A two-stage freshwater generator will soon join the Alfa Laval AQUA Blue family. Compared to the single-stage AQUA Blue E1, the two-stage AQUA Blue E2 produces twice as much fresh water for a certain amount of waste heat – or the same amount of fresh water using around half the waste heat. Thanks to AQUA plate technology, both models are far more efficient than competing systems.   Matchless efficiency in two stages Introduced in 2008, Alfa Laval’s AQUA plate technology cut the seawater needs and power consumption for freshwater generation in half. Since then, the AQUA Blue family of freshwater generators has steadily grown and improved. In early 2023, the single-stage AQUA Blue E1 will be joined by a two-stage counterpart: the AQUA Blue E2.   “The AQUA Blue E2 has all the strengths of the AQUA Blue E1, including AQUA plates with non-glued gaskets,” says Alfa Laval’s Serdar Sengun, Head of Marine Heat Transfer. “By having two stages, it takes the green benefits even further. Shipowners can get twice the fresh water out for the energy put in, or they can use the added efficiency to save in other ways.”       Support for multiple green scenarios As shipowners move to decarbonize, the two-stage AQUA Blue E2 can support their goals. Doubled capacity compared to the single-stage model can meet an increased need for fresh water, e.g. in connection with alternative fuels. Conversely, it can meet the existing need for fresh water with around half the waste heat input.   Saved waste heat can be used to generate electricity when the Alfa Laval E-PowerPack is also installed on board. But using less heat to produce fresh water can also help meet sustainability requirements. Vessels that must slow steam due to their Carbon Intensity Indicator (CII) or Energy Efficiency Existing Ship Index (EEXI) can retain their production of fresh water with the limited waste heat available.   “Other two-stage freshwater generators can manage these scenarios, but none can do it with the same high efficiency as the AQUA Blue E2,” says Sengun. “That’s because AQUA plate technology uses just half the seawater and electrical power compared to other desalination methods.”   Saving space and time ­as well Despite its wide capacity range, the AQUA Blue E2 handles the entire desalination process within a single plate pack. As with other AQUA Blue models, this creates installation advantages through a small footprint and limited pipework. Non-glued gaskets, which were introduced with the AQUA Blue E1, allow easy maintenance on board.   “The AQUA Blue E2 is a product of superlatives,” says Sengun. “Vessels can produce fresh water of the highest quality with minimal space and effort – and with the greatest energy efficiency.”

A Philippine Navy (PN) frigate that grounded four years ago on a disputed shoal in the South China Sea is back in service after extensive repair works. The PN announced that its offshore patrol vessel BRP Gregorio Del Pilar has been restored to operation after undergoing an extensive overhaul. The frigate went aground on a disputed shoal in the South China Sea on August 29, 2018 and has been out of service ever since. An initial dive inspection found no...

The port of Auckland has come under criticism for multiple failures that resulted in the termination of an automation project for the Fergusson container terminal, costing the port approximately $36 million in investment write-offs. An independent review of the project identified multiple shortcomings, including an insufficient business case for the project, exclusion of senior management in vendor selection and software procurement, and lack of governance and accountability. The review of the governance process of the project, carried out by independent...

Singapore’s Marco Polo Marine wants to capitalize on the fast expanding Asia-Pacific offshore wind energy market after unveiling plans to build, own and operate a new commissioning service operation vessel (CSOV). The company announced that construction of the $60 million vessel is expected to be completed in the first quarter of 2024 and will be financed through existing resources and borrowings from financial institutions. The vessel will be the first CSOV to be designed in Asia.  The decision to invest...

The international shipping industry requires a staggering $1.4 trillion in capital expenditure to achieve a 50 percent cut in emissions by 2050, according to a new report by the UK maritime consultancy UMAS. Funding has been identified as one of the major challenges in decarbonizing shipping, and the Climate Action in Shipping report suggests the industry must find ways to raise $1-1.4 trillion in capital in order to meet International Maritime Organization (IMO) 2050 decarbonization goals. The majority of the...
