• The sea, one of the basic elements of the environmental balance on this planet, is under serious risk as a result of the pollution .

• An important part of the contamination has its origin in ships.

• Ships are enforced to fulfil certain rules to prevent pollution. These rules must procure to minimize the marine contamination.

Emissions to the atmosphere depending on naval propulsion type

► Use of High Efficiency Waste Heat Recovery (WHR) systems Total efficiency of the engine can be increased by more than 5 %. That means less fuel consumption and

therefore less emissions to the atmosphere.

Requires extensive modifications for existing vessels.

• The use of hazardous materials should be minimized in the design, construction and maintenance of ships. There is a need to prepare ships for recycling in such a manner as to reduce environmental and safety risks and health and welfare concerns.

• Adopts the IMO Guidelines on Ship Recycling set out in the annex of the resolution.

• Invites Governments to take urgent action to apply this Guidelines.

• The Guidelines seek to: – Encourage recycling as the best means to dispose of ships at the end of

their operating lives.– Provide guidance in respect of the preparation of ships for recycling and

minimizing the use of potentially hazardous materials and waste generation during a ship´s operating life.

– Foster inter-agency cooperation.– Encourage all stakeholders to address the issue of ship recycling.

SUSTAINABILITY OF SHIPS SCRAPING. RECYCLING

September 2002, Canary Islands

During National Navy Exercise Neotapón 02, 14 Beaked Whales stranded.The Spanish Ministry of Defence decided to fund any research aimed to find the causes of the stranding and the death of the animals.

•MARINE MAMMALS PROTECTIONMARINE MAMMALS PROTECTION

A group of patologists from the University of Las Palmas (Canary Islands), leaded by Dr. Antonio Fernández, claimed the corpses of the dead beaked whales and started a research based on the analysis of the tissues.

They discovered “holes” on the tissues and rised the theory of Gas Bubble Formation.

According to this theory, the beaked whales might have died because of Decompression Sickness.

•MARINE MAMMALS MARINE MAMMALS PROTECTIONPROTECTION

Further research was performed by NURC and other agencies. The unknown undersea life of beaked whales was researched. Some animals were “tagged” with sensors.

Sensor Tags showed an uncommon diving profile: they dive up to 1600 mts !.

That cleared the way for the Decompression Sickness Theory.


However, there was the scientific common belief that Marine Mammals, after million of years of evolution, cannot suffer from decompression sickness.


A tissue analysis on beaked whales stranded January 2006 in southeast Spain confirmed the Decompression Sickness Theory.

Spanish Navy Marine Mammals Protection Procedures

•Active Sonar activities cannot be performed within 50 NM of the Canary Islands.

•Before any active sonar exercise there must be a visual search for Marine Mammals in the area.

•If Marine Mammals are sighted, the acoustic transmission must be ceased until the area is clear of MM.

•When feasible, Passive Acoustic Search should be conducted before an active sonar exercise.

•Set sonars to minimum Tx power.

•Visual inspection of the area after the exercise.


Spanish MoD Present and future in relation to MM

SP MoD is preparing a new Research Agreement to be signed for cooperation with the Canary Islands Regional Government and the SP Environmental Ministry funding new research on Marine Mammals Protection.

SP Navy is involved in:• maintaining a Marine Mammals Sighting Data Base.• scientific cooperation with NURC for Cruises and research.
