these problems were solved, larger exhaust pipes had to be fixed (originally, exhaust was vented underwater to minimise infra-red signature, but it turned out that the ship was taking water from these openings). After further studies, it became possible to gain the space of one propulsion compartment, which is now used for cargo and personnel. The ships can ferry 20 people, and up to 60 for short travel with a calm sea. Service history In May 2009, La Fougueuse arrived in Brest to be decommissioned, the first of the P400 class to be taken out of service. In February 2011, it was decided that eight P400-class vessels will be equipped with new engines. Previously, these ships were scheduled to retire according to Jane's Navy International. They will repair to ensure renewal of their operation until 2020. Earlier, the French Navy had intended to retire these ships in the period from 2010 to 2014. The reason for extending the service life of ships of this class is the desire to reduce the cost of procurement of new weapons. The ships were initially equipped with two Wartsila SACM UD30 V16 M3 diesel engines. The new engines will be delivered to France's Mother Boda and installed by "Piriu Naval Service" (PNS - Piriou Naval Services) in a 10-year contract worth €30 million (US$39 million). The first of the modernised ships should be returned to the French Navy by March 2011. PNS also undertakes restoration of these ships. One of the decommissioned vessels, La Tapageuse, was offered to the Philippine Coast Guard, and was estimated to cost about €6 million including the refurbishing works. The deal did not push through, and French shipbuilder Piriou took control of the ship, which was later sold to Gabon as part of a larger deal. Replacements In December 2019 six Patrouilleur Outre-mer (POM-type) patrol vessels were ordered as replacements for the P400s as well as for other French coast guard vessels. These were to be delivered between 2022 and 2025 to protect the exclusive economic zone of French overseas territories in the Indian Ocean and the Pacific. In May 2021, it was reported that the delivery of the first of these vessels would be delayed, from an originally planned in-service date of 2022, until 2023.
