through. The parameters for the development of these cus- tom barriers included set size limitations, the ability to handle heavy loads, and withstand years of forceful vibrations and blistering salt spray typical in the North Sea. Working togeth- er, the parties employed a custom-designed barrier system with the ability to absorb energy from impacts several times higher than traditional barrier designs without any energy absorption functions that are usually found on oil rigs.
Shocks and Buffers ITT Enidine’s Heavy Duty (HD/HDN) Series Shock Ab- sorbers and Jarret Series Buffers are an essential part of the barrier engineered by Aibel AS (Stavanger, Norway) for the Gudrun Platform. (Aibel is one of the largest Norwegian gas services companies that engineers, builds, maintains and modifi es oil and gas production facilities.) The barrier includes highly tuned dampers that absorb the cargo’s kinetic energy. These solutions make cargo safer to maneuver,
Series Buffers decelerate the energy capacity loads, which can be up to 1000 kJ per cycle for some applications, helping crane operators safely pick and place cargo aboard the platform so neither cab nor trolley slam into the end of their respective tracks when moving across the container yard. The shocks of the HD/HDN series include an air-charged bladder accu- mulator—which replaces mechanical return springs—that provides a shorter length and reduced weight compared to competing products. The zinc-plated or painted skin on the shock absorb- ers gives an added layer of protection against corrosion, especially where equipment is exposed to ocean air and sea spray. The shock absorbers have a broad operating range, from -40oC to 100oC. This temperature spread fully brackets the environment in the North Sea, ensuring that the shock absorbers are well suited to this application.
These shocks are just one kind of ITT Enidine heavy-duty industrial shock absorber. The full line includes a wide variety of confi gurations, including bellows, clevis mounts and safety cables. All are fully fi eld repairable. The Jarret Series Buffer was designed specifi cally for handling heavy loads found at steel mills and railways and in marine, defense and aerospace industries. For this project with Aibel, a customized version of this buffer was designed to be used on barriers for oil platforms to prevent damage to cargo when moving with high winds and rough seas. The buffer was also designed to have a lifetime of up to 20 years.
Decreased Employee Injury and Cargo Damage The Gudrun’s crane operators move cargo containing food and heavy, expensive equipment for drilling. The barriers on the platform not only protect this cargo while it’s being maneuvered, but employees on the platform, ship and oper-
