TEAM SAIL

Underwater Bow Thruster Removal

Photo: Hydrex

A Hydrex diver/technician team mobilized to Rotterdam last month to remove the bow thruster of a 300-meter container vessel. The unit needed to be overhauled. Hydrex performed the operation underwater using the company’s own workboats based at the Antwerp depot. This made it possible for the owner to keep his vessel out of drydock. The team mobilized from the Hydrex headquarters in Antwerp after all basic preparations had been made and the needed equipment was loaded onto one of the Hydrex workboats. The Hydrex catamarans are fully equipped as dive support stations with hydraulic cranes, winches, nautical and communication equipment and a dive control room. They can be used for a wide range of operations in Belgium, the Netherlands, the United Kingdom and France, permitting even more rapid deployment from the Antwerp depot. This increases flexibility of operations and helps to keep costs down for the client. After they arrived in Rotterdam, the divers installed flexible mobdocks on both sides of the thruster tunnel. Next they emptied all water from the tunnel. This created a dry working area around the bow thruster unit. The team could then detach the bow thruster blades one by one. The blades were replaced by a blind flange to prevent oil leaking from the thruster and water from ingressing. Next the diver/technicians removed the flexible mobdocks again, concluding the first part of the operation.

The speed sailing boat smashes the current record in Walvis Bay, off the coast of Namibia. The new world record of 59.23 knots (109kph) set the best average time over 500m and broke the previous mark of 55.65 knots with a peak speed of 63 knots (119kph). Two days later the team improved this speed with a 59.38 knot run which peaked at exactly 120kph (64.78 knots). During the same run the team also smashed the nautical mile world record* with an average of over 55 knots

A Sao Tome-registered ship carrying charcoal from Somalia to a Gulf Arab state was gutted by fire while sailing near Yemen's Soqatra island in the Arabian Sea, Reuters reported. They said authorities did not send rescue teams from Aden to help the stricken vessel, whose name was not immediately available, because ships would normally take two days to reach the location. Instead, port officials contacted ships sailing in the area to try to help the vessel


Leaking Tanker Not Permitted to Enter Ports

Underwater repair allows vessel to continue its schedule.   When the fore as well as the aft stern tube seals of a 247-meter tanker were leaking, the vessel was not given permission to enter any ports. Unloading the vessel at sea and going to drydock seemed the only option for the vessel, until Hydrex sent a diver/technician team with one of the company’s flexible mobdocks to the ship’s location in Port Gentil, Gabon, to replace both sets of stern tube seals on-site.
