A2SEA’s problem

Off the mainland coast, an offshore construction vessel, A2SEA’s Sea Challenger, found itself to have met the capacity of its biological sewage treatment plant. A four-month project caused an increase in personnel on board the vessel and meant a quick solution for waste water treatment was needed.

A temporary solution needed

Subsequently, an increase in personnel capacity on the jack-up vessel meant that a temporary container city was built on the deck of the vessel.

Our resolution

When contacted, G&O Bioreactors offered to deliver a sewage plant fitted into a container. This was a plug-and-play solution, meaning that the sewage plant only had to be connected to the power supply of the vessel. Also, the container could be integrated into the temporary city, built on board the main deck of the jack-up vessel.

“By renting, we did not have to build a new or expand our current plant. Furthermore, by expanding the capacity of the current sewage plant, we would have a permanent overcapacity when the situation was back to normal again. With the timeline in mind, the project only lasting for four months, renting was the most viable solution – from an economic point of view.” – Steen Ludvigsen, Fleet manager A2SEA
