Seismic vessel and yacht

Report text: Seismic Survey vessel “A” was conducting a marine seismic survey on a North Sea field. Vessel was towing ten seismic streamers at a speed of 4.5kts, each 6000m in length, separated by 100m, at a depth of 8 metres.

Fatigue

Letter Text: Your editorial to issue No. 25 on the topic of “Fatigue” was interesting.  Not in only its content but more importantly in what it did not include. I refer to the minimum manning certificate issued by flag state. This needs urgent attention. As an example, a particular coastal vessel has a minimum manning […]

Cultures of Safety

Report Text: I am writing in response to the report in Maritime Feedback Issue No 19, entitled ‘Medical Indisposition’. I have been a Chief Engineer at sea for many years.  In all these years I have sailed under many superintendents of different nationalities.  In my experience most of the superintendents remember the ISM Code only […]

Use of RADAR – 1

Report Text: Whilst anchoring vessel; unable to proceed due to thick fog, on running into the anchorage an echo was seen on the 3M range on the radar.  The echo was seen to be tracking clear of the vessel, but would pass close.  We had a patrol boat ahead of us and this was dispatched […]

Use of RADAR – 2

Report Text:  I’ve completed a single-handed trans-Atlantic circuit on my yacht & would like to raise a general point about use of radar.  Accepting that there are issues around single-handed and watchkeeping, I found that I could sleep for 40 mins and then pop up to check for shipping; this was OK in mid-Atlantic & obviously […]

Fatigue

Report Text: During one long stand-by (about 10 hours), the duty engineer was so tired he mistakenly made an operational error of shutting down the second cooler (which was already open) in the central cooling system thinking that he was opening the cooler to the system, creating a bit of a panic when the main […]
