Launch and Recovery Systems (LARS) facilitate the safe deployment and retrieval of remotely operated vehicles (ROVs). These sophisticated systems are engineered to withstand the unique challenges posed by maritime environments, where unpredictable currents, waves, and weather can create a treacherous landscape for even the most robust machinery.

Malin Marine Consultants are experienced in undertaking deployment analysis to inform our clients of the optimal operational windows to facilitate the deployment and recovery of ROVs across a range of sea states. Utilising time-domain simulation software (OrcaFlex), we use the maximum tension noted within the umbilical for each sea state permutation, i.e. varying wave heights, wave periods, wave propagation direction and ROV position relative to the still water level, and from this produce and interpret technical data to inform your ROV deployment.

When conducting time-domain simulations, several models will be created by our team, modelling the vessel with the appropriate RAOs and using the required characteristics (mass, added mass, drag coefficients/areas, buoyancy etc.). We will consider the vessel specifications, package (ROV/TMS/Umbilical) and environment, to ensure every eventuality is considered, and deployment is completed, with all risks considered, calculated and accounted for.
