OceanWorks International in Houston, Texas, has announced that it has designed, built, and delivered the first of five heave compensation units for an operator in the Gulf of Mexico.

The passive heave compensation system mitigates the vessel’s motion induced load on the tether management system during submerged operations in high sea states.

This first unit has a safe working load capacity of up to 21.5 tons.

The heave compensator pays out or pays in the umbilical cable without active controls in a range of ± 9ft.

For ease of transportation, it is design to fit in a 20ft open top container, and is fitted with four lift points (DNV lift certificate).

The unit’s flexibility allows for customized sheaves to cover various sizes of umbilical. The design allows for options including remote panel location, stainless steel tubing for better corrosion resistance, and customization for larger or smaller applications.
