Voyage planning

ISSUE: Planning an energy efficient voyage

Effective leg and voyage planning is important when optimizing the ship's energy efficiency. This applies to virtually all types of cargo and passenger vessels, whether their sailing routes vary or stay the same over time. Vessels on fixed schedules need to address route administration in order to establish benchmarks with fixed legs and voyages. This enables the vessel operator and fleet managers to monitor and report on energy performance in a structured way, allowing for further improvements in energy efficiency. In many cases, significant fuel savings are attainable by effective planning of the sea passage. The optimum route and improved efficiency can be achieved through the careful planning and execution of voyages.

SOLUTION: The Marorka Voyages Unit

The Marorka Voyages Unit gives a comprehensive overview of current and past voyages and is used to create points in time, which are used to divide data between voyages and legs, to analyze data and to perform certain functions on data, such as accumulation and averaging. This is the basis for the generation of energy-focused reports for individual legs or entire voyages.

Key features of the Voyages Unit:

• Route administration

• Current voyage and leg overview

• Past voyages and leg overview

Route administration is used by the crew officers to plan legs and voyages, as well as waypoints between harbours. The planning includes the timeframe for sailing between harbors and the waypoints between them. The waypoints between ports can be added automatically from ECDIS or added manually.

The Voyages unit also gives means to easily register and keep track of the operational states of the vessel using the State Manager. The main states are “Sea Passage”, “Port” and “Other State”. Using the state registration, all data can be analyzed with respect to different operational states, and functions such as accumulation and averaging may be applied for each state over certain time periods.
