Classification society ABS has released a new guide for liquefied natural gas (LNG) bunkering, which outlines requirements for the design, construction, and survey of carriers and barges fitted with dedicated LNG transfer arrangements and intended for regular LNG bunkering service. In parallel ABS has also released its GUIDE FOR LNG BUNKERING. Both documents are available to download further below.
The guide also addresses bunkering station safety, lifting and hose handling equipment, control, monitoring and Emergency Shutdown (ESD) and release safety systems.
While application of the guide is optional, the guide must be followed in order to obtain ABS' optional LNG Bunkering notation.
"Most LNG-fuelled vessels in operation at the time of issuance of this Guide receive LNG bunkers on a relatively small scale, typically through a shore-to-ship basis by road tankers or dedicated shore side LNG tanks," notes ABS.“
It is envisaged that greater LNG transfer rates than those typically used for refueling the current gas fueled ship fleet will be required.
In order to support the further growth and development of LNG fuelled vessels for short sea and international trade, ABS says more dedicated LNG infrastructure is needed, particularly in terms of small scale LNG storage and distribution centres together and dedicated LNG bunkering vessels for ship to ship LNG transfer operations.
"It is envisaged that greater LNG transfer rates than those typically used for refuelling the current gas fuelled ship fleet will be required and this will necessitate the deployment of new and additional bunkering equipment and operational practices," explains ABS.
The guide is noted to be effective from January 1, 2017.
