Wallenius Wilhelmsen Ocean works closely with the Australian Authorities and takes its responsibilities to ensure that the Brown Marmorated Stink Bug is not carried to Australia and New Zealand extremely seriously. As has been previously advised BMSB has been found on more numerous of our vessels arriving in Oceania despite Wallenius Wilhelmsen Ocean’s compliance with all regulations.  The bio-security enforcement measures imposed by both Australia and New Zealand have resulted in severe service disruptions which cannot be mitigated locally, so the consequences of any contamination event are extreme.

Used Motorhomes and Caravans have been identified as high risk cargo both based on findings on our vessels, because of the potential exposure these have in high risk areas and due to their design meaning there are many areas in which BMSB may infest. Motorhomes and Caravans are often sitting in the forested areas/nature for longer periods of time in various locations and countries.  To reduce risk of loading contaminated cargo, Wallenius Wilhemsen Ocean will, with immediate effect, require Heat Treatment of all used mobile homes and caravans loading on our vessel destined for Oceania.  This policy will be in place year round.

Accordingly, used Motorhomes and used Caravans from all countries to South Africa, Reunion, Australia, New Zealand, Noumea or Papeete must be pre-treated using heat in accordance with rules and regulations from Australian and/or New Zealand authorities. Due to the construction complexity these units have with drawers and closed cabinets etc. Wallenius Wilhelmsen Ocean will be requiring Heat Treatment to ensure cleanliness, as gas fumigation might not penetrate all areas sufficiently.

The heat treatment should be completed as close as possible and maximum one week prior to loading.  For loading areas not covered by Australia/New Zealand pre-treatment requirements, treatment does not need to be performed by an Government approved treatment provider; however it must comply with the following standards: At 50°C or higher for at least 20 minutes. Note: the minimum temperature of the coldest part of the treated goods should reach at least 50 °C for at least 20 minutes and Wallenius Wilhelmsen Ocean will require copies of the treatment certificates to be submitted.  For load areas covered by mandatory treatment requirements, all documentation must be in accordance with those set by authorities in Australia or New Zealand respectively.

Any cargo already received for loading will be treated at customer expense, or the customer may request cancellation of the booking and release of the cargo. Your account manager will contact you about these new rules and provide local contacts to assist with treatment.
