Blue H Engineering’s key innovation is the “self installing TLP”, which includes: the method of towing out and mooring the unit in “one go” i.e. without needing lifting and installation vessels; the method how to install and adjust tether lengths for non flat sea beds; having different depth possibilities per leg; the use of submergible gravity anchors, etc, all of which combined are just some of the key innovations bringing the CAPEX down to attractive levels.
