Dredging work to free the Ever Forward has begun, but specialists claim it may take up to a week to safely refloat the 11,850 TEU vessel.
“It is suggested that dredging may take up to a week to complete before attempts may be taken to safely refloat the vessel,” said WK Webster in a statement.
The firm also detailed that shipowners and salvors are aiming to lighten the ship to help solve the ongoing problem.
There have been no reports of any loss or damage to cargo, however, concerns over its impact on the environment are growing as there is talk of a potential oil spill.
Officials from the US Coast Guard are still yet to determine what caused the ship to get stuck.
The news comes on the one-year anniversary of when the Ever Given first began to obstruct the Suez Canal.
On 14 March, the Ever Forward ran aground in Chesapeake Bay near Baltimore.
Dredges from Don Jon Marine and Cashman began removing material around the vessel earlier this week.
