The SMIT bracket is designed and specified to withstand the expected breaking load of the chain being used.
OCIMF defines the SMIT bracket as a “fitting for securing the end link of a chafe chain consisting of two parallel vertical plates mounted on a base with a sliding bolt passing through the plates” (OCIMF Mooring Equipment Guidelines MEG4, Fourth Edition 2018).
Risk associated with using SMIT brackets in emergency situations
To release the chafing chain from the SMIT bracket, an operative has to manually drive the securing pin out of the SMIT bracket with a sledgehammer.
When the chafing chain is slack, this may be achieved with a relative degree of safety. However, if the chain is under tension with both vessels pulling from each other then releasing a chain under a 200T tension can pose a serious risk to both personnel and deck infrastructures.
In this circumstance, the amount of energy stored in a chain is enormous and on disconnection, the release of this uncontrolled energy from the chain can result in unpredictable consequences.
In certain offshore operations the SMIT bracket is therefore still considered as a method to quickly disconnect a chain. However, there are risks associated with the use of SMIT brackets in emergency disconnect situations.
Device used to mitigate risk when releasing a chain under tension
The OCIMF has in its 2020 FPSO Heading Control Guidelines, recognized
that the safer alternative to using a hammer to disconnect a chain from
the SMIT bracket is an emergency release device such as the Gall
Thomson Powered Offshore Disconnect (PODx).
The use of PODx does not require crew to stand next to the SMIT bracket during an emergency disconnection process.
PODx is a simple, offshore proven system that allows chain release
under tension. The PODx is made of two simple blocks and a release and
reset bolt activated via a compact HPU.
The HPU enables manual and remote activation of the PODx so that the chain is released in a safe and controlled manner.
PODx provides a range of safe working load specifications from 2.5 Tons to 600Tons.
