Abstract
Contemplated hybrid riser towers are configured such that individual riser lines can be added or removed via submarine ROV. Most preferably, riser lines are made from a housing and syntactic foam that encloses a riser pipe to so provide insulation and buoyancy. In further preferred aspects, hybrid riser towers are coupled to each other via a truss to allow expansion via SCR and/or to provide a riser porch.
