Visible Weed and Foam Infestation on Gas Rigs

The foam and weed covering the gas rigs are the visible manifestations of the sentient seaweed’s spread, serving as undeniable proof of the threat’s existence and urgency. Harris cites the helicopter pilot’s report of the infestation to back his demands, while Jones’ initial skepticism ('It's so fantastic') is undermined by the evidence. The objects symbolize the existential danger: a creeping, unstoppable force that has already claimed lives (e.g., Van Lutyens) and now threatens the entire refinery. Their presence looms over the debate, making the stakes tangible and immediate.
