For this project we designed, fabricated and tested
– No.3 External Lifting Tools (ELTs) operated on board of Heerema Thialf costruction vessel. The tools have been designed to grab 3 of 4 tubular legs of the No.2 Murchison platform semi-jackets. The ELTs are hydraulically operated, they can handle tubulars from 1.800mm to 2.300mm and have a maximum lifting capacity of 2.000mT each.
– No.1 External Lifting Tool (ELT) to grab the 4th leg with launch runner, including timber blocks of the No.2 Murchison platform semi-jackets. The ELT is hydraulically operated and can handle tubulars from 1.800mm to 2.300mm and have a maximum lifting capacity of 2.000mT. This ELT has been specially designed in order to allow to operate with the launch runner timber blocks still in place. This tool can be easily modified in the future to handle a standard circular tubular.
