In case of flammable or toxic process media, venting to atmosphere is not allowed. 8.11.8 Pressure Safety Valves, Rupture Discs Safety relief valves shall be of conventional direct-acting angle pattern, spring loaded, pilot operated and high-capacity type: • Conventional spring-loaded safety valves shall be used in services where there is no backpressure or where the constant backpressure does not exceed 10% of the set pressure. • Balanced bellows safety valves shall be used for variable backpressures or for backpressures ranging from 10% to 50% of the set pressure or when the fluid is corrosive, toxic or fouling. • Pilot operated valves shall be considered on services such as light gases at high set pressure, on clean gas in pulsating service, when the set point is less than 10% above the operating pressure or for very high capacities. For conventional valves, the built-up backpressure shall not exceed 10% of the set pressure. Test gags (sometimes known as transportation gags) shall not be used. Bonnets and top plates for flanged pressure relief valves above NPS 1 inch shall be a bolted design with fully retained gaskets. Screwed bonnets and union bonnets are not permitted. Sizes shall be identified in accordance with API STD 526 showing inlet size - orifice area - outlet size (e.g. 1D2, 2H3...). Flanged PRVs shall meet the requirements of API STD 526, with the following additions: Bonnets and top plates shall be the same material, or equivalent forged material, as the valve body. Each safety relief valve shall be provided with a permanently engraved AISI 316L stainless steel nameplate. Relief valves bodies shall be marked in accordance with ASME B16.34. Basic requirements for inspection and maintenance of pressure relief devices shall comply with API RP 576.

All cabinets shall be lockable for Cyber Security reasons. IS terminals and wire ducts shall be clearly identifiable as IS, preferably blue. 8.11.11 Instrumented Package The package instrumentation, control systems and any associated components (switches, routers, etc.) which are subject to marine classification – typically within the hull and living quarters – shall be type approved by the project selected Classification Society. Instruments which are part of a Safety Instrumented Function shall be certified minimum suitable for SIL 2 applications. The SIL requirement shall apply to all parts of logic solver including controller, system software, I/O modules and FTA’s, relays, etc. The recommendations of IEC 61511 shall be followed. Dedicated sensors and final elements shall be used for safety and control functions in order to avoid common-mode failures. In a similar manner, any on-skid valve (e.g. BDV) which requires a safety actuation by the plant SIS shall be equipped with a dedicated solenoid valve directly hardwired to PSS, ESD system or FGS. The license of the application software shall be embedded in the installed program; the use of USB sticks containing the license and the like are not permitted as all USB ports are disabled for cyber security reasons and are also a potential cause of failure for automatic restart after power failure (i.e. the required auto restart during black start without the requirement for human intervention). By default, the ICSS shall be the clock master for time synchronization of package UCPs. The package Supplier shall provide and install the necessary hardware and/or input point to receive the time synchronization signal from ICSS. All safety executive actions between the package UCP and PSS, FGS and ESD system shall be hardwired. Communication links between UCP and the PCS shall use dedicated communication cards installed in the package PLC rack and in the PCS rack. This communication link shall be based on non-routable communication cards. By default, ModBus TCP/IP (maximum 2 packages per communication card). Packages are normally operated in "remote" mode from the ICSS Operator workstations in the CCR, but the package shall always be capable to run in "local" mode using the UCP's HMI.

All packages shall allow transfer of package data to the Process Data Server (PDS) unless project specifications define that for some specific non-critical systems, such data transfer is not required. Non transfer of data from a package to a PDS shall be subject to COMPANY approval. Base case is to transfer data to the PDS though a PDS interface node. PDS communication links with packages shall not require redundancy unless: • The data storage and data availability of a particular package has been defined as critical. In this case, redundancy is required for the interface nodes as well. • The PDS interface node itself is redundant. Aspentech InMation Integrator shall be installed by COMPANY to provide unified data structure collecting real time and historical data from P3 packages. PDS data acquisition node (PI Data Collector) shall be designed to receive data from the P3 Packages interfaced with PI–OPC interfaces on DMZ Layer 3.5. In addition, InMation Integration Interface shall be provided for the Packages’ data using OPC server. The OPC Server shall be capable of handling up to 240K data points from the ICSS and 500K data point from the Package UCPs, in addition to PI data communication. The communication protocol shall be OPC-UA, which shall also be the preferred protocol for the PDS data link. 8.11.12 Safety Integrity Level The IEC 62061 or IEC 61511 methodology and requirements shall be used to assign the SIL, enabling the appropriate design of the package. SIL verification calculations shall then be carried out for all safety instrumented functions (SIF). 8.11.13 ICSS Functional analysis and standard functions The Package Functional Analysis documents shall be developed by the P3 Package Equipment Vendor to describe with all relevant data and information the detailed functionalities of a specific P3 package. The Package Functional Analysis shall primarily be used for configuring the package UCP. For P1 and P2 packages, supplier shall provide control narratives for their equipment. These shall be part of input documents for the plant Functional Analysis to be used by the Functional Analysis Subcontractor. The Package SUPPLIER shall provide a comprehensive Functional Analysis and description of the package. This shall express in detail all the controls, sequential phases, alarms, events and any additional information implemented in the package PLC. 8.11.14 Cyber Security Refer to NA-101-20-F002-474107 “FPSO Specification – Cyber Security Requirements for System and Packages” [6]. Industrial Information System (SII) shall have cyber security protection methods integrated into the design from the start and not just an “add-on” when the equipment is delivered. Any system determined not to be part of the Industrial Information System domain shall automatically be part of the Enterprise Information System domain (SIE).

Systems defined as SP1 shall not communicate with any other SII system with different security profile except via hardwired signals. Systems defined as SP2 and SP3 may communicate together via a dedicated interface network using non- routable communication cards. The use of IT equipment (i.e. servers, routers, switches, standard firewalls) in place of communications cards is not permitted. (A non-routable interface is an interface that cannot be accessed from another network (e.g. IP, MAC layer). A non-routable interface is typically based on point-to- point communication that use Vendor supported communication cards either Serial or TCP/IP or Ethernet). Systems defined as SP3 shall have their own dedicated Engineering Workstation (EWS). It shall not be possible to configure an SP3 system from any other system. SII equipment shall use non-routable on internet IP address ranges as per RFC 1918. Commercial Off-The-Shelf Software including the Operating System (OS) of any equipment shall be properly configured to minimize cyber risks by disabling all services not used. Any hardware and software not required shall be disabled, includes at a minimum, Email, office applications, games, Bluetooth, wireless communications, etc. 8.11.15 Obsolescence Facilities are designed with an expected design life in the order of 30 years. It is not practical to achieve such a design life for electronic based equipment without the requirement for upgrading (revamping). The control and instrumentation equipment scope shall be given specific attention to ensure all control and safety systems, components, software and individual elements can be maintained or replaced such that the original function and integrity of the whole production system can continue in an uninterrupted manner for the field life. A project specific Obsolescence Management Plan shall be developed. It shall address all obsolescence requirements and data. The Obsolescence Management Plan shall consider the complete life cycle including: • Design phase • Project delivery phase • Operation & maintenance phase The Obsolescence Management Plan shall be further complemented during the detailed engineering stage by ICSS and Package Vendors and shall detail all aspects of equipment life cycle. Obsolescence database shall be part of OMP and required from Contractor/ ICSS Vendor from CFT stage up to commissioning stage. 8.12 Hazardous Material Inventory of Hazardous Material (IHM) shall be maintained as per Hong-Kong Ship Recycling Convention (2009). Company is requesting to include the two additional materials listed in EU-SRR type IHM to anticipate further update of Hong Kong Convention: 1 Perfluoro octane sulfonic acid (PFOS) (As defined in EU-SRR Annex I: “perfluorooctane sulfonic acid” (PFOS) means perfluorooctane sulfonic acid and its derivatives) and, 2 Brominated Flame Retardant (HBCDD) (Refer to EU-SRR Annex II) This document is the property of TotalEnergies.
