Special 3-Day Mini Sessions (0900-1200)

Calculation of demurrage can sometimes be a challenge, especially if you are new to the job or starting to work with some of the newer charter contracts and a one or two-day virtual session may not give you enough time for the key principles to be absorbed. Accordingly, until things are back to ‘normal’ and we can safely provide face-to-face sessions for our clients, Enercon is pleased to offer one of our most popular courses in a new virtual format.  Maintaining the same content--and making a few additions--we have divided the course into sections that each participant can learn, review, ponder, and ask questions about at their own pace.


Enercon has modified its usual 2-day Charter Parties, Laytime and Demurrage course to be presented in 3-hour sessions over 3 days.  Each session will allow the participants to address the topics covered in the classroom and take specific sections home to complete assignments to solidify their knowledge and familiarity of the subjects.  In addition to the three sessions, a fourth session will be offered FREE OF CHARGE – this special 3-hour Q&A session will address the topics detailed in the foregoing sessions that anyone may need further explanation on or who would like some extra class time to review what they learned and may still have questions about.  This additional session will be open to anyone registered for this new course or for anyone who has already attended any of our Charter Parties, Laytime and Demurrage courses this year.  REGISTRATION IS NECESSARY – SIGN UP TODAY!
