Investigation report into grounding published

On July 16, 2024, the Transport Malta’s Marine Safety Investigation Unit has published an investigation report into the loss of propulsion and subsequent grounding of the 'Mazarine' on Wolf Rock off Land’s End, UK on July 10, 2023. The vessel sustained structural damage to the underwater section of the hull. In addition to the hull perforations, several deformations were observed, mostly on the port side. The Transport Malta investigation determined that the ship ran aground following the failure of an elbow fitted on the vessel’s main engine lubricating oil system, leading to the loss of a significant amount of lubricating oil and a drop in the main engine lubrication oil pressure. The safety investigation identified how the engine-room crew members made two desperate attempts to restore the main engine’s lubricating oil system, working under significant time pressure given the vessel’s proximity to the rocks. The safety investigation report makes two recommendations to the Company and the engine manufacturer. – It was not excluded that the initial cause of the pipe elbow failure was fatigue due to alternating stresses, possibly caused by high levels of vibrations and / or bending forces resulting from the degradation of the flexible rubber bellow; – The loss of the main engine LO pressure was the cause of loss of propulsion, which eventually led to the grounding, after the vessel lost headway. – The subsequent failures were due to failure of the attempted resin compound repair and the poor repair welding of the lamellar cast iron under demanding conditions; – The inability to either drop the anchor (due to the water depth), or lay out the cable in a controlled manner (due to the rate of drift), significantly reduced the likelihood of the anchor holding; – A spare pipe was not available on board; – The two attempts to repair the LO pipe were made under intense working conditions; – Surface preparation for the weld was very challenging and LO may have been present during the repair weld – The actions concerning the lights, shapes, and the AIS, that were then taken to show that the vessel was NUC, were timely in warning Ferro and allowing Falmouth Coastguard to notice the situation; – The subsequent actions taken immediately prior to, during, and following the grounding on Wolf Rock with respect to the safety of the passengers and crew, and the assessment and control of the damage were timely and successful; – The master considered using both anchors, but opted not to because he was concerned of the possibility of the anchor cables twisting and becoming fouled; – A technical fault on the VDR prevented the successful downloading of the data. In view of the conclusions reached and taking into consideration the safety actions taken during the safety investigation, Anglo-Eastern Ship Management (NL) BV is recommended to investigate the level of vibration in the LO pipe elbow and take corrective action if the findings so warrant. MAK is recommended to issue a service bulletin to engine operators to carry out non-destructive testing (NDT) on similar pipes to check for cracks.

MAZARINE undergoing conversion in Poland

CLdN has sent its 2,907-lanemetre MAZARINE to Remontowa Shiprepair Yard in Gdansk to add an extra trailer deck above the weather deck similar to OPALINE and sister AMANDINE which were enlarged prior to their delivery from builders Flensburger Schiffbau-Gesellschaft, increasing the intake to 3,923 lanemetres.

Cooling water system leak

The "Mazarine", en route from Rotterdam to Dublin, was disabled and went adrift due to water leaking in the cooling system of main engine on April 17, 2019, at 1.40 p.m. The crew completed repairs, and the ship resumed its voyage at 2.30 p.m. and entered Dublin port on April 18 at 7.30 p.m.
