Configuration Optimization of Lazy-Wave Dynamic Umbilicals Using Random Forest Surrogates and NSGA-II

Processes
Dynamic umbilicals, as critical components connecting offshore platforms to subsea production systems, can effectively decouple platform motions through a lazy-wave configuration, thereby reducing top tension and fatigue damage.

Safety Maneuvering Envelope for Towed Line Arrays Under Steady-State Conditions

Oceans
To ensure safe and stable operation of towed array systems in complex marine environments, the concept of a Safe Maneuvering Envelope (SME) for towing maneuvers is proposed based on flexible cable dynamics theory. The dynamic equations of the towed array

Coupled Analysis of a Moored Sevan Hull by the use of OrcaFlex

, 2013
Offshore activity related to the search of energy in terms of hydrocarbons is taking place at increasing water depths. In deeper water, the effects on the floater motion from the mooring and riser systems increase significantly. Viscous damping, inertial mass, current loading and restoring effects from riser and mooring systems need to be adequately ...

Fatigue analysis and life prediction of 4.5-inch UDRIS coiled tubing

Results in Engineering
Coiled tubing (CT) is widely used in ultra-deepwater reel intervention systems (UDRIS), where cyclic bending during deployment and recovery, along with long-term subsea operation in wave–current environments, leads to both low-cycle fatigue (LCF) and ...
