DESCRIPTION:Hycean worlds\, characterised by their deep H2O oceans beneath
  H2-rich atmospheres\, provide exciting new candidates for habitability am
 ongst the exoplanet population. With their larger radii and atmospheric sc
 ale heights relative to terrestrial planets\, Hycean worlds are promising 
 candidates for atmospheric characterisation and biomarker detection. Inter
 nal structure modelling plays an important role in the characterisation of
  exoplanets based on their bulk properties\, however degeneracies between 
 possible interior compositions make this challenging.  Atmospheric data\, 
 for instance with upcoming JWST observations\, can help in breaking these 
 degeneracies. We present our new internal structure model and discuss an a
 pplication of the model to a candidate Hycean planet with recent atmospher
 ic data. The possible compositions\, surface conditions and ocean depths a
 re investigated\, and limits are placed on the conditions for habitability
  on this planet.
