GENERAL REQUIREMENT • General Requirement of Life Saving Appliances • be constructed with proper workmanship and materials; • not be damaged in stowage throughout the air temperature range -30°C to + 65°C; • if they are likely to be immersed in seawater during their use, operate throughout the seawater temperature range -1°C to + 30°C; • where applicable, be rot-proof, corrosion-resistant, and not be unduly affected by seawater, oil or fungal attack; • where exposed to sunlight, be resistant to deterioration; PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 2
GENERAL REQUIREMENT • be of a highly visible colour on all parts where this will assist detection; • be fitted with retro-reflective material where it will assist in detection and in accordance with the recommendations of the Organization; • if they are to be used in a seaway, be capable of satisfactory operation in that environment; • be clearly marked with approval information including the Administration which approved it, and any operational restrictions; and • where applicable, be provided with electrical short circuit protection to prevent damage or injury. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 3
MOB Marker • Man overboard marker is a device fitted on the outboard side of ship’s bridge wing attached to a lifebuoy. If any crew member or passenger falls overboard personal on board will quickly release the MOB marker which will fall into sea and float emitting orange smoke and flashing lights. The purpose of Man overboard marker is to mark the position of person fallen overboard for rescue operation. • SOLAS require at least one Man overboard marker to be mounted on each bridge wing. Man overboard marker (MOB) need to be attached to a lifebuoy weighing 4 kg with a lanyard. When there is a man over board emergency the lifebuoy and Man overboard marker must be released. Release mechanism allows automatic and manual release. • Once released the marker will float in sea attached to the lifebuoy and produce dense orange smoke for at least 15 minutes and two lights will burn for at least 2 hours as a day and night signal. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 4
MOB Marker • SOLAS require MOB marker be able to be operable from a mounting height of at least 30 M. • Potassium chlorate is the main ingredient in MOB marker. Chemical reaction of potassium chlorate with other ingredients inside generates the dense Orange smoke. • When MOB marker is transported by sea as a cargo same must be consigned as per IMDG Code regulations as it falls under classification criteria of explosives. Some of the MOB markers are classified as UN 0507 Class 1. 4 S or UN 0197 Class 1. 4 G. • However MOB markers fitted on board vessels and in its store as part of life saving appliances do not fall under the purview of IMDG Code as Regulation 2 of SOLAS Chapter VII Part A (Carriage of Dangerous Goods in Packaged Form) states the provisions of this part do not apply to ships’ stores and equipment. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 5
MOB Marker • Storage • Onboard vessel: Two units are normally required to be carried. Mounted inverted and attached to a lifebuoy. Usually positioned on each Bridge wing and need a clear, uninterrupted drop into the water. • Operation 1. Signal and lifebuoy mounted on bridge wing in ready to fire position. 2. Release locking pin and lifebuoy falls, automatically deploying marker. 3. Alternatively, manually throw lifebuoy overboard. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 6

Line Throwing Appliance PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 24
Use of Hydrostatic Release Unit • A hydrostatic release unit allows a life raft to launch automatically if there isn’t time for crew to launch it manually. • Depending on the type of emergency, a vessel could sink very quickly and with little warning. It is therefore important that every life raft should have a hydrostatic release unit fitted to the lashing that secures it. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 25
HRU Hammar Type • The white strong rope of Hammar H 20 is secured to the deck or liferaft cradle and attached to the life raft lashing with a sliphook. If the ship sinks, the water pressure will, within 4 meters, activate the sharp knife which cuts the white strong rope and the life raft will float free. As the ship sinks, the life raft painter line will be stretched and the life raft starts to inflate. The Red Weak Link™ breaks and survivors can board the floating life raft. The Hammar H 20 needs no annual service, maintenance or spare parts, but MUST BE REPLACED AFTER TWO YEARS. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 26
HRU Hammar Type PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 27
HRU Reusable Type • Hydrostatic Release Unit can be fitted to any container packed life raft from 4 – 150 person capacity, to allow unattended deployment in a sinking vessel. At a depth of between 1. 5 to four meters, water pressure depresses an internal diaphragm within the device. • This operates the release mechanism that secures the raft container to its cradle or mounting position. The life raft will then float free of the sinking vessel and rise towards the surface with the raft’s painter line paying out as the vessel continues to sink. When all the free length of painter line is paid out, the inflation mechanism of the life raft is activated, the raft inflates and continues to rise towards the surface. At this point of inflation, the weak link on the HRU breaks and allows the life raft to continue to float to the surface ready for boarding. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 28

Man Overboard Drill • Regularly practice a man overboard drill procedure so that all onboard are familiar with the correct process. • The priority when a person falls overboard is alerting the crew with a cry of "man overboard". • Immediately throw MOB marker and buoyancy to help the person stay afloat. • Throw floatation devices upwind of the MOB, so that they drift toward the man overboard. • That includes life jackets, life rings, or floating boat cushions, daytime orange smoke, dye marker, dan buoy with attached life ring, or simply anything that floats. • Shout words of encouragement, stay calm, and maintain an eye on the MOB as it is very easy to lose sight of someone in the water. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 41
Man Overboard Drill • Hit the MOB button on the GPS if available. • The skipper should brief the crew on the recovery procedure and make everyone aware of what method will be used to retrieve the MOB. • If you lose site of the MOB for more than a minute, issue a mayday call on the VHF. It can always be canceled if the man overboard is located. • While in man overboard procedure, have a crew member prepare a floating line or if a floating line is not available a line with a large loop. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 42
Man Overboard Drill • Once close to the MOB the skipper will give directions to throw a floating line to the MOB. Instruct the MOB to put the line around his body and under his arms. • Slowly pull the MOB to the boat making sure that he/she is able to keep their face above water. Do not pull them in to quickly or they could go under. • Once the MOB is alongside the boat, get them aboard. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 43
PREPARING FOR ABANDON SHIP 1. Broadcast distress alert by all available means 2. Instruct crew members to don warm clothing, life jackets and survival suits 3. Muster crews at stations and check all accounted for. 4. Distribute GMDSS radios and batteries, SARTs, pyrotechnics to survival craft PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 44
PREPARING FOR ABANDON SHIP 5. Prepare to launch survival craft and MOB boat/FRC 6. Upon instructions by the Master embark and launch survival craft 7. Ensure survival craft stay in proximity to the abandoned vessel and in close contact with each other. 8. Instigate rescue and survival procedures 9. Collect all extra food rations, blankets and water PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 45
ACTION AFTER ABANDONING SHIP a) Tie raft and net together. It is easier for searchers to find a large group of survivors than two or three adrift separately. b) Able-bodied men stay out of crowded raft and hang on the side. Ropes on raft should be sufficiently loose to permit an easy grasp. c) If the sea is rough, breath as in swimming, inhaling through the mouth, exhaling through the nose as a wave washes over you. d) Do not try to swim if raft or net is available. Save your strength. e) Keep kicking you legs and moving all parts of your body to prevent numbness which will strike in 30 seconds of inactivity in cold water. f) Beware of drowsiness, which often comes on between 15 to 45 minutes after you enter the water. g) Shivering saps strength quickly. Deep rapid breathing and moving the arms and legs will usually stop it. h) Non-swimmers are most likely to lose their heads. Encourage them and keep talking to them calmly and quietly. i) Stay calm. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 46
Survival Techniques • Your chance of survival without food and water depends on your resourcefulness and foresight to make use of the available equipment when adrift. The following are guidelines for survival and based on records told by survivors. • 1. Without water, a man in good health will live from 8 to 10 days. • 2. With water and in good health, you can live with out food for as long as 21 days. • 3. Survivors have known to live for 10 days or more on as little as 2 or 3 ounces of water per day without bodily harm. • 4. If you lack water do not eat. Your body use water in digesting and assimilating food. • 5. Abstain from both food and water for the first 24 hrs. after that ration what you have, and when that is gone, live off your body fat and protein. • 6. When fat and protein is converted to energy, water is released by the tissues and will help maintain kidney activity. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 47
Survival Techniques • 7. Keep your body protected as much as possible from sun and wind. • 8. Do not use heavy clothing in warm weather. • 9. Strenuous exercise and worry induce sweating with subsequent lose of water. • 10. By relaxing the mind and body and guarding against exposure to extreme temperatures, you can live longer on your stored energy. • 11. Do not drink sea water. Rain, ice and the body fluids of animals are the only sources of water. • 12. Remain in the water for hours at a time to prevent evaporation of water through the skin and to let the body absorb enough water to increase kidney activity. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 48
Survival Techniques • 13. The blood of birds and the body fluids of fish are drinkable and nourishing. • 14. Collect rain water in any available receptacle, using clothing, parachute or sails. • 15. Device methods before there is an actual need. • 16. In case of heavy rain, drink all you can hold when water is plentiful. • 17. Fishes are good to eat, cooked or raw. Device any means of catching them. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 49
MORALE FACTORS OF SURVIVAL • 1. High morale will help you survive; without it you may lost your hope and die. • 2. Do not let your thoughts and imagination become your greatest enemy. • 3. Keep fishing and experimenting to the limit, for activity is the best cure for depression. • 4. Be cheerful and think of your will to survive. 5. Cooperate with the group and obey your leaders. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 50
RECOVERING SURVIVORS • Try to keep sufficiently off the wind to reduce the ship’s roll and pitch and to create a lee. • Steaming slowly ahead with the recovery target secured alongside. • Craft may be damaged, lines may part, or people may fall into the water during the recovery operation, and drift astern. • Try to secure survival craft alongside if possible, to prevent them being blown away or left behind. • When lifting people, control lines should be rigged to the hoist and tended in an effort to minimize swinging. PJ SAMSON HEAD OF DEPARTMENT HND (NAUTICAL SCIENCE) 51
RECOVERING SURVIVORS • Safety lines should always be used to secure the casualty in case he/she is injured and/or falls. • If the differential movement is too violent, you will need to consider other options. • It may be possible to transfer those to be recovered to an intermediate platform such as a life raft veered down to them, or acting as a fender against the ship’s side. • It may be necessary to have them enter the water, suitably equipped with flotation aids and safety lines from the ship, to be pulled across a safety gap between the ship and the survival craft. • Ultimately, however, the only option may be to abandon the attempt at recovery and to stand by the target, supplying whatever assistance you can until a more capable recovery unit arrives or conditions ease.
