Wastewater management specialist ACO Marine has entered into a cooperation agreement with the Swiss group Sika to optimize the interface connections between the scuppers and drainage channels on board and the deck coverings of a ship.

The development, announced in Hamburg, Germany, at SMM 2018, extends the cooperation agreement Sika Group signed with ACO Marine’s parent company, ACO Group, more than three years ago.

Sika, a leading company in the resin flooring market, and ACO, a leader in the development and manufacture of hygienic drainage systems, initially joined forces to develop evidence-based advice on floor connections -drainage for plant and process facility operators.

The research proved invaluable in establishing a new way of designing soil-drainage connections for land applications and this is now being extended to developing the same for maritime applications.

Lukas Kaisler, Group Management, ACO Marine, said: “Choosing the right type of flooring and drainage system for the operating conditions and site traffic has always been a challenge for ship operators. We can now exploit the results of the initial research to develop new interface solutions for use on board ships. »

The connection between the scuppers and the channels and the floor of a ship is a critical point because it is possible to have a break in the connection – due to a dynamic and/or thermal load – which can lead to water infiltration, corrosion of deck structures or delamination of the floor. Water seeping into the ground from gutters can also create an ideal breeding ground for bacteria, a major concern for passenger ship operators in particular.

Tony Jenkins, Corporate Business Development Manager – Marine, Sika Services AG, said: “We are delighted to have extended the cooperation agreement we have in place with the ACO Group to now include its marine division, ACO Marine. The results of the initial study will now be developed specifically for marine applications, allowing Sika and ACO Marine to develop guidelines and solutions to optimize interface connections between onboard flooring and drainage systems. ships.

Mark Beavis, Managing Director of ACO Marine, said: “Drainage floor connections currently used in the marine industry can become damaged after a few years of operation, often requiring extensive and costly floor repairs or replacement. To avoid downtime, hygienically designed flooring systems and drainage systems should be carefully selected for the various parts of the ship – engine rooms, galleys, laundry rooms, cabins, swimming pools, etc.

“As no guidelines currently exist, ship operators and shipbuilders have so far used trial and error when selecting the correct flooring and drainage system. However, from this cooperation, we aim to optimize the connection between Sika flooring systems and ACO Marine drainage systems and establish sound guidelines for their installation and use.

The results of the joint research project are expected to translate into direct cost savings. Jiri Lonicek, Head of Product Management, ACO Marine, said. “We will communicate the research results to shipowners and shipbuilders so that they can benefit from reduced maintenance costs and reduce possible bacterial contamination for a safer and more hygienic environment for passengers and crew.”

ACO Marine showcased a potentially new drain interface connection at the SMM event. A meeting table in both company premises was fabricated from Sika flooring material with an ACO Marine drainage system and a through-the-mid interface.
