The heating of oil pipelines at great water depths is a very specific and complex application field for electrical heating systems. An electrical heating system is absolutely essential to guarantee reliable, constant oil production for such a specific application. The hot oil from the crude oil deposits cools down significantly in the considerably lower ambient temperatures found on the sea bed. There is a great risk of the emergence of wax and hydrate formations.

Heating the oil pipelines at great ocean depths requires a high degree of expertise and places considerable demands on the heating tape. BARTEC as a specialist in electrical trace heating systems has developed the heating cable Deep Sea Star® for pipe-in-pipe applications. It prevents the emergence of wax and hydrate formations of the oil. The crude oil remains free-flowing regardless of the prevailing ambient conditions.

A heating circuit length up to 20 km using just one feeding point is possible with the system. This reduces material and assembly costs. The heating cable is extremely strong and can reliably withstand the high required temperatures. It provides the highest rated voltage with up to 5.000 V per phase. The quality has been confirmed by Sira in accordance with the international standards IEE844-200 and IEC 60079-30-1.
