HIGHLY TOPICAL IMarEST LECTURE LOOKS AT MAINTAINING SAFETY AND ENVIRONMENTAL IMPACT IN AN ECONOMIC DOWNTURN
|
|
A significant change in the shipping industry from the viewpoint of the safety and impact on the marine environment has taken place over the last forty years. However, the current economic climate could have a major impact on this vital area in the opinion of Martin Shaw, Vice President HSSE, BP Shipping. He will deliver the Institute of Marine Engineering, Science and Technology (IMarEST) Stanley Gray Lecture 'Safe Ships, Clean Seas and Climate Change' on Tuesday 7 July 2009.
"The long-running boom has turned down," says Martin Shaw. "The boom generated funds to purchase new vessels and operate to high standards. The trade-off between cost and safety has not been at the forefront of the industry's mind. As we move into the downturn, the imperative to maintain and indeed improve standards remains. How do we continue to improve safety and reduce pollution in difficult times? Overlaid on this is the climate change agenda, which is becoming more prominent and which will also impact on marine technology."
"Martin Shaw has certainly picked a compelling title bringing together three key elements affecting the shipping industry, and by overlaying these three with the effects of the economic downturn he will most certainly provide our audience with much food for thought and debate at the next Stanley Gray Lecture," says Marcus Jones, Chief Executive of IMarEST.
The lecture, being held at IMarEST HQ at 80 Coleman Street, London EC2R 5BJ is free to attend for IMarEST members and costs £15 (incl VAT) for non-members. Tea will be served from 1700hrs; the lecture will begin at 1730hrs and a post-lecture reception will begin at 1845hrs. Reservations can be made online at www.imarest.org, through direct contact with the IMarEST Events Department at +44 (0)20 7382 2655 or at events@imarest.org
About Martin Shaw
Martin Shaw MBA CEng CMarEng MIMarEST joined BP Shipping as an Engineer Cadet in 1973 and, after service up to second engineer on a wide range of tankers and offshore vessels, completed his Extra First Class Engineers certificate at Glasgow in 1985 before joining BP Shipping ashore.
He has held a wide range of posts from Fleet Safety Officer and Engineer Superintendent to Fleet Manager, Regional Director, and Business Development Manager, as well as secondment to other BP companies in the offshore and LNG businesses. He completed a Masters degree in Business Administration from Cranfield School of Management in 1989.
About Stanley Gray and the Stanley Gray Lectures
The IMarEST Stanley Gray Lectures (and the annual Stanley Gray Awards) are named in memory of Stanley Gray who was the Chief Mechanical Engineer at the Port Directorate of Basra during the 1950s & 60s. When he died in 1973 he left half his estate to be held by the Institute in trust to create the Stanley Gray Fund. He expressed the wish that the money should be awarded via a scholarship or prize to wherever the Institute saw distinction in Marine Engineering. This remit has been expanded following due process to include Marine Science and Technology. The Stanley Gray Series of prestige lectures, launched in 2002, is held to mark his generosity to, and patronage of the Institute.

TIDELAND LED LANTERNS REPLACE ROTATING BEACONS IN ALBANIAN LIGHTHOUSES
|
|
The Italian Navy, which provides technical assistance to the Albanian Lighthouse Authority, has chosen MaxLED-800 lanterns from Tideland Signal to replace traditional rotating beacons in lighthouses around the coast of Albania.
The MaxLED-800 is one of a family of stackable lanterns containing two, three or four tiers of high-performance EFF LED flashers. In the Albanian installations, they will be used in a bi-form arrangement showing a white light of 24,000+ candela, visible over 360° and a range of 16+NM. This solution offers integral standby capability, as one MaxLED-800 operating alone would still achieve a range of 14+NM in the unlikely event of one lantern failing.
Tideland LED lanterns require little maintenance, offer minimal power consumption and an operating life in excess of 50,000 hours. They use a DC power supply and are ideally suited to solar installations. Since the MaxLED 800s flash at duties often as low as 10% power consumption and operating costs are very low compared to rotators running at 100%.
 The exceptional range performance is achieved by a powerful, one-piece lens with proprietary Tideland optics, which projects light in an even and consistent 360° horizontal beam pattern. Features include full monitor and control access, user-selectable flash characters and power setting for multiple visible range performance. Constructed in rugged, corrosion-resistant marine aluminium, the MaxLED family is designed to withstand the most severe environments, from ice-bound latitudes to the tropics.
Nine lanterns, including one spare have been purchased for the first phase of the lighthouse refurbishment project. The Italian mission in Albania includes a number of specialists from the Italian Navy, who have jurisdiction in the fields of marine cartography and beacons. Albanian officers will be responsible for the installation and maintenance of the Tideland lanterns.
Approved to ISO 9001:2008, Tideland Signal Limited is a British-based member of the Tideland group of companies, which specializes in the design and manufacture of aids to marine navigation. The Tideland group is independently owned and has its headquarters in Houston, Texas.

IMAREST AN OFFICIAL SUPPORTER OF SHIPREPAIR & CONVERSION
|
|
The Institute of Marine Engineering, Science and Technology (IMarEST) is pleased to be an official supporter of the ShipRepair & Conversion exhibition and associated conference, being held at London's Olympia 28-30 April.
"We are looking forward to meeting IMarEST members and non-members alike," says Marcus Jones, Chief Operation Officer of the IMarEST. "The fact that ShipRepair & Conversion has a new focus on business and a broader visitor appeal to attract key buyers from all over the UK and the rest of Europe certainly suits us. A longer, three-day, open period will make it easier for busy buyers to attend, and allow more time for us, and other exhibitors and supporting organisations, to have substantial business conversations.
"Many of our members are actively involved with the event and we look forward to updating them on our 120th Anniversary activities and other Institute activities. We are also looking forward to making new contacts and explaining the advantages of membership including individual membership and our Marine Partners scheme which is proving of great appeal to a number of organisations."
The IMarEST stand (E42) at ShipRepair & Conversion features a 25% discount on membership subscriptions and a 40% discount on subscriptions for the two IMarEST journals that are the event's media partners - 'MER' and 'Shipping World & Shipbuilder'. A 15% discount will be available throughout the show on IMarEST books, the latest of which is 'Safe Operation of Marine Power Plants'
An analysis of ship accidents reveals that about 80% of them result from erroneous and incorrect actions of ship and shore personnel. Many accidents would never happen if the engines and automation systems had sufficient operational capacity in emergency situations, and if modern methods of team building and crew resource management were applied.
'Safe Operation of Marine Power Plants' by Professor Vladimir I Lanchukovsky, PhD, CEng, FIMarEST, the latest title in the IMarEST Marine Engineering Practice Series, explains the safe control of marine automated engines, the role of governors, distribution of engine load, prevention of overload and incomplete fuel combustion, and includes algorithms of main engine safe control when malfunctions occur. It also
draws attention to risk assessment, the identification of hazards and the importance of formal safety assessment of loss of propulsion. Finally the important safety benefits of simulator training based of full mission UMS engine room simulators are detailed.
Prof Lanchukovsky explains the definition of the safe operation of power plants: "Operation with the minimum risk of accidents or faults which can cause loss of ship propulsion. Safe operation is carried out in accordance with the rules of operation and maintenance of ships and is based on the maximum use of human resources and modern means of automation."
With its chapters on 'Problems of power plant safe operation', 'Diesel propulsion plant operation', 'Safe control of marine automated engines', 'Formal safety assessment of loss of propulsion', 'Simulator training of marine engineers', and invaluable glossary, the new book is written in accordance with the approved teaching syllabus of 'The safe operation of power plants' aimed at improving the safe operational skills of marine engineers before sending them to sea.

TIDELAND MARITIME WARNING SYSTEMS FOR OFFSHORE WIND FARMS
|
|
Tideland Signal, the international specialist in aids to marine navigation, is offering consultancy services and a comprehensive range of equipment for the safe marking of offshore wind farms to protect against collisions and accidental damage caused by shipping.
The Tideland range includes lanterns, fog signals, fog detectors and monitoring systems, all compliant with the requirements of the International Association of Lighthouse Authority's new recommendations O.139 edition 1 of December 2008 covering the marking of man-made offshore structures. IALA recommendations have the force of a 'standard' in intergovernmental terms and are designed to "avoid confusion from a proliferation of aids to navigation in high density wind farms." The document recommends that "consideration should be given to the use of synchronised lighting, different light characters and varied light ranges" and draws attention to the danger of interfering with ship borne and shore-based radar installations.
All Tideland systems can be solar-powered and may be conformed as highly sophisticated, remotely-monitored systems or simpler installation which can also be controlled from a remote, on-shore location. The company has many years' experience protecting offshore installations of every type around the globe, including the UK's largest offshore wind farm to date at Lynn and Inner Dowsing in the Greater Wash, off the Lincolnshire coast. 
Tideland supplies a wide range of compact, high-performance LED lanterns for offshore installations, including self-contained, solar-powered units such as the SolaMAX-155, which has a range of 5 NM. The integral solar panel charges an internally housed battery types, either of the lead acid type or, for extreme low temperatures, nickel metal hydride. Maintenance requirements are minimal and the unit is designed for a service life of seven years on station in the most demanding environments. Long-life LEDs and high-integrity electronics housed in a tough UV-resistant polycarbonate enclosure ensure that the lantern will not need to be opened during its service life and will even withstand being submerged in salt water.
There is a choice of three programming modes. SolaMAX-215 can be factory-programmed to the required setting or, alternatively, the user can programme it either by radio remote controller or from a laptop using Tideland's SignalView program. In addition to code setting, the SignalView program allows the user to set preferred levels for power/intensity, photo cell switching and low voltage disconnect/activation.
The fog signals supplied by Tideland for the Lynn and Dowsing wind farm were its proven AB-560 units, which give a warning audible at up to two miles. The Tideland AB-560 fog signal incorporates five drivers/emitters producing 133.2 dB at 1 metre equivalent and with a usual range of 2NM. It broadcasts a 360º sound beam, with a pre-selected code and can be operated either from mains power or a solar power system. The drivers/emitters are housed in robust GRP casings and are mounted in a galvanized steel structure designed to withstand severe storms. They operate at less than 25% of rated capacity, which results in exceptional efficiency and life expectancy.
Approved to ISO 9001:2008, Tideland Signal Limited is a British-based member of the Tideland group of companies, which specializes in the design and manufacture of aids to marine navigation. The Tideland group is independently owned and has its headquarters in Houston, Texas.
