Last month Hydrex mobilized a diver/technician team to a 145-meter general cargo vessel in Las Palmas, Spain when oil was leaking from the stern tube seal assembly of the ship. The team used the Hydrex flexible mobock technique to create a dry working environment around the assembly and replaced three damaged stern tube seals on-site, in drydock-like conditions.
A 190-meter bulker had suffered a bent propeller blade. Hydrex was therefore contacted, and rapidly mobilized a diver/technician team to Rotterdam to perform a detailed underwater inspection and repair of the damage in early January. Later that month a team carried out a similar operation in the same port on a 230-meter vessel.
The team found that one of the propeller blade tips of the first vessel was deformed over an angle of 30° and proposed a straightening with the in-house developed cold straightening machine. The inspection of the second vessel revealed that all four blades were bent over angles ranging from only 3° to 35°.
Last month a Hydrex diver-technician team performed a crack repair on the pintle area of the rudder of a 181 meter tanker and performed a detailed inspection of the stern tube seal assembly of the vessel while it was berthed in Ghent. Following this inspection the team replaced the worn seals and installed a spacer ring, thus creating a new running area for the seals.
For years cofferdams (called mobdocks in Hydrex terminology - short for 'mobile mini dry docks') had to be large metallic structures that make a watertight fit to the hull of a vessel in order to seal out water from the area that is being repaired. Hydrex has pioneered many different uses of mobdocks including sealing off thruster tunnels at both ends before removing the water and creating a dry space within.
Eems Transporter' April 2011. Grounding off Karpathos On 3 April the general cargo vessel 'Eems Transporter' ran aground off Karpathos Island, Greece. The unfortunate vessel was heavily aground on rocks.
LOF After an initial refloating attempt by using a tug only, SMIT Salvage together with Megatugs were contracted on 9 April under Lloyds Open Form terms and conditions to refloat the stricken vessel.
