A LOCKED-POSITION MONITOR FOR IMPROVING SAFETY OF RELEASE HOOKS IN ENCLOSED LIFEBOATS

Repeated casualties caused by inadvertent release of lifeboat release hooks during drills and inspections have attracted the attention of the International Maritime Organization, which correspondingly amends the Life-Saving Appliance (LSA) Code in the international convention for the Safety of Life at Sea. This study proposes novel installations of locked-position monitors on release hooks for monitoring and safety checks. With the installation of locked-position monitors near unsealed pull rod, upon lifting the lifeboat from the water, the sensors can initiatively detect whether the release hooks are in a locked position. If the release hooks are not in the locked position for any reason, audible alarms are activated, warning lifeboat operators to cease operations and wait for further inspection. The example provided in this research indicates that locked-position monitors can be implemented on lifeboats to reduce accidents resulting from malfunctioning lifeboat release hooks, thereby promoting a safer working environment for all seamen at sea.

Prediction of Maneuverability in Shallow Water of Fishing Trawler by Using Empirical Formula

The length between perpendiculars (LBP) of most fishing vessels is less than 100 m. Thus, they are not subject to the International Maritime Organization (IMO) maneuverability standards, affecting research on maneuverability. However, upon referencing the statistics of marine accidents related to vessel maneuvering, the number of marine accidents caused by fishing vessels is 3 to 5 times higher than that of merchant ships. Therefore, systematic and consistent research on the maneuverability characteristics of fishing vessels is surely required. In particular, a fishing vessel frequently enters and departs from the same port and often sails at high speed due to familiarity with the characteristics of the situation, which may cause maneuvering-related accidents. In this study, the maneuverability of a fishing vessel in shallow water was predicted using an empirical formula. The results of this study are expected to not only be of great help in conducting simulations when analyzing marine accidents involving fishing vessels, but will also provide unique parameters of fishing vessels that lead to developing autonomous vessels.

DAMPAK IMPLEMENTASI GREEN SHIPPING PADA PERUSAHAAN PELAYARAN

Penelitian ini bertujuan untuk mengevaluasi implementasi Green Shipping pada industri Perkapalan dan Transportasi Laut Kalimantan Timur yang sesuai aturan International Maritime Organization yang dimuat dalam Marine Pollution Regulasi Annex VI. Data yang digunakan dalam penelitian ini adalah data sekunder berupa data spesifikasi kapal TB. Rezky 27. Alat analisis yang digunakan dalam penelitian ini adalah analisis kuantitatif yaitu mengolah data perhitungan jumlah konsumsi bahan bakar, menghitung faktor emisi, simulasi perhitungan penggunaan bahan bakar dan membandingkan biaya konsumsi bahan bakar. Hasil penelitian menemukan bahwa berdasarkan perhitungan konsumsi lima bahan bakar yang dapat digunakan kapal, bahan bakar LNG memiliki biaya konsumsi paling kecil dibanding bahan bakar lainnya namun ketersediaan LNG sebagai bahan bakar alternatif masih kurang untuk memenuhi kebutuhan industri pelayaran selanjutnya biaya konsumsi bahan bakar Solar dan HSFO (High Sulfur Fuel Oil) memiliki biaya yang kecil namun mengharuskan kapal menggunakan scrubber sehingga berdampak pada perusahaan pelayaran yang harus mengeluarkan biaya investasi untuk pembelian Scrubber. Penggunaan bahan bakar methanol sebagai bahan bakar alternatif karena ramah lingkungan dapat digunakan di industri pelayaran namun diperlukan modifikasi dan penyesuaian pada mesin kapal sehingga berdampak pada biaya yang harus ditanggung oleh perusahaan. Penggunaan bahan bakar LSFO (Low Sulfur Fuel Oil) berdasarkan perhitungan konsumsi bahan bakar memiliki biaya yang paling tinggi diantara bahan bakar lainnya namun bahan bakar ini adalah bahan bakar yang sesuai dengan aturan IMO.

Maritime Cyber Security: A Global Challenge Tackled through Distinct Regional Approaches

Maritime cyber security is an emerging issue that requires immediate attention, according to the International Maritime Organization (IMO). Feedback received from global shipping professionals indicate that a common threat to the industry, such as cyber security, is dealt with differently among industry practitioners around the globe. Data collected from two targeted focus groups (one in Europe and the second in Asia, two leading groups in the maritime transport sector) demonstrated that, based on technology adoption maturity, cyber security is perceived differently between these groups. The COVID-19 pandemic has highlighted these differences. Our findings lead to useful intelligence that will inform key maritime decision makers, both in meeting the IMO requirements and preparing the organization to address cyber risks.

New opportunities for seafarers owing to reduction emission and arising the number of Dual fuel vessels

Nowadays one of the main goal of International Maritime Organization (IMO) is to reduce pollution by vessels over the world. Due to this they implemented in MARPOL Annex VI the requirements for any gas vessel’s emissions which are setting the limits and timelines of compliance. To overcome this problem IMO adopted on 15th July 2011 the commence measures for improving vessel’s energy efficiency plan and reducing emissions of greenhouse gases (GHG). The main strategy of GHG envisages the reduction of international shipping in carbon intensity (reducing CO2 emissions from transport activities on average for international shipping from 40% to 70% by 2050). According to this, growing the problem concerning new opportunities for seafarers. That was managed on example by crewing company Nordic Hamburg at implementation the new trainings.

Risk Assessment Fishing Vessel Based for the Intact Ship Stability

Application of safety assessment and risk analysis using a risk-based approach for ship stability in ship operations at sea. However, there are currently no specific criteria and computational methods for risk assessment of ship stability. Based on the stability requirements for fishing activities at sea, the ship stability criteria will be explained in detail in this study. Calculation of stability used to obtain the GZ enforcement arm is carried out with the help of software for the shaking period using the International Maritime Organization (IMO) formula. Next, how to calculate parameters and determine certain coefficients for risk assessment of ship stability, and how to redraw the stability curve. Finally, proposed method is applied to ship model with comments and recommendations for monitoring to provide and overview. The study result indicate that the five loading conditions that occur on the ship have good stability by the criteria set by the International Maritime Organization (IMO). The value of GMt in each condition includes condition 1 and so on, 0.48; 0.48; 0.47; 0.46; 0.43. The results are presented in the form of F-N. Finally the sensitivity of the model is evaluated along with the assessment of associated uncertainties. The FN graph represents acceptable areas and unacceptable areas.

Determination of the LNG Bunkering Optimization Method for Ports Based on Geometric Aggregation Score Calculation

Owing to stricter environmental regulations of the International Maritime Organization (IMO) 2020, the demand of liquefied natural gas (LNG) bunkering is expected to grow by approximately 15% during 2020–2025 along with increased investments in eco-friendly ships by global shipping companies. Thus, determining optimal methods for LNG bunkering using existing ports that lack LNG bunkering infrastructure is necessary. Here, a method is proposed to determine the optimal LNG bunkering method for existing ports. Analyzing previous studies, we selected four evaluation factors: assessment of LNG supply for ships, suitability of fuel supply, risk of spillage, and domestic and international standards, which were used to calculate a geometric aggregation score via normalization, weight, and aggregation for selecting an appropriate LNG bunkering method. The analytical results indicated that the ship to ship (STS) method, evaluated based on the size and type of ships, is optimal for the Busan port. This is expected to contribute to the competitiveness of ports and their safety and economic feasibility by serving as a basis for determining the optimal LNG bunkering implemented in existing ports. It is necessary to expand the follow-up research to improve the evaluation method by aggregating more improved data through real cases.
