Employees are not allowed to use the customer's computer for personal e-mail use. It is only to be used for business purposes.
Misuse of business computers can lead to disciplinary action.
Some vessels provide e-mail facilities for employees. If you are assigned to a ship that does not have public computers, you may utilize the computers at the internet cafés located at most ports.
Email Etiquette
All business messages must always remain professional in content.
When writing and responding to emails, keep in mind that different cultures may few your harmless punctuation as shouting or rude. Always read your email again before sending and remove any questionable items.
Avoid using bold and underlining to get a point across.
Keep exclamation points to a minimum and ensure they would not be confused with shouting or anger
