Q6
As a second engineer in a ocean going ship, what actions you will take if the specification of the bunkers received in the last port is substantially different than the old bunkers with respect to:
(16)
(a) density
(b) Viscosity
(c) Cat fines
(d) Sulphur content
(e) Water content
Reference Answer
As a Second Engineer, upon receiving bunkers with specifications substantially different from the previous supply, a systematic and cautious approach is mandatory to ensure the safety of the vessel, prevent machinery damage, and maintain regulatory compliance. The following actions would be taken for each specified parameter: ### (a) Density **1. Primary Concerns:** * **Centrifugal Separator (Purifier) Inefficiency:** If the fuel density at 15°C is close to or exceeds 991 kg/m³, conventional purifiers will lose their water seal, leading to a complete failure of separation. This allows water and solid contaminants to pass to the service tank.
