Got a Westfalia OSD 35-0136-067 design 35 on HFO. Separator is passing oil through sludge outlet during operation. What’s been done already:

- all bowl O-rings replaced

- new belt

- new clutch shoes

- spindle checked, condition very good

- water block replaced and tested

Separator reaches speed normally and sludging cycle works correctly. Bowl seems to open/close as it should. No continuous discharge from operating water/dirty water outlet during separation.

Anyone had similar issue on these OSDs?

Hi guys, I have experience on fully refrigerated Lpg gas carriers . I wanna work to Lng fleet but almost company don't want work if you don't have experience on LNG ship. What we will do for this , how can we take experience on it ?????

Hey, Im new to the group. I’m currently enrolled as a Marine Engineering student and I’m looking for an internship/onboard training opportunity as an Engine Cadet onboard a ship. I’m eager to learn, hardworking, and motivated to gain real engine room experience. If anyone knows of openings, companies hiring cadets, or can point me in the right direction, I’d really appreciate it. Thank you!

Hello everyone,

I’m in a difficult situation academically. I was unable to complete high school, and I’ve exhausted all my chances to finish it.

Despite that, I’m extremely serious about building a career in marine engineering. My goal is to start from the very bottom as a wiper and work my way up through experience, sea time, and required certifications. Ideally, I’d like to progress step by step to become a 3rd Engineer, then 2nd Engineer, and eventually Chief Engineer.

My question is:

is this actually possible without a completed high school diploma, or will the lack of one eventually block me from obtaining the necessary licenses and advancing further?

I’m asking specifically about the practical career progression route rather than attending a maritime academy.

I’d really appreciate honest answers from people working in the industry or anyone familiar with maritime licensing requirements.

Wondering about this... I'd like to work on cruise ships when I'm out of school (Georgian College in Ontario), but I feel like cruise ships being foreign flagged may only hire people from cheaper countries.

Greetings,

I've been working on the same ship since I got my license, it's been over two years now. I started as a 4/E and quickly moved up to 3/E. For the past few rotations I've been feeling kind of dull. I have gotten pretty comfortable and I don't seem to have the drive I used to have when I first started. I am not pretending to know everything on the ship, that's never going to be the case. But after having gone through the whole PMS many times, I'm slowly losing interest in learning new things. I'm wondering if it is a sign that I might just need to transfer ship for the sake of novelty and starting from scratch, or is that a deeper indication that I'm getting tired of the job. Has anyone experienced something like that ? I'm curious to hear other people's perspectives and what some have done to remedy similar situations.

Cheers

Hi dear seafarers, please help me with collecting data for my research on improving shore leave procedures for seafarers.

Hi there, I am currently a student in New Zealand studying last year of college, and am wondering about studying a course of maritime engineering in university and eventually a career, and wondering what it is actually like and wether it would be something suitable/enjoyable for me, I am pretty keen on pretty much anything with a engine, welding and fabrication and enjoy fishing off my boat and working on that. What is life actually like working in industry, and what are the advantages/disadvantages of a career in this compared to more traditional home every night kind of jobs. Further, is there plenty of options in industry for work that isn’t based on ships and you do go home every night. Does it at all get repetitive or boring more than a standard job would ? I’m pretty keen to travel as well so is that something that fits well with a career in maritime engineering? Just trying to figure out my options and had seen a decent bit about this and thought it could be something that would be cool and interesting to do and also sounds like pay is decent so that is a bonus.
Cheers for the help

Hey folks, stumped on this issue. Just finished an 8k hour overhaul on a purifier and it started up great on test run. Later I shut it down, and used the supply pump to add some lube oil to a generator sump. In theory, the three way valve should recirculate the oil back and the purifier should have no oil sent to it. well to my suprise the lube oil was dumping out the sludge ports. Later I start it up but before the separator has barely spun up the oil is dumping out the sludge ports before the bowl can even close. super confused, three way valve not recirculating? any help appreciated

Hi everyone,

I’m a French engineering student working on a science project involving underwater acoustics and I’d really appreciate some guidance from people who know more about this field.

My goal is to estimate the number of blades on a propeller based on the sound it produces underwater (basically, acoustic identification of submarines/propellers). I’m already aware of the relationship between rotation speed, blade count, and the resulting frequency (blade-passing frequency), and I’d like to validate this experimentally.

My plan is to test several propellers (for example 1,2,3,4,5,6 blades), but with a key constraint: the blades must be identical in shape across all versions so that the only variable is the number of blades. That’s where I’m running into trouble.

I don’t have much experience with 3D modeling. I can probably find existing models and edit them in SolidWorks, but I’m not sure if that’s the best approach. Would it make sense to hire someone (e.g., Fiverr) to create a parametric model where I can just change the number of blades while keeping everything else constant?

My main questions:

• What propeller shape should I use as a baseline for this kind of experiment?
• Do different blade shapes significantly affect the acoustic signature underwater?
• Should I test multiple shapes, or is it better to stick to one standardized geometry?
• What types of propellers are commonly used on submarines? Are there “typical” designs I should look into (e.g., skewed blades, specific profiles, etc.)?
• what do you think of my appraoch generally (as submarine experts)?

I’m trying to keep the experiment as controlled and realistic as possible, but I’m a bit lost on the design side. If anyone here has experience with marine propellers, underwater acoustics, or naval engineering, your input would be incredibly helpful.

Thanks a lot in advance for your help!

edit : TLDR : French engineering student trying to identify the number of propeller blades from underwater sound (blade-passing frequency). I want to test 1–6 blade propellers while keeping blade shape identical, but I need advice on propeller design, submarine propeller types, and whether blade shape strongly affects the acoustic signature. Also wondering if I should hire someone for the CAD modeling.

Hello! Good day friends and seniors!

I want to discuss and hear experiences out about our very first ships as a 4th engineer ( 3E in korean companies) after your cadet contract.

- How was your first month?

- any breakdowns and emergencies happened during ur first month?

- Socials and relationships with good/bad people?

- any unfair treatment, biased workplace, good appreciations, accusations, breaking of MLC related, happy moments , parties ,etc

- How do u finish assigned jobs by C/E and 2/E

- mistakes we have done during that first ship

And anything u wanna share ..😊

Hello everyone, I am a Metallurgical and materials science Engineer with a Bachelor's degree in Metallurgical Production Engineering from Cairo University, specializing in the field of petroleum and mining. I have a strong interest in transitioning to the maritime engineering field. I would like to ask all of you: at a global level, are the entry requirements for the maritime academy in Egypt the same as in other countries? If I want to enter this field, are there courses or pathways that can lead me to become a marine engineer (3th engineer), then 2nd, then 1st, and ultimately Chief Engineer? What would be the best route or advice you have for pursuing a career in marine engineering? Thank you in advance!
