The course attendees included senior and technical personnel from the Singapore government, gas industry, fuel suppliers, vehicle repair and cylinder testing industry.

SPRING Singapore, 2003

SPRING is the Standards, Productivity and Innovation Board of Singapore. The project entailed the preparation of the complete set of CNG vehicle and refuelling station standards for Singapore, culminating in a one-day seminar in Singapore and the publication of Singapore Technical References TR 10 (CNG vehicle workshop and personnel), TR 11 (CNG vehicle components and installation) and TR 12 (CNG refuelling stations).

Macau Office for the Development of the Energy Sector (GDSE Macau), 2007

A one-week comprehensive CNG training course delivered to GDSE in Macau. The topics included:

• vehicle, cylinder and refuelling technology
• economics
• standards and regulations
• environmental issues.

The attendees included a wide cross section of Macau's government and transport industry officials.

Mercedes-Benz Buses & Coaches (formerly DaimlerChrysler), 2007

Certification of new Mercedes-Benz CNG bus model for the Australian city bus market. The standard for certification was AS 2739. This project was performed in cooperation with Sydney Institute of Technology - Automotive Technology section.

SprintGas, 2008

• Review of the design of an automated, electronically controlled pressure vessel leak testing system. CFS International provided advice on the technical feasibility of the system design provided by SprintGas
• Technical review of the technical compliance of an LPG vehicle conversion system using liquid fuel injection

Four-month comprehensive Bangladesh CNG training course, 2009

This long, detailed training course was produced and delivered for Sydney Institute of Technology. Some 24 topics were taught to four groups of attendees representing the Bangladesh Ministry of Planning, Petrobangla and Rupantarita Prakritik Gas Company. This training program emphasised safety, which has been a major concern of the CNG industry worldwide for many years. (One group learnt vehicle conversion procedures at the Institute's vehicle conversion laboratory).

Thanks to the availability of training time, the attendees were given several CNG site visits, large amounts of review exercises, both independent and supervised, which included internet research and project financial analysis spreadsheets.

CFS International performed as subcontractor to Sydney Institute of Technology, which in turn was contracted to TTT (Training and Technology Transfer) Global of New Zealand.

PTT Exploration & Production (PTTEP), Thailand, 2007-2008

Tender specification and evaluation for:

• LNG plants (50 tpd and 100 tpd)
• LNG vehicle refuelling stations
• LCNG vehicle refuelling stations.

This consulting project was performed in cooperation with the prime contractors, Gas Advisers, an international LNG and cryogenic consultancy firm.

State Transit Authority, Sydney Buses, 2003, 2006 and 2007

• Determination of the safety of defective new onboard composite cylinders for STA CNG buses
• Determination of the safety of onboard composite cylinders which suffered replacement delays at the end of their official service life
• Cost and technical issues of an end-of-service life composite cylinder replacement program for 100 buses.

Transperth (City bus fleet in Perth, Western Australia), 2001, 2007

• Investigation into the fire and destruction of a CNG bus in Perth � The work was commissioned by Transperth, the bus asset owner. The cause was determined quickly and the report completed within two weeks
• Safety screening study for all operations associated with CNG buses
• Safety audit of all Perth CNG bus workshops.

Blue Energy, 2010

Prefeasibility study of the introduction of CNG and LNG into the Australian market. This study was successfully completed, leading to moves by Blue Energy to invest in the natural gas vehicle fuel supply business in Australia.

Brisbane Transport (or "BT", the Brisbane City, Queensland, bus fleet operator, Australia), 2009 and 2010

This project was performed under a subcontract to GHD, an international consulting firm. In the wake of the first Australian CNG cylinder failure/explosion (involving a full composite cylinder on an OEM CNG bus during refuelling) in 2008, the project was to provide risk assessment of the entire spectrum of Brisbane Transport's CNG bus operations, including:

• Safety in the refuelling areas
• CNG bus building workshop
• CNG bus servicing workshops
• Safety of CNG bus against fire and cylinder failure in fire
• Brisbane City underground bus terminal.

Subsequent to the study, CFS provided consulting advice to Brisbane Transport on bus pressure regulator failures and a risk assessment of the time delay introduced to the onboard battery master shut off switch during bus refuelling.

A subsequent major BT engagement was the production of training packages for fast CNG bus refuelling and CNG bus fuel decanting.

South Australian Department of Transport, Energy and Infrastructure (DTEI), 2010

Adelaide is the capital city of the state of South Australia. It has one of the largest CNG city bus fleets in Australia. The DTEI is the owner, and Torrens Transit the operator of the CNG buses and bus workshops. DTEI wished to review the safety of two CNG bus workshops which have been in operation for nearly two decades.

As with the earlier review projects (described above) at other Australian bus fleets, CFS International's review of the Adelaide bus workshops included a site visit to the workshops, discussion with workshop staff and compared the physical safety provisions (e.g. ventilation, fire protection) with the requirements specified by the Australian gas fuelled vehicle workshop standard, AS 2746.

ANGVA CNG Safety Workshops

In March 2010, Dr Hien Ly conducted for ANGVA the Annual Lecture and Safety Workshop at the CNG-NGV Vietnam Forum 2010, in Ho Chi Minh City. The title of the workshop was "CNG mother daughter system operational safety". Workshop attendees were given a written exercise and were awarded an ANGVA attendance certificate.

In October 2011 CFS co-conducted a one-day CNG cylinder safety workshop at the ANGVA 2011 (biennial) conference in Beijing. The workshop consisted of codes and regulations, cylinder types and construction, and installation and inspection techniques. Attendees were awarded an attendance certificate from CFS, ANGVA and CATARC, the China Automotive Technology Centre.
