HAMANN AG is supplying sewage and wastewater management systems for three new US REGIONAL CLASS RESEARCH VESSELS currently under construction at GULF ISLAND SHIPYARD in Houma, Louisiana, USA.

The 199 feet / 60 meters long REGIONAL CLASS RESEARCH VESSELS were designed by Glosten from Seattle, USA, in cooperation with OREGON STATE UNIVERSITY. They provide accommodation and workplaces for up to 16 scientists and are operated by a crew of 13. Their purpose is the exploration of the coastal marine environment. The highest environmental protection requirements and the lowest possible noise emission played an important role in the development of the vessels design. The extensive new building project is financed by the NATIONAL SCIENCE FOUNDATION (NSF) and managed by the OREGON STATE UNIVERSITY.

The first of the three research vessels will be launched this year as “RCRV Taani 1” and will be commissioned by the OREGON STATE UNIVERSITY on the west coast as part of the UNIVERSITY-OCEANOGRAPHIC LABORATORY SYSTEM (UNOLS).

The sewage and wastewater management systems on board the vessels are designed to treat black water from toilets and grey water from showers, washbasins, kitchen sinks and laundries, and can process a peak of 6,000 litres of wastewater per day. HAMANN HL-CONT PLUS 025 wastewater treatment plants with IMO MEPC.227(64) and USCG Type 2 (33 CFR 159) certification are used as a basis. The HAMANN DISSOLVED AIR FLOTATION (DAF) technology used in these plants does not require any filters or membranes, making the plants particularly low-maintenance and reliable. Even strong fluctuations in the volume of wastewater to be treated due to fluctuating numbers of people on board are no problem for these plants.

Highly efficient HAMANN grease separators separate the grease components from the galley wastewater to prevent clogging of the pipelines by grease deposits and the formation of hydrogen sulphide in holding tanks.

Automatically controlled HAMANN tank aerators compensate for the lack of oxygen or oxygen consumption in the wastewater holding tanks, which, especially in connection with too high fat contents in the wastewater, promotes the formation of toxic and odorous hydrogen sulfide and ultimately of aggressive sulfuric acid.

The HL-CONT PLUS OCEANCRUISE is certified to IMO Resolution MEPC.227 (64) incl. 4.2 Special Areas and complies with the USCG requirements for Alaska certification.

In addition to the proven HAMANN dissolved air flotation technology (DAF), the new plant series uses two moving bed bioreactors (MBBR). Each system consists of four compact and lightweight modules that can be installed separately, even on different decks. Existing tanks on board the vessel may be converted to function as MBBR modules, saving additional space. With the HL-CONT Plus OceanCruise, HAMANN AG offers a highly customizable solution for both new builds and retrofitting.
The system requires minimal maintenance from the crew, especially by eliminating filters and membranes.
HAMANN offers the HL-CONT PLUS OCEANCRUISE for explorers and cruise ships of all sizes and manufactures every system exactly to the client’s specifications.
