Taizhou, a key manufacturing city on the East China Sea, witnesses another historic breakthrough of China's marine research equipment.
On May 5, 2026, the Haiying Jiake — China's first 3,500-ton comprehensive ocean research vessel fully funded, built and operated by private investors — was launched smoothly in Wenling, Taizhou, Zhejiang Province.
The ship is 82 meters long and 18 meters wide, with a full load displacement of 3,500 tons. It adopts full electric propulsion and DP2 high-precision dynamic positioning system. Thirty-six fishermen jointly raised 150 million yuan to build it. This model fills the gap in China where private investors participate in building deep-sea research vessels.
This ship carries both the fishermen's passion for the ocean and national marine research missions. ERA marine PP-R pipes are used for the ship's cold and hot domestic water supply system to guarantee daily water for all crew members. The durability and stability of the piping system directly affect living conditions on board.
ERA marine PP-R pipes feature high strength, corrosion resistance and chlorine disinfection resistance. They can carry hot water at high temperatures for long-term use. Supported by a full set of fittings, they enable flexible cold and hot water circulation designs. The pipes keep steady hot water supply and stop bacterial growth. This reliable long-term piping solution cuts maintenance costs over the whole service life of the vessel.
Every step from fundraising to construction of Haiying Jiake was led by private companies. ERA marine PP-R pipes weigh only 1/9 of steel pipes, greatly reducing the overall weight of the ship's piping system.
ERA PP-R pipes use hot melt welding and require fewer extra connecting parts. They can be laid quickly in narrow spaces. ERA's technical team offered full support during installation to finish the piping system on schedule.
The ship will face rough sea conditions during ocean missions. ERA marine PP-R pipes have good impact resistance. Hot melt joints stay sealed under constant vibration, perfectly matching marine working environments.
ERA PP-R pipes can work under continuous hot water up to 95°C with little heat loss. For research teams staying at sea for dozens of days, steady hot water is essential for comfortable living.
Sailing across global waters with variable water quality, ERA PP-R pipes resist corrosion and scale buildup. They maintain smooth water flow and safe daily water supply for crew members.
After launching, Haiying Jiake will undergo two months of outfitting and equipment testing, and start sea trials in July 2026.
Once put into service, the vessel will help universities and research institutes carry out marine resource surveys, seabed mapping, marine biological sampling and other research tasks. It will also take on commercial work such as offshore wind power maintenance and subsea engineering support.
ERA marine pipes have been widely used on various ship types, including the Aframax oil tanker OASIS, the 89,000 DWT bulk carrier Jingmeng Fazhan, and now the research vessel Haiying Jiake. Our pipes serve key systems such as ballast water treatment, water treatment and domestic plumbing on upper decks.
Looking ahead to the ocean, ERA will keep investing in R&D and market development for marine piping. We will provide high-quality pipe supporting products for more ship types and marine engineering equipment, helping China's marine industry sail further across the deep sea.
