About us

In most industries, there is an increased focus on the protection of our environment and eco systems. More rules are being adopted, and the maritime industry is no exception.

We clean waste water without dilution or consumables, and we have delivered more than 1,000 systems globally. The process is biological and we have systems living up to the strictest requirements from IMO. This gives you a sustainable solution. You gain operational flexibility while protecting the oceans. A future proof solution.

Customised systems for retrofit

We will deliver customised solutions for your challenges and also retrofit our systems on existing vessels -even into the tightest spaces.

Protecting marine eco systems

We treat waste water biologically, and also have systems for removing nitrogen, phosphorous and microplastic. This means the water let out does not harm ecosystems in the oceans where you operate.

Solutions for special requirements

We have solutions living up to a variety of requirements, meaning that we can deliver solutions for navies, cruise ships, offshore installations and other vessels with unique needs.

A strong industry player since 1945

The company was founded by Haakon Gertsen in 1945 as a maritime agent, and in 1962 Bent Olufsen joined the company to quickly rise to partner in 1972. This created Gertsen & Olufsen, and its future rose when Bo Kristensen joined as CEO in 1993. This line of strong leadership meant Kristensen developed a unique and ground-breaking compensator solution in 1998, placing Gertsen and Olufsen firmly on the world maritime map.

Today we have expanded into the G&O Maritime Group, joining forces with other world-leading maritime suppliers. Product innovations by industry experts creates the foundation on which G&O Maritime Group stands and proves our dedication to innovative solutions to the maritime industry’s problems.

G&O Maritime group was created when Gertsen & Olufsen acquired Atlas Incinerators in 2014. Now, G&O Bioreactors are part of G&O Maritime Group’s Water and Waste Management division. Together we strive to make vessels a greener and safer place to work.
