Deploying seismic hydrophone cables


Today we had a safety tour around the ship with the Chief Officer. We went through locations of all fire alarms, fire fighter equipment, life belts, immersion suits and muster stations.

Otherwise, not much has happened to day. Most of the time I’ve been talking shit with the navigators and on-board data processors. It’s very useful to get to know them and establish good co-operation before the geophysical data acquisition starts.

The guys on the cable deck are still deploying hydrophone cables. The vessel will be towing eight cables with 100m (330 feet) separation. The length of each cable is 6 km (3.7 miles). The vessel is just steaming slowly and steady in an arbitrary direction. It’s not possible to make sharp turns with the 6km cables behind. Cable deployment is expected to be completed in one or two days. Then the fun starts.

The weather is good; cloudy, but little wind. Wave height is only 3-4 meters (10-12 feet), which makes life on board quite comfortable.

  1. At what height do waves make the trip uncomfortable? And what do your kids think about your excursion?

  2. Up to 5-6 meters (20 feet) wave height is no problem. More than 9-10 meters (30 feet) waves is somewhat unpleasant, due to the rolling and shaking of the ship.

    The kids are used to the fact that I travel quite a lot, no problem. When I get back from the sea, we will go summer-skiing on a glacier. Both the kids and I are looking forward to that >:)

  3. "Wave height is only 3-4 meters (10-12 feet), which makes life on board quite comfortable." - OK, that made me laugh.

    Sounds like you're in your element and having fun!

  4. Your life is INSANE! I am not a risk taker. Nobody in my family will ride a ferris wheel with me, because I sing AMAZING GRACE the whole time (and not very well).

  5. In our offshore operations safety is first priority. Hard hats and hard-tip shoes are required on the work-decks. I think we are more safe here than you are when driving on I-25 >:)
