MAJOR PROJECTS / BERNARDO HOUSSAY VESSEL
The Research Vessel Dr. Bernardo Houssay was built, modernized and completely redesigned in CINAR.
Originally built in Denmark between 1929 and 1930, the vessel served for CONICET on oceanographic research tasks for over 40 years until 2001 their domain is transferred to the Argentinean Cost Guard and renamed Dr. Bernardo Houssay. On board this yacht sailed, among others, the Danish August Krogh and the Ukrainian Selman Waksman awared with the nobel prize of Medicine in 1920 and 1952 respectively; as well as the legendary Jacques Cousteau.
RECONSTRUCTION, MODERNIZATION AND REDESIGN OF VESSEL DR. BERNARDO HOUSSAY
To carry out the activities inherent to its function for the argentinean Coastguard a reconstruction and redesign of the shipwas necessary, due to heavy wear-off suffered by the passage of time and obsolescence of technology possessed for navigation and scientific research. Bearing that in mind, a process of reconstruction, modernization and expansion was decided which lasted more than three years.
The Dr. Bernardo Houssay Research Vessel enters CINAR workshops on January 15, 2005, for a complete reconstruction and modernization of its structures. To do so this the ship was completely redesigned andentire sections of it, such as the bow and stern, were built entirely in Almirante Storni facilities and replaced.
The propulsion engine, generators, sails, masts, toiltets , capes, propeller, dinghy, survival kits, purifying system for drinking water,effluent plant treatment, aire conditioning system Replaced , pipes and electrical panels were replaced.
After modernization, Bernardo Houssay can carry up to 30 scientists with capacity to conduct research because its redesign incorporated a wet lab with its own cold storage and a dry laboratory. For this purpose,the demands of scientific and technological knowledge and the recommendations made by prestigious Argentine and foreign researchers in the various scientific disciplines related to the study of the oceans were taken into account.
WATER FLOW CONTINUOUSSYSTEM
The vessel was equipped with a continuous flow of water that will go from a water intake in the keel to the wet lab, which has temperature, conductivity, fluorescence and dissolved oxygensensors, among others, in order to be able to record georeferenced information 24 hours a day.
In addition an oceanographic rosette with capacity for several bottles was incorporated. This gadget takes water samples at different depths for physics, chemical and biological analysis. The rosette incorporates a CTD, a sensor for conductivity, temperature and depth that will engage dissolved oxygen, chlorophyll, hydrocarbons, fluorescence and turbidity sensors allowing to have real-time information on environmental variables in the water column to determine the depths to which water samples for analysis are taken.
An oceanographicwinch was also incorporated that will be used to deploy the rosette to the deep sea through a 2000 meters of an electrical conductor cable-way, which will study the water column above the platform on which the vessel navigates and the adjacent continental slope.
In addition, networks for sampling plankton micro organisms and macroscopic were installed. With these tools horizontal stratified tows in certain depths according to information provided by the echo sounder of the water column will be made.
Moreover as data of relevance the original draft of the ship had to be reduced by 120 cm, thus allowing it to navigate the Rio de la Plata without difficulty and a closer to coastal ocean waters to carry out pollution control and perform activities of scientific interest.
