BEFORE LOADING
Prior to delivery to the shipper for stuffing, all refrigerated containers should be subject to a Pre-Trip Inspection (PTI) on behalf of the carrier, conducted by a suitably qualified person. The PTI will include a visual inspection of the container’s structure and refrigeration machinery and a function test of the plant.
In case of a failed test, the necessary repairs should be carried out before re-testing. Where stuffing is delayed or the shipment cancelled, it is recommended that the carrier’s procedures stipulate the maximum validity of a PTI prior to stuffing, after which a new PTI will be necessary.
The required set-point temperature and any humidity range and/or air exchange requirements are usually stipulated on the Bill of Lading/Sea Waybill, with often only a required set-point temperature detailed. All required carriage conditions should be set prior to container stuffing and the container cooled to the set-point before being filled.
ON BOARD THE VESSEL
Refrigerated containers should be stowed allowing safe access for periodic checking and for repairs. Britannia recommends that they are stowed no higher than the second tier from the deck or lashing bridge, and when on the second tier, a properly secured and rigged working platform should be fitted along with a safe means of access.
Access for checking and conducting repairs on refrigerated containers on the second tier should be subject to a risk assessment.
We are aware of refrigerated containers being stowed three or four tiers from the deck or lashing bridge, where checking during the voyage and the provision of repairs would be unsafe, if not impossible in the case of major repairs being necessary, such as changing a compressor says Britannia Club.
Upon loading, the vessel should ensure that all refrigerated containers designated as containing cargo that is temperature controlled, should be plugged in, the plug locking collar engaged on the socket, power switched on, and the socket box access securely closed to prevent spray and water ingress.
The refrigerated container function and temperature should also be checked every six hours and records of time and date, and delivery and return air temperatures kept.
INTERNET of THINGS (IoT) TECHNOLOGY
Internet of Things (IoT) refers to a network of interconnected devices and objects connected to the Internet, and it has also been introduced to the world of refrigerated containers.
In fact, some refrigerated container operators today offer IoT as part of their service, which allows the shipper to remotely pinpoint the container’s real-time location as well as monitor and maybe even adjust some of the container’s settings.
While this is all very convenient for the shipper, it does provide some concerns to the carrier, who is ultimately responsible for monitoring the container’s performance during its voyage, particularly as the container settings can now be altered remotely and without their knowledge according to Britannia.
For this reason, the carrier needs to ensure that for containers installed with IoT technology, the contract of carriage clearly states that: - The setting instructions, which may be stipulated on the bill of lading or on the reefer manifests/instructions provided to the ship for each container, remains the legally binding instructions in terms of the container’s settings, and which the ship shall monitor during the voyage. - Changes to these instructions should be communicated in writing, so that there is a clear paper trail of the instructions provided by the shipper to the ship. - The carrier cannot be held liable for any remote changes to the settings which has not been notified to the ship as agreed by the contract. - The carrier shall not be held liable for any malfunctioning of the IoT module.
In addition, the carrier should continue to monitor the containers installed with IoT technology in the same manner as with conventional refrigerated containers to ensure that: - At loading the refrigerated container is in a good working condition and that the settings are as prescribed by the bill of lading or reefer manifest/ instructions.
- During the voyage the container continues to work satisfactorily and maintains its set values.
Any indication of error, sign of faults or changes to the container’s settings should immediately be reported to the shipper for its clarification and further instructions.
Finally, the ship should be able to document that they have monitored the refrigerated container during the voyage as required and, if there is any sign or suspicion of the container malfunctioning, preserve evidence in order to reject a potential claim.
