VOC recovery from loading crude oil tankers

Value proposition

VOC recovery from loading crude oil tankers Volatile Organic Compounds (VOC) vapour from crude oil loading to tankers is a significant source for leaks of GHG gases to the atmosphere, a waste of valuable resources, and represents a major health and safety risk. A VOC recovery plant located on a Dynamic Positioning vessel adjacent to a loading crude oil tanker can collect these hydrocarbon gas volumes from the crude oil tanks, avoiding emissions to the atmosphere and converting this into significant revenues for the operation. The concept will save emissions corresponding to about 2 000 tons CO2 equivalents for each VLCC loaded. One (1) Vaholmen vessel can handle 80 - 100 VLCC loadings a year corresponding to emission savings of up to 200 000 tons CO2 equivalents / year.

The VOC recovery product (liquefied VOC - LVOC) has several commercial applications. One application is as fuel for vessels. There are already a number of vessels with engines that can run on LPG and LVOC giving cost & emission savings valuable charterers and ship owners. For the worldwide fleet of existing tankers (VLCCs, VLGCs) more than 3000 existing engines on long range vessels have the potential for modifications to apply LVOC fuel with potential for significant cost & emission savings. Other applications for the LVOC are e.g. as product for refineries, fuel for power plants and desalination plants, or re-injection into the crude oil.
