Titan 250 Generator Set

 

 

15 Marinization

15.1General 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.

15.1.1Package 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.

15.1.2Gimbals

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.

15.1.3Anti-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.

15.1.4Internal 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.

15.1.5Inclinometers

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.

15.1.6Flexible Ducting

Flexible ducting can be provided for the turbine air inlet duct, turbine exhaust duct, and, enclosure ventilation duct.
