Mitsubishi Heavy Industries (MHI) signed on the dotted line a few days ago to build a 138,000 gt LNG carrier in their ‘Sayaendo’ series for Mitsui O.S.K. Lines .  MHI describe this 288m (945ft) long vessel as a ‘New-generation’ LNG carrier, with a multitude of new design features which add up, MHI claims, to deliver a 25% reduction in fuel consumption compared to that of conventional LNG carriers of the same size; but essentially the design is marked by two outstanding features. The first a dramatic change in the shape of the ship compared with the distinctive dromedary-like silhouette of other LNG carriers. Second a  new turbine plant that achieves higher thermal energy by steam reheat.

The ‘peas’ are the spherical LNG tanks, the ‘pod&r... [More]

Olympic & Sealandia – New Year Centenary Retrospective

New Year may excuse a look back a century in time to recall what was happening in our area of interest during the year 1911. It was a year worth remembering, one in which Sealandia, the first ocean-going cargo ship with diesel engine propulsion was launched, and in the same year Olympic set out on her maiden voyage with propulsion shared between the new-wave steam turbine and the steam reciprocating engine.Joseph Conrad described the modern passenger ship as, "A marvel of applied science on its technical side, and an unpleasantly unsteady imitation of a Ritz Hotel in its social atmosphere." Conrad, compelling nautical author and sailing-ship era master mariner recorded this impression in his 'Ocean Travel' essay after a transatlantic passage he made in the nineteen twenties. In their separate ways both Olympic and Sealandia exemplified two such marvels of applied science as Conrad had in mind.SealandiaThe 6,800 dwt Selandia, the world's first ocean-going ship propelled by a diesel engi...

Nuclear Power for Tanker Propulsion – A 'Work in Progress'

"We believe that as society recognises the limited choices available in the low carbon, oil scarce economy...  we will see nuclear ships on specific trade routes sooner than many currently anticipate." This prediction came from CEO Richard Sadler of British classification society Lloyd's Register as he announced membership of a new 'think tank' on 15, November 2010. Lloyd's Strategic Research Group has joined hands with a research consortium that aims to produce a practical concept design tanker fuelled by a 70 MW nuclear reactor, setting itself a two-year time-frame for the project. Other members are US-based Hyperion Power Generation, who are expert in small modular nuclear reactor technology; innovative British ship design group BMT; and Greek shipping conglomerate, Enterprises Shipping and Trading S.A. The consortium chose a tanker design for its initial project as nuclear power appears suited best for large deadweight vessels that are at sea for much of their time, but whethe... [More]
