Manifold Safety Cover - Chem Cargoes
The horseshoe shaped stainless steel piece of apparatus as seen in these images was constructed in the ship's own workshop, and are a requirement in some Dutch ports. This ship, however, had a company policy to use them in all ports and for all cargoes.
This device fits over the manifold connection of a tanker to prevent spraying of the chemical cargo in the event of a pressure surge and subsequent failure of the gasket between the hose and manifold reducer.Click on an image to enlarge
