NOFIRNO cable transits in fire divisions
1 Scope of the Covenant
Fire safe, water tight and air tight multi-cable transits for application in fire divisions.
For fire resistance the transits comply with the requirements described in:
• International Maritime Organization - IMO Resolution MSC.307(88) – International Code for Application of Fire Test
Procedures, 2010 (FTP Code 2010) – Part 3
• International Convention for the Safety of Life at Sea - Articles of the International Convention for the Safety of Life at
Sea, SOLAS 1974, as amended, SOLAS 2000 Regulations – Chapter II-2 / 9.3.1
For water and air tightness the transits comply with the performance as described in this covenant.
1.1 Description of the product
NOFIRNO sealing system
The NOFIRNO sealing system is for fire safe, water tight and air tight penetrations in decks and bulkheads.
The NOFIRNO sealing system consists of a combination of NOFIRNO rubber filler sleeves, rubber cable sleeves and
NOFIRNO sealant. The aperture between penetrating cables and the inner wall of the transit frame is filled with filler
sleeves and on both sides the transit frame opening is sealed with a sealant. The thickness of the sealant is minimum 15
mm.
For restricted applications NOFIRNO/EMC multi-cable transits can be used, consisting of NOFIRNO cable and filler
sleeves and a 40 mm thick CONDUCTON flexible rubber layer on fire side. There should be used minimum 20 mm
NOFIRNO sealant at both sides.
The filler sleeves are available in six diameter sizes and in five lengths. The cable inserts sleeves are available in 29
diameter sizes and in five lengths.
1.2 Field of application
Fire safe, water tight and air tight sealing of multi-cable transits through decks and bulkheads.
The sealing system is intended to be used for the sealing of blind transits (without cables) and the transits of single or of
multi cables up to 105 mm outer diameter and 3x380 mm2 through penetrations in bulkheads and decks.
The transit frames are welded or bolted to the bulkhead or deck.
The maximum size of the transits frames is 600 x 300 mm or equivalent of 1800 cm2.
The minimum wall thickness of the transit frames is 5 mm.
The minimum length of the transit frames is 160 mm.
For NOFIRNO/EMC multi-cable transits the minimum transit length is 200 mm.
For A-60 bulkhead and deck penetrations the transit frames shall be insulated with approved A-60 insulation.
For A-0 bulkhead and deck penetrations no insulation is required.
The maximum filling rate is 35 %.

2.3 Water and air tightness
Test reports:
• Kiwa Covenant K90720/02 – Water tight and air tight sealing systems for cable transits – chapter 1 and annex C
• Kiwa witness reports WT 1312-127, WT 1404-131, WT 1408-140, WT 1411-142, WT 1412-116, WT 1412-146,
WT 1502-147, WT 1512-172
2.3.1 Water tightness The NOFIRNO sealing system is water tight and resistant to submerged conditions. The general water tightness of
NOFIRNO sealing system for cable transits is certified according to Kiwa Covenant K90720/02.
The water tightness for the specific cable transits within the scope of this Covenant is presented in table 1 and in Annex C.
The maximum allowed hydrostatic pressure depends on the dimensions of the transit opening, the transit frame, the
number and dimensions of the ducted cables and the thickness of the sealant layers. Transits with cables always lead to
higher values of maximum allowed hydrostatic pressure than blank transits of the same dimensions because of smaller
free pressurized transit surfaces.
Table 1. Water tightness
NOFIRNO sealing system water tightness
Blank rectangular transits, transit length ≥ 160 mm For maximum transit dimension 600 x 300 mm:
from 0 to maximum 1,5 bar for 600 x 300 mm
For small transits:
from 0 to maximum 10,2 bar for 70 x 70 mm and smaller *
* outer transit dimensions (5 mm wall thickness)
See Annex C for more detailed information.
Users of the NOFIRNO sealing system shall consult Beele Engineering for the pressure rating for the applicable specific
applications.

2.3.2 Air tightness
The NOFIRNO sealing system is air tight. The general air tightness of NOFIRNO sealing system for cable transits is
certified according to Kiwa Covenant K90720/02.
The air tightness for the specific cable transits within the scope of this Covenant is presented in tables 2 and 3 and in
Annex D.
The maximum allowed static air pressure depends on the dimensions of the transit opening, the transit frame, the number
and dimensions of the ducted cables and the thickness of the sealant layers. Transits with cables always lead to higher
values of maximum allowed static air pressure than blank transits of the same dimensions because of smaller free
pressurized transit surfaces.
Because of the behaviour of flexible sealing products, assessment of the air tightness is necessary for both low pressure
as well as high pressure applications.
