View Vessel

The Transit chart will display all inbound Vessels as per the filter selection to specified ports assigned to the Regulator user.  The table of vessels is listed by forecast vessel arrival times provided from our AIS data provider and is updated 4 times per day. The handle to the left of the Y-axis label allows the User to scroll through the list of vessels.  An extra level of information on vessel stay periods is also shown, with the thick bar showing the Last Port Of Call (LPOC) stay period and the thin line showing 68th percentile stay period. A User can hover their mouse over the thin line to see a pop-up box showing the 68th percentile value.

Step 2: Change Status of the Vessel as required. Nomination Status’ are used a Regulator tool to distinguish status’ of different nominations. There are 10 Status levels. 5 are System status’ and are used by Vessel-Check when a port nomination has been reviewed. The other 5 are for use by the regulatory agency responsible for the associated port nomination.

Operational Indicators

Vessel Type

Certain vessels can have an inherent biosecurity risk resulting from the nature of their operations (e.g. dredges due to their contact with the seafloor) and/or the inability of a vessel to undertake proactive biofouling management (e.g. oil rigs due to the excessive cost associated with the application of an antifoulant coating (AFC) to such an intricately large structure). If appropriate, jurisdictions can apply a level of the inherent risk associated with a particular vessel type(s). The indicator in the Vessel-Check portal intends to encourage direct liaison of the particular vessel type(s) (deemed to have an inherent risk) directly with the biosecurity management agency to ensure a proactive management solution is achieved. By default this indicator is disabled (returns a low risk), it can easily be enabled to suit a jurisdiction’s requirements.

Environmental Compatibility

The likelihood of impacts from an invasive aquatic species (IAS) is positively related to its ability to thrive in the receiving environment (1). Environmental matching (or similarity)* does provide a base indication of the potential threat a vessel may pose in transferring an IAS into the receiving jurisdiction (2). The Vessel-Check portal assesses the environmental compatibility between the Last Port of Call (LPoC) and the Destination Port (DP) by examining the similarity between environmental parameters of chlorophyll a (Chl a) (3) and sea surface temperature (SST) (4). Chl a and SST tolerances are known to be two of the key factors in determining an aquatic species range (1, 5). The portal examines the long-term monthly average Chl *a* and SST of the LPoC and DP for the arrival month of the vessel (when entering a jurisdictions port); where high environmental compatibility indicates a greater likelihood that a potential IAS could establish.

* species-traits which influence establishment likelihood are not accounted for within the metric.

Port Duration

Immersion time is important for fouling accumulation, with organism settlement being restricted when in high flow conditions (e.g. when vessels are underway) (2). The duration of a vessel’s stay in a port can influence the overall risk of the vessel transferring an invasive aquatic species (IAS), as increased residence time increases the likelihood of fouling organisms settling on a vessel hull (2,3).

The Port Duration indicator within the Vessel-Check portal examines the period a vessel stayed in its ‘last port of call’ (LPoC) compared to the vessel’s mean port stay duration. An extended stay at the LPoC beyond a vessels typical period of stay may indicate a greater likelihood of transferring an IAS to the destination port, especially if other aspects of the vessel’s biofouling management strategies are limited (e.g. expired antifoulant coating and/or no recent records of biofouling management plan implementation).

AFC DOCS shows the Antifoulant Coating information.

OPERATING PROFILE shows an average operating profile for the vessel and any Lay-Up periods.

BIOFOULING RECORD BOOK shows the vessel’s Biofouling Record Book, including both Planned Records and Contingency Records and associated evidence.

Planned Record – Always defined in Biofouling Management, for known regular actions like a 60 month Dry-dock cycle

Contingency Record – For broader and variable activities that are job or situation specific – e.g. an inspection before entry into New Zealand.  Selected when making a new record and can NOT be for a Planned activity/niche

Regulator Override

The Regulator can override (up or down) any of the 7 risk metrics which will also affect the Overall Risk Assessment.  Both the System and Regulator assessments are retained and are visible to the Regulatory and Vessel Manager User .The Regulator overridden risk levels will take precedent over the System assessment and will be presented to the Vessel Manager in the Risk Reports. (the Regulator comments will also be included in the Risk Reports).

Step 1: On the Regulator list of risk scores, select the metric to change.
