A recurring pollution risk involving overboard piping routed through fuel oil tanks, following two further incidents involving a similar arrangement.
In both recent cases, Oil Discharge Monitoring Equipment (ODME) overboard discharge pipes passed through bunker fuel tanks before terminating at the ship’s side, allowing fuel to escape overboard after the pipe sections failed.
The incidents follow an earlier case in which a deck scupper drain pipe routed through a fuel oil tank developed a defect, allowing bunkering fuel to enter the damaged pipe and discharge into the sea.
Although all three incidents involved tankers, the recurrence of this failure mode across unrelated vessels highlights a broader risk. These incidents demonstrate how seemingly isolated overboard piping can create a direct pathway between an oil-containing tank and the sea if the pipe loses its integrity.
ODME overboard pipe failures
In both recent cases, the section of ODME overboard discharge piping located within a bunker tank failed. Bunker fuel entered the damaged pipe and escaped directly into the sea.
Importantly, the discharge occurred despite the ODME overboard valve being closed and the removable spool piece having been removed inside the vessel.

Oman has evacuated 16 crew members from the Saudi-owned tanker Sidr following an Iranian attack in the Strait of Hormuz, according to Oman’s Maritime Security Centre.
The Sidr, operated by Saudi shipping company Bahri, was one of two supertankers carrying Saudi oil hit while transiting the Strait on 31 August. Saudi Arabia said on September 3 that two Filipino seafarers were killed in the attack. The tanker was carrying 25 crew members, with 16 now evacuated and seven still unaccounted for.
A report of an incident approximately 24 nautical miles northwest of Port Rashid, UAE.
UPDATE: A seafarer was killed in an incident involving the now identified Gibraltar-flagged oil products tanker Hercules Star while the vessel was at anchor off Dubai, its charterer, Peninsula, confirmed. “It is with deep sadness and regret that we confirm one fatality,” Peninsula said in a statement, without providing further details on the circumstances surrounding the death.
Initial assessments from maritime security sources indicate that the tanker may have been struck by a drone.
