Propulsion - The future is Hybrid Electric

Von
ALL AMERICAN MARINE is constructing a new hybrid electric passenger vessel. The future is electric! 
Electric hybrid propulsion is quickly gaining momentum in the passenger shipping industry, especially with the announcement of HURTIGRUTEN’s world-first hybrid electric cruise ships, followed by other expedition cruise operators, who do not want staying behind, being "filthy".
by Earl of Cruise
The impact of diesel and marine oil polution on human health is without doubt, as it is the same for the global climate. Especially in sensitive areas, as the Artic regions. But sometimes is the media a bit too populistic with their articles and beat "only" on cruise vessels, whereas the freighters are not recognized.
I am aware of the air polution problem and have a great interest in green technology.

Electric propulsion is one of the buzzwords in passenger shipping right now. Indeed, HURTIGRUTEN chief executive Daniel Skjeldam emphasised the importance of electric propulsion, especially for expedition cruising, especially in the Arctic, at the recent Seatrade Cruise Global in Miami, USA.
He "bluntly" told delegates at a panel discussion on expedition cruising: “The future is electric.”
HURTIGRUTEN is building two hybrid battery expedition cruise ships at KLEVEN VERFT in Norway. ROLLS-ROYCE is providing new and environmentally sustainable hybrid technology for them.
ROLLS-ROYCE designed ROALD AMUNDSEN and FRIDTJOF NANSEN will incorporate, in addition to the hybrid power solution, the latest automation and control systems including the ROLLS-ROYCE Unified Bridge, the first delivery of two Azipull propellers using permanent magnet technology, two large tunnel thrusters, stabilisers, four Bergen B33:45 engines, winches, and power electric systems.
Mr Skjeldam said: “We think we will take the technology and the industry forward. They will be the most technologically advanced ships that are out there. The expedition industry needs to develop away from using 50-60 year old ships and find new technology that really reduces emissions. That is one of the most important things, when we sail in the most sensitive areas in the world. They are the most innovative and sustainable ships out there, taking what has been learned from battery ferries in Scandinavia and putting it into these vessels.”
He said that they were putting aside extra space in the world-first hybrid expedition cruise ships in order to be able to install even more battery packs, as the technology becomes more available. Mr Skjeldam said: “This technology is going forward very fast.”
Another hybrid battery passenger vessel contract has been confirmed as US shipyard ALL AMERICAN MARINE (AAM) recently inked a deal for the construction of a new hybrid electric passenger vessel to be delivered to RED AND WHITE FLEET of San Francisco. The contract for the new 600-passenger aluminium monohull was signed at the Passenger Vessel Association’s annual convention at MariTrends. RED AND WHITE FLEET will receive its new craft in late spring 2018.
The new vessel, to be christened ENHYDRA, will be the first aluminium hulled, lithium-ion battery-electric hybrid vessel built from the keel up under United States Coast Guard subchapter-K passenger vessel regulations and the latest guidelines for structural fire protection, AAM said in a statement.
AAM partnered with BAE Systems to design and integrate the complete battery-electric hybrid system. BAE Systems will supply its HybriDrive propulsion system that includes a generator, a control system, and an AC electric traction motor. The generator will mount to a variable speed Cummins QSL9 diesel engine delivering 410 mhp at 2,100 rpm. The motor generator offers diesel-electric operation of the AC traction motor which is coupled directly to the propulsion shaft. AAM said "With this configuration, torque is immediately available for the propeller and the speed can be controlled precisely without the need for a reduction gear."
The hybrid system will also use battery power from two 80 kWh lithium-ion battery packs. The batteries will come from Corvus Energy and are supplied under their next generation Orca ESS energy storage system line. The BAE HybridDrive system can automatically use full electric battery operation at slower speeds and when manoeuvring in and out of the harbour. At higher speeds, the generator will automatically engage and augment the additional power demands of the traction motor.
RED AND WHITE FLEET’s vice president of operations Joe Burgard, said: “We see the propulsion configuration on ENHYDRA as phase one in our move toward the full electrification of our fleet. Stay tuned for phase two.”

Meanwhile, FJORD1 has struck a contract with Norwegian Electric Systems for hybrid-electric systems for three new ferries being built by HAVYARD SHIP TECHNOLOGY.

Two of the ferries will operate the route between Brekstad and Valset and one ferry between Sandvikvåg and Husavik. The Norwegian Public Road Administration’s strict emissions requirements for these two ferry routes have resulted in an electrical propulsion system using chargeable lithium-ion batteries (lithium). The ferries are being designed by Multi Maritime.
Norwegian Electric Systems’ DC system ensures the safe charging and discharging of the batteries. It includes the Odin’s Eye solution, which Norwegian Electric Systems says is “an ultra-fast acting safety solution which is incredibly flexible, too. It provides for future upgrades of the vessels, such as larger battery capacity or higher charging power from shore.”
“We have had good and close contact with Fjord1, Havyard and Multi Maritime during this preliminary process,” said Norwegian Electric Systems vice president for sales Stein Ruben Larsen.
Norwegian Electric Systems will deliver a complete integrated DC grid system consisting of:
  • the Quest Energy Storage System (batteries)
  • DC switchboards
  • generators
  • transformers
  • switchboards, 230 VAC
  • quadro drive low loss DC/AC and AC/DC
  • Odins Eye, EMS and IAS
  • project management
  • calculations and engineering
  • commissioning and sea trials

    Stephen Carey Except that four Bergen B33:45 engines does not make it an electric ship. Had the same stuff years ago when the Navy was promoting its "all electric ship" to which I replied "You mean diesel/electric?". Well, they've got that ship now and it's the Type 45 destroyer which, whenever they have a problem with the propulsion train, the whole ship blacks out.
    I'm all for saving energy and being green, but I fail to see how batteries - which are not as efficient as a diesel engine - can be said to be greener as they require more energy to charge them up, provided by a diesel engine or other fossil fueled prime mover, or the national grid which is itself driven by fossil fuels. There is no way you can get a battery powered ship any other way. Same with the Tesla car (I'd love one of those) - it still needs charging up by using a source that is provided by fossil fuels. Until someone provides a hydrogen car or fuel cell, then it's not going to happen, and even then the hydrogen and the fuel cell will require manufacture by current means..

Ocean Liners in Movies or Films at Sea (updated Nov 2017)

Von
For liners and the shipping companies movies and films had been a top marketing tool Movies or Films and liners at sea, had been intriguing me since I have read about in my youth in LUXUSLINER - BILDER EINER GROSSEN ZEIT by Lee Server ( THE GOLDEN AGE OF OCEAN LINERS ). But earlier, mot only since my first crossing, I was keen watching movies with liners in it, and disapointed, which was an understatement, when I realized the films have been made in a set ashore in some movie "factory". That was after my first crossing.   by Earl of Cruise an essay in progress `Sabrina´, Humphrey Bogart in the office, while LIBERTÉ is sailing out of New York harbor - screenshot Ocean liners, especially those of the luxury category, had been the location of dramas, love stories, thrillers, suspense and catastrophies sinde film was born, or nearly.

Liners - Can classic ocean liners make a comeback

Von
Classic ocean liners, crossing the oceans, had been for long time the only way to cross the seas. A comeback of ocean liners for real? When in 2010 the Islandic volcano Eyjafjallajökull did errupt, and all flights that would come near his ash-clouds had to be cancelled, people had been trapped on each side of the pond ... And immidiately all available cabins on containerships had been booked, cruise vessels sailing either to the Americas or Europe had been flodded by desperate travellers to get to their destination ... Going by ship was in those days the only way to cross. It did show a certain, but temporary neccessity of liner traffic. But unfortunately we did not have any longer a frequent crossing possibility by ship - Transatlantic liners, liners per se had gone, gone with the wind of history and technical progress in air flight.

Heritage - Voyage of the Damned on St.LOUIS

Von
St.LOUIS sailed in May 1939 with Jewish refugees to Cuba, a voyage known today as the VOAYAGE of the DAMNED. On May 13, 1939, the German liner St.LOUIS sailed from Hamburg, Germany, for Havana, Cuba. On the voyage were 937 passengers. Almost all were Jews fleeing from the Third Reich. Most were German citizens, some were from eastern Europe, and a few were officially "stateless". Basicly the journey was a fraud, set up by sinister Propaganda Minister Josef Goebbels and his staff, to showcase nobody is interested in wanting Jews among them ... and till a seeming bitter end the free countries played in the Nazis directed game as they wished ... by Earl of Cruise based on Holocaust Ecyclopedia´s article St.LOUIS, sister ship of MILWAUKEE, were motorships of HAMBURG AMERIKA LINIE which served on different lines for HAPAG, as well on cruises - collection Earl of Cruise The majority of the Jewish passengers had applied for Cuba tourist visas and US immigration vi...

The modern Black Gang

Von
Stewardesses and Stewards are the modern " BlackGang " by Earl of Cruise  Stokers on board USS MASSACHUSETS - source Wikipedia The men working in the bowels of the steamers had been named Black Gang. these where those men with the hardest labour - bringing the coal form the bunkers to the furnasses and filling them. This ardous labour became obsolete, when the steamer and turbine furnasses became oil fired - cleaner, fewer men and no longer heat and coal dust drenched air. The living conditions, when free from their shifts, had been similar ardous - cramped sleeping rooms, no light and less air, and few washing rooms and toilets. The loan was less than acceptable. Despite some some first class travellers made their way in these aereas, as into third class, to "slum a bit", for whatever their reasons may have been, or tipping the men of the Black Gang for harder work making a fast voyage.

What had happend on sinking LA BOURGOGNE? Why had been so few women and children been rescued ? by João Martins , editing by Earl of Cruise ss LA BOURGOGNE - editors collection From our viewpoint of today we see this disaster of ss LA BOURGOGNE as one of egoism and the right of the stronger, with no "heroism", or stepping back for the weak to be saved. And we blame the crew for not doing their duty ... Are we allowed to judge? Are we allowed to chide? Are we alowed to claime it as typical ... for the seamanship of France - I have heard and read so! - ?  No, we have not been on board.  This tragedy is not the place to be chauvinistic! And looking in todays world we see a lot of chauvinism again and egoism! The ss LA BOURGOGNE was a 7,395 GRT French ocean liner built by the FCM in Toulon for the Transatlatic mail and passenger service of Cie. Gle. TRANSATLANTIQUE and completed in 1886.

HISTORY - The Royal Mail Ship TAHITI

While researching for some Tahiti and French Polynesia related articles, I came across this Wikipedia article about a small, lesser known steamship, which served as a "mail boat" in the South Pacific - rms TAHITI . editing by Earl of Cruise Beside the big liners on the main routes, especially the North Atlantic, on "side routes", which had been and are important for the international trade, we find countless numbers of ships. These smaller, unimpressive ones are the back-bones of each shipping entity. Most of these vessels had been combined passenger and freight liners - so PORT KINGSTON, later TAHITI.
