Looking back, it was a time of change and a time of progress in many areas, and the field of gas ship design was no exception. Designers and engineers from across the world independently began to address the challenge of transporting liquefied gases in bulk at close to atmospheric pressure. I had the good fortune to be a member of the small design team, in the appropriately named Prospect Work Department (PWD), who were preparing designs, estimates and bids to win the first United Kingdom order for a fully refrigerated Liquefied Petroleum Gas (LPG) carrier. Perfectly named for a gas carrier, the ship was delivered as Clerk-Maxwell. Great days, great memories. I have always felt that this fascinating and challenging period of gas ship design should be recorded. The chapters of this book are loosely arranged around each ship building yard, as each made a significant contribution to making the safe sea transport of liquefied gases in bulk the success it is today. This progress was generally made independently by the yards and as such, each has a story in its own right. Many yards had unique and distinctive characteristics which were built into the designs and were often repeated and improved on later ships, as experience was gained and capacities increased. The chapters begin with each yard’s first FRLPGC and continue to the present day, or to the last built before a yard closed. To identify the various historical milestones and to settle any arguments and claims, I would refer you to Appendix 1 and the chronological listing. The scale of each of the drawings has been chosen to fit the pages and as such each drawing is small and each scale is large. The drawings are intended to give a general indication of the overall design of the ships and few details have been included. Rest assured that all of these ships have lifeboats, guard rails, winches, derricks, windows etc, but these items are not shown for the sake of clarity. Throughout the text, the original name of each gas ship has been used to identify the design. The Appendices show listings of the original and current names as well as name changes for all of the ships featured. My task has not been easy with so many of the shipyards experienced in building gas ships now long gone. This includes such famous names as Boelwerf SA, Temse, Belgium, Chantiers Navals de la Ciotat, La Ciotat, France, Constructions Navales & Industrielles de la Méditerranée (CNIM), La Seyne, France, Euskalduña, Bilbao, Spain, R & W Hawthorn Leslie & Company, Hebburn-upon-Tyne, United Kingdom and Kockums Mekaniska Verkstads AB, Malmö, Sweden. Key pioneering manufacturers of equipment and components have also vanished. In addition, in my early stages of research I discovered, that the notorious fire in Le Havre in August 1997 did not just destroy files from French state owned bank Credit Lyonnais, which was being investigated in a financial scandal. Also stored in the same building, and also destroyed, were many drawings and documents covering the early days of the LPG vessels belonging to Gazocéan. The high cost of storage, the takeover of smaller companies by disinterested major companies and the closure of key shipyards have meant that many useful documents have been shredded, destroyed or discarded as being of no value. There was also great secrecy in the early days of gas ship design and construction. I heard of one shipyard, where workers’ personal notebooks used during the construction of the gas ships were destroyed when the ship was delivered.

In addition, the materials in direct contact with the liquid cargo must be matched with the properties and characteristics of the cargo. The key to the designs is the atmospheric boiling temperature of the liquid cargo, i.e. ambient for fully pressurised LPG, -33°C for anhydrous ammonia, -48°C for propane, -104°C for ethylene and-163°C for LNG. LPG carriers can be grouped into three categories; fully pressurised, pressurised and refrigerated and fully refrigerated. The first ships designed to carry LPG were fully pressurised and today there are many trading routes where butane and propane are still transported under pressure at ambient temperature. Almost half of the total number of LPG carriers in service are small fully pressurised ships, with most operating coastal or island services in Japanese, Korean, Chinese and Caribbean waters. The most versatile LPG carriers are the small to medium sized pressurised and refrigerated vessels, with capacities up to 30,000 m3, capable of loading and discharging a wide range of LPG and chemical gases. Modern gas carriers of this type are generally designed for a minimum temperature of -48°C, a maximum pressure of 5 to 8 kg/cm2 and a maximum specific gravity of 0.97 for vinyl chloride monomer (VCM). The design of fully refrigerated LPG carriers has evolved over the years from other types of LPG carriers, to make the most efficient use of the on board cubic space available. The minimum design cargo temperature is generally -48°C for propane, with the maximum design pressure 0.25 kg/cm2 greater than atmospheric pressure. Fully refrigerated LPG carriers have been built with capacities up to 100,988 m3. Apart from the cargo temperature, the FRLPG carrier has more in common with the LNG carrier than the smaller pressurised LPG carriers. Much of the extensive research and development of the late nineteen fifties and early nineteen sixties on LNG carriers also resulted in the first designs for fully refrigerated LPG carriers.1 There is a considerable overlap of the techniques which have gone into both the LNG carrier and the FRLPG carrier, each with many similar design features. Throughout the gas ship building industry the learning curve has been gradual with yards progressing to larger vessels after cutting their teeth on smaller ships. Most yards with fully refrigerated LPG ship building experience moved on into the LNG market. A notable few exceptions were; Harland and Wolff, Chantiers de France Dunkerque, Boelwerf and Daewoo, who took the reverse approach and started with LNG carrier construction. When comparing the construction of the first purpose built fully refrigerated LPG carrier, Bridgestone Maru, delivered from MHI in 1961, with a typical modern FRLPG carrier, the differences in general appear to be slight rather than radical. This was not so in the decade following the delivery of Bridgestone Maru, particularly in Europe, where ships were delivered with a selection of tank shapes and insulation arrangements. A popular arrangement on many earlier ships included above deck trunks, allowing an increase in cargo capacity without any increase in hull dimensions. With experience, the shipbuilders found that the tanks with trunks were not so easy or cheap to construct, particularly with the increased number of the tanks’ radius edges and part spherical shaped corners. Naval architects quickly realised the advantages of constructing FRLPG carriers with a flush deck, with longitudinally framed sloping upper and lower wing ballast tanks at the sides and a transversely framed side hull forming the secondary barrier. This arrangement, which WSIL - 270 - Fully Refrigerated LPG Carriers.indd ixWSIL - 270 - Fully Refrigerated LPG Carriers.indd ix11/10/2009 10:06:32 AM11/10/2009 10:06:32 AM x first appeared on 25,540 m3 Antilla Cape, delivered from A. G. Weser in 1968, has now become almost the standard configuration for the modern FRLPG carrier. In fact, every fully refrigerated LPG carrier delivered since 39,113 m3 Kelvin, from IHI in 1990, has had this arrangement for cargo tanks and water ballast tanks. The IHI ship had a slight variation on the standard arrangement by having the inner bottom extending to the side hull to form the lower water ballast tanks. In 1976, the Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk was first published by the then Inter-Governmental Maritime Consultative Organization (IMCO). For the first time, the Code set out international standards for the safe carriage of liquefied gases in bulk. From the time of the first meeting, in September 1971, of an Ad Hoc Working Group within IMCO 2, until the Code was published in 1976, shipbuilders were well aware that the pending Code would require changes to the design of FRLPG carriers. As it turned out, wholesale changes were not required to existing practices, rather a fine tuning of layouts and tank locations within the ship, with extra safety, fire-fighting and monitoring equipment added. The main areas requiring changes were; damaged stability requirements, cargo tank and ballast tank locations, segregation of the cargo area, openings in accommodation spaces and fire protection systems. The new Code had more radical effects on the design of smaller LPG carriers than on larger LPG carriers. In the intervening years the Code has been reviewed, revised and amended. The 1993 edition published by the International Maritime Organization (IMO), became the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code). A number of the earlier built LNG carriers were designed to carry both LNG and LPG, as no long term LNG trading had yet been fixed at the time of ordering, and the spot LPG market offered opportunities for employment of the ships. Some of the smaller LNG/ LPG carriers were also able to load ethylene. Few traded with LPG cargoes and detailed descriptions of these ships have not been included in this book, as the ships are primarily LNG carriers. One technical point, which may have contributed to the remarkable life span of these vessels is that the carriers were designed for a propane specific gravity of 0.58. This represents a considerable margin of safety when loading LNG with a specific gravity of 0.44. The following is a brief summary of the combined LNG/LPG and LNG/LPG/ethylene carriers built: Esso Brega • now LNG Palmaria – 41,000 m3 with Esso prismatic tanks built at Italcantieri, Genoa, Italy in 1969 and modified to carry LPG at Moss Rosenburg, Stavanger, in 1976.

Ltd., New York.1 During this meeting the basic idea of refrigeration for the transportation of LPG by sea was discussed with the potential seen, if the transport costs could be reduced, to open up large new markets for the use of LPG. For this new business venture, Trelleborgs Ångfartygs AB enlisted the services of consultants Marine Service GmbH of Hamburg for the design work on a purpose built 25,000 m3 LPG carrier. The contract for the newbuilding was placed with Swedish shipbuilders Kockums Mekaniska Verkstads of Malmö. Through A L Burbank & Co. Ltd., a long-term charter was obtained from Phillips Petroleum Company of Bartlesville, Oklahoma, USA., to export LPG from the Gulf of Mexico on transatlantic trading routes.

Cargoes carried were anhydrous ammonia, propane, butane, butadiene and ethylene oxide, at a minimum temperature of -51°C and a maximum pressure of 0.3 kg/cm2. Many new techniques were required, relating to the special steels, welding and insulation materials, which had not previously been encountered in conventional shipbuilding. A laboratory was set up in the shipyard for testing, problem solving and the evolution of instruments and cargo handling equipment. The profile of the ship was distinctive with a forecastle deck, trunk deck, large amidships deckhouses for the cargo control room and gas plant with the cargo vents grouped above it, four large cylindrical deck tanks and an aft superstructure. The hull was of all welded construction, except for double riveted crack arresting seams located at the bottom shell, at the lower turn of the bilge, at the deck sheer strake and at the trunk deck. The prismatic cargo tanks were each located in the five hold spaces below the main deck. A double bottom and a double side hull were used for water ballast. Transverse cofferdams were fitted between each hold space. In addition, two 106 m3 vertical cylindrical/conical shaped pressure vessel tanks were fitted in the forward part of No. 1 hold space. Four 300 m3 horizontal cylindrical pressure vessel tanks were fitted at the sides of the main deck. WSIL - 270 - Fully Refrigerated LPG Carriers.indd 95WSIL - 270 - Fully Refrigerated LPG Carriers.indd 9511/10/2009 10:06:59 AM11/10/2009 10:06:59 AM 96 Domnarvet Steel Works, in co-operation with Kockums, produced the special steel for the main cargo tanks and inner hull, which formed the secondary barrier. This was a fully-killed fine-grained manganese low carbon steel with minimum impact properties of 2.8 kpm/cm2 at -57°C. The tanks’ were supported by steel foundations and brackets on the bottom of the tanks, cushioned with tropical azobé hardwood and Swedish pine. Azobé was also used for the rolling and pitching keys as well as the anti-lift chocks. The hold spaces were insulated with two 50 mm thick layers of polyurethane foam which were glued to the inner hull, the cofferdams and the underside of the main and trunk decks. The arrangement with the insulation on the inner hull rather than on the cargo tank made for some interesting design features. It was possible to have direct access to inspect the outside plating of the cargo tanks where walkways were installed. In normal service the hold spaces would be filled with inert gas produced from an on board system with two nitrogen generating plants. For the carriage of chemicals which could not be handled by the reliquefaction plant, cooled nitrogen gas could be circulated in the spaces around the cargo tanks. This alternative cooling system was designed to maintain the cargo at -7°C. Fans were used to circulate the nitrogen gas after passing through a cooling battery connected to one of the reliquefaction plants. The vessel was fitted with three reliquefaction plants, each consisting of an oil free two-stage Sulzer compressor, a Stal refrigeration unit using Freon 22 as a coolant, a gas condenser, a receiver and related valves, gauges and controls. Named after the vice-chairman of Phillips Petroleum Company, the vessel was christened by Mrs. Endacott, his wife, on 27 November 1963. Paul Endacott was delivered to the owners on 28 May 1964 and was the first purpose built fully refrigerated LPG carrier constructed in Europe. On 29 May 1964 Paul Endacott left Malmö bound for Mena al Ahmadi, Kuwait, to load the first of four consecutive LPG cargoes for Japan, under a sub-charter to the Bridgestone Liquefied Petroleum Company Ltd., of Tokyo.5 Delays in the preparations of the terminals for the planned regular transatlantic LPG service, opened up the opportunity for this temporary trade to the Far East. On 1 April 1965, onboard Paul Endacott, the first shipment of propane, under the Phillips Petroleum contract, reached the Phillips United Kingdom’s terminal at Felixstowe, for delivery to the Eastern Gas Board.6 The building of this new import terminal was made feasible late in 1962, when the Felixstowe Dock and Railway Company agreed to construct a deep-water jetty. The contract was finally agreed when an offer was made, by Phillips, to deliver gas from the Gulf of Mexico, at a competitive price. That decision must have given great satisfaction to the forward thinking entrepreneurs Frans Malmros and Peter Burbank. The new 33 m high and 52 m diameter refrigerated storage tank at Felixstowe provided facilities for road and ship loading as well as a non insulated pipeline connection to Norwich. The Eastern Gas Board Cremore Gas Works in Norwich was equipped with five high pressure reforming plants and the piped liquefied propane was used to enrich the local town gas. By an odd coincidence, the Norwich end of the pipeline was located about ten kilometres from where these words have been typed. Paul Endacott as Petrogas I was reported broken up in 1986.
