Calculations are based on a drag force formulation, suitable coefficients being established from model tests or computational fluid dynamics. The global floating production system market is expected to rise with an impressive CAGR and generate the highest revenue by 2026. The standards are typically divided into a number of sections as follows: A further description of certification standards is given below for one particular authority. The process plant on the vessel can handle about 19,000,000 cubic metres per day (670,000,000 cu ft/d) of gas and 13,500 cubic metres per day (480,000 cu ft/d) of oil.

Cuneyt Capanoglu, in, This section specifies the design requirements for the flexible jumper, and describes the calculations of the loads acting on the, Marine Petroleum (Gas) Engineering and Equipment, gives a comprehensive discussion of model testing techniques for, Mooring System Engineering for Offshore Structures, The most common types of mooring profiles used for, Most of the Mobile Offshore Drilling Units and some, “Recommended Practice for Design of Risers for, Subsea Pipeline Design, Analysis, and Installation. The floating production, storage, and offloading systems (FPSOs) have been used in offshore production since the 1970s—typically in the North Sea, offshore Brazil, Asia Pacific, the Mediterranean Sea, and offshore West Africa (Angus, 2009). Figure 8.32. 5.2.1 Flare and vent system. When the direction of the environment is not favorable, shuttle tankers may have difficulty approaching and staying connected to the FPSO. The term fSi represents the probability density of peak to trough nominal stress ranges for the individual state. The first term is the Froude–Krylov force, i.e. This might involve thousands of cases covering, for example, hindcast conditions every 6 h going back 10–20 yr at the specific site. Both chain–polyester–chain and chain–wire–chain should be considered. For vessels that cannot change direction relative to the weather it is necessary to consider waves, wind and current acting from the same directions. We design, manufacture and deliver unique Floating Production System swivels to meet the demanding requirements of offshore operators worldwide. Both all-chain and chain–wire–chain should be considered. Built at a cost of over US$ 800 million by Hyundai Heavy Industries in Ulsan, Korea, it is operated by Esso Exploration Angola (ExxonMobil). Dry trees are possible on a TLP because the platform is heave-restrained by vertical tendons, or tethers. Oil has been produced from offshore locations since the late 1940s. A more rigorous method for specifying environment is to perform a “response-based analysis,” see for example Standing, et al (2002). In addition, the spread moored FPSO has the main disadvantage of lower availability for offloading operations than the turret-moored FPSO [1]. Large capacities of steam, hot-water or thermal oil are required for the processes onboard Floating Production Systems. Products for FPSO and FSO units. 1.5. From: Handbook of Offshore Engineering, 2005, Jim Britton, Matthew L. Taylor, in Trends in Oil and Gas Corrosion Research and Technologies, 2017. In an individual sea state the fatigue damage di is given by: where the number of stress cycles, ni, is calculated from the product of the mean up-crossing rate of the stress process (in Hz), the probability of occurrence of the sea state, together with the mooring system design lifetime in seconds. This is taken as πd2/4 for steel wire rope and 2πd2/4 for chain. The FPSO conversion was carried out at MMHE Shipyard Pasir Gudang in Malaysia, while the topsides were fabricated in modules at various international vendor locations. Figure 29.4 shows a flexible jumper being installed. This pod is called a “submerged Christmas tree,” or simply a “wet tree”. The EPCI contract was awarded in October 2007 and production started in early 2012. For catenary moored structures, the restoring stiffness contributions to the wave frequency motions from the mooring and riser system are ignored in deep waters, though must be investigated for water depths below 70 m. For the taut moored structures, the restoring forces from the mooring and riser system must be addressed to establish whether they influence motions at wave frequencies. [3] Originally, all oil platforms sat on the seabed, but as exploration moved to deeper waters and more distant locations in the 1970s, floating production systems came to be used. Factors, such as increased offshore exploration activity and focus on development of offshore oil and gas production, are expected to drive the market for floating production systems. Taut (or semitaut) leg system with a chain–wire–chain setup. 4.1): Figure 4.1. FPSOs are preferred in frontier offshore regions as they are easy to install, and do not require a local pipeline infrastructure to export oil. We will not repeat the discussions there, but will summarise the practical implementation for Global Strength analysis. Current forces will increase, if the water depth is typically less than three times the vessel draught, OCIMF providing relevant enhancement factors. For ship-shaped floating vessels with spread moorings, the mooring lines are connected at the bow and stern and spread outward, which can restrain the lateral offset and heading of the hull. A consequence of this is that floaters may be designed with excess capacity for a given reservoir, in effect adding an “option cost” into the facility investment banking on future tiebacks from additional reservoirs. On the other hand, the mooring lines can often be grouped into three or four groups to improve the mooring performance and to create large angular space for risers and other subsea facilities. Data on mooring chains and associated connecting links and shackles is also provided. Manual and automatic remote thruster systems. MODEC is an owner/operator and EPCI (Engineering, Procurement, Construction and Installation) general contractor of floating production systems including Floating Production Storage and Offloading (FPSO) units, Floating Storage and Offloading (FSO) units, FLNGs, Tension Leg Platforms (TLPs) and Semi-Submersibles. Waves provide three loading mechanisms acting on the floating vessel. Deepwater floating production systems are generally concentrated in the “Golden Triangle” of the Gulf of Mexico, offshore West Africa and Brazil (fig. A production spar typically uses 9 or 12 mooring lines in three groups connected from the outer shell of the platform to the seabed. The research report on Floating Production System (FPS) market contains an in-depth assessment of the growth driving factors, opportunities, and restraints impacting the regional terrain and competitive arena of this business sphere. The mooring analysis should ideally consider line dynamics, i.e. Bittern, Guillemot West, Guillemot Northwest, This page was last edited on 12 January 2021, at 09:48. Many internal spaces are protected with zinc rather than aluminum anodes to alleviate some of these issues; it is a good idea to consider the placement of permanent reference electrodes in such spaces as access can be difficult after commissioning. The processing equipment aboard the floating production and storage system is similar to that on a production platform and can consist of water separation, gas treatment, oil processing, water injection, and gas compression, among others (Figure 3.4). A group of engineers in California invented a floating system in the early 1970s, which could be tethered to the sea floor, effectively making it a tethered compliant platform [Horton, et al 1976]. Additionally Lloyds, NMD, NPD and IACS provide similar rules and design information. The types of production concepts available for deepwater production are illustrated in fig. These can result in a doubling of the deepwater motions for large wave periods in a very shallow water. Floating Production Systems Quarterly Released three times a year in March, June, and December, the Floating Production Systems Quarterly provides in-depth project by project analysis and tracking. In general, catenary systems require a larger R/D ratio (anchor radius/water depth) than taut leg systems. A FPS is typically a large ship equipped with processing facilities and moored to a location for a long period. The deep draft Spar platform is not heave-restrained, but its motions are sufficiently benign that risers can be supported by independent buoyancy cans, which are guided in the centerwell of the Spar. of Energy, HMSO, 1984 and takes precedence over “Code of Practice for Fatigue Design and Assessment of Steel Structures,” BS7608:1993, with or without amendment of February 1995). However, if, for example, current and wind are the dominant features, such as Gulf of Mexico conditions with loop currents and hurricanes, then 10-yr sea conditions combined with 100-yr current and wind should be assessed. The stress ranges are obtained by dividing the line tension ranges by the nominal cross-sectional area. Vessel offset in extreme conditions for taut leg systems are typically small at around 5% of water depth, while catenary systems have much larger vessel offsets. Adding to the economic advantages of these systems, existing tankers are frequently converted into FPSOs (Pelletier, 2000a,b). For rigid riser operations, offsets are limited by the maximum allowable riser angle at the BOP flex joint, and must also allow for heave compensation equipment. Manufacturers’ limitations must be considered for flexible risers and steel catenary risers. Generally there is a lack of documented fatigue data on these latter connection elements, though API RP 2SK does provide fatigue information on Kenter shackles. These are often referred to as clustered-spread mooring systems. DNV OS-E301 presents data in the form [API, Chaplin, 1991]: where nc(s) = number of stress ranges, s = stress range (MPa), aD = intercept of the S–N curve, m = slope of the S–N curve. [22], As of August 2015[update], there are more than 277 Floating Production Units in use around the world, of which 62% are FPSOs. 5.2.3 Inert Gas Systems 6. Furthermore, because these systems can be moved, they are a more economical solution for more marginal fields, as the vessel can be moved to another development and redeployed once the original field has been depleted. This gave rise to what is called the Tension Leg Platform (TLP) [Horton, 1987]. Aker Solutions (formerly Aker Kvaerner) developed the front-end design for the floating production facility as well as the overall system design for the field and preparation for procurement and project management of the total field development. The Floating Production Systems Market Report to 2018 presents a comprehensive analysis of this increasingly important sector of the offshore oil and gas industry. Thrusters can consist of both fixed and rotating configurations and be of variable pitch and speed. Oil Terminal "Belokamenka" L.L.C Rosnefteflot, Rubicon Offshore International with Langstein Slip. Fixed and compliant platforms were safe for this kind of production because they could protect the well casings from the environment. Further discussion on concept selection is included in Chapter 7. The EPcma contract covers detail engineering and procurement work for the FPSO topsides as well as construction management assistance to BP including hull and topside facilities. It is common to use two or three environments including the 100-yr wave with associated wind and current, and the 100-yr wind with associated wave and current. Classification Rules or Offshore Standards are invoked, if the owner of a platform elects to have the platform classed. For new lines, the standards indicate the following drag coefficients: Cd = 1.2 for spiral strand with sheathing. By continuing you agree to the use of cookies. 5.1.3 Ballast water system. It has wire rope and chain connections to an anchor, or it can be dynamically positioned using rotating thrusters. Floating Production Systems (FPS) We design, manufacture and deliver unique Floating Production System swivels to meet the demanding requirements of offshore operators worldwide. Frequency domain is efficient and fast but may not capture some important non-linearities such as gravitational loads from large heel angles. The field is located in the Bay of Campeche, offshore Mexico's Yucatán peninsula. This method employs a simplified mathematical model of the platform and mooring responses to various environmental conditions. This can be problematic because the anodes are by definition hard to replace in these inaccessible areas. For fibre rope, the capacity against fatigue caused by tension–tension effects is given by: where R is the ratio of tension range to characteristic strength and m, aD are given in the standards. This section specifies the design requirements for the flexible jumper, and describes the calculations of the loads acting on the Floating Production System (FPS) hull and on the forging beneath the buoyancy tank. No up-lift is allowed for the ULS, but up-lift may be allowed for the ALS, if the vertical loads do not impair the anchor-holding power. [22] The hull is an Aker Solutions proprietary "Tentech975" design. Stoner, et al (2002) outline additional work necessary before fibre moorings can be used at harsh weather locations. Use of all-weather production risers, so that outside of maintenance and emergency, they needn't break off and lift out. At the calm sea area, oil can directly send to the oil tanker from the production platform, which will reduce investment. jumper loads. These facts motivated operators to seek floating platforms, which could support Christmas trees at the surface, “dry trees”. The first 3 FLNG's were constructed in 2016: Prelude FLNG (Shell), PFLNG1 and PFLNG2 (Petronas). Figure 7.106 and Equation 7.72 show the application of the modified Morison equation to a member of a floating structure. For example: A drilling semisubmersible typically uses 8 or 12 mooring lines in four groups connected from the four columns to the seabed. [4], The first oil FPSO was built in 1977 on the Shell Castellon field, located in the Spanish Mediterranean. There is a growing trend towards third party ownership of the floating facilities, which opens the possibilities of several operators sharing production through one facility [Anonymous, 2003]. During these dry docks, repairs are made to the coating and CP (usually ICCP) systems. where f→= force per unit length normal to centerline of the cylindrical element, p = fluid pressure on the surface of the cylinder computed as though the member does not disturb the flow, ρ = density of water, Ca = added mass coefficient, Cd = drag coefficient, u→=n= resultant velocity normal to the element centreline, a→=n = resultant acceleration normal to the centreline. Once the anchors are deployed, the position and direction of the floating vessel are effectively restricted, and risers and umbilical systems can be installed and operated. The design equations to be used for ULS and ALS are based on the concept of partial safety factors (see Chapter 5). Presence of mean stress for non-welded components, Ovality and mis-match causing hi-lo conditions at the weld. Unlike wells on fixed platforms and on land, subsea wells do not allow operators to have direct access to the wells for maintenance, or for re-completion (drilling into new reservoirs from an existing well). Low-frequency motions for semi-submersibles and ships should be calculated in the horizontal directions only, that is, surge, sway and yaw. [6], On July 29, 2009, Shell and Samsung announced an agreement to build up to 10 LNG FPSOs,[7] at same Samsung Yard Flex LNG appeared to construct smaller units. From potential projects to projects under contract as well as any changes to FPS units deployed world wide is tracked in this comprehensive report. Industry Guidance Notes or Recommended Practices are non-binding recommendations, which are sometimes incorporated into design criteria either in whole or in part. [12], At the opposite (discharge and regasification) end of the LNG chain, the first ever conversion of an LNG carrier, Golar LNG owned Moss type LNG carrier into an LNG floating storage and regasification unit was carried out in 2007 by Keppel shipyard in Singapore. The selection of a technically feasible and cost-effective mooring system type is primarily dependent on water depth and environment. The FSO, owned and operated by MODEC, is under a service agreement with PEMEX Exploration and Production. The calculation takes into account the contribution of both the current and the FPS offset, which are the major components in the evaluation of the max. The frequency or time-domain methods may be used to establish the vessel low-frequency response about this stable equilibrium position. Floating Production Systems The Aalborg Industries Group is a leading supplier of equipment and services for Float-ing Production Systems such as FPSOs, FSOs, FSUs, FSRUs, etc. As of this writing, production Spars have only been installed in the Gulf of Mexico. 6.1 Oil and Gas Production. The layout of the subsea architecture must also be considered within the context of mooring system analysis. The normal ship ICCP systems are all potentially controlled, that is, they sense protective levels on the hull and ramp the system output up or down to maintain the level within a preset range. Catenary systems tend to be costlier at larger water depths (say, more than 1000 m), as the mooring lines become very long. These systems must be cathodically protected, but system designers must be aware of the potential for hydrogen gas accumulation, elevated temperatures, or significant pH changes in static tanks. The spread mooring is a natural extension of the traditional mooring of ships. Mooring line analysis must include the influence of line dynamics, if the vessel is to be used for floating production or storage, or if operations in depths greater than 200 m are considered. Subsea wells are expensive, but not as expensive in deepwater as placing a platform at the site. A marine growth density of 1325 kg/m3 is common, and the standards provide equations to calculate the mass of growth depending on the line type and diameter, together with growth thickness and water depth. [23] BP also selected Aker Solutions to perform the detail engineering, procurement and construction management assistance (EPcma) for the Skarv field development. For long-term mooring systems, where onshore inspection is not possible, only limited connection elements, such as D shackles or triplates (fig. TLPs have been installed in the Gulf of Mexico, West Africa, the North Sea and in Indonesia. 2.3) and 4×4. It is important to establish a stable equilibrium position for the vessel, where the steady forces of current, wind and wave drift balance the restoring forces from the station-keeping system. Floating production storage and offloading vessels are offshore production facilities that house both processing equipment and storage for produced hydrocarbons. [17] A contract for an FPSO to operate in even deeper waters (2,900 m) for Shell's Stones field in the US Gulf of Mexico was awarded to SBM Offshore in July 2013. All materials supplied by TPK .

The HR and flexible jumper are in operation are filled with exported gas. Therefore although the spread mooring system is cost-effective, its application to large ship-shaped floating structures is only suitable for areas of a benign environment or where the directionality of wind, wave, and current is persistent, such as in offshore West Africa. Catenary system with an all-chain setup (best for very shallow waters). A LNG floating storage and regasification unit receives liquefied natural gas (LNG) from offloading LNG carriers, and the onboard regasification system provides natural gas exported to shore through risers and pipelines. FPSO Dalia Customer Total Classification: B.V. 3 TPK Deck mounted Boilers 35 MW Complete re-tubing of evaporation elements Complete renewal of back wall Gas outlet boxes, insulation and cladding 100% x ray. Guidance notes and standards give examples of contour lines. Floating production systems are flexible, cost and schedule effective solutions in particular for deep water applications. The chain fatigue data presented in API RP2SK is for the stud link chain. Huacan Fang, Menglan Duan, in Offshore Operation Facilities, 2014, Adapting floating production systems for deeper waters in bad sea conditions. Only a brief overview is given here. Yong Bai, Qiang Bai, in Subsea Pipelines and Risers, 2005. Ensuring that the mooring system has suitable reserve capacity when one mooring line or one thruster has failed – accidental limit state (ALS). The line drag coefficient can be assumed to increase linearly with growth thickness. The model testing has been addressed in detail in Chapter 13. Global strength analysis requires mapping of the hydrodynamic, the gravitational and the inertial forces onto a structural model consisting of plate, shell, beam and/or truss elements. Subsea wells may also result in lower reservoir recovery simply because of the physics of their operation. “Response-based modelling” is not presently required by any rules or recommended practice, but it may be specified by the owner. Floating Production Systems Around 280 floating production systems of various types are in service worldwide and another 65+ are on order. The hull is delivered in January 2010. The specific requirements for design of mooring systems are defined in Classification Rules and Industry Recommended Practices by API RP 2SK, Det Norske Veritas and Bureau Veritas. Floating production systems suitable for large oil and gas field and condensate oilfields. Where mobile offshore units change location frequently, other connections such as Kenter shackles, C links and swivels are allowed in the mooring line make-up. The safety factors are also applied differently. As shown in Chapter 3, diffraction effects may be neglected if: In practical terms this means that diffraction (and radiation) may be ignored for member diameters less than about 40 ft. Characteristic line tensions for ULS, ALS and FLS can be found using the storm stiffness. [25] Largest User of them is Petrobrás as of January 2015. Floating Production System (FPS) market is split by Type and by Application. These include thruster tunnels, sea chests, and annular spaces inside turrets. Most of the Mobile Offshore Drilling Units and some floating production systems use the spread mooring system for station-keeping purposes. The DNV curves are shown in fig. Fatigue curve parameters for wire rope and chain. For mooring chains designed to be positioned at the same location for greater than four years, the characteristic capacity of the line must be reduced for the effects of corrosion. The safety factor applies to the mean and dynamic tension components, that is the last two terms on the left hand-side of equation (8.10). Over the decades, ABS classed the first floating production, storage and offloading (FPSO) vessel in US waters, classed the industry’s first semisubmersible production unit, verified the first tension-leg platform (TLP) in the Gulf of Mexico, and classed the first production spar. Lee, et al (1999) describe the ABS approach on synthetic ropes, while Stoner, et al (1999) present the contents of an engineer's design guide for fibre moorings, emphasising the limitations in the available test data. This is why many systems fail in service and have to be replaced. Additionally, if the stress process has negligible low-frequency content, then narrow-banded assumptions allow the damage to be established in terms of the stress standard deviation. In other words, the HR and flexible jumper are considered to be filled with seawater (hydrotesting or accidentally flooded). Representation of a crude oil–natural gas separation system. Updated daily – 24/7/365 – courtesy of World Energy Reports’ global network of correspondents and analysts – the database is a powerful tool that enables you to research, discover and produce the information you need, when you need it, in the form you want to see it. An FPSO is a floating production system that receives fluids (crude oil, water and a host of other things) from a subsea reservoir through risers, which then separate fluids into crude oil, natural gas, water and impurities within the topsides production facilities onboard. The FPS can be used in water depths from 600 to 6,000 ft. Long-term floating production vessels use spiral strand steel wire ropes as this has improved fatigue and corrosion behaviour. The FPSO is moored at a depth of 2,600 m in Block 249 Walker Ridge in the US Gulf of Mexico and is rated for 80,000 bbl/d (13,000 m3/d). This section of the standards gives methods and guidance associated with the design of thruster-assisted moorings. This may be done in the frequency or time domain. These are referred to as equally-spread mooring systems. FPSOs can be a conversion of an oil tanker or can be a vessel built specially for the application. Catenary and taut leg mooring systems. This depends on sea and current conditions, mooring and riser make-up, together with water depth. Design of Floating Production Systems April 23 - 27, 2018. Fatigue properties of wire and chain are typically defined in terms of T–N relationship derived from tension–tension fatigue tests. The necessary structural arrangement for the mooring equipment is also specified, together with arrangements and devices for towing purposes and measurement of line tension. According to industry sources (Westwood), the floating production systems will be growing at a rate of almost 30 per year through 2006, mostly in deepwater. This usually corresponds to the wave and wind conditions having return periods of 100-yr, together with 10-yr return period current conditions. Standards specify the relevant load bearing yarn properties and tests to be documented, together with those for the yarn sheathing material.
