The Harvey Energy OSV – which was the first of its kind in the region to run on both Liquefied Natural Gas (LNG) and diesel – will now become the first ABS-classed dual fuel and battery vessel and the first U.S. flagged OSV equipped with a battery/converter system. The Harvey Supporter will become the second vessel in the Harvey Gulf fleet to have a battery power system.

The battery installation, which is expected to achieve the ABS class notation ESS-LiBATTERY, will significantly enhance the efficiency and environmental performance of the vessel, ABS said.

According to ABS, the installation of a 1,450 kW battery hybrid solution is anticipated to reduce the Harvey Energy’s exhaust emissions, fuel consumption, and noise level.

The overall fuel cost savings are expected to be in the range of 10 to 20 percent, according to Harvey Gulf International.

The battery capacity will be sufficient to sail in and out of harbor on electric power with fewer engines running, while also supplementing hotel load electricity when docked, which would reduce noise and pollution levels in the harbor area. Furthermore, the ability to operate on battery power will assist redundancy during critical dynamic positioning (DP) operations at the offshore platforms, ABS said.

“ABS is a leader in hybrid projects in the offshore sector and we are proud to be involved in another project driving the sustainable development of the industry,” said Matt Tremblay, ABS Senior Vice President, Global Offshore. “The project will effectively create tri-fueled vessels with significant potential to reduce fuel consumption and emissions.”

To remind, ABS back had in March 2018 won a contract Seacor Marine’s Seacor Maya vessel as the first OSV in the Gulf of Mexico to operate using hybrid power. Seacor Marine completed the installation of the first hybrid power solution on an offshore support vessel in the Gulf of Mexico in June 2018.
