DeepSee® Double Carcass Floating Mainline Hose offers unmatched safety with its innovative two-layer construction. The primary layer transports fluid, while the secondary carcass acts as a backup in case of leakage. Double carcass mainline hose is born with a leak detection system, which will remind the operator that the primary carcass has failed. This kind of hose structure provides a safer working condition. The primary carcass is surrounded by the second carcass, however, they are manufactured and inspected independently. When the inner carcass burst or leak, the outer carcass won't be affected. It will continue to work as normal and react to the failure, such as showing the red warning light, so that the operator can handle the damaged hose in time. Double carcass structure not only improves work safety, but also decrease the probability of economic loss and environmental pollution. When the primary carcass fails, fluid will flow to the second carcass instead of entering the sea water. Although the remained carcass can function up to many years, damaged parts should be removed and replaced as soon as possible. Otherwise, accidents can show up anytime.
The marine floating hose from DeepSee is specifically engineered for superior buoyancy. This ensures that the hose remains stable and reliable on the surface of the water during fluid transfer, even in rough sea conditions. Whether it's transporting oil, natural gas, or LPG, this hose guarantees smooth, uninterrupted operations.
Mainline hoses are the main part of the floating transfer line on the ocean surface. The longer the entire line is, the larger the proportion of mainline hoses is. At DeepSee, they are designed to withstand tough conditions at sea. Whether in hot, UV-exposed environments or under extreme pressure, this hose resists wear, UV rays, and temperature fluctuations. Ideal for offshore oil rigs, mooring systems, or other marine applications, it ensures continuous, reliable service as one of the most durable marine hoses on the market.
Our floating hose features a double layer design that prolongs its working life. Resistant to abrasion and corrosion, this hose is built for extended use in demanding marine environments. The durable construction means fewer replacements and lower maintenance costs, making it an economical choice for marine operators.

Test Report & Technical Analysis
Import the ABAQUS static analysis results into the fatigue analysis software fe-safe, select the fatigue analysis theory, set the material parameters of each structural layer, load the above load spectrum, and we can get the fatigue analysis results.
We use finite element analysis software ABAQUS to:
- Create a detailed local model of the hose to calculate hose strength, such as cord tension, rebar stress, rubber strain
- Build a detailed hose model and calculate the bending, tensile and torsional stiffness of the hose
- Calculate cord tension, rebar stress, and rubber strain under certain loads
When designing marine hoses, we do dynamic analysis and hydrodynamic calculations with the help of OrcaFlex. Dynamic responses of marine hoses are simulated under environmental loadings like wind, currents, and waves. For hoses are applicated in mooring systems like SPM, we analyze tension of mooring lines in different sea states and mooring point’s motion and displacement under various dynamic loads.
DeepSee® Double Carcass Floating Mainline Hose is an advanced marine hose designed for use in offshore applications. This floating hose provides a high level of safety with its dual-layer structure, ensuring superior performance in harsh marine environments. As one of the leading marine hose manufacturers, DeepSee is committed to delivering high-quality marine floating hoses that meet demanding operational standards. Get in touch with us to know more.
