A Ship-to-Ship (STS) Oil Transfer Hose is designed to transfer crude oil and petroleum products between vessels during offshore cargo operations. It must accommodate vessel movements, bending loads, and changing marine conditions while maintaining reliable fluid transfer performance.
Hongruntong STS Oil Hoses feature an oil-resistant rubber lining, high-strength reinforcement, and a protective outer cover. This construction provides flexibility, pressure resistance, and durability for demanding vessel-to-vessel transfer operations.
Available in nominal diameters from 4 to 16 inches, our STS hoses can be configured with different lengths, flange connections, and electrical continuity options. Working pressure, minimum bend radius, media compatibility, and vessel manifold requirements should be considered when selecting a suitable hose.
Black nitrile rubber lining is designed to handle crude oil and compatible petroleum products with an aromatic content of up to 50%.
Multiple layers of high-strength synthetic tyre cord provide pressure resistance, flexibility, and rebound resilience during marine hose handling.
The neoprene rubber cover resists abrasion, weathering, UV exposure, and oil contamination in demanding marine environments.
Built-in carbon steel nipples and flange options support connections to vessel manifolds and marine transfer equipment.
Available in electrically continuous or discontinuous configurations to meet specified STS transfer system requirements.
Hongruntong Marine STS Oil Hoses (HMSOH) feature a multi-layer construction designed for ship-to-ship crude oil and petroleum product transfer. The combination of an oil-resistant lining, high-strength reinforcement, and a durable outer cover supports flexibility, pressure resistance, and reliable performance in demanding marine transfer operations.
Component | Material / Specification | Function |
|---|---|---|
Inner Lining | Black nitrile rubber (NBR) | Designed to convey crude oil and liquid petroleum-based products with an aromatic content of up to 50%. |
Reinforcement | Multiple layers of high-strength synthetic tyre cord | Provides pressure resistance, fatigue resistance, and rebound resilience during handling and bending. |
Outer Cover | Abrasion-, weather-, UV-, and oil-resistant neoprene rubber | Protects the hose against mechanical wear and marine environmental exposure. |
Coupling System | Built-in vulcanized carbon steel nipples with galvanized ASTM A105 steel flanges | Provides connections for vessel manifolds and marine oil transfer systems. |
Flange Configuration | ANSI B16.5 Class 150 raised-face flanges; slip-on welded or weld-neck options | Other flange drillings are available on request. |
Electrical Configuration | Electrically Continuous or Discontinuous | Available in electrically continuous or discontinuous configurations |
Operating Temperature | -40°C to +80°C (-40°F to +176°F) | Stated operating temperature range, subject to media and application compatibility. |
The reinforced hose construction provides rebound resilience, helping the hose recover its circular cross-section after temporary deformation during handling. Operating conditions should remain within the manufacturer's specified limits, including applicable bend-radius requirements.

STS oil hoses are used to transfer crude oil between tankers during offshore vessel-to-vessel operations. Their flexible construction helps accommodate vessel movements and hose handling requirements.
STS transfer hoses support lightering operations in which petroleum cargo is transferred between vessels to manage vessel draft or cargo logistics. Hose diameter, operating pressure, and connection compatibility should be evaluated for each transfer arrangement.
Hongruntong STS oil hoses can be used for transferring compatible petroleum products between vessels during offshore cargo operations. Available hose sizes and flange configurations support different marine transfer system requirements.
According to the manufacturer's technical specifications, Hongruntong Marine STS Oil Hoses are designed with reference to BS EN 1765:2004 Type L15 and applicable OCIMF STS transfer guidance.
The manufacturer specifies proof-pressure testing at 1.5 times the rated working pressure, with test and material certificates provided for the applicable hose assemblies.
Each hose is permanently marked with a longitudinal orange alignment stripe, serial number, service identification, electrical status, and date of manufacture.
These markings help support hose identification, inspection, and maintenance records during marine transfer operations.
Customers can contact Hongruntong Marine to request applicable test documents, material certificates, and detailed technical specifications.
An STS (Ship-to-Ship) oil hose is a flexible marine transfer hose designed to transport crude oil or petroleum products between two vessels. It is commonly used in offshore tanker transfer and lightering operations.
An STS oil hose is specifically designed for vessel-to-vessel transfer operations, where the hose must accommodate relative vessel movements and dynamic handling loads. A cargo oil hose is a broader category used for petroleum loading and unloading operations, including ship-to-shore transfers. The exact construction and suitability depend on the hose specification.
Hongruntong offers STS oil hoses in nominal diameters ranging from 4 to 16 inches. Available lengths and pressure ratings depend on the selected hose model and application requirements.
Hongruntong's HMSOH series lists working pressure options of 15–21 bar, depending on the hose specification. The appropriate pressure rating should be confirmed according to the selected model, operating conditions, and technical documentation.
Hongruntong STS oil hoses feature an oil-resistant nitrile rubber lining, high-strength synthetic tyre cord reinforcement, and a protective neoprene rubber outer cover. The hose assembly also includes end connections selected for marine oil transfer applications.
Yes. Hongruntong offers configuration options for STS oil hose diameter, length, flange connections, and electrical continuity. Please provide your required hose size, operating pressure, transferred media, and vessel manifold specifications to request a suitable configuration and quotation.
