Project

Geotechnical scope and site survey for construction use

  • Duration: 9 days. Scope: Shallow water vibro core testing in waters down to 6 m LAT  
  • Duration: 10 days. Scope: Geotechnical work and investigation for bridge structure
  • Duration: 6 days. Scope: Geotechnical work and investigation and seabed strength for jack-up vessels working at Vattenfall and Ørsted sites
  • Duration: 87 days. Scope: OWF- Vesterhav North / South for Vattenfall execution of both drill-core and CPT test. Geo's heave-compensated drilling rig designed for high-quality geotechnical sampling and testing, and GeoScope heaviest seabed CPT rig with a press capacity of 200kN
  • Duration: 24 days. Scope: OWF Kriegers Flak was an emergency call from client due to the fact that existing contractor on site was behind schedule and winter was closing in
Key lessons learned from project:
The skill set needed for two companies as NCTO and GEO, with different high levels of expertise on a joint task for world leading offshore windfarm construction companies, was instructive but overall the mutual goal was the same.

With NCTO the project was given a high vessel flexibility for fast and complex mobilization between jobs, which brought the project cost down to a minimum.

The vessel capability for conducting multiple jobs with same vessel and teams meeting the end client's timeframe was a massive achievement.  NCT Offshore managed to conduct 3 medium and 2 larger scopes from the 24-oct-2016 to the 7-nov-2017 (total project days: 136 days).

Project

Ultra Deep Sea ROV Work

Due to our experience, knowhow and innovative approach we have successfully operated a dual ROV system at depths greater than 5,000 metres - for more than 10,800 hours of operation.
  • Part 1 - 10th. July 2016 to the 20th. of Sep 2016
  • Part 2 - 16th. of Feb 2017 to the 10th. of June 2017
  • Part 3 - 15th. of Dec 2017 – ongoing today
Key lessons learned from project:
“Working two companies together at sea for + 30 months, the skillset, mindset, planning, operation and execution are all crucial factors, in order to succeed with a project of this caliber. Together we have managed to set goals, objectives and worked together on all levels to carry out and plan this extreme project.

One of the key lessons learned is:
- Rethinking of the HSEQ system managing the safety onboard: Safety Awareness Walks are implemented with high focus on routine work
- All crew onboard (from both companies) are doing a staff rotation, in order to get a deeper knowledge and broader skillset

This has resulted in more initiative and constructive feedback in our standard HSEQ-reporting, which in the end creates a better working environment along with a higher level of mutual focus on accomplishing the task."
