Abstract

The Global Positioning System (GPS) is the primary source of position for modern ship navigation, and its value depends on how well it is integrated with other bridge equipment such as RADAR/ARPA, the Electronic Chart Display and Information System (ECDIS), and the Automatic Identification System (AIS). This study analyses the use of GPS for determining ship course and position on the tanker MT New Winner, identifies the factors that hinder its optimal use, and proposes solutions. A descriptive qualitative design was applied over 12 months of sea service, using observation on the bridge, semi-structured interviews with four deck officers (the Master and the Chief, Second, and Third Officers), and a review of manuals and literature. While the vessel was sailing in the Makassar Strait, GPS1 (Furuno GP-150), the only receiver interfaced with RADAR/ARPA, ECDIS, and AIS, failed. Although GPS2 (GP-170) still displayed the ship’s position, it was not connected to the other systems, so the Master had to plot the position manually every 30 minutes to avoid the risk of grounding. The failure was caused by a damaged GPS antenna and its mounting, broken antenna shock absorbers, poorly maintained cables and keys, and an inadequate power supply. The study concludes that GPS use on board was not optimal because of the lack of redundant integration and insufficient maintenance. Connecting both GPS units to all navigation systems, maintaining the antenna, cabling, and power supply regularly, and practising alternative position-fixing methods are recommended.

Abstract

Negligence during the navigational watch is a major contributor to collisions at sea, even though the International Regulations for Preventing Collisions at Sea (COLREG) 1972 and the STCW Convention, as amended in 2010, set clear requirements for lookout, assessment of collision risk, and watchkeeping arrangements. This study analyses efforts to prevent collision hazards caused by negligence during the navigational watch on the general cargo ship MV Francisca. It was carried out during the authors’ sea practice from 5 August 2022 to 5 August 2023 using a descriptive qualitative design, with data collected through direct observation, interviews with watchkeeping officers and crew, and documents such as the logbook and standard operating procedures. The units of analysis were the officers of the watch and the navigation equipment used during the watch. A near-collision on 25 January 2023, during a voyage from Rotterdam to Reykjavik in Scottish waters in snow and waves of about 6 m, served as the case study. The Second Officer ignored repeated reports from the cadet that a fishing vessel on the starboard side was less than 1 nautical mile away with a decreasing closest point of approach, because he was completing a passage plan that should have been prepared before departure; a collision was avoided only by a late alteration of 75° to starboard and a reduction to dead slow ahead. The Chief Officer had also left his 16:00–20:00 watch to the Second Officer outside the latter’s watch hours. The study concludes that watchkeeping on the MV Francisca did not fully comply with COLREG 1972 and STCW, particularly regarding continuous lookout, response to reports, handover, and avoidance of distracting tasks. Stricter watchkeeping discipline, better use of radar and ECDIS, effective communication within the bridge team, and training are recommended.

Abstract

The auxiliary engines that drive a ship’s generators must operate reliably, and their piston rings are critical for maintaining compression and preventing the leakage of combustion gases. This study identifies the causes of the piston ring damage in an auxiliary engine of the MV Fatime and the measures taken to repair it and prevent recurrence. A descriptive qualitative design was used, with data collected through observation, interviews with engineers and crew, and technical documentation, including engine operating records, during the authors’ sea practice. On 14 January 2024, during a voyage from China to Brunei, the auxiliary engine stopped, and the Third Engineer found the piston of cylinder No. 3 sticking. Dismantling revealed a broken compression ring and a worn and corroded oil ring. The operating records showed that, compared with the normal condition, the exhaust gas temperature of cylinder No. 3 fell progressively from 325 °C to 265 °C over 24 hours and the engine speed fell from 714 to 660 rpm, while the other cylinders remained at about 328–332 °C; after repair, cylinder No. 3 returned to 328–331 °C and the speed to 719–720 rpm. The damage was attributed mainly to exceeded running hours and inadequate lubrication, with cooling problems and contaminated intake air as possible contributing factors. The broken rings were replaced and the cylinder head and piston were cleaned. Lubricating oil changes according to the maker’s schedule, monitoring of running hours and of individual cylinder exhaust temperatures, and regular measurement of ring clearances are recommended.

Abstract

Penelitian ini bertujuan untuk menganalisis olah gerak kapal MV. Aquagenie saat berlabuh jangkar di Yeosu Anchorage, Korea Selatan, serta mengevaluasi faktor-faktor penyebab insiden jangkar larat yang terjadi. Kapal sebagai sarana transportasi laut tidak terlepas dari risiko operasional, terutama saat menghadapi kondisi cuaca buruk, arus, dan angin kencang. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik pengumpulan data melalui observasi langsung, wawancara mendalam, dan analisis dokumentasi. Hasil penelitian menunjukkan bahwa insiden jangkar larat yang dialami MV. Aquagenie pada 25 Juli 2023 disebabkan oleh beberapa faktor utama, yaitu pemilihan lokasi labuh yang kurang tepat, panjang rantai jangkar yang tidak memadai, serta kelalaian dalam dinas jaga saat cuaca mulai memburuk. Kapal berlabuh di area outer anchorage (D-1) tanpa bantuan pandu, dengan kondisi awal cuaca yang baik. Namun, cuaca kemudian berubah drastis dengan kecepatan angin mencapai ±35 knot, menyebabkan jangkar tidak mampu menahan kapal sehingga kapal mengalami pergeseran posisi (larat). Sebagai langkah mitigasi, penelitian ini merekomendasikan pelatihan khusus bagi awak kapal, peningkatan koordinasi dalam dinas jaga, serta pengawasan rutin terhadap kondisi jangkar dan peralatan pendukung selama kapal berlabuh jangkar.

Abstract

Difficulty in starting a ship’s main engine can delay departures, disrupt operations, and create safety risks. This study analyses the factors that caused the initial starting difficulty of the starboard main engine on the AHTS SK Canopus, the impacts of the failure, and the corrective measures applied. A descriptive qualitative design was used, based on direct observation and documentation on board over a 12-month period; the battery data were processed with SPSS (paired samples statistics, paired samples correlations, and the Wilcoxon signed-rank test) and checked with basic electrical formulas. On 25 July 2023, the starboard main engine failed to start during manoeuvring because the battery voltage was below the specification in the manual book, as the battery had exceeded its service life. Compared with the normal condition, the abnormal battery required 13.3 hours to charge instead of 6.6 hours and drew a charging load of 6.43 A instead of 3.18 A, while the overheated battery showed a load of 4.83 A. After the battery was replaced according to the manufacturer’s specification, the charging time fell to 3.3 hours and the charging load to 1.6 A, and the statistical indicators returned to those of the normal condition. The study concludes that battery condition is a key factor in the starting reliability of the main engine and recommends periodic monitoring of battery voltage and charging time within the planned maintenance system to prevent similar failures.

Abstract

The efficiency and performance of shipboard generators are crucial for safe and uninterrupted vessel operation, and the condition of the exhaust gas is an important indicator of combustion quality and engine health. This study analyses the exhaust gas condition of diesel generator No. 3 (Caterpillar C18) on the offshore vessel Rawabi 49, owned by Rawabi Vallianz Offshore, and its effect on engine power. A descriptive case study was conducted on board for approximately one year, using direct observation of generator operation and inspection of the air intake and exhaust systems, the manufacturer’s specifications and operating limits, and a review of the relevant literature. The observations showed an abnormally high exhaust gas temperature on generator No. 3. Inspection traced the problem to a dirty and clogged air cleaner, which reduced the air flow to the engine, upset the air–fuel ratio, and caused incomplete combustion and a loss of output power. Insufficient maintenance of the generator also forced the engine to work harder under high load, which tends to increase nitrogen oxide and particulate emissions. Eleven factors that can raise exhaust gas temperature were identified, including fuel quality, injector and turbocharger condition, load, cooling, and valve clearance. Regular cleaning or replacement of the air cleaner according to the maker’s schedule, monitoring of air inlet restriction and exhaust temperature, and planned maintenance are recommended to restore engine power, improve fuel efficiency, and reduce emissions.

Abstract

Anchoring in open and congested anchorages exposes ships to operational risks, particularly when weather, current, and wind conditions change rapidly. This study analyses the manoeuvring of MV Aquagenie 1 during anchoring at Yeosu Anchorage, South Korea, and evaluates the factors that caused the anchor dragging incident that occurred there. A descriptive qualitative design was used, with data collected through direct observation on board, in-depth interviews with the Master, the Chief, Second, and Third Officers, and a helmsman, and analysis of the ship’s operational documents. On 25 July 2023, the ship anchored in the outer anchorage (D-1) without a pilot, paying out six shackles of anchor chain (about 165 m) in initially good weather. The weather then deteriorated sharply, with wind speeds reaching about 35 knots, and the anchor could no longer hold the ship, which began to drag. The analysis identified three internal factors, namely an anchoring position that did not account for the risk of bad weather and the type of seabed, an insufficient length of chain for the conditions, and ineffective anchor watchkeeping as the weather worsened, together with two external factors, namely strong wind and waves and a sandy mud seabed. To prevent similar incidents, the study recommends specific training for the crew, adjustment of the chain length to the water depth and the weather forecast, closer coordination and monitoring during the anchor watch, and routine inspection of the anchoring equipment.
