Slide 17
Objective-Offshore & Energy Scandinavia AB It is important
to know the maintenances schedule for both engines in order to have
an idea of how many times we could require parts and labor. The
comparison for both schedules is only for one DG. Then, we should
multiply by at least three since the philosophy is to run three
DGs. Maintenance schedule for both DGs

Slide 20
The maintenance rotation for CATERPILLAR is higher even though
we consider a friendly environment. However, due to CATERPILLARs
lower power rating, their maintenance schedule rotation will be
higher (worse) since will be necessary to run more generators to
fulfill power demand, and thus, this means more cost.

Slide 22
Objective-Offshore & Energy Scandinavia AB Reason for
Variation Area suggested from Yard for temporary refuge is within
class requirement. In order to get a more functional temporary
refuge, it is suggested to enlarge that area since our rig will
host 600 persons. Enlarged area will incorporate facilities as
toilets, water/food and emergency hospital. Besides, the enlarged
area, will be suitable to refuge 600 persons. This change give the
rig a total different platform in discussion with potential clients
from the safety aspect, which could add a value in the
negotiation.

Foam System (H307-YCRO-OJV-VOP-003)
Slide 29
Objective-Offshore & Energy Scandinavia AB Details
According to the Specification, the helideck foam system should be
FMS type which uses monitor to protect helideck area. We see this
system have some disadvantages and we count them: Even though
people is trained to take a position as fire fighter for helidecks,
there is the inconvenient of fear of fire, and there is no training
for that. This might do that fire fighters run away from the
scenario. One more thing to be taken into account, is that due to
stress, orders to firefighters, during the monitors operation can
be misunderstood, and thus spraying when jet is needed or
viceverse. A possibility exist that firefighters can be harmed by
the fire or stress. The wind stream is not constant from one
direction. This can lead to not cover with the monitors an area
that could be needing put out the fire.
Slide 30
Objective-Offshore & Energy Scandinavia AB 30 Proposal
Pop-up system has the next advantages: The system is a compact
DIFFS with pop-up nozzles and skid designed to mix foam concentrate
in to fire water carrying foam tank and proportioner. The system
proportions an exact rate of foam concentrate directly to fire
water line close to the nozzles only using some of the energy in
the water. This is added value to the client. Involves less persons
into firefighting activity, reducing the probability of more
casualties. Monitors can be taken away and it is accepted by
Brazilian Navy Directorate of Ports and Coasts through its Maritime
Authority Standards for Approval of Helidecks Installed on Vessels
and Offshore Platforms NORMAM-27/DPC, CHAPTER 7. FIRE PREVENTION,
FIREFIGHTING AND RESCUE (34 of 94).

IV. GRE Piping (H307-YCRO-OJV-VOP-005)
Slide 33
Objective-Offshore & Energy Scandinavia AB GRE Introduction
This study is based on ABS MODU rules 2015 which is the applied for
our project CR600, thus; The technical source is ABS Rules for MODU
and the result of this study is to be applicable to systems for our
project.
Slide 34
Objective-Offshore & Energy Scandinavia AB GRE Description
According to ABS (MODU Rules 2015) plastic means both thermoplastic
and thermosetting plastic materials, with or without reinforcement,
such as polyvinyl chloride (PVC) and fiber reinforced plastics
(FRP). Plastic includes synthetic rubber and materials of similar
thermo/mechanical properties. These plastic pipes can be used for
systems listed in the table 2. In table 3 you will find the typical
standards recognized by ABS and applicable to all systems. There
are special requirements that are to be applied to piping,
depending on location and/or service, and this can be seen in table
4.
Slide 35
Objective-Offshore & Energy Scandinavia AB Systems which we
propose to change piping are: YCRO354-L-722-XB-001 P&ID-Main

GRE Technical features Weight difference
Slide 39
Objective-Offshore & Energy Scandinavia AB GRE Technical
features Resistance The main reason industries are turning to GRE
piping is its resistance to corrosion. Among the liquids this
piping is bearing, we find: potable water, sea water, chilled
water, and other several chemicals.
Slide 40
Objective-Offshore & Energy Scandinavia AB GRE Technical
features Handling Application: Water Distribution, Industrial,
Municipal & Infrastructure, Desalination & Power, Oil &
Gas, Petrochemical & Marine Application. Compared to steel
pipes, GRE pipes are easier to handle and operate. Especially when
we thing in fittings and jointing the piping system. Steel pipes
require for all fittings and joints to be welded, then, this is an
important resource consuming activity, and thus adding cost. Among
the activities we have cutting, surface preparation, grinding and
cleanliness. Steel pipes cannot be repaired, they need to be
replaced and immediately, even the leak or damage is minor.
Slide 41
Objective-Offshore & Energy Scandinavia AB Regarding GRE,
when damage is minor, normally can be repaired quickly and easily.
Seal-lock-joint is a connection with an O-ring and locking key; its
maximum pressure is 70 bar. This minimize the use of fittings. It
is necessary to apply a small lay of grease and connect. You can
see the difference: GRE Technical features Handling
Slide 42
Objective-Offshore & Energy Scandinavia AB GRE Conclusion
The first conclusion is that plastic pipes are accepted to be used
widely, not only offshore but onshore too. There are several case
studies about why several different industries have turned to GRE
pipes. Municipalities have invested to change their old piping to
GRE. The main reasons, apart of added value, are :
Slide 43
Objective-Offshore & Energy Scandinavia AB GRE Conclusion
GRE piping exhibits exceptional highly resistance to corrosive
materials. In addition, they are tough, flexible and light, as well
as cheaper in the long run in comparison with steel pipes.
Moreover, its easier handling compared to not only steel pipes
makes less resources to be necessary. These and other properties of
high quality engineered thermoplastic, make savings can be counted
since the initial investment, and afterward, maintenance costs are
substantially indisputable. All the above means added value.

No: H307-YCRO-OJV-VOP-006, Variation to deck Crane. OJV has
proposed to upgrade both deck cranes from 60MT each to 75MT and
150MT. This is based on the configuration of other platforms that
are new or will be delivered in the next few years. Also OJV has
the opinion that the current cranes are marginal for the intended
service under realistic offshore operation, Which consists of lifts
from other vessels and fixed platforms. Another onboard operation
is to remove the whole gangway in order to add or remove pedestal
extensions. This to adjust the gangway height to fit the vessel or
platform we will connect with. This requires a higher capacity
crane and without this crane we need to rent a offshore heavy lift
crane for this operation. Additional Cost.

between the current TSC 60MT crane and Liebherr 75MT and 150MT.
Lifting is either: Onboard Lift i.e. You lift from your own
platform and land the load on your own platform. Offboard Lift i.e.
You lift from or to another vessel or Fixed platform For both lifts
the waves will induce dynamic loads that will reduce the actual
lifting capacity. The sea state is described with the Significant
Wave Height, Hs. Hs=1.5m is a normal sea state for offshore
lifting, but is can be carried out in worse weather with further
reduction of the lifting capacity. For the TSC crane Onboard Lift
is defined for Hs 1.5 and 2.5m and Offboard Lift for Hs 1.5 and
2.5m. For the Liebherr Cranes Onboard Lift at Hs 2.0m and Offboard
Lift at Hs 1.5, 2.0, 2.5 and 3.0m
Slide 48
Objective-Offshore & Energy Scandinavia AB 48 From the
tables below the capacities can be compared. The Hs are not the
same for the two makes but it gives clear indications. If we focus
on the Offboard Lift at Hs 1.5m we can see the summary below. (The
full Excel sheet is attached as a separate document.) Main hook:
The TSC crane at 18m radius has a capacity of 33.5MT, Liebherr 75
has 60.0MT and the Liebherr 150 has 85.0MT but at a worse sea state
of Hs 2.0m At 38.6m the maximum radius of TSC its capacity is down
to 12.8MT. At 51.0m the max radius of Liebherr 75 its capacity is
down to 19MT. At 60.0m the max radius of Liebherr 150 its capacity
is down to 18.7MT, but in a worse sea state of Hs 2.0m. Auxiliary
hook: The TSC crane at 38.6m has 10.0MT capacity. The Liebherr 75
at 56.0m has 15.0MT capacity. The Liebherr 150 at 65.6m has 25.0MT
at Hs 1.0m, 22.6MT at Hs 2.5m and 16.5MT at Hs 3.0m
Objective-Offshore & Energy Scandinavia AB 50 Cost for the
Liebherr Cranes. Liebherr has indicated costs for the Liebherr 75
and Liebherr 150 and the freight to the yard at EURO
2.6+3.8+0.6=7.0 million. This is about 7.85 million USD. The
shipyard has quoted 7.833 million USD for the VOP No:
H307-YCRO-OJV-VOP-006.

Slide 52
Objective-Offshore & Energy Scandinavia AB MGPS Reasons for
change ANNEX I. I-ET-000. ANEXO I - GENERAL TECHNICAL DESCRIPTION,
section 3.1 This section describes that The Unit shall have an
ionized chlorine shall be injected at the inlet of the seawater
lift system, to avoid fouling or marine growth. Chlorine is a
well-known toxicant. It has been shown that 0.2 to 0.5 PPM of
continuous chlorination will prevent all marine fouling in time.
Higher than 0.5 PPM might produce the corrosion of the metallic
piping, and other equipments.
Slide 53
Objective-Offshore & Energy Scandinavia AB MGPS Other
impacts Cooling piping. Chlorine is corrosive and will be necessary
to change pipes in shorter time. Water makers. Chlorine will reduce
the lifespan of membranes. This will lead us to install additional
filters in order to lower down the chlorine level. All above will
add costs during the rigs lifetime.
Slide 54
Objective-Offshore & Energy Scandinavia AB MGPS Assumptions
and notes According to some investigations, Petrobras does not have
any preference as soon as they are in compliance with international
standards. Beside this, some fiscals assure that ICAF is the
preferred. More man hours spent for maintenance as well as more
allocated maintenance, since this kind of method requires
continuous monitoring and control. Both are approved for using
according to IMO. Copper is the most effective product to prevent
barnacles and mussles from settling in cooling water inlets or box
coolers.
Slide 55
Objective-Offshore & Energy Scandinavia AB MGPS Comments
Now a days ships are equipped with MGPS. MGPS stands for Marine
Growth Prevention System. Its basic principle is based on the ICCP
system. Direct Current is applied to the anodes to emit ions in the
environment in order to change it into an unfavorable condition for
the growth of fouling organism. Normally Copper Anode and Aluminum
anodes are used. Changing to ICAF will benefit more parties since
will require not piping, less maintenance, no man hours
practically, less damages to equipments, and thus, less cost in the
long run save money.
Slide 56
Objective-Offshore & Energy Scandinavia AB MGPS Comments
ICAF is friendlier with environment. Benefits is, then, for all
parties. There is no final cost from shipyard for our proposal,
however, a refund is expected due to the lower cost of this
system.

Slide 61
Objective-Offshore & Energy Scandinavia AB 61 As known to
all, the advantage of WI-FI is to make people use portable
electronic devices freely, and is independent of fixed LAN
connection for an appointed place. On purpose to give more comfort
and convenience for client/crew live on platforms, we advise to use
WI-FI in cabins and public area of accommodation. This is a hotel
facility and the client are resting at our platform, we need to
make them satisfied on it. YCRO to evaluate the possibility to
install WI-FI on platform. And the reply from YCRO is no problem.
YCRO will summit TP and VOR.
Slide 62
Objective-Offshore & Energy Scandinavia AB 62 VIII. Mooring
(No final information from Yard)
Slide 63
Objective-Offshore & Energy Scandinavia AB 63 CR600 MOORING
SYSTEM The CR600 platform as proposed from CIMC Raffles has no
mooring system installed. The yard claims it is not required by ABS
for a DP3 unit. ABS can accept that you have no anchors provided
that the platform is assisted by tugs when in transit near/within
harbour, coast or busy waters. This is very expensive and in
addition Oil Companies will require that you can emergency anchor
in case you lose power when you are along side a production unit or
within an oilfield with numerous platforms. As an Owner you must be
aware of that many areas where there are oilfields have shallow
coasts and harbours are not very large. Most harbours will refuse a
platform to moor alongside a quay, you will block the harbour.
Therefore you anchor with 4 or 8 anchors in a bay or in a port area
if there are room enough.
Slide 64
Objective-Offshore & Energy Scandinavia AB All platforms
recently delivered or under construction have anchors. 8 point
mooring is most common, some has 10 point mooring for work in the
North Sea. There are a few units with 4 anchors to be able to store
the platforms between contracts. NAMEOWNERFLAGCLASSBEDSDECK

Slide 65
Objective-Offshore & Energy Scandinavia AB OJV has
requested a proposal based on an eight point mooring design. The
platform will be prepared for this. Thus there will at each corner
of the platform be an anchor rack that can store two anchors. The
columns will be reinforced and prepared for installation of two
fair leads. The deck will be prepared and strengthen for
installation of two winches with one power unit. We have asked for
a proposal to have the platform delivered with four sets of
winches, fairleads and anchors. The system can easily in the future
if needed be expanded to eight point mooring by adding the missing
equipment. The mooring system will be designed for a water depth of
200m using the installed mooring system. The intended use is to be
able to anchor and store the platform between contracts or during a
major maintenance job. With a complete 8 point mooring system you
can work alongside a platform on anchor with the option of POSMOOR
DP assisted mooring to further enhance the performance For deeper
water depths you can connect your anchor wires connect to prelaid
anchor system with chain. We are expecting a proposal from CIMC
Raffles in the near future.
