SITE AUTOMATISM

LARCO has been specialising in developing safety and process PLC and setting up supervision services for more than seven years.

LARCO has its own team of automation engineers. We have thus been able to introduce writing, archiving and non-regression of version procedures to develop reliable modules.
We have the following development tools :
• ELOP II Factory
• TIA PORTAL
• PSS4000
• Unity PRO XLS
• PC VUE

A consistent, upgradeable and structured modular set of software applications for product movement safety and automated management.

Implementation of associated SIL process and safety automatism.

Taking into account of specific sensors and of actuators.

OUR PROCESS AUTOMATISM

RECEIPTS BY PIPELINE

Dialogue software application used to secure, make reliable and desynchronise product receipts by pipeline, requires motorised valves.

RECEIPTS BY SEA

Dialogue software application used to secure, make reliable and desynchronise product receipts by sea, requires motorised valves.

RECEIPTS BY RAIL

Dialogue software application used to secure, make reliable and desynchronise product receipts by rail, requires motorised valves.

PUMP CONTROL

Software application for secure, optimised control of pumps; allocations can be changed without modifying control cabinets, tank lines or running pumps in parallel.

VALVE CONTROL

Software application of instrumentation and control of wired or bus motorised valves. Control of unexpected movements, order execution, operations storage and statistical processing.

WEB CONTROL

Software application for remote reporting via the Internet (web server) of safety or site operation information. Use of a standard browser with no need to configure the PC specifically.

ADDITIVATION, DYEING

Software application for injection of an additive or dye at receipts of products, inter-tank transfers or shipments by pipeline. Often combined with a skid or injection kit. Rate of 1 ppm to 3200 ppm.

GAUGING SYSTEM

Software application for supervising gauging systems and incorporating results into the site safety or operating applications.

BIOPRODUCTS

Software application for mixing petroleum products at receipts of products, inter-tank transfers, shipments by pipeline or tanker loading operations. Often combined with an injection arm. Rate of 5% to 85%.

NOS AUTOMATISMES SECURITE

ANTI-OVERFLOW

Software application for processing SIL2 or SIL3 level alarm equipment, potential use of an API SIL.

ANTI-MIXING

Software application controlling the suitability of the characteristics of the product delivered by the shipped with those expected by the receiver, potentially combined with the following equipment: Density meter, dye meter. Can be used at receipt or delivery.

LEAK DETECTION

Software application for detecting an accidental leak when transferring product by pipeline, taking into account liquid hydrocarbon detection instruments in the tank, pumping station, settling tank, etc. and metering or gauging instruments.

REMOTE MONITORING TRANSFER

Software application for remote transfer of site safety or operating information by specialised line. Voice alarm on GSM.
