Crew transfer vessels (CTVs) play a unique and important role in the maritime and offshore industries but what are crew transfer vessels exactly?
CTVs are robust ships that are specially designed to safely transport personnel between offshore vessels and ports, even in adverse weather conditions. In this guide, we take an in-depth look at how CTVs are used and how the process of crew transfer works.
How does crew transfer work?
Before we get into a detailed explanation of how a crew transfer works, let’s get clear on what a crew transfer is. A crew transfer refers to moving people and equipment to/from an offshore vessel, usually in one of following three scenarios:
- A crew member ‘signs on’ to join a ship from their home country
- A crew member ‘signs off’ to leave a ship to return to their home country
- A crew member moves from one vessel to another
There are several different reasons why a crew transfer might be necessary, such as medical emergencies, routine crew changes, repairs, or inspections.
How do crew transfer vessel services work?
While there are several different transfer methods, most typically crew transfer vessel services work in one of the following ways:
- Bump and jump
In this method, the crew transfer vessel positions itself bow-first against the j-tubes of a turbine access ladder. Using thrust, it is able to remain stationary so that crew can safely step over onto the access ladder. The ladder is set back from the j-tubes to create a safety zone so that, even if the vessel moves during transfer, crew will still be safe.
- Walk to Work
Walk to Work systems provide a longer window for crew to transfer. They work using a heave compensating bridging mechanism that attaches to the j-tubes or ladder, and keeps the bridge stationary relative to the turbine. This allows the crew to walk to work – just as the name suggests!
- Other new methods
As demands in the offshore sector change, so do the vessels that are being developed. For example, we are seeing larger vessels that can better withstand rough seas and carry larger loads. More fuel-efficient vessels are also being developed, such as those made using GRP (glass reinforced plastic). However, while these are lighter than the traditional aluminium vessels, they do come with other limitations.
What documentation do you require for a crew transfer?
When moving crew members between vessels and ports, it’s essential to have accurate and complete documentation in place. Not only does this ensure you are compliant with international rules, it helps avoid disruptions and facilitates smooth and efficient processes. Furthermore, a well-organised documentation management system is essential so that the required information can be accessed as/when needed. Let’s look at some of the key documents that are required for a crew transfer:
- Crew list
This document lists the name, position, nationality, and passport or seaman’s book number of every crew member onboard the vessel. It is vital that the crew list is always up to date in order to comply with port and immigration requirements.
- Immigration documents
Essential for smooth crew changes, immigration documents include a passport and an ILO-ratified seaman’s book (both must be valid for the full duration of the crew transfer), as well as a visa (where applicable), and shore passes. Every crew member, both on-signers and off-signers, must have these readily available to ensure they can move freely across borders. Failure to have the appropriate immigration documents for all crew members can lead to costly delays and other issues.
- Port clearance documents
When a vessel enters and/or exits a port, it’s necessary to prepare port clearance documents before the crew transfer. These include a vessel clearance certificate, customs clearance paperwork, and a cargo manifest.
- Crew transfer itinerary
Sometimes called a crew transfer plan, this document helps ensure safe and smooth operations. It details things like the date, time, location, and transfer method as well as the names and positions of crew members, and transport and accommodation arrangements.
