Veslink - MRV Reporting - Relevant Datasets

Veslink standardizes voyage communications to help you collect and analyze current positions and other critical voyage data and share information with a network of trusted partners.

Voyage Leg Summary

The Voyage Leg Summary dataset contains many notable fields that make it particularly useful for MRV reporting. It contains data about completed portions of a voyage itinerary, specifically with a focus on vessel performance during that leg. This includes fields like port time, sea time, and berth time, as well as bunker consumption. Data appears in the Voyage Leg Summary dataset only when the leg is fully complete. For sea legs, this means a row appears when a vessel has departed a port and arrived at the next destination; for port calls, this means a vessel as arrived and departed the port.

Per Bunker Type Consumption

IMOS is able to track up to six bunker types per vessel. Additionally, IMOS tracks consumption details for three primary categories: sea, port, and berth. For each combination of bunker type and category, IMOS contains the following data:

CO₂ Emission: A calculation of total CO₂ Emission using the CO₂ Emission Factor and the coefficient.
CO₂ Emission Factor: Pulled from the Fuel/Lube Types master data configuration in the Data Center.
Constant: EEOI emission factor, from the IMOS Extra Information for Report form.
Per Day Consumption by Category: The average consumption per day spent in the category (sea, port, or berth).
Total Consumption: The total consumption for the whole voyage leg.
Total Consumption by Category: The total consumption for the whole voyage leg by category.

Category Hours

The Voyage Leg Summary contains the total hours spent at various points within a voyage leg:

Berth Hours: The total time spent at berth during a port call, calculated as the time between between All Fast and Departure.
In Port Hours: The total time spent during a port call, calculated as the time between arrival and departure.
Shifting Hours
Steaming Hours: The total time spent steaming at sea, calculated as the time between departure and arrival.
Time Elapsed at Anchorage: The time elapsed at anchorage while awaiting a berth; calculated as the time between Port Activities AL and AF.

Transport Work

The following data are used in total transport work calculation (cargo carried × distance traveled), which MRV regulation indicates should exclude ballast legs (BL Qty = 0):

BL Qty per leg
Berth Distance
In Port Distance
Shifting Distance
Steaming Distance

Voyage Leg Details

Deadweight

In the Voyage Leg Details dataset, the source of Deadweight (DWT) depends on the Event Type:

Noon, Arrival at Port, and Departure at Port use the leg Activity Report Deadweight value.
Arrival at Berth uses the previous leg details' Deadweight value.
Departure from Berth uses the upcoming leg details' Deadweight value.

Leg Delays/Events

Berth Events

The IMOS Leg Delays/Events form maps to berth events in the following way:

Reasons = Berth Events

Leg Delays/Events captures all required information for MRV and, consequently, houses all information required for MRV report definitions.
