit recognition from more than 80 countries in the world. It has issued 65000 management system certificates worldwide. As the first international certification authority to enter the Greater China region, DNV Det Norske Veritas has so far established 13 offices in the Greater China region and issued nearly 5000 certificates.
merge
DNV and GL announced their official merger. The contract was signed on December 20, 2012, and the new company was renamed DNV GL Group.
According to the shipping website, DNV holds 63.5% shares and GL holds 36.5% shares after the merger. The new DNV-GL Group headquarters will be located in Oslo, Norway, but the ship classification service headquarters will be located in Hamburg, Germany. DNV and GL will continue to operate independently, which will guide a new round of development in the maritime industry.
According to the calculation of deadweight tonnage of classified ships, DNV and GL Noble Denton are 216 million DWT and 137 million DWT respectively, ranking fourth and fifth respectively in the total tonnage of ships registered by classification societies. After the merger, the total deadweight tonnage of the ships classified by both parties will reach 354 million DWT, which will exceed the total registered tonnage of Japan Classification Society (NK) (321 million DWT) and become the first classification society in terms of registered deadweight tonnage. The total number of registered ships will exceed 12000, which is more than the total number of registered ships of French Classification Society (11000).
The combination of DNV and GL not only strengthens its economic strength, but also strengthens its influence. DNV said that since the Nobel Peace Prize event in 2010, its business with China has been affected to some extent. According to the Norwegian Evening Post, Norway's exports to Asia increased last year, but its exports to China decreased by 9% (excluding oil and gas), from 15.3 billion kronor in 2011 to 13.9 billion kronor. If we take into account the exchange rate change between the krona and the RMB, Norway's exports to China fell by 15% last year. The Norwegian Sea Products Committee said that Norwegian salmon used to occupy 90% of the Chinese market, but now it has dropped to 50%. Under such circumstances, DNV's strategic choice is to improve its strength and occupy the market, especially the Chinese market, with the help of GL, which has made a good statement, and its original position and strength.

As a knowledgeable steel manager, I understand the importance of selecting the right shipbuilding steel tubing to ensure the durability and longevity of your vessel. Shipbuilding plates are an important part of the marine industry and choosing the correct grade is integral to the structural integrity of a ship. Important shipbuilding steel grades include LR AH36 and ASTM EH36, which offer high-impact strength and excellent weldability.

The quality and price of shipbuilding steel is a key factor to consider before sourcing. prices for AH36 steel can vary from supplier to supplier and it is important to ensure that costs are matched to the quality of the steel. Shipbuilding steel prices can also fluctuate depending on market conditions, so it is important to monitor the market and make intelligent purchases.

Factors such as the intended use of the vessel, the sailing environment and the loads to be carried must be taken into account when selecting the right steel for shipbuilding. For example, the ASTM EH36 steel plate is ideally suited for use in harsh marine environments and has excellent seawater corrosion resistance.

In short, shipbuilding steel tubes are an integral part of ship construction in the offshore industry. The appropriate choice of shipbuilding plate and grade will ensure the durability of the vessel and provide a long service life. It is important to be aware of shipbuilding steel prices, AH36 steel prices, and other factors that may influence the purchasing decision. Overall, it is important to always choose from reputable suppliers and sources that offer reliable shipbuilding steel grades.
