Harbour

Oil fields extend up to 20 miles from the shore for a distance of over 60 miles E of Jakarta. Within this restricted area there are five (5) production platforms and many other oil structures interconnected by submerged pipelines for oil and gas.

Ardjuna Oil Terminal provides four berths for export tankers, one alongside a storage barge and three at SBMs, all moored in depths of about 40 m (132'). SBM 2, the SE-most, is designed for tankers up to 100,000 tdw.
SBM 4, the NW-most, is designed for tankers up to 200,000 tdw.


Each of the above mentioned SBMs is used for shipment of crude oil and is equipped with a dual 49 m (160') 15" circ. floating brailine mooring rope with anti-chafe chains of 6.7 m (22') in length. Crude oil is loaded through
two 242 m (795') long strings of 16" floating hoses, each ending in a 12" rail hose with 12" ASA 150 flange, which is connected to the tanker's port side manifold. All crude oil tankers not having 12" hose connection should provide their own reducers in such a way that they do not cause any delay in the hose connecting operation. The weight of each hose is apprx. 2.5 t.


Loading of crude oil from the storage barge to the tankers will be through A O Smith positive displacement meters, of which there are four, each having a max. capacity of 2,000 m3/h (12,500 bbls/h). Loading rates are of min. 2,400 m3 (15,000 bbls). Tankers loading at SBM 4 can accomplish a max. loading rate of apprx. 5,500 m3/h (35,000 bbls/h). Simultaneous loading from the two SBMs is not allowed. Masters are reminded that for safety reasons it is advisable to have the ship half loaded as quickly as possible.

Masters intending to follow the Load-on-Top procedure must inform the terminal in advance.

"ARDJUNA SAKTI", the LBG storage facility - is a pre-stressed concrete barge measuring 140 m by 41 m and having a depth of 17 m (461'*136'*56'). It is moored at SBM 5. The barge carries twelve tanks with a total storage
capacity of 60,000 m3. There are five (5) large Yokohama type rubber fenders, each of 6.5 m in length and 3.3 m in diameter on the starboard side of the barge.

LPG tankers are moored alongside the barge, using five (5) headlines, four (4) sternlines and four (4) springs. Vessels are requested to provide these ropes. Where tension winches are available, they will only be used if they can be
locked in a fixed position. The following Operating Rules have been adopted which shall apply to the lifting of products from the "Ardjuna Sakti".


1) It is the vessel's responsibility to provide a connection suitable to connect the Camlock flanges. Failure of the loading vessel to present the required 12" ANSI 150 flange for connection will result in rejection of the vessel for loading and cancellation of her Notice of Readiness. The terminal will have a limited number of spool pieces and reducers available but will not accept any obligation or liability to provide them.


2) Refrigerated LPG vessels will not be considered ready for loading at Ardjuna Marine Terminal unless and until all LPG tanks contain LPG vapours and are cooled down sufficiently to permit loading of products nominated.


3) Vessels receiving fully refrigerated products will only be acceptable for loading provided they are capable of receiving and keeping the products at a pressure up to 2.5 psi; such vessels must have a refrigeration system
capable of liquefying all vapours coming from vessels tanks resulting from loading at the max. rate of 3,120 m3/h and including these vapours are formed as a result of heat gained by the vessel's tanks.


4) The Ardjuna Sakti is equipped with a vapour compressor and condensing facilities for liquefying vapours, however, no liability of any kind whatsoever, to provide the compressor and or condensing facilities for vessel's use, is accepted.


5) Provided a vessel has the capabilities described in paragraph 3, at the sole discretion of the Terminal Superintendent or his designated representative, in the event the vessel has difficulties with her refrigeration system, the facilities available on the Ardjuna Sakti may be made available to assist the vessel provided they are operational. There is no obligation implied or accepted to continue to assist the vessel with chill down, even if assistance has been commenced. In the event that assistance is requested and is provided, all charges and expenses incurred must be paid for by the consignee. Such charges shall include any amount payable in demurrage for all the time that chill down operations cause the vessel to exceed the allowed laytime. The conditions set out in this paragraph (5 ) for assisting in chill down operations shall apply to purging operations.


6) Ardjuna Marine Terminal has no facilities for inerting arriving LPG tankers. It is imperative that arriving vessels do not arrive with tanks designated to receive product in air. Vessels arriving to load LPG will not be accepted for loading product, if the oxygen in the tanks exceeds 8.0 mole percent.


Loading
A pumping rate of 3,180 m3 (20,000 bbls or 1,600 metric tons/h) at a max. rail pressure of 10 psi can be achieved.


SBM 6, the NE-most berth, is designed to handle tankers up to 50,000 tdw and is used for shipment of Butane Plus. Tankers loading at this buoy will moor in the same manner as crude oil tankers. The weight of the cargo hose to be lifted is apprx. 700 kg (1,500 lbs). An arriving Butane Plus tanker will not be accepted for loading products if:


a) Oxygen in the tanks exceeds 8.0 mole percent.


b) Vessel is not adequately equipped with boil-off liquefaction unit capable of liquefying all vapours coming from vessel's tanks resulting from loading at the max. rate of 115 m3/h.


c) The bow to manifold distance exceeds 122 m (400').


There is no facility for inerting butane tankers on SBM 6, nor is there a ship's vapour return line facility. Masters of vessels are strongly reminded to ensure that ship's vapour compressors are in good running condition.
Failure to observe such requirement may result in cessation of the loading and any delay so caused will be on the ship's account.


Loading
Butane Plus is loaded through a 220 m (722') long string of 6" floating hose extending from the SBM and connected to the tanker's port side manifold. The hose is equipped with a 6" ANSI 150 quick-release Camlock flange. Tankers not having a 6" manifold connection must provide their own reducer. Failure to fulfil this obligation may result in rejection of the vessel for loading and nullification of her Notice of Readiness. Venting of products while the vessel is within the terminal is not allowed. The quantity of Butane Plus delivered will be determined by a metering system consisting of two (2) 3" A O Smith positive displacement meters.


Cargo Documentation
When a tanker has been loaded, the documents shall be completed and be taken on board the tanker for the Master's signature. This will take place at the same time as final departure clearance formalities are being carried out. Notes of Protest, if any, should be handed to the mooring master, who will acknowledge receipt of the Note of Protest only. The mooring master is not authorized to accept such letters.
