I believe that the 29 design requirements the Honourable Member refers to are the differences between the Batch 2 Offshore Patrol Vessels (OPVs) and those delivered to the Brazilian Navy, which were not the same design as the initial Batch. The new requirements were:

1 Watertight Integrity Modifications
2 Fire Safety Modifications
3 Enhanced firefighting facilities
4 Automatic Emergency Lights
5 Flight Deck Officer Position
6 Domestic refrigeration Modifications
7 Sewage Treatment Plant Modifications
8 Exhaust System Modifications – (No longer required)
9 Ballast Water Modifications
10 Merlin helicopter operation
11 Helicopter In-Flight Refuelling
12 Helicopter refuelling modifications
13 Changes to ship’s minimum operating temperature
14 Davit Modifications
15 Force Protection Weapon Modifications
16 Install WECDIS/WAIS
17 Install Combat Management System
18 Military communications modifications
19 Magazine Protection
20 Radio Equipment Room Modifications
21 Change lighting and domestic power voltage from 115v to 230v
22 Codification of equipment
23 Provision of life saving equipment
24 Replace navigation radars
25 Install Military GPS
26 Install flight deck landing grid
27 Fuel efficiency monitoring
28 Provide emergency communication equipment
29 Machinery Space Walkway

The manned aircraft able to use the Royal Navy’s new OPVs are Merlin and Wildcat helicopters. There are no current plans for the operation of unmanned vehicles from these vessels.
