The vessel Haiyang Shiyou 301 completed a bonded LNG (liquefied natural gas) bunkering operation for an internationally voyaging ship at Yantian Port in Shenzhen. With this operation, the cumulative bonded LNG bunkering volume of CNOOC has exceeded 800,000 cubic metres.
To date, CNOOC’s two LNG transport and bunkering vessels have completed a total of 143 bunkering operations. Among them, Haiyang Shiyou 301 has performed 69 operations with a total volume of 421,000 cubic metres, while Haiyang Shiyou 302 has performed 74 operations with a total volume of 380,000 cubic metres. Leveraging their differentiated configurations, the two vessels have established a comprehensive river‑sea integrated service network.
As the core operator of domestic bonded LNG bunkering, CNOOC’s business enjoys multi‑dimensional advantages. In terms of fleet composition, the vessels are complementary in their capabilities: Haiyang Shiyou 301, the world’s largest LNG transport and bunkering vessel, features a large tank capacity of 30,000 cubic metres, which supports continuous bunkering for multiple vessels and is well suited to meet the refuelling demands of very large international ships at coastal hub ports. Haiyang Shiyou 302, with its specialised design featuring shallow draft, collapsible mast, and ice‑class navigation capability, can access Ningbo and ports along the Yangtze River mainline, thus filling the gap in inland‑river bonded bunkering. The river‑sea integrated layout achieves full coverage of application scenarios in both coastal and inland waterways.
Currently, CNOOC’s LNG bunkering services cover multiple core ports including Shenzhen, Ningbo, Guangzhou, Hong Kong, and Xiamen. The company is concurrently capable of both jetty‑side and anchorage‑based bunkering operations, allowing flexible supply solutions tailored to vessel routes and berthing schedules, thereby effectively improving the turnaround efficiency of international ships.
The extraction of oil and natural gas cannot be achieved without separation equipment.
Shanghai Shangjiang Petroleum Engineering Equipment Co., Ltd. established in Shanghai in 2016, is a modern technology enterprise integrating R&D, design, production, and service. We are dedicated to developing separation and filtration equipment for the oil, gas, and petrochemical industries. Our high-efficiency product portfolio includes de-oiling/dewatering hydrocyclones, desanders for micron-sized particles, and compact flotation units. We provide complete skid-mounted solutions and also offer third-party equipment retrofitting and after-sales services. Holding multiple proprietary patents and operating under a DNV-GL certified ISO-9001, ISO-14001, and ISO-45001 management system, we deliver optimized process solutions, precise product design, strict adherence to engineering specifications, and ongoing operational support.
Our high-efficiency cyclone desanders, renowned for their exceptional 98% separation rate, have earned recognition from international energy leaders. Constructed with advanced wear-resistant ceramics, these units achieve 98% removal of particles as fine as 0.5 microns in gas streams. This capability enables the reinjection of produced gas for miscible flooding in low-permeability reservoirs, a key solution for enhancing oil recovery in challenging formations. Alternatively, they can treat produced water, removing 98% of particles larger than 2 microns for direct reinjection, thereby boosting water-flood efficiency while minimizing environmental impact.
Our new product——The High Efficiency Ultra-Fine Particle Desander is a liquid-solid separation device that utilizes an efficient centrifugal principle to separate suspended impurities—such as solids in produced water, seawater, condensate, fine particles in high-viscosity liquids, and catalyst powder in reactors—from fluids (liquids, gases, or gas-liquid mixtures). It effectively removes solid particles with sizes down to 2 microns (at 98% efficiency) or smaller.
The High Efficiency Ultra-Fine Particle Desander delivers high sand removal efficiency, capable of removing solid particles down to 2 microns. The equipment features a compact footprint, requires no external power or chemical additives, and has a service life of approximately 20 years. It offers online sand discharge capability without the need for production shutdown.
Proven in major global fields operated by CNOOC, CNPC, Petronas, and others across Southeast Asia, SJPEE desanders are deployed on wellhead and production platforms. They provide reliable solids removal from gas, well fluids, and condensate, and are critical for seawater purification, production stream protection, and water injection/flooding programs.
Beyond desanders, SJPEE offers a portfolio of acclaimed separation technologies. Our product line includes membrane systems for natural gas CO₂ removal, deoiling hydrocyclones, high-performance compact flotation units (CFUs), shale gas desanding，Cyclonic dewater package with produced water treatment，and multi-chamber hydrocyclones, delivering comprehensive solutions for the industry’s toughest challenges.
