RP70 Self-elevating Mobile Platform
Amphibious Jack-up Platform, also called as Jack-up Rig, Jack-up Barge or Jack-up Work Platform, this is a very special and powerful marine engineering equipment, combining the features of a ship, a platform, and an amphibious vehicle. Its core features can be summarized as follows: it can float on the water, land on the bottom in shallow water or on mudflats, and use retractable legs to lift the platform out of the water to form a stable operating base.

Key Features & Functions

1.Amphibious walking
Core Function: This is where the name “jack-up” comes from. The platform is typically equipped with three or four (sometimes more) massive legs.
Operational Method: After reaching the target location, the legs are lowered or placed on the seabed via a hydraulic or electric gear system. The massive platform body is then lifted upward along the legs, completely out of the water.
Purpose: To create a completely stable working surface unaffected by waves, just like on land.
2.Adaptable to soft mud
Core Function: This is where the name “amphibious” comes from. The platform can float in deep waters as well as operate in extremely shallow waters, intertidal zones, and even flat mudflats.
Operational Method:
Floating Mode: During transfers or navigation, the legs are raised, allowing the platform to float on the water like a boat.
Bottom-Sit Mode: In shallow waters, the platform’s tracks can land directly on the solid seabed, providing a walking surface.
Jump-Up Mode: In deeper waters or on soft seabeds, the legs are used to raise the platform.
3.Low ground pressure
Features: A vast, open deck space with a strong carrying capacity. Its dimensions can be customized to meet personnel, equipment, and payload requirements.
Purpose: It can accommodate large amounts of materials and equipment (such as drilling rigs, diesel engine sets, and other exploration equipment), or serve as living quarters and work areas. It is essentially a mobile “offshore construction site” or “temporary island.”
