4 Product Range Through many years of experience and technology strictly orientated towards customer requirements, a range of products has been created which sets new standards in innovation, quality and reliability. The BOS crane is a rope luffing type offshore crane with open A-frame design. The crane is available in various sizes and different lifting capacities ranging from 25 t up to 1200 t. The boom length is adjustable and can be extended up to 102 m for some models. The BOS cranes are suitable for any kind of offshore installation, either floating or bottom supported, as they provide all appropriate safety and safeguarding systems and features. The crane provides its own onboard power pack (either electric-hydraulic or diesel-hydraulic, each with closed hydraulic loops) which is located in an enclosed and weatherproof compartment underneath the A-frame. As an option the BOS crane can be upgraded and certified for man riding and for personnel rescue operations.

6 Applications Offshore Cranes In general, offshore cranes are slewing cranes with safe working loads up to 150 metric tonnes, mounted on a bottom-supported or floating offshore installation. Typical duties include load and cargo handling to and from supply vessels, barges or semisubmersibles as well as the support of oil drilling and production activities. Cranes for Subsea Operation Cranes for subsea operation are used to handle loads in water, as well as lower and lift loads to or from the seabed. Heavy Lift Offshore Cranes Heavy lift offshore cranes are lifting appliances mounted on barges, semi-submersibles or other vessels. They are typically used in construction, deconstruction and salvage operations in a marine environment with safe working loads higher than 150 metric tonnes. DSME 6

7 Crane Layout - Structure Overview Liebherr offshore cranes use the most advanced design, engineering and production technology and consist of the following main constructional groups: Design Philosophy / Structural Design The use of modern 3D design tools and finite element analysis allow detailed structural studies, including fatigue analysis and weight optimisation. Our offshore cranes are designed and manufactured in strict accordance with the applicable design rules and regulations and the appropriate norms and standards. Structural Materials All materials for the primary steel structure of the crane and the crane pedestal meet or even exceed the requirements of the certifying authorities. As a standard, materials are certified according to the relevant EN standards, certification level 3.1. Other certification levels are optional and can be quoted upon request (e.g. for low temperature applications, class notation etc.).

8 Slewing Platform and A-Frame The slewing platform is designed to house the machinery compartment, the luffing winch, the counterweight (if installed), the slewing gears and the operator s cabin. Machinery House / Machinery The machinery house and the machinery located inside are protected against weather. Cooling is achieved via hydraulically driven fans. Also situated in the machinery house are the electrical switch compartments, containing the in-house designed Liebherr Litronic crane control system (VME-CAN-Bus 2-line). Features of Liebherr Litronic control system Availability of spare parts: 25 years All upgrades are downward compatible Ease of maintenance no additional software specialist required Designed and tested for maritime environment Spacious arrangement for optimal service accessibility The crane drive consists of a splitter gearbox feeding variable displacement axial piston pumps for the hoisting, slewing and the luffing gear. The splitter gearbox can either be driven by an electric motor or alternatively by a diesel motor. Closed hydraulic circuits technology is used for maximum performance and high efficiency. This technology guarantees a highly responsive, smooth and sensitive operation with a minimum of components, maximising the operating safety even in continuous operation or low/high ambient temperatures (-25 C to +45 C). As an option an arctic temperature package is available, which allows to operate the crane within an ambient temperature range of -40 C to +45 C. Immediate and short system reaction times for rapid and safe operation All crane motions are carried out continuously, precisely and simultaneously with adjustable speed and load High performance density requiring a minimum of power Faster acceleration and deceleration due to low masses of inertia Easy fault-finding and diagnosis due to spare circuits for each crane function Reduced service and maintenance costs compared to open loop systems of equivalent capacity Up to zero reverse power Luffing winch and machinery house Machinery house - diesel engine & splitter gearbox 8

10 5 Boom The boom is a lattice framework construction with the boom tip being a shell structure which accommodates the luffing and main hoist sheaves. The hoist winches (main and auxiliary winches) are located in the pivot section of the boom. A boom extension and auxiliary hoist are available as an optional extra. To achieve the required working outreach, the standard boom pivot sections and standard boom heads can be combined with variable intermediate sections. For the connections between the various boom sections bolted flanges are provided. Luffing and hoisting sheaves on the boom head are lubricated from a centralised greasing point located next to the boom head which is accessible from the boom walkway. A hook garage is available for the main and auxiliary hoist. Boom Pivot Bearing Maintenance-free, capsuled spherical bearings ensure optimal transmission of force and maximal lifetime expectation.

11 Driver Comfort The operator s control desk is fully equipped with all controls and indicators as required for safe and reliable crane operation. The design and layout of the cabin is based on the need for visibility, comfort and operability. It provides a comfortable, low noise environment, essential for ensuring uninterrupted concentration for the driver when operating the crane. Vibrations are reduced through swing equalisers. The window sections are of tinted anti-glare toughened safety glass mounted in an innovative glass frame providing a clear view of the operational area and the handled loads. Control Meets Comfort Optimal position near boom (standard) 70% glass proportion (safety glass) Unrestricted and reliable view for the operator Integrated Litronic touch-screen (one monitor for displaying all relevant information to the operator ) Closed-circuit video system on the jib head with coloured monitor in the cabin (available as an optional item) Air conditioning (standard) Noise- and vibration insulated cabin Operator s cabin 11

13 Environmental Record With its headquarters located in an environmentally protected area, ecological issues have always been high on the agenda for Liebherr. The implementation of economy software, biodegradable oils and special noise insulation throughout its offshore crane range are just a few examples of Liebherr s ecological awareness. Operating Liquids Upon request, all Liebherr offshore cranes can be run on bio-diesel to comply with local regulations and the transition to alternative fuels in customer equipment fleets. Liebherr offers biodegradable oil especially developed for the Liebherr product line. In combination with spectrographic oil analysis techniques, oil lifetime is extended thus providing components such as pumps and motors with even longer lifetimes. Eco-control On request, Liebherr offers a special power management feature for diesel engine driven cranes. This "Eco-control" renders savings in fuel consumption of up to 25% depending on the crane application and therefore results in reduction of noise exposure and environmental contaminants.

Liebherr A Family Enterprise In family-operated companies, ownership merges with active entrepreneurship. This results in characteristic principles. Liebherr is both a family business and a corporation. This does not have to be a contradiction, as the continuous success and steady growth prove. To create top products, the development capacities and production facilities must measure up to the highest standards. This requires substantial investments. From stable locations, Liebherr is following a solidly financed expansion course. The profits made are almost entirely retained within the Group. This provides ample scope for extensive investments. The economic power of the Liebherr Group is best shown by its unusually high equity ratio of more than 50%. This sound economic basis makes Liebherr highly independent in its strategic decisions, and it provides an important basis for future investment and innovation strategies. Offering high-quality products and services which are aimed towards customers needs remains the benchmark. 18

19 Mastering Key Technologies In view of the high quality that Liebherr demands of its products, mastering key technologies internally and keeping core competencies in-house has always been of great importance to the company. Therefore, Liebherr develops and produces crucial components, such as the entire propulsion and control technology, themselves. Further examples are hydraulic components, slip ring elements, and diesel engines. Here, Group suppliers are measured against the best and most efficient external provider. Decentralized and International, Based on Tradition Operating efficiently in manageable, self-dependent units and aiming strategically at emerging markets have always formed part of the basic business principles. Thus, Liebherr regularly invests substantially in further marketing and service companies as well as in new production sites. Entering and expanding into new markets means being locally available to assure the customer receives full and lasting manufacturer support. While maintaining the proven decentralized organizational form, a divisional company structure, whose international expansion is being carried forward, was implemented globally. 19
