"BP FIREMA.STER" New Firefloat for Swansea Docks The firefloat "BP Firemaster" recently completed, by Messrs. R. S. Hayes (Pembroke Dock) Ltd., at the Dockyard, Pembroke Lock, South Wales, for the BP Tanker Company Ltd., is something quite new in fire-fighting craft. Designed by the Engineering Department of the BP Tanker Company Ltd., based on their experience of the use of sea-going tugs for fire-fighting purposes, the "BP Firemaster" has the combined advantages of mobility, fire-fighting potential, and ability to maintain her position alongside a burning vessel without the necessity of mooring. Propulsion of the firefloat is by two Harbormaster outboard propulsion units situated at the forward and after ends, and each operated by Dorman KUD 6-cylinder diesel engines of 140 BHP and fitted with Bryce Berger "Handraulic" starting. Both the above units can be started and operated from the wheelhouse, and as each propeller can be rotated through 360 degrees, movement in any direction can be obtained, and the firefloat held in any required position against the thrust of the monitor jets. The "BP Firemaster" comprises two pontoons, each 60ft. long, 14ft. wide and 7ft. 6ins. deep, which are joined at deck level and are also connected below water level by elliptical tubes, forming a "catamaran", the overall breadth being 36ft. Mounted on the catamaran is an open pyramid formed by four tubular steel supports at the apex of which is mounted the Control Cabin, from which the Fire­ master directs firefighting operations. Immediately below this cabin are two platforms 23ft. and 30ft. respectively, above the water-line, each giving access to monitors mounted at the forward and after ends, and port and starboard sides of the platforms. Above the Control Cabin there is one central monitor some 40ft. above the water-line, capable of operating in any direction. An unusual feature of the firefloat is the fitting of large pneumatic wheels at each extremity .of the pontoons, in order to facilitate lateral movement along the side of a burning vessel. The firefighting arrangement has been designed in conjunction with Messrs. Merrywoather and Sons Ltd. The pumping requirements are met by two Merryweather 2-stage turbine pumps, each driven by a 30 HP 6 QA Dorman diesel engine developing 215 BHP. The nine monitors are fed through a central rising main, the output being 3,100 gallons of water per minute at 100 p.s.i. and 12,500 gallons of foam. Each pontoon houses a spacious pumproom, at each end of which is a foam tank with buoyancy spaces beyond. From each main pump there is an 8" deck suction fitting which enables the pumps to be used for salvage purposes also, armoured suction hoses and foot-valves being supplied. In addition to the main pumping units each pumproom contains an 11.5 KW generator direct driven by a Lister-Blackstone FRBMA diesel engine developing 24 BHP, a belt-driven 3KW generator off the same units supplying power for charging 24/32 volt batteries. Also fitted in each pumproom is a motor-driven GiIkes, Gordon bilge pump and a motor-driven Hanworthy foam pump. A Marconi loud-hailer talk-back system is installed between the Control Cabin, each monitor station, wheelhouse and pumprooms. Instructions to pumprooms from the Control Cabin are also by means of an electrically operated telegraph. On the main deck between the pumproom skylights is the accommodation for the watch-keepers, consisting of a well fitted-out cabin with settees, tables and lockers. On the port side of this cabin there is a small galley, and to the starboard side, toilet accommodation. The cross alleyway at the after end gives access to port and starboard pumprooms. GENERAL DESCRIPTION OF 'BP FIREMASTER1 Each year 3,000,000 tons of crude oil is imported by The British Petroleum Company at Queen's Dock, Swansea, for refining by BP Refinery (Llandarcy) Ltd. A whole range of products therefore, varying fromrotor spirit to fuel oils, is exported subsequently. Today a novel type of fire-fighting float will go into service to help deal with outbreaks of fire on tankers while in the port. This unusual craft - named the 'BP Firemaster' - has been designed by the Engineering Department of BP Tanker Company on the basis of experience gained in using sea-going tugs for fire-fighting duties. Specially equipped sea-going tugs have their place in some conditions, but are not suited economically to in-dock working; and while they are some safeguard, due to their dual purpose they have disadvantages over a specially designed craft. A particular disadvantage of the sea-going tug is that in some conditions it cannot maintain a steady position relative to the scene of the fire, due to the reaction from the force of the water jets which tends to push the tug away. The exception is where the tug is fighting the fire head-on when it can use its engines to counter the force of the jets, but even in this case a strong cross wind can make it difficult for a tug to keep its position. Another disadvantage of the orthodox fire- fighting tug is its inability to use the maximum number of mech­ anical jets in any one direction. The Swansea firefloat has been designed with a single purpose and it is possible therefore to overcome the shortcomings of the orthodox tug. Its engine arrangement will enable it to move it any direction, or conversely to maintain its position against the force of the water jets and wind forces, regardless of the direction in which they are used. The water jets are so arranged that seven out of the nine can be used in any direction simultaneously. /••• - 2 - The 'BP Firemaster1 has been constructed for the BP Tanker Company by R. S. Hayes (Pembroke Dock) Ltd., at the Dockyard, Pembroke Dock. Its main features are two 33-ton pontoons, each 60 feet long and 14 feet wide, and spaced eight feet apart. These pontoons are joined together at deck level, and also at their base by elliptical tubes to form a 'catamaran'. Surmounting the catamaran hull are four tubular supports which form a tower on which two platforms and a control cabin are mounted. The fire-fighting layout has been designed in collaboration with Merryweather and Sons. There are a total of nine 4 inch gear operated fire-fighting nozzles, or 'monitors' as they are generally known. Four of these monitors are mounted on the lower platform which is 23 feet above deck level, four are fitted to the middle platform at about 30 feet above deck level, and one on the top of the Chief Fire Master's control cabin which is at the top of the tower. The arrangement is such that seven out of the nine monitors can be used in any one direction simultaneously. The tower has a total height of about 40 feet above water level, so that water or foam can be directed on to the decks of any tanker, whether in light or loaded condition. The fire-fighting and salvage pumping capacity of the firefloat is 3,100 gallons of water per minute at 100 lb. per square inch, and the foam capacity is 12,500 gallons per minute. Water or foam can be discharged from any one or a number of the monitors independently, giving the Fire Master full mobility of water or foam requirements. Among the special facilities in the Chief Fire Master's control cabin is a loud-hailer talk-back system to enable in­ structions to be given to the navigation house, engine rooms and the firemen manning the monitors. A portable walkie-talkie r wireless set can also be used. /••• An interesting feature is the fitting of heavy lorry wheels at the forward and after ends of each pontoon to assist the movement of the firefloat along the side of a ship. When the 'BP Firemaster1 goes into service at Swansea today, it will be moored alongside a small jetty in Queen's Dock by quick release mooring ropes. The firefloat will be maintained permanently ready for service and will have a regular crew of two, one man for navigation purposes and the other for starting up the dies el driven fire pumps and propulsion units. All the engines are push-button started so that water or foam can be available at any monitor within a few seconds. The fire-fighting personnel will come from the Swansea Fire Service who can arrive on the jetty to man the firefloat within three or four minutes of call. The 'BP Firemaster' will be ready to leave its berth to deal with any outbreak immediately the Fire Service personnel are aboard. During fire-fighting operations the float will be under full control of the Chief Fire Master. Thus, today, the port of Swansea has for its protection what is probably the most modern and useful fire- fighting craft in the world. The 'BP Firemaster' is believed to be unique in its design and has already aroused great interest outside the United Kingdom. .

    NAfWEntBusCtteePortsQ’s NATIONAL ASSEMBLY FOR WALES ENTERPRISE AND BUSINESS COMMITTEE PORTS AND AIRPORTS INQUIRY Additional Questions on Ports Question 1A - Opportunities for Welsh ports in supporting the renewable energy sector Not really one for me in detail. In general terms there are opportunities to use any steel / coal port facilities. The Port Talbot Tidal Harbour (the outer dock) is used extensively for deep water ore and steel movements. There is a plan for a jetty development. (ABP will be able to give the present construction position) This is a high capacity facility which would be ideal for importing bulk bio-fuel material. Swansea docks have been used to import coal and I recall a plan to import coal and biomass. However I have been unable to locate the detailed papers. Margaret Llewellyn might be able to help you Question 1B – What action should the Welsh Government to support those opportunities There is a difficulty here in terms of the split responsibility of the Welsh Government (WG) and the UK Government, Department for Transport (DfT).(Please see my original brief to the Committee) The Welsh Government commissioned the Wales Freight Strategy (2008) which set out a series of objectives and steps to delivery. I referred to this in my evidence. The Welsh Government is responsible for managing the Freight Facilities Grant and also I believe the Ports Facilities Grant (a DfT funded grant). However the WG is not responsible for investment in ports and receives no black grant element for so doing. As I explained in my evidence the DfT (acting in its capacity as the ‘English Government’) does not see any rationale for funding ports in England.

    NAfW inquiry into international connectivity through Welsh ports and airports February 2012 INTRODUCTION 1. The Welsh Local Government Association (WLGA) represents the 22 local authorities in Wales, and the three national park authorities, the three fire and rescue authorities, and four police authorities are associate members. 2. It seeks to provide representation to local authorities within an emerging policy framework that satisfies the key priorities of our members and delivers a broad range of services that add value to Welsh Local Government and the communities they serve. 3. The WLGA welcomes this opportunity to feed comments into the NAfW‟s inquiry into international connectivity through Welsh ports and airports. Tables 1 and 2 below show that local authorities have a major interest in this issue with ten authorities having an airport/aircraft facility in their area and eight having a port – six have both. Overall, twelve authorities have an airport and/or a port – all of varying degrees of scale and activity. (In addition there are a number of former ports that have ceased to operate on a large scale but now house other activities including fishing and tourism related activity).

  • 2. Urban Geology of Swansea and Port Talbot
    Waters et al . Urban geology of Swansea and Port Talbot 2. Urban geology of Swansea and Port Talbot Waters, C N, Price, S J, Davies, J, Tye, A M, Brown, S E & Schofield, D I The conurbation of Swansea–Neath–Port Talbot is one of the main centres of industrial development in South Wales. A long history of mineral extraction and processing, which stoked the initial growth of the towns, declined during the 20 th Century. Many of these former industries have left a legacy of groundwater, water- course and land contamination. A project funded by the Environment & Hazards Directorate (British Geological Survey) between 2000-2005 used available geological data to determine potential areas of contaminated land and understand the influence of the geology to pollutant pathways (Waters et al ., In press a). The study covered 100 km 2 of the Swansea- Neath-Port Talbot area (Fig. 2.1) and was aimed at providing data relevant to contaminated land issues, to augment the study by Arup (1997) on earth science information relevant to planning and development for the Swansea-Llanelli district, and look at new methodologies of presenting the data. Contaminated land is defined as areas where a Source-Pathway-Receptor linkage can be established (DoE, 1995). In order to determine Source areas it is necessary to appreciate the industrial development of the region by collecting information on current and former land use and the extent and nature of artificial deposits. The degree that contamination of Source areas is a problem can be established from analysis of soil geochemistry. The Pathway component represents the migration of contaminants through the air, surface water or groundwater.

The most common, B. neritina, was known from a few sites in southern Britain and northern France during the 20th century, following its discovery at Plymouth by 1911. During the 1950-60s it was abundant in a dock heated by power station effluent at Swansea, south Wales, where it flourished until the late 1960s, while water temperatures were 7-10°C above ambient. It disappeared after power generation ceased, when summer temperatures probably became insufficient to support breeding. Details of disappearances have not been recorded but B.

  • Marine Vhf Radio Channels
    GUIDELINES ON USE OF MARINE-BAND VHF RADIO BY INLAND PLEASURE CRAFT ON UK FREIGHT WATERWAYS with advice on navigation lights, sound signals and navigational safety A guidance note prepared by IWA’s Inland Waterway Freight Group 1 GUIDELINES ON USE OF MARINE BAND VHF RADIO BY INLAND PLEASURE CRAFT ON UK FREIGHT WATERWAYS with advice on navigation lights, sound signals and navigational safety A guidance note prepared by the Inland Waterway Freight Group of the IWA SUMMARY Marine-band VHF radio provides a means for vessel crew to communicate with other vessels and shore station (e.g. ports, locks, bridges and marinas) on operational, navigation and safety matters. As well as providing an effective means of calling for help in an emergency, use of marine- band VHF radio can inform you of the presence of large vessels and their intentions, as well as providing a means to call for locks to be prepared or moveable bridges to be swung or raised in advance of your arrival. Simply listening to the appropriate radio channel will provide a picture of vessel traffic, which may enable you to avoid meeting a large vessel in an awkward location, for example. Availability of radio-communication and establishment of vessel traffic services (VTS) in some areas has contributed to the penetration inland of larger vessels than hitherto, presenting an increased hazard to small pleasure craft. Marine-band VHF radio has become widely used on larger waterways, replacing flag signals and to some extent sound signals, so that if your vessels is not so equipped, you may be exposing yourself to unnecessary risks.
