FIELAX GmbH

BRIEF ACCOUNT

FIELAX GmbH was founded in 2002 and is based downtown the German North Sea port Bremerhaven. The founders previously worked as scientists within Germany’s polar and marine research and for a shipping company with strong commitment to research vessels. FIELAX offers scientific technical services and products for research and shipping. Our highly qualified team of scientists and engineers has longstanding experience in surveying operations on land and sea. Our clients benefit from this experience and from our expert knowledge in physics, geophysics, chemistry, mathematics, hydrography, information technology and electronics.

WIND ENERGY PRODUCTS AND SERVICES (ON- AND OFFSHORE)

Offshore power cables laid in sediments are designed for certain maximum core temperatures during load and exceeding these temperatures can lead to permanent damage to the power cable. The ambient temperatures and the thermal conductivities of the sediments have a direct effect on the heat loss (cooling) of buried cables and consequently on their core temperatures. If the sediments do not allow sufficient cooling of the cables, their critical temperatures may be reached already during a regular power transmission and not only under full load.

Therefore, the thermal conductivities of sediments along proposed routes for underground power cables are of interest to the offshore industry, and the demand for these measurements is steadily increasing due to the rapid development of offshore renewable energy. FIELAX offers measuring the in-situ temperature and thermal conductivity down to 6m below the sea floor. Also, we offer computer modelling based on in-situ measured sediment properties and water temperatures to estimate the thermal energy dissipation mechanisms and the environmental impact of submarine cables.
