Different types of transportations are generally available in the tool: Crew transfer vessels, service operation vessels, heavy lift vessels, cable installation vessels, helicopters, and towing vessels. The following tabs show how you can add and set up various specifications for the different vessels. How to create a new vessel with special specifications in the Input library, go to Add a new vessel. After having created the specifications, you have the types of transportations available to use in building a case:
- Adding and editing a Crew transfer vessel (CTV)
- Adding and editing a Service operation vessel (SOV)
- Adding and editing a Heavy lift vessel (HLV)
- Adding and editing a Helicopter (Heli)
- Adding and editing a Towing vessel (Tug)
- Adding and editing a Cable installation vessel (CIV)
- Adding and editing a Crane
- Adding and editing a Feeder vessel
- Adding and editing an Anchor handling vessel (AHV)
- Adding and editing a Component transfer vessel (CoTV)
- Towing vessel cycle processes
In the weather criteria, there is the possibility to define different values for each transport.
The assets access limitations could be the significant wave height. The weather access limits to the assets will be the constraints that will allow a vessel's performance (e.g. a CTV will go offshore only if the weather allows it in the access restrictions).
Tide restrictions affect the bases and ports which is using LAT (Lowest Astronomical Tide). A tide restriction in the port assures the way out to sea and back and a vessel will only be available to head offshore if the tide restriction in the Port assures the way out to sea and back.
Only the wave height transit limitations and the tide restriction are both considered in the vessels weather criteria, any other weather parameter will not affect the vessels performance in transit.

LAT is a standardized reference size that measures the depth of water worldwide. It also defines the coastal line in sea charts. Check this source for more information LAT definition.
