12 Summary of possible types of damages The following types of damage are characteristic of laid-up or re-commissioned vessels: Example of hull related degradation: Corrosion of empty ballast tanks Corrosion of hull below water line Extensive corrosion of propeller Organic incrustation of hull below water line Swelling of timber decks in external areas and accommodation spaces Rotting inside accommodation spaces Corrosion of deck plates with standing water Corrosion of lower hull not protected by anodes in transit draft - in particular special areas Example of machinery and equipment degradation: Corrosion damage to liners, pistons, piston rings, gears and crankpins Corrosion of valve spindles in lines carrying seawater Leakage at brazed joints of pipelines Extensive corrosion of seawater lines Corrosion damage to the impellers, housing, seals and bearings of pumps Embrittlement of plastic pipes (drinking water and pneumatic control system) Heavy internal rusting of the gears of winches and deck cranes Example of electrical system degradation: Oxidation of generator circuit-breakers Inter-turn short-circuiting of solenoid coils Oxidation of relays Malfunctions of measurement transducers Starting up problems with malfunctioning regulators and control equipment. Electronic equipment start-up failures after months without power. 12

15 Class vs. Advisory 15

16 Classification Society General Owner should notify the Society when the vessel is laid up or otherwise taken out of service for a period of more than 3 months. A written notification by will be sufficient for the Society to change the status of the vessel to Laid Up. Surveys During lay-up, vessels shall be subjected to annual survey. The extent of the annual survey will be reduced compared to main class annual survey, but shall cover watertight integrity, bilge system, fire hazard and equipment in use. The following surveys apply for laid up vessels laid classed with the Society: Annual survey of laid-up vessel will be carried out at required intervals. Vessels manned during lay-up shall comply with class requirements regarding fire safety. The requirements may be limited to engine room areas and any high risk area in use, assuming vessels are laid up in ballast condition and that the cargo area is clean and gas free.. Maintenance and preservation during the lay-up period is not a class requirement, but will affect the scope of the re-commissioning survey. If during the lay-up period the vessel has been preserved and maintained according to a program accepted by the Society, the scope of the re-commissioning survey will be specially considered. There is no time limit for how long a vessel can be laid-up provided the required surveys as above are carried out. 17

17 Survey schedule during lay-up During lay-up the ship shall be subject to annual survey Lay-up Annual Layup survey Annual Layup survey 3. Annual survey 4. Annual survey Renewal survey

18 Scope of Annual Lay-up Survey Annual lay-up survey to be carried out at required intervals In addition: units which are manned should comply with class requirements for fire safety The requirement may be limited to engine room areas and any high risk area in use, assuming the ship is lay-up in ballast condition and that cargo area is clean and gas free. The scope of the survey will be reduced compared to the main class annual survey, but shall cover: Watertight integrity Bilge system Fire hazard and Equipment in use

19 Re-commissioning survey dependent on Vessel returns to normal operation Vessel sails on single voyage Vessel has/has not been maintained/ preserved during lay-up Time in lay-up Type and age of vessel Maintenance and preservation during lay-up period is not a class requirement, but will affect the scope of the re-commissioning survey. If during lay-up the unit has been preserved and maintained according to program reviewed by the society, the scope of re-commissioning survey will be specially considered.

20 Prolonged Survey Intervals Example 21

21 Prolonged Survey Intervals Preservation Declaration accepted by DNV GL class Documentation: Records of preservation upon completion Documentation: Maintenance plan for the lay up period Application to / Acceptance from flag Confirmation: Acceptance in Principle of Prolonged Survey Intervals. Pending on annual surveys and successful reactivation survey Annual Lay up survey: Same as for regular annual lay up survey Additionally focus on: Maintenance in general Maintenance of preservation Documentation: Review of maintenance records 22

22 Prolonged Survey Intervals Re-commissioning Re-commissioning survey Recommend early involvement from DNV GL /continuous contact Overdue surveys to be completed as for regular recommissioning Minimum scope as for an annual survey All elements of a renewal scope to be considered. Elements can be waived pending on condition and effectiveness of preservation Final scope to be agreed with DNV GL Upon successful completion of all surveys: Final acceptance from / information to flag New certificates with additional validity for time in lay up 23

23 ISM and ISPS Lay-up more than 6 months ISM and ISPS certification will be withdrawn. In the event the vessel is later brought back into service, an interim verification audit will be required, with the vessel being treated as a new vessel to the company. Upon successful completion of the verification, an interim ISM and ISPS certificates will be issued If the lay-up period is less than 6 months, but periodical audit window has expired during lay-up, the certificate will be considered invalid. The vessel will then be required to undergo interim verification upon re-commissioning. Lay-up less than 6 months For ISPS: If the vessel has been laid up less than 6 months and the periodical audit window has not expired the certificate will still be valid. For ISM: If the interruption period of the SMS on board the ship is more than 3 months but less than 6 months, then Flag State Administration may require an additional audit, in which case the Flag State Administration will issue the instructions. Upon satisfactory completion of the additional verification, the existing SMC shall be endorsed. 24

24 DNV GL Lay-up Services DNV s services on lay-up are available individually or in the combination best suited for the actual situation: General advisory service on lay-up scenarios Lay-up Declaration, Lay-up Clean Declaration and Lay-up Preservation Declaration as requested by the various parties involved such as insurance and port authorities. Development of lay-up Plan including specification and procedures. Risk Assessment to identify critical equipment Mooring Analysis, location approval and site evaluation Certification of lay-up service provider Review company s lay-up, preservation and recommissioning plan and process 25

25 DNV GL Lay-up services - Benefits The services provide a systematic and cost optimal preparation for lay-ups with focus on safety and cost efficiency. DNV GL's Declaration on Lay-up will meet insurance requirements. An App of lay-up declaration service will be deployed through My DNVGL. If the ship is preserved according to DNV GL's Layup Guideline, a Preservation Declaration will be issued and this will be reflected in a reduced recommissioning scope for DNV GL classed vessels. A well preserved ship during lay-up will ultimately result in reduced re-commissioning time and cost. 26

26 Clean lay-up declaration Munin - world first FPSO received DNVGL Clean Lay-up Declaration Mooring arrangement Safety and security of vessel lay-up Emergency Preparedness Procedures to prevent pollution Air and noise pollution Antifouling coating treatment and marine growth 27

27 Location Approval /mooring analysis and Lay-up declaration for inshore/quayside moorings for lay-up Mooring Analysis received Verification Issue PLA Survey Issue LA and Decl. Input data from client: Mooring analysis from independent marine consultancy Mooring equipment certificates (quay bollards, wires, ) Outcome from DNVGL: Preliminary Location Approval after satisfactory doc. review Mooring, Safety and Security survey on board Final location approval and lay-up declaration 28

28 Location Approval for jack-ups at inshore/quayside location If moored at quay, same requirements as for a floating unit If the rig is jacked up at a inshore or quayside location a Site Specific Assessment is required Global strength and foundations are considered, with main focus on the utilization of legs, leg-hull interaction, spudcan-soil interaction and foundation capabilities Applicable standards DNVGL-ST-N001 Marine Operations and marine warranty DNVGL-ST-N002 Site Specific assessment of mobile offshore units for marine warranty 29

29 What is a Declaration regarding shore bollard? An independent statement reassuring facility owners and and other stakeholders (authorities, insurance companies, Marine warranty surveyors, end users, etc.) that the facility is compliant with all relevant regulations and standards within the operational limitations stated in the declaration. 30
