Severn Trent De Nora, LLC, has been selected to supply Omnipure™ marine sanitation devices and UltraDynamics® ultraviolet disinfection systems for Rigdon Marine's new fleet of ten state-of-the-art 64-meter offshore supply vessels now under construction at Bender Shipbuilding and Repair in Mobile, Alabama.
The Severn Trent equipment is part of a complete on-board sewage treatment plant that rigorously processes and purifies wastewater for overboard disposal.
The UltraDynamics heavy industrial stainless steel ultraviolet systems purify potable water on the new vessels while the custom designed Omnipure marine sanitation systems process all non-oily wastewater.
The decision to process both black and gray water on the vessels was driven by Rigdon Marine's philosophy of building and operating only environmentally-friendly vessels for offshore service.
Larry Rigdon, chairman and CEO of Rigdon Marine, said he selected Severn Trent based on successful experiences with the company on vessels that he had previously designed and commissioned.
New Orleans-based Rigdon Marine plans to operate the vessels under the strict ISO 9000 and ISO 14000 standards, substantially exceeding minimum International Safety Management (ISM) standards.
The first vessel in the Rigdon project is due for delivery by March 2004. After the launch of the first vessel, subsequent vessels are scheduled for delivery every 60 days, with the last one scheduled for August 2005.
