Neptune: A Space-Stabilized Offshore Access System

The Neptune space-stabilized access system innovatively transfers people or equipment from a ship to a fixed offshore structure such as a wind turbine or oil/gas production unit by sensing ship motion and adjusting parts of the system to keep the payload motionless. It consists of an articulated arm on a gimballed base mounted on an offshore support vessel, compensating for vessel movements to ensure safe and efficient transfers. The full-scale unit can carry four people or three with a stretcher evacuation, reaching a height of 28 meters above sea level with a vessel stand-off distance of 15 meters. The project is in its third stage, focusing on proving the concept with a satisfactory control system. The Neptune system targets the offshore oil/gas and wind-energy industries, offering a safer and more cost-effective alternative to helicopters and crew transfer boats, enabling year-round transfers in difficult weather conditions.

Feedback Overview:

The Neptune system presents a highly innovative solution for offshore personnel and equipment transfers, addressing significant safety and cost concerns. To increase its market potential, further focus should be placed on refining the control system and ensuring scalability. Additionally, marketing efforts should emphasize its year-round operational capability in harsh weather conditions, which is a major differentiator.
