Penetration Force

Small-scale field tests on a monopod suction pile with and without the detachable penetration apparatus (DPA) and tripod suction buckets have been performed. One of the objectives of the field tests was to identify the capability of the DPA at small-scale and to obtain useful information for planned future full-scale field tests. The DPA which has been developed to control and increase the accuracy of the verticality of monopod suction piles during installation. In addition, it can also contribute to increase the penetration force under certain conditions. Included in this paper are the details of the small-scale field tests, including the site conditions, suction pile details, DPA details, installation, instrumentation equipment, and test results. Results indicate that the tripod suction buckets have a significant advantage over the monopod suction pile for verticality control and that the newly developed DPA is fully capable of enhancing the verticality control of the monopod suction pile during installation.

Modes Of Vibration

This paper presents the results of full-scale field tests on two steel guyed latticed towers. The towers were approximately 83 m in height, were guyed at three levels, and were of bolted angle construction. The observed results consist of the natural frequencies of the first two modes of vibration as well as the damping ratio for the first mode. The observed results are compared with analytical predictions and observations made concerning the contributions of structural and cable action to the damping ratio.

This paper describes the first full-scale field test of a steam injection system for a natural-gas-fired G.E. LM5000 gas generator for the purpose of: (a) decreased exhaust emissions, (b) increased power output, and (c) improved efficiency. It discusses the steam supply system, engine features, test results, and plant economics for steam injection into the combustor and compressor discharge sections of the LM5000 at rates up to 65,000 lb/hr (29,510 kg/hr).
