Volvo Ocean Race
Extremes Of Imaging
By Steven Preston There is an old saying amongst yachting fraternity “saltwater and electronics don’t mix”. But the dramatic coverage of the Volvo Ocean Race underscores the robustness of modern media equipment when exposed to some of the harshest maritime conditions
Tristan Wood, Managing Director of Livewire Digital, said: “The Livewire Digital High Definition (HD) cameras have been designed for maritime applications, especially racing yachts, without possible to take the head and integrate this into a purpose built location without having to be concerned about waterproofing as the block, lens and optical window is a single hermetically

will be mounted, integrated, powered and controlled. “There is always a balance between weight, size, power, cost and function. Custom camera technology requires a significant

compromising optics or video performance. The remit is not ‘day sailing’ in favourable conditions, but to survive the toughest oceans, extremes of temperature in one of the harshest environments.” The new generation of Livewire Digital cameras are smaller, lighter and more feature rich than the 2008-2009 versions. The Roll Compensated (RC) camera models are half the weight of the first generation cameras. The PTZ cameras, as fitted to the mast spreaders are around a third of the size of those previously used. “Being a modular design it is

sealed component,” explained Wood. “The Roll Compensated cameras have a silicon fluid damped mechanism for keeping the horizon level. The applications for these cameras are for the stern or mast base where the orientation is in line with the centre line of the yacht. For such applications the mechanical approach offers a very reliable solution and does not use yacht power to maintain a level horizon.” When designing cameras for such challenging conditions, it is necessary to consider the overall system requirements – how they

investment but by carefully choosing the right components and manufacturing process it is possible to deliver a professional product to budget,” said Wood. The winner was the Sony FCBH11 camera block as the balance of weight, size and cost “remains strongly in favour of the Sony model” he said. But cabling weight, at around 500g for every 10m of cable, which as Wood points out “can quickly dwarf the mass of the camera itself” saw Livewire Digital design a new communications technology that allows a single CAT5 cable to

supply power, deliver broadcast quality 1080i HD video and provide communications with the camera head. This cut the weight of the cabling in half for the RC cameras and simplified the cabling for the PTZ models. The camera systems must withstand the harsh environment yet make no compromises on the image optics. “The Livewire Digital HD cameras have flat sapphire glass windows and incorporate HD wide-angle lenses. The use of a WA lens presents a significant engineering challenge as the mass of the HD optics outweighs that of the camera block. Therefore, the mechanical design must support the optics and take special consideration of the centre of gravity given that the camera must withstand the continuous shock of a yacht slamming,” said Wood. “Connectors are often the weak link and have been a key consideration for our MkII design. The new models see the connector housing machined into the body of the camera so there are fewer parts and enhanced reliability.” The enclosures are constructed from a combination of engineering plastics, stainless steel and black anodised aluminium components with EPM rubber seals. Machining of components was left to an engineering company responsible for supplying parts to a number of Formula One teams. “Many people’s view of sailing is as a genteel pastime, but a Volvo 70 is simply brutal and mechanical damage is high on the probability stakes. The PTZ cameras fitted to the mast spreaders have a stainless steel tubular cage to try and protect the cameras from sail battens and rigging. “Dismasting is also a possibility
