Slide 2 · SLIDE 1 OF 4
CORROSION PREVENTION
Protect the Hull. Protect Life.
Think of the hull as the ship's
primary life support system. If it fails,
nothing else matters.
01
SEAWORTHINESS & HULL STRENGTH
Corrosion wastes steel and reduces the net
sectional area available to carry loads.
Combined with fatigue cracking and stress
concentrations, severe wastage can
contribute to structural failure.
02
WATERTIGHT INTEGRITY
Corrosion can affect plates, weld connections
and stiffener edges. Progressive wastage
can eventually compromise boundaries and
permit water ingress.
03
BALLAST TANK INTEGRITY
Coating breakdown exposes bare steel to the
corrosive environment. Regular inspection,
maintenance and recoating are essential for
controlling deterioration.
KEY MESSAGE
Corrosion prevention is
structural integrity management,
not simply painting.

Slide 3 · SLIDE 2 OF 4
CORROSION &
THE MARINE ENVIRONMENT
Prevent the Failure Before It Becomes Pollution
CARGO CONTAINMENT
For ships carrying liquefied gases, maintaining cargo containment and structural integrity is essential to controlling the risk of cargo release and associated hazards to the ship, crew and environment.
MARPOL ANNEX I
Corrosion prevention and maintenance help preserve the integrity of oil cargo and associated systems, reducing the risk of accidental oil pollution.
BALLAST WATER MANAGEMENT
Corrosion, coating breakdown and sediment accumulation can make ballast tank cleaning and maintenance more difficult and can complicate compliance with applicable ballast water management procedures.
UNPLANNED DISCHARGES
Failure of corroded piping, boundaries or other systems can create pathways for accidental releases.
KEY MESSAGE
Good corrosion control protects both the ship and the marine environment.

PMS: MAINTENANCE
IS A SAFETY FUNCTION
Planned Maintenance System,
Not Just Wrenches & Oil Cans
Under ISM Code 10, the Company establishes
procedures to maintain the ship and equipment
in conformity with applicable requirements.
01
INSPECT
Inspections are carried out
at appropriate intervals.
02
IDENTIFY
Equipment whose sudden failure could
create a hazardous situation is identified.
03
MAINTAIN RELIABILITY
Measures are established to promote
the reliability of such equipment.
04
TEST
Standby arrangements and equipment
not in continuous use are tested
regularly as appropriate.
IMPORTANT
The ISM Code does not require only preventive
maintenance. Planned maintenance may include
inspection, testing, preventive maintenance,
condition monitoring and controlled corrective
maintenance.
KEY MESSAGE
The PMS keeps safety critical equipment
reliable before failure becomes an emergency.
REFERENCE

Resolution A.741(18)
