DNVGL-CG-0170 Offshore Classification Projects CLASS GUIDELINE DNVGL-CG-0170 Edition July 2015 Offshore classification projects - testing and commissioning The electronic pdf version of this document found through http://www.dnvgl.com is the officially binding version. The documents are available free of charge in PDF format. DNV GL AS FOREWORD DNV GL class guidelines contain methods, technical requirements, principles and acceptance criteria related to classed objects as referred to from the rules. © DNV GL AS July 2015 Any comments may be sent by e-mail to [email protected] This service document has been prepared based on available knowledge, technology and/or information at the time of issuance of this document.

CHANGES – CURRENT General This document supersedes DNV-RP-A205, October 2013. Text affected by the main changes in this edition is highlighted in red colour. However, if the changes involve a whole chapter, section or sub-section, normally only the title will be in red colour. On 12 September 2013, DNV and GL merged to form DNV GL Group. On 25 November 2013 Det Norske Veritas AS became the 100% shareholder of Germanischer Lloyd SE, the parent company of the GL Group, and on 27 November 2013 Det Norske Veritas AS, company registration number 945 748 931, changed its name to DNV GL AS. For further information, see www.dnvgl.com. Any reference in this document to “Det Norske Veritas AS”, “Det Norske Veritas”, “DNV”, “GL”, “Germanischer Lloyd SE”, “GL Group” or any other legal entity name or trading name presently owned by the DNV GL Group shall therefore also be considered a reference to “DNV GL AS”. Changes – current Main changes July 2015 • General The revision of this document is part of the DNV GL merger, updating the previous DNV recommended practice into a DNV GL format including updated nomenclature and document reference numbering, e.g.: — DNV replaced by DNV GL. — DNV-RP-A205 to DNVGL-CG-0170 etc. A complete listing with updated reference numbers can be found on DNV GL's homepage on internet. To complete your understanding, observe that the entire DNV GL update process will be implemented sequentially. Hence, for some of the references, still the legacy DNV documents apply and are explicitly indicated as such, e.g.: Rules for Ships has become DNV Rules for Ships. Editorial corrections In addition to the above stated main changes, editorial corrections may have been made.

(May 2005) Alisa Michele Steere, B.A., Texas A&M University Chair of Advisory Committee: Dr. C. Wayne Smith A mixture of shipbuilding, architecture, and art went into producing the wooden decorative work aboard ships of all nations from around the late 1500s until the advent of steam and the steel ship in the late 19th century. The leading humanists and artists in each country were called upon to draw up the iconographic plan for a ship’s ornamentation and to ensure that the work was done according to the ruler’s instructions. By looking through previous research, admiralty records, archaeological examples, and contemporary ship models, the progression of this maritime art form can be followed.

  • H.M.S Victory 1805
    H.M.S VICTORY 1805 Exact scale model of the 100-Gun British Ship of the Line. This, the fifth ship of the Royal Navy to bear the name Victory, had three major battle honours. The first being the Battle of Ushant 1781, the second, the Battle of St. Vincent 1797 and the third, for which she is most famed, the Battle of Trafalgar 1805. By the end of the Battle of Trafalgar, there was not a mast, spar, shroud or sail on board Victory that had not been severely damaged, lost or destroyed in the conflict.

Slice the dowel (running with the grain), from a round at the start point of the taper to a square at the end of the taper. 2. Repeat this process so that the dowel runs from round at the start of the taper to an eight sided polygon at the end of the taper. 3. Repeat step two as desired so that the dowel runs from a round at the start of the taper to a 16 or 32 sided polygon at the end, of a diameter marginally more than that required.

    ANCHORS AND ANCHORING WHY DO WE ANCHOR ? • Protection of boat from storm • Provide rest for the crew • Dock space not available in a harbour • If engine get failure then to maintain sustainability of boat in water an anchor get used. Things to look for when selecting an anchor Water depth Bottom type (clay, sand, mud, rock, boulders, weeds) – Clay, sand and mud provide the best anchoring substrates – Rock shelves, boulders and weeds are the worst substrates Protection from predicted winds, protection from prevailing winds and currents or tides Size of anchorage, for room to swing ANCHOR PRINCIPLES • Two general categories of anchors: 1.Heavy weights • Used for stationary objects like navigation bouys 2. Anchors that dig into the bottom • Used on vessels and combine weight and ability to dig into the substrate PARTS OF AN ANCHOR TYPES OF ANCHOR 1. A/P or Fisherman’s anchor: Non-burying type, with one arm penetrating the seabed and the other standing upright It has a good reputation for use in rock, kelp, and grass, but is unlikely to be any more effective than a good modern design and its holding power to weight ratio is among the worst of all anchor types The primary weakness of the design is its ability to foul the cable over changing tides Fig. - Fisherman's Anchor 2. Danforth Anchor • The stock is hinged so the flukes can orient toward the bottom • The design is a burying variety, and once well set can develop an amazing amount of resistance. • Its light weight and compact flat design make it easy to retrieve and relatively easy to store Fig.

    BASIL LUBBO THE BLACKWALL FRIGATES Digitized by tine Internet Archive in 2008 with funding from IVIicrosoft Corporation http://www.archive.org/details/blackwallfrigatesOOIubb THE BLACKWALL FRIGATES BY BASIL LUBBOCK Author of "The Ch\na Clippers"; "The Colonial Clippers, "Round the Horn before the Mast"; "Jack Derringer, " a Tale of Deep Water" ; and Deep Sea Warriors" WITH ILLUSTRATIONS AND PLANS GLASGOW JAMES BROWN S- SON (Glasgow) Ltd., Publishers 52 TO 58 Darnley Street 1922 v/r Dedication Dedicated to the Blackwall Midshipmite. PREFACE The Blackwall frigates form a connecting link between the lordly East Indiaman of the Honourable John Company and the magnificent P. & O. and Orient liners of the present day. They were first-class ships—well-run, happy ships, and the sailor who started his sea life as a midshipman aboard a Blackwaller looked back ever afterwards to his cadet days as the happiest period of his career. If discipline was strict, it was also just. The train- ing was superb, as witness the number of Blackwall midshipmen who reached the head of their profession and distinguished themselves later in other walks of life. Indeed, as a nursery for British seamen, we shall never see the like of these gallant little frigates. The East still calls, yet its glamour was twice as alluring, its vista twice as romantic, in the days of sail; and happy indeed was the boy who first saw the shores of India from the deck of one of Green's or Smith's passenger ships. Fifty years ago, the lithographs of the celebrated Blackwall liners to India and Australia could be bought at any seaport for a few shillings.
