The engineers and technician work hand in hand to ensure all projects areproperly engineered and operationally practicalOur personnel are experienced and all came from the same background as the mainmarine contractor. We help the major marine contractor plan the work such that thetopside float over activity has the least impact on the vessel construction operations. Weare proactive in highlighting potential issues and ensuring both parties win. OCSunderstands the importance of getting the job done safely and efficiently to minimiseoperational costs for all concerned.PRE QUALIFICATIONOffshore Construction Specialists Pte Ltd.Page 3 of 15

In most cases theseequipment are available and provided by main contractor which OCS will review theirsuitability and proposes checks and verification to ensure the serviceability of theseequipment.Based on the topside float over equipment assessment, OCS will provide a layout of the floatover equipment on the barge assigned by the client. In certain cases OCS can provide thefloat over barge/spread on which to base the required equipment for the float over operation.This layout will then be the basis for the float over barge rig up.4.3Equipment TestingOCS will ensure that all float over support equipment (winches and mooring equipmentincluding power packs, ballast system, power supply, cutting equipment, survey and motionPRE QUALIFICATIONOffshore Construction Specialists Pte Ltd.Page 9 of 15

OFFSHORE CONSTRUCTION SPECIALISTSTOPSIDE FLOATOVERPRE-QUALIFICATION DOCUMENTmonitoring system, etc) is fully tested before leaving the rig up yard. Client representativeswill be invited to witness the testing programme.4.4Load outOCS personnel will be present during topside load out operation to ensure that all aspect ofthe load out that affects the float over will be monitored and any problem observed can berectified immediately and escalation of issues impacting the float over operations at site willbe avoided.4.5Execution ProceduresOCS will provide project specific execution procedures for every project which address allelements of the Topside float over project. These procedures must be approved by the clientprior to offshore operation. OCS will ensure that the procedures address all constraintsposed by specific project site conditions.4.6HAZIDSpecific HAZID and risk identification sessions will be conducted to identify and proposemitigation measures for site hazards which may be posed by operations. This will beconducted as early as possible; otherwise, the latest to be conducted will be just beforetopside loadout.4.7PersonnelOCS will provide a team of qualified personnel to prepare and supervise the work at the rigup yard as well as float over execution as site. Key personnel will be the same for both whosupervise the rig up and testing of the equipment on the float over barge and float overactivity.The OCS typical float over management organization chart as shown in section 3.PRE QUALIFICATIONOffshore Construction Specialists Pte Ltd.Page 10 of 15
