Project Introduction:

Jeonnam 1 is a 96-MW offshore wind farm located off the coast of Shinan County, Jeonnam Province in the southwest of Korea. Comprised of ten wind turbine generators (WTGs), Jeonnam 1 represents the country’s first commercial offshore wind farm.

The water depth at the site ranges from 5 to 20 metres, with monopile foundations featuring monopiles with diameters of up to 8.5m. The wind farm is scheduled to be operational in 2025.

ESCO was appointed as the marine warranty surveyor (MWS) for the transportation and installation (T&I) for the foundations, export cable, inter array cable and wind turbine generator components. The scope of work included providing expert technical reviews, document approvals, vessel inspections and site attendances.

Having successfully completed the installation of the foundations and export/inter array cables, the installation of the first WTG was completed on September 30th 2024. Surveyors from ESCO Korea and ESCO Singapore attended on site to oversee the successful operation.

Results

• A secure operation was accomplished through the combined support of ESCO’s Korea and Singapore offices providing engineering support to the project.
• Streamlined operation and minimised delays on the project schedule with on-site technical review.
• Upon the successful completion of the first WTG installation, ESCO’s experience and lessons learned on site where communicated to secure all operations for the duration of the project.
• Installation operations of the last WTG components were completed December 2024

“It’s a great honor for ESCO Korea to successfully support the first WTG installation for the JOWP project. We are proud of our involvement in this significant milestone, being the marine warranty surveyor in the first privately held offshore wind development project in Korea.‘’

Project overview

Our thorough understanding and experience in delivering this type of project as an improvement cycle allowed a rigorous analysis and a robust improvement road map. The road map highlighted the improvement plan, steps for implementation and control.

Assessors and Verifiers will now be equipped with validation/evidence based on a recognisable process that is derived from the analysis and implementation plan covering the four focus areas of:

• ship management;
• maritime assurance;
• terminal management;
• and marine logistics.

This approach addressed any skills dilution that existed.

Challenges faced by the client

The client was experiencing challenges with skills dilution and current job competence profiles not at optimum.

Competency profiles were not aligned to Standards of Training, Certification and Watchkeeping  (STCW), International Harbour Masters Association (IHMA), Safety of Life at Sea (SOLAS), The International Convention for Prevention of Pollution from Ships (MARPOL) and the Oil Companies International Marine Forum (OCIMF) requirements.

What we did

Our scope of work was based on a three-phased approach:

Phase 1

Verify – Propose the controls that should be in place to support the improvement plan.

Define – Programme definition and descriptive problem statement.

Measure – Identify international/national or best practice standards and qualifications across the four focus areas.

Analyse – Carry out a comprehensive gap analysis and generate a report. 

Design – Develop an improvement plan along with suggested controls ready for the next phase of the programme.

Phase 2

Phase 2 was designed to provide implementation, assessment and verification of resources, as a follow on from Phase 1.

Job Competency Profiles covering approximately 40 positions across the four main shipping and marine areas were created.

Verify – Issue report to client for approval.

Define – Expand program definition and refine descriptive problem statement.

Measure – Confirm applicability of international/national or best practice standards and qualifications across the four focus areas. Provide assessment of assessor and verifier profiles.

Analyse – Carry out a gap analysis and generate report for all positions.

Design – Develop an improvement plan along with suggested controls ready for the next phase of the program.

Phase 3

The objective of Phase 3 was to hand over the entire process to the client.

Control – Ensure the designed implementation is being controlled through qualified and/or approved assessors and verifiers.

Implement – Apply designed improvements.

The value we delivered to the client

“The partnership between ESCO’s Asset Integrity Management (AIM) and Maritime teams has led to the successful development of an innovative approach that holds significant potential for global implementation.

By combining our expertise and resources, we have created a model that not only addresses current industry challenges but is also designed to be adaptable and scalable across various international markets.”

ESCO Head of Ports & Harbours Governance

“This collaborative effort showcases a strategic and effective solution that can be widely replicated, offering the potential to drive progress and set new standards on a global level.

We take great pride in the significant achievements and impactful results we have delivered for our client. Our commitment to excellence and dedication to meeting their needs have driven us to consistently provide outstanding solutions.”

Project overview

ESCO’s Asset Integrity Management team were contracted to prepare an equipment criticality review process document to be referenced in assessing the criticality of equipment at the client’s bulk storage asset (on site). ESCO also provided all changes to the asset register and criticality scores as an upload file for the client CMMS.

The project was based on existing asset standards and other applicable local/international standards as well as ESCO’s industry experience. It is expected that the criticality outputs will influence and guide the client’s maintenance function.

A fundamental part of the asset’s operations is effective management of the plant’s technical integrity. To assure this, it is imperative that all safety critical equipment and assets are identified, and the operational, maintenance and inspection routines are defined with the appropriate performance standard tasks.

Equally, to maintain the business obligations to customers at all times, it is important to identify all business critical assets, and put in place effective maintenance that will assure sustained reliability.

Challenges faced by the client

• The client had previously obtained an equipment criticality analysis from a local source however the outcome and findings were not detailed enough to understand how the classification had been decided.
• There was no audit trail or reasoning provided from the outsourced equipment criticality analysis to the client which created a vague decision process and low confidence.
• The client had a risk matrix that required updates with regards to likelihood and severity parameters.
• The corporate risk matrix procedures parameters required improved alignment with the parameters in the client’s 5×5 risk matrix table.

What we did

1. ESCO reviewed the scope of the client’s corporate guide document and found it was limited to the definition of the process for assessing equipment criticality within the asset.
2. Through an iterative process, we explored the best reference parameters for the risk matrix and implemented the improvements to the client’s guide document.
3. The risk matrix improvement is now contained within the client’s guide document and will provide a basis for future equipment criticality as their prescribed 5 year review cycle indicates.
4. The process in the guide considers the aspects of Safety, Environmental, Economic and Business impact in determining equipment criticality. The scope also includes the definition of:
   • Safety Critical Equipment (SCE)
   • Safety Critical Asset (SCA)
   • Business Critical Asset (BCA)
   • Provided equipment criticality for all maintainable equipment and reviewed at site with the asset team.

As the project developed, ESCO was contracted to conduct further work scopes that evolved in order to enhance the client’s existing Asset Register.

• Missing equipment was a specific scope added to capture more recently installed equipment and add to the existing Asset Register.
• Data cleansing of the existing Asset Register to provide more accurate data and consolidate the equipment class types.

Ports and harbours consulting to support feasible port infrastructure to support France’s floating offshore wind market.

Our Scope of Work

ESCO’s work was to define the wet storage solutions for 20 MW floating wind turbines inside and outside of the port. The work was divided into two phases.

Phase 1

Aimed to define solutions for each zone. The solutions were then compared through a SWOT matrix to define which ones should be examined in detail.

The solutions considered were:

• Dolphins inside the port. This solution ticked all the main boxes:
  • Limited space in the port
  • Can accommodate different FOWT designs
  • Low maintenance requirements
• Standard FOWT mooring outside the port. This solution allows the port to store a large amount of FOWT and can accommodate different FOWT designs

Phase 2

Assessed each solution in detail. This included:

• Solution detail design and layout
• Planning includes the engineering of the solution, the procurement and fabrication of different items, and the installation of wet storage. The planning also looks at the permits to be obtained before being able to start the construction
• Costing of the overall project to help the port to define the CAPEX
• A method statement defining how to use the wet storage areas
• Deliverables defining constraints in terms of permits (internal to the port and with French authorities)

The Conclusion

The work required a deep understanding of both port infrastructure and marine operations and expertise in floating offshore wind, from the components to transportation and installation (T&I) operations to future operations and maintenance (O&M) strategies.

With ESCO’s combined energy and marine expertise, we were able to provide a comprehensive service offering and evaluation of wet storage solutions for future FOWT at the port.
