MAN Powers Fall-Pipe And Rock-Dumping Vessel

Posted on April 12, 2010

Construcciones Navales del Norte, Spain, recently delivered the "Simon Stevin" to Jan del Nul. The vessel, a fall-pipe and rock dumping ship with a capacity of 19 500 cu.m, is driven by an MAN Diesel diesel-electric propulsion system comprising a series of 32/40 engines.

The "Simon Stevin" is configured with five nine-cylinder 32/40 engines, each delivering 4500 kW at 720 rpm. The engines were manufactured by STX Engine Co. Ltd., MAN Diesel's Korean Licensee. The engines drive an electric power plant that produces enough power to power a city of 130 000 people, said the ship's owner.

The "Simon Stevin" will mostly be deployed in offshore applications, such as the laying of oil and gas pipes at great depths; the vessel was designed to level the seabed and dump rocks down to a depth of 2000 m. According to Jan de Nul, the fall pipe can process rocks with a diameter up to 400 mm, a figure greater than any other fall-pipe vessel in service.
