China's first vessel capable of conducting rescue in deep, open water was delivered and put into service on Wednesday in the South China Sea.

The ship, Nanhaijiu 102, is the most advanced rescue vessel in the area and will play a role in emergencies, said the Ministry of Transport.

The all-weather, high-powered rescue ship designed and built by China, is 127 meters long and 16 meters wide, with displacement of 7,300 tonnes and range of 16,000 nautical miles.

Carrying a towing system and autonomous underwater vehicle that can dive as deep as 6,000 meters, the ship is the country's first rescue ship that can conduct air, sea and underwater searches at the same time.

The ministry said Nanhaijiu 102, which can rescue 200 people at a time, is designed for bad sea conditions including 12th grade waves and is suitable for the refueling and landing of helicopters.

China has 74 special rescue ships, among which 31 are in southern sea areas. In addition, the country has 20 rescue helicopters, according to the ministry.
