Control a FLNG/FPSO Ship to Ship transfer using your Motorola portable radio. Pump START, STOP or READY signals are at the tip of your fingers at all time.
OMTS is an offloading monitoring telemetry system which combines all the North Sea Offshore requirements (Lloyd’s Register) for an oil transfer between an FPSO and a shuttle TANKER. OMTS also fits all the requirements needed for an FLNG vessel.
Requirement
“The control cabin shall be located in a platform providing a good and full visibility on the reeling of the hose. An emergency shutdown switch will also be provided for installation near the spooling device.” extracted from Petrobras requirements on OMTS I-ET-3010.00-1359-960-PY5-001.

Certified by commissioning procedure of the Llyod’s register at Samsung Heavy Industries on June 21st 2021.
In this particular use-case (above), the ship-to-ship liiquid transfer can take place using copper or fiber optics connectors. The UHF/VHF linked is provided as a back-up link.
Ship-to-ship transfer with UHF back-up link
The ship-to-ship physical link (fiber optic or copper wired) can be doubled with a truly wireless (UFH/VHF) solution to cover additional use cases for when the two vessels cannot be bridged due to a malfunctionning connector, or bad weather conditions.
Operations
ESD detection within 2 seconds (FLNG / FPSO side)
LOS detection within 10 seconds (FLNG / FPSO side)
LOS detection under 60 seconds (tanker side)
ESD acknowledgement message within 10 seconds (tanker side)
Automatic hot-swaps between portable radios within 5 seconds.
Portable radios battery capacity 9:30 hours extendable to 12 hours.
HMI panel
The overall Emergency Shutdown procedure can be monitored from the bridge using an imbedded touch panel (SurfaceGo). The touch tablet is embedded inside the control room desktop.
Options
This Portable ESD system can be enhanced with an ESD2 signals to trigger the deluge system onboard the receiving tanker. The system can be wired-up to be used as a primary or secondary offloading monitoring system on either sides of the ship (portside or starboard) or even at the aft of the FLNG/FPSO.
The standard package includes two portable radios, but can be enhanced with additional control points when required.
Electrical integration
The electrical cabinet is mounted in the vicinity of the LNG/oil transfer pump. Connected via dry contact to the control network as a prevention against hacking for example using a Moxa Box.
A straight forward DCS - distributed control system integration is possible via OPC -UA server/client connections.
OMTS CONFIGURATIONS & FEATURES
Ready & ESD
The Shuttle Tanker operators synchronize their operations with the FLNG/FPSO producing facility using a READY Signal. A green-line is established and the transfer pump onboard the producing facility is STARTED. Both the FLNG bridge operator and the Shuttle Tanker operator can remotely trigger an emergency shutdown (ESD) at anytime.
Reference code #1000
Ready & ESD (redundant)
Unlike the previous configuration, this system is made fully redundant. From the power supply, to the radios and the controllers, all systems are redundant.
Reference code #2000
START, READY & ESD
This extra feature allows the FLNG producing facility to START the transfer pump from the VHF/UHF portable radio.
Reference code #3000
DP system
This DP features triggers the ESD when the distance between the receiving and productions vessel is outside of the nominal envelope of operations. (upcoming feature)
Reference code #4000
ESD2 or deluge system
A second ESD signal (ESD2) is used to trigger the receiving tanker deluge system. Such a feature requires a mobile UHF unit to be deployed on the deck of the receiving tanker.

Parallelize LNG offloading operations
When side-by-side offloading is no longer a viable solution
Side-by-side offloading with articulated rigid arms is currently the reference solution for floating liquefied natural gas facilities (FLNG). This cost-effective solution uses mature technologies and procedures that are similar to exposed jetties. Despite the FLNG installation’s close proximity to the LNG carrier moored alongside and the 2.5-meter significant wave height these operations typically encounter, side-by-side mooring provides sufficient offloading uptime for FLNG projects sanctioned to date.
But for future installations — large-capacity FLNGs requiring increased offloading frequencies or those located in areas with persistently harsh environments — side-by-side offloading may no longer be a viable solution.
The industry has proposed several tandem LNG offloading systems that provide significant safety separation distance between the vessels and high environmental thresholds but require use of a dedicated LNG carrier fleet with bow loading systems or long and large-diameter floating flexible LNG lines to reach the midship manifold of conventional LNG carriers.
The Portable OMTS - offloading monitoring telemetry system, is the ideal candidate to establish the green line for operations to start or in case of emergency, trigger an ESD. The receiving tanker operator is physically transported to the tanker carring the portable radios at his belt. His colleague should remain onboard the FLNG and stay in line-of-sight of the tanker. The main control room remains in charge of the cascade of ESDs in case of emergency.
