TRELLINE is a bonded custom-built flexible hose with a long service life ensure by hydrodynamic and fatigue analysis.
TRELLINE hose is adapted to a large range of applications: OOL (oil offloading line), flowline, shallow water configuration, reeling system.
API17K is the most stringent standard applicable to a bonded marine hose. This certification basically means that, for given boundaries, we are able to accurately compute stresses & strains in any layer of any components of our marine hoses. From this simulation capability we can predict fatigue lifetime for cyclic loadings using SN curves that covers all our raw materials. This simulation capability also enable us to verify hose integrity versus extreme static load cases. During certification work, this simulation capability is compared with full scale fatigue tests and combined static load cases to validate our design tools and methodology. Finally, materials ageing and mechanical properties evolution over the time are verified through small scale tests and correlated with feedback from real applications.
