The Braefoot Bay tanker terminal is in line for a programme of maintenance and modernisation work as part of a £140 million investment by ExxonMobil at its Fife sites.
The Mossmorran operator said the project would focus on its jetty loading facilities at Marine Terminal, outside Aberdour.
The firm plans to carry out the works between March and September this year.
It will run alongside a multi-million maintenance programme at Fife Ethylene Plant, aimed at significantly reducing unplanned flaring and the impact of noise, light and vibration experienced by local people.
The measures should also reduce the duration and volume of flaring.
ExxonMobil said some of the 850 contractors brought in as part of the wider programme would be based at Braefoot Bay.
It has proposed building a temporary “construction village” close to the site for car parking, offices and changing rooms for the duration of the works.
An ExxonMobil spokesman said: “It is proposed that this temporary facility is located on our own land outside of the boundary fence in a leased and adjacent field approximately 100 yards to the north east of the boundary fence line.
“This area has been previously used to locate a temporary village of a similar size during an expansion project at Braefoot Brae in 2011.”
He said every effort would be made to ensure access to Braefoot Bay and the coastal path was not restricted and that any noise and light was carefully managed.
Fife Ethylene Plant has been closed since September following the failure of two of its three boilers.
Operations are due to begin soon under the supervision of environment watchdog Sepa, which will publish regular updates during the restart.
An investigation by Sepa into an episode of prolonged flaring at the plant in April is nearing completion and the outcome is expected to be published in the coming weeks.
Both ExxonMobil and Shell, which operates the NGL plant at Mossmorran, have been told by Sepa to address issues which cause disturbance to locals and noise reducing flare tips will be installed by Exxon this year and by Shell in 2021.
