Procedure for Issuing Safe Work Permit for Ship Repair Jobs
1. PURPOSE
The use of this Permit to Work (PTW) system is for ship repair activities. This document
looks at the format of the work permit, regulations and procedures governing their
implementation.
The Permit to Work (PTW) system is a written document which authorizes persons to carry
out the work, warns of possible dangers and clearly states the precautions to be taken for the
job to be carried out safely. The work permit ensures that full consideration is given to the
hazards and risks, and that these are properly dealt with prior to the commencement of the
work.
A written Permit to Work (PTW) system provides formal written procedures and formal
actions to ensure that non-routine; potentially hazardous activities are carried out safely as
possible.
The type of non-routine work for which work permit procedures are normally required
include maintenance and repair, inspection, testing alteration, construction, reconstruction,
dismantling, adaptation, modification and cleaning by EHS approved ship repair/specialized
companies. All non-routine jobs carried out on board vessels shall hold valid permit from
TRAKHEES EHS approved ship repair surveyor.
Written work procedures, with a specific permit to each type hazard, reduces changes of
misunderstanding and ensure that supervisors take account of all foreseeable circumstances
which could arise during the repair activities concerned.
2. SCOPE
The Scope and key functions of Permit to Work (PTW) system are:
Ensuring the proper authorization of designated work. This may be work of certain
types, or work of any type within certain designated areas, other than normal operations.
Making clear to people performing the work the exact identity, nature and extent of the
job and the hazards involved, and any limitations on the extent of the work and the time
during which the work may be carried out.
Specifying the precautions to be taken including safe isolation from potential risks such
as hazardous substances and energy sources.
Ensuring that the person in charge of a repair job is aware of all the work being done.
Providing not only a system of continuous control but also a written record showing that
the nature of the work and the precautions needed have been checked (at the work site)
by an appropriate person or people.
Providing for the suitable display of permits.
EHS-PMP-12

Providing for the procedures or arrangements for work activities that may interact with
or affect any of these activities.
Providing a formal hand-over procedure for use when a permit is issued for a period
longer than one shift or when permit signatories change.
Ensure that a second and third opinion is obtained, where necessary, to prevent errors of
judgment or taking of short cuts which may increase the risk.

Work (PTW) system should receive instructions on the specific procedures as they
apply on the installation where they are to work. This should consist of a general
overview of the Permits to Work (PTW) system and their specific workforce member
responsibilities.
9. DOCUMENTATION
The Permits to Work (PTW) system will include critical procedures and it is therefore
important that the documentation associated with the Permits to Work (PTW) system be given
a suitable level of importance. The following points shall be confirmed during the process.
The Permits to Work (PTW) system documentation should be:
Specific and well detailed for the type of work to be carried out.
All required fields shall be adequately filled in as per the requirement.
Any overwriting or changes shall be counter signed by the Responsible Persons.
All relevant supporting documents shall be attached along with the original permit.
10. COMMUNICATION
The importance of effective communication within the Permits to Work (PTW) system cannot
be overstated. Due to the number of people who may be involved in the work and the
potentially large number of interfaces, this is one of the most important areas of the system.
Areas of specific emphasis include:
Performing Authority shall state clearly the exact nature and scope of the work, the
number of workers, different trades and special tools involved.
Surveyor shall communicate clearly the potential hazards at the worksite, the
precautions he has taken and the precautions to be taken by the person in charge of the
EHS-PMP-12
Revision: 00 Dec 2016 Page 7 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
work. He should also ensure that any other person(s) who may be affected by the work
is informed.
Issuing Authority shall communicate clearly to the members of his work party the
information received on hazards and precautions and the action required in the event
of an emergency. Issuing Authority should inform Surveyor, if there are changes in the
work conditions which may affect the validity of the permit at the time of
opening/renewing permit.
11. CO-ORDINATION
It is important to ensure that work activities, requiring Permits to Work (PTW) system, are
planned and coordinated in order to avoid risks caused by simultaneous activities. This
coordination is best achieved by having one person, usually the Safety Officer, control the
permits to work. On major repair jobs it may be necessary to delegate this responsibility to
more than one person. The delegated responsible persons would be responsible for the single
point coordination of work activities within their own well defined areas and for informing
others where the work may infringe on another area. The Safety Officer should retain overall
responsibility for coordinating activities between the different delegated areas.
12. PLANNING
Careful planning of work requiring a Permit to Work (PTW) system should take place to
ensure:
Appropriate approval for the work.
All persons in charge of areas which may be affected are made aware and hence
take precautions against possible interaction with other work activity.
Sufficient time to identify all potential hazards, implement precautions and prepare
the worksite.
13. PREPARATION
13.1 Preparation before Issuance of Cold Work Permits.
Lines, valves and any other equipment may have to be completely depressurized
and drained before work on them can be started. Connected piping may require
isolation by blinding. All necessary bleeders and vents shall be opened before a
permit is issued.
Some of the more important aspects are listed on the work permit form such as:
Equipment isolated from motive power: electricity/air/water and tagged.
EHS-PMP-12
Revision: 00 Dec 2016 Page 8 of 25

In case of scale: Pyrophoric substances removed, contained and kept wet.
Proper work platform/access/emergency exits provided.
Adequate suitable lighting for the job and for emergency provided.
Safety belt/full body harness/life jacket provided for persons working at
heights.
13.2 Preparation before Issuance of Hot Work Permits.
The list of typical hot work is attached in the appendix for ready reference. The
persons authorized to issue hot work permits are personally responsible for ensuring
that the site, the equipment, vessels, lines or other equipment covered by the permit
are properly prepared to eliminate the risk of fire explosion or exposure to toxic
gases.
Any precautions required must include such items as :
Disconnecting lines, blinding and isolation.
Freeing the equipment of product and/ or gases.
Cleaning and removal of flammable/ combustible materials.
Determining the suitable location for welding or other hot work equipment.
The covering of sewers, ditches or drains/ vents etc.
Removal or wetting down of scaffolds, asbestos and wooden floors, decks
and platforms.
Making provision for fire protection and fire guards as appropriate/ necessary.
Authorized person, prior to the issue of the hot work permit shall carry out a
gas test.
Note that if hot work is not started within one hour of satisfactory gas test, or has
been discontinued for that period of time, then other test shall be carried out unless
specifically authorized by the issuing authority and / or the performing authority.
13.3 Preparation before Issue of Confined Space Entry Permits.
The persons authorized to issue hot work permits and cold work permits are
personally responsible for ensuring that the confined Space covered by the permit
are properly prepared to eliminate the risk of fire explosion or exposure to toxic
gases.
Any precautions required must include such items as
EHS-PMP-12
Revision: 00 Dec 2016 Page 9 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
Before any enclosed space is entered, it should be well ventilated by releasing
as many openings as possible. Ventilation should be continuous where
possible because in many enclosed spaces the hazardous atmosphere forms
again when the flow of air is stopped.
Isolating the space whereby the space is removed from service by one or more of
the following:
Locking out electrical sources, preferably at disconnect switches remote from
the equipment.
Blanking and bleeding, securing valves – cargo, steam, ballast, inert gas
system, Pneumatic, hydraulic and fuel oil lines, etc. The inert gas branch, cargo
lines and heating coils should be blanked off.
If workers are to enter a tank or space with an inert gas arrangement. The
appropriate blanking is to be checked at each tank if entry is required while
inerting, or if gas freeing of other tanks is taking place, or if any other tanks are
inerted or contain hydrocarbons.
An alternative to pipe blanking is to remove a section of the branch line.
Disconnecting mechanical linkages on shaft-driven equipment where possible.
Securing mechanical moving parts in enclosed spaces with latches, chains,
chocks, blocks, or other devices.
It’s important that the workers are warned that the space is enclosed and that entry
requires an entry permit and authorization to enter. Performing Authority shall
ensure that appropriate warning signage is used.
14. GAS TESTING
Permit to Work (PTW) preparation may involve a consideration of the likely presence of
flammable or toxic gases, or oxygen deficiency/enrichment, at the worksite. Where such a
consideration is necessary then gas testing should be undertaken.
Gas tests carried out prior to entry into the space should reflect the contaminants that can
reasonably be expected to be present within the space, taking into account the previous
cargo carried, ventilation of the space, coatings in the space and any other relevant factors.
When preparing for entry into a ballast tank or void space where hydrocarbon vapors may
not normally be present, it is prudent to test the space for hydrocarbon vapor or H2S if the
space is adjacent to a cargo or bunker tank. This is particularly important if entry is being
made to investigate the possibility of bulkhead defects.
Testing shall be conducted by the EHS Approved Surveyor during cleaning or cold work to
assure that air concentrations are Under 1% for vessels (other than tankers) and 0% for
Tankers of the Lower Explosive Limit and within the PELs and below IDLH levels.
Factors such as, but not limited to, temperature, volatility of the residues and other existing
EHS-PMP-12
Revision: 00 Dec 2016 Page 10 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
conditions in and about the spaces are to be considered in determining the frequency of
testing necessary to assure a safe atmosphere.
Flammable vapor is maintained under 1% for vessels (other than tankers) and 0% for
Tankers of the Lower Explosive Limit; and Spaces containing highly volatile residues may
require additional ventilation and continuous monitoring to keep the concentration of
flammable vapors under 1% for normal vessels and 0% for Tankers of the Lower
Explosive Limit and within the permissible exposure limit.
Persons involved in gas testing should be adequately trained in the use of gas testing
equipment, and in the interpretation of results.
The responsibility of what to test for, where to take samples, and the minimum number of
samples to take should lie with the permit issuer. Gas testing should be done as close to the
commencement of work as possible.
Results of any gas testing should be recorded and timed, and entered on the permit - if
levels change during the work, the permit should be suspended.
Test(s) Permissible entry level
Percent of oxygen 19.5% TO 23.5%
Lower flammable limit (LEL) Under 1% for vessels (other than Tankers) and 0% for Tankers
Carbon monoxide +35 PPM
Hydrogen Sulfide +5 PPM *15 PPM
* Short-term exposure limit : Employees can work in the area up to 15 minutes.
+ 8 hour Time Weighted Average : Employees can work in the area 8 hours (longer
with appropriate respiratory protection).
14.1 Potential Gases present in Enclosed Spaces
Respiratory hazards from a number of sources could be present in an enclosed space.
These could include one or more of the following:
• Hydrocarbon vapors, such as butane and propane.
• Toxic contaminants associated with organic vapors, such as aromatic
hydrocarbons, benzene, toluene, etc.
• Toxic gases, such as benzene, hydrogen sulphide and mercaptans.
• Oxygen deficiency caused by the presence of inert gas, oxidation (rusting) of
bare steel surfaces, or by microbial activity.
EHS-PMP-12
Revision: 00 Dec 2016 Page 11 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
• Solid residues from inert gas and particulates, such as those from asbestos,
welding operations and paint mists.
14.1.1 Hydrocarbon Vapours
During the carriage and after the discharge of hydrocarbons, the
presence of hydrocarbon vapor should always be suspected in enclosed
spaces for the following reasons:
• Cargo may have leaked into compartments, including pump
rooms, cofferdams, permanent ballast tanks and tanks adjacent
to those that have carried cargo.
• Cargo residues may remain on the internal surfaces of tanks,
even after cleaning and ventilation.
• Sludge and scale in a tank that has been declared gas free may
give off further hydrocarbon vapor if disturbed or subjected to a
rise in temperature.
• Residues may remain in cargo or ballast pipelines and pumps.
The presence of gas should also be suspected in empty tanks or
compartments if nonvolatile cargoes have been loaded into non-gas free
tanks or if there is a common ventilation system which could allow the
free passage of vapors from one tank to another.
Toxic contaminants could be present in the space as residues from
previous cargoes, such as benzene or hydrogen sulphide.
To be considered safe for entry, whether for inspection, cold work or
hot work, a reading of less than 1% LFL must be obtained on suitable
monitoring equipment.
14.1.2 Toxic Gases
14.1.2.1 Benzene
Checks for benzene vapor should be made prior to entering
any compartment in which a cargo that may have contained
benzene has recently been carried. Entry should not be
permitted without appropriate personal protective
equipment, if statutory or recommended TLV-TWAs are
likely to be exceeded. Tests for benzene vapours can only
be undertaken using appropriate detector equipment, such as
detector tubes.
Detector equipment should be provided on board all vessels
likely to carry cargoes in which benzene may be present.
14.1.2.2 Hydrogen Sulphide
Hydrogen Sulphide (H2S) is present in crude oils in varying
concentrations. Where the concentration is high, the crude is
EHS-PMP-12
Revision: 00 Dec 2016 Page 12 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
often referred to as ‘sour’ crude. H2S may also be present in
fuel oil and bitumen products.
H2S is very soluble in water. General practice and
experience indicates that washing a tank with water after
carrying a cargo containing H2S should eliminate the
hydrogen sulphide vapour within the space.
However, prior to entry into an enclosed space which has
previously carried oil containing H2S, or where the
presence of H2S vapor may be expected, the space should
be ventilated to a reading of less than 1% LFL on a
combustible gas indicator and tested for the presence of
H2S using a gas detector tube. Care should be taken not to
rely on the use of catalytic H2S sensors which may have a
cross sensitivity with hydrocarbon vapor. Since H2S is
heavier than air, it is very important that the bottom of any
space is thoroughly tested.
When carrying a cargo containing H2S, particular attention
should be given to the possibility of the presence of H2S in
locations, such as pump rooms, deck stores and in ballast
tanks. The presence of H2S in ballast tanks has a high
probability due to the gas being drawn into the tank when
DE ballasting during the loading operation.
14.1.2.3 Mercaptans
Mercaptans are present in the vapours of pentane plus
cargoes and in some crude oils. They may also be present
where oil residues have been in contact with water for
extended periods.
The presence of Mercaptans can be detected by the use of
chemical detector tubes. Their concentration should be
reduced to 0.5ppm to avoid discomfort to personnel and
nuisance smells.
14.2 Oxygen Deficiency
Before initial entry is allowed into any enclosed space, the atmosphere should be
tested with an oxygen analyzer to check that the air contains 21% oxygen. This is of
particular importance when considering entry into any space, tank or compartment that
has been previously inerted. Lack of oxygen should always be suspected in all
enclosed spaces, particularly if they have contained water, have been subjected to
damp or humid conditions, have contained inert gas or are adjacent to, or connected
with, other inerted tanks.
EHS-PMP-12
Revision: 00 Dec 2016 Page 13 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
14.3 Products of Inert Gas
By-products of combustion when inert gas is produced from boiler flue gas or from an
inert gas generator include carbon monoxide and carbon dioxide.
Carbon monoxide is a toxic gas that may be present in cargo tank atmospheres
following gas freeing and in spaces containing components of the inert gas plant.
Carbon dioxide is not toxic but presents a smothering hazard. Adequate ventilation is
required to maintain a normal oxygen level in air of 21% by volume in the space and
to eliminate any hazard.
15. HAZARD / RISK ASSESSMENT
A critical element of the Permit to Work (PTW) system preparation stage is an assessment of
the hazards which may be associated with the work to be undertaken.
Such assessment should be carried out by the Surveyor, in conjunction with the Performing,
and Issuing Authority.
The following principles to be assessed:
Precise details of the work to be undertaken should be obtained from the task
supervisor.
Consideration should be given to any safer alternatives, either in terms of the timing,
or the intended method of performance of the work.
The “process” hazards should be considered. This will include a consideration of
hazards associated with the material being handled, and of process equipment.
The practical difficulties of carrying out the work should be assessed, if necessary
consulting the discipline specialists undertaking the work.
The possible impact of the work on the surrounding environment should be assessed.
Potential hazards to the safe execution of the work arising from the surrounding
environment should be similarly considered.
From the assessment of the hazards involved, the precautions which will have to be
taken to enable the work to be carried out safely may be deduced.
Stated below the list (not limited to) of critical hazards which shall be assessed:
Liquid or gas under pressure. Radioactivity.
Toxic materials. Moving Machinery.
Corrosive materials. Equipment generating sparks.
Flammable materials. Crane operation.
EHS-PMP-12
Revision: 00 Dec 2016 Page 14 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
Hot materials. Pressure testing.
O2 deficiency. Adjacent operations.
H2S area. Wind, weather, sea state.
Naked flames or arcs. Danger of falling. Working at heights
Flying particles or sparks. Access/egress.
Electricity Confined space.
Explosives. Substances harmful to health.
16. CROSS REFERENCE
The objective of a cross reference is to ensure that no interaction takes place between work
activities which might endanger the safety of personnel. The surveyor should, by knowledge
of work going on in his area of responsibility, be aware of potential interaction when issuing
different permits for the same piece of equipment or system, or where there may be potential
conflict with adjacent work activities.
Such situations shall be minimized by careful planning and suitable precautions which should
include an appropriate method of cross referencing the different tasks.
It may be that the interacting activities are covered by separate surveyors, in which case close
co-ordination shall be done.
17. ISOLATION
An essential ingredient of any safe system of work is the method and integrity of the isolation
procedure.
The isolation principle to be adopted, prior to carrying out maintenance or repair, will be
determined by a number of factors e.g. potential for pressure, dangerous substances, lack of
oxygen, moving machinery etc.
It is beyond the scope of this document to provide guidance on the isolation required for each
potential hazard. Each company should develop its own isolation procedures to be adopted
depending on work activity and risk involved.
The following additional points should be considered within the isolation procedures:
Complex isolations should be planned and recorded on a working drawing. This should
be discussed between the person issuing the permit and the person in charge of the work
to ensure all isolation points are clearly understood and agreed.
The marked up drawing should be readily available to all concerned, consideration
should be given to attaching a copy to the permit.
Isolation procedures should include all energy sources, i.e. mechanical, electrical,
hydraulic pressure, oil, gas, water etc.
EHS-PMP-12
Revision: 00 Dec 2016 Page 15 of 25
Procedure for Issuing Safe Work Permit for Ship Repair Jobs
Isolation should only be applied and removed on instruction from the person making the
permit (Surveyor).
If more than one task is to be carried out on the area or piece of equipment, there is a
risk that on completion of one of the tasks the isolations are removed and the equipment
is put back into service.
Controls should be in place to prevent premature de-isolation where dual tasks are
involved.
18. PROCEDURE FOR ISSUING WORK PERMIT
18.1 Issuing of Work Permit:
EHS Approved Ship Repair Surveyors shall initiate work permit and it should contain
the following information:
a. Craft, section, or contractor doing the work.
b. Type of work, and limits of work area.
c. Description of work to be performed.
d. Date and time of permit validity.
e. Indication that all checks and safety precautions are taken.
f. Any further special steps to be taken.
g. Appropriate box “Cold Work”, “Hot Work” “Confined Space Entry” shall be
ticked to indicate the type of permit.
EHS Approved Surveyor personally checks all items entered in the permit before it is
issued. The performing authority then checks all items entered in the permit and makes
sure that the area / equipment / apparatus is safe for his personnel to work in. Then the
permit (Cold Work, Hot work, and Confined Space Entry) will be submitted to the
Issuing authority for approval.
Once the Issuing authority approves the permit the performing authority can start for
execution of the job.
After a permit has been issued it is the responsibility of the performing authorities
whose craftsmen are performing the work, to ensure that all instructions and/or
limitations entered on the permit are being complied with.
After issuing the permit, the issuing and performing authority shall continue to be
responsible for the conditions prevailing throughout the validity of the work permit.
Should any changes occur in the conditions from those that have been defined on the
permit, then issuing authority shall / cancel the permit and all the concerned parties are
informed. And shall ensure a new permit has been issued upon the conditions are made
safe to carry out the proposed work safely
The permit shall be prepared in triplicate and distributed as follows:
