Arctic OffshoreInnovation and Quality With a PurposeWe have developed products to meet the stringentrequirements of the offshore oil & gas industry formany years. The working conditions are tough andproducts have to be able to sustain extreme conditions.Our double latch hook, BKD, was developed with theaerospace industry as a role model; if one system failsanother one is ready to save the situation. The extra latchon the BKD will retain the load in case an unintendedopening of the first latch should occur.Our lifting systems have been valued for their longdurability and quality. Regardless of the environmentalconditions, our systems have provided lifting operationswith high safety. Our quality systems give us the tools towork with continuous improvements and we will alwaysput our great efforts into our mission to create thebest available in the market. Our quality is there with apurpose.DNV 2.7-1 certificateWe are type-approved by DNV to manufacture masterlinks and shackles in accordance with DNV 2.7.1specification. The approval verifies that GunneboIndustries has a high consistent level of productionstability in the entire process, from raw material to thefinished product.2

Arctic Offshore Master LinksType Approved to DNV 2.7-1Adverse weather and rough sea conditions - sometimes in combination with extremely low temperatures - must beincluded in the design and safety factor of container lifting sets. The heat treatment of the components must ensureproper ductility and strength to sustain shock loads which may be imposed when the container is lifted from the deckof a vessel.The lifting sets and its included components must be specially designed for the purpose to lift offshore containers.One of the main differences compared to the onshore standard or specification, is that it allows for the dynamicforces at sea by adding an extra enhancement factor to increase the level of safety. Another difference is that therequirements and testing of materials that will be used in cold environments, are more extensive.Arctic Offshore Master Link MT*Safety factor 4:12:24Arctic Offshore Master Link MAll dimensions in mm

Engineered to ExcellenceThe Master Links have been engineered to be resistant towards environmental hydrogen embrittlementfailures which are always a risk due to the corrosive environment present at sea. High quality steel that ishomogenous with favourable microstructure, small grain size and low amount of impurities is being used inorder to produce this high end component. In addition the hardness of the Master Links is below 38 on theRockwell C scale giving high impact strength even at low operating temperatures ( 27J at -40 C in the weld)and increased resistance towards hydrogen embrittlement failures in an offshore environment.100% Proof LoadingAll lifts require reliable products with the highest safety to ensure a safe working environment as well as toprotect the load. Gunnebo Industries perform rigorous testing in their factories before the product is released.100 % of the components of all batches are proof loaded 2.5 times their working load limit and visually inspectedby competent personnel. This is done without exception to guarantee highest quality and safety for the end user.To make the master links as suitable as possible for the harsh marine environment, an additional stress relievingheat treatment is performed before the master link is delivered to the end user. This is executed in order toremove any stress that might have formed during the proof loading, which might decrease the life length ofthe product.2Improved Working Load LimitsThe Arctic Offshore Master Links comes in an optimized range where each master link will have awider and higher working load limit span than the old range. This makes it easier from a purchasingpoint of view, as well as decreasing the risk of incorrect use. A table for the container ratings andrecommended master links can be found on page 2:26.Design Temperature -40 CThe Arctic Offshore Master Links are highly suitable to withstand shock loads and fatigue, evenin extremely cold conditions. The new master link range has a design temperature of -40 C,making it suitable for even the harshest weather conditions such as in the North Sea.Arctic Offshore Master Link MDNV 2.7-1 and DNV 2.7-3 Type Approved.Working Load LimitsArt. no.DNV 2.7-1CodetonnesMax.Containerrating* kgsEEN1677-4A-952/A952MASME B30.26SF 5:1tonnesSF 5:1tonnesLEDWeightkgsZ101486M-9T- OS9.34 5009.39.3270140253.0Z101487M-12T- OS12.57 50012.512.5270140283.8Z101488M-18T- OS18.513 50018.518.5270140325.1Z101489M-24T- OS24.021 00024.024.0270140366.5Z101490M-30T- OS30.525 00030.530.5270140408.2Z101491M-40T- OS40.0N/A40.040.03001804511.9Z101492M-50T- OS50.0N/A50.050.03002005015.3Z101493M-65T- OS65.0N/A65.065.03502005520.7Z101494M-90T- OS90.0N/A90.090.04502507042.7Z101495M-125T- OS125.0N/A125.0125.04502608057.5DL* For further information, see DNV 2.7-1DArctic Offshore Master Link MTDNV 2.7-1 and DNV 2.7-3 Type Approved.EWorking Load LimitsArt. no.CodeDNV 2.7-1tonnesMax.containerrating* kgsEN 1677-4A-952/A952MASME B30.26SF 5:1tonnesSF 5:1tonnesL1LEDledWeightkgsZ101586MT-9T- OS9.34 5009.39.34302701402516095226.0Z101587MT-12T- OS12.57 50012.512.54302701402816095257.8Z101588MT-18T- OS18.513 50018.518.5460270140321901102810.8Z101589MT-24T- OS24.021 00024.024.0540270140362701403216.7Z101590MT-30T- OS30.525 00030.530.5540270140402701403621.2Z101591MT-40T- 50T- 65T- OS65.0N/A65.065.0650350200553002005051.2* For further information, see DNV 2.7-1LL1ldeAll sublinks have a WLL of min. 75% of the top link.2:25All dimensions in mm

In the year 2000, DNV published first offshore standard (OS) DNV-OS-F101 for the design of the offshore pipeline systems with limit states or load and resis-tance factor design (LRFD). This offshore standard has been continuously updated based on various joint industry projects and many offshore installations (DNV, 2000, 2005, 2007, 2010).

Maryland Offshore Wind Energy Act of 2013 Created a "carve-out" for offshore wind within Maryland's Renewable Portfolio Standard (RPS) that is equal to 2.5 percent of all electricity sales within Maryland. Created a financial support mechanism for "Qualified Offshore Wind Projects" via Offshore Wind Renewable Energy Credits (ORECs).
