ABS-Certified Transformers
What you need. Where you need it. When you need it.
Life at sea is tough. So are our transformers.
Building transformers for harsh environments has been the core of Virginia Transformer Corp’s (VTC) business for more than 50 years. Marine transformer applications are a natural extension of our business as we provide time-tested products and engineering services to the offshore and shipboard markets. With our certification by the American Bureau of Shipping (ABS) for dry and liquid transformers, we offer marine application solutions for all your generation distribution, propulsion drive systems, oil drilling, and other offshore requirements.
Over the years we’ve evolved from a provider of transformers to a creator of productivity solutions. With competition intensifying globally, marine engineers are continually challenged to deliver the most economical and highly reliable transformers possible.
VTC can help. Our vast experience, broad product offering, and proven performance make Virginia Transformer Corp your choice for success even in the toughest conditions.
MORE THAN QUALIFIED. CERTIFIED.
Our customers aren’t the only ones who think VTC transformers are ideal for offshore use. We’ve met the requirements for Certification of Type Approval from the American Bureau of Shipping.
Type Approval, which is based on several factors such as specific design compliance and quality management, certifies that VTC is an ABS-approved manufacturer of:
- Dry-type and UNIClad® transformers in the 5 kV class within the range of 225 kVA to 5,000 kVA and the 15 kV class within the range of 225 kVA to 3,600 kVA.
- Liquid-filled transformers that are 5 kV class through 35 kV class, within the range of 500 kVA to 5,000 kVA.
VTC has also obtained a UL listing for our dry-type transformers and maintains a quality system in compliance with the ISO 9001 standard.
EXPERIENCE THAT CIRCLES THE GLOBE
VTC’s application-savvy sales engineers, experienced design staff, and manufacturing support team work closely with you to manage all aspects of your shipbuilding, support vessel, oil drilling, or drive systems projects. As a VTC customer, you will deal directly with our experts at our Virginia headquarters and our marine duty and offshore team in Mexico who have the comprehensive skills to oversee manufacturing processes, quality assurance, testing, and shipping. Customers enjoy having direct contact with our applications and design engineers with decades of experience on transformers who are always ready to tailor products to your specific needs.
Our team has extensive experience in meeting the various transformer design and engineering standards set by American and international entities, including ANSI, IEEE NEMA, CSA, IEC, and ABS. Our performance-sensitive level of expertise in both dry and oil marine-duty transformers enables us to manage your most complex projects while meeting your specific design, budgetary, and timeline requirements. Throughout the world, we are here to serve you.
VTC OUTFITS STATE-OF-THE-ART TIDEWATER VESSELS
High tech is a high priority at VTC. When Tidewater, one of the world’s largest generation service vessel operators, wanted to update their fleet with larger diesel electronic propulsion vessels for deepwater drilling, they turned to us. We responded by supplying them with transformers for five anchor-handling towing supply vessels (AHTSVs).
Built in China’s Yantai Raffles Shipyard, these AHTSVs are 280-foot KMAR 404 vessels are designed to transport up to 8,125 barrels of liquid drilling mud, with bulk mud tanks of 10,000 cubic feet at a dead weight of 4.613 long tons and a winch pull of 600 tons. Our work for these cutting-edge vessels has shown the shipbuilding industry the value of transformers that use the latest technology to stand up to the rigors of the sea.
TRANSFORMER FEATURES
