Schifffahrt | Shipping HVAC News ENGIE Marenum chillers for Saga Cruises newbuildings Upmost comfort and luxurious ambience play an increasingly important role on modern cruise liners. The right temperature on board ensures for a comfortable atmosphere. Hence, special chillers are needed to meet these very particular requirements on the high seas. The »Marenum« chillers of the Lindau-based company Engie Refrigeration have already been used on frigates for several years. In the future, the civil version of this chiller will also be cooling cruise liners of the British shipping company Saga Cruises. At present, two cruise liners are being constructed at Meyer Werft in Papenburg, Lower Saxony. These vessels are equipped with four Marenum chillers each. In 2019 both cruise liners will be launched in the Baltic Sea. Gusty winds, strong waves and high salt concentrations in air and water – these extreme marine conditions are an enormous challenge for refrigeration technology aboard. Simultaneously, maximum reliability and highest efficiency of refrigeration supply are demanded to grant maximum comfort to the passengers at all times. For these requirements, Engie offers its Marenum chillers, Two new cruise vessels are being built at Meyer Werft, equipped by Engie which are said to be precisely adapted for high sea demands. »The chillers are characterized by compact design, low sound and vibration emission, highest energy efficiency and low maintenance,« Engie says. The technology is reduced to the main components necessary for refrigeration – oilfree compressor, condenser, expansion body and evaporator – and thus saves space in the engine room. A redundant assembly with up to twelve compressors per unit increases operational safety. Thus, the Marenum chiller »can easily be adapted to the individual needs on site due to its modular construction«.

As a key supplier to Seaspan’s Vancouver Shipyards, Bronswerk was awarded a contract worth more than 8,5 mill. € for the design review, manufacturing and installation of the marine grade HVAC-R systems and equipment. The design review, the manufacturing and procurement of the HVAC-R system equipment and components were carried out at Bronswerk’s head office. The production engineering, installation, system integration and testing were performed by Bronswerk’s newest facility in Vancouver. New fan coil units with low profile, low noise and high capacity as well as compact marine duct pre-heaters were developed by Bronwerk’s head office in Montreal.

Schifffahrt | Shipping KNUD E. HANSEN New HVAC business unit for the maritime market The new business unit is also dedicated to cruise Danish naval architect Knud E. Hansen has established a business unit dedicated to »Marine HVAC Design« specialized as an independent detailed design expert providing HVAC related services including 3D modelling. The new unit is owed to company growth and the need for independent experts, the company states. Delivering custom-made solutions based on clients’ interests is thus in focus. The architects claim to have extensive HVAC design capacities already. The Danish experts have a track record of HVAC projects for a wide range of vessels including ships of the defence sector, e.g. the »Queen Elizabeth«-class aircraft carrier and type 26 frigate for the British Ministry of Defence. Further experience has been gained in the cruise segment with an HVAC contract for »QM2« and the more recent »Edge« project. Throughout the design and engineering process, the new business unit will be able to implement numerous tools to increase the efficiency of a maritime HVAC system. This includes the utilisation of various specialised software packages to accomplish tasks such as 2D and 3D visualisations, 3D coordination, outfitting and steel module design, and the calculation of heat loads. Design services will also encompass vessel refits and conversions, Knud E. Hansen says. M Photo: Teknotherm Source: Knud E. Hansen New chiller unit for Stena TEKNOTHERM Chiller for Stena Line Teknotherm’s branch office in Gothenburg has received an order from Stena Line Scandinavia AB for replacement of one HVAC Chiller Unit on »Stena Germanica« – sailing on the route Gothenburg – Kiel. The new chiller unit will have a cooling capacity of 2.000 kW, and features low power consumption due to the energy efficient refrigerant R-134a and compressors capacity control by frequency converters. For easy installation, Teknotherm will deliver the chiller unit in main components and re-assemble the unit on board during normal sailing.
