VesselFilter dataclass

Used to filter vessels when retrieving tonnage lists.

All attributes in this class are optional, i.e. no filtering will be performed on attributes whose value is None.

Attributes that accept a list of values are used to perform an OR comparison. In other words, when a non-empty list of values is used, the tonnage lists will contain vessels that match on any of the specified values. Using an empty list will result in no filtering being performed.

VesselFilter is mutable in order to allow making adjustments to existing instances if query results are unsatisfactory.

Attributes:

Name Type Description
push_types Optional[List[str]]

Return vessels with the specified push types. Use constants defined in the PushType class as values of this attribute.
market_deployments Optional[List[str]]

Return vessels with the specified market deployment types. Use constants defined in the MarketDeployment class as values of this attribute.
commercial_statuses Optional[List[str]]

Return vessels with the specified commercial statuses. Use constants defined in the CommercialStatus class for the values of this attribute.
vessel_subclass Optional[str]

Return vessels of the specified subclass. Use constants defined in the VesselSubclass class for the values of this attribute.
add_willing_to_switch_subclass Optional[bool]

When True, returns vessels that do not match the subclass but are willing to switch to it.
latest_ais_since Optional[int]

The maximum age, in days, of the vessel's AIS information at the time the tonnage list was captured.
operational_statuses Optional[List[str]]

Return vessels with the specified operational statuses. Use constants defined in the OperationalStatus class for the values of this attribute.
min_liquid_capacity Optional[int]

The minimum liquid capacity, in cubic meters, the vessel should be able to hold.
max_liquid_capacity Optional[int]

The maximum liquid capacity, in cubic meters, the vessel should be able to hold.
fixture_types Optional[List[str]]

Return vessels with the specified fixture types. Use constants defined in the FixtureType class for the values of this attribute.
last_cargo_types Optional[List[str]]

Return vessels with the specified last cargo type IDs.
past_port_visits Optional[List[int]]

Return vessels with the specified past port visits.
open_port_ids Optional[List[int]]

Return vessels with the specified open port ids.
canakkale_cancelling Optional[date]

Return vessels with the specified Canakkale cancelling date.
open_date Optional[date]
