HELIDECK FOAM SYSTEMS DESIGN
A key
aspect in the successful design for providing an efficient, integrated helideck rescue and fire fighting facility is a complete understanding of the circumstances in which it may be expected to
operate. Flare Fire Safety Engineering specialise in the design of Helideck Foam Systems in accordance with CAP437 and other guidance available in HSE Offshore Helideck Design
Guidelines.
The objectives of a Helideck Foam System, taken from HSE Offshore Helideck Design Guidelines,
should be considered when developing fire fighting facilities and are summarised as follows: "The prevention of life and rescue of helicopter occupants in a fire or crash situation; The containment
and extinguishment of the fire within the crash area; The minimisation of exposure of helideck crews to fire and crash effects; The minimisation of minor incidents to prevent
escalation."
Delivery of Firewater / Foam to a helideck is typically via a Fixed Monitor System (FMS) or
Deck Integrated Fire Fighting System (DIFFS).
Flare Fire Safety Engineering design Helideck Foam Systems using PipeFlow and 3D modelling
software to ensure the systems are hydraulically balanced and meet the Total Water Application Rate and Minimum Operational Foam Stock based on the installation's helideck D-Value.
Following the installation of a Helideck Foam System, our Engineers commission the system in
accordance with the testing recommended by HSE Offshore Information Sheet 6/2011 and CAP437 recommendations.
Upon completion of the successful system commissioning and handover, System Piping Layout
Drawings, Hydraulic Calculation Reports, Opertational Test Procedures, Opertational Test Result Sheets are supplied as a comprehensive reporting package.
