8 RISK ASSESSMENT

8.1 AREA CLASSIFICATION. Module P2 will be located in Restricted Area. As such all electrical equipment and instruments installed outside, shall be suitable for Zone 1, Gas group IIA, Temperature Class T3.

Hydrocarbon gas detectors (3 off, 2oo3 voting, for each intake) shall be required at all fresh air intakes to activate the FGS in case of gas release from the process area etc. The FGS will then in turn close the gas tight dampers located on the fresh air ductwork so as not to impact on the Topside internal classification (safe area).

The air pressure in the room spaces of the Topside module P2 shall be maintained by means of pressure relief dampers (refer to block diagrams) and will be kept in a slight but continuous positive overpressure with respect to outside : as such they are considered as safe area.

The exception is the Battery Room, which shall be classified Zone 1 due to the potential presence of Hydrogen. This room shall be of a slightly lower pressure relative to the other Topside P2 Module Rooms while higher than atmosphere.

A 3m zone 2 hazardous area is generated by doors and exhaust of the laboratory. Laboratory shall be then ventilated and classified zone 2.

Electrical Equipment inside this room shall comply with Zone 1, Group IIC and Temperature Class T3 requirements (IEC 60079 requirements).

8.2 FIRE RISK ASSESSMENT FOR EXTERNAL BULKHEADS AND DECKS

The presence of electrical and instrumentation switchboards and batteries originates a fire risk from inside the Module P2.

All HVAC penetrations of classified bulkheads and decks shall be of the same standard as that of the bulkhead/wall/deck/floor, including fire certified spools.

11 ARCHITECTURAL REQUIREMENTS

11.1 INSULATION – PASSIVE FIRE PROTECTION Marine approved mineral shall be installed in the form of semi-rigid slabs, coupled with reinforced aluminium foils as vapour barrier.

The insulation shall be designed to fulfil at the same time the following goals : passive fireproofing, thermal insulation, acoustic insulation. Thickness and density shall match with the above requirements, whichever is the more stringent.

The mineral panels shall be installed adherent to the steel plates and beams, supported by pins welded to the structure and fastened by washers.

Thermal Insulation.

The following minimum thermal insulation shall be achieved (U-value):

External walls, roof, floors 0.60 W / (m2 °K)

Doors 3.50 W / (m2 °K)

Windows 2.70 W / (m2 °K)

All HVAC calculations are to be based on these values or manufacturer standard if more efficient.

Passive fire protection:

External fire-proofing shall be provided with intumescent painting. Internal fire-proofing for bulkheads and decks (including supporting steel beams) shall be provided through rockwool insulation ; internal steel columns shall be protected where necessary to insure the stability.

Both systems shall be compliant with the fire risk assessments (see section 8.2).

11.2 INTERIOR WALL SYSTEM Any system shall be complied with IMO regulations for non-combustibility and fire-resistance.

The fire class definition of the accommodation partitioning will be in accordance with the SOLAS rules.

All B15 partition shall be high noise- reduction type panel (50 mm minimum thickness).

All floor areas shall receive epoxy resin flooring except rooms where raised floors are required.

All wet areas shall have epoxy rolled base. All dry areas shall have a 101.6mm (4”) cove base. As a general rule, the smoother and less porous a surface, the easier it is to clean. However, for wet purpose applications, the surface must be textured. Such texturing can be achieved by selective grading of aggregates, or by sandwiching special high abrasion resistant aggregate between the surface coatings of clear or pigmented resins. The degree of contaminant build-up on the floor will be dictated by the coarseness.

Epoxy resin floors shall be designed for heavy duty, extreme durability and easy maintenance. The surface shall be anti-slip type.
