Overview

• Economics for new tanks design or tanks refurbishing

• Universal and multi-products storage solutions with

innovative materials.

• Innovative solutions for enhanced environmental and

safety achievements (0 Emissions).

• Reduced equipment maintenance.

• Shorter construction/ refurbishing time for better R.O.I.


Working Capacity Areas of Impact

• Upper travel constraints

• Depth of floating roof system

• Lower travel constraints

Economics for new tanks design or tanks refurbishing


Dead Stock / Heel Reduction

• What is dead stock / heel?

– Minimum inventory

– Cannot “land” roof

– Represents large working capital

• Behaves like a fixed asset

– However, many maintenance departments do not consider this impact in their decision making process

Heel Reduction Methods

• Minor modifications

– Relocating/replacing nozzles

– Notching pontoon IFRs

– Manway plugs

• Major modifications

– Installation of raised bottom

– Installation of bottom fill/ drain systems

LOWER ROOF

RAISE BOTTOM



Install Manway Plugs

To allow shoe seals to ride safely over manway opening


Relocating or Replacing Nozzles

To allow floating roof to travel lower


Installation of Raised Bottom


• Raise tank bottom = Reduce products heel and dead stock and capital…

• Lower down the floating roof and reduce further the products heel


Bottom Fill or Drain-dry Sump

Conclusion



Benefits of Working Capacity


TOTAL GAINS DUE ONLY TO HEEL REDUCTIONS

AND CAPACITY INCREASES:

For a 90’ (27M) diam tank existing tank.

ADDED VOLUME / FEEDSTOCK = 3, 399 Bbls per tank movement @ 150.00

US$ / Bls = 509,850.00 US$ / per tank movement.

IF: 6 x Tanks movements / Year. = 3,059,100.00 US$ feedstock value / Year.

If 5% GM = NET FINANCIAL GAIN = 152,955.00 US$ / Year

When tank diam. doubles, financial gains quadruple

NET FINANCIAL GAIN= 611,820.00 US$ / Year !!


Universal multi-products storage solutions with innovative materials.

Other Economic Considerations: New technologies

GRP floating roof technology


Key Advantages of GRP Non-corrosive

Capable of withstanding various fuels and chemicals and new agro fuels

Lightweight and low profile GRP is approximately 60-75% lighter than steel, yet it is pound-for-pound stronger leading to more

added volume.

No Maintenance and full guaranteed for life. UV stabilization means no painting or lacquering is required after installation

Impact Resistance and easy “cold”repairs Tests have shown GRP stands up to large impacts, without permanent deformation, saving costly

repairs

Anti Static , Anti Spark, flamme retardant and resistant. GRP is perfectly suited to sensitive environments and new fuels, thanks to its ability to dissipate static electricity and galvanic isolation in conductive fuels (Ethanols…)

No pre-fabrication required and very fast construction times Short lead time, Size independent. Standard material suitable to nearly all products



Cuts construction time by 4 minimum !



0 Emissions = 0 Financial losses !

Seemless external floating Roof

Seemless internal floating Deck



Good practices for agro fuels storage tanks.

Compatible materials:

• Non plated nor galvanized steels, Stainless steels, Bronze..

• Non corrosion passivated steels

• GRP Glass Reinforced plastics, GRP Pipes, neoprene ,

PTFE, polypropylenes, nitriles …

achievements: 0 Emissions).


Reduced equipment maintenance.

- No prefabrication - No welding, no painting. - Full life guaranteed floating roofs - No corrosion - «Cold» repairs tank on duty.


Shorter construction/ refurbishing time for better R.O.I

New roofs in a couple of weeks



Conclusion

Stakeholder Involvement

Traditional stakeholders:

Engineering: Non storage tanks specialists

Procurement: Short sighted CAPEX decisions

Tank contractors: Steel contractors. No knowledge in new

materials and technologies.

Project Manager: Pure construction minded.

Proactive approach requires broader team:

Operations / Production

Finance

Maintenance

QA / HSE:


Conclusion

Advanced Planning / Timing

Minor modifications

• Lean and mean technical specifications

• Pre-plan to identify any capacity opportunities, heel reductions.

• Pre-plan to identify operations wish list from concerned stake holders

Major modifications

• Lean and mean technical specifications

• Requires earlier planning

• To evaluate and gain consensus from all stakeholders

• To ensure proper budgeting and R.O.I. evaluation
