MAIB Safety Digest 2/2023

SAFETY DIGEST Lessons from Marine Accident Reports

Featuring introductions by Simon Graves | Duncan Murt | Andy Murray

MARINE ACCIDENT INVESTIGATION BRANCH The Marine Accident Investigation Branch (MAIB) examines and investigates all types of marine accidents to or on board UK vessels worldwide, and other vessels in UK territorial waters.

Located in offices in Southampton, the MAIB is an independent branch within the Department for Transport (DfT). The head of the MAIB, the Chief Inspector of Marine Accidents, reports directly to the Secretary of State for Transport.

This safety digest draws the attention of the marine community to some of the lessons arising from investigations into recent accidents and incidents. It contains information that has been determined up to the time of issue.

This information is published to inform the merchant and fishing industries, the recreational craft community and the public of the general circumstances of marine accidents and to draw out the lessons to be learned. The sole purpose of the safety digest is to prevent similar accidents happening again.

GLOSSARY OF TERMS AND CHIEF INSPECTOR’S INTRODUCTION ABBREVIATIONS Welcome to the second MAIB Safety Digest of 2023. I will start by thanking Simon Graves, Duncan Murt and Andy Murray for their respective introductions to the merchant, fishing and recreational sections of this edition; their expertise ° degrees is self-evident, and their industry insights to safety help bring contemporary 2/O second officer context to the cautionary tales in the following pages. I hope you will find time to read the whole edition – there is something here for every mariner – but please AB able seaman do read the section introductions. And, when you have finished, please pass the AIS automatic identification system digest on so others can benefit too.

BWTS ballast water treatment system In his introduction, Simon Graves makes the point that technical solutions to remove or control hazards are reaching their limits, and that the solutions C/E chief engineer often lie with the individuals carrying out the tasks. In my introduction to one of last year’s safety digests CCTV closed-circuit television I wrote about precautionary thought, and Andy Murray continues that theme with his APEM acronym (appraise, plan, execute and monitor). Good precautionary thought helps avoid that sinking feeling of, CPR cardiopulmonary resuscitation I wish I had…before we left; we have all been there. However, Duncan Murt’s article about his fall overboard DC direct current demonstrates how even the most safety conscious individual can allow themselves to drift into bad habits or unsafe practices when what they are doing becomes routine and they forget to be afraid. DfT Department for Transport ECDIS Electronic Chart Display and Information System The near miss incidents in case 1 and case 6 are good examples where nothing could go wrong, until it did. Simple miscommunications or misunderstandings turned routine passings into near collisions because GMDSS Global Marine Distress and Safety System the safety margins had reduced to the point they were almost nonexistent. Next time you are considering GPS global positioning system taking a risk in an approach or narrow channel, remember the container vessel Ever Given blocking the Suez Canal and think again. kts knots The fishing section of this edition contains four instances where a member of the crew was dragged Li-ion lithium-ion overboard (cases 17, 19 and 20) or nearly overboard (case 21). Some of these had good outcomes, others LOTO lock-out/tag-out did not, but all show that the hazard of being dragged overboard during fishing operations remains ever present. There can be little doubt that wearing a lifejacket significantly improves your chances of living to m metre tell the tale; again, read Duncan’s introduction. However, if you are operating single-handed, carrying a “Mayday” the international distress signal personal locator beacon so you can raise the alarm will help ensure that others come to your rescue. And, MRCC Maritime Rescue Coordination Centre to take this introduction back to where I started, a bit of precautionary thought and avoiding a drift into unsafe practices could help prevent the accident in the first place.

The Lessons

1. Communicate → Navigational and safety communications from ship-to-ship and ship-to-shore must be precise and clear to avoid confusion and error; the use of standard marine communication phrases can avoid ambiguity. In circumstances such as this, where there was a lack of clarity among both the ferries and harbour control, closed-loop communications can ensure that messages are received and, more importantly, understood. Having a receiver repeat back the relayed information allows the sender to confirm the understanding of the message and, if necessary, relay it again. In this case, it might have prompted the port controller to reassess the intentions of the inbound ferry.

2. Equipment → The use of VHF radio for collision avoidance can be unhelpful and may even prove dangerous. In this instance, the radio communication delayed the manoeuvre and led to confusion between Figure 2: The close-quarters situation the bridge teams. Although it is useful in limited circumstances, VHF is not a collision-avoidance tool and must only be considered a navigation aid when it is appropriate to do so.

3. Monitor → Maintaining a safe watch starts before the lines are let go. Monitoring the automatic 4. Action → The inbound ferry did not communicate to harbour control that they needed to maintain identification system (AIS) and listening to VHF messages can provide an early indication of potentially headway for steerage and the strong breeze would have made waiting or loitering at the lateral buoy conflicting traffic. It was established after the incident that both ferries were transmitting on AIS and it difficult. Maintaining a higher speed to reduce drift is sometimes necessary; however, actions contrary to would therefore have been straightforward for the outbound ferry’s bridge team to plot the inbound ferry harbour control’s instructions should be communicated immediately to assess the impact on other traffic before getting underway. and maintain a shared mental model.
