Interactions between ballast & hull fouling
NettetMarine Invasive Species Transported by Vessel Hull Fouling: Potential Management Approaches. Godwin, L.S. 2005. Development of an initial framework for the … NettetAbstract: In order to study the interaction between various fouling particles and ballast, a multi-layer and multi-scale discrete element model (DEM) including the sleeper, ballast bed and the surface layer of subgrade was developed. Two typical fouling particles, the hard particles (sand) and soft ones (coal fines), are considered.

NettetBallast water is pumped in to maintain safe operating conditions throughout a voyage. This practice reduces stress on the hull, provides transverse stability, improves propulsion and manoeuvrability, and compensates for weight changes in various cargo load levels and due to fuel and water consumption. Nettet27. jan. 2024 · Main conclusions: This study suggests that the risk are very low, but plausible, that known hull fouling species could survive in the shallow benthic habitats near Australia's East Antarctica locations and suggest a precautionary approach is needed by way of surveillance and monitoring in this region, particularly if propagule pressure …
