Abstract:
During James Cook’s second voyage of discovery, a young Tahitian by the name of Omai (1751–1780) was taken aboard the Adventure, one of the two ships of this expedition. Omai travelled to England, where he was introduced into the British Upper Class and much admired as a living example of a noble and pure South Sea islander in tune with Mother Nature. Omai became accepted in the highest society circles, was painted by several great artists of the time and became part of the collective hype surrounding James Cook’s voyages of discovery and the new experiences with non-European cultures. This paper compares available scientific literature on this topic and aims to analyze the role of Omai as a historical figure and as the personification of the idealized European concept of the noble savage.

Abstract:
Although Thomas Jefferson had recognized the need for mapping and charting the waters of the young United States in 1807, it wasn’t until 1830 that the US Navy established the Depot of Charts and Instruments, which later became the US Naval Hydrographic Office. At the beginning, the Depot was a clearinghouse for navigational equipment and the few foreign charts that were available. The Depot didn’t make its own charts until 1837, with the first one covering Georges Shoal and Bank, from ship tracks provided by Lt. Charles Wilkes. Wilkes later led the famous 1838 US Exploring Expedition that provided the United States its first worldwide mapping coverage (Heynen, 1978).

Abstract:
This chapter investigates how blockade running from Nassau ran wild for most of the year, even with Seth Hawley and Charles Wilkes gone. It argues that the supplies continued to flow through Nassau in great quantities almost to the end of the war. With such an unprecedented opportunity to make money, the chapter looks at people of all sorts who began to take up residence in Nassau. Many of them lived at the Royal Victoria, a hotel that had been a speculative venture by the Bahamian government but was now bursting at the seams and staying full all year. It then presents the two interesting lodgers at the hotel: British naval officers Augustus Charles Hobart-Hampden and Charles Murray-Aynsley. These two, along with fellow officers William Nathan Wrighte Hewett (who would captain the blockade runner Condor) and Hugh Talbot Burgoyne, were granted furloughs to try their hand at running the blockade. The chapter also details the first vessel built expressly for blockade running and would be the first all-steel ship to cross the Atlantic — the Banshee. The chapter also displays some notable British citizens who passed through Nassau and found themselves doing business in the city.

Abstract:
I agreed to meet Punk Paul on Stokes Croft at around 8 a.m. Paul was exactly where he said he would be—behind the bin next to The Big Issue office. In his early forties, Punk Paul was everything a punk should be—a devout follower of punk bands across the UK, he sported a blue Mohican (when bathroom facilities and soap rations permitted), army issue boots and a battered leather jacket covered in ‘anti-fa’ (anti-fascist) symbols. Paul fashioned the rest of his clothes from whatever he was given by church volunteers and picked up along the way. His distain of authority was firm but friendly. ‘Evening officer,’ he could often be heard saying, with a wink, to local police who regularly busted him for drinking in ‘no drinking zones’. ‘Could you spare a few shekels for an old sea dog? I’m trying to get together a pirate ship to sail off the end of the earth!’ ‘I have to pay Abdul £10.03,’ Paul said, as I approached. Abdul, Stokes Croft’s kindly but long-suffering newsagent, let some homeless people, including Paul, have beer on tick. We walked the short distance from the post office to Abdul’s shop and I waited outside with my dogs while Paul paid his debt. He was holding a can of Tennant’s lager when he reappeared. ‘It’s sort of a constant debt that I have with Abdul!’ He grinned before leading the way down City Road, Brighton Road, and onto Wilder Street. ‘You have to see this place! If you want to see what homelessness is really like in this country . . . this city could be any city, if you ask me. You have to see this place!’ We continued down Wilder Street until we reached a semi-derelict building. Through peeling paint it was possible to read ‘Bristol Transmissions’ above the long-ago boarded-up shop window. ‘It’s known as “The Black House”,’ Paul said, pushing the door. A padlock had been smashed off. Inside, there were two downstairs rooms, both hugely decayed with missing floorboards.

Abstract:
This chapter describes a mosquito-borne illness, referred to as Yellow Jack by the sailors because of the yellow flag flown by quarantined ships, that arrived in Nassau during late summer. The chapter states that the blockade runner Kate also brought yellow fever with her to Wilmington, and by mid-August, the city was going through a devastating epidemic. The disease also found its way to Key West, Florida, and Beaufort, and Port Royal in South Carolina. As the fever raged in late July, the amount of shipping arriving and leaving Nassau dwindled to pre-war levels. The chapter then shifts to discuss a hindrance to the post-epidemic resurgence of the blockading bonanza — the appearance of Charles Wilkes, the US naval officer who had pulled Mason and Slidell off their boat. It elaborates the mission of West Indies Squadron, under the command of Wilkes, to destroy Florida and the new Confederate cruiser that had emerged from England with Raphael Semmes in command, the 290 (soon-to-be known as Alabama).

Abstract:
This chapter suggests that tenancy plays a major role in nineteenth-century detective fiction, an emerging genre that counted Dickens, Wilkie Collins, and Charles Warren Adams as enthusiastic early practitioners. The chapter starts by investigating the relationship between geography, class, and morality in contemporary social discourses, focusing on the ‘low’ or ‘common’ lodging house in London. Low lodging houses were widely associated with criminal behaviour, and Dickens and Collins were interested in the function they could perform in their fiction. The chapter moves on to examine the murders that take place in Bleak House, The Moonstone, and The Notting Hill Mystery, and argues that rented space becomes a tool in the battle between detective and criminal. The chapter ends with an extended reading of Krook’s lodging house and rag-and-bone shop in Bleak House. Here, a mystery narrative intersects with farce and the Gothic, attesting to the porosity between aesthetic forms.

Abstract:
This chapter reviews Thomas Kirkpatrick's arrival from New York to Nassau to fill the new position in state of the consulate. It states that Kirkpatrick entered the consulate and found the office in a chaotic state. In preparation for the move, Kirkpatrick was able to sit down with George Harris and discuss resolution of the back-rent issue and other debts incurred by the office dating back to the repair of the windows Sam Whiting had broken out. The chapter also elaborates John Howell's idea that would help the Union: to establish a coal depot for US merchant ships on Hog Island near the dry dock. US Marshal for New York City Robert Murray introduced Howell as a true friend of the Union cause, who had provided much information on blockade runners. The chapter then narrates the downturn in activity in Nassau two days after Kirkpatrick's arrival: the return of yellow fever in 1864. Ultimately, the chapter discusses Kirkpatrick's recruitment of a couple of spies within the blockade-running companies and the surge of shipping in and out of Nassau. It further analyses Kirkpatrick's call for a new flying squadron to come to the Bahamas and reactivate Charles Wilkes's idea of nipping blockade runners off at the source.

Abstract:
As part of WILS II (Wave Induced Loads on Ships) Joint Industry Project organised by MOERI (Maritime and Ocean Engineering Research Institute, Korea), Lloyd’s Register has undertaken time domain springing and whipping analyses for a 10,000 TEU class container ship using computational tools developed in the Co-operative Research Ships (CRS) JIP [1]. For idealising the ship and handling the flexible modes of the structure, a boundary element method and a finite element method are employed for coupling fluid and structure domain problems respectively. The hydrodynamic module takes into account nonlinear effects of Froude-Krylov and restoring forces. This Fluid Structure Interaction (FSI) model is also coupled with slamming loads to predict wave loads due to whipping effects. Vibration modes and natural frequencies of the ship hull girder are calculated by idealising the ship structure as a Timoshenko beam. The results from springing and whipping analyses are compared with the results from linear and nonlinear time domain calculations for the rigid body. The results from the computational analyses in regular waves have been correlated with those from model tests undertaken by MOERI. Further the global effects of springing and whipping acting on large container ships are summarised and discussed.

Abstract:
The authors have developed a wind loads simulator (WiLS) that enables us to carry out free-running model tests for investigating wind effects on ship performance. WiLS provides a free-running model ship with simulated wind loads taking account of supposed true wind speed and direction, and instantaneous model ship speed, drift angle, and heading angle. It does not generate environmental wind but exerts forces and moment on a model ship using three pairs of duct fans. A control PC calculates time varying longitudinal and lateral wind forces and yaw moment using wind loads coefficients estimated beforehand and ship motion data, and distribute them to the three pairs of duct fans. Feedback control ensures the intended wind loads using data from load cells on which the duct fans are mounted and those from accelerometers for correcting inertia forces of the duct fans. This paper reports the concept, configuration, and control procedure of WiLS, and presents tank test data, which confirms effectiveness and usefulness of WiLS as a device in free-running model tests to evaluate ship performance at actual seas.

Full text
Abstract:
American Exchanger Services, Inc (AM-EX) performed a 2012 repair of a vertical head-up High Pressure (HP) Feedwater Heater breech lock channel during a shop based re-tube for the American Electric Power (AEP) Wilkes Power Plant, Unit 1. The 48 year old channel is a carbon steel cup-forging that had 1-1/2″ deep circumferential cracks extending radially into the tight knuckle radius at the channel barrel to tubesheet junction. A small area was also found on the backside of the tubesheet which had corroded to a depth of 7/16″. Several methods to repair these types of failures may be employed, such as grinding out the crack and weld repair, grinding or machining out the crack, leaving as is and performing regular inspections and monitoring crack propagation, or leave as is and perform a fitness for service analysis (API 579-1/ASME FFS-1). A repair was chosen that reduced the stresses in the highly stressed corner radius and was validated using modern calculations. The channel barrel was in the re-tube process so immediate access to a vertical lathe was available and this, in part, lead to the crack removal approach. The design alteration was to machine a pocket to completely remove the crack, verify tubesheet stresses are within allowable stress limits by Finite Element Analysis (FEA), and prescribe future Nondestructive Examination (NDE) to monitor potential future cracking. The size of the machined “pocket” was determined by the actual crack length “as measured” and the repair was verified using FEA. The machined pocket was Dye Penetrant Tested (PT) in September of 2013 (after approximately one year of returning to service), and no defects were noted. This is not a new repair method; in fact it was researched by Electric Power Research Institute (EPRI) in 1988 symposium [1], and based on an EPRI 1985 [2] similar repair. In the 1985 repair similar methods of FEA were employed, however using less sophisticated forms of the calculation. Modern computing allows for 3D analysis with more complex geometries, and more conservative meshing. This analysis demonstrates that the earlier papers were correct in their understanding of the problem and the proposed solutions. The Wilkes HP feedwater heater was repaired in a similar manner with a machined radius that sufficiently reduced stresses to safe levels allowing an alteration of the vessel to be in compliance with National Board Inspection Code (NBIC) [3] and American Society of Engineers Boiler and Pressure Vessel Code (ASME B&PV CODE) [4].
