Turbomachinery Package Specification Taurus 60 Compressor Set and Mechanical Drive
16 Marinization
16.1 General Description
The Taurus 60 Compressor Set and Mechanical Drives 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.
Solar
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.
16.1.1 Gimbals (Optional)
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.
16.1.2 Anti-Vibration Mounts (Optional)
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.
16.1.3 Internal Package Modifications
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.
16.1.4 Inclinometers
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.
16.1.5 Certification
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)
