Caterpillar TAURUS 70 Manual De Usuario

Turbomachinery Package Specification 

 70 Compressor Set and Mechanical Drive 

The Taurus 70 compressor set or mechanical drive package may be operated in offshore 
oil and gas applications. Depending upon operating conditions and movement of the 
underlying support structure, optional package modifications may be required.

 

 

turbomachinery packages operate successfully on the following types of offshore 
installations: 

•  Fixed Platform (FP) 
•  Tension Leg Platform (TLP) 
•  Compliant Tower (CT) 
•  Spar Platform (SP) 
•  Semi-submersible Platform (SSP) 
•  Floating Production Systems (FPS) 
•  Floating Production, Storage and Offloading (FPSO) 
•  Mini-Tension Leg Platform (Mini-TLP) 

Applications are evaluated based on the expected motion severity and the degree of 
package mounting surface flexing. Solar offers the following package modifications to 
achieve successful long-term operation. Refer to Solar’s Engineering Specification 
ES2379 for additional information. 

Gimbals provide protection against G-forces generated by vessel pitch and roll 
movements and against deflection, twisting, and thermal growth of the mounting deck. 
Gimbals may be used for three-point package mounting. 

Anti-vibration mounts (AVMs) are used to isolate the mounting surface from package-
generated vibrations. AVMs do not provide the same level of motion protection as 
gimbals. AVMs may be used for three-point package mounting. 

Moderate or severe package motion can potentially interfere with lube oil system 
operation. To prevent interference, modifications may be made to the lube oil system to 
ensure proper lube oil circulation. 

For moderate and severe duty applications, an inclinometer is furnished to provide alarm 
annunciation and equipment shutdown inputs when maximum allowable angular 
displacements are exceeded. Alarm levels are typically set 2 degrees below shutdown 
levels. 

Certification is typically required to demonstrate offshore turbomachinery compliance with 
applicable rules for a fixed or mobile offshore installation. Solar can provide the 
necessary certification or assist the customer in obtaining certification. Involvement of 
one of the following certifying authorities is usually required: 

•  Det Norske Veritas (DNV) 
•  Bureau Veritas (BV)
