Long Term Storage

CWA provides expertise on the effects of long term storage of mineral concentrates required by, for example, the grounding of a bulk carrier which necessitated length repairs.

Potash

CWA was directed to inspect a cargo of potash which, on arrival showed evidence of water ingress. CWA was involved in the loss mitigation and arranged for the material to be treated locally.
