"EDT Hercules" leaves the shipyard

"La Naval" from Sestao (Spain) last ship 

Time elapses very quickly, more than we usually realize. Yesterday we saw the departure of "La Naval" shipyard's last ship, built there and named "EDT Hercules", and she is the last because there is no one behind to build ... until they get new contracts. This situation is similar to that which occurred about 8 years ago, when this historic shipyard, "La Naval", changed ownership from public Izar to private Construcciones Naval del Norte (CNN).

By that date, October 2006, the LNG gas carrier "Bilbao Knutsen" was launched,  and I put in my other blog a brief post on the launching, with a beautiful night photograph taken by my daughter Natalia. She was the last Izar ship but it was not the last "La Naval" ship, that continued building many ships, some very important.

Launching of ship “EDT Hercules” 

in La Naval from Sestao (Spain)

Ship type PSV for shipowner EDT from Cyprus

On  23th  July “La Naval” from  Sestao performed the launching of the ship “EDT Hercules” for the Cyprian group EDT  and her delivery will be made in the next spring, although previously she will be preceded by the one of her twin ship, presently  in the fitting-out quay.

The launching was normal although with the rare arrangement of being launched by the bow, due to the forms of the ship that are very fine at  the stern which would make it difficult her launching by this end as  is normally made.

Stability Calculation

(At preliminary stage of cargo ships design)

Introduction

Calculation of the stability is one of the basic and primary tasks that are to be done at the initial ship design stage, where it is not absolutely necessary to be quite exact, but where a quick calculation is very advisable, even if being approximate, allowing to analyze many alternative dimensionings in a short time. In this blog post I enclose a form where main cargo ship dimensions are to be input by the user and from them the program makes an approximate calculation and stability results are displayed for transverse metacentric height GM and righting levers GZ at several heeling angles.

Safe Return to Port

The event was held at the auditorium of the Bilbao Maritime Museum.

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.

 

 

"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.
