Container claims reflect supply chain pressures

The effects of increased volumes of tank containers used to trade chemicals and other liquids on the primary east-west trades have altered the risk profile of damage to such units, according to analysis from TT Club, which insures over 50% of the global tank container fleet.

While in previous years there has been a consistent dominance of contamination as the major source of losses for tank container operators, impact incidents are now the foremost causation (at 36%). Internal pitting (from corrosion) accounts for 27% and contamination has an 18% share.

The regional breakdown of total claims follows broadly the pattern of the trades on which tank containers are employed was 50% in Asia-Pacific; Europe at 36% and 13% in the Americas.

TT’s managing director loss prevention, Mike Yarwood said: “The most significant trend we see is the relative increase in claims originating from impact incidents and from pitting of the tank’s internal steel surface. Historically we have experienced higher levels of contamination-related claims.

“The increased occurrence of impacts involving tanks would seem to be a factor of higher container volumes handled at maritime and intermodal terminals...Some 63% of impact incidents occurring at these locations. Volume increases at terminals, and associated congestion puts additional pressure on operators of handling equipment to achieve greater throughput levels. This effect, exacerbated by many tanks being ‘super-heavy’, has elevated risk.”

RTAs are the second highest cause of impact damage to tank containers with a higher proportion occurring in the Americas (almost 50%) despite this region accounting for only 21% of total impact-related damage incidents.

Among the claims involving pitting damage, the largest proportion by far occurred in Asia (87%), and the majority involved hazardous material (59%).

“While there is a plethora of potential causes for this damage, there is currently no identifiable trend causing the increase in claim frequency. It would however be prudent for operators to be mindful of this exposure; ensuring where possible tanks are prioritised for cleaning once in an ‘empty dirty’ state and considering more regular inspections.”

The lower incidence of contamination evident in the current analysis compared with previous years can also be explained by the increased volumes of trade, capacity restrictions and the beginning of serious congestion experienced in recent years

“An assumption that one could reasonably reach, given the supply chain constraints, is that consignees are arguably more willing to accept cargoes, even where they suspect a negligible contamination issue, on the basis that replacing the product from its supplier could be complex and time consuming,” Yarwood added.

Cyber risk in the transportation industry
The connected nature of the transport and logistics industries makes them an attractive target for hackers, with potentially disruptive and costly consequences. Between June 2020 and June 2021, the transportation industry saw an 186% increase in weekly ransomware attacks. At the same time, regulations and cyber security standards are lacking – creating weak postures across the board. This podcast explores the key risks. Published April 2022.
