The 49m-wide by 293m-long tankers, which will have a carrying capacity of 155,000DWT each, will be used in an offshore oil field off the east coast of Canada.
Widely used in the North Sea, the east of Canada and the sea of Brazil, the shuttle tankers are designed to transport crude oil extracted from marine oil fields to storage bases on the ground.
The dynamic positioning system allows the shuttle tankers to withstand waves, winds and currents.
Samsung plans to deliver the three oil tankers, priced at around $110m per unit, by February 2018.
Samsung Heavy Industries member said: "We have been able to maintain the largest share of the global shuttle tanker market thanks to our advanced technology and rich experience. Shuttle tankers are high-value products.
"We expect to actually win an additional order, as this contract includes one optional unit."
Samsung Heavy Industries has so far signed $2.9bn worth of orders for 11 oil tankers, ten container ships and two LNG carriers, among others.
