The PMS –

Planned Maintenance System is a paper/software-based system which allows ship

owners or operators to carry out maintenance in intervals according to manufacturers and
class/Classification society requirements. The maintenance, primarily supervised by the
onboard personnel, is then credited towards inspections required by periodic surveys. The
planning and scheduling of the maintenance, as well as its documentation, must be made
according to a system that is approved by classification societies like American Bureau of
Shipping

2.The purpose of the Planned Maintenance System?

 To ensure that all maintenance is carried out at adequate intervals and in

accordance with the schedule in the planned maintenance system.
 To maintain and keep all engines, machinery, and technical components in good
working order at all times to avoid stoppages and maintain charter party speed and
consumption requirements.
 To avoid interruption and oversight of work by covering all of the work.
 To make a clear demarcation between onboard and shore maintenance work.

3.Types of Maintenance Procedures?

 Preventive or Scheduled Maintenance System: - In this type of system,

maintenance is carried out according to running hours, such as 4000hrs, 8000hrs,
etc., or calendar intervals like 6 months, yearly, etc., of the machinery.
Maintenance is carried out irrespective of the condition of the machinery. Parts
are replaced if scheduled, even if they can still be used.
 Corrective or Breakdown Maintenance: In this system, maintenance is carried
out when the machinery breaks down. This is why it is known as breakdown
maintenance. This method is not suitable as situations may arise where the
machinery is required in an emergency. The only advantage of this system is that
the working of machinery parts is used to its full life or until it breaks. This
system might become costly as several other parts may also get damaged during a
breakdown.
 Condition Maintenance System: In this system, machinery parts are regularly
checked. Sensors and other tools are used to assess the condition of the
machinery, and maintenance is performed accordingly. This system requires
experience and knowledge as wrong interpretation may damage the machinery
and lead to costly repairs, which may not be acceptable by the company.

4.Impact of planned maintenance system of ship is not done?

If the *Planned Maintenance System (PMS) of a ship is not properly implemented, it can
lead to severe operational, safety, financial, and regulatory consequences. Here’s a
breakdown of the key impacts:
1. Increased Risk of Machinery Failure & Breakdowns
- Without scheduled maintenance, critical ship systems (engines, pumps, navigation
equipment, etc.) may fail unexpectedly.
2. Higher Operational Costs
 Emergency repairs are more expensive than planned maintenance.
  Component replacements become frequent due to accelerated wear and tear.
3. Safety Hazards & Risk of Accidents
- Malfunctioning safety systems (firefighting equipment, lifeboats, alarms) can
endanger crew and passengers.
4. Non-Compliance with Regulations
- *Port State Control (PSC) inspections may detain the ship if maintenance records are
missing or outdated.
- Violations of ISM Code, SOLAS, MARPOL, and Class Society requirements can lead
to fines or loss of certification.
5. Reduced Vessel Lifespan
- Premature hull or machinery failure may force early dry-docking or even vessel
scrapping.
6. Poor Crew Morale & Increased Human Error
- Crew members may face higher stress due to frequent breakdowns.
- Lack of proper maintenance training or procedures can lead to incorrect repairs or
accidents.
7. Environmental & Reputational Damage
- Oil spills, emissions violations, or pollution due to poor maintenance can result in
heavy fines.
- Shipping companies may lose charter contracts or face blacklisting due to poor
maintenance records.

5.defination SOLAS?
SOLAS stands for the International Convention for the Safety of Life at Sea. It is
the most important international treaty governing the safety of merchant ships.
Established under the International Maritime Organization (IMO), SOLAS
sets minimum safety standards for the construction, equipment, and operation of ships
to ensure maritime safety and prevent accidents.

9.What is critical equipment definition?

Critical equipment on a ship refers to machinery, systems, or components whose

failure could lead to:
  Loss of propulsion or steering (risk of collision/grounding)

 Endangerment of crew/passenger lives

 Major pollution incidents (oil spills, hazardous leaks)

 Severe operational disruption (ship detention, costly downtime)

These systems are legally mandated under international conventions (SOLAS,

MARPOL, ISM Code) and must be regularly inspected and maintained.

10.requirement that one Planned Maintenance system must contain?

 The description and documentation of the Planned Maintenance system are to be
in the English language’
 Planned Maintenance program must include equipment manufacturer
requirements.
 Inventory content, (systems have to be included in the maintenance program.)
 Maintenance time intervals, (time intervals at which the maintenance jobs are to
take place)
 Maintenance instructions, (maintenance procedures to be followed).
 Maintenance documentation and history, (documents specifying maintenance jobs
carried out and their results.)
 Reference documentation, (performance results and measurements taken).
 Document flow chart, (chart showing flow and filling of maintenance documents
as planning cards, job cards).
 Signing instructions, (who signs documents for verification of maintenance work
carried out.)
