Since 2010, bollard pull testing has become standard practice for newly built steel tugs. The test provides a good measure of the tugboat’s maximum pulling load. Contacted to supply a bollard pull test rope at short notice, Lankhorst supplied a 88 mm diameter, 300 m LankoForce rope made from high modulus polyethylene (HMPE) Dyneema. The rope has an actual breaking load of 4806 kN (490 mT) (spliced).
Based in Ravenna, Italy, Rosetti Marino specializes in PSV’s designed to provide assistance to offshore oil platforms and safely transport equipment and material to and from the platforms, even those located in very rough waters, such as the Baltic Sea and the North Sea and particularly in adverse weather conditions.
“Lankhorst was able to supply the new rope within 3 weeks ensuring we were able to meet our scheduled bollard test date,” said Luca Mazzotti, Procurement and Subcontracting Dept, Rosetti Marino. “The increasing power of today’s tugs makes bollard pull testing vital. In this case the LankoForce rope was needed to test a multifunctional anchor handling, tug, supply and service vessel with a bollard pull of 220t, the most powerful vessel we have built in this class.”
