17NASA - Good Teams
- Good situational awareness - anticipated next
condition - Cognitive resources free - secured time to think
- Relevant information early - during time of low
workload - Built a shared mental model - a common
understanding - Conservative strategies - kept options open
- Decisions were sensitive to constraints.
Resources Environment - Explicit task allocation - clear action commands
and delegation - Monitored progress. Verbalised stratagies
Dr. Judith Orasano
18Some solutions from CRM
Focus on willingness to Manage
Trade-offs Follow Rules procedures Avoid
violations Inter-personal relations
communication Team work Understand human error
and manage it !
19Human impact limits
- Can be divided into two groups
- Physical
- Mental
- Physical
- Sleep disorder
- Fatigue
- Motivation
- Seasickness
- Speed and walking
- Drugs and alcohol
- Hunger and thirst
- Physical discomfort and pain
- Disease and infection
20- Mental
- Current and situational stress
- Change in time perception
- Perception impossibility
- Concern and anger
- Loss of memory
- Motivation
21Who dunit?
Truth about intuition
22- Seasickness can be dangerous for seamen because
it causes attention deficit. - Prevention walking restriction, nicotin,
alcohol, caffeine and salt avoidance. Do not talk
to the person who has seasickness.
23What is Stress?
- Stress is basically a physical and psychological
mechanism that starts working when we are exposed
to strain of any kind - physical, psychological
or social to make it possible for us to cope with
whatever caused the strain - it prepares the
organism to cope with the new situation..
24Two Different Kinds of Stress
25Stress Sources
- Your own personality
- Your family
- Your working surroundings
- The actual situation
26Environmental Stress
- On a ship environmental stress
- includes
- Excessive noise
- Heat
- Vibration
- Low humidity
27Personal Stress
- Cognitive disability
- Poor leadership
- High workload
- Physical disabilities
- Clumsiness
- Disorientation
- Anxiety
28Conditions Influencing on Stress Level
- Tiredness
- Time zone change
- Time of the day
- Temperature
- Uncomfortable environment
29Conditions Influencing on Stress Level
Degree of influence depends on
- Physical and mental fitness
- Experience
- Training received
- Crew composition
- training received

34Summary
- Stress is the product of a whole lifestyle. It is
not just the product of an occasional crisis! - BUT a crisis can accelerate the effects! Leading
to IQ dump - Consequently each person must learn to monitor
personal internal stress-levels (and symptoms)
and find ways to relieve such conditions!
35Stress symptoms
- Insomnia
- Interrupted sleep
- Nightmares
- Excessive sleeping
- Lack of energy
- Fatigue
- Hyperactivity
- Mood changes
- Worry
- Depression
- Stress reduces the effect of work and prevents
judgement
36Exhaustion, fatigue, sleepiness
- Them affects
- Physical rhythm
- Human clock allows vigilance through the day and
good sleep or lack of attention at night - Problems on board
- Adaptation to night work or early morning job
- Day and night changing during shifts
- Biological rhythm of most people is updated 1-2
hours per day - The human body is the most sensitive to light
around 500 a.m - Shifts in the clockwise direction Morning ?
Afternoon - It is easier to get used to the night shift than
mixed ones
37Cost of accidents
- Medical care
- Loss of productivity
- Loss of material
- Administration cost
- Costs of social help and of life quality improving
38- Sweden categorized the risk of life on
- Decks
- Embroidery
- Hatches handling
- Working at height
- Machine
- Tools handling in a limited place
- Handling with big machines and tools
- Carrying scales and ladders
- Hotel bif
- Slippery floor
- hot or sharp objects due to the rolling of the
shipOpci problemi - Ladders
- Slippery or uneven deck floor
39- Danish research shows that 50 of injuries are
related to work on the deck - Other critical activities are walking and working
in the engine room - Suggestions for improvements
- Terms of walking on the deck, scales, climbing a
ladder - Gangway and access to the ship-shore
- Assessment of safety equipment for embroidery
- Lashing
- Access Safety
- Wheelhouse enough handles and avoidance of sharp
edges
40Causes and effects of fatigue on board
- Fatigue is one of the most dangerous phenomena on
board. - It is cause of the false judgments, management
and operations. - Fatigue often occurs due to improper organization
of work on the ship, but ship's specific
environment as well, etc.
41- Fatigue is considered undesirable physical and
mental state of crew members. It is a frequent
cause of human errors that results in distress
(Figures 1 and 2) as it reduces the ability of
perception and thinking.
42- The most common causes of collisions

e/articles/106516.aspx?image151636
43- The most common causes of stranding
44- The growth of technology standards of
construction and equipment of ships and maritime
competitiveness of the market has led to the
emergence of saving the human workforce and
reducing costs at the expense of the crew.
Reducing these costs included the emergence of
hiring cheaper crews from the east. These crews
are often less educated.
45Figure 3. Structure of crew of worlds fleet by
nationality
46- Another phenomenon that follows global maritime
industry is to reduce the number of crew to
"minimum safety" given by the legislature of the
state of the vessel (Minimum Manning Document).
472. Causes of fatigue
- Fatigue is a phenomenon that accompanies human
activity, reduces operating efficiency and
adversely affects the attitude towards work. If
one looks through the production, fatigue is
defined by reducing the performance over time. - Crews often do more contracts for small amounts
of money. Time longer contracts of seamen mean
increased fatigue arising from such relationships
and lifestyle.
48- Studies have shown that the speed of doing
business increases with shorter working day.
During a long day of work worker fights fatigue
actively by frequent and longer breaks and a
slower pace of work. Lengthening of working time
significantly increases the negative effects of
fatigue.

52- The ILO and the ITF do not allow exceeding the
scheduled number of hours of overtime because of
the level of safety. Therefore shipper and
administration regulate by the contract of seaman
the by collective agreement for seafarers number
of overtime hours. The overtime hours include
hours outside of working hours, which include - maneuver of the ship
- periodic maintenance and repair of the ship
- stay in the port
- enhanced marine guard because of the conditions
(low visibility, bad weather, etc.) - unadjusted schedule of stays in port and
navigation - time zone changes
- other hours outside of working hours.
53- Research have shown that except insomnia other
factors affect the fatigue - light
- noise
- vibrations
- ventilation
- temperature and
- ship movement.

55The effects of fatigue
- Fatigue has a negative impact on safe work. It
increases human error. Errors occur as a result
of lack of mental function. The immediate
effects of human fatigue are - error in the judge
- loss of productivity
- errors in decisions
- injury at work.
56- In the ship's organization fatigue effects the
occurrence of human errors, which often manifests
by - accident
- collision
- damage to the ship or cargo by environmental
pollution. Fatigue can be divided into five
categories - physical discomfort
- loss of energy
- loss of motivation
- sleepiness.
57- Fatigue affects the health of the seamen and
causes cardiovascular diseases hypertension
diabetes stomach problems insomnia.
58- In addition, fatigue affects the social aspect of
the seamen and the organizing crew and causes - problems with family
- reduces workperformance
- increases the number of errors
- increases sleepiness
- reduces teamwork
- reduces motivation
- increases physical effort.
59- The intensity of fatigue is not manifested at all
crew members the same, but it depends on - age
- lifestyles
- rhythm of life
- anamnesis
- weight
- previous working experience and habit.
60- Insomnia causes a decrease in energy, increase of
fatigue and exhaustion. Fatigue caused in the
history some of the greatest maritime accidents - Stranding the Exxon Valdez (1989)
- The fire in the cargo holds Kometik (2006)
- Stranding Algomarine (2008).
61Fatigue prevention
- Fatigue can be prevented by proper organization
of activities on board. Assessment of human
capabilities for performing the tasks is of
crucial importance. Therefore, an officer during
the organization of work on board must be
familiar with - culture of crew members
- age of crew members
- nationality
- work experience
- physical fitness
- training programmes
62- Officers are trained for work organization
through special programs Psychosociology, human
resources management of the bridge (Bridge
Resource Management-BRM) and engine room (Engine
Management team-ETM), etc. They are explained
individual, national and cultural differences of
multinational crew, their advantages and defects.
In addition, officers are taught the proper work
organization, avoiding stressful situations,
behavior in crisis situations, etc. -
63Sleeping
- Facts
- The relaxation time of the organism
- Reducing of metabolism
- Pressure, pulse and respiration decline
- The muscle tension relief
- Resting in a dream is more intense at the
beginning and lower at the end. If we wake up
before time, rest is not complete. - Rest periods for adults are on average 7 hours
and 23 minutes on working days and one hour
longer on non-working days (weekend) - Stages of sleep
- Phase 1 Transition from vigilance to sleep
- Phase 2 Sleeping with relaxing in smaller
extent - Phase 3 i 4 Sleeping with bigger relaxing,
vigilance is harder - REM phase we are dreaming, brain is active.
REM is not important for short-term but for long-
term memory. - Non-sleeping
- Overwork
- Long vigilance
- Possible disorders the day earlier
- Nightwork
64- Morning work
- Sleep interrupts clock in the final stage of
sleep - The period of sleep is often 5 hours
- Increased sleepiness in the day, especially in
the afternoon. - Increased risk of accidents
- Evening work
- No sleepiness and work is safer
- Problem can be if you start earlier next week
(shift change) - Other factors
- Long working shift (longer than 10 hours)
- Short rest periods (less than 11 hours)
- Monotonous, hard, stressful work
- Drug use (abuse)
- Sleeping problems occur in the 45 year of life
65- Antimeasures
- Sleep will be compensated by increased sleep.
- Missed night of sleep can be replaced by another
- Break of 30 minutes is required, especially if
there are messy shifts - Schedule techniques
- Night shift should not be longer than four
repeatedly - Rotation in a clockwise direction
- Maximum of 8 hours, 11 hours of rest
- If you work the night shift
- Have peace of sleeping
- Plan your sleep
- Slumber before shift
- Avoid heavy meals, especially carbo hydrates and
fiber food - Avoid taking fluids before sleeping
- Measures against fatigue
- Change your work
66- Caffeine stimulates alertness (Coca-Cola, tea
contains 1/3 the caffeine of regular coffee). The
normal dose of coffee gives vigilance. The effect
lasts 6 hours, and the maximum effect gives the
first cup. - Nicotine is a stimulant. Smokers are worse
sleepers than non-smokers. - Alcohol increases sleepiness.
- Sleeping and anti-seasickness pills increase
sleepiness. - The suppression of deep sleep has a negative
impact.
67Dangerous minds
68 69Organization rules
- 3 truths
- Sea is dangerous
- You cannot change the rules of nature
- Men can go wrong
70- The Master does not use proper human resources,
only one man on the bridge.
71Event awareness on the ship
- It is important to have it, so the following
should be considered - Time (past or required)
- Position
- Speed
- Automatism
- Resources
- Personality, health, attitude
72- Frequent questions
- Take information-What is happening?
- Answer- What does it mean for you and the ship?
- Foresight- What can happen?
- Examples noone is navigating the ship, veering
of the ship, information quality, susceptibility
