"The four contracts, signed over the past year and worth an estimated Euro 10 million in total, will see Tata Steel supply in excess of 55 km of pipe weighing more than 9,000 tonnes," the company said in a statement.
Under the contracts, Tata Steel will supply around 28 km of carrier pipe and 27 km of sleeve pipe. The pipes would be manufactured at the company's Hartlepool pipe mills in the UK.
Tata Steel said to mark the strengthening relations between the two companies, it has also signed a global framework agreement with Subsea 7 which cements and formalises the companies' long-standing partnership, which first began 25 years ago.
