Finnish shipping technology pioneer Laura Langh-Lagerlof is continuing to drive innovation in a traditionally male-dominated sector.

Born into the shipping family behind containership owner Langh Ship, Langh-Lagerlof founded Langh Tech in 2015 and still owns the company.

The latest product to roll out of the factory near Turku is a new smaller ballast water management system (BWMS) for tight spaces on vessels.

These systems purify ships' ballast water to prevent the unintended spread of invasive marine organisms.
