  2. Key Points TMHL aim to change the marine heavy lift market world wide Flexible vessel design secures multiple operational modes thus giving high utilisation and reduced operational and commercial risks Design of vessels and lift system completed and ready for construction Lump sum prices received for TML Vessels and Lift Arm Systems Planned full scale testing programme and simulations of all operations Is very competitive for installation and removal of Topsides and Jackets We will give predictability to our clients with regards to availability of heavy lift systems and cost of marine lift operations World-wide Patent protection TMHL

  3. The Twin Marine Lifter (TML) System The Twin Marine Lifter System is a Revolutionary Simple, Safe and Cost Effective Marine Heavy Lift System The TML System uses two DP Class 3 vessels that also can be utilised for Heavy Transportation, Construction Support, Subsea Intervention, Pipe laying and Accommodation TMHL

  4. The Twin Marine Lifter System • Consists of two Heavy Transport Vessels (HTVs), each with a versatile lifting arrangement consisting of 2 - 6 lifting arms with inherent motion damping capabilities (= low dynamic forces) • The lifting arms are skidded on/off vessels and can easily be removed, thus converting the vessels into heavy transport, construction support or accommodation vessels • The TML system can lift structures designed for monohull floatovers and crane lift with minor requirements for additional steel other than lift points (re-usable) • The TML system can lift very large objects of “any” shape • The TML system can operate in both shallow and deep water • Low dynamic loads – Limited need for strengthening of topsides to be lifted • The TML system operations are very low on emmissions • The TML system can perform both “float-over” operations and “crane” lift operations and can lift “anything” by use of the winch system • No elements are ”new technology”, just a new combination of known systems • Each TML vessel is identical with accommodation for 100 people, helideck, DP class 3 propulsion and submersible capabilities to -22,75 meters TMHL

  5. TML Technology Description • Lifting capacity of up to 34,000 metric tonnes • TML can operate in both shallow and deep water and is therefore water depth independent • Lift arms with 2,500 and 4,000 tonnes lift capacity • Each TML vessel can be equipped with up to 6 arms that can be adjusted to the dimensions of the lifted object • The arms are 75 m long and can be extended 20 meters • The lift force is created by de-ballasting the buoyancy tanks and at the same time ballasting the ballast tanks • TML arm design reduces forces and movements • The two TML vessels lift the offshore structure on/off the transportation barges • The TML system can install and remove both topsides and jacket structures as well as subsea structures TMHL

  6. TML Technology Status The TML System has been developed in close cooperation with DnV and Marintek/SINTEF from day 1: • Marintek has completed seven (7) model tests of the TML system  • Marintek has verified the model test by carrying out dynamic wave response analyses of the TML system using “SIMO” • DNV has prepared a full verification model of the TML system using SIMO and complete sets of analyses have been carried out for typical lifts for all relevant phases of typical lifting operations including phases such as docking/positioning and lift-off • DNV has carried out all relevant hydrodynamic and hydrostatic analyses of the TML system for the lifting modes • The DnV classification of the TML vessels for the 34,000 tonnes system is near completion • Completed detail design for the TML Lifting Arm System including the Control System • Certification of the TML Lifting Arm System is partly completed by DnV Crane Department • DnV has been involved in the design basis of the complete TML system • DnV has undertaken several Hazid’s for typical removal operations using the TML system • Marine operation duration studies performed by London Offshore Consultants • Lump sum prices received for fabrication of both vessels and lift arm system including full scale testing As a result of the above tests, analyses and verification there are no major technical or operational issues outstanding. TMHL are therefore convinced that the TML System will perform its design function safely, efficiently and with minimum environmental impact. TMHL

  7. Application of the TML Technology • Installation of steel substructures (“jackets”) • Installation of platform topsides on steel or concrete substructures • Subsea installations • Mating of topsides with semi submersible hulls and SPARs and TLPs • Miscellaneous, e.g. bridge elements • Can be utilised for ultra-deepwater construction heavy lift operations INSTALLATION • Complete topsides from steel or concrete substructure • Steel substructures • Ships (salvage operations) • Subsea de-installation • Rigs for reef programs REMOVAL • Jack-up rigs • Semi submersible rigs • Modules • Construction elements • Large equipment TRANSPORT TMHL

  9. TML installing a topside – Topside ready for on-loading TMHL

  10. TML Topside Installation – A “one day” operation TMHL

  11. TML Topside Installation – Off-loading from transport vessel Prior to Lift-off 80 – 90% of topside weight is transferred over to TML vessels TMHL

  12. TML Topside Installation – Off-loading from transport vessel Lift-off and clear of HTV within 8 – 10 seconds TMHL

  13. TML Topside Installation – Transfer topside to jacket structure TMHL

  14. TML Topside Installation – Lower topside onto jacket structure Water is dumped from the ballast tanks to lower the topside onto the jacket TMHL

  15. TML Topside Installation – Lift arm released Topsides interface structures and bumper guides are reusable TMHL

  34. Summary TML System Up to 34,000 tonnes lift capacity Low CapEx Low OpEx Can lift topsides that no other system or vessel can wrt geometry Can lift very large jackets and jacket sections (decommissioning) More weather robust than any other lift system Reduced engineering and planning phases Very quick operation Low operational, safety and commercial risks Low energy consumptions – low emissions compared with crane vessels Versatile DP3 Vessels secure revenue in Construction Support and Transportation Markets Decommissioning: Limited topside and jacket preparation, lower dismantling costs onshore Very competitive Good profit potentials even with operator’s cost cut by 50% TMHL
