An enormous pipe measuring over two miles long is due to arrive off the coast of Blackpool.
It'll be installed in a huge trench under the sea to divert floodwater away, protecting homes and beaches.
It's part of a 200 million pound scheme by United Utilities to improve bathing waters.
Here are some supersize facts about the supersize pipe:
3.7km (2 miles) long and 2.5 metres (more than 8 foot) in diameter
20,000 tonnes in weight
Carries 580 concrete collars like giant cable clips which will hold the pipe down on the seabed when installed
100 people involved in transportation and installation
Fitted with radar collars and GPS tracking to make it visible to other shipping
