==============================================================

1. Purposes of Reefer Inspection (PTI)

Reefer Inspection is performed to ensure that the reefer is in sound and functional conditions. Thus,
to ensure reefer service, Reefer Inspection is carried out before releasing the reefer unit to the
customer.

2. Kinds of Reefer Inspection

There are three kinds of Reefer Inspection:
(I) Regular PTI
(II) Smart PTI
(III) Special Test

(I) Regular PTI

Nature: Inspection service to ensure that a reefer is serviceable before releasing reefer to customer
for export loading.
General policy: Chill PTI is applied to the aged 9 or younger reefers in OOCL fleet, while AUTO
PTI for the reefer at 10 years or older.

 Please refer to the commission date in the machinery panel or the manufacturer’s system etc
resource, or enquire OOCL of the built year, if you are uncertain about the container age.

Terminology Also known Description

 (II) Smart PTI (also known as e-PTI)

Nature: Visual inspection service to a reefer which already passed the continuous function test of
machinery performance during previous shipment, to ensure the reefer is serviceable before
releasing reefer to customer for export loading

(III) Special Test (also Extended PTI for Special Shipment)

Nature: Special inspection service for the operation of special features of the reefer.

Terminology Details
Special test for In case of deep-frozen reefer shipment, i.e. booking temperature
deep frozen cargo below minus 23 degC (-23°C), additional testing requirements are
required.
EXCEPTION: For TK Magnum, Deep Frozen Test will be carried out
ONLY when the setting is below minus 25degC (-25°C).
CA Test In case of CA shipment, additional testing requirements are required

3.4 Inspection of RH Sensor during PTI

i. For the booking with the request of de-humidification control,

 Issue boxes aged 5 or younger for dehumidification shipment.

 If there’s NO reefer aged 5 or younger at stock, the vendor could select reefer over 5-year-old
for dehumidification booking, however, the vendor should report to OOCLMNR for pre-
approval especially when having the humidity sensor failure.
 Make sure RH sensor is to be tested via controller menu to verify the sensor accuracy. For
details, refer to OOCLMNR bulletin (OOCLMNR001)

ii. For a reefer not prepared for de-humidification booking

728779640.docx
3 of 11
  If the box aged 5 years or younger which is still covered under warranty period, don’t disable
dehumidification function as long as it is a unit equipped with RH Sensor.
 For a box at 6years old or over, specifically described as follows:

a. Thermoking reefer: needn’t inspect RH Sensor during Chill or Long PTI inspection;
refer to item 7 about how to disable dehumidification function.
b. Daikin reefer: No need to manually disable dehumidification function，as De-hum
feature will default off after Long/Chill PTI
c. Carrier Reefer: Don’t disable the humidification feature without OOCL pre-approval.

3.5 Supplementary provisions

1) Regular PTI Validity Period is 60 days, and Smart PTI validity is 30 Days

2) If the reefer has been positioned by vessels from other location and still within 60 days after
latest PTI, POL OPS Team or RFT/HKG Team might provide reefer list to POD team who are
requested to share the reefer list with the vendor and remind the vendor to check reefer carefully
during gate inspection while no PTI is required.

3) If the reefer is empty returned by the shipper due to booking cancelation or other reasons after
release for booking shipment and still within 60days after latest regular PTI, needn’t do regular
PTI again.
 If it is Smart PTI performed for one export booking, but the booking is cancelled after
booking release, the reefer needs regular PTI again once after empty return.

Except:
i. If there is a visual heavy damage of the reefer box and/or machinery. PTI is required per PTI
Application Criteria after the damage is rectified or repaired,

ii. If there is any malfunctioning report on the unit or customer’s complaint about the reefer
performance, PTI is required per PTI Application Criteria.

iii. Special request from OOCL to do PTI.

4) For all the reefers aged at or below 9, the insulation is sound without significant normal wear &
tear and the machinery is new. Thus, we only need to carry out the checking of the reefer
machinery plus the sensor checking at +0.0degC. No need to check the performance at -18degC.

5) The Conventional PTI will be carried out by PM centers, or specific vendors assigned by OOCL
for thorough checking of the reefers, with download data submitted.

6) For brand new reefer being first delivered from the factory to in-service fleet,

728779640.docx

has been idling at factory not over than 60days after commissioning date.

Except:
I. PTI is required if new reefer is empty positioned to other location while the reefer has
been idling at factory over than 60days after commissioning date.
II. If there is a visual heavy damage of the reefer box and/or machinery, or any part
missing. PTI is required per PTI Application Criteria after the damage is rectified or
repaired.
III. Special request from OOCL to do PTI.

4. Special Test Application Criteria

As the name implies, Special Test is to be carried out for Special Booking Requirement:

i. Deep Frozen Cargo booking

If there is a booking with set temperature below minus 23degC(-23oC), e.g. minus 30degC(-
30oC), the Special Test – Deep Frozen Cargo is to be carried out before issuing the box.

EXCEPTION: For TK Magnum, Deep Frozen Test will be carried out ONLY when the
setting is below minus 25degC (-25oC).

ii. CA test

If there is a booking required of CO2/O2 setting upon the customer’s requirement, CA test is
to be carried out according to the manual before issuing the box.

 Running Test (Also known as pre-cooling)

If there is a booking required of pre-cooling of reefer box upon the customer’s requirement,
the selected Reefer is to be set at the booking temperature, and to be carried out of Running
Test till arrival at booking temperature.

Pre-cooling of reefer is not recommended and subjected to endorsement of OOCL RFT/HKG

5. Procedures of Reefer Inspection (PTI)
All report forms can be found in DepotSmart.

5.1 Regular PTI

5.1.1 Chill PTI (Also known as Chilled PTI)

The procedures are automated by means of the reefer machinery’s microprocessor.

The procedures consist of:

i. Before switching on, visual inspection is carried out.
ii. After switching on, check and verify the Microprocessor settings, such as a, container number to
be correct; b. the date to be correct; c. time to be GMT, d. optional functions etc
 For Thermoking reefer aged 6-years old or above and not for de-humidification
booking, make sure the dehumidification function is disabled unless dehumidification
function is required in booking instruction. Refer to Item# 7 How to Disable
Dehumidification Function in this guideline.
iii. Select the PTI function of the Microprocessor as below and run the unit:
 For Thermoking, select “Chilled PTI”;
 For Daikin DECOS III Select “Chilled PTI”;
 For Carrier, select “Auto 3’

 In case one reefer requiring of Chill PTI just run with “Brief PTI” (TK), or “S. PTI” (Daikin), (for example,
no Chill PTI menu is found in the controller menu), it needs to set and run the unit to +0.0degC to check
stability at zero setting, or re-test according to above-mentioned step iii;

iv. After Chill PTI pass, record down the necessary readings, Calibrate/Replace sensors, if
necessary.

5.1.2 Full PTI (also known as Long PTI, formerly Auto PTI)

The procedures are automated by means of the reefer machinery’s microprocessor.

The procedures consist of:

i. Before switching on, visual inspection is carried out.
ii. After switching on, check the Microprocessor settings, such as a, container number to be
correct; b. the date to be correct; c. time to be GMT, d. optional functions etc
 For Thermoking reefer aged 6-years old or above and not for de-humidification
booking, make sure the dehumidification function is disabled unless dehumidification
function is required in booking instruction. Refer to Item# 7 How to Disable
Dehumidification Function in this guideline.
