據油氣新聞3月23日消息稱，從4月開始，全球石油供應將出現有史以來單季度最大的供應過剩，造成每日約1000萬桶的供應失衡。雷斯塔能源的獨家分析顯示，全球存儲基礎設施陷入困境，在短短幾個月內將無法接收更多的原油和產品。

我們目前的流動性平衡顯示，到2020年，平均每日供應將超過石油需求近600萬桶，導致今年累計隱含庫存增加20億桶。

根據我們的嚴格分析，我們發現目前世界上大約有72億桶原油和產品儲存，其中包括目前在海上油輪上的13億到14億桶。我們估計，平均而言，全球76%的石油儲藏量已經飽和。

油輪上基本上沒有閑置的儲油能力，因為沙特阿拉伯和其他產油國可能已經在2020年3月和4月消耗了超大型油輪(VLCC)的可用儲量。

我們的數據顯示，目前在岸原油和成品油的理論可儲存能力僅為17億桶。根據我們對2020年平均每日600萬桶隱含石油庫存的預估，理論上講，需要9個月的時間才能填滿所有岸上儲油罐。

浮動存儲通常使用VLCC，它們可以儲存約200萬桶石油。我們估計，目前全球大約有802艘可用的VLCC，總載重量為2.5億噸，總儲油能力為18億桶。整個全球艦隊，包括較小的Suezmax和Aframax船，估計總容量為6.3億噸或46億桶。

但是，為了保持區域之間的石油流動，必須有大約50％的壓載物，因為油輪經常需要空載抵達目的地，在目的地，它們需要裝載貨物，這意味著，在任何時候，世界上約有一半的油輪被預訂前往消費目的地，而另一半空油輪在去取油的途中。這使得可用船只的數量減少到57艘左右。

根據目的地的不同，在現貨市場租一輛VLCC的成本已從上月的每日約2萬美元升至20萬至30萬美元之間。

Rodriguez-Masiu總結道：“我們發現，與當前的生產計劃相比，液體供應將必須減少約300萬至400萬桶/日，以使隱含庫存量在2020年接近200萬至300萬桶/日，這是我們認為在中短期內可持續的隱含庫存水平。”

History’s Largest Oil Glut Months Away From Topping World Storage While Tanker Freight Rates Explode

The largest oil supply surplus the world has ever seen in a single quarter is about to hit the global market from April, creating an imbalance of around 10 million barrels per day (bpd). An exclusive Rystad Energy analysis shows global storage infrastructure is in trouble and will be unable to take more crude and products in just a few months.

Our current liquid balances show supply surpassing oil demand by an average of nearly 6 million bpd in 2020, resulting in an accumulated implied storage build of 2.0 billion barrels this year.

Based on our rigorous analysis, we find that the world currently has around 7.2 billion barrels crude and products in storage, including 1.3 billion to 1.4 billion barrels currently onboard oil tankers at sea. We estimate that, on average, 76% of the world's oil storage capacity is already full.

There is essentially no idle storage capacity available on tankers, as Saudi Arabia and other producers might have already wiped out the available population of Very Large Crude Carriers (VLCC) for March and April 2020.

Our data shows that the theoretical available storage capacity at present is just 1.7 billion barrels onshore for crude and products combined. Using our estimate of an average of 6.0 million bpd of implied oil stock builds for 2020, in theory, it would take nine months to fill all onshore tanks.

Floating storage normally uses VLCCs, which can carry about 2.0 million barrels. We estimate that there are about 802 VLCCs active globally with a combined capacity of 250 million deadweight tonnage (dwt), capable of collectively storing 1.8 billion barrels. The entire global fleet, including smaller Suezmax and Aframax vessels, is estimated to have a combined capacity of 630 million dwt or 4.6 billion barrels.

However, to keep oil flowing between regions, a ballast of around 50% is necessary as cargos often need to travel with no cargo to the destinations where they pick up oil, meaning that at any given time around half of the world’s fleet is booked traveling to consumer destinations, while the other half is empty on their way to pick up oil. This reduces the number of available vessels to about 57.

The cost of renting a VLCC on the spot market has risen from about $20,000 per day last month to between $200,000 and $300,000, depending on destination.

“We find that liquid supply will have to be reduced by around 3.0 million to 4.0 million bpd compared to the current production planning to bring the implied stocks builds closer to 2.0 million to 3.0 million bpd for 2020, which is the level of implied stocks build that we find sustainable in the short to medium term,“ Rodriguez-Masiu concludes.
