The U.S. Coast Guard (USCG) has performed an evacuation via helicopter of a 33-year-old male worker from an
oil platform located approximately 23 miles southwest of Port Fourchon, Louisiana.

The incident occurred on Saturday, 11 June 2023, and the Coast Guard Sector New Orleans watchstanders
received a notification at around 4:19 a.m. that a crew member was experiencing chest pains aboard the S
Timbalier 52 platform.

Following the request, the watchstanders coordinated the launch of an Air Station New Orleans MH-60 Jayhawk
aircrew to assist.

After the aircrew arrived on the scene and hoisted the crew member, the worker was transferred to awaiting
emergency medical services personnel at University Medical Center in New Orleans. According to the Coast
Guard, the worker was last reported to be in stable condition.

The South Timbalier Complex, which has produced almost 200 MMBO and over 1 TCF of gas, is made up of ST
36, ST 37, and ST 52 fields, which were acquired from Chevron by Arena Offshore in 2016.

The U.S. Coast Guard's assistance was required multiple times in the oil and gas sector over the past few
months. One of the recent cases entailed the third medevac of a crew member from one of Allseas' vessels
located approximately 13 miles offshore Port Fourchon, Louisiana.

Prior to this, a 28-year-old male worker was medevaced from a BP-operated platform located approximately 130
miles south of Port Fourchon, Louisiana. Additionally, a 37-year-old male worker was medevaced from an
undisclosed oil platform about 40 miles south of Port Fourchon, Louisiana.
