ExxonMobil Guyana Limited plans to establish a services agreement for the provision of one or more DP2 chemical carrier vessels or platform supply vessels to support operations in the Georgetown area.
The company issued a Request for Information to identify suppliers capable of delivering suitable vessels. Options include existing chemical carriers, newbuilds or converted vessels that meet ExxonMobil Guyana’s minimum operating requirements.
The vessels must be able to transit the Demerara River to a charterer-nominated shore base, with a maximum draft of 6.5 meters in fresh water. Dynamic positioning must meet DP2 standards with target follow capability and station keeping in line with IMCA 1580. Each vessel is required to have at least two bow thrusters and two stern thrusters.

Tanks, cargo pumps, and pipelines are required to be stainless steel for Ship Type 1 and Type 2 chemicals, with minimum tank sizes of 100 cubic meters. Coated tanks may be considered for certain Ship Type 2 or 3 chemicals if coatings are suitable for methanol and xylene.
