The Bilge Alarm Never Sounded: How Ron Jeremy Sank Under Tow

Six Hours Into the Tow, the List Began

On 1 June 2025, the 25-metre tug Ron Jeremy was towing the timber-laden barge Oscar south from Hindersön toward Piteå, in Sweden's Bothnian Bay. Six hours into the passage, the crew noticed the vessel developing a list to starboard, with water visibly accumulating on the aft deck. It should have been the first sign of a problem they could still control. It became the start of one they couldn't.

What SHK Found

The Swedish Accident Investigation Authority's investigation concluded that a large amount of water had entered one of the vessel's watertight compartments — most likely as a result of minor hull damage, in the shallow, poorly charted waters around Hindersön. That alone should have been a containable problem. It wasn't, for one specific reason: the bilge alarm in the affected compartment was not functioning. Nobody was told the water was coming in until it was already visible on deck.

From there, the investigation found the crew lacked systematic troubleshooting and had limited technical knowledge of the vessel's systems and stability. Under high workload and mounting stress, the response fell behind the flooding. The decision to abandon ship didn't come until shortly after 05:00 — hours after the list first appeared. By then, the vessel was already committed. Ron Jeremy capsized and sank stern-first while the crew were still in the process of evacuating.

The Cost of the Delay

Three of the four crew reached the barge Oscar and were rescued from there. A fourth crew member was found deceased inside the upper engine room. The vessel was towing 24-metre lengths of timber on a barge behind it, in open water, in the dark — and the emergency response that should have started the moment the list appeared instead started once the situation had already become unrecoverable.

Recommended Actions

SHK's recommendations centred on training rather than a single procedural fix — reflecting that the crew followed no written procedure incorrectly so much as they lacked the underlying technical grounding to respond fast enough:

1. Enhanced crew training, specified by the shipping company, on systematic fault-finding for flooding and developing stability problems
2. Routine, verified testing of bilge alarms in all watertight compartments, not just confirmation that the panel shows no faults
3. Training and drills that build genuine, working knowledge of the vessel's stability limits — not just familiarity with the stability booklet's existence
4. Clear, drilled criteria for when to escalate to an abandon-ship decision, rehearsed well before it's ever needed for real

How This Pattern Repeats

See How You'd Handle It

The scenario opens six hours into the tow: a slight list to starboard, water visible on the aft deck, no alarm active. Do you trust the panel, or treat what you can see as the primary evidence? Seven decision points follow, ending at the point where the abandon-ship call either comes in time or doesn't.

What This Means for Any Crew, on Any Vessel

• A non-functioning bilge alarm doesn't mean there's no flooding — it means you have no early warning. Treat any visible list or water on deck as a live emergency, regardless of what the alarm panel says
• Not knowing your vessel's stability limits in an emergency is not a small gap — it is the single factor that most determines whether a developing list can be safely managed or not
• “Systematic troubleshooting” under stress means working through a structured sequence — source, rate, compartments affected, remaining stability — not reacting task by task as things get worse
• Abandon ship is a decision made early enough to execute safely. If you're still evacuating as the vessel capsizes, the decision came too late
• Test bilge alarms as part of routine maintenance — a silent failure here removes the only warning most crews will get
