FIRE RATED WINDOWS – A-0
DNV requires all new supply ships with Fi-Fi class to be equipped with A-0 windows.
This requirement includes the wheelhouse as well as cabins. In order to meet the
general requirements of fire-protection for vessels, the fire-test shall be conducted
from the external side (high risk side). Some of the windows fitted on Offshore supply
ships are approx. two meters high. The windows in front are angled outwards 10-25
degrees and the optical requirements are challenging. Furthermore the windows shall
have sufficient strength to withstand the impact of green sea.
- All tankers
- Passenger ships, ferries and flotels
- Floating production units
- Offshore accommodation and technical modules
- Drilling rigs
- Offshore supply ships with fire-fighting capability
- Blast Wals
FIRE RATED WINDOWS – A-60
According to SOLAs requirements exterior boundaries of superstructures and
deckhouses enclosing accommodations on tank ships facing the cargo area are to
be insulated to A-60 standard, and also for the side portion of the boundaries
3 m back from the front boundary.
FIRE RATED WINDOWS – H-120
H-120 bulkheads are required on offshore installations between production
and accommodation areas, while FPSO and drill ships have requirements for
IMS certified H-120 windows consist of a toughened pressure glass and
a 78 mm fire barrier consisting of layers of float glass and tumescent laminate
and can safely be installed in H-60 /H-120 bulkheads. Due to the superior
optical quality IMS H-120 windows are considered first choice for
BLAST RATED WINDOWS
IMS group AS have developed a Window that will meet most blast requirements that will be found on oil and gas facilities. With our solution it is possible to combine our Fire rated A-0, A-60 and H-120 windows with the blast requirements that will be requested. According to our calculations we can produce and deliver windows with more than 1 bar blast (Size 550mm x 500mm). Since there is no standard blast, we always look at each individual project and give free advice before we decide if it is possible for us to deliver. The initial calculations to see if we can deliver the requested sizes are based on Timoshenko’s formula.
BULLET RESISTANT WINDOWS
IMS group AS can deliver bullet resistant windows and glass that can be fitted to most ships and offshore facilities. The windows can be retrofitted to suite already existing windows or to replace existing windows. With our solution it is possible to combine our Fire rated A-0, A-60 and H-120 windows with the bullet proof windows. The bullet resistance we produce and deliver is BR4 and BR6. We always look at each individual project and give free advice before it is decided if we can deliver or not.
