As well as having temperature sensors located in the cargo holds some reefer vessels are also fitted with ethylene sensors. Why is it useful to have information regarding the ethylene content in a reefer vessel cargo hold when carrying fruit cargoes?

Some fruit cargoes are sensitive to ethylene and the quality of the cargo can deteriorate as they may over-ripen.
The ethylene content can be used as a guide as to when air change fans need to run.
The ethylene content is beneficial to perishable cargoes in transit so the content needs to be monitored in case the level falls.

Why shall you never pour water into hot fat?

Inert gas drawn from an in-line unit in the main or auxiliary boiler exhaust cannot normally be used in a chemical tanker carrying high-spec products. Why is this?
Because MARPOL severely restricts the cleaning to sea of tanks that have been inerted in this way, unless additional prewashing has first been carried out. This results in the generation of slops which reduce cargo carrying capacity and incurs disposal costs.
Because the gas drawn from such a source cannot be guaranteed to be below the Lower Explosive Limit.

Because connection between boiler exhaust systems and cargo containment arrangements is forbidden under the IBC Code.
