Ras Isa Terminal |
|
Operated by: SAFER Exploration &
Production Operating Company (SEPOC).
Position: Situated at 15.07 N, 42.36 E.
This terminal consists of a 409,000 DWT
Floating Storage and Offloading Vessel (FSO) "SAFER" which
is permanently moored 4.8 nautical miles offshore Ras Isa.
The terminal operates 24 hours throughout the year, weather
permitting.
This terminal is used for the export of
Marib Light crude from the oil wells in Mareb.
There are no bunker/fresh water or
provisioning facilities at this terminal due to its
location. |

3 x 16 inch ANSI |
|
Cargo hose handling derrick / crane (OCIMF) safe working
load: |
o 80 ÷ 160
kDWT = 15 tonnes
o 161 ÷ 307 kDWT = 20 tonnes |
|
|
Additionally, the following requirements
apply to export tankers calling at the Ras Isa Marine
Terminal: |
|
1. All cargo tanks must be inerted to
IMO / SOLAS regulations. |
2. Export tankers must be capable of
one of the following: |
-
Simultaneously loading cargo and
deballasting with double valve segregation between
cargo oil and ballast water throughout;
-
Operating as fully segregated
ballast tanker; or
-
Loading a cargo quantity prior to
deballasting equivalent to the quantity of ballast to
be discharged.
|
3. Export tankers must arrive with
clean ballast. |
4. Export tankers must agree to load
in a tandem mode, should weather / sea conditions so
require or if requested by
the Marine Terminal. If requested by the Marine
Terminal. |
5. Export tankers must be fitted with
OCIMF recommended bow chain stopper(s) of tongue type or
hinged bar type
(AKD) to accommodate size 76 mm chafing chain(s) as follows: |
NOTE: SMIT TYPE BRACKETS ARE NOT
ACCEPTABLE |
6. Mooring equipment required for
export tankers loading alongside the FSO SAFER are: |
All export tankers must have a
minimum of 16 mooring lines which include the minimum,
number of mandatory winch mounted mooring wires of given
breaking strength and mooring winch brake holding
capacity shown in the table below.
Note: Export tankers will be accepted
to load alongside with less than 16 mooring lines only
with favourable weather conditions and with the approval
of the Master of the FSO SAFER. |

7. The Marine Terminal Operator (SEPOC),
at its sole discretion, will not provide supplemental
mooring wires to the
export tanker. |
8. Export tankers must have closed
chocks. |
9. Export tankers must adhere to
OCIMF guidelines for the control of drugs and alcohol. |
10. In order to receive helicopters,
export tankers must have a helicopter landing area
adhering to OCIMF guidelines. |

Special parameters & Conditions: |
|
Year Round |
In addition to the dimensional
limitations and other technical requirements listed above,
the following parameters and conditions will govern
lifting’s of crude oil from the Marine Terminal:
-
Split parcel loadings will be allowed
consistent with available inventory, available entitlement
of the lifter, and confirmation of the lifting schedule as
established by the Marine Terminal Operator.
-
The Marine Terminal Operator will make
every effort to minimize loading time on each lifting.
When weather conditions and export tanker equipment
permit, alongside mooring will be utilized. However, at
the sole discretion of the Marine Terminal Operator,
tandem mooring will be utilized if it is deemed prudent to
do so.
-
Should deteriorating weather require a
berthing change for an export tanker already moored
alongside to the designated Holding Anchorage, or to the
tandem mooring mode, all related charges associated with
the re-berthing will be for the account of the lifter, and
time consumed shall not count as used lay time. Where, in
the sole opinion of the Marine Terminal Operator, it is
deemed prudent to do so, the Operator may, for
considerations of (among other things) adverse weather,
sea or meteorological conditions, fire, emergency, vessel
traffic or other peril of the sea, close the Marine
Terminal. Any such closing may be carried out with or
without notice and shall impose no liability upon the
Operator.
|
Special Lifting Conditions: |
In addition to the dimensional
limitations and other technical requirements listed above,
nominations for cargo lifting in excess of 1,200,000 BBLS
aboard the same vessel may be loaded in two parcels but will
be treated as completely separate liftings with two (2) sets
of lay days. In the event of a second parcel lifting on the
same vessel, the Marine Terminal will not be liable for
demurrage claims while waiting - between assigned lay days.
Additional charges for pilotage, mooring tugs, helicopter
service, etc., will be for lifter's account. |
