Putting Safety First

Safety – freedom from danger and risk of injury ­– is the prime concern with cable and pipe transits. When a hole is cut in a deck, bulkhead, wall or floor to allow the passage of cables or pipes, risk is introduced into the structure, particularly with regard to the spaces left between the cables and/or pipes after they have been installed. If a fire should occur in a switch room or an engine room, for example, decks and bulkheads act as fire barriers that prevent the spread of flames, heat and smoke. This protective function, therefore, must be reinstated and the risk of hazards spreading eliminated by installing gas-tight self-extinguishing packing between cables and pipes passing through decks and bulkheads.

Transits prevent fire, smoke, gas and water from reaching adjacent parts of a structure through cable and pipe penetrations in the event of hazards occurring in a particular compartment.

Playing a vital role

Although cable and pipe transits may be regarded as minor components of a ship, an offshore oil platform, a power plant or other installation, they play a vital role in protecting people, property and the continuity of operations. Vast sums of money are invested in skilled employees and high-value structures and these indispensable assets must be carefully safeguarded at all times. This is why the omission or poor construction and installation of transits in a structure may be regarded as gross negligence.

MCT Brattberg is well aware of the vital role that cable and pipe transits play. That’s why we are committed to putting safety first.

Cable and pipe transits must have features that make them safe in a variety of hazardous environments to protect people, property – including intellectual property like computer data – and to help ensure the continued operations of a business or other organization.  



The design, materials, construction and finish of frames play decisive roles in determining the safety of frames in withstanding constant stress in maritime and land-based environments.


Cable management 

Before working with insert blocks, cable management has to be carried out. Basically, this means that all cables passing through frames must have enough movement to allow them to be positioned correctly to facilitate fitting the insert blocks.


Insert blocks 

For first-rate insert blocks, a lot of thought and good science goes into what may at first seem a simple transit component. But the performance of blocks is a key element in assuring the safety of cable transits.


Transit installation 

No matter how many safety features are built into the components of cable and pipe transits, they can only be realized through correct installation. This means that transits must be complemented with training to maximize the safety awareness in all stakeholders.


Testing and Inspection 

Testing for certification purposes is carried out in independent laboratories throughout the world. The Fire Test Procedure (FTP Codes) Standards, however, apply equally to all laboratories, no matter their location.
