- Marine & Offshore Transformers
Overview
ESTA Transformer designs and manufactures transformer solutions for marine and offshore applications using a fully engineered-to-order approach, rather than catalogue-based products.
Marine and offshore environments impose demanding conditions such as high humidity, salt-laden atmosphere, continuous vibration, restricted installation space, and uninterrupted operation requirements. These conditions require a dedicated engineering discipline that goes beyond conventional industrial transformer design.
For marine and offshore projects, ESTA focuses on:
- Application-specific engineered-to-order design
- Electrical and mechanical structures tailored to marine conditions
- Long-term operational reliability
- Full compliance with international marine standards
- Project-specific testing and validation
Application Areas
ESTA marine and offshore transformer solutions are used in the following applications:
Tugboats and workboats
Cargo and container vessels
Offshore oil & gas platforms
FPSO / FSO units
Offshore substations
Marine auxiliary power systems
Deck equipment and marine process systems
