Mooring System (Package)
This mooring winch package consist of: One electric 100 tonne double drum winch with combined mooring

emergency storm anchor drum with auto spooling
Three (3) electric 100 tonne double drum mooring winches with auto spooling.
Four (4) deck mounted local control stands c/w tarpaulins
One (1) central control panel and display
Four (4) variable frequency drive cabinets c/w resister banks
One (1) PLC cabinet with transport top frame c/w rigging.
Eight (8) fixed upper turn down sheaves c/w gypsy wheel chain winch for lift / lowering sliding swivel fairleads
Eight (8) sliding swivel fairleads, with mechanical locking in lower operational position
Four (4) winch integrated double electro‐hydraulic power units for winch failsafe brake, dog drive clutches, positioning of travelling swivel fairleads and locking in upper storage positions

Eight (8) chafe chain 58mm grade U2 x 5.1m long
Each winch drum has a capacity of 1200 feet of 2 inch wire, 100 tonne pull and 180 tonne brake hold on the 1st layer. The mooring / storm anchor has a braking capability of 150 tonnes on the 6th wire layer
The winch has a 440V / 3 Ph / 60 Hz electric motor prime mover driven by a variable speed drive system
Each double drum winch has a local control console and there is a remote control console for all eight winches. Control units have electronic readout of line tension and speed of all anchor handling mooring winches, as well as various other health monitoring parameters
Each drum has been supplied with a fixed overboard sheave and a swiveling fairlead which can be raised from its operational position below the water level to allow the anchor to be brought clear of the water during transit

High-Pressure Choke Manifold
Overview: The high-pressure choke manifold provides well intervention capability via a capping stack. The choke manifold can control the flow of hydrocarbons directly from the well to the process for flaring. Primarily designed for 10,000psi capability.

Processing
Overview: The 3 phase process separates water from gas and oil. Glycol process heaters provide heat to the process and a chemical injection system introduces anti-foam and demulsifying agents to the system.
