KEY LOCATIONS

� Trends in Floating Production Market.

� Advantages of Floating Production Facilities.

� Factors Affecting Life Extension & Redeployment.

� Life Extension & Redeployment Options:

� Same Field.

� Different Operating Area.

� Long/short term lay-up.

INTRODUCTION

� Crude oil composition, gas/oil/water ratios, production volumes and duration.

� Can all have a Significant Impact on the functional specification (topsides

weight, power requirements, field life, corrosion protection etc.) .

� No such thing as a standard FPSO – certain modifications required for each

new production application.

CRUDE ASSAY & PRODUCTION PROFILE

� Essential that basis of design is clearly understood at the outset.

� Hull Elements.

� Production Facilities.

� Mooring System.

TECHNICAL ASSESSMENT

� Depends greatly on how the unit has

been operated.

� Fatigue Assessment.

� Rotating Equipment & Pipelines.

� Thickness Gauging.

� Surveys.

ASSET INTEGRITY

� Interface between Equipment Modules

and Hull Structure.

� Important due to Significant Topsides

Size and Weight.

� Stringent Noise Limits now Apply to

Accommodation Area.

INTERFACE STRUCTURES, NOISE & VIBRATION

� Insulation such as asbestos are still

present on many units.

� Decision to encapsulate or remove.

� Asbestos Management Plan.

� Adoption of high standards of

collision protection.

� Use of Sponsoons, Collision Frames & Internal Strengthening on Side Shell.

HARMFUL SUBSTANCES & COLLISION PROTECTION

� Challenges such as Deck Space Limitation, Power Availability.

� Changes to Process Performance Requirements.

� Regulatory Changes Specific to Floating Units.

PERFORMANCE STANDARDS, REGULATORY COMPLAINCE

� Critical towards the success of any life extension / redeployment project.

� Will influence the scopes that may be achieved, methodology and

operational issues.

� Factors such as statutory inspections, class survey cycles and material

availability are to be considered.

� Effective Planning minimizes disconnection time and loss of production.

PROJECT EXECUTION STRATEGY

� The Floating Unit will most likely be towed

to the intended location (unless it has

its own propulsion system).

� Attention to structural loading as towing

period may undergo the most severe

loading condition.

� Manned or Unmanned.

� Weather Impact on tug efficiency and

effective bollard pull.

TRANSPORTATION ASPECTS

� Safety, Security and Assurance for

Units Removed From Location.

� Exposure such as

� Breaking Free of Mooring.

� Fire.

� Watertight Integrity.

� Collision.

� Frequent follow up and inspection

as opposed to “lock and leave”.

� Seek same level of support

engineering & documentation

as other phases of asset lifecycle.

LONG TERM LAY-UP ISSUES

� Early Termination of FPSO lease contracts

has been an area of potential legal dispute.

� Termination for cause or convenience.

� Independent Reviews conducted in

advance can save time and money

compared to lengthy arbitration processes.

� Decisions on redeployment are key areas of underwriter exposure.

CONTRACTUAL CONSIDERATIONS

� Unique Construction, Modification &

Operating History.

� Fast tracked FSO Life Extension to

increase design life by 6 years.

� Actual structural details were different

from drawings in several locations,

presenting an engineering challenge.

� A total of 260 tonnes of Steel

replaced at Remontowa Shipyard,

Poland.

� An example of how early preparation

is key.

CASE STUDY (APOLLO SPIRIT)

� Engineering Support towards Decommissioning

of Nautica Muar FSU & redeployment of

Mampu 1 FSO.

� Limited storage capacity main driver for

decommissioning.

� Currently being executed and various types of

engineering analysis and assessments were

required before the project could commence.

CASE STUDY (NAUTICA MUAR DECOMMISSIONING)

� Drivers for success include:

� Proper Scope Management.

� Safety & Risk Management.

� Firm Communication Protocols.

� Effective Management of Change.

� Clear Definition at the outset.

� Collaboration & Communication.

� Floating Units have the right level of flexibility.

� Effective Redeployment of units can be more attractive than new build units

provided that the associated risks are identified and managed.

� Critical to ensure that the marine assurance aspects are adequately

covered.
