Seals and lubrication go into historical
ship
Buried in the traditional framework of the Gotheborg III is some of the latest technology, including condition monitors from SKF.
One of the world's largest fully rigged sailing ships, the Swedish built Gotheborg III, is to sail into the port of London on the 19th May on the homeward leg of a two-year voyage The vessel is an exact replica of Gotheborg I, one of the famous East Indiamen which plied the lucrative trade routes from Europe to China in the seventeenth century, and is sponsored by a number of international organisations
These include SKF, which has provided a range of bearings, seals, lubrication and condition monitoring systems used on critical onboard equipment.
The original vessel ran aground in the entrance to its home port of Gotheborg on 12th September 1745 on the return from its third trip to China, which had lasted for over two and a half years.
Although all of the crew and much of the valuable cargo of tea, porcelain, silk and spices were saved, the Gotheborg sank and it was not until 1986 that a marine archaeological expedition began to salvage what was left of the vessel.
This project lasted six years and culminated in a programme to construct an exact and fully working replica, with the keel being laid down in 1995 and the first sea trials being carried out almost ten years later.
Although the new vessel is built to the original plans, with a length of 58.5m, beam of 11m, almost 2000m2 of sail and a displacement of 1150 tonnes, modern marine regulations dictate that the Gotheborg had to be built to ensure the safety of the vessel and its crew.
As a result, buried in the traditional framework of the ship is some of the latest technology, including five watertight steel bulkheads that reach up to the upper deck for maximum safety at sea, two main engines with adjustable propellers and a combined output of 800kW for manoeuvring in ports and narrow channels, and two main generators powered by auxiliary engines capable of producing 180kW for the onboard power supply.
In total, there are around 40 different built-in systems for propulsion, power, heating, water, sanitation, ventilation, pumping, lighting, communication and navigation.
As an official partner to the project, SKF has provided valuable assistance with technical and commercial support and the supply of essential components.
These have included bearings and units for electric motors, compressors and propeller shafts, seals in pumps and fans, lubrication systems in the engine room and, of perhaps greatest importance, condition monitoring systems for both onboard and remote assessment of critical systems.
The condition monitoring systems incorporate a network of permanently mounted sensors, in the engine room, on electric motors and other essential equipment.
These are linked via centralised Multilog CMU units that initially process data before uploading it via a satellite link to SKF's monitoring centre at its headquarters in Gotheborg.
Using the company's Aptitude Exchange software, technicians are then able fully to analyse the data and immediately advise the ships' Chief Engineer of any impending problems.
In addition, SKF's Machine Analyst software is used on board, while crew members also use Marlin Pro handheld vibration meters to carry out routine checks on shafts, bearings and other rotating equipment.
The Gotheborg will be in London from London 19th May to the 2nd June, initially sailing through Tower Bridge and being moored alongside HMS Belfast, before anchoring in the West India Docks. Request free introductory details about products from SKF UK ...
