Jerryborg Submarine Hose

Jerryborg submarine hoses are designed for use in harsh offshore environments. Their lining compounds are highly resistant to high aromatic hydrocarbons and remain stable under pressure surges and external compression. The hose construction has high tensile strength, strong interlayer adhesion, and excellent burst pressure capability. With an abrasion-resistant outer layer and low loss of buoyancy under pressure, Jerryborg hose is also available with an optional mechanical leak detector and lifting lugs for increased safe working loads.

Jerryborg submarine hoses are designed to meet OCIMF standards and are manufactured and tested under an ISO 9001:2015 certified quality system to ensure consistent performance.

FAQs

In marine liquid transport projects, if the pipeline needs to be laid underwater for extended periods and should not be affected by surface operations and ship activity, submarine hoses are typically chosen. These hoses are generally laid on the seabed or fixed at a certain depth for connecting vessels, offshore facilities, or shore-based pipelines. Compared to surface-floating transport methods, underwater hoses are more stable, less susceptible to external environmental interference, and more suitable for projects with continuous operation.

Jerryborg Marine’s submarine hoses are primarily used in these relatively fixed transport conditions with long operating cycles.

In actual projects, the main difference between submarine hoses and floating hoses lies in their deployment method and operating environment. Floating hoses operate on the surface, while submarine hoses are permanently submerged.

This means that submarine hoses require more consideration of water pressure, seabed conditions, and long-term immersion during design. During project communication, Jerryborg Marine typically confirms the hose’s laying depth and operating environment before deciding on the most suitable hose type.

The water depth at which submarine hoses are laid varies depending on the project. Some projects only require laying in shallow near-shore waters, while others involve transport in deeper waters.

Water depth directly impacts the hose’s structural design and selection. In actual projects, Jerryborg Marine considers water depth and operational methods to provide underwater hose configurations suitable for the specific water conditions, rather than simply using a uniform specification.

In marine transport projects, submarine hoses are primarily used for the underwater transport of crude oil, refined oil products, and other liquid media. Different media vary in flow rate, temperature, and frequency of use.

These factors all affect the hose’s actual performance. When selecting a hose, Jerryborg Marine typically considers the media characteristics and project operating methods to ensure it best meets the actual transport requirements.

Underwater operating environments are relatively complex; ocean currents, seabed conditions, and prolonged immersion can all affect the hose. Submarine hoses need to maintain structural stability during transport while adapting to environmental changes.

Therefore, in actual projects, the hose laying method and usage conditions often need to be planned in advance. Jerryborg Marine assists clients in identifying these environmental factors early in the project, ensuring the hose is best suited to the site conditions.

Submarine hoses are typically used in marine transport systems with well-defined structures and relatively fixed connections. Examples include liquid transport systems between vessels and shore-based facilities, or connections between vessels and offshore platforms, mooring buoys, etc. In these systems, the hoses operate underwater for extended periods, do not participate in surface operations, and do not require frequent repositioning. Therefore, underwater deployment is more suitable to ensure operational continuity and stability.

In actual projects, we consider the system structure, connection methods, and operational cycle to determine whether a submarine hose is appropriate. Jerryborg Marine also assists clients in confirming the rationality of underwater delivery solutions based on this information in the early stages of a project.
