Submarine cable installations module

The module for submarine cable installations (CYMCAP/SUBMA) assists in calculating the steady-state temperature and ampacity for cables installed in water, on the seabed, in submarine soil and in J-tubes.

Analyze cable installations in submarine applications

The submarine cable installations module allows users to determine the steady-state temperature and ampacity for cables in water, on the seabed, and in silt. It also helps engineers determine steady state temperature and ampacity for cables installed in J-tubes.

More precisely, this add-on module supports modeling of the J-tube section (filled with air portion) above the sea level. This section represents the thermal bottleneck inside the J-tube, which is often considered the most common limiting section in submarine cable installations.

Highlighted features for cables in water, on the seabed or in the silt:

Supports most of the cable configurations, including multiple conductors per phase, multiple dissimilar cables in the same environment
Compatible with DC cables
Smooth transition from multiple casing installation MCAS to submarine installation

Highlighted features for cables in j-tubes:

Radiation and convection inside and outside of the tube are considered in the calculation
Single-core or three-core cables, as well as selected single-phase multiple conductors per phase configurations, are supported
Compatible with DC and AC cables
