Experts in Deepwater Installation.InterMoor offers a comprehensive range of mooring solutions thatrange from simple conventional catenary installations to taut-legpreset systems over valuable subsea infrastructure and coupledsystems used to connect two or more vessels in close proximity.InterMoor has led the industry in the use of deepwater presetmoorings. With suction anchors, our patented SEPLA anchor, polyesterrope and taut-leg moorings, InterMoor has dramatically improved theefficiency and depth capability of deepwater floating structures.Most suction anchors used around the world today have been designedby InterMoor engineers. And our unique Suction Embedded PlateAnchors save operators more than 50 percent in total project costs.SEPLA advantages include:• Precise anchor location (both in plan and depth)• Simple plate construction• Smaller, less expensive anchors• More efficient than suction piles• Economical fabrication costs (a fraction of anequivalent suction pile installation)9
