IEC 61511 SIL-2 / SIL-3 fire & gas controllers.
F&G logic-solvers and ESD controllers integrated to plant DCS — with full SIL verification, FMEDA evidence, FAT and class-society survey support. IEC 61508 / 61511.
Functional safety, traceable
A SIL-rated F&G controller is more than a PLC — it is a documented functional-safety chain from sensor through logic-solver to final element. Hawk Marine builds the cause-and-effect, runs the FMEDA, supports SIL verification and produces the documentation pack auditors expect.
SIL-2 and SIL-3 capable
Triple-modular-redundant logic-solvers for SIL-3 demand mode F&G and ESD.
Cause & effect matrix
Documented C&E from HAZOP through to logic-solver implementation.
DCS integration
Modbus, OPC-UA, hard-wired interface to Honeywell, Yokogawa, ABB DCS.
