A model of sailing vessel "Tuiga"

In my post from January 14 this year I presented several ship models built by Juan Ignacio Argaluza, who is an expert ship models craftman, what can be appreciated by looking at the pictures of his creations, although it´s not the same as seeing the actual models , in order to appreciate the extraordinary detail and accuracy of its components.

Lloyd's Register's 250th anniversary

Lloyd's Register is a ships classification society widely known in all marine shipping areas, which this year is celebrating its 250th anniversary, so I join the chorus of congratulations from the whole maritime family with my wishes they continue working for many years in their usual fields, and in those that technological progress will gradually be opening.

 

 

"Oliver Design" at Basque Television (Euskal Telebista)

Euskal Telebista (ETB), the Basque TV society, has issued on July 31 and August 1, within his channels ETB1 and ETB2, in Euskera and Spanish respectively, as a part of his Kresala program, a report about the ship design firm  "Oliver Design", of my friend and colleague Jaime Oliver.

"La Naval" from Sestao (Spain) launched the dredger "Charles Darwin"

Even with a bad weather a launching is always a cheerful event, it is a birth, a new vessel begins to live in her natural enviroment. This is what happened on Friday June 11, when the shipyard "La Naval" from Sestao (Spain), belonging to CNN group, made the launching of the suction dredger "Charles Darwin" for the Belgian company Jan de Nul, under an incessant rain that did not stop a moment during the launching and while having a drink afterwards at the  purposely fitted tent near the general offices.

Ships to install offshore wind generators

The European Union has plans to expand electric production by wind turbines up to 20 percent of total production in 2020, Spain being one of the leading countries in installed capacity of such generators located onshore.

Recently they have begun to install wind turbines at sea in areas up to 200 miles offshore and at not excessive depths, outstanding this kind of parks in North Sea countries. These "off-shore" generators solve some of the problems arising onshore, as noise, visual aesthetics, environmental opposition, and they get too a better use of wind power, which is greater at sea than onshore, and also allow for larger power / sizes, with better economic performance.

Merchant ships preliminary dimensioning

In the form that appears below the user indicates the type and size of a merchant ship whose main features wants to know and getting in response, a preliminary approximation of the same.

This estimate is based on statistical analysis and regressions (Ref.1) of ships dimensions, being actual ships or  designed projects, linking each of the characteristics of the ship with a single parameter describing her size ( deadweight, cargo volume, number of containers etc.). The resulting characteristics should therefore be considered as a first approximation only, which will give an idea of the characteristics of the new project or will serve as an initial basis for a more detailed definition by usual design procedures (Ref.2).

Estimating Ship's Gross Tonnage

On a past post I explained a simplified method to do an aproximate estimation of a ship's gross tonnage and an exact calculation of the compensated gross tonnage. Herein I enclose a simple input form to enter ship's main dimensions that produce results as explained in the mentioned past post.

If you know the actual gross tonnage just input its value in the text box (cyan color), and click button "Calculate". If you don't know the actual gross tonnage, input ship's dimensions and click "Calculate"

La Naval de Sestao entregó el buque Simon Stevin

Prototipo de buque tipo "Fall pipe"

En mi nota  de 5 Abril 2009 en este blog informaba sobre la construcción en La Naval de Sestao del buque 'Simon Stevin', del tipo "fall pipe", cuya misión es doble, por una parte depositar ordenada y precisamente piedras en el fondo del mar para obras de protección de cables y tuberías submarinos y para construcciones en plataformas de perforación y obras marítimas en general, y por otra parte, extraer minerales del fondo marino.

En esta foto se ve este buque en el muelle de La Naval  días antes de su salida hacia el dique.

 

Ship models from Juan Ignacio Argaluza

In my post of 10 April 2008 in this blog I wrote a note about the historic racing yacht Hispania, recently rebuilt at Astilleros de Mallorca, recovering an authentic jewel of sport shipbuilding, of true both technical and historical interest.

A few days ago I was phoned by  Juan Ignacio Argaluza, Getxo's neighbor like me, whom I did not meet before, informing me that he was building a model of the sail yacht Tuiga, twin of Hispania, and having read my blog note he had got an interest in commenting to me on some respects . A few days later I visited him at his home and he showed me the model of the Tuiga's hull , under construction, and told me he was finding some problems due to lack of ship's drawings that will guide his work.
