Rena Summary (November 1 to 26)

Rena Summary (November 1 to 26)

Oil Recovery

The final 319 tons of heavy fuel oil was pumped from the Starboard No. 5 tank on November 13 completing the removal of fuel off the Rena.   Salvors will continue to remove any residual oil found in other parts of the vessel. It is believed that some 60 tons of oil may be trapped in the vessel’s keel.

Container Removal

The crane barge Sea Tow 60 took up position at the stern of the Rena and has removed a total of 95 containers from the vessel.   The containers can only be removed with good weather conditions.   Large swells or high winds cause the greatest risk to operations and have slowed the recovery process.   Some 220 transponders have been attached to containers that have either dangerous cargo or at risk of falling into the sea.  There are over 1100 containers still on board the Rena.

Environmental Recovery

Authorities have reported that 922 tons of waste has been removed from the area beaches.   Crews have used water blasting and washing rocks by hand along the rocky shorelines.   The wildlife facility is currently caring for 409 animals.   Over 2000 dead birds have been collected.

Editorial

The container vessel Rena has remained intact long enough to allow salvage crews to avoid an environmental disaster.   The Rena was predicted not to survive several storms after going aground on October 5 on Astrolabe Reef.  The vessel did suffer structural damage with several cracks along its hull, but has remained intact long enough to allow salvage crews to pump some 1000 tons of fuel off the vessel.   This is a great accomplishment for the salvage company and their employees.   However, the damage to the coastline has already been done.  Over 350 tons of oil was spilled from the vessel fouling the coastline around Tauranga, New Zealand.  Government and the private sector must be prepared for shipwrecks occurring anywhere in the world.

Pilot and Container Ship Collide

Pilot and Container Ship Collide

The 301 meter long, 78200 dwt container vessel Ever Strong collided with the 25 meter long pilot boat Duhnen on the Elbe Estuary off Cuxhaven, Germany.  The Duhnen was attempting to transfer the pilot to the Ever Strong in severe weather with 4 meter waves and wind gusts up to 88 km/hour.  The pilot vessel suffered damage to its bow and significant water ingress.  The pilot was able to board the Ever Strong while the crew contacted the DGzRS for assistance.  The DGzRS dispatched a lifeboat with pumps to the scene.  The lifeboat was able to keep the Duhnen afloat and escort it to Cuxhaven where local firefighters had pumps waiting.  None of the four crewmen on board the Duhnen were injured.  The Ever Strong suffered no damage and continued on to Hamburg.  No reports of pollution being released.

Angel 1 Sunk

The 197 meter long, 34,942 dwt freighter Angel 1 sank off Pointe-d’Esny, Mauritius after three months being aground on a coral reef.   Salvagers had made repairs and pulled the freighter free of the reef.  However, they found the hull had suffered many cracks.  These cracks enlarged as the vessel making repairs impossible.   Pumps barely kept the vessel afloat with it pumping out some 6,800 cubic meters per hour.   It was decided to tow the Angel 1 as far as possible from the coast and allow the vessel to sink.   When the vessel was some 36 miles off the coast, the crew was evacuated and the pumps were stopped.   The vessel quickly filled with water and sank.   The Angel 1 now rests under 4400 meters of water.   Reports state the Angel 1 still had some remaining cargo of rice on board.
