The Hyatt Regency Saipan is a premier 5 Star luxury hotel located at the famed white powder sand Micro Beach facing the emerald colored lagoon of Saipan, Northern Mariana Islands.(http://www.saipan.regency.hyatt.com/en/hotel/home.html) The Hyatt Regency prides on ensuring clients enjoying a stay more than welcomed, and places the highest possible standard in ensuring its facilities are more than capable to safely and adequately serve the needs of its valued clientele and to be in full complaince with US Drinking Water standards.
In early 2015, the Hyatt Regency Saipan began experiencing high levels of occupancies that resulted in the need to purchase trucked water to meet the resort operations. Trucked water poses three issues; lack of control of the quality of water, the inability of suppliers to meet the resort needs, and the excessive cost of purchased water.
Over the years, the Hyatt Regency had depended on water produced by two Ionics 80,000 Gallons Per Day seawater reverse osmosis plants installed in the mid 90's. Hyatt Regency was primarily concerned with the reliability of both plants as well as their immediate production shortfall.
Hyatt was faced with a need to address immediate capacity shortfall of about 30,000 gallons per day of potable water that met US drinking standards, the need to improve reliability and efficiency of both the older units and new unit and allow for future expansion within its existing premises located on a second floor with restricted access doors with 34 inch openings.
Pacific Century Inc., with Gemini Seawater Systems LLC proposed two alternate solution to first install a customs designed modular system to address the capacity shortfall. The access issues required that the plant components could only be integrated at site. As the Ionics units were nearly 20 years old, and the sensors most likely inaccurate, the recovery rates of the Ionics units was an unknown factor that could impact availability of feedwater for the new unit. A custom designed 40KGPD seawater plant that could be expanded to 80KGPD was proposed to the Hyatt Regency. The unit would be built at site to completely avoid any site demolition and construction. The unit would integrate into the existing feedwater supply, pemeate piping, post treatment and discharge infrastructure. To address risk of insufficient feedwater capacity, the unit utilized a variable frequency driven Danfoss Axial Piston pump and two throttle pressure valves.
Hyatt Regency obtained competitive bids from three other desalination vendors and contracted Pacific Century for the project. The selection fo Gemini was based on the expected total installed costs and the potential for future expansion at the existing facilities, the use of superior components for seawater conditions, and the experience capability to modernize the Ionics units.
The components for the BX-40 unit were shipped on 4th November 2015. On site installation began on December 3rd, and the Gemini BX-40 unit commenced producing water for the Hyatt on December 12th, 2015.
During the time of acceptance testing, a well head failure resulted in the Hyatt not being able to supply sufficient feedwater to allow the Gemini BX-40 to produce the rated 40,000 gallons per day. The VFD Drive and throttling pressure valves allowed the plant to utilize the available feedwater and ensured that the Hyatt Regency had sufficient water until the damaged well is repaired.
Pacific Century and Gemini worked even the weekends to train the Hyatt Regency's engineering and operations team to become familiar with the all aspects of operations and maintenance of the new plant.
The Gemini team also reviewed the Hyatt Regency's Ionics units and the entire process flow of desalting water and assisted the Hyatt Regency engineering team to become aware of the critical improvements required on their existing facilities.
That Gemini BX-40 Seawater Plant, which is expandable to 80,000 Gallons per day and capable of achieving energy efficiency of 10kwH/1000 gallons of water produced, has resulted in the Hyatt Regency being able to meet current water needs and be able to expand to meet future needs. Such capability allows the Hyatt Regency Saipan to continue in what it excels: to make the Hyatt Regency's clientele feel more than welcomed through superior facilities and genuine warm hospitality for a fantastic and memorable stay.
