Why Choose SJ Petro for Offshore Oil Equipment?
-
Sinopec‑backed reliability – Direct subsidiary of China’s largest oilfield equipment group. Financial stability means long‑term parts and service support for the life of your platform.
-
Proven offshore track record – Not just theoretical designs. Our equipment is actively working on South China Sea platforms and international jackups. Ask for field references.
-
Full API & classification certifications – API 7K, 8C, 16D, 4F, 6A, plus ABS, DNV, BV, CCS type approval. Your regulatory pathway is clear.
-

Frequently Asked Questions (FAQ)
Q1: Do you have classification society approvals (ABS, DNV, BV, CCS)?
Yes. We can supply equipment with classification certificates from ABS, DNV, BV, CCS, and others. We work closely with class surveyors during design and manufacturing. Third‑party witness testing is always welcome.
Q2: What is the typical lead time for an offshore solids control package?
Standard lead time for a 4‑ or 5‑stage solids control system (shakers, degasser, desander, desilter, centrifuge) is 90 days from order. For a complete mud circulation system including pumps and tanks, 120–150 days.
Q3: Can you design equipment to fit an existing platform with space constraints?
Absolutely – that’s one of our specialties. Our engineers work with your platform layout drawings to design custom skids, foldable walkways, and multi‑level arrangements. We’ve retrofitted equipment onto platforms with as little as 40m² of free deck space.
Q4: What certifications do your explosion‑proof components carry?
ATEX, IECEx, and CSA (for North America) are available. Typical ratings: Ex d IIB T4 for Zone 1, Ex nA IIC T4 for Zone 2. All junction boxes, motors, and lighting meet IP56 or higher.
Q5: Do you provide on‑site commissioning and training offshore?
Yes. Our service engineers hold valid offshore survival training (BOSIET / FOET) and can mobilize to your platform or rig. We provide full commissioning, load testing, and operator training. Remote assistance is also available via satellite link.
Q6: How do you prevent corrosion in marine environments?
Our standard offshore coating system includes: abrasive blast cleaning (Sa 2.5), zinc‑rich epoxy primer (80µm), epoxy intermediate (200µm), and polyurethane topcoat (80µm). Stainless steel fasteners and 316L wetted parts are used throughout. We can also supply full duplex materials for highly corrosive produced fluids.
Q7: Do you supply spare parts for offshore equipment?
Yes – we maintain an inventory of critical spares (seals, bearings, belts, filters, boards) in Dubai (UAE), Singapore, and through our agent in Houston (USA). Standard airfreight to most offshore hubs is 3–5 days.
Q8: What is your warranty on offshore equipment?
18 months from shipment or 12 months from commissioning – whichever comes first. Extended warranty up to 5 years is available for major components (gearboxes, drums, pressure vessels).
Q9: Can I visit your factory and see a live test of offshore equipment?
Yes. Our manufacturing base in Jingzhou (Hubei, China) is open to clients. We can arrange a live demonstration of solids control systems and BOP handling units under load testing. Virtual factory tours are also available via video call.
