A new Mariner employed by SEACOR Marine would become a crewmember aboard an offshore vessel in the Gulf of Mexico. While working in this unique working environment, the Mariner may be assigned to a vessel for extended periods of time. The most common schedule aboard our vessels is 28 days on and 14 days off, but we do have vessels with other schedules.

At times weather conditions will be difficult. Over time, the Mariner would encounter varying weather conditions with seas being calm to rough and temperature ranges typical of the seasons. Motion sickness may occur.

The Mariner must prepare for life at sea. This involves extended time away from family, friends, and loved ones. There are times when many days may go by before having the opportunity to make contact with home. The Mariner must ask himself/herself if they and their family can adapt to these conditions.

A new Mariner’s initial assignment would be to complete a training program, which has two main objectives. First, it is designed to loosely simulate life on board a vessel under which the Mariner will be required to work. Secondly, it is designed to provide the Mariner with valuable knowledge and training, necessary to enable the Mariner to carry out his/her duties in a safe and efficient manner. For additional information regarding this training, click here.

A new Mariner would be hired as a Deckhand or as an Ordinary Seaman if they have obtained their Merchant Mariner Document. Deckhands have little or no previous experience and their main duties consist of housekeeping, general maintenance, loading or off-loading cargo, watch keeping and contributing to the safe navigation of the vessel. A deckhand is encouraged to get their Merchant Mariner document (MMD, commonly referred to as a “Z” card) in order to work on larger vessels. Information on obtaining an MMD is available at www.uscg.mil/nmc.

A minimum qualification to be retained in any position on a vessel including the position of Deckhand is to obtain a Transportation Workers Identification Card (TWIC). Information on the TWIC can be obtained from the website www.tsa.gov/twic.

Advancement is encouraged, and we provide eligible employees with training assistance to help them achieve their goals. It usually takes a Deckhand, with no previous knowledge, approximately six months to advance to an Unlicensed Engineer position if he/she is willing to dedicate their time to learning the engine room.

All vessels are supplied with bed linens, blankets, pillows, laundry detergent, bleach, toilet tissue and soap. The following are items a new Mariner would need to acquire:

  • Pair of Steel Toed Work Shoes or Work Boots
  • Pair of Steel Toed Rubber Boots
  • Slicker Suit (Rain Suit, top and bottom)
  • Personal Toiletries and Sanitation Items
  • Tobacco products to last longer than the entire work hitch (if applicable)
  • Cellular phone, phone card, envelopes, stamps or other means of staying in touch with family and friends

Personal supplies that consist of creams, powders or prescription medications must be approved by the vessel Captain and the Safety Department.




Our minimum qualifications for all offshore positions are a valid driver’s license, a high school graduate or GED, a Transportation Worker Identification Card (TWIC) or the ability to obtain a TWIC upon employment for the entry level Deckhand position, pass the USCG Merchant Mariner Physical and DOT drug and alcohol screening.
