The hybrid remotely operated submersible crushed in the Kermadec Trench


 The Nereus was the most capable research submersible in the world.  Built in 2008 by the Deep Submergence Lab at the Woods Hole Oceanographic Institute (WHOI), it was named after the Greek sea titan of the same name.  The mythological god had a man’s head and body and a fish’s tail.  The submersible was also a hybrid: it could operate autonomously to survey large areas of the ocean floor or it could operate in a thin tether to do precise analysis of small areas and recover objects and samples from the sea floor.  It could and did explore the deepest parts of the ocean, diving to the bottom of the Challenger Deep in the Marianas Trench (10,902 meters or 35,768 feet below sea level) on May 31, 2009.  Only the manned submersible Trieste in 1960 and the Japanese submersible Kaiko in 1995 had ever achieved this feat.  Nereus had also explored the world’s deepest known hydrothermal vents along the Cayman Rise in the Caribbean Sea.  Weighing approximately three tons, Nereus consisted of two four-meter long cylinders largely filled with precisely engineered ceramic spheres for floatation.  It also carried 2,000 lithium-ion batteries for power.  When operated as a remotely controlled vehicle (ROV), contact with the surface vessel was maintained via a slender glass fiber cable with a full length of 40 kilometers.  In April and May 2014, Nereus was engaged in the first systematic study of the Kermadec Trench in the South Pacific Ocean northeast of New Zealand.  Thirty days into a planned 40-day mission and seven hours into a planned nine-hour dive, contact with Nereus was suddenly lost by technicians on the support vessel Thomas G. Thompson.  Debris from Nereus was later recovered on the surface.  Analysis revealed that Nereus had suffered a catastrophic implosion resulting from the high pressures of the 9,900 meter depth at which it was operating.

Battle of Salamis


Jun 20, 2014, 7:00AM EST

The pivotal naval battle the saved western civilization for a millennium

 The Battle of Salamis was fought in September 480 BC between the warships of the Greek alliance and the warships of Persian Empire.  Following the land battle of Thermopylae and the sea battle of Artemisium, the victorious Persians moved down Attica and conquered the city-state of Athens, which had been largely evacuated.  The Persian King Xerxes was anxious to decisively defeat the Greeks, who had defeated his father Darius at the battle of Marathon in 490 BC.  He therefore pressed ahead with his plan to overwhelm the much smaller Greek fleet, then located in waters between the mainland and the island of Salamis.  Numbers of the opposing forces are somewhat in dispute, but the Persian fleet consisted of approximately 1,000 to 1,200 triremes, while the Greeks had approximately 370.  Upon hearing of possible dissention in the Greek ranks, Xerxes ordered his fleet into the confined waters.  The Greeks, though, were unified in their opposition to the Persian invaders and were more experienced ship-handlers.  The Persian vessels got in each other’s way, making a coordinated attack impossible.  The Persians were decisively defeated, losing about 80% of their vessels and crews.  Xerxes soon withdrew the bulk of his forces back to Asia Minor, leaving a relatively small occupation army.  These remaining soldiers were defeated the next year in the battle of Plataea.  The Persians never again attempted to invade Greece.  If the Persians had prevailed, western civilization would look much different.  Europe was not successfully invaded again by Asian forces until it was attacked by the armies of Genghis Khan in about 1220 AD.  The major lesson of the Battle of Salamis is that one should never underestimate your opponent, particularly when that opponent is defending the homeland.  


Oι ΗΠΑ αναγνώρισαν "τουρκική" μειoνότητα στην Δ.Θράκη!


Mια συνάντηση που προοιωνίζει αυτό που ετοιμάζουν οι ΗΠΑ στην Δυτική Θράκη, πραγματοποιήθηκε την περασμένη Τρίτη στην Θεσσαλονίκη του πρόξενου των 
ΗΠA στην...
πόλη, Ρόμπερτ Σάντερς και της ηγεσίας του εξτρεμιστικού μειονοτικού κόμματος Ισότητας Ειρήνης και Φιλίας (DEB) το οποίο συμμετείχε για πρώτη φορά στις ευρωεκλογές κερδίζοντας την πλειοψηφία στους νομούς Ξάνθης και ροδόπης και έχει ως σημαία του την κατάργηση της συνθήκης της Λοζάνης και την τουρκοποίηση όλων των μουσουλμανικών πληθυσμών της ελληνικής Θράκης.!

Η συνάντηση των ΗΠΑ και των ισλαμιστών πραγματοποιήθηκε μάλιστα μετά από πρόσκληση του Ρ.Σάντερς και έγινε γνωστή, με ανακοίνωση που ανήρτησε στην ιστοσελίδα του το DEB (από όπου και η φωτό)! Και σίγουρα οι ισλαμιστές δεν θα έδιναν την φωτογραφία στην δημοσιότητα αν δεν ήθελαν οι Αμερικανοί.

Στην ανακοίνωση των ισλαμιστών αναφέρεται ότι: «Επιτροπή του DEB αποτελούμενη από τον πρόεδρο Μουσταφά Αλή Τσαβούς, τον αντιπρόεδρο και υπεύθυνο Ξάνθης Οζάν Αχμέτογλου, τον υποψήφιο ευρωβουλευτή Ονούρ Χιντ και την υποψήφια ευρωβουλευτή και διευθύντρια διεθνών σχέσεων του κόμματος Λεϊλά Σαλίχογλου συναντήθηκαν με τον Αμερικανό πρόξενο Θεσσαλονίκης Ρόμπερτ Σάντερς και με άλλους διπλωμάτες. Στην συνάντηση με τους Αμερικανούς διπλωμάτες τέθηκαν τα θέματα και τα αιτήματα της τουρκικής μειονότητας δυτικής Θράκης, η επιτυχία του DEB στις ευρωεκλογές και οι εργασίες του κόμματος».

Τι σημαίνει η παραπάνω συνάντηση; Πολύ απλά ότι οι ΗΠΑ αναγνωρίζουν εμμέσως πλην σαφώς ότι η μειονότητα είναι τουρκική. Κατά δεύτερον λόγο "αγκαλιάζουν" τους ισλαμιστές της Θράκης, όπως ακριβώς αγκάλιασαν τους ισλαμιστές της Συρίας και "χαϊδεύουν" την Μουσουλμανική Αδελφότητα στην Αίγυπτο.

Ουσιαστικά εμμέως πλην σαφώς τάσσονται υπέρ της κατάργησης της Συνθήκης της Λοζάνης. Μόνο που η συνθήκη της Λοζάνης δεν αναφέρεται αποκλειστικά σε θέματα πληθυσμών, αλλά καθορίζει και την εδαφική κυριαρχία Ελλάδος και Τουρκίας στα σημερινά τους όρια και αποτελεί πάγιο πολιτικό στόχο της Αγκυρας η κατάργησή της, ειδικά σε ότι αφορά το ιδιοκτησιακό καθεστώς των νησιών του Αιγαίου.

Κάτι που δήλωσε ευθέως και ο Τούρκος Αρχηγός του Γενικού Επιτελείου πριν δύο ημέρες (μόνο το defencenet.gr μετέδωσε την πολεμική δήλωσή του).

Μάλιστα της συνάντησης ακολούθησε και δεξίωση που παρέθεσε το Προξενείο των ΗΠΑ στην Θεσσαλονίκη, "προς τιμήν εκπροσώπων φορέων και οργανώσεων ανθρωπίνων δικαιωμάτων της Βόρειας Ελλάδας".

Θα το ξαναπούμε: Το ισλαμικό τρένο έρχεται με ταχύτητα και οι ΗΠΑ ρίχνουν καύσιμο στις μηχανές του...

Training to Prevent Marine Accidents & Deaths

...indeed to be a seaman is not an easy task, and the last 20 years has been tougher.
Yes, knowledge , skill and attitude is a must, but are not enough.
During a voyage of 15-30 days, everything runs smooth, and am not speaking for colissions etc, the any problem appears when the ship arrives to port, where regardless its size, completing loading or discharging in 2-4 days.. Can anyone imagine the stress conditions the crew involved?? fatigue is one, and think that can be 2 ports for loading or discharging. Then what??
The fact that crew is dreaming to go ashore after a long period cannot be forgotten. So, many and various things are keeping busy the mind, redirecting the crew from their work, and this is normal.
If you go back, when ships where staying longer times at ports, was no obvious problems. Since many years now , have put the industry in concern, and what bothers me is that after deaths occured we see the problem...... Knowledge and skill are not the medecine only... unless if you are looking for macines.....

Reducing accidents depends on knowledge, skill and just as importantly, attitude, says the Indian Maritime Administration. And, human error is not always just seafarer error.
  
As the government of India strives to raise India’s share of the global seafaring community from 7 to 15 percent by 2020, at the same time, it struggles with the reality of an escalating death rate attributed to accidents and suicides among Indian mariners. According to the casualty figures released by the Directorate General of Shipping, government of India (the Indian administration) there were 25 accidental deaths, 2 cases of suicide and 8 sailors reported missing during 2012. Year to date data in 2013 suggests a similar and perhaps even slightly elevated pattern.  
Since human factors are said to account for 80 percent of marine accidents, one of the administration’s many motivations for reversing the trend is that the inherent dangers are a deterrent to youth who might otherwise want to enter the seafaring profession. According to Gautam Chatterjee, the Director General of Shipping (DGS), who heads the Indian Maritime Administration, much depends on competence of the seafarer for reducing accidents. In his address on the National Maritime Day he also insisted, “For competence, one needs knowledge, skill (that is hands-on proficiency) and attitude. So in order to reduce accidents at sea, all these three aspects need to be targeted.”

Causes & Remedies

The faster turnaround of ships resulting in very short port stays and reduced opportunities to undertake maintenance of deck and machinery has, over time, brought tremendous pressure on seafarers. As seafarers hurry to complete work within a limited time frame, they also often end up getting injured. A new system, put into place for curtailing accidents, begins at the time of selection itself, wherein only the right candidate is allowed to register for training. The DGS has fixed norms for eligibility for candidates, including but not limited to minimum qualifications and psychometric tests. Beyond this, Behavior Based Safety Courses are being conducted for both pre sea and post sea levels.
“In order to reduce accidents, Anglo Eastern conducts various value-added courses to address knowledge and skill,” said Captain Kersi N. Deboo, Director & Principal of the Anglo-Eastern Maritime Training Center, a well-regarded India-based maritime training institute offering a large number of pre-sea and post-sea curriculum. He added, “Courses must be current, up-to-date, topical and with practical hands-on training. Because statistics indicate that 80 percent of accidents happen due to human error, we have introduced a number of courses to address the attitude and the behavioral aspects of error management / preventing accidents. We have a set of safety related courses which address occupational hazards, risk assessment and incident investigation. Further, we have a number of courses that address the behavioral aspects of behavior-based safety, maritime resource management, leadership and team work.”
He also points out that all these courses are incorporated in the recent revision of STCW 2010 where additional elements have been included at all levels of resource management, leadership and team work. After recognizing that attitude and behavior play a dominant role in reducing the cause of accidents, Anglo Eastern became the first training institute in India to introduce these requirements, well prior STCW 2010 coming into force. The 2010 amendment has made it part of the competency syllabus and are more of soft skill training.
“We conduct the courses at various levels,” says Capt Deboo. “We have occupational hazards, risk assessment, safety inspections and also maritime resource management and behavioral based safety at all levels. Besides, incident investigation and leadership for the senior level officers there are number of workshops based on case studies, experience sharing, role play and simulation exercise.”

Turning Knowledge into Policy – and everyday practice 
Anglo Eastern says it all boils down to how much of the learning that takes place ashore is adapted on board. Shipping companies therefore need to develop a mechanism to monitor activities on board the ship, while also making senior officers accountable for developing a professional safety culture on board. This involves adequate preparations for every possible scenario. For example, port calls entail pre-arrival work, the inward passage, followed by cargo activities, port state inspections, agents, vetting, and a dozen more necessary tasks. Separately, ship’s engineroom staff has to perform maintenance on the power plant – all within a very narrow time frame. In other words: a stressful time where a large percentage of accidents are known to occur. 
“Working under stress, seafarers are often pushed to work quickly,” says Captain Deboo. “Doing things fast without adequate rest leads to seafarers taking shortcuts or bypassing certain functions. This ultimately leads to mistakes. A thorough understanding all the equipment and the skill to do the job is of course necessary. So, too, is the right attitude, particularly the “buddy factor” – that is everybody working as a team; sharing the work load or warning somebody about any imminent danger or action that will lead them to harm.”

Human Error vs. Seafarer Error

Captain Yashoverman Sharma, Head of Training, International Maritime Training Center (Wilhelmsen Maritime Services), takes a holistic view. “It is wrong to assume that human error, which is associated with 80 percent of accidents at sea, is the same as ‘seafarer’ error,” he contends. “In fact, in my assessment, human error is 99.9 percent of the cause of accidents. Typically, losses suffered in any accidents at sea are considered in ‘dollar terms’ and human lives hardly factored into the equation. This is sad. On the contrary, everything else should be sacrificed to save human lives. In reality, this is rarely the case.” 
Sharma insists that by assuming ‘human error’ being solely ‘seafarer error’ has led to the incorrect assumption that training (alone) can put an end to accidents. “But, I am sorry to say that it is not so,” he emphasizes. “They have identified human error as the critical issue and training programs are being revised to help the operators to reduce accidents. I am not saying this is not useful. It is very good. But I want to point out that eventually, the circumstances of the conditions under which such incidents take place involves more people than just the seafarer on the spot. These people are the ‘behind-the-scene’ operators.”
But then what is human error, he asks. Sharma points out that it is humans who make rules. If it happens that the port state control and flag state don’t do their duty well, then that too becomes human error. If the engine fails, leading to loss of life or property then that too becomes human error as the engine was designed by humans.  “Why should we equate human error to seafarer error alone?” he asks. “If I say the seafarer was fatigued and therefore his judgment was impaired leading to a collision or injury to himself, I would say that instead of falsely implicating the seafarer one must ask, ‘What about the people who put the seafarer in that position where he ends up getting fatigued?’ Shall we say that it is the company which should have seen that there were more hands on board or the administration that should have brought into place necessary preventive regulations? Or is it possible that the ship board management was responsible? There are so many possibilities.”    
Sharma contends that very few accidents are really solely attributable to the lack of knowledge or skills. Furthermore, he says, every seafarer is under the threat of being blamed for the ship being delayed or the owner facing losses or the ship machinery or equipment gets damaged. So, he says, with the best of intentions people are driven to cause accidents.  According to Sharma, in any incident, before one assigns blame, it is necessary to see what created that accident. Under what conditions was the vessel being operated? Often the conditions under which seafarers have to work are not entirely under their control. Was it lack of spare parts, improper machinery and no money from the owner?
“I am not saying that the shipowners who spend all the money on training and maintenance of the ship do not experience accidents; there are accidents still happening,” Captain Sharma says, “The best of companies have faced marine disasters. It is a matter of reducing risks that is important. It does not end only with issuing instructions to the ship. There needs to be support as well. I say one must delegate more powers. If proper responsibility is given and conditions created for operating the ship safely, then accidents will reduce.”
Sharma had more to say. “Accidents which are assigned to the human element cannot in my opinion be attributed to seafarers alone. It also involves the operators and working environment they have created on the ship, the designers of the ship, the naval architects, etc. Unfortunately, ship designers don’t typically sail on the ships that they design. It is found that many accidents resulting in injury or death to seafarers could have been avoided if care had been taken to integrate safety measures while designing the ship. Even in the administration, accountability is lacking. People survey ships and make it pass all safety tests. Should I say the surveyor did his job in the case of MOL Comfort?  Did he ensure that it would not break into two?”
 

Safety: Everyone’s Business 
The takeaways from the foregoing discussions are clear. Of course, competence, knowledge, skills and attitude are primary ingredients of a safe and productive merchant seafarer.
At the same time, all of that can count for little if the mariner is placed into poorly designed physical surroundings, impossible situational scenarios, and with inadequate engagement from above and ashore.
It turns out that safety does come from the top: from the superior officer(s) on board, ship’s management ashore, the ship’s design team, the flag state and the classification society, too. The introduction of STCW and its many amendments is just one piece of the puzzle. Likewise, training alone will not prevent accidents from happening. And, until that reality is embraced by the full chain of personnel involved with today’s intermodal transportation chain, the inevitable accident will remain the rule, rather than the exception.

Ιταλοί θέλουν την ακτοπλοϊκή σύνδεση «Βόλου-Σμύρνης

....πέστε μας και πόσο στοίζισε η μελέτη, για να έλθουμε στα ίσα...
Το 2013, θέλατε μελέτη για να καταλάβετε ότι ο Βόλος - Σμύρνη, είναι ο συντομότερος δρόμος διασύνδεσης με την  Ευρώπη?
Η μελέτη βιωσιμότητος, που κάνατε σημαίνει ότι έχει και οικονομικά στοιχεία. Γιατί δεν τα δημοσιεύετε, ωστε να διευκολύνεται τους ενδιαφερόμενους πλοιοκτήτες να βάλουν στην γραμμή τα πλοία τους?? Εσάς περιμένουν... τόσα χρόνια, που μόνο γλέντια με τους γείτονες είστε, έχετε κάνει σωρό μελέτες, αλλά μέχρι εκεί.
Εφ' όσον λοιπόν η γραμμή είναι καλή, και τα θέματα τα κετέχετε, γιατί δεν βάζετε εσείς ένα φέρυ να πηγαινοέρχεται?? να κάνετε και τις κρουαζιέρες σας, τι πιο εύκολο??
κόλον θέλει το ραπάνι...


limani_volos_aktoploiki_sindesi_
Ενδιαφέρον για την ακτοπλοϊκή σύνδεση του Βόλου με τη Σμύρνη επέδειξαν το τελευταίο διάστημα μεταφορικές εταιρείες από την Ιταλία, οι οποίες σε επικοινωνία με εκπροσώπους του Οργανισμού Λιμένος Βόλου (ΟΛΒ ΑΕ) δήλωσαν πως θεωρούν το ενδεχόμενο της σύνδεσης εφικτό, βιώσιμο και το εξετάζουν σοβαρά.
Το ενδιαφέρον των ιταλικών εταιρειών υπογράμμισε, σε δηλώσεις του στο ΑΠΕ-ΜΠΕ, ο πρόεδρος και διευθύνων σύμβουλος της ΟΛΒ ΑΕ Ιωάννης Πρίγκος, σημειώνοντας πως έγιναν επαφές για το θέμα.
Αυτή η εξέλιξη εκτιμάται ότι, δημιουργεί πρόσφορο «έδαφος» για την περαιτέρω συζήτηση της σχετικής πρότασης και της μελέτης του Οργανισμού Λιμένος Βόλου (ΟΛΒ ΑΕ) για την επίτευξη του προαναφερθέντος στόχου.
Ο ΟΛΒ εκπόνησε και ολοκλήρωσε -στο πλαίσιο της στρατηγικής του ανάπτυξης- τη μελέτη βιωσιμότητας για τη θαλάσσια σύνδεση Βόλου – Σμύρνης, τον περασμένο Μάιο, αναφέρεται σε σχετική ανακοίνωσή του.
Σύμφωνα με τη μελέτη, η σύνδεση Βόλου – Σμύρνης αποτελεί τη συντομότερη διαδρομή διασύνδεσης Ευρώπης και Ασίας, ενώ δημιουργεί και χερσαία σύνδεση με τα λιμάνια της Πάτρας και της Ηγουμενίτσας (πρωινή άφιξη στο Βόλο από Σμύρνη και νυχτερινή αναχώρηση από Πάτρα ή Ηγουμενίτσα προς Ιταλία και το αντίστροφο).
Παράλληλα, αποτελεί δίαυλο διακίνησης εμπορευμάτων προς κεντρική, ανατολική και δυτική Τουρκία, όπως και προς Ιράν, Ιορδανία, Σαουδική Αραβία και αλλού.
Η ίδια ακτοπλοϊκή σύνδεση μειώνει σημαντικά το χρόνο, ώστε τα πλοία να κάνουν περισσότερα δρομολόγια και τα κόμιστρα των φορτηγών αυτοκινήτων που μεταφέρονται με τα πλοία.
Επίσης, προσφέρει τη δυνατότητα χρήσης πλοίων RO–ΡΑΧ (συνδυασμένων μεταφορών) με αποτέλεσμα την αύξηση των κερδών λόγω της μεταφοράς επιβατών σε καμπίνες, στους οποίους θα παρέχονται διάφορες υπηρεσίες (καζίνο , duty free) και τα οποία θα μπορούν να εκτελούν και διήμερες κρουαζιέρες με μεταφορά τουριστών προς και από το Βόλο.
Πέραν αυτών, η ακτοπλοϊκή σύνδεση Βόλου – Σμύρνης προσφέρει, σύμφωνα πάντα με τη μελέτη – τη δυνατότητα εκτέλεσης εβδομαδιαίων κυκλικών κρουαζιέρων με προτεινόμενη διαδρομή: Πειραιάς – Βόλος – Θεσσαλονίκη – περίπλους Αγίου Όρους – Καβάλα, Τσανάκαλε – Κωνσταντινούπολη – Σμύρνη, ενώ εναλλακτικά ως λιμάνι αφετηρίας μπορεί να χρησιμοποιηθεί η Κωνσταντινούπολη.
