achieve the necessary levels of corrosion protection. Te 100amp forward systems will consist of an
arrangement of reference electrodes and anodes (mounted port and starboard) wired to a thyristor control panel. Te reference electrodes measure the electrical potential at the hull/seawater interface and send a signal to the control panel which automatically raises or lowers the output to the anodes. The ships will have more powerful 200amp aft
systems to counteract the effects of turbulence and the proximity of dissimilar metals in propulsion systems at the stern of the vessel. In this way, the vessels receive the optimum level of protection at all times. Cathelco will also be supplying seawater pipework
anti-fouling systems for the vessels. These are designed to prevent blockages in seawater cooling lines caused by the growth of barnacles and mussels. Te cross-over sea chests serving the main engine,
auxiliary engine and fire fighting pumps will be fitted with pairs of copper and aluminium anodes wired to a control panel. A similar system will also protect sea chests serving the heating, ventilating and air conditioning equipment. In operation, the copper anode produces ions
which are carried throughout the system by the flow of seawater and create conditions where barnacle and mussel larvae do not settle or breed. At the same time, the aluminium anode produces ions which create a cupro-aluminium film on the internal surfaces of pipes to suppress corrosion. Te latest orders follow the successful installation
of similar equipment on the BPC Dixmude, the third Mistral class vessel, which was delivered to the French Navy by DCNS and STX France in January 2012.
Submarine rescue QinetiQ sub rescue system
support for Fincantieri QinetiQ in the UK has provided Italian ship builder Fincantieri with specialist design and advisory services in support of the development of an on-board escape system for the Italian Navy’s newest submarines. QinetiQ were engaged at the beginning of the new
submarine construction project conducting a feasibil- ity study, providing advice, system and component evaluation, design and sea trials support. Fincantieri
Achieving new depths in submarine design
When it comes to the nation’s security, only the best will do. That’s why you’ll want outstanding engineering partners with the highest levels of experience, integrity and creative thinking.
BMT has all these. Which is why we’ve worked with Government departments and defence agencies, major defence and industrial contractors and shipbuilders in the UK and overseas since 1985. We don’t just design submarines, warships and auxiliaries, we also provide you with a watertight business case, ongoing support and valuable peace of mind.
So when you decide to work with BMT you’ll be putting together a highly successful partnership.
