BUNKERS 

The inherently high cost of bunkers generally makes them the highest single daily cost of ship operations. Off-spec bunkers cause most engine problems and off-hire time. This course will address how bunkers are made and properly measured as well as what the exact specs of each type should be as per ISO 8217.  MARPOL VI and IMO 2020 have placed strict environmental requirements on the amount of emissions that may be exhausted into the atmosphere, Maximum sulfur emissions allowed has been reduced from 3% to as low as .1%.  To meet these goals, alternative fuels are being turned to for use on the ships.  The alternate fuels to be discussed and the advantages and disadvantages of each will include LNG, LPG, ammonia, hydrogen, methanol, and others.  In addition, some owners are using scrubbers to meet their emissions goals.

Program Objective: To introduce the participants to the world of bunkers and the fueling of ships.  To show how managing bunkers accurately is an essential piece in controlling ship costs.


Course Format

The sessions consist of a combination of lectures, audio visual presentations, problem solving discussions/calculations, hands-on use of equipment (where applicable), and daily question/answer periods.


Registration begins a half hour before the scheduled start of each session.  Sessions are conducted from 0900 to 1630 daily, except in Singapore where they end at 1700.

Continental breakfast and refreshments are provided during the Houston and Singapore sessions.

Everyone is on their own for lunch, except in Singapore where refreshments and full lunch is provided each day.  


Materials

Participants receive original reference books, pertinent industry publications, papers and other handouts.  A course certificate is awarded to all of those successfully completing the program.

 

Who Should Attend

Manager, field/office staff, traders, brokers, owners, ship/terminal operators, charterers, schedulers, attorneys, claims analysts, accountants, government personnel, and anyone working in the marine petroleum industry in any way will benefit from these programs.

Bring Your Questions...They Will Be Answered!

Enercon's courses have been designed to be as practical as possible and bring these technical subjects into context for participants. This is done, in part, by allowing the attendees to discuss their specific operational problems as well as directly participate in the structured program.  If a specific question raised cannot be answered immediately, all attempts will be made to have an answer before the end of the program.  If this is not possible, the question will be researched and a response provided as soon as practical after the course.
