Frequently Asked Questions About Oil Storage

Asian Oil Storage is a Malaysian-founded energy storage and midstream infrastructure company. We own and operate four bulk liquid storage terminals in Singapore, Rotterdam, Houston and Fujairah, with 3.18 million m³ of combined capacity. We also develop new terminal infrastructure and provide infrastructure consulting, including planning, engineering and feasibility studies.

No. We are an independent storage and infrastructure company. We store products owned by our customers and do not take trading positions. That independence means our customers' commercial information and strategies stay confidential.

ASIAN OIL STORAGE SDN. BHD. is a private limited company incorporated in Malaysia on 24 January 2017. It is registered with Suruhanjaya Syarikat Malaysia (SSM) under registration number 201701003035 (formerly 1217185-M). Our headquarters is in Kuala Lumpur.

We have operations in five countries: Malaysia (headquarters), Singapore, the Netherlands, the United States and the United Arab Emirates. Our consulting and project work has also covered Indonesia, Vietnam, the Philippines and Brunei. Our customers are based in 18 countries.

Our four terminals have 3,180,000 m³ of nominal working capacity in 60 tanks: Singapore 820,000 m³, Rotterdam 760,000 m³, Houston 640,000 m³ (about 4.0 million barrels) and Fujairah 960,000 m³. A further 620,000 m³ of expansion projects is in development.

Our portfolio includes crude oil and condensate, gasoline and blending components, diesel and gasoil, jet fuel and kerosene, fuel oil, marine fuels (VLSFO and MGO), naphtha and petrochemical feedstocks, and biofuels (FAME and HVO). Availability differs by terminal. See the product table on our Global Network page. Acceptance of any product depends on terminal specifications, regulatory requirements, compatibility, safety assessment and contract conditions.

Our terminals are designed for crude oil, refined petroleum products, marine fuels, petrochemical feedstocks such as naphtha, and biofuels. We do not currently offer storage for liquefied gases such as LPG or LNG, or for speciality chemicals. For other liquid products, please contact us and we will assess compatibility with our infrastructure.

Our tanks range from 20,000 m³ to 120,000 m³. Smaller tanks, of 20,000 to 35,000 m³, suit blending components and smaller parcels. Our largest, the 120,000 m³ tanks in Fujairah, suit crude and large fuel oil positions.

Yes. We offer heated, insulated storage for fuel oils in Singapore (320,000 m³) and Fujairah (560,000 m³). The biofuel lines in Rotterdam are trace-heated to manage cold-flow properties.

Yes. We offer VLSFO and fuel oil blending in Singapore and Fujairah, gasoline blending in Singapore, Rotterdam and Houston, crude blending in Houston, and inline biofuel blending into diesel in Rotterdam. Blending services are agreed in each storage contract.

Minimums depend on the terminal and the product. As a general guide, dedicated tank contracts start at one tank, from 20,000 m³ upwards. In some cases, shared or commingled storage may be available for smaller volumes of standard-grade products. Please contact our commercial team with your requirements.

Yes. Most of our capacity is contracted on term agreements, usually from one to five years. Longer terms are available, particularly for customers committing to capacity in new expansions, where they can influence tank design and configuration.

When capacity is available, we offer short-term storage for periods from one month. Spot availability varies with market conditions. Our commercial team can tell you what is currently available.

Yes. Our multi-hub framework agreements let customers hold storage at two or more terminals under consistent terms, with one commercial team coordinating across locations.

Fees usually combine a fixed storage fee per cubic metre per month for reserved capacity with throughput fees for product movements above an agreed level. Ancillary services such as heating, blending, additive injection and extra tank cleaning are charged separately. Details are set out in each contract.

Customers can see inventory, movement history and documents through our online customer portal, which is updated after each movement. Monthly stock statements are provided as standard.

This depends on the terminal: up to 320,000 DWT (VLCC) in Fujairah, 120,000 DWT in Singapore, 110,000 DWT in Houston (draft-restricted by channel limits) and 90,000 DWT in Rotterdam (subject to draft). All terminals also handle barges or coastal tankers. In total, we operate 20 berths, 8 of them deep-sea.

Customers submit nominations through our terminal management system. Our scheduling teams allocate berth windows and keep customers informed of any changes. Vessels must pass our marine acceptance requirements before berthing.

Yes. The network has 48 km of transfer pipelines. Houston connects to regional crude and refined-products pipeline systems. Rotterdam connects to the port's pipeline corridor. Singapore has interconnections with neighbouring industrial facilities. Fujairah has dedicated lines to the port's oil-terminal jetties.

All four terminals have truck loading bays, 18 in total. Houston also has a 30-car rail spur for loading and unloading feedstocks and products.

Yes. We can take part as an adviser, a co-developer or a developer-operator. Our services cover site selection, feasibility, terminal planning, engineering, permitting support, construction management and operation.

Our consulting services include feasibility studies, concept development, proposal preparation and briefings, preliminary engineering (pre-FEED), and infrastructure assessment, including technical due diligence for acquirers and lenders. We have delivered 34 projects in nine countries.

The Borneo Oil Storage Terminal is a proposed deepwater storage and marine terminal in East Malaysia. Asian Oil Storage provides planning, proposal briefings and preliminary infrastructure consulting for the project. The planning-stage concept has a 480,000 m³ first phase and an 840,000 m³ masterplan. The project is currently in pre-FEED and EIA scoping, and remains subject to approvals and investment decisions.

As early as possible. The most important decisions, on site, capacity, marine configuration and phasing, are made at the start and fix most of a terminal's lifetime cost. Early involvement gives us the best chance to add value.

Through a group HSSE management system that sits on top of local regulatory requirements. It includes process safety management, independent overfill protection on every tank, a single permit-to-work system, emergency response teams at every terminal and regular drills (96 in 2025). Our 2025 Lost Time Injury Frequency was 0.38 per million hours. Full data are on our HSSE page.

All four terminals operate management systems certified to ISO 9001 (quality), ISO 14001 (environment) and ISO 45001 (occupational health and safety).

By 2030, we aim to reduce our Scope 1 and 2 emissions intensity by 35% against 2022 and to source 60% of our electricity from renewables. By 2025, we had reduced emissions intensity by 21% and reached 29% renewable electricity. Details are on our Sustainability page.

We prevent spills through several layers of protection: tank design with leak detection, independent overfill protection, bunded tank groups, impermeable loading areas, ship/shore safety procedures and trained response teams. We had no spills to water in 2025.
