API 2350 edition 4 – Released May 2012 API 2350 is by the industry a

jointly developed standard for overfill protection for storage tanks in petroleum facilities

API 2350 is a description of the minimum requirements to comply with overfill prevention best practices

API 2350 is based on other safety standards such as IEC 61511

API 2350 is intended to be equally valid & applicable worldwide

API 2350’s main purpose is to prevent overfills, but increased operational efficiency & higher tank utilization are common results of applying the standard

Certified vs Proven-in-Use

Path #1: Selecting Certified Sensors

– Manufacturer has developed the sensor as per IEC 61508 standard

• Certified by external agency (e.g. Exida, TÜV)

• Certificate with failure statistics

• Safety Manual

– Pro’s for the user

• Designed for safety

• Ready-to-go, no additional work

– Con’s for the user

• Few suppliers with certified sensors

Complying with IEC 61508, Certified

devices is a major task for the

manufacturer

Certified vs Proven-in-Use

Path #2: Selecting Proven-in-Use Sensors

– User needs to prove the sensor suitability as per IEC 61511 standard

• Consideration of manufacturers quality, management & configuration management systems

• Adequate identification & specification of sensor components or subsystems

• Demonstration of performance of components or subsystems in similar operation profiles & physical environments

• The volume of operating experience

– Pro’s for the user

• ?

– Con’s for the user

• Considerable amount of extra work

• Responsibility

Complying with IEC 61511, Proven-in-

Use devices is a major task for the

user

Is Your Floating Roof Really Floating?

– Issue: Floating roofs (internal/external) can get stuck and collapse with devastating consequences causing:

• Hydrocarbon vapor releases

• Potential full surface fires and explosions

• Large mechanical damages

• Huge negative environmental impact

• Substantial financial losses

• Loss of property and ultimately loss of life

– Need: To measure how even the roof floats on the liquid surface and to detect early tilt indications cased by:

• Increased rim seal friction (dual & triple seals are becoming increasingly popular to minimize vapor emissions)

• Leaking/punctured pontoons (today high risk manual inspections are required walking on the floating roofs)

• Heavy rain/snow buildup & clogged drains

• Strong winds

Roof Tilt Measurement Solutions:

– A: To use 3 additional radar gauges mounted 120 degrees apart measuring the floating roof

• Tracks the roof in three spots with reference to the still-pipe level gauge

• Difficult installation and expensive solution

– B: To use three wireless GWR’s mounted on the floating roof using existing roof-leg nozzle openings and communicating with the existing or new wireless tank farm network

• Tracks how the roof floats in three spots

• Cost effective and easy to install on open floating roof tanks (internal floating roof’s will require permits & planning)

[File Name or Event] Emerson Confidential 27-Jun-01, Slide 16 Rosemount Tank Radar AB Confidential

Three wireless battery powered Guided Wave Radar’s (GWR’s) mounted directly on the roof. Ex in the roof leg nozzels 120 degrees apart

Measures how deep the roof floats

Comparison between the three measurements provide input on how the roof floats

Configurable alarms indicate when an action is required

Connects to the wireless tank gauging system, no additional network required

Roof Tilt Measurement Wireless GWR Solution

Cost effective way to check that your

floating roof is really floating !

Keeping on-line track of the roof position

– Enables early warnings if something starts to change with the tank roof conditions

Minimizing the need for maintenance personnel to enter the tank and the tank roof for inspection

– Some users report that they have procedures to visually inspect by climbing the tank, ONCE a week!

Easy installation

– Even with tank in service
