Basic Design
BASIC CONCEPT
The FPSO comprises a new build turret moored monohull vessel capable of continuous
operation in the CNS. A minimum service life of twenty years is required and it is envisaged
that the FPSO will be demobilised after ten years service for major survey, maintenance and
repair. The FPSO exports oil to the existing Shell/Esso fleet of shuttle tankers or to third party
tankers. Tankers are moored astern to the FPSO during loading.
The FPSO is connected to subsea production manifolds using flexible risers, flowlines and
control umbilicals. All FPSO systems, including the subsea systems, are monitored and
controlled from a single control room by an integrated Control and Management System.
The main functions of the FPSO are summarized as follow: production of dead crude for
export by shuttle tanker; export of associated gases consistent with the Fulmar Gas Line
requirements; treatment of produced water prior to disposal overboard; provision of facilities
for water injection; provision of facilities for water injection; provision of utility systems for
FPSO shipboard, topsides and subsea operations; space and weight provision for a future
identical gas compression train, production separator, oil import and gas lift are included.
BARGE DESIGN
The barge is designed to receive, store and offload crude oil produced from subsea wells and
treated in the topside facilities. Minimum provisions to allow future import of stabilized crude
are provided. It is capable of storing 850,000 bbls of crude, based on 98% of full capacity
excluding the slop tanks. It is provided with a helicopter deck, accommodation space (which
functions as the TSR -- Temporary Safe Refuge) and a machinery space, all located at the stern
of the barge.
The barge has a double hull consisting of side ballas tanks over the full length of the cargo
tanks, and a single bottom. The main hull is divided by bulkheads into the following
compartments: fore peak water ballast; no. 1 side water ballast tank; cargo tanks and side water
ballast tank; cofferdam; machinery room and double bottom space; aft peak water ballast tank.
The cargo tank part is divided by transverse bulkheads into seven cargo oil tanks, and one pair
of slop tanks. A centre line swash type bulkhead is provided in the cargo oil tanks. The centre
tanks are allocated to crude oil storage, while the wing tanks are used for seawater ballast
exclusively.
The produced oil from the topsides is received with a decanting line to where final crude
dehydration takes place. In this process the remaining water settles by gravity prior to being
displaced to one of the slop tanks for further treatment to allow overboard disposal.
Dehydrated crude oil is then transferred to the dedicated oil storage tanks.
All tanks are designed for filling levels ranging from empty to full in terms of local tank
strength. During normal operation ballast tanks can be either full or empty to allow ease of
operation. The barge is operated on an even keel condition in combination with ballast
operation with a slight trim by the stern during stripping operations.
The cargo tanks are equipped with individual submerged cargo offloading pumps. Crude oil is
exported via a fiscal metering system to a tandem moored shuttle tanker. The cargo piping
system is designed to enable simultaneous reception of crude oil from the topside facilities and
offloading of the cargo. The cargo and slop tanks are equipped to allow crude oil washing,
inerting, venting and gas freeing of any individual tank without affecting the safety or the
continuity of crude oil production and storage. All cargo and ballast tank equipment and
associated systems are remotely controlled and monitored from the ICC (Installation Control
Centre) located within the TSR.

Mooring
The turret benefits from the experience SBM Inc. have gained from their latest turret designs,
and limits the number of critical mechanical components, such as the bearings, by using a
single roller bearing located at the optimum vertical position for weathervaning.
It consists of a chaintable structure anchored to seabed anchor piles via twelve catenary
mooring anchor lines, able to limit excursions to 24 metres in extreme conditions. The anchor
system consists of, from top to seabed: 110m chain attached to base of turret; clump weight
consisting of 150m x 6" double length chain; 30m x 6" chain; 700m x 5.5" Bridon sheathed
spiral strand wire rope; 150m x 6" chain attached to 2.1m diameter x 31m long pile.
The chaintable structure is suspended from a heavy duty roller bearing which is located
approximately 7 metres above the keel of the FPSO. The 7m diameter triple race bearing,
fabricated by RKS, is supported on the tanker side by a reinforced box structure integrated into
the forward part of the FPSO vessel's hull. A turret cylinder, housed in a 12.6m diameter well
and extending upwards until some two metres above the vessel's main deck, is mounted to the
earth-fixed side of the main bearing. The turret cylinder houses the riser 'I-tubes' and supports
the turret main deck, the manifold platform, and the swivel deck together with the swivel stack,
the mooring line and riser winches, and all the earth-fixed part of the rigid piping. A radial
bearing assembly is used at tanker main deck level to absorb the radial loads caused by the
accelerations of the upper turret structural mass and to act as a radial bearing during a possible
offshore change-out of the main bearing. The entire assembly including manifold platform and
swivel extends some 30 metres above the main deck.
When the vessel moves off station, due to the effects of wind, wave and current, certain anchor
lines are lifted. This generates a restoring force which returns the system to the equilibrium
position, thus limiting the vessel's excursion.
The turret mooring system is designed to securely moor the FPSO tanker in all sea states up to
and including the survival sea state while allowing transfer of fluid products to and from the
barge.
Fluid transfer is achieved by flexible risers which are routed through the turret mooring and
interface, with rigid piping at manifold deck level. The product is then passed through toroidal
swivels to the barge main deck and the process facilities. The swivel stack comprises, from
bottom to top: space for future swivel (2 x 8"); space for oil production swivel (2 x 8"); oil
production swivel for Teal South/Guillemot A (2 x 8"); oil production swivel for Teal (2 x 8");
water injection swivel (1 x 8"); hydraulic/chemicals/vent swivel (multiple path);
electrical/signal swivels (multiple path/dual units); gas export swivel (4" pipe swivel). The
turret's manifold area is protected from possible wave action (green water) by a raised bulwark
extension of the barge's bow.
A tubular steel overhead framework is positioned directly over the turret to provide access in
order to perform maintenance and operational functions. A 40 tonnes pedestal crane,
supported by the FPSO vessel deck, serves the complete above deck turret to remove swivels
and perform other maintenance functions.
A hydraulic power unit, located on the FPSO deck, provides power via the swivel to activate
the several types of valves in the product lines.
The turret can accommodate up to 14 risers of various
Riser System
diameters; initially 6 risers and 2 umbilicals were installed.
The flexible risers are supplied by Wellstream.

Basic Design
The Berge Hugin is the first of a series of multipurpose shuttle tankers (MST) prepared for
FPSO operation. The ship features a load-bearing deck to accommodate rapid installation of
production topsides; the facilities are contained in standardized modules which can easily be
transferred to another similar ship if required. Topside facilities of up to 3500 mt in 100-200
mt packages can be accommodated on the aft part of the deck. The MST has a double-skinned
hull and incorporates the submerged turret loading and production system developed by
Statoil, APL and Framo.
As an alternative to FPSO use, the ship can be employed as a shuttle tanker. In this mode it
can stern load while moored to a buoy, storage unit or production system, or it can load on DP
without anchoring. Alternatively, it can load via an STL (submerged turret loading) buoy as
developed by Statoil and partners and employed on several fields. It can also be used as an
FSO with no further modifications.
The 'Berge Hugin' was initially taken to Blohm + Voss in Hamburg for about six weeks
preparatory work, then to Aker McNulty on Tyneside for outfitting of process topsides.
Topsides consisting of eleven modules, weight about 5000
Main Components
tonnes; four of the modules were fabricated by Aker McNulty,
which installed all eleven; other modules were supplied by
Proser, Baker Hughes Process Systems, Enerflex, KCC
Process Equipment and IKM.
Mooring
The MST uses a DP system for positioning; mooring/loading in a production situation uses the
APS developed STL/STP system. The main component in submerged turret loading (STL) is a
buoy which floats below sea level and is pulled into the bottom of a shuttle tanker before
loading begins. Deployable in a range of water depths, the buoy incorporates a turret shaft and
riser swivel that allow the tanker to weathervane through 360° and remain bow-on to wind and
waves at all times. First adopted by Shell in 1993, STL is currently installed on 11 vessels.
Submerged turret production (STP) involves a special disconnectable swivel that permits STL
ships to be converted easily for oil output. Multipurpose shuttle tankers use this solution in
production mode. The swivel can transfer a multiphase wellstream containing oil, water and
gas via a flexible riser into the weathervaning vessel. STP is suitable for developments based
on subsea production, and can be adapted for small or medium-sized fields, such as satellite
reservoirs. On small fields, several risers from seabed wells can be tied to the swivel via the
submerged buoy. It is also deployable in deep water. In the case of the Berge Hugin the ship is
moored using suction anchors.

Basic Design
The Petrojarl 1 is a purpose built turret moored production ship, equipped for operating
flexible or rigid production risers. A crude stabilisation plant is located aft of the turret, with
crude stored onboard for offloading to a shuttle tanker. The ship is equipped with a workover
derrick for wireline/coiled tubing work, and can be upgraded to heavy workover duty. A
number of modifications have been made to the original newbuilding: in October and
November 1991 the ship was upgraded by HMV to allow for operations from two wells, as
well as improved NGL recovery and increased water handling. Between the Hudson and
Blenheim contracts in the winter of 1994-5 it underwent modifications at Lloyd Werft in
Bremerhaven. These included: installation of a new process control system; replacement of
the gas lift compressor with a larger unit; turret altered to accommodate up to eight risers and
umbilicals; installation of a Brown Brothers multipath swivel; new riser connections; crude oil
coolers; hydrocyclones for produced water treatment; and replacement of 8 x 600m mooring
chains with studless type anchors.
Main Components
Mooring
Turret mooring with eight anchor legs, each consisting of a mooring winch, mooring line and

uses a roller bearing system for vertical support of the turret and for centralizing the turret in
the turret well; the bearing system is activated and controlled hydraulically; new multipath
swivel system fabricated by Brown Brothers and installed 1995
Can produce through rigid or flexible risers; normally flexible
Riser System
risers in 'wave' configuration are used; risers run from the wells
to the turret, through a moonpool in the turret and into a
common manifold where an emergency release coupling is
employed on each riser; 1995 upgraded to take 8 risers and
umbilicals; fitted with three Wellstream 6-inch production and
2-inch gas lift risers for the Blenheim contract; additional riser
for Bladon was added early 1997.

Basic Design
The Banff FPSO (also referred to as the 'Ramform B380') is based on a wedge-shaped
'Ramform' hull design. The vessel is double hull. The turret is located forward of midships,
allowing the ship to 'wavevane', or turn with the waves. The exceptional stability reduces the
requirement for ballasting, thereby increasing the allowable deck load. The Ramform design
has been described as the only vessel design that can take its entire deadweight on deck,
thereby allowing a great deal of flexibility in configuring the process facilities. It is said to
require only half the building time and one-third the amount of steel as comparable
conventional FPSOs.
The Ramform Banff FPSO vessel suffered major difficulties in the year 2000, being subject to
violent motion in the seaway attributed to deficiencies in the novel hull design. This produced
excessive roll, outside design specifications. The consequence was a number of system
failures and difficulties for personnel. The vessel has undergone significant design changes.

Basic Design
The tanker was a double hulled design being built by Samsung for Tanker Pacific of
Singapore, when the contract was taken over by Kvaerner Oil & Gas Ltd (KOGL) for use as an
FPSO for Amerada Hess. The original design was upgraded by Amerada/KOGL and the ship
was sent to Sembawang under its own propulsion to undergo the modifications programme.
This included primarily: additional steel work to give added strength and service life,
installation of topsides support stools, stern discharge grillage, cooling water caissons, fire
pumps, HVAC system and major deck cable trays and cabling work. The turret casing, with
top and bottom bearing housings 6m diameter and 25m apart, was also installed. The FPSO
was then moved to the KOGL yard on Teesside for installation of the turret and completion of
the topsides.

Basic Design
The FPSO was converted from a conventional motor tanker 'Dirch Maersk' purchased from AP
Moeller; main modifications included: turret mooring; multiple production, gas, water
injection and gas lift risers plus control umbilicals; flare; dual fuel power generation and
processing equipment located in large modules, located on the main deck supports; stern
offloading system; control and monitoring system; helideck; and upgraded safety features.
Main Components
Mooring
The Bluewater designed 4.5m diameter internal turret is located close to the bow and consists
of the following main components: nine anchor piles to anchor the nine individual mooring
legs to the seabed; nine composite (100m Ramnas 5.25" chain/1100m Bridon 5.25" spiral
strand cable/420m Ramnas 5.25" chain to surface) mooring legs grouped in 3 x 3 mooring legs
equally spaced at 120 apart; an internal turret with spider to connect the nine mooring legs by
means of automatic chain stoppers (the turret also carries the hawse pipes through which the
risers can be pulled in); a bearing arrangement which connects the turret including the 200 mt
spider with the vessel hull, enabling the tanker to weathervane 360° ; riser pipes which conduct
well fluids, injection water, gas and umbilicals through the turret to a platform above the main
bearing; a swivel stack for the passage of product, test product, gas water and air, at pressures
to 5000 psi; the swivel has four flow paths for well bore fluids, max. diameter 10 inches, max.
operating pressure 4200 psi; and a slip ring for powering the electrical systems in the turret.
Contracts include: structural castings, River Don; swivel castings, Weir; anchors & chains
supplied under subcontract to Rockwater; mooring wire/chain installed by Smit Maritime
('Taklift 8')/Ugland ('Maxita').
Originally nine risers in turret: 4 x production, 4 x gas lift, 1 x
