Bow Thruster

Underwater Bow Thruster Reinstallation In Tacoma

Picture 01.jpg

Three months after Hydrex diver/technicians removed the bow thruster of a 294-meter container vessel in Tacoma, a Hydrex team once again mobilized to this location to reinstall the overhauled unit underwater with the use of the Hydrex flexible mobdock. The superintendent of the ship was very satisfied with the first part of the operation. The job was completed well within the available time frame thanks to good team work of the Hydrex divers, the ship staff and the floating crane operator.   For this reason the customer asked Hydrex to take care of the reinstallation as well, which was carried out last month. Together with all the necessary equipment, the team mobilized from the Hydrex office in Clearwater, Florida to the vessel’s location. After they set up a monitoring station on a workboat, the team positioned the bow thruster onto a cradle.   This cradle was designed especially for thruster operations. It can be adjusted to the size of the unit. In this manner the thruster is prevented from tipping over, making it much easier to handle. The Hydrex divers could lower the unit into the water and maneuver it inside the thruster tunnel in one take. The team positioned the bow thruster and secured the unit. The team then used the lightweight flexible mobdocks developed by Hydrex to close off the thruster tunnel on both sides
