The BIMCO Liquid Cargo database is intended for use by for shore-side staff and to some extent for newcomers to the tanker trade and should only be used as a reference tool providing brief information regarding the more than 360 of the commonly transported liquid cargoes including Condensate.
Trade name/synonym name:
Condensate is a MARPOL Annex I cargo. Product name may be indicated in shipping documents as "Crude oil", "Naphtha's and condensates" or other relevant name depending on origin, according to MARPOL Annex I Appendix I.
Sour condensate; Sweet condensate; Field condensate; Lease condensate; Gas drips; Casinghead gasoline; Natural gas condensate, C2-C8; Retrogate condensate; Natural gasoline; Petroleum crude oil condensate.
Main Properties:
Extremely flammable liquid and vapour. May contain or release poisonous hydrogen sulphide gas.
Clear to straw, or dark brown coloured liquid. Pungent hydrocarbon odour.
The natural gas condensate is also called condensate, or gas condensate, or sometimes natural gasoline because it contains hydrocarbons within the gasoline boiling range. Natural-gas condensate is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. Condensate consists mainly of light liquid hydrocarbons such as pentanes and heavier hydrocarbons recovered at associated and non-associated natural gas wells. Condensate will normally enter the crude oil stream after production, but it can also be shipped as a separate commodity.
Some gas species within the raw natural gas will condense to a liquid state if the temperature is reduced to below the hydrocarbon dew point temperature at a set pressure. Therefore, the condensate is separated from the natural gas before the natural gas is further handled.
Main chemical and physical properties:
Flash point: Down to minus 50 deg. C, depending on grade
Boiling Points: Points is typical in the range 20 - 200 deg. C (Initial boiling point may be below 0 deg. C depending on grade)
Viscosity: @ 20°C < 50 mPa.s
Vapour pressure: @ 20°C > 5 kPa
Density: Typical in the range 500 - 750 kg/m3 @ 20 deg. C.
IBC carriage requirements:

Relevant additional IBC req.: N/A.
MARPOL Requirements: Annex I - Pollution Category: N/A
Special information to be added to Shipping Document: Standard information. MARPOL Annex I cargo.
Stowage:
Heat adjacent: Ambient
Stow adjacent to fuel oil tanks: Yes.
Carriage requirements:
Heating during voyage: No. Avoid heat adjacent
Heating during unloading: No
Tanks inerted or padded: Yes, according to SOLAS Chapter II-2 Reg. 5.5, requirements for oil tankers.
Prewash required?
No prewash required.
Tank cleaning:
Follow tank cleaning safety instructions for petroleum from ISGOTT chapter 11.3 (for inert tanks or for non-inert tanks respectively)
Ambient temperature water wash, followed by Hot/warm temperature water wash
Depending on next cargo: Recirculate suitable tank cleaning additive. Follow manufacturer's recommendations regarding temperature and concentration
Fresh water rinse.
Important:
Always transfer tank cleaning water from Annex I cargo to slop tank for settling. Do not pump directly over board. Do not mix tank cleaning water from Annex I cargo with tank cleaning water from Annex II cargo.
Use Oil Record Book Part II for loading-, unloading- and tank cleaning records.
Emergency Response:
Fire: Use foam or water spray - not water jet
Spillage: Eliminate sources of ignition. Collect small spills with absorbent material. Larger spills: Try to collect and transfer to spill tank or wash away with water. When in port, - inform Port Authority
First aid: Remove victim to fresh air. Follow first aid instructions in MSDS. Consider obtaining advice from Radio Medical.
Hazards (Occupational safety etc):
Toxic. Causes skin irritation
May contain hydrogen sulphide H2S and benzene. May cause cancer.
Precautions:
Obtain full cargo specification prior to acceptance as the grades of condensate vary widely
There are many condensate sources, and each has its own unique gas condensate composition. In general, gas condensate has a density ranging from 500 to 800 kg/m3, and is composed of hydrocarbons such as propane, butane, pentane, hexane, etc.
Remarks:
Use: The main use of condensate is as Refinery feedstock. Condensate is also often used to dilute highly viscous heavier oils that cannot otherwise be efficiently transported via pipelines.
The BIMCO Liquid Cargo Database contains information for more than 360 cargoes, all updated to the IBC Code 2021 amended requirements, but in order to ensure that the BIMCO Liquid Cargo Database information is kept updated, we highly welcome any feedback in the form of comments, response, information or data regarding a specific cargo.
