The Boelwerf, initially called J. Boel & Zonen, was a shipyard on the river Scheldt in Temse, Belgium, which produced ships from 1829 until 1994.
During the first fifty years of its existence, the shipyard built wooden ships and employed a limited number of workers.
The leaders of this delegation, Jan Cap (ACV) and Karel Heirbaut (ABVV) often got national attention for their actions.
Due to the international crisis in ship building, the Boelwerf got into financial straits in the mid-1980s and was declared bankrupt on 28 October 1992.
On 12 October 2004, the Boelwerf Vlaanderen board members were convicted of fraud with European education funds.
In recent years, the former industrial estate, measuring almost 87 ha (215 acres), has been turned into an extension of Temse's town centre.
