Marine Geotechnical Drill 1750 – Near-Shore & Underwater Core Drilling Rig for Marine Engineering

Use Cases

The Marine Geotechnical Drill 1750 is engineered for civil, marine, and geotechnical contractors operating in challenging near-shore and underwater environments. It is ideal for:

• Seabed core sampling and geotechnical investigation
• Underwater tethered drilling from barges, pontoons, or platforms
• Near-shore foundation studies for jetties, bridges, pilings, and cofferdams
• Low-visibility marine drilling where simple, reliable controls are essential
• Deployment from service barges or custom seabed frames
• Long-duration marine projects requiring durable, modular equipment

If your work involves marine geotechnical drilling, this long-stroke system is purpose-built for those conditions.

Overview

A civil engineering firm specialising in near-shore structures needed a drilling system capable of:

• Collecting core samples below the seabed
• Operating underwater, tethered to a barge
• Functioning reliably in low-visibility and harsh marine environments

The Marine Geotechnical Drill 1750 was chosen due to its proven adaptability, lightweight modularity, and exceptional long-term reliability.

Its modular mast design allows quick mounting on:

• Barge decks
• Floating platforms
• Custom seabed subframes
• Temporary marine access structures

The rig has demonstrated outstanding durability — remaining fully operational more than 20 years after its first deployment, with only standard cleaning and maintenance.

Key Capabilities

• Purpose-built for marine and near-shore geotechnical drilling
• Lightweight modular mast ideal for barge or platform deployment
• Capable of underwater tethered operation
• Reliable in low-visibility marine conditions
• Adaptable to carriers, subframes, or bespoke marine structures
• Proven long-term resilience in corrosive environments

Technical Specifications

Drilling Capacity

• 75 m – N-size diamond coring

Power Supply
