15 Mobile JY-H130 Units Enable Flexible Fueling Filtration
Marine Diesel (Shipping Fleet Management)
Key outcomes
- High mobility and flexibility: Mobile design, single unit can serve multiple fueling ports and oil tanks
- Maintenance simplified by approximately 50%: Modular design reduces daily maintenance workload by about 50% (customer feedback)
- Secondary contamination effectively controlled: effectively controls the risk of secondary contamination during new oil fueling
Case Study
Stage 1 · Customer Problem
An Asia-Pacific shipping group operates a fleet of ocean-going cargo vessels active on global routes. To ensure that multiple core cargo vessels can achieve ISO 8217 quality requirements when fueling at different ports, the group decided to customize a highly mobile filtration solution for each vessel. When managing fuel cleanliness, the ship operator was constrained by the fixed nature of traditional equipment.
🚢
Non-fixed Fueling Points
Vessel fueling port positions vary, and fixed filtration systems require complex and expensive piping to reach every bunkering station.
🛢️
Uncontrollable New Oil Quality
Even newly purchased light diesel (MGO) often contains substandard particles and moisture introduced during barge transfer.
🔧
Space & Maintenance Limitations
Engine room space is precious, and the crew prefers equipment that is "ready to use" without cumbersome installation and commissioning.
💰
High Maintenance Costs
Existing filtration equipment has complex structures; cartridge replacement requires specialized tools and is time-consuming, increasing crew burden at sea.
Stage 2 · Fuel Analysis · NEW
Laboratory sampling of barge-delivered marine gas oil (MGO) across multiple vessels confirmed chronic particulate and free-water contamination well above ISO 8217 Category DM limits. The analysis below summarizes the fleet baseline before treatment versus the post-treatment target achieved by the JY-H130 mobile units.
| Indicator | Before Treatment | After Treatment | Target / Standard |
|---|
| ISO 4406 Cleanliness | ~22/20/17 | 14/12/9 | ISO 4406 ≤ 16/14/11 |
| Free Water (ppm) | ~350 | < 80 | < 200 (ISO 8217 DM) |
| Visual Appearance | Hazy, suspended particles | Clear & bright | Clear & transparent |
| TAN (mg KOH/g) | ~0.45 | 0.08 | ≤ 0.5 |
| Particle Composition | Rust, sand, soot & salt aggregates | Isolated inert particles | — |

Stage 3 · Solution
We provided the group with customized JY-H130 mobile filtration purification units. Equipped with heavy-duty omnidirectional locking casters and an ergonomic trolley base, the crew can easily deploy each unit at deck fueling ports or alongside engine room daily service tanks, locking it in place during voyages. The polymer rigid composite membrane delivers 5 μm precision with gas-pulse regeneration (with brief 5-15 min safety pause), and the quick-open structure allows cartridge change without dismantling piping.

Stage 4 · Results
The deployment of 15 JY-H130 mobile units provided the fleet with exceptional operational flexibility. Crew members could reposition equipment as needed across deck fueling ports and engine room tanks, achieving full-process quality control from fueling to storage. Since the composite membrane cartridges support gas-pulse regeneration (with brief 5-15 min safety pause), replacement cycles were significantly extended, improving in-port turnaround efficiency. After installation, the failure rate of the vessels' precision injector components decreased noticeably.

| Precision Injector Failures | Elevated | Noticeably decreased | Lower repair cost |
| Secondary Contamination Risk | Present during fueling | Effectively controlled | Full-process QC |
Stage 5 · Lessons Learned · NEW
Key takeaways from the fleet-wide deployment that are transferable to other multi-vessel, multi-port fueling operations.
✅
Mobility-First Design
Mobile units that serve multiple fueling ports and tanks are ideal for fleet management, eliminating fixed piping complexity and matching the non-fixed nature of vessel bunkering.
⚠️
Salt-Spray Environment Hardening
For marine applications, ISO 12944 C5-M anti-corrosion coating plus IP56 electrical rating are critical for long-term durability; Ex motors should be specified for hazardous fuel-handling zones.
🔄
Online Gas-Pulse Regeneration
Gas-pulse, group-switching regeneration (~32–64s/group) extends cartridge life and removes the need to dismantle piping, directly reducing crew maintenance burden at sea.

Customer feedback
The mobile design of the JY-H130 is exactly what our crew wanted. It is very flexible — whether fueling on deck or circulating oil in the engine room tanks, just push it to where it's needed. What impressed us most is that the filter cartridge can be backwashed, and when it's time for replacement, there's no need to dismantle the piping, which significantly reduced our workload at sea.
