Cold Ironing, Shore Power, Onshore Power Supply (OPS), Shore Side Electricity (SSE), AMP (Alternative Marine Power cables)

Tratos’ robust Alternative Marine Power Cables (AMP) provide the high-voltage shore connection (HVSC) used to supply ships with electrical power from shore.

The process has many denominations and acronyms — Cold Ironing, Shore Power, Onshore Power Supply (OPS), Shore Side Electricity (SSE), AMP (Alternative Marine Power), and more, but all of them refer to the same thing and serve the same purpose — Namely the process of bringing power from the onshore grid to the vessels moored in ports worldwide.
Tratos draws upon several decades of experience as a recognised specialised manufacturer and supplier of reliable, robust cables for arduous applications such as the mining industry and flexible power cables for cranes used in Ports worldwide.

Dedicated product engineers and sector specialists understand the special requirements needed for reliable and consistent performance in the harshest marine environments. It is this knowledge that ensures Tratos’ AMP Cables meet or exceed the requirements of Internationally recognised industry standards (e.g. IEC IEEE 80005).

Tratos are aware of the importance of satisfying our customers. They are committed to complying with all customer, legal, statutory and other requirements, along with the continual improvement and effectiveness of our Quality Management System which satisfies all the requirements of ISO 9001: 2015 certified by BSI (UK). Tratos manufacturing sites also hold Environmental and Occupational Health & Safety Management System approval.

Tratos selects only the best quality of materials for its manufacturing processes, testing performance and guaranteeing quality. Tratos products are RoHS compliant. Today the Tratos Group enjoys a reputation as one of the industry’s most trusted suppliers.

Due to the use of rubber insulations, fillers, and sheaths developed and mixed internally by Tratos, Tratos Alternative Marine Power cables can operate in temperatures from -50ºC to +90ºC. The robust rubber insulations and sheaths used by Tratos ensure outstanding abrasion resistance, flexibility and physical protection.

The latest generation of cables combines tried and tested manufacturing techniques with state-of-the-art technology to create phenomenal strength and flexibility cables.
As the actual manufacturer Tratos can produce not only cables in accordance with IEC IEEE 80005 and also bespoke designs (Tratos Tailormade) with reflective & fluorescent sheaths.

What are the Advantages of Shore Side Electricity?

  • Elimination of ship engine emissions in port areas (SOx, NOx, PM, CO2)
  • Elimination of noise and vibration caused by ships at berth
  • Improvement of working conditions and safety in ports
  • Compliance of vessels at berth with International Maritime Organization (IMO) requirements
  • Fuel cost savings, as onshore electricity, may be less costly than using onboard generators

Shore power may also extend the service life of auxiliary generators, reducing maintenance costs and encouraging a more sustainable machinery use.

Tratos Alternative Marine Power Cables can be found in harbours and ports worldwide, as shown in the case studies below.
