About Us

Our hose is fully certified to manufacture marine hoses in full compliance with OCIMF – GMPHOM 2009.

VH-MARINETECH CO.,LTD

Shenyang Sung Jin Chemical Co., Ltd combined with Shenyang No.3 Rubber Factory and Shenyang Rubber Products Factory 2009.

In 2018, industrial hose was independent from the former company and established VHMarineTech Co.,Ltd, which focus on designing, researching and manufacturing marine engineering products such as dredging products, oil hoses, deep sea mining hoses. VH devotes to be a leader in global marine engineering equipment market segment.

For decades, based on strengthening traditional dredging products, the company developed various highperformance new products. Meanwhile, the company brought in advanced marine oil hose manufacture and test technology, became the first manufacturer with independent intellectual property rights; the first manufacturer that was certified by overseas classification societies in China.

Series of dredging hoses were widely used in domestic and overseas dredging projects; the hoses were sold to South Korea, Japan, Malaysia Singapore, Australia, Egypt, Netherlands, Belgium and USA. Marine dredging hoses share the largest percentage of exports in China.

GMPHOM Certified

OCIMF 2009

Hoses can be manufactured from 6’’ to 24’’ ID (typically in 30’-35’and 40’ length, or different upon request). Pressure range is from 15 to 21 bar, in compliance with OCIMF.

The hoses have been deeply tested and now are well referenced in the most known terminals (CBM, SPM, FSO, FPSO) on worldwide basis.

Frequently Asked Questions

What are the common types of offshore hoses?

Offshore hoses come in various types, including floating hoses, submarine hoses, and transfer hoses. Floating hoses are used for ship-to-ship transfers or to connect a floating production system to a tanker. Submarine hoses are used to transfer fluids between fixed offshore structures or subsea equipment. Transfer hoses are used to transfer fluids from supply vessels to offshore platforms or drilling rigs.

What are the materials used to make offshore hoses?

The materials used for offshore hoses depend on the specific application and requirements. Common materials used include rubber, thermoplastic, or stainless steel. The hoses are typically reinforced with high-strength materials such as aramid fibers or steel wire.

What are the safety features of offshore hoses?

Offshore hoses incorporate several safety features to prevent spills or other hazardous incidents. These include breakaway couplings, emergency release systems, and monitoring systems that provide real-time information on the hose's condition and integrity.

How are offshore hoses tested?

Offshore hoses are subject to rigorous testing to ensure their safety and performance. The testing process may vary depending on the specific type and application of the hose, but generally includes the following steps:

Pressure Testing: The hose is pressurized with water or another fluid to a specified pressure, usually higher than the maximum working pressure of the hose. The hose is held at this pressure for a specified period to test its ability to withstand pressure without leaking or rupturing.

Tension Testing: The hose is subjected to tension (pulling) forces to test its strength and durability. The hose is typically clamped at both ends, and a force is applied to the center of the hose until it reaches a specified tension level.

Bending Fatigue Testing: The hose is repeatedly bent back and forth to simulate the effects of normal use and environmental factors such as waves, currents, and wind. The number of cycles and the bending radius are specified based on the intended use of the hose.

Leakage Testing: The hose is pressurized with water or another fluid, and the outside of the hose is inspected for leaks using visual or ultrasonic testing.

Electrical Continuity Testing: For hoses that incorporate electrical components, such as heating elements or monitoring sensors, electrical continuity testing is performed to ensure that the components are functioning properly.

Offshore hoses that pass these tests are certified for use in specific applications and environments, and are subject to regular inspections and maintenance to ensure their continued reliability and safety.

Offshore hoses OCIMF Certified?

Yes, offshore hoses can be certified by the Oil Companies International Marine Forum (OCIMF). OCIMF is a global organization that works to improve the safety, environmental protection, and operational efficiency of the marine industry. They develop guidelines and standards for the design, construction, and operation of offshore equipment, including hoses.

OCIMF's Hose Guide provides guidance on the selection, use, and maintenance of hoses used in offshore oil and gas operations. The guide includes specifications for hose construction and testing, as well as recommendations for inspection, maintenance, and storage.

Offshore hoses that are certified by OCIMF have undergone a rigorous testing and certification process to ensure their compliance with industry standards and best practices. These hoses are designed and constructed to meet the highest safety and performance standards, and they undergo regular inspections and maintenance to ensure their continued reliability and safety.

What are the main factors to consider when selecting an offshore hose?

When selecting an offshore hose, key factors to consider include the fluid being transferred, the operating conditions (such as temperature and pressure), the distance between the transfer points, and the environmental factors such as waves, currents, and wind. It is important to choose a hose that is designed and certified for the specific application and that meets all safety and performance requirements.
