Support Multiple Reference-Point Combinations

Qastor 2.5 in Tandem Mooring Mode only displays a single connection line showing bearing and distance from the stern of the primary vessel to the bow of the secondary vessel. For FPSOs that offload over the bow, operators cannot switch the reference points, making situational awareness and alignment checks more challenging.

In the new version, it supports displaying the bearing and distance between an FPSO and other vessels using multiple reference-point combinations beyond the fixed stern-to-bow view. Operators can choose combinations such as bow-to-bow, stern-to-stern, or side-by-side.

Enhanced the distance Vessels (FPSO) alarm

The “Distance Vessels (FPSO)” alarm behavior has been corrected to use consistent distance references and clearer threshold logic.
