Catalogue excerpts

SeaHaven Pontoons The SeaHaven is a classic marine pontoon system with an enviable reputation for durability. It can be relied on to provide a safe haven for leisure and commercial craft; the system being specifically designed for marinas in inland waterways and less exposed locations. Developed over 35 years’ experience derived from challenging sites, these pontoons are trusted by specifiers, designers and users alike. Using a combination of robust steel sections, in an allwelded construction, gives the finished unit superb stability and torsional strength. Inverness Marina, Scotland Each float is fully interchangeable and polystyrene filled. They are of a heavy duty construction; rotationally moulded to provide the necessary buoyancy whilst remaining resistant to impact damage, frost and long term decay. Access for repairs and maintenance is gained simply by removing the decking sections from above. Just four securing bolts releases each float for exchange or inspection. Interconnections are achieved by utilising 4 No. heavy duty rubber blocks combined with heavy M24 bolts and nyloc threaded nuts. This arrangement gives excellent lateral and vertical movement whist maintaining high performance in compression and tension. Noise is virtually eliminated. As standard, the pontoons are available in widths of 2, 2.5 & 3M and lengths of 7, 10, & 12M. Bespoke sizes can be achieved and specially strengthened versions are possible where high loadings such as bridge landings and commercial pedestrian traffic is likely. Simple and elegant service access covers run along both sides of the pontoons providing easy unhindered access to cabling and other services. A specially developed access system allows simplified drop-in deployment of entire cable lengths from above, reducing installation time and cost. Quality Management
