Proceedings of 14th International conference „Maritime Transport and Infrastructure - <strong>2012</strong>”SAFETY OPERATION OF PORT STRUCTURES IN BALTIC REGION,INSPECTIONS AND REPAIRING OF LIGHTHOUSES – PART OF PORTSLIFE CYCLE MANAGEMENT SYSTEMVictor Burovenko*, Aleksei Usanov***GT Projekt AS (GT CORPORATION), Tartu mnt. 65, EE-10115, Tallinn, Estonia, E-mail:burovenko@gtcorporation.com*GT Projekt AS (GT CORPORATION), Tartu mnt. 65, EE-10115, Tallinn, Estonia, E-mail:aleksej.usanov@gtcorporation.comAbstractThe article provides a broad overview of Life Cycle Management System for port structures andinformation on the Finnish Code RIL 236-2006 “Satamlaitureiden kunnonhalliinta” (“TechnicalCondition Management of Port Quays”) which is widely used in the Baltic Sea region as a guide formaintenance of port structures. The article also considers experience of GT Corporation onimplementation of repairs of port structures and lighthouses in the Baltic Sea region to ensure safetyoperation, restore bearing capacity and serviceability of these structures.KEY WORDS: port structures, lighthouses, repair, inspection, life cycle managementIntroductionPort structures are considered to be quite expensive facilities with the design life of about 50-100 years. They are subject to intensive damage and deterioration as a result of unfavourableenvironmental conditions as well as engineering factors.Port structures are also subject to a life cycle process. Life Cycle Management (LCM) is amanagement approach to infrastructure construction to achieve cost effective functionality and qualityand to enable a structure’s owner to generate maximum direct and indirect income for minimal WholeLife Cost (WLC) [1].The four fundamental phases of LCM are: planning and design, construction, operation & maintenance, re-use and/or disposal.Our company - GT Corporation was founded in 1990 and since then its associated companieshave been engaged in design, construction, inspection, repair and reconstruction of port structures andlighthouses. During the years of its existence GT Corporation has designed, built and repaired dozensof marine structures and navigational facilities in different regions of the Baltic, White, Black, Azovand Mediterranean Seas.GT Projekt AS as an Estonian subdivision of GT Corporation has been working in the field ofdesign, inspection, repair and construction of port structures and aids to navigation since 1990.Activity of GT Projekt AS is concentrated mainly in the Baltic Sea region. As soon as we have over 20years’ experience in all of the four fundamental phases of Life Cycle Management System, we haveaccumulated a significant knowledge in the integrated approach to the life cycle process of maritimestructures.Complex of negative factors affecting a maritime structure during its operation demands avery attentive approach to technical condition management of the existing port structures. Untilrecently these questions have been considered only individually for particular problems in specialliterature. In the European Union there were no general codes and instructions for applying Life CycleManagement System to port structures.32
Proceedings of 14th International conference „Maritime Transport and Infrastructure - <strong>2012</strong>”In 2006 Finnish Association of Civil Engineers (RIL) developed and published the Code RIL236-2006 “Satamlaitureiden kunnonhalliinta”[2] – “Technical Condition Management of Port Quays”.GT Corporation specialists participated in the development of this Code which also includes practicalexamples of GT Corporation experience in technical condition management of port quays. In 2008under the editorship of our specialists RIL 236-2006 was translated into Russian and published underthe title «Управление техническим состоянием портовых причалов» [3].Since its publication the Code RIL 236-2006 is widely used by port authorities of Estonia andFinland as well as by private contractors engaged in design, inspection and repair of port structures inEstonia, Lithuania and Finland.1. Safety Operation and Life Cycle Phases of Port StructuresA brief description of each of the four fundamental Life Cycle phases specified in PIANCReport n o 103-2008 [1] follows below:1) The planning and design phase encompasses the whole period and all the activities from theinitial idea to elaboration into concepts, outline design and pre-design thru to the detailed design stageof a structure.2) The construction phase commences with the preparation phase followed by on-siteconstruction and finishes with a handover to the owner or operator and ongoing maintenance.3) The operational and maintenance phase relates on the one hand to operational activities andcommercial use of the facility and on the other hand to inspection, evaluation and if deemed necessaryappropriate repairs.4) The re-use and/or disposal phase relates to the end of the service life and /or the technicallifetime. All structures will eventually reach the end of their serviceable life, e.g. due to changes ineconomic, operational, or environmental conditions or for social reasons.The operational and maintenance phase is the longest phase during the lifetime of a structure.The performance criteria such as functional quality and technical quality should be ensured during thewhole lifetime of a structure.Safety is the main criteria among the demands to a structure’s technical quality. Minimumsafety requirements that a structure must meet are normally documented and codified in law in allcountries. Particular safety requirements along with environmental and loading conditions are to beconsidered at the planning and design phase of every structure and included into the design.Table 1 illustrates the main activities to be held within lifetime of a structure corresponding tothe four fundamental life cycle phases in the context of its safety operation.Life Cycle PhaseDesign(Safety of a structure is established)Construction(Safety of a structure is realized)Operation(Safety of a structure is ensured)ReconstructionManagement of Structure Condition during its LifetimeMonitoring of structure conditionRisk analysisSafety requirements developmentQuality controlStatic tests (optional)Prime surveyPreventive maintenance proceduresPeriodic observation and inspectionEvaluation and forecast of technical conditionRepairStart of new life cycleTable 1One of the main goals of the maintenance is to provide safety operation of a structure duringits lifetime. This goal is achieved when a proper maintenance management program is developed andimplemented for the structure.33
