Turbomachinery Package Specification Titan 250 Generator Set
15 Marinization
15.1 General Description
The Titan 250 generator sets 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.
15.1.1 Package Sub-base
As a standard, the Titan 250 package is suitable for three-point mounting. In severe
cases, a substructure may be required to provide additional package rigidity to protect
equipment and to maintain proper alignment of the driver and driven equipment.
15.1.2 Gimbals
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.
15.1.3 Anti-Vibration Mounts
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.
15.1.4 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.
15.1.5 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.
15.1.6 Flexible Ducting
Flexible ducting can be provided for the turbine air inlet duct, turbine exhaust duct, and,
enclosure ventilation duct.
