Activity Types
There are many different forms of maritime activity. As
each activity has its own associated patterns and behaviours,
it is necessary to simulate each activity’s traffic
separately. For instance, large commercial shipping vessels
(such as a tanker, bulk, or cargo ship) behave very differently
than smaller vessels (such as a kayak, work boat, or fishing
vessel), and should therefore be modeled differently. |

Differences between activity groups include
aspects such as:
- Routes:
Transatlantic shipping, lobster fishers, and sea kayakers
ply dramatically different waters.
- Risks: Risk is proportional
to both the likelihood of an incident
occurring and the severity of the incident
(Risk Modeling).
Risks vary significantly across activity groups. Some activity
types may be considered ‘risky’ because they have
a higher probability of an accident occurring, whereas others
may be ‘risky’ because they have a lower probability
of incident
but the consequences of an incident
are higher. Consequences include negative impacts on people,
property, and/or the environment.
At MARIN, these various activity types have been
broken down into several groups and their traffic modeled separately
with the appropriate consideration for land
avoidance, route selection, and behavioural patterns.
These groups include:
