Tackling blast-proofing

Just seven years after launching, fire- and blast- resistant door and wall manufacturer InterDam has added some impressive names to its project portfolio.

The firm, which opened a new office and fabrication facility in Ridderkerk, Netherlands last year, is supplying heavy-duty fire and blast resistant doors for Shell’s Prelude floating LNG project, currently under completion in South Korea and due onstream offshore Australia in 2017.

It previously supplied products, including external doors, for BP’s Northstar artificial island project in the Beaufort Sea, offshore Alaska, and all walls and doors for Tennet’s HelWin2 project HelWin Beta offshore wind transformer platform, which set sail from Heerema Fabrication Group’s Zwijndrecht yard, Netherlands, 14 June. The three projects alone site the firm’s products across three continents.

The key is using a fiber-bonded insulation material based on calcium silicate, Berend Groeneveld, InterDam’s managing director, says. InterDam has used the material, which weighs 300grams/sq m, sandwiched between grade 316 stainless-steel sheets, for its A60-rated (fires without oil) and G21 FirePanel, which requires bolting only for the substructure. It also has a H120-rated version (for oil pool fires up to two hours), using a pre-coated steel sandwich panel, certified by DNV GL last April.

“We are a relatively young company, but we have experienced people,” Groeneveld says. He says many are still using products designed and certified in the 1970s-1990s, while InterDam has spent over €2 million on product development, and now has a standard product range, certified to DNV GL, Lloyds, standards. But, he says the firm wants to go further.

Calcium Silicate-based products are now well-established as a fire resistant materials in the industry. Stone wool, which is also used, offers little resistance against blasts and asbestos, which is now banned, Groeneveld says.

InterDam has certified an easy self-drilling and self-tapping installation method for walls and doors to reduce installation time. It has also developed the Ergo Latch, a mechanical product that allows sliding doors weighing more than 150 kilo to be opened using two fingers, without using electronics or hydraulics, to meet NORSOK standards.

The firm, whose turnover is currently split 50/50 between renewables and oil and gas,is aiming to grow its turnover to €20 million by 2015.
