Currently, monitoring of facilities is only done by request to assess heavily damaged components on the top side of facilities before a repair. However, having this only method prevents the components to be repaired earlier to save costs and left more critical components such as piles to remain unchecked, in which this may lead to complete structural failure. A simple maintenance management system has been proposed to be used by national port operators which consist of monthly monitoring and yearly inspection while still taking the limitations of national port operators in the branches into account. An example of monitoring activity proposed in the system is presented and effective for capturing the general condition of a berth structures as well as the facility health indicator.

INTRODUCTION Port is one type of the infrastructures that are consistently exposed to both harsh environment and heavy loading from human activities. Port facilities, especially its berth structures, receive loads from the environment as well as become subjected to marine growth. Ship berthing and mooring forces acting on the bollards placed on berth front also affects the durability of the berth structures. In addition to loads from the ship, the upper side of berth structures is also occasionally loaded by heavy vehicles and machinery such as cargo trucks and cranes. This environment and the human activities on the port led to the high amount of deterioration of facilities as well as lower lifespan design expectation compared to other types of infrastructure. As mentioned by International Navigation Association [1] and Port Technology Group [2], compared to 120 years of highway or rail structures lifespan, typical port structures have a relatively lower design lifespan of 50 to 80 years due to its harsher environment. Zhang et al. [3] have done a simulation based on the facility data from Tokyo Port using Markov chain model to model the deterioration rate of the port. According to the simulation result, it was found that the deck-on-pile structure components quality on the Tokyo Port degrades quickly in the beginning and slows down as the structure deterioration level becomes higher, typically after 10 years. This port deterioration problem becomes a challenge to port operators around the world including countries in Asia. In 2009, a three-year program from the Port Technology Group under the ASEAN-Japan Transport Partnership Program was started to overcome this problem by making a guideline to strategic maintenance for port structures. One of the participants of this group is in Indonesia, which assigns PT. Pelabuhan Indonesia I to IV as the operators of the national port. Some of the facilities of Indonesian national port operators (NPOs), especially the berthing facilities, have been highly deteriorated especially for port branches outside of Java Island. The high level of deterioration across facilities owned by NPOs is mainly caused by the lack of regulated facilities maintenance system. Currently, monitoring of facilities is only being done by request or when a repair is going to be conducted to measure the damage and calculate the repair cost. While this monitor-on-demand method relatively works for the components on the top side of port structures, regular monitoring can detect lighter damage and may save repair or replacement cost compared to the repair of heavily damaged components. Moreover, components on the lower side of the berth structure tend to be overlooked if the current monitoring method is preserved since they are not easily visible. A completely corroded pile, for example, may lead to the failure of the berth structure as shown in Fig. 1.
