The Portuguese Minister of National Defence, José Alberto Azeredo Lopes, has authorised the Portuguese Navy undertake the contracting of services for the first mid-term upgrade of the two TRIDENTE-class submarines.

This upgrade is expected in the life cycle maintenance programme for submarines and may not exceed the total amount of €47.99 million, with the funds to be used come from the Military Programming Law.

The submarines entered Portuguese Navy service in 2010, and now need the first mid-term upgrade, which is essential to maintain operational availability. Upgrades will be conducted in phases and with specific contracts for each submarine, in order to ensure better monitoring and supervision of technical processes, as well as better monitoring of compliance with contractual obligations.

Maintenance actions on the NRP TRIDENTE will be carried out between 2016 and 2018, at a total maximum cost of €23.99 million, while that of the NRP HARPOON will take place between 2018 and 2020 at maximum cost of €24 million, as set out in the Military Programming Law.

The construction company of submarines, thyssenkrupp Marine Systems (TKMS) holds the exclusive knowledge of certain technological areas of subsea 209PN type, currently is the only authority empowered and able to carry out all necessary maintenance work, so the procedure applicable in this case is the negotiation without publishing public announcement.

TKMS and the Alfeite shipyards are developing a joint programme, whose main objective is to enable the Portuguese company to develop its repair and maintenance capabilities for the Type 209N submarine.

Given the performance to date, it is anticipated that this cooperation will lead Alfeite shipyards to participate in the first mid-term upgrade of the NRP TRIDENT between 2016 and 2018, so that the mid-term upgrade of the NRP HARPOON, to be conducted from 2018, will be carried out in-country, by the Alfeite shipyards.
