STAGE 1

CONNECTING TUG

Anchor state: Dropped (Hooked).

• OrcaFlex will use the Preset Mooring Line object to calculate a catenary wire between tug and anchor.
  The Work Wire Length observation will be used for the length of the first section for the preset mooring line object.

STAGE 2

CONNECTING RIG

Anchor state: Dropped (Hooked).

• OrcaFlex will use the Preset Mooring Line object to calculate a catenary wire between tug and anchor.
  The Work Wire Length observation will be used for the length of the first section for the preset mooring line object.
  
  
• OrcaFlex will use the Rig Chain Line object to calculate a catenary wire between rig and tug.
  The Rig Chain Length observation will be used for the total length (all sections) for the rig chain line object.

STAGE 3

DEPLOY

Anchor state: Dropped (Deployed).

• OrcaFlex will use the Anchor Deploy Line object to calculate a catenary wire between rig and anchor.
  The Rig Chain Length observation will be used for the length of the first section for the anchor deploy line object.
  
  
• OrcaFlex will use the Work Wire Link object to calculate a wire between tug and the Anchor Deployed Line.
  The Work Wire Length observation will be used for the unstretched length for the work wire link object.

STAGE 4
