The guying system is the feature that most distinguishes the Lena guyed tower from a conventional fixed-bottom platform. Special equipment and procedures were required to handle and place 6-foot diameter anchor piles, 200-ton clump weights, and both 5-inch and 5 3/8-inch diameter guyline segments in 1000 feet of water. Many procedural alternatives were evaluated for each discrete step of the guying system installation. Various equipment concepts were studied for each alternative. The cost of each option was determined and the compatibility with all other options was assessed. The most reliable and cost-effective alternatives were selected for the final installation plan, which will be discussed in this paper. The effectiveness of the installation planning was verified by the success of the Lena installation. The unique equipment proved to be reliable and the efficiency of the newly developed offshore construction methods was demonstrated.
