This is a model of Hua San, a crude oil tanker. She was built in China by the Shanghai Waigaoqiao Shipyard in 2008. Tankers like this are the largest man-made moving objects on earth. Her launch marked a new era of tanker construction.

Every day, thirty-eight million tons of crude oil sets off by sea. The safety of the sailors who transport it, the environment in which they work and the cargo itself, is assured by marine classification societies who oversee the construction of ships like Hua San.

Hua San’s launch in 2008 set new standards for safe tanker construction.
She was the first tanker built to CSR notation. CSR stands for ‘Common Structural Rules’. which were developed by the International Association of Classification Societies to create safer and more dependable ships and was adopted for all new ships contracted after April 2006.

The Common Structural Rules were adopted to remove variations in design and achieve consistency in construction quality – by establishing the minimum requirements to mitigate the risks of major hull structural failure.
They featured increased strength requirements and more robust fatigue-related construction, based on a target of a vessel life of 25 years, measured under harsh North Atlantic operational conditions.

This was an important time to introduce new rules: global economies were gripped by recession from 2006. In such challenging economic times, it was essential to cast a spotlight on the marine industry and guarantee the quality of construction.

Oil tankers are classified based on their carrying capacity in deadweight tons, which is the total weight of the ship including cargo, crew, and stores minus the weight of the ship if it were empty.

With a capacity of 318,000 dwt tons Hua San is one of the largest vessels that can be classed as ‘VLCC’ – which stands for Very Large Crude Carrier.
First developed in the 1960s, VLCCs have a capacity that ranges from 200,000 deadweight tons to 320,000 and can carry two million barrels of oil.

Hua San is not only the first VLCC built to Common Structural Rules, but also the biggest vessel by deadweight ever built in China.
