LNG as marine fuel – where technology meets logistics

Abstract

Following the establishment of the ‘LNG Marine Fuel Institute’ in Australia and research projects on alternative fuelling of ore carriers operating out of Australia, the focus of the marine and oil and gas industry is turning increasingly towards the adoption of liquefied natural gas (LNG) as a fuel oil. The development of LNG bunkering facilities on Australian soil followed. For LNG to be a viable option for deep sea shipping, it is all about infrastructure, technology and the human element. Thus far, LNG as fuel oil was only applied on LNG carriers; outside of that, LNG has mainly been used for short sea applications, which are tightly controlled from a technical and human element perspective mainly through shore-to-ship custody transfer. For deep sea shipping however, the infrastructure needs to be in place to allow regular refuelling options on various global shipping trade routes. It is anticipated that for deep sea shipping, the main mode of LNG fuelling will be through ship-to-ship custody transfers with required risk management. LNG bunkering technology standards and procedures are largely maturing, and efforts are underway to harmonise these standards globally to allow for flexible fuelling locations for ships traversing large distances. The remaining challenge will be to enhance a ship’s crew competence. The level of sophistication required of a crew for LNG bunkering is not something attained thus far in conventional oil bunkering and needs to be addressed. Continuous Competence Management Systems taking LNG cargo trading vessel experience into account, together with the ‘Standards of Training Certification and Watchkeeping for Seafarers’ requirements, is vital for the safe development of gas bunkering for deep sea shipping.
