On February 20th (the fourth day of the Lunar New Year), the 115000 ton Aframax tanker "OASIS" set a record for the world's largest airship launched with airbags and successfully set sail from Taizhou Port.
The Spring Festival is already the most tense time for port personnel. As a landmark ship of private shipbuilding in Taizhou, the "Oasis" is of great significance for its scheduled departure during the Spring Festival. This not only confirms the strong resilience of Taizhou's private shipbuilding industry chain, but also marks Taizhou's shipbuilding industry's key leadership in the global high-end marine equipment manufacturing field.
The Aurora oil tanker "OASIS" is classified by the China Classification Society (CCS) and is capable of navigating international unlimited navigation areas. The total length is 249.90 meters, the width is 44 meters, the depth is 21.5 meters, the designed draft is 13.6 meters, the designed speed is 14 knots, the length is equivalent to 8 football fields, the ship's carrying capacity is as high as 115000 tons, and the cargo hold capacity can easily load more than 800000 barrels of refined oil. Its specifications can be called a "sea giant"
The construction of modern large ships relies on the support of various high standard supporting systems on board. Among them, the pipeline system, as the "blood vessels" of the ship, is directly related to the performance and safety of the entire ship in terms of material selection and process level.
After strict screening by "Wanlong Shipbuilding Heavy Industry", ERA has become the pipeline supplier for the Aframax oil tanker "OASIS". Among them, the PE-RTII type pipeline for ships is applied to the entire ship's cold and hot water circulation system; The PVC-U pipeline for ships is responsible for key tasks such as black and grey water discharge, and the two types of products jointly build a safe foundation for the "oasis".
Double guarantee
comprehensive protection of water supply and drainage
To transport drinking water to various facilities and personnel on board the ship on the endless sea, the pipeline system has a significant responsibility. It is necessary to ensure efficient and smooth transmission, as well as to safeguard the hygiene and cleanliness of the water quality.
Faced with such a heavy responsibility, the PE-RTI type pipes used by ERA Ship have built a large and safe water supply network for "Oasis".
non-toxic and harmless
During the use of pipelines, harmful substances are not released, and high-quality water is used to safeguard the health and safety of every passenger and crew member.
hygienic and environmentally friendly
The pipeline fully complies with strict environmental and drinking water hygiene standards, avoiding the risk of bacterial growth and secondary pollution from the source.
The treatment of black and grey water discharge from ships is a key aspect of whether ships are environmentally compliant. These black grey waters have complex components and are prone to bacterial growth and scale formation. If the pipeline drainage is not smooth, it will not only affect the living environment on board, but may also violate international maritime environmental protection conventions. And with its material properties, the PVC-U pipes used in ships can easily cope.
Inert characteristics, safe and non-toxic due to its unique resin properties, have a significant inhibitory effect on bacterial growth. Experiments have shown that the microbial growth potential of PVC materials is even lower than that of copper pipes recognized for their antibacterial properties, and their antibacterial performance is superior.
Smooth inner wall
The Manning roughness coefficient is only 0.009, and this smooth surface combined with its antibacterial effect can effectively prevent the formation of scale, ensuring long-term unobstructed water flow.
'Multiple Performance'
Adapt to harsh marine environments
Unlike the inland environment, the marine environment can be regarded as the natural enemy of pipeline systems: firstly, the high salt and humidity air and the large amount of chloride ions in seawater can damage the surface of pipelines, causing corrosion; Secondly, sudden changes in temperature in the marine environment, whether too cold or too hot, can have a stimulating effect on pipelines
This requires the ship's pipeline system to have extremely stable impact resistance and chemical corrosion resistance in order to adapt to such harsh operating environments. In response to the above challenges, the ERA Marine Pipeline Series provides professional and reliable technical solutions.
PVC-U pipes for ships
Excellent chemical corrosion resistance can not only resist common seawater erosion on ocean going vessels, but also effectively prevent corrosion problems caused by disinfectants and other household and production products.
PE-RTII type pipes for ships
Resistant to impact, vibration, and tear, it adapts to various environmental temperature changes on the ship, ensuring the stable operation of the pipeline system in frequent vibration environments.
With a low thermal conductivity, it can operate stably in the temperature range of -40 ° C to 95 ° C and effectively resist expansion and contraction caused by temperature changes.
Material Innovation
Build a secure and convenient defense line
The installation and maintenance of ship pipelines should prioritize safety and convenience. Data shows that there were over 600 recorded ship fires in the United States between 2017 and 2020, with more than half of them originating from high-temperature hazards during welding operations. Therefore, there is an urgent need for breakthroughs in the installation and maintenance of ship pipelines, shifting towards safer and easier to maintain solutions.
The pipeline series for ships was designed with this in mind from the beginning, and a secure defense line was built through material innovation.
PE-RTII type pipeline for ships
Resin chlorine content up to 57%
Compared to other conventional plastic pipes, it is more difficult to ignite and can effectively contain the spread of flames.
Excellent aging resistance
With a service life of over 80 years, the failure rate is significantly reduced compared to ductile iron, steel pipes, and cement pipes.
high flexibility
Installation can be carried out through various connection methods such as mechanical connection and hot melt, which not only ensures construction flexibility and reliability, but also improves construction efficiency and reduces construction costs.
PVC-U pipes for ships
Lightweight quality
It can be completed through adhesive bonding, and the installation process is simple and fast, further reducing installation and usage costs.
From the soaring of Guangzhou Baiyun Airport and Lishui Airport, to the underground network of Shenzhen Metro, and now to the ocean voyage of the Aframax oil tanker "OASIS", the ERA pipeline has penetrated into the key areas of "sea, land, and air" transportation, providing reliable performance to safeguard major national infrastructure.
Looking ahead to the future, ERA will continue to increase its research and development investment and market layout in the field of shipbuilding, continuously output high-quality pipeline system solutions, and contribute solid strength to the sustainable development of the global shipping industry.
