Key Platform Vocabulary
A heavy object placed on or in the seafloor to hold mooring lines in place.Essential for safety and stability
Anchor
Moving up and down
Heave
Floating structure that stays in place with long cables,called tethers that are pulled tight between the platform and the anchor on the seafloor
Tension Leg Platforms
Gradual wearing away of metal due to contact with seawater and oxygen
Corrosion
