Bunkering is a high-risk operation: a fuel spill means a serious fine and an environmental incident, and all coordination between ship and bunker barge runs on an English checklist. Let’s go through the phrases an officer of the watch and an engineer need before, during, and in an emergency during bunkering.
Why it’s a critical topic
Bunkering is governed by MARPOL Annex I and requires the Ship/Shore Safety Checklist to be completed before the transfer starts. A mistranslated “reduce rate” or “stop pumping” can cause a spill within seconds — which is why communication during bunkering runs on short, unambiguous phrases rather than descriptive sentences.
Before bunkering: readiness checks
- Ready to commence bunkering — both sides confirm readiness to start
- Confirm maximum loading rate — agree the maximum transfer rate
- Agree emergency stop signal — establish how to signal an emergency stop
- Scupper plugs are in place — deck scuppers are plugged to contain any spill
- Checklist completed and signed by both parties — the safety checklist is signed off
Key commands during the transfer
- Commence pumping — start the transfer
- Increase / reduce rate — change the pumping rate
- Stand by for tank change-over — prepare to switch to the next tank
- Topping off — reduce to topping-up rate — the tank is nearly full, slow down
- Stop pumping — halt the transfer
Bunkering equipment terms
- Bunker manifold — the connection point on deck for the bunker hose
- Hose connection — the coupling between ship and barge hose
- Drip tray — a tray placed under connections to catch any drips
- Bunker Delivery Note (BDN) — the delivery document confirming quantity and grade
- Sampling point — where a fuel sample is drawn for MARPOL retention
Emergency phrases for a spill
- “We have a spill” — reporting an active spill
- “Stop pumping immediately” — halt the transfer at once
- “Close the manifold valve” — isolate the connection
- “Activate SOPEP” — begin the Shipboard Oil Pollution Emergency Plan response
How to train this English
- Read the checklist aloud between two people, the same way a watch handover is rehearsed.
- Learn abbreviations (BDN, SOPEP, MARPOL) together with their full term, not as isolated letters.
- Drill the emergency phrases separately — there’s no time to translate in a real spill.
- At interviews, be ready to explain the difference between reduce rate and stop pumping — they are not interchangeable commands.
Conclusion
Bunkering doesn’t forgive a slow translation of a command. At Sea Service we drill the bunkering checklist and emergency phrases as carefully as mooring commands and bridge reports — so English is never the weak link in a fuel transfer.
