23. 4.

26. PITFALLS OF MODULARIZATION Bad Management Incomplete planning Incomplete planning Material delivery not synchronized with the module assembly Location of module yard Construction begins too soon Construction begins too soon Decisions during construction are made based on construction completion date not on the basis of the potential incurred cost by incomplete or un‐installed components Case study: y •Typical issue like for one module the EHT (Electric Heat Tracing) had not been designed and they were proceeding with the installation of the Insulation. •The modules were going to be finished and shipped in this state. Someone had made the decision that shipping the modules without the EHT but installing the insulation was the best thing to do. •This decision was a typical example of how the modularization concept can turn from a major cost reduction initiative to a disaster. major cost reduction initiative to a disaster •The insulation and cladding will have to be removed and probably wasted because the size will most likely be larger than installed at the yard •The EHT cables will have to be field installed The EHT cables will have to be field installed •The power points and connections and will have to be field installed •Field costs will be exponentially more as compared to the cost of those at the module yard Commissioning and start‐up will be delayed. g p y • The project will see a major cost overrun.
27. INNOVATIVE & CORRECT APPROACH FOR MODULARIZATION Modularization concept must start at feed stage Create a strong integrated Management team for the Detailed design Plan the procurement of materials in the order of assembly Pl h f i l i h d f bl The detailed design must be initiated using the module or modules as the basis and the components and equipment must be designed to fit the module not the module designed to suit the equipment Constructability must be done at the planning stage, e.g. the fabricators and y g module assembly team should be involved at the detailed design stage. g Long lead items must be identified and purchased well in advance Module assembly must be done using the 80/20 rule meaning that the assembly does not begin unless 80% of the module materials have been assembly does not begin unless 80% of the module materials have been received and the other 20% have been purchased and are in the process of being delivered. The module assembly yard should be adjacent to the water to avoid The module assembly yard should be adjacent to the water to avoid shipping constraints in terms of size and weight.
28. INNOVATIVE COST SAVING METHOD FOR MODULARIZATION Standardize the sizes of structural components Meaning that do not over engineer if a common size works, Meaning that do not over engineer if a common size workseven if it is a heaver section than is required the bulk purchase of a common size will result in cost saving g Bulk purchase electrical cable and wire early If there are multiple modules that will be assembled together If there are multiple modules that will be assembled togetheron the vessel, perform all hydrostatic testing in the module yard and use the “In‐Process” inspection system for the joints between the modules. Maximize the work in the module yard and minimize the work performed in the field or on the ship.

38. 6. EXPECTED TRENDS IN MODULARIZATION - PRINCIPLES DRIVING THE MODULEDESIGN…….DESIGN • Safety • Process functions rationale – Central interconnecting pipe rack to feed process modules – Follow logic of flows to minimize piping lengths – Minimize motions of key equipment Minimize motions of key equipment • Modularization philosophy – Well‐defined hull / topsides interfaces – Mechanical completion by function – easier testing & pre‐commissioning – Size / weight of modules selected to enable lifting by conventional means • Addressed technological difficulties Addressed technological difficulties – Process selection / on board floater – Machinery selection – Layout / plot plan / plot plan • Good understanding of technical quantities / cost of facilities • Facility remains « on par » in terms of project magnitude with currently delivered large oil FPSOs • Important commercial potential for medium scale gas accumulations
39. GAS TURBINES GUIDELINESThe Gas Turbine selected has to be referenced as:• Off shore application (FPSO)• Power generation (Electrical motor)• Mechanical driver (High “power density” and efficiency for big compressors) power density• Aero-derivative (high efficiency)• Machine proven reliability
40. LIQUEFACTION TECHNOLOGY SELECTION CRITERIA……• TECHNOLOGICAL SELECTION STRATEGY – Selection of a simple and robust liquefaction process, adapted to medium capacity l f l d b l f d d d and marine environment with high inherent safety – Avoid the use of large HydroCarbon (HC) liquid inventory (such as: refrigerants used in onshore LNG plants) – Minimization of two‐phase flows – Minimization of distillation towers – No by‐products (as LPG) to avoid logistics constraints – Use of proven equipment in identical or similar technologies (gas turbines, heat exchangers…) exchangers ) – For utilities and common facilities (sea water cooling, flare …), stay within capacities already in place in large FPSOs.

41. ACID GAS REMOVAL PACKAGE …….• RECOMMENDED INTERNALS IN MOVING ENVIRONMENT : STRUCTURED PACKING – Trays and random packing are not recommended because of liquid channeling and y p g q g efficiency drops – Structured packing is less affected by tilt and motion thanks to an higher hydraulic resistance to sideways flow• MOTION IMPACT ON STRUCTURED PACKING PERFORMANCES – A permanent tilt has an effect on liquid flow repartition. p q p – Periodic oscillations have a natural mixing effect, less damaging on performances than permanent tilt
42. CRITICAL ISSUES FOR MODULE /EQUIPMENT LOCATIONS…… Q – The column should be located as close as possible from the centre of gravity of the ship to limit liquid maldistribution – Intermediate remixing distributors reduce the consequence of the liquid flow distortion. This leads to an increase of the column length. – Specific distributors, enable to mitigate motion on distribution – experienced vendors to be considered to avoid problems
