As an early entrant to the offshore wind market, InterDam developed a range of weight-saving products that comply with the DNV-ST-0145 standard for offshore substations. InterDam’s G21 light-weight sandwich panels provide the most cost-effective solution for internal and external walls of offshore wind substations. As well as reducing topside weight, InterDam’s panels are easy to transport and are easy to install. Hot-work can also be avoided by using our bolted solutions.
InterDam also used its extensive offshore experience to develop a range of fit-for-purpose fire doors that maximize lifespan and minimize maintenance in harsh offshore conditions. Our weather-tight, durable fire doors can be applied both in substations and in the Transition Pieces of the wind turbines.
Products with fire ratings from A0 to H-120 are available, as is rating for overpressure or blast if required. For security purposes, certified burglar-proof up to class 4 and bullet proof up to BR7 can also be provided.
