Dear SNAME Member,
We are pleased to invite you to attend our second technical meeting for the 2012-2013 season, during which Mr. Jussi Pyörre, Vice President of Technology and Co-founder at ENIRAM Ltd., Finland will speak on the subject of:
“Challenges in Vessel Speed Optimization”
Speed optimization schemes face challenges in daily vessel operations due to very strict constraints imposed by itinerary and due to limited accuracy of available weather and sea current forecasts. Since fuel-optimal routing is highly sensitive to constraints such as just-in-time arrival, one high-speed leg can wipe out the accumulated savings of an entire voyage. We present an approach to optimal speed estimation which is based on statistical route forecasts based on historical data measured on specific routes. The optimization scheme includes penalties for specific unwanted operations, such as excessive acceleration, and rewards for required actions, such as consistent speed control. Simulation is used to provide alternative and improved energy efficient speed profiles. The results from this initial study are based on analysis of operational data collected from twenty vessels, modeling of environmental effects and simulation of optimal speed profiles, which suggest possible 3 ± 1 % energy savings.
Date and location for our meeting are:
Date : Thursday, October 18th, 2012
Time : 7.00 pm
Location : The auditorium of Maran Tankers Inc. (ex Kristen Navigation).
354 Syngrou Ave. (building before the Onassion Hospital)

After the meeting hors d’oeuvres, wine, soft drinks, etc. will be served.
The participation fee is 5 euros for members and students and 10 euros for non-members, which will be paid at the entrance prior to the start of the meeting.
We hope to see you on October 18th!
Very truly yours,
