BUILT ICE CLASS A1
FOR HARSH CONDITIONS

The Dina Polaris is a 2017 build, DP2 vessel, specially designed for offshore installation services in harsh weather conditions. She is an ice class A1 vessel constructed according to Baltic rules allowing her to operate in cold climate environments in ice thickness up to 0.8m.

Certified Clean Design, she was designed and built to minimise her working footprint on the environment.

ON-BOARD SYSTEMS

Capable of handling 2500m of drill string. Ram hoist system with twin wire suspension giving safe, efficient and compensated handling of the drill string and all in-hole tooling.

A comprehensive range of wireline downhole sampling tools are available including piston sampling, push sampling, wireline core barrel and percussion (hammer) sampling. All downhole tools are fully compatible within the 5.5” API drill string. A range of drag and specialised coring bits are provided. Large diameter cores are possible thanks to the large diameter drill pipe.

Fitted with a wireline operated, 3m PCPT tool for cone penetration testing with pore water pressure measurement, and a wireline operated, 3m seismic PCPT tool for cone penetration testing with pore water pressure and seismic velocity measurements.  Presently 1200m PCPT umbilical and winch capacity which can be extended to 1600m. Downhole PS wave logger available as required.

ON-BOARD SOIL LABORATORY

The Dina Polaris is fitted with a Geoquip Marine soil laboratory, enabling our geotechnical engineers to immediately conduct soil classification and determine strength parameters for design, analysis and assessments in real time whilst offshore  The data allows our engineers to do spudcan penetration and/or pile capacity/installation analysis on-board as the borehole progresses, allowing an optimisation of the actual borehole depth.

Geoquip Marine Dina Polaris Offshore Laboratory

The laboratory is equipped with the necessary tools to conduct standard soil tests. Routine sample handling, photography, classification and storage are part of the everyday work process in the laboratory. The testing regime on samples varies and can be tailored to your project.

Recovered samples are stored in a temperature-controlled environment prior to shipment to an onshore facility.

SEABED SYSTEMS

As an option, the Dina Polaris can carry Geoquip Marine’s GMC201 20t seabed unit to rapidly conduct an array of in-situ tests.

Geoquip Marine GMC201 Seabed PCPT on crane

When your project requires lower seabed penetration depths, in either shallow or deep water, the seabed unit can be quickly deployed offering faster turnaround and cutting costs.

The seabed system is deployed through the vessel’s moonpool using the GMTR120 rig’s derrick and compensation system.
