Jerryborg Floating Oil Hoses

Jerryborg Marine floating oil hose is designed for offshore oil discharge. It is a self-floating hose that transfers crude oil and petroleum products from offshore vessels and mooring systems. The floating oil hose is suitable for most media, such as oil (up to 50 percent aromatic content), water, brine, barite, cement, etc.

Jerryborg Marine floating oil hoses are designed and produced in full compliance with OCIMF standards. Our marine floating oil hoses are manufactured and tested in accordance with the requirements of ISO 9001:2015 quality standards.

Floating Oil Hose Types

Mainline Full Floating Hose

Mainline Full Floating Hose

This hose is the main pipeline of an offshore oil transfer system. It typically features a double-hull construction and a foam buoyancy layer. Its minimum residual buoyancy is at least 20%. It can be used in mooring systems such as CALM (Catenary Anchor Leg Mooring) and CBM (Conventional Buoy Mooring).

One-End Reinforced Half Floating Hose

This hose has an additional reinforcement layer at one end. Its structure is somewhere between floating and submerged hoses. It is typically used as a transition between a fully floating mainline hose and a submerged hose.

Tanker Rail Full Dumbbell Floating Hose

It is called a dumbbell hose because of its dumbbell-like shape. It is typically suspended from the side of a tanker (railing). It can move freely with the tanker’s movement. It is directly connected to the tanker’s oil transfer manifold and is therefore referred to as the “joint” between the tanker and the offshore floating hose system.

Reducer Full Floating Hose

A reducer hose can connect two hoses of different diameters, such as between a device connector and a main hose. Therefore, it is also called a “reducer.” It is used in piping systems where pipe diameters need to change, achieving a transition between pipes.

Tail Full Floating Hose

Tail Full Floating Hose

The tail pipe is the last section of the hose connected to the buoy. It is highly flexible and can accommodate the buoy’s movement. It can be used as the initial connection section between a single-point mooring buoy and an underwater hose.

Floating Oil Hose Construction

Single-carcass-Floating-Oil-Hose

Single Carcass Floating Hose

  1. The inside lining sticks tight to the metal end, and the hose layers wrap over each other nice and snug, with no air pockets.
  2. We use tough, oil-proof rubber and make the bonding area longer so it won’t leak.
    Strong polyester cords run through it to keep it sturdy and bendy without kinking or rusting.
  3. The body wires run in a single, long, spiral piece — with no welds anywhere — so it remains strong and handles bending well.
Double-carcass-Floating-Oil-Hose

Double Carcass Floating Hose

  1. It has a thick rubber skin with foam inside, so it floats without any problem.
  2. There are two layers in the hose — if one ever fails, the other’s still hanging in there.
  3. We also stuck a backup rubber tube between them, just in case anything sneaks through.
  4. Steel wires run all the way through to keep it in shape and stop it from getting floppy.
  5. Inside, it’s lined with tough, oil-proof rubber, made to handle crude oil, fuel, and whatever you throw at it.

FAQs

In practical projects, floating hoses are used when liquid transport needs to be completed on water, but laying fixed pipelines is not suitable. This is common in situations such as ship loading and unloading, ship-to-ship operations, or temporary offshore transport.

These hoses can float directly on the water surface, adjusting to changes in water level and ship position, without requiring complex fixing structures. Jerryborg Marine’s floating hoses are often used in these highly flexible operational scenarios, facilitating deployment and retrieval on-site according to actual conditions.

The biggest difference between floating hoses and ordinary transport hoses is that floating hoses must operate on the water surface for extended periods, rather than being fixed in place. Ordinary hoses focus more on the transport itself, while floating hoses also need to consider buoyancy and water surface stability.

Therefore, the structural design of floating hoses balances transport functionality and buoyancy requirements. When providing floating hoses, Jerryborg Marine considers actual surface operations to ensure the hoses are easier to control and more closely resemble real-world working conditions.

In actual operation, floating hoses not only withstand the pressure generated by the internal medium being transported but are also affected by waves, currents, and the relative motion of the vessel. The hose will experience some swaying and bending on the water surface, which is common in floating transport operations.

Therefore, certain requirements are placed on the hose structure and overall stability. Jerryborg Marine’s floating hoses are designed for common operating conditions to ensure the hose remains relatively stable during surface operations.

In practical applications, floating hoses are primarily used to transport liquid media, such as crude oil and refined oil products, on water. The properties of the transported media, the operation time, and the frequency of use will vary from project to project.

These differences will influence the specific hose selection, rather than simply applying a uniform specification. During the project communication phase, Jerryborg Marine typically considers the media type and usage method to match the most suitable floating hose solution, facilitating subsequent operations.

In actual projects, the arrangement of floating hoses is not entirely fixed. Depending on water conditions, vessel location, and operational methods, the hoses may be arranged in a straight line, in an arc, or in combination with other hoses.

This flexibility is a characteristic of floating hoses. During project coordination, Jerryborg Marine typically considers site conditions to help clients select the most suitable floating hose configuration for ease of operation.

In surface transport operations, besides focusing on the transport process itself, attention must also be paid to the management of the hose in its non-operational state. This includes the method of retrieval after operation, storage conditions, and whether there are unnecessary bends or stresses during transport.

These factors will affect the hose’s performance in subsequent operations. When providing floating hoses, Jerryborg Marine takes a practical approach, considering the hose’s performance throughout its lifespan to make it more suitable for repeated deployment in water transport operations.
