Bespoke solutions for changing needs

Our customers have very different needs, so we pride ourselves on our ability to take these needs into account right from a vessel’s construction phase. Our large offering and flexibility help us take varied requirements and changing operating areas into account.

Our systems meet the strictest environmental regulations of the International Maritime Organization, and can also be operated in Environmentally Sensitive Sea Areas (ESSAs) and Special Areas (SAs).

Superior options for all your waste and wastewater needs

We develop our solutions and portfolio constantly to keep them ahead of the competition. For example, our toilets are the most silent on the market, and we are the sole supplier of vacuum urinals.

Our large product range meets the versatile needs of our customers. As an example, our dry waste management solutions include both incinerators for burning waste onboard and different types of compactors and densifiers to reduce the storage volume of waste. A new trend is to have two optional dry waste management lines: one with an incinerator and one with a briquetting unit, packing either recyclable or non-recyclable waste into small briquettes that can be burned or taken to shore. Our different options help customers reduce waste volume in a way that meets their operational needs. For wastewater treatment, we have developed biological and electrolytic treatment solutions for all types of vessels.

Evac Evolution ballast water management system

The Evac Evolution ballast water management system (BWMS) operates effectively in marine, brackish, and freshwater, and has been specified for a range of ships including luxury cruise ships.

Evac Evolution BWMS units are available with capacities ranging from 34 m3/h to 1,500 m3/h, and the equipment can be supplied skid-mounted or in modular form, simplifying retrofits where space is tight.

As an example, 190 m³/h systems have been supplied for two small cruise ships built to accommodate up to 298 people in luxurious suites. Chosen for their compact design and reliability, the units incorporate tank stripping systems that remove sediment from the ballast tanks.

Marine growth prevention systems

Cruise ships use extremely high volumes of seawater, with flow rates often exceeding 15,000 m3/h. Our Cathelco marine growth prevention systems (MGPSs) are able to treat these volumes effectively whilst providing a number of additional benefits. The systems are generally designed with multiple anode installations to protect high and low sea chests that serve the engines and ancillary systems. These may include air conditioning systems, refrigeration systems, and firefighting pumps – all essential to the safe and efficient operation of the vessel.

Operating with copper concentrations of just two parts per billion, our MGPSs can be used to protect the inlets for desalination plants, falling well within the safe requirement of 1.5 parts per million. As no chemicals are involved, the system is also environmentally friendly, helping modern cruise vessels to comply with the requirements of relevant environmental standards. In line with the trend of longer intervals between drydocking for cruise ships, anode replacement can be performed every five years.

Hull corrosion protection systems

We have supplied our Cathelco hull corrosion protection systems, which are based on impressed current cathodic protection (ICCP) technology, to major cruise ship operators including RCCL, NCL, Disney Cruise, and Costa Cruises.
