Όπως κι αν γίνει η επιβίβαση, ακολουθούμε τον λιμενικό.

Here όπως κι αν means however or no matter how.

So:

• Όπως κι αν γίνει η επιβίβαση = However the boarding takes place
• more naturally in English: No matter how boarding is done

This is a common Greek pattern:

• όπως κι αν + subjunctive

It introduces an indefinite/concessive idea: the exact way something happens does not change the main point.

Κι is just a shorter form of και.

So:

• κι αν
• και αν

Both are possible, but κι αν is extremely common and sounds natural in everyday Greek. Before a vowel, Greek often uses κι instead of και for smoother pronunciation.

In this sentence, όπως κι αν is a very common fixed combination.

Γίνει is the aorist subjunctive of γίνομαι (to happen, become, take place).

In this sentence, it means something like:

• however the boarding happens / takes place

Greek uses the subjunctive after expressions like όπως κι αν, because the clause refers to something indefinite, possible, or not yet fixed, not to a specific completed event.

So:

• γίνεται would mean is happening / happens in a more straightforward indicative sense
• γίνει after όπως κι αν gives the meaning however it may happen

Because η επιβίβαση is the subject of γίνει.

The structure is:

• γίνει η επιβίβαση = the boarding happens / takes place

So η επιβίβαση is not an object here. It is the thing that happens.

A rough breakdown:

• η = the
• επιβίβαση = boarding / embarkation

Since it is the subject, it stays in the nominative.

Επιβίβαση means boarding or embarkation.

It is the noun related to getting onto:

• a ship
• a ferry
• a plane
• a bus, etc.

In this sentence, because of λιμενικός, the context is most likely boarding a ferry or ship.

It is a fairly standard and somewhat formal word, often seen in:

• announcements
• signs
• official instructions

Literally, ακολουθούμε means we follow.

But in Greek, the present tense is often used for:

• instructions
• general rules
• practical guidance

So here it does not necessarily mean we are following right now. It can mean something like:

• we follow the port officer
• we should follow the port officer
• the procedure is to follow the port officer

This kind of present tense is very natural in instructions and announcements.

Greek often uses first person plural for instructions in a softer or more inclusive way.

So ακολουθούμε τον λιμενικό can feel like:

• we follow the port officer
• let’s follow the port officer
• passengers should follow the port officer

This is common in notices and spoken instructions because it sounds less abrupt than a direct command.

A direct imperative would be:

• Ακολουθήστε τον λιμενικό. = Follow the port officer.

That would sound more directly like an order.

Because τον λιμενικό is the direct object of ακολουθούμε.

• ακολουθώ κάποιον = I follow someone

So the noun must be in the accusative:

• ο λιμενικός = nominative
• τον λιμενικό = accusative

That is why the article changes to τον.

Here λιμενικός means a port officer or coast guard officer.

The word comes from λιμάνι (port, harbor), and in modern Greek it often refers to a member of the port police / coast guard service.

In ferry or harbor contexts, English translations may vary:

• harbor officer
• port authority officer
• coast guard officer

The exact best translation depends on context, but grammatically it is simply the officer that passengers are being told to follow.

Yes. The sentence begins with the subordinate clause:

• Όπως κι αν γίνει η επιβίβαση, ...

This sets up the idea first:

• no matter how the boarding happens...

Then the main clause gives the instruction:

• ... ακολουθούμε τον λιμενικό.

Starting with the όπως κι αν clause makes the sentence sound more natural and emphasizes that the procedure stays the same regardless of the boarding method.

Greek word order is fairly flexible, but this order is very natural for this meaning.

You can roughly map it word by word, but a natural English translation needs some adjustment.

Very literal:

• Όπως κι αν γίνει = As/however it may happen
• η επιβίβαση = the boarding
• ακολουθούμε = we follow
• τον λιμενικό = the port officer / coast guard officer

A more natural English version would be:

• However boarding takes place, we follow the port officer.
• No matter how boarding is done, we follow the port officer.

So the grammar is not hard, but the Greek structure is more natural if translated by sense rather than word-for-word.
