Samuel Beckett-class offshore patrol vessel

The Samuel Beckett-class offshore patrol vessel is a class of offshore patrol vessels (OPV) ordered by the Irish Naval Service from October 2010. The first vessel is named LÉ Samuel Beckett (P61), which is also the name given to the class. Construction on this first vessel commenced in November 2011, and it was commissioned in May 2014. The second vessel was named LÉ James Joyce (P62) and delivered in 2015, a third named LÉ William Butler Yeats (P63) and delivered in 2016,  with a fourth vessel ordered in June 2016, and due to be named George Bernard Shaw.

Background and design
Vard Marine Inc. (formerly STX Marine) designed the vessels, which have features in common with an earlier design, the, in service with the Irish Naval Service since 1999.

The 90 m OPV vessels are designated PV90 by Babcock Marine and approximately 10 m longer with an additional 0.6 m in depth to the existing Róisín-class PV80 vessels. This is intended to increase both its capabilities and abilities in the rough waters of the North Atlantic. The PV90 ship is designed carry a crew of 44 and have space for up to 10 trainees. The ships' published cruising speed is 16 kn, with a top speed of 23 kn.

The New Zealand Navy uses an 85 m version of the Vard Marine Inc. OPV design referred to as the. This is a modified version of the older Irish Navy Róisín-class PV80 vessels with helideck and hangar incorporated.

The new ships are designed to carry remotely operated submersibles and a decompression chamber for divers. This is intended to add enhanced capabilities to undertake search and rescue, search and recovery, under sea exploration and increased sea area surveillance. The expanded deck area would also allow the Navy to deploy unmanned surveillance planes for the first time. Features also include Dynamic Positioning systems and "Power Take In Systems" to enable fuel savings as the main engines can be shut down and power sourced from battery storage or a smaller more economical engine.

The first new ship was commissioned on 17 May 2014 - to replace LÉ Emer (P21) which was decommissioned on 20 September 2013.

Planning and construction
In 2007 it was reported that the Defence Forces expected to spend in the region of €180m on a replacement for the three existing vessels of Emer class.

In July 2010 the Irish Minister for Defence, Tony Killeen, announced that the Department of Defence and Naval Service would be entering into talks with UK shipbuilder Babcock Marine on two vessels worth €50m each, with an option for a third.

In October 2010 contracts were signed, and the 'cutting of steel' for the first ship occurred on 24 November 2011.

On 19 May 2012 Irish Naval Service Flag Office Commodore Mark Mellett (subsequently Rear Admiral, DCOS Sp) attended the traditional keel-laying ceremony for the first of the 90 m OPVs. While modular construction methods don't strictly involve keel-laying, the term is still considered an important milestone as it signals the first stage of connecting each of the components together. The keel-laying ceremony took place in Babcock Marine’s Appledore Shipbuilding Yard in Devon, UK.

The delivery of the first of the vessels was set for 2014 with the second in 2015. The fit-out of crew quarters and facilities on the first two 55 berth ships was contracted to Moss Marine of Southampton in a £4.5 million contract. Fitting out of the first ship began in March 2012 for completion in early 2014.

The option on the third vessel was exercised following the commissioning of Samuel Beckett, with delivery scheduled for 2016. Payment for the ships was planned to be extended over a number of years to 2017. The cost of the first three ships, including the main armament, was €213 million. The fourth was costed at €66 million.

Systems
Onboard systems include Mercury IP communication systems from communications and broadcast equipment vendors Trilogy. Each vessel is equipped with two such communications systems. The first uses VHF, UHF and HF marine radio channels on panels installed throughout the vessel. The second system aims to connect users in pre-configured work groups using interfaces installed at work stations around each vessel.

Names
The first ships were named for Samuel Beckett and James Joyce, as disclosed in July 2013 by the Minister for Defence Alan Shatter in Dáil Éireann. This decision to name the ships after literary figures, seen as controversial in some quarters, saw a break from the tradition of naming Irish Naval vessels after women in Irish mythology.
