In November 2024, the Northern Endeavour’s floating offtake hose was disconnected from the FPSO for disposal. The Skandi Emerald towed the hose from the FPSO to Darwin where it was pulled out of the water onto a dock.
All of the fluids inside the hose were pumped out and sent to an appropriate onshore facility for disposal. The hose is now being shredded for disposal.

A floating offtake hose is a flexible pipeline that connects 2 vessels to transfer fluid. Connected to the back of the FPSO, the floating offtake hose connected to oil tankers, enabling transfer of crude oil produced and stored on the FPSO.
The Northern Endeavour’s offtake hose was just over 40 cm in diameter and about 300 m long. The hose itself was a string of individual sections, each about 10 m long.

At its maximum flow rate, the offtake hose could transfer over 5,000 m3 or 5 million litres of oil every hour. That’s about 2 Olympic swimming pools an hour. The average tanker holds about 100,000 m3 or 100 million litres which is about 40 Olympic swimming pools. It would take around 20 hours to fill an average tanker.
