Engine Room: The Heart of NOAA Ship Oregon II


Mission: Long Line Shark/ Red Snapper survey Leg 1
Geographic Area:32 nautical miles SE of Key West Florida
Date: July 28, 2018
Weather Data from the Bridge: Wind speed 11 knots, Air Temp: 27.6c, Visibility 10 nautical miles, Wave height 1 foot
Science and Technology Log: As we move through the Gulf of Mexico headed to our first research station, I didn’t have a job most of the day, so I sought to find out more information about what makes the great Oregon ll function to serve it’s crew of 28. One of the Engineers kindly offered me a tour of the engine room to see what lies below the service decks.
The ship is powered by twin 900 horse power engines that turn the propeller shaft up to 12 knots. When sailing between work stations, generally both engines are used, and when long line fishing begins, only one engine provides power as the ship moves around 2- 3 knots. The ship holds up to 70,000 gallons of fuel, and when both engines are running,1,000 gallons are used daily. There is also a bow thruster engine near the front of the ship that is much smaller and helps with finer movements at the dock, in stations, or when seas get rough.

There are 2 large electrical power generators that provide electricity to the ship for the multitude of research computers and data collectors. While out at sea, Oregon ll is always tracking weather data, water quality, live radar from above the ship, and also sonar from below the ocean. The generators also provide power for all the creature comforts you would need in any living environment, as this ship is the crew’s home during each leg of the trip. At times when less power is needed, one generator is shut down to conserve energy for later use.
The Oregon ll  also provides it’s own clean water for equipment and human consumption. The Water Purification System uses Reverse Osmosis to take salt water from the ocean and turn it into potable water to wash, cook, clean with, and drink. A Reverse Osmosis System uses high pressure and pushes impure water through a semi-permeable membrane which allows clean water through the membrane, while allowing impurities (such as salt, bacteria, and sediment) to be blocked from coming through, and discharges the impurities back into the ocean.

Personal Log: I am having a great time getting to know the crew and their many jobs around the ship, and how each one affects the other. This symbiotic relationship is the heart of what makes every mission successful. There are the Ship’s Officers who chart the course, drive the ship, and oversee all Crew Members. The Deck Department makes sure the work areas are safe and equipment is working correctly. The Fishermen are in charge of the process of the Long Line Survey, from preparation, to process, to clean-up. The Engineering Department makes sure the interior of the ship and it’s equipment are functioning properly, which is a very wide ranging. I certainly wish I had these guys around my house during those tricky repairs!
The Steward Department is in charge of ordering, cooking, serving, and cleaning up of all meals for the crew. Finally, the Electronic Department has the complicated job of installing, operating, and fixing any electronic equipment. Let me tell you, there are miles of wires running through this ship and all of it is used to make the mission successful. All data is continually collected, and preserved for later study. Some of the water and weather data is uploaded to the NOAA website for the public’s use as well.
I really enjoyed hearing the wide ranges of places in America the Oregon ll crew come from. It is also impressive to hear the various places all around the world they’ve sailed before joining NOAA, and which other NOAA ships they’ve been crew members on. The diverse experience each crew person has in their field has really helped the mission many times over since I’ve been here. One thing I know is true is that each of them is happy to tell you about their families, and how much they love them and miss them while they’re away. Many of them have long seasons away from the ones they love, and count the days until they can come home.
Fun Fact: NOAA Ship Oregon ll turned 50 years old last year, and was honored for making the half century mark of service. It was built in 1967, right in it’s home port of Pascagoula, Mississippi
