Comprehensive expert support through our global service network

Our reliable and proven systems for offshore vessels and rigs have a long lifespan and are simple to maintain – an important factor given the limited possibilities for service and maintenance in these environments. We can provide on-site maintenance as well as troubleshooting assistance by phone and email. For comprehensive coverage that offers you peace of mind, we also offer service contracts. Our service technicians are experts in their field, and include those with Basic Offshore Safety Induction and Emergency Training (BOSIET).

Ready to meet your changing needs

The nature of the offshore industry means that vessels and platforms are likely to operate in a variety of different areas over their lifetime, and this must be taken into account during the design and construction phases. A change in operating area may mean a change in water and waste management requirements, and with our extensive offering we can support you in every eventuality.

Our systems comply with the strictest International Maritime Organization regulations and are also suitable for use in Environmentally Sensitive Sea Areas (ESSAs) and Special Areas (SAs).

Evac Complete Cleantech Solution 

Purchasing all your waste, wastewater, and water management systems from a single supplier brings many benefits for both the shipyard  and the operator.

Accommodation vessels and platforms

We offer solutions for vessels with capacities ranging from a few dozen people to thousands of crew.

Our NORSOK-approved toilet and wastewater treatment systems – including large-scale
membrane bioreactors and sludge driers – are found aboard three state-of-the-art semi-submersible accommodation vessels, known as floatels, operated by Floatel International.

Pioneering spirit of Allseas

Support vessels

Our systems are trusted by operators of offshore support vessels as well as other types of specialized vessels from around the world.

Pioneering Spirit – a vessel for single-lift installation and removal of large offshore oil and gas platforms, and the installation of oil and gas pipelines – relies on Evac systems. It is the largest vessel ever constructed in terms of gross tonnage, breadth, and displacement. We supplied vacuum collection systems including two ejector vacuum units, 320 vacuum toilets, and four transfer units for black and gray water – as well as wastewater treatment systems including two membrane bioreactor units.

Drilling rigs

We also offer solutions for drilling and jack-up rigs. These platforms have varying needs and operational conditions, as well as limited opportunities for service and maintenance, so we focus on simple and reliable construction.

Thanks to our global service network we can offer support, spare parts, and service in 40 countries across six continents.
