Story: Engineering on the sea floor

Māui A in position

Māui A in position

To secure the Māui A platform to the seabed, it was floated into an upright position and dropped to the sea floor. Each of the platform’s four feet were pinned to the seabed by seven piles. These were to be driven into the mud and sand to a depth of 73 metres, but a layer of sand at around 25 metres proved difficult to penetrate. The entire anchoring system had to be re-designed, and only 16 of the 28 piles could be driven to the full 73 metres.
