Pool Participant Companion App for Vessel Performance & Earnings

Context

Hafnia is one of the world's largest product-tanker owners and operators, running pool arrangements on behalf of many vessel-owning participants. The Pool Participant App, launched in 2022, is the companion mobile app that gives those members real-time access to how their vessels are performing and earning — "another step to increase the quality of our service offering," in the words of Hafnia VP Peter Kolding.

My Role

As UI Designer I designed the mobile companion experience — turning dense vessel-performance, pool-points and earnings data into clear, glanceable mobile screens for a non-desk, on-the-go audience.

The Problem

Pool participants constantly needed operational answers — fuel performance, pool points, monthly earnings, contracts, market reports — and getting them meant emailing Hafnia and waiting, which consumed considerable staff time on both sides. There was no single, self-serve place for a member to see the health and earnings of their vessels.

What I Did

• Designed for data density on a small screen — performance metrics like excess fuel consumption, potential fuel savings, total CO₂ emitted and speed-percentage trends, made readable at a glance.
• Designed the pool-points and earnings views — current and historical pool points with consumption indexes, plus monthly earnings by hire days, average net TCE rates and historical trends.
• Put documents in members' hands — downloadable weekly chartering/market reports and pool contracts, archived and accessible from the app.
• Optimized for the inquiry-killing use case — structuring the app so the questions members used to email about are answered in a tap.

Outcome

The app consolidated performance analytics, pool points, earnings, market intelligence and contracts into a single member-facing tool — strengthening the relationship between Hafnia and its participants while generating internal "productivity gains" by reducing the volume of repetitive information requests.

Reflection

With shipping professionals as users, every screen had to survive a five-second glance. The win was ruthless prioritization — deciding what a participant needs first, and letting everything else recede.
