Joint Rig Committee

Marine Warranty Surveyors’ Code of Practice (COP)

 

The purpose of this COP is to:

 

a.    clarify the roles of the Marine Warranty Surveyor (MWS), assured and underwriters in the performance and specification of a Marine Warranty survey;

 

b.    establish agreed standards for the attending MWS when conducting a survey;

 

c.     define the lines of communication between underwriters and the MWS;

 

d.    establish agreed qualifications for the attending MWS when conducting a survey;

 

e.      where applicable, outline the basic requirements for the Certificate(s) of Approval (COA) and establish the definition of “first in series” as detailed in the JRC MWS COA Requirements section below.

 

Nothing in this COP shall relieve any party of any legal obligations existing in the absence of this document and nothing contained in this COP shall take precedence over any provisions of the Policy.

 

This Code of Practice has been produced to accompany the attached Joint Rig Committee Scope of Work (SOW). A tailored Project Specific Scope of Work (PSSOW) may be substituted with the explicit prior agreement of underwriter(s).

 

 

1.    The Role of the MWS

 

1.1          The fundamental objective of the MWS is to make reasonable endeavours to ensure that the risks associated with the warranted operations to which a Marine Warranty Surveyor is appointed are reduced to an acceptable level, in accordance with best industry practice.

 

1.2          The MWS Company will ensure that any individual MWS appointed to sign a COA in accordance with the SOW:

 

1.2.1      is appropriately accredited by the Society of Offshore Marine Warranty Surveyors (SOMWS); or

 

1.2.2      can demonstrate competence by completing document JRC MWS Information Form (JR2019-009) or the latest version that is available in the Technical Documents tab section of the JRC webpage (www.lmalloyds.com/jointrig) to the satisfaction of underwriters,

 

prior to commencing the activities.

 

1.3          The Marine Warranty Surveyor will issue a COA for each critical operation as defined in the relevant scope of work, provided that they are satisfied, so far as possible, that the operations are conducted in accordance with:

 

 

1.3.1      recognised codes of practice for design and operations;

 

1.3.2      best industry practice appropriate for the vessel(s), equipment and location(s);

 

1.3.3      vessel(s) and equipment being used within defined safe operating limits; and

 

1.3.4      the most current Marine Operations Manual available for the project; (Note: When an operation is conducted outside the Marine Operations Manual, this shall be subject to a formal Management of Change process, with senior leadership, technical authority and MWS approval.)

 

1.3.5      the MWS must be satisfied with work undertaken by other third party MWS (e.g. for any vessel).

 

1.4          Upon request the MWS shall propose an MWS plan to be agreed by the assured and underwriters which indicates, as a minimum, each activity, milestones, attendances and issuance of COA(s) for the project.

 

1.5           Upon request the MWS will make available to underwriters:

 

1.5.1      an opinion on the adequacy of the SOW – if there are any gaps or omissions this should be communicated to the Assured and the SOW updated accordingly;

 

1.5.2      a schedule of actual, proposed and repeat site attendances; and

 

1.5.3      a schedule of COAs to be issued.

 

 

1.5.4      COA requirements

 

The number of COAs required are as follows:

 

1.5.4.1    For WTG Foundation installation COAs shall be issued for 20% of all foundations of the same design and/or installation method. Different installation methods include drive vs drill/drive, different design includes a variance of more than 15 metres in the overall length of the foundation, or changes in the design of secondary steel work for different vessel embarkation approaches.

 

1.5.4.2    For WTG topside installation COAs shall be issued for 20% of all WTGs.

 

1.5.4.3    Every OSS foundation and topside installation shall have a separate COA issued.

 

1.5.4.4    For Inter Array Cable laying COAs shall be issued for 20% of all cables.

 

1.5.4.5    Every Export cable installation shall have a separate COA issued.

 

1.5.4.6    Every cable joint shall have a separate COA issued.

 

1.5.4.7    For Floating Offshore Wind, every unit will have a COA issued.

 

The above requirements are also applicable to decommissioning activities.

 

1.6           The MWS will:

 

1.6.1      advise underwriters when a confidentiality agreement with the assured is in place which would preclude the exchange of information or communication with underwriters; and

 

1.6.2      notify underwriters of any conflicts of interest. Examples of services that could present a conflict of interest with the Marine Warranty work, include:

 

1.6.2.1    Marine or Design Consultant (or equivalent) involved in:

 

a.    Design of project components to be used in a marine operation, the failure of which could compromise the integrity of a Project asset (for example a lift beam or padeye);

 

b. Primary analysis of structures, hulls or component parts thereof; (Note: The Marine Warranty Surveyor is, however, expected to review a design by others where this has a direct bearing on the marine risk e.g. check the lift analysis of turbine components.)

 

c. The production of procedures, project standards, risk assessments and other management documentation which influences how a marine operation is conducted and which any activity that has a direct bearing on the risk of a particular marine operation e.g. loadout, transportation, lift operations;

 

1.6.2.2    Loss Adjusting;

 

1.6.2.3    Verification services associated with the operation; and

 

1.6.2.4    Rig Moving (if required or used for a renewables project).

 

1.7          The MWS will immediately advise underwriters, with a copy to the assured:

 

1.7.1      if any COA is withheld, or a Non-Conformance Certificate issued. Reasons for this should be clearly stated.  Examples include:

 

1.7.1.1    failings of the documentation provided;

 

1.7.1.2    failings in the preparations made;

 

1.7.1.3    unacceptable change of circumstances which depart from the approved procedures and preparations at any point up to the planned issuing of a COA;

 

1.7.1.4    a proposed operation that is considered too dangerous to be considered as acceptable good practice from the outset or as preparations proceed, e.g. where weather conditions deteriorate to the point that they exceed the limits for a defined safe operation as agreed by the MWS;

 

1.7.2      if the assured fails to comply with any recommendations made by the MWS;

 

1.7.3      of any proposed changes to relevant key personnel employed by the MWS company.

 

1.8          The MWS shall inform underwriters of any:

 

1.8.1      access restrictions to a site or work place of any item or activity to be warrantied; and

 

1.8.2      continued lack of information for a warrantied event that cannot or will not be resolved on site but which may prevent the eventual approval of an operation;

 

1.9          The MWS shall agree suitable lead times for attendance at vessel / site and documentation release with the assured.

 

1.10       The MWS may use information available from verifiable sources to assist with the conduct of the Marine Warranty activities. Where such information is relied upon by the MWS it should be clearly referenced within the MWS Progress Report

 

 

2.      Role of the Assured

 

2.1.         The Assured must ensure that the selected MWS Company is suitably qualified to perform Marine Warranty activities in accordance with this COP and associated SOW (or PSSOW as applicable).

JRC Renewables Scope of Work (SOW)

 

The following summarises the Certificates of Approval (COA) required to be issued by the MWS at site prior to the commencement of each of the specified activities:

 

Offshore wind installations are usually categorised as follows:

 

·       Foundations

These can be piled jackets, monopiles, Gravity Based Structures (GBS), suction caissons or floating structures. All may, or may not, have transition pieces. Fixed structures can be installed from a jack-up or floating Heavy Lift Vessel (HLV).

 

·       Wind Turbine Generators (WTG)

These typically consist of tower sections, nacelles, hubs and blades and are typically installed using jack-ups.

 

·       Inter Array Cables

These can be supplied in a continuous length or cut to length, in addition to laying, the pull-ins are complex and the burial operations, together with any rock protection, comes with risks.

 

·       Export cables

Depending on the length these may require joints and will also require beach pull-ins, sometimes through HDDs and platform pull-ins followed by burial.

 

·       Offshore Sub-Stations (OSS)

These transformer platforms can be installed on a regular platform jacket together with associated topside installations. Sometimes the foundation can be a monopile or a GBS. The guidance for OSS is also applicable to High Voltage Direct Current (HVDC) converter platforms which may be separate installations.

 

For each of the above categories the following major marine activities (and issuing of COAs) takes place:

 

·       Loadouts.

·       Towage, transportation and offshore transfer (if required).

·       Installation of WTGs (fixed and floating), nacelles, rotor assembly (taken to mean blades and hub), jackets or monopiles (for Offshore Sub-Stations – OSS) and associated foundations, topsides for the Offshore Sub Station (OSS) platform, cable and subsea connections and foundations (including piling) for the WTG’s and jackets or monopiles for transformers.

·       Cable loading and offloading.

·       Cable ship/barge sailaway or other suitable marine transport.

·       Cable laying (covering trenching and burial).

·       Start-up, crossings and tie-ins.

·       Shore approach/pull-ins/Horizontal Directional Drilling (HDD).

 

These activities will also be similar and require a COA for other renewables projects (wave, current, tidal, solar, hybrid types)

 

The following table details all the required activities (reviews, independent checks and calculations, attendances etc.) and specific conditions that may apply associated with the above COAs.

 

Where this SOW does not adequately cover the operation(s) required the JRC Upstream Construction SOW (JR2019-006) should be referred to.

 

This document contains the SOW intended to be used with the JRC Renewables Marine Warranty Survey Endorsement (JR2020-030A).

 

 

 

Definition of Renewables:

 

Renewables are defined, for the purposes of this SOW, as being Marine Operations (loadout, transportation or installation) which are of a medium to high level of complexity including marine operations for offshore wind farms, involving structures, including fixed and floating foundations, transition pieces, towers, nacelles and rotor assemblies, inter array cables and export cables, OSS platforms and foundations, and HVDC converter platforms and foundations (if applicable).

 

The engineering and analysis required for Renewable marine operations would be significant and specific to the marine operation in question and require the use of specialist software and professionally qualified engineering personnel.

 

In addition to WTGs, this SOW will also apply to wave, current, tidal, hybrid types of renewables or other forms of renewable energy installations.

 

Scope of Work (SOW) 1:

General Activities applicable to all sections

JRC MWS Certificate of Approval (COA) Requirements

The Certificate of Approval (COA) is the final document in an approval process that includes numerous activities such as:

 

-  Survey attendances for suitability and/or condition of a vessel

-  Site assessment and vessel surveys

-  Document reviews and re-reviews

-  Site attendance to review preparations

 

As a result the COA is not a stand-alone document and the above activities must be referenced to ensure the whole process is completed to the attending surveyor’s satisfaction with its signing.

 

Basic Requirements

 

1.      A COA must only be issued if the surveyor signing the COA has witnessed the preparations for the operation and is in attendance at the site. It should be issued immediately prior to the commencement of the operation.

 

Exception: Location approvals of MOUs where the COA is issued by the approving office.

 

The COA should also be signed by the Assured’s person in authority on site (if present) to acknowledge receipt of the COA and acceptance of the recommendations.

 

2.      To assure validity of the COA, approval documentation from the office that performed the desk top reviews of the operation confirming the acceptability of the documents reviewed (plans, procedures, calculations etc.) shall be provided to the attending MWS.

 

3.      Each COA shall have a unique number.

 

4.      The title on the COA must be sufficient to identify the operation being approved.

 

5.      The MWS’s name shall be printed underneath the signature.

 

6.      The time at which the issuing of the COA has been approved shall be recorded and a period of validity (if issued for first in series and to cover a series of events) for the COA must also be recorded.

 

7.      The original COA shall be given or sent to the Assured with copies retained by the MWS company.

 

8.      Traceability of the COA is required by reference to the principal document(s) approved for the operation.

 

9.      Where appropriate vessel capacity (bollard pull, DWT., GRT., displacement etc.) is to be documented to help define a vessel’s suitability for an operation.

 

10.   For any COAs issued for the “first in series only”, or a percentage of components to be installed, this shall be clearly stated on the COA, together with conditions for its issue clearly stated.

 

11.   Checklists may be appended to the issued COA if required to clarify the scope of the approval.

 

12.   All recommendations related to the operation must be complied with prior to the issue of the COA and the COA must not be subject to any outstanding recommendations. However, any recommendations intended to be complied with after the issue of the COA, as mandated by the MWS, for example to cover an agreed activity after a tow departs or compliance with a procedures document, shall be specific, measurable, achievable, reasonable, time-bound and clearly listed, attached to and referenced in the COA .

 

13.   A UMR (Unique Market Reference) number is to be provided on all COAs. This number is available through the Lead Underwriter insurer and the Assured’s Broker.  A UMR is a unique number allocated to each individual policy. The UMR will enable clear traceability as to the Policy to which the COA pertains.

 

Notes:

 

1.    COA for the “first in series only”:

 

When approval for a repeated operation is required, for instance, to approve the installation of twenty monopiles, then the operations approved must be identical in all material respects to the first operation otherwise individual COAs are required for each operation. For instance, the foundation installation method, securing arrangements, vessel ballasting and trim condition, weather window and limiting weather criteria must all be the same. No additional cargo, change of securing practices, change of route, change of tug, barge or transportation vessel, or other alteration, compared to the initially approved condition, may be permitted without reference to the MWS. Where the change(s) are acceptable the MWS must endorse the original COA or issue a new COA. However, if multiple tugs, barges (or other vessels) or equipment have been approved for use in various combinations with MWS approval, then this is acceptable. If a loss or ‘near miss’ incident occurs during a repeat operation then the COA shall be suspended until the MWS is satisfied that the key root causes have been satisfactorily addressed. For operations involving greater value, loads, ‘at the edge of the envelope', and/or greater complexity then full attendance is required and issuance of COA shall be made in each case.

 

2.    Failure to Issue COA:

 

If the processes required for approval are incomplete, then the COA must not be issued. For example, if approved documentation from the MWS office performing the desk-top reviews has not been received or if recommendations issued by the MWS Office or attending MWS surveyor have not been completed or implemented.

 

3.    COAs which, after issuing, no longer conform to the operation originally approved:

 

If, after issuing the COA, the MWS surveyor notes any non-compliance with the basis on which the COA approval was provided or with any recommendation, intended to be completed after the issue of the COA, the attending MWS surveyor shall issue a document of non-compliance formally identifying how the terms, conditions and any recommendations of the COA have been contravened. In such circumstances, subject to confidentiality undertakings of the MWS company, the Lead Underwriter is to be informed of this and the surrounding circumstances at the first opportunity. In all cases the MWS company must ensure that the Assured’s representative is formally made aware of the situation (in writing).

1. All comments, recommendations or higher level requirements must be closed out before the CoA is issued. Hence one CoA is issued for each operation not intermediate stages otherwise it becomes meaningless.

2. TRN: Technical Review Note or similar depending on MWS company terminology. These are a list of comments on the documents being reviewed.
