Abandon Ship Alarm, Procedure, and Survival Guide

The abandon ship procedure is the most critical emergency procedure on any vessel, designed to ensure passengers and crew survive when a ship must be evacuated. It follows a meticulous structure covering everything from the alarm signal to liferaft deployment and search and rescue coordination.

This guide outlines the full process of ship abandonment, including the specific abandon ship alarm signal, SOLAS drill requirements, crew roles and responsibilities, personal survival equipment, and the step-by-step sequence for a safe evacuation.

Abandon Ship Defined at a Glance

The abandon ship refers to the emergency procedure in which everyone aboard must leave and evacuate the vessel because of a severe threat to the boat's integrity or safety. The imminent danger may result from a fire, collision, flooding, or other critical events and situations that may put the crew or the ship at significant risk and peril.

The master verbally gives the abandon ship signal to the station in charge of the ship crew using the vessel's address or PA system.

A single prolonged blast and seven shorter blasts using the ship's whistle and a similar signal on the general alarm bell of the vessel are used as the sound signal or alarm to abandon ship for everyone onboard the boat.

The alarm sounded, however, almost the same as that of a general warning. Once this is done, everyone should come to the emergency muster station, and there, the master or the chief officer who serves as their substitute will give the clear verbal order to abandon the ship.

Abandon Ship Alarm Signal

The internationally standardized abandon ship alarm consists of seven short blasts followed by one prolonged blast, sounded on the ship's whistle and simultaneously on the general alarm bell throughout the vessel.

This signal is defined under SOLAS (Safety of Life at Sea) Chapter III and is recognized across all vessel types worldwide. It differs from other emergency signals and should not be confused with the fire alarm (a continuous ringing of the general alarm bell) or the man overboard signal (three long blasts).

Once the alarm sounds:

• All crew and passengers must immediately report to their designated muster stations
• Life jackets must be donned before leaving the cabin
• The master or chief officer will issue the verbal order to abandon ship
• No evacuation begins until the order is given; the alarm alone triggers mustering, not abandonment

Abandon Ship Drill Requirements (SOLAS Chapter III)

Under SOLAS Chapter III, Regulation 19, ships must conduct abandon ship drills on a regular schedule to ensure all crew members are trained and prepared. Key requirements include:

Frequency: Abandon ship drills must be conducted monthly for all crew members. Drills should be held within 24 hours of departure whenever more than 25% of the crew has changed.

What each drill must cover:

• Muster at assigned stations: crew must report within 10 minutes of the alarm being sounded
• Correct donning of lifejackets and immersion suits
• Lowering lifeboats to the embarkation deck and starting engines for a minimum of 3 minutes
• Inspection of liferafts, hydrostatic releases, and painter lines
• Verification of EPIRB and SART activation procedures
• Emergency duties identification and post-drill debriefing

Record-keeping: Drill details must be logged in the deck log within 24 hours, noting who participated, what was covered, and any deficiencies identified.

Passenger vessels: Passenger ships must conduct a passenger muster drill within 24 hours of departure. Passengers must be shown how to reach muster stations, how to don life jackets, and what to do when the alarm sounds.

Regular drills, combined with well-maintained survival craft and life-saving appliances, are the foundation of effective maritime emergency preparedness.

Crew Roles and Responsibilities

The Master is the one who will assume the overall coordination and command of the abandon ship procedures. On the other hand, the officers are expected to oversee specific tasks, such as ensuring enough communication and accountability among the crew members.

Meanwhile, crew members should be calm and prompt in following all the instructions. They must also help passengers wear their life jackets and locate the designated muster stations.

The crew members must also aid in a liferaft or lifeboat launch. They should also report to and monitor their assigned duties, like operating the main communication points.

The communication officer should maintain communication with the liferafts, lifeboats, and the bridge. They also need to relay critical information to the respective rescue services.

Finally, the medical team should attend to all ill or injured passengers. They are also expected to coordinate with the rescue services to facilitate medical evacuation when needed.

Personal Survival Equipment

Several crucial pieces of personal survival equipment should be used during the abandon ship emergency procedure.

Emergency Position Indicating Radio Beacon (EPIRB)

The EPIRB is set off when abandoning the ship. The device provides location information and distress signals to the teams in charge of search and rescue.

Immersion Suits

Immersion suits are kept in designated spots and worn in cold waters before the ship is abandoned. These suits must also have a watertight seal to ensure optimal thermal protection.

Lifejackets

Lifejackets should be easily accessible and readily available in designated areas. These should be donned correctly, securely fastened, and adjusted snugly. Lifejackets must also have a light and whistle for signaling.

Personal Locator Beacons (PLBs)

Crew members should always carry personal locator beacons or PLBs. These are activated in the water to help the rescuers locate people easily and quickly.

Spare Batteries

All electronic devices should be regularly checked to ensure they have enough spare batteries. If the batteries are expired, they should also be replaced right away.

Muster Stations

All the muster stations should have clear markings and must be adequately communicated to all passengers and members of the crew. Muster stations are also expected to be easily accessible no matter which part of the ship one might be coming from.

There should also be a master list that will clearly outline the crew members' roles and responsibilities. The muster list must include the proper passenger accountability procedures.

Regular head counts must also be conducted to ensure everyone on the vessel is well accounted for. Even the slightest discrepancy must be reported to the bridge right away.

Liferaft and Lifeboat Launching

Preparation is always crucial for a safe and successful abandon ship procedure. Drills must be conducted regularly to ensure familiarization among crew members and passengers. It's also essential to ensure all the lifeboats are in good working order and have all the necessary supplies.

A systematic loading plan should be followed to maintain stability during the loading sequence. The crew members and passengers must also be instructed to embark in an orderly way.

Once again, ensuring that the liferafts and lifeboats are inflated and serviced before use is essential. Essential supplies should also be stored in them, including first aid kits, food, and water.

When launching a lifeboat, it's important to lower it safely from the ship to prevent suction and collision with its hull. The lifeboat should also be deployed away from the hazardous areas of the vessel. A coordinated procedure must be followed to ensure that every liferaft is deployed correctly.

Lifeboats must also follow the specific limits for occupancy to prevent them from getting overcrowded. Crew members must also be assigned to every liferaft for leadership and organization purposes.

Communication lines must always remain open between the bridge and the lifeboats. Emergencies or issues must also be reported right away. There should also be regular updates on the status of the lifeboat.

Search and Rescue Operations

Passengers and crew members can use smoke signals, flares, and other distress signals to guarantee easier and faster search and rescue operations. Signaling efforts should also be coordinated for improved visibility.

The available equipment in the lifeboat can be used to maintain communication with the rescue team. Ensure that accurate data on the ship's last known position is provided. Vessel tracking systems, including real-time AIS data used by apps like Primo Nautic, can provide rescue coordinators with a ship's last logged position, which becomes critical information for narrowing the search area during a maritime emergency.

Crew members and passengers should also be taught to use survival equipment and other basic survival techniques and methods. It's also important to emphasize the importance of staying together and conserving energy.

Conclusion

The abandon ship procedure is a cautiously orchestrated emergency procedure plan designed to ensure the survival and safety of passengers and crew members during maritime emergencies.

The crew members have pivotal roles to play during the process. Several pieces of personal survival equipment are critical to guarantee individual safety. But more than these, the orderly and proper execution of mustering and liferaft or lifeboat launch is paramount.

Through regular drills, comprehensive training, and following the outlined steps of the process, managing maritime emergencies more efficiently is now more than possible, resulting in reduced risks and ensuring that everyone on board remains safe and sound.

The steps to abandon the ship outlined above should be adhered to properly. However, remember that most of the preparation comes way long before the emergency occurs. So, be prepared from the get-go to fully prepare for what the sea has in store for you.
