The Liquid Bulk Solution

A port call can be compared to a F1 pitstop. Various stakeholders each must perform their own activity on a vessel, often in a specific sequence. This complexity is most present amongst liquid bulk vessels. For this reason, Port+ is building a shared, collaborative platform that endeavours to make a port call more efficient by combining data from various sources (open data sources, Port+ data, machine learning algorithms and data directly from participating companies).

The goal is to provide every stakeholder with all the relevant information needed to optimize their planning and perform their activities as efficiently as possible, while at the same time increasing the predictability of those activities.

The combination of these data sources gives stakeholders of the process a highly accurate overview of the different activities taking place – both planned and completed – increasing the efficiency of their planning and operations. This results in a decrease in waste in between activities and hence a decrease in turnaround times for vessels through the port.

“Pushing boundaries in port efficiency”

Involved stakeholders

  • Cargo owners
  • Ship owners & operators
  • Shipping agents
  • Terminals
  • Surveyors
  • Barge operators
  • Bunker providers
  • Shipchandlers
  • . . .


Data runs completely through the NxtPort platform. Data provider keeps control over data at all times.


Reduce time spent planning by having all relevant information at hand. Optimize asset & resource utilization


Decrease port call / vessel turnaround time through optimization of the process and increased predictability


Grassroot approach

The Liquid Bulk Project is initiated in close co-operation with the Port Community. The functional analysis has been designed through multiple co-envision sessions and individual user feedback sessions. This method of working together and continuous feedback allows us to build an application that caters the specific needs of the community.


At the same time, several Proof of Concepts with market leading companies in the sector are being carried out since February 2019. The goal of those PoCs is to further identify user demands and to finetune the data flows in between various stakeholders. The current pilot projects can be divided into three categories as seen below:

Product tanker

Initiated by a large cargo owner
Pinpoint and reduce waste:
Simulate platform

Parcel tanker

Initiated by a ship operator
Reduce time lost in port:
Simulate platform,
contain domino effect.

Tank barge

Initiated by a large chemical company
Optimize jetty occupation for barges:
Simulate platform,
increase transparency


Data hub

The Liquid Bulk Project is a data hub. This means that all participants collaborate with each other towards a common goal. Companies that join the initiative agree to share and consume data based on the principles that are set out by the community. As such, the majority of participants is both data user and data provider. Data can be provided through any means available (e-mail, PDF, Excel etc.) to make onboarding as simple as possible.

Through multiple co-envision sessions, the liquid bulk community has decided that the Liquid Bulk Project should follow a “pay per port call” model. For more information, don’t hesitate to contact our commercial team.

When will we go live

The platform – and associated APIs – are currently being developed. The data hub will be accessible for cargo owners, ship owners/operators, shipping agents, terminals and surveyors starting from the end of this year.
After the initial launch, other roles will gradually be added to the platform.


The following list of companies represents the collaboration of the community during the several co-envisions  that were organised to build the foundation of the Liquid Bulk Project.

Join the initiative

To join the initiative, please contact us via email and we will be in touch with you as soon as possible. Other stakeholder roles will be added in the future. However, be sure to join our community events in order to shape how the future will look like and use the below form to register your company.

The Developers

The Liquid Bulk Project will support both the use of the front-end and consumption of the data through API. 


The Liquid Bulk Project will host a front-end that allows users to get a complete overview about what’s happening with their vessels. The overview consists of a combination of various data streams originating from the different participating companies, Port+ datasets, open source data and algorithms.

At the same time, other functionalities such as an integrated map, will be available through the front-end.

Access-controlled API

Starting from Q1 2020, the data available through the front-end, will also be consumable through APIs. This is mainly for companies willing to integrate the data directly into their backend systems, or those building their own front-end on top of the available data.
