Transit top up

With offshore maintenance costs soaring, Dutch firm Beele Engineering is anticipating keen interest in its ‘Rise’ extender frame which can be retrofitted onto cable and pipe transits on ships and platforms.


The system, which can be used for all A0-A60 multi-cable transits, assists in the upgrading of existing conventional conduit systems to provide firesafe and gas and smoke tight sealing of cable conduits. The extender frame not only makes it easier to remove or add cables and thus reduce maintenance costs, but also instantly doubles the usable space inside any block system transit frame, says Beele, adding that the Rise system also obviates the need for extra insulation at the front of the penetration and/or in between the cables. The frame can be installed without the need to remove any existing cables.

The frame consists of two metal plate sections, the flanges of which are inserted into the existing conduit. The length of the flanges corresponds to the length of conventional conduit frames. The two sections are then joined together into a single unit by means of nuts and bolts. For optimised stability, Beele suggests spot-welding the extension frame to the existing conduit.
