4.3 PROCESS DESCRIPTION
Facility of Pulau Sambu Fuel Terminal consists of receiving facilities from the
ship, storage tanks system, blending at the tank, and delivery to the ship. Fuel
product could be produced are HSD 0.35% sulfur, HSD 0.25% sulfur, MFO 180,
Bunker 380, and LSFO (Low Sulfur Fuel Oil).
HSD 0.35% sulfur is produced from blending HSD 0.2% sulfur and HSD 0.5%
sulfur. HSD 0.25% sulfur is produced from blending HSD 0.2% sulfur and HSD
0.05% sulfur or HSD 0.01% sulfur. MFO 180 is produced from blending MFO
180 Component, LSWR (Low Sulfur Waxy Residue), and DCO (Decant Oil).
Bunker 380 is produced from blending MFO 380 Component, VR (Vacuum
Residue) and HD (High density Oil). LSFO is resulted from blending VR, DCO,
and LCO (Light Cycle Oil).
Receiving of HSD 0.2% sulfur, HSD 0.5% sulfur, HSD 0.05% sulfur and HSD
0.01% sulfur are from Jetty 6 by LR ship and MR ship, including in Jetty 1 by
MR ship and GP ship. HSD 0.2% then filled to New tank T-40/41/42/43 and
existing tank T-8. Furthermore, HSD 0.5% delivered to New tank T-
40/41/42/43 to blend with HSD 0.2% sulfur producing HSD 0.35% sulfur. If

6. DESIGN BASIS
6.1. PRODUCT TRANSFER FACILITIES
There are total of Eleven (12) nos. of Product Pumps. Three (3) nos. of
centrifugal pumps for HSD and nine (9) nos. of positive displacement pumps
for non-HSD products, ranging from 500 m3/hr to 1500 m
3/hr, provided in
relation to 4 jetties with jetty pipelines connected to the jetties. This is to
realize optimal flexibility in tanker and barge loading, as this arrangement
allows both tanker and barge jetties to be served simultaneously. Some of
the pumps are equipped with variable speed drive. All pumps can be
switched to the specified tank line using valves which allows the following
operation:
1) Transfer of product from one tank to another tank;
2) Product re-circulation;
3) Receipt directly from ship to tank;
4) Delivery from tank to ship.
Flow Rates And Pumping Equipment
The following normal flow rates apply for the different products:

minimum flow requirements.
7.2.5. IMPOUNDING BASIN
The holdup for the impounding basin facility shall be at least 50% of
the volume of the largest tank draining to it.
7.3. LINE SIZING CRITERIA
Liquid velocities shall in general be kept low enough to prevent problems
with erosion, pressure surges, and vibration and reaction forces. In some cas-
es a minimum velocity (self cleaning velocity) is required to prevent water ac-
cumulation and bacterial growth. Liquid line sizing shall be in accordance
with API-RP14E.

The velocity on pump discharge should in between range 2.1 - 3.7 m/s (7 - 12
fps) at maximum flow rates, and velocity on pump suction should in between
range 0.91 – 1.5 m/s (3 - 5 fps) to minimize pressure drop and to meet NPSH
requirement.
Gravity lines includes drains (closed and open drains), and other lines where
the liquid flows due to gravity instead of pressure difference. Generally, a
minimum downward slope 1:500 or maximum liquid velocity of 0.76 m/s (2.5
fps) for straight flow.
Pipes that are running full, and do not require a minimum downward slope to
avoid particle deposition, shall be sized according to the total available static
pressure head, and the maximum allowable velocities for liquid lines.
