She was built by Sønderborg Skibsværft A/S in Sønderborg, Denmark. Christened Leila Bech, she was launched on January 12, 1974, and was commissioned under the Danish flag on May 1, 1974. After sailing under the Panamas and Ilaian flags, she was finally purchased by the Turkish private maritime company in October 2013 as the first and so far the only non-governmental vessel of her kind. She was renamed "Denar", short for "Deniz Araştırmaları" (literally: sea surveys).
She made her first operation in the Mediterranean Sea for the Northern Cyprus Water Supply Project, an international water diversion project designed to supply water for drinking and irrigation from southern Turkey to Northern Cyprus via undersea pipeline. With the help of her two remotely operated underwater vehicles (ROV), she was put into service at the construction projects of Marmaray, İzmit Bay Bridge and Yavuz Sultan Selim Bridge in addition to deep sea surveys.
