FPSOs with LESER safety valves
Safety for new frontiersSafety for new frontiers
Due to the trend towards oil production from remote or deepwater locations, FPSO (Floating Production Storage Offloading) units are increasingly used in the upstream Oil & Gas Industry. Safety is a primary concern on an FPSO. Safety valves are used on FPSOs to protect the different topside modules for:
• Oilandgasseparationandtreatment• Compression• Waterinjection• Powergeneration,andotherprocesses
FPSO applications have special requirements to safety val-ves. They result from the diverse media and processes on an FPSO and the environment in which the FPSO operates:
• Sea water or seawater / hydrocarbon emulsion as a protected medium: Valve materials must be resistant to corrosion to enable longer service intervals and to ensure the operational reliability of the safety valve.• Sourgas(H2S) service: Valve materials must comply to NACE specifications• Offshoreenvironment:Valveshellmustbemade from corrosion-resistant materials or adequately coated• Approval of the relevant classification societies (DNV, ABS etc.)
Also in logistics, FPSOs have special requirements because they operate globally. Spare parts and replacement valves must be available around the globe with very short lead times.

The LESER Industry Solution for the specific operating conditions on FPSOs consists of three elements:
1. Corrosion protection concept
Mainly Duplex and Super-Duplex materials are used for corrosionresistance.WiththeAPIAlloyConcept,LESER offers these materials in efficient configurations and short lead times. Only the parts required by the specific
application are made from Duplex materials. For different applications, there are different levels.Besides Duplex materials, also nickel-based materials likeMonel,HastelloyandInconelareavailableintheAPIAlloy Concept.NACE-compliant valve configurations can be ordered easily with Option Codes for all valves.Coatings for marine environment are available, such as multi-layer and epoxy coatings.

2. Classification society approvals
LESER safety valves are type-approved by leading classification societies. The table below shows some of them.
•DNV-DetNorskeVeritas
•GL-GermanischerLloyd
•BV-BureauVeritas
•LROS-Lloyd‘sRegisterofShipping
•ABS-AmericanBureauofShipping
•U.S.CoastGuardClassification
•RINA-RegistroItalianoNavale
•ClassNK-NipponKaijiKyokai
In addition, third party inspections by classification societies e.g. for set pressure are possible. Thanks to the experience of LESER, these inspections can be conveniently ordered through an Option Code.
3. LESER Order Services (LOS) and spare parts
LESER understands the need of FPSO operators and shipyards for quick supply of valves and spare parts when an FPSO undergoes repair or retrofitting. Therefore,
LESER Order Services (LOS) offer customer-oriented supply chains with easy ordering and quick delivery. Ordering channels and delivery times can be designed around your needs.
Efficient and quick supply is ensured by more than 25 local stocks and assembly around the world and Spare Part Kits for many valve types.
