CHALLENGE

Achieving a sustainable future at sea

The marine and maritime industries face increasing pressure to reduce emissions to air and water, improve energy efficiency and comply with stricter environmental requirements.

Among other things, vessels need greener propulsion systems, smarter energy management, and advanced water treatment solutions that minimise environmental impact throughout their operational life cycle.

MARKET POTENTIAL

A growing global market

The maritime industry is undergoing a rapid transition driven by regulation, cost pressures and sustainability requirements. Global demand for low and zero-emission solutions is accelerating as shipowners and operators strive to meet emissions reduction targets, including those set out in the IMO GHG Strategy.

A significant share of the market is also driven by retrofit opportunities, where existing vessels are upgraded with more energy-efficient and low-emission solutions.

HAV Group has four subsidiaries: HAV Design, Norwegian Electric Systems (NES), HAV Hydrogen and Norwegian Greentech. With its widespread expertise and broad portfolio of solutions, the Group is well positioned in this fast‑growing market.

HAV Group’s integrated portfolio reduces complexity and risk for customers, strengthening its position in this growing market.
