MORDEC™ ANCHOR CHAIN & FITTINGS MORDEC™ Next Generation Chain Solution The proportion and configurations of our present day stud link chain systems was adopted by Lloyds in 1858, after years of usage, that it would be maintained at 15 fathom (Imperial measurement) or 27.5mtrs as a standard length to be connected by connecting elements. However, many chain systems failed due to the high fatigue rate of the connecting elements. Thus, according to offshore standards, connection elements are considered as “weak” links and not recommended in long term mooring systems. In fact, longer lengths have...

Devil's Claw Chain Stopper The Devil's Claw Chain Stopper Assembly is design primarily to assist in securing the anchor at the hawse pipe. Additionally, it can be utilized to help retrieve mooring components. The size of the claw and the jaw opening arc directly proportional to the chain size which is to be engaged, when the stopper assembly is used to secure mooring chain neither the stopper nor the chain is place in a bending condition; instead, the loads arc arranged inline. Each component of the assembly is forged alloy steel which is heat treated to develop a tensile strength of 150,000...
