Benefit

iSEMS enable ships to minimize their energy1) consumption.

1) Energy cost = Bunker cost + Time Cost

Traceability

illust img

  • Easy voyage tracking
  • Measure effectiveness of fuel saving techniques
    and devices based on data
  • Utilize the measuring data with weather information
    when be occurred the legal dispute like speed claim
  • Find the influence of factors that affect the
    energy efficiency

Time Save

illust img

  • Easy to handle tasks on energy efficiency
  • Make the position reports easily and quickly on the ship
  • Make the documents in response to environmental regulations quickly and easily

Decision Support

illust img

  • Decide on energy efficiency management while planning and sailing
  • More accurate estimation of sailing distance, time, and fuel consumption by reflecting weather information and ship characteristics
  • Decide on charter in/out
  • Make a plan for maintenance the ship effectively

Case Study
