GLAD200 System (Global Lake Drilling to 200 meters depth) 

Dynamic Positioning System

In water depths greater than about 200 m, anchoring becomes less effective as a means of maintaining the position of a drilling vessel. In these deeper waters, Dynamic Positioning (DP) is required. DOSECC has acquired a portable DP system with funding from the National Science Foundation and the International Continental Scientific Drilling Program. This unit is intended to be able to convert vessels of opportunity into drilling platforms. The system consists of four thrusters powered by four dieselhydraulic power packs. The system is controlled by a Nautronix JSDP5000 (DP-1 class) system that uses either a GPS signal or a seabed beacon for position keeping. The specifications of this system are provided in the following table.

• Thrusters
  Four hydraulic thrusters yielding 8,000 lbf each
  Propeller: 39-inch, 4-blade Kaplan, manganese-bronze with Kort 19-A nozzle
  Mounting: Thruster on mini-skid, positioned and attached according to vessel structural
  members.
  Weight: 5,800 lbs. each
• Hydraulic Power Units
  Four Cat 3406 diesels delivering up to 360 BHP @ 1800 rpm (full load)
  Fuel Consumption: 17.5 US gallons per hour at full load
  Day Tank Capacity: 150 US gallons
  Dimensions: 11'-43/4" long X 5'-7" wide X 9'-31/8" high. Note: an additional 3' is minimum clearance required at both ends of HPU for air inflow and outflow, making effective length requirement of 17'-43/4".
  Weight: 11,300 lbs. Each
  Placement: Within 50' of thruster
  Four roofs for power units
  Four muffler / exhaust systems
  Connecting hose bundle: 6 hoses, overall diameter of 6" (Old, probably need replacement)
• Controller
  Nautronix JSDP5000 Dynamic Positioning System (DP-1 class)
  Consisting of: 2 underwater beacons and battery packs
  1 hydrophone and cable
  1 control console / computer

Active Heave Compensated Drilling System

DOSECC's AHC-800 is an active heave compensated (AHC) coring rig that is capable of retrieving continuous core to depths of 800 m (water + sediment) in shallow marine and deep lacustrine environments. The system is modular and designed to fit on a variety of drilling platforms. The AHC-800 is designed to compensate for up to 8 feet of heave with a period of 8 seconds.

The AHC-800 uses a set of proven sampling tools that include:

• Shelby "push" tube
• Hydraulic Piston core (HPC)
• Extended Shoe, non-rotating
• Extended Core Bit, rotating ("The Alien")
• Diamond Core Bit (mining)
• Non-Sampling Assembly

The tools core a hole 5.50 inches (139.7 mm) in diameter. Most are designed to collect core within a plastic liner with an inner diameter.

 

 

 

 

 

DOSECC MONTCO Offshore Drilling Platform

The DOSECC MONTCO unit includes a drilling rig mounted on a liftboat. This combination allows drilling to continue during almost any sea condition.
