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.
