Sea Trucks has just completed successful sea trials of the DP3 offshore construction vessel Jascon 18 (photo) in Singapore. Imtech Marine and Radio Holland supplied the propulsion and power distribution systems as well as the nav/com systems.

Jascon 18 features a 1,800-ton crane, 1,800 sq m deck and a 750-ton pipelay system. Capable of performing a wide variety of marine construction and pipelay tasks in both ultra deepwater and continental shelf environments, the vessel’s hull was built in China and the outfitting was done in Singapore. Imtech Marine in Rotterdam commissioned the thrusters and switchboards and the company’s engineers in China assisted with the low voltage switchboard, while Radio Holland Singapore commissioned the nav/com systems.

Pleun Noteboom, Imtech Marine project manager of the Jascon 18, comments: “The project has been run with a dedicated team with engineering support from our colleagues in China and Singapore, which has proven to be of great benefit for both the customer and Imtech Marine. We were close by in Asia to work on the project.”

The total scope includes the high voltage (6.6kV) main switchboards and low voltage switchboards, main thruster propulsion drives including the thruster motors, the retractable azimuth thruster and bow thruster propulsion drives, distribution transformers, nav/com equipment, as well as project management, design, engineering and commissioning.

“This project had been subject of some delays so it was a challenge to start up systems and commission the installation in a fairly short space of time. So we are pleased that the sea trials have been successful and that the thruster drives performed very well,” says Pleun.

The next vessel, the Jascon 35, for which Imtech Marine has already delivered some parts, is expected to get underway for outfitting end of this year or in the beginning of 2016.
