Argentina: Risk of Grounding within the Parana River

North’s Argentinian P&I correspondent, Pandi Liquidadores S.R.L, has reported that four vessels have grounded in the Parana River in recent weeks.

The vessels grounded in the area of Isla Del Diablo and Isla Del Medio, between km 286 and km 290, where ships are required to make two sharp alterations of course in the leg known as Paso Abajo Los Ratones.  The prevailing current in this area is approximately 2.5kts downstream, but this may vary depending on the available depth of water.

It is suspected that vessel’s navigating within the channel have been heavily influenced by the speed and direction of current which has resulted in their loss of control and subsequent grounding.

Although the authorities are reluctant to issue an official notice, they have indicated that all ships navigating through the Paso Abajo Los Ratones must remain within the dredged channel.

North’s correspondent recommends that a suitable passage plan should be discussed with the pilot prior to commencement of the river passage.  This will enable the Master to become familiar with the crucial stages of the river passage and ensure that the pilot is fully familiar with the ship’s manoeuvring characteristics. 

The Master should also monitor the electronic charts used by river pilots and ensure the ship maintains the required 2 foot under keel clearance at all times.
