Hazardous occurrence related to premature commencement of loading LNG

Challenges faced and Lessons to be learned Confidential Hazardous Incident Reporting Programme (CHIRP) has received a report regarding premature commencement of loading LNG.Report text:"Our LNG (Liquefied Natural Gas) carrier recently had a problem at a loading terminal. There was the normal discussion between the Loadmaster and the Chief Officer regarding safety matters etc. On completion of the Cold Emergency Shut Down test the Loadmaster asked if the vessel was ready to commence loading. The Chief Officer explained that prior to loading the ships lines had to be cooled to110C. At that time the warmest part of the system was at -28C and therefore not adequately cooled."A short time later the Loadmaster asked if they were ready to load but still the lines were not cooled to the correct temperature. The Loadmaster left and returned within minutes and advised the Chief Officer that loading had commenced at a rate of 1000m/hr. At this time the vessel was not lined up for Loading. The terminal was given a Letter of Protest:"The procedure for loading of LNG ships at our terminal has not been changed. But during the cool down operation and start of loading of your good vessel, the terminal procedure for ...

Hazardous occurrence related to navigation near a busy anchorage

Challenges faced and Lessons to be learned Confidential Hazardous Incident Reporting Programme (CHIRP) has received a report regarding navigation in or near to a busy anchorage.Report text:"My vessel, a large laden tanker, was making its approach towards a busy anchorage. At the time of the incident we were steering a course of 225 True with a speed of 06 knots, with many ships at anchor on my starboard side."We saw a bulk carrier just abeam on our port side. It was on converging course and her speed and my speed was almost equal. VHF Contact was made with the vessel to ask her intentions. I requested them to slow down & pass from my stern, but they refused and said that they will maintain their course. I then noticed that the bulk carrier had increased a speed so as to cross my bow from our port side. When she was 4 points on my port bow at a distance of 6 cables, I stopped my engine & then put it to slow astern. She finally passed at a distance of 3 cables from my bow."I was in embarrassing situation as I could not go starboard due to anchored vessels."The bulk ...

The danger of distraction while operating the ship

Challenges faced and Lessons to be learned Confidential Hazardous Incident Reporting Programme (CHIRP) has received a report regardingthe danger of getting distracted while operating the ship.Report text:"This incident I would rate as a potentially hazardous one, interfering with the effectiveness of the Bridge Team."I had boarded the ship at the pilot station for inward transit to the berth. The Pilot/Master exchange was completed with no problem and we proceeded inwards. About 45 minutes into the Pilotage, the bridge door was flung open and a Superintendent strode onto the Bridge and proceeded to give the Master a good 5 minute tirade in the middle of the Bridge. I was not particularly concerned at this time, the ship was on a straight run with no other traffic around - it was slightly distracting but, if anything, it was extremely embarrassing for the Master to be on the receiving end of this language in front of me, the helmsman and the officer of the watch. After a while the Superintendent disappeared and everything settled down and carried on as normal, including discussions on the berthing arrangements, allthat had been previously discussed at the exchange but which is often best repeated before it happens."Subsequently ...

Hazardous occurrence related to engine room procedures

Challenges faced and Lessons to be learned Confidential Hazardous Incident Reporting Programme (CHIRP) has received a report regarding engine room procedures.Report text:"My offshore support vessel was standing by a drilling rig. We were using our dynamic positioning system. The ship's propulsion is generated by four diesel electric generators. The propulsion system is combination of two bow thrusters and two stern azimuth pods. The engine room watch consists of one engineer always on watch. The charterer's standing orders are to maintain constant watch in engine room during DP operations, and, depending on power load, 2 or 3 diesel generators are always to be running."On this occasion, the weather deteriorated. Rain squalls were frequently passing with wind gusts up to force 7, with swell to 1.5 metres. The engine room was attended but only one generator was running.Summary:A combination of a squall and big waves resulted in large power demand from propulsion system.The second diesel generator started in auto mode but did not put itself on line. This resulted in alarms in the machinery space.The third diesel generator then started in auto mode but did not put itself on line, with further alarms.The fourth diesel generator started in auto mode. This did ...
