Taizhou, a manufacturing hub on the coast of the East China Sea, once again witnessed a historic breakthrough in China's marine scientific research equipment.
On May 5, 2026, the first 3500 ton ocean comprehensive scientific research vessel "Haiying Jiake", fully invested by private funds and independently built by China, was successfully launched in Wenling, Taizhou, Zhejiang.
The total length is 82 meters, the width is 18 meters, and the full load displacement is 3500 tons. It is equipped with full electric propulsion and DP2 high-precision dynamic positioning system. 36 fishermen and ship owners raised 150 million yuan to invest in the construction, filling the gap in the participation of domestic private forces in the construction of deep-sea scientific research equipment.

Cold and hot water supply system for daily life on ships
Undertaking the water supply guarantee for all personnel on board.
The PP-R pipes used in ships have high strength, corrosion resistance, and chlorine disinfection resistance. They can be used to replace water and components for a long time, and can be moved in three directions. The 6-hot water circulation design ensures continuous hot water supply and prevents bacterial growth, reducing maintenance needs throughout the entire life cycle with a reliable long-term pipeline solution.
Lightweight pipeline, freeing up space for scientific research equipment
The planning, financing, construction, and assembly of the "Haiying Jiake" ship are all led by private entities. The PP-R pipeline used by the ship is only one ninth the weight of steel pipes, contributing considerable weight reduction space to the entire ship's pipeline system.
Efficient laying, suitable for tight construction periods
The PP-R pipeline used in ships adopts hot melt connection technology, which does not require additional connection accessories and has high efficiency in laying in narrow spaces. The ERA technical service team actively cooperated during the pipeline installation phase to ensure the timely completion of the pipeline system.
Due to the sinking of the lights in the sea, the connection between the security officials is reliable
Offshore operations may encounter harsh sea conditions, and the PP-R pipeline used by ships has a certain degree of impact resistance. The hot melt interface can maintain a connected state in vibration environments and adapt to the actual environment of offshore operations.
Stable hot water delivery, reducing the energy consumption burden on ships
The PP-R pipeline used in ships can withstand a continuous high temperature of 95 ° C, with minimal heat loss when transporting hot water. For scientific research teams that need to perform tasks continuously at sea for dozens of days, it is a key support for ensuring quality of life.
Anti scaling and anti-corrosion, escorting the water quality of distant waters
Faced with the ever-changing environmental media in the global unlimited navigation area, the PP-R pipeline used by the ship is corrosion-resistant and not prone to scaling, ensuring continuous water flow and guaranteeing daily water supply for personnel on board.
According to the plan, after the launch of the "Haiying Jiake", a two month period of outfitting construction and equipment commissioning will be carried out. It is expected to conduct a trial voyage in July this year. After being put into operation, it will undertake scientific research tasks such as marine resource exploration, seabed terrain mapping, and marine biological sampling for universities and research institutes, while expanding market-oriented businesses such as offshore wind power operation and maintenance, and seabed engineering support.
From the Aframax oil tanker "OASIS" to the "Jingmeng Development" 89000DWT bulk carrier, the "Tianyi Navigator" Wuzhou Heavy Industry cable laying ship, and now the "Haiying Jiake", the pipelines used by ERA Ship have covered various types of ships such as oil tankers, bulk carriers, and scientific research vessels, delving into key links such as ballast water systems, water treatment systems, and upper building living area pipelines.
Facing Deep Blue, ERA will continue to increase its research and market investment in the field of shipbuilding, providing high-quality pipeline support for more ship types and marine engineering equipment, and helping China's marine industry sail further into the sea.
